Summary: This document provides a complete drop-in cross-reference for migrating CalRamic Technologies, LLC CRT-0006 and CRT-0019 series high voltage leaded disc capacitors to HVC's product line. Coverage spans 3.2 kV to 20 kV across six dielectric families: N4700 (T3M), SL (N1500), Y5T (X7R), Y5U (Z5U), Y5T (X5R), and NP0 (COG). The guide includes 61 DigiKey-available standard parts and 38 extended-reference part numbers — 103 specifications in total — with detailed technical background on the CalRamic acquisition by HEICO/Exxelia and proven migration strategies.

1. Why Now? — The CalRamic Acquisition & Supply Chain Outlook

High voltage ceramic disc capacitors are mission-critical components in medical imaging (CT, X-ray), avionics, radar pulse-forming networks, and industrial high voltage power supplies. CalRamic Technologies, LLC (Reno, Nevada) has been a recognized specialist in leaded disc capacitors for over three decades, with its CRT-0006 and CRT-0019 series earning a reputation for reliable N4700 (T3M) low-loss dielectric performance in the 3 kV – 20 kV range.

1.1 The HEICO / Exxelia Acquisition — What Changed

On June 12, 2026, HEICO Corporation (NYSE: HEI) — through its subsidiary Exxelia — completed the acquisition of 90% of CalRamic Technologies' equity for $75.7 million in an all-cash transaction. This event reshapes the supply chain landscape in several critical ways:

• Consolidation into a MIL-qualified pricing tier: Exxelia targets $200M+ in annual revenues from defense and aerospace markets. CalRamic's product lines will be priced and prioritized within HEICO's military/aviation business hierarchy, potentially leaving commercial and industrial customers facing extended lead times and price premiums.
• Customer priority reshuffling: Large defense OEMs (Lockheed Martin, Raytheon, Northrop Grumman) typically receive preferential production scheduling. Smaller-volume commercial and industrial customers risk longer lead times and allocation constraints.
• Integration uncertainty: The first 12–18 months following a large-scale conglomerate acquisition typically involve restructuring, SKU rationalization, and personnel changes. Supply chain disruptions during this window are common.
• "Made in USA" premium without added value for non-defense applications: While the domestic production origin is valuable for ITAR-controlled programs, commercial and industrial buyers pay a premium that does not correlate with improved electrical performance or reliability.

1.2 A Pattern Recognized: HVC's Proven Migration Track Record

This is not the first major disruption in the high voltage ceramic capacitor market — and HVC has a well-documented history of successfully supporting engineers through each one.

The Murata Exit (2018–2021)

In August 2018, Murata Manufacturing announced the end-of-life of its DHS (Doorknob) high voltage capacitor series, officially exiting the HV ceramic capacitor market. By September 2021, the last DHS parts had shipped. The disruption was severe:

• Grey market prices spiked 300%–600% above original list price
• Production lines at multiple medical imaging OEMs were forced to halt awaiting allocation
• Standard lead times ballooned from 8 weeks to 24+ weeks

HVC's response: Between 2019 and 2022, HVC's HVCT8G doorknob series absorbed a significant portion of the Murata migration volume. Market share grew from <5% to >35% in the HV ceramic disc/doorknob segment. Qualification was completed with multiple Fortune 500 companies, including:

• GE Healthcare — Medical X-ray generator capacitors; reported 47× improvement in dissipation factor and passed IEC 60601-1 re-certification on first submission
• Nikon & Konica Minolta — Precision imaging equipment HV power supplies
• ABB — Smart grid FTU/DTU terminal units
• Baker Hughes — Industrial high voltage modules

The AVX Exit (2018)

Two months after Murata, AVX Corporation (now Kyocera AVX) announced its own exit from the HV doorknob capacitor market in October 2018. HVC subsequently qualified replacements for over 200 AVX HP/HW/HK models across 500+ global customers, with documented performance improvements:

• One medical OEM reported DF reduction from 0.7% to 0.015% (47× improvement) and a 7°C decrease in equipment internal temperature rise
• Equipment passed IEC 60601-1 medical safety re-certification on first submission after migration

Ongoing Vishay & TDK Lead Time Crisis

As of 2025–2026, Vishay and TDK high voltage capacitor lead times remain severely extended:

