2. HVC Replacement Engineering-Grade Technical Analysis
2.1 HVCT8G Series (Replacing 715C Screw Terminal)
The HVC HVCT8G series is specifically designed to replace the 715C series, delivering the following technical upgrades in materials and processes:
- N4700 Class 1 Ceramic: KT-equivalent models use the same N4700 dielectric as Vishay 715C..KT, with tan δ ≤ 0.002 @ 1 kHz and minimal capacitance voltage coefficient — ideal for resonant circuits and low-loss applications.
- Copper Electrode Process: Replaces traditional silver electrodes, offering superior high-voltage endurance and silver migration resistance.
- Thread Compatibility: Standard #8-32 UNC-2B threaded hole, fully compatible with Vishay 715C; M4/M5 metric terminal options also available.
- Y5U Coverage: DK-equivalent models use Y5U Class 2 ceramic, covering 300 pF~20 nF high-capacitance range.
- PD Control: Corona limit < 5 pC @ 50% rated AC voltage per specification.
2.2 HVCT9G Series (Replacing 660R Encapsulated Axial Lead)
The HVCT9G series is HVC's dedicated replacement for Vishay's 660R encapsulated axial lead disc capacitors:
- Full coverage of N4700 (Class 1), X7R (Class 2) and Z5U (Class 2) dielectric types.
- Axial lead packaging, highly compatible with 660R mounting pitch and dimensions.
- Complete coverage across 10~30 kVDC four voltage grades.
- Lead specification matches: tin-plated copper-clad steel, equivalent to Vishay 660R's 20 AWG.
- Custom lead length and special lead configurations supported.
3. Class 1 vs Class 2: Selection Decision Tree
| Application Requirement | Recommended Dielectric | Vishay Equivalent | HVC Equivalent |
|---|
| Low loss, HF, high stability | N4700 (Class 1) | 715C..KT / 660R (AZ prefix) | HVCT8G-DL / HVCT9G-DL |
| Mid-value capacitance, line filter | X7R (Class 2) | 660R (AC prefix) | HVCT9G-X |
| High capacitance, bypass/decoupling | Y5U / Z5U (Class 2) | 715C..DK / 660R (AE prefix) | HVCT8G-E / HVCT9G-E |
| High AC withstand required | N4700 (Class 1) | 715C..KT (higher AC rating) | HVCT8G-DL |
| PD testing required | Class 2 Y5U (DK has PD spec) | 715C..DK | HVCT8G-E |
4. Key Steps for Replacement Verification
- Parameter Alignment: Verify voltage (DC/AC RMS), capacitance, tolerance, dielectric TCC.
- Mounting Verification: 715C — check thread spec (#8-32 vs M4/M5) and torque limit (12 inch-pounds); 660R — check lead pitch and PCB hole diameter.
- PD Testing: Partial discharge test in oil-immersed or air-gap environment to verify corona limit.
- Creepage Distance Assessment: Evaluate terminal-to-terminal creepage distance per safety requirements based on system voltage.
- Thermal Cycling: Verify capacitance temperature characteristics across -30°C ~ +85°C full temperature range.

Technical data sourced from Vishay official datasheets Document 22168 (715C..DK), 22210 (715C..KT), 22209 (660R), and HVC official product catalog. Class 1 and Class 2 capacitors cannot be interchanged solely by capacitance and voltage — temperature coefficient and bias characteristics must be considered.
