Can HVC provide direct alternatives for Vishay 715C and 660R series high voltage ceramic capacitors?

Yes — HVC Capacitor offers complete pin-to-pin compatible replacements for Vishay's Cera-Mite 715C series (screw terminal doorknob, 10–50kV) and 660R series (encapsulated axial-lead disc, 10–30kV), with over 100 precisely matched 1:1 replacement models.

Vishay Series	Voltage Range	HVC Replacement	Key Improvement
715C.DK / 715C..KT	10kV – 50kV DC	HVCT8G series (screw terminal)	N4700 dielectric upgrade from Y5U
660R series	10kV – 30kV DC	HVCT9G series (axial-lead encapsulated)	Smaller footprint, higher IR
Parameter	Vishay 715C/660R	HVC HVCT8G/HVCT9G	Advantage
Lead Time	14 – 34 weeks	4 – 6 weeks	5x faster
BOM Cost	Baseline (high)	20% – 40% savings	Significant reduction
Dielectric Material	Class 2 (Y5U/Y5S)	Class 1 N4700 (T3M)	Lower DF, better stability
Dissipation Factor	0.5% – 1.5% typical	≤0.2% @ 1kHz	5x – 10x lower losses
Insulation Resistance	≥10,000 MΩ	≥200,000 MΩ	20x higher
Flash Test Margin	130% of rated	150% – 200% of rated	Higher safety margin

Since the 2018 Murata/AVX market exit, HVC has successfully completed qualification validation with multiple Fortune 500 companies including:

* GE Healthcare — Medical X-ray generator capacitors

* Nikon & Konica Minolta — Precision imaging equipment

* ABB — Smart grid FTU/DTU terminal units

* Baker Hughes — Industrial high-voltage modules

All replacements maintain identical mounting dimensions (#8-32 UNC-2B thread standard for 715C → HVCT8G) requiring zero PCB redesign in most applications.