Manufacturer	Standard Lead Time	Specialty Items	HVC Comparison
Vishay (715C / 660R)	14–34 weeks	Up to 70–80 weeks	4–6 weeks
TDK (UHV / FHV)	14–34 weeks	Allocation-controlled	4–6 weeks

1.3 Why HVC for CalRamic Replacement?

Based on the above track record, HVC is positioned as the logical migration path for CalRamic's commercial and industrial customer base:

Supply Chain Challenge	HVC Solution	Measurable Advantage
Supply chain consolidation risk	Independent manufacturer, no acquisition dependency	4–6 week standard delivery
Price premium from MIL-tier pricing	Direct factory pricing, no defense markup	20%–40% BOM cost savings
Integration uncertainty (12–18 months)	Established production, mature quality system	Zero production interruption risk
Limited dielectric coverage	6 dielectric families covering all CalRamic types	103 drop-in replacements
Need for N4700 Class 1 performance	Genuine N4700 with DF ≤ 0.2%	Equivalent or superior electrical performance

All HVC replacement part numbers in this document are derived from actual specifications published in HVC's product catalog and validated against CalRamic's DigiKey-available data sheets. Part numbers marked with ★ are engineering-inferred extensions based on CalRamic's established part number encoding rules and filled to complete voltage/capacitance coverage gradients. These require HVC engineering confirmation before production ordering.

2. Dielectric Replacement Strategy Overview

CalRamic's CRT-0006 and CRT-0019 series employ six dielectric material families spanning both Class I (paraelectric) and Class II (ferroelectric) categories. The following table defines the precise dielectric-to-dielectric mapping for each CalRamic material code to the corresponding HVC product line:

CalRamic Dielectric	CalRamic Code	HVC Dielectric	HVC Code	Replacement Strategy & Engineering Rationale
N4700 (T3M)	CR17	N4700	DL	Direct material-to-material replacement; Class I paraelectric with DF ≤ 0.2% at 1 kHz; negative temperature coefficient optimized for RF pulse coupling and HV resonance applications
SL (N1500)	CR03	SL	SL	Same-material equivalent; Class I with approximately –1500 ppm/°C temperature coefficient; used in temperature compensation networks and HV measurement circuits
X7R	X	Y5T	D	Superior-grade Class II replacement; Y5T provides –30°C to +85°C operating range with ΔC/C ≤ ±22%, exceeding standard X7R performance specifications
Z5U	Z	Y5U	E	Same-class equivalent; Class II high-κ dielectric; +22%/–56% temperature characteristic suitable for power supply decoupling and coupling applications
X5R	W	Y5T	D	Performance upgrade; Y5T offers wider operating temperature range (–30°C to +85°C) compared to X5R (–30°C to +85°C), with superior DC bias characteristics
NP0 (COG)	N	NP0	N	Same-material Class I paraelectric; ultra-stable with ΔC/C ≤ ±30 ppm/°C; zero temperature coefficient; ideal for precision HV measurement, RF tuning, and low-loss resonance circuits

HVC Part Numbering Convention: All HVC replacement part numbers in this document carry the /T suffix, indicating that the dielectric has been calibrated and verified specifically for this CalRamic cross-reference application, ensuring precise temperature characteristic matching between the original and replacement components.

3. N4700 (T3M) Series — Complete Cross-Reference (CR17 Dielectric)

N4700 is CalRamic's primary Class I dielectric, widely deployed in CRT-0006 and CRT-0019 series for applications demanding low dissipation factor and stable dielectric performance across temperature. HVC's pure-phase N4700 Class 1 dielectric (DL series) is formulated from barium strontium titanate with controlled sintering to achieve DF ≤ 0.2% at 1 kHz — meeting or exceeding CalRamic's specified performance parameters.

5. Y5T (X7R) Series Cross-Reference

X7R is a Class II ferroelectric dielectric. CalRamic designates this with the X code. HVC replaces with Y5T (code D), which provides a superior temperature operating range (–30°C to +85°C with ΔC/C ≤ ±22%) exceeding standard X7R specifications. This upgrade is particularly beneficial for applications requiring stable capacitance across wider temperature extremes:
