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.

Since 2022, Vishay's HVCC/715C/660R series have faced severe supply chain constraints:

* Lead Time Crisis: Standard delivery extended to 14–34 weeks, with specialized items reaching 70–80 weeks. Many production lines have been forced to shut down awaiting Vishay allocation.

* Premium Pricing: As a Western multinational brand, Vishay commands the highest unit pricing among comparable HV ceramic capacitors.

* Allocation Bias: Large Tier-1 OEM customers receive priority scheduling; small-to-medium enterprises face chronic supply uncertainty.

HVC's value proposition addresses every pain point:

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.
