2. Materials & Process Comparison
2.1 Dielectric Material
Vishay 715C..KT and 660R (AZ prefix) use N4700 Class 1 ceramic. HVC HVCT8G-DL and HVCT9G-DL also employ N4700 dielectric, achieving equivalent performance in dielectric constant temperature stability, dissipation factor, and voltage coefficient. Vishay 715C..DK uses Y5U Class 2 ceramic; HVC covers this with the corresponding E-series, matching capacitance range and bias characteristics.
2.2 Electrode Process
Vishay 715C and 660R both use traditional silver electrode processes. HVC offers a copper electrode plating option, providing better high-voltage endurance and silver migration resistance, delivering more reliable performance under high-frequency pulse or high dV/dt stress.
2.3 Encapsulation Process
Vishay 715C uses epoxy molding encapsulation; 660R uses high-temp epoxy coating. HVC employs equivalent or superior epoxy systems, ensuring mechanical and electrical reliability across the -30°C ~ +85°C full temperature range.
3. Key Performance Parameter Comparison
| Parameter | Vishay 715C..KT | HVC HVCT8G (KT equivalent) | Difference |
|---|
| tan δ @ 1 kHz | ≤ 0.002 | ≤ 0.002 | Equivalent |
| IR @ 25°C | ≥ 10¹¹ Ω | ≥ 10¹¹ Ω | Equivalent |
| Temp Characteristic | N4700: ±2.0% / -30~85°C | N4700 same grade | Equivalent |
| Partial Discharge | Model-dependent | Controllable < 5 pC | Comparable |
| Terminal Torque | 12 inch-pounds max | Equal or higher | Compatible |
4. Success Cases: Vishay Replacement Projects
4.1 Vishay 715C Replacement (CO2 Laser Power Supply)
A European laser equipment manufacturer originally used Vishay 715C40KTD10 (40kV 1000pF) as the key voltage-multiplier capacitor in CO2 laser power supplies. When Vishay lead times extended from 8 to 22 weeks, production was halted. HVC provided HVCT8G-40KV-DL40-102K as replacement:
- Samples delivered within 2 weeks.
- PD test passed (< 5 pC @ 50% rated voltage).
- Volume pricing approximately 30% lower.
- Continuous supply maintained for 3 subsequent years.
4.2 Vishay 660R Replacement (Medical X-Ray Power Supply)
A North American medical equipment company originally used Vishay 660R20AZD10 (20kV 1000pF N4700) in X-ray HV power supply modules. HVC provided HVCT9G-20KV-DL30-681K for replacement:
- Axial lead parameters fully matched.
- 100% withstand voltage test passed.
- Temperature cycling test (-30°C ~ +85°C) qualified.
- Customer has transitioned to dual-source supply.
5. Selection Recommendations
| Scenario | Recommended Solution | Rationale |
|---|
| Urgent 715C screw terminal replacement | HVCT8G-DL (KT eq.) / HVCT8G-E (DK eq.) | 4~6 week lead time, equivalent performance |
| Urgent 660R axial lead replacement | HVCT9G-DL (N4700) / HVCT9G-X (X7R) / HVCT9G-E (Z5U) | Full 10~30kV coverage |
| Low loss, high stability | HVCT8G-DL / HVCT9G-DL (N4700) | tan δ ≤ 0.002 |
| High capacitance needed | HVCT8G-E / HVCT9G-E (Y5U/Z5U eq.) | Up to 20 nF |
