What is HVC's TCO (Total Cost of Ownership) advantage when replacing major brand HV capacitors?

HVC Capacitor delivers comprehensive TCO savings extending far beyond unit price: 20-40% BOM cost reduction, 5x faster lead time (4-6w vs 14-34w), lower inventory carrying cost, zero allocation line-down risk, and <0.1% field failure rate — quantified annual savings up to 62% on total procurement budget.

Cost Component	Vishay Scenario	HVC Scenario	Annual Savings
Unit Cost	$140,000	$95,000	$45,000
Expedited Freight	$12,000	$1,200	$10,800
Inventory Carrying	$18,667	$7,000	$11,667
Line-Down Risk	$100,000	$0	$100,000
Total Annual TCO	$270,667	$103,200	$167,467 (62%)

Parameter	HVC Genuine N4700 (T3M)	SAMWHA Specification N4700	Performance Gap
Dielectric Class	Class 1 Paraelectric (SrTiO₃-based)	Transitional Grade (Class 1/2 hybrid)	Fundamental material difference
Dissipation Factor (DF)	≤0.1% – 0.2% @ 1kHz	1.0% max (datasheet)	5x – 10x higher losses in SAMWHA
Insulation Resistance	≥200,000 MΩ (typical)	≥10,000 MΩ → ≥5,000 MΩ (post-test)	20x – 40x lower IR
Temperature Coefficient	±4.7% (true N4700)	±4.7% (nominal)	Similar on paper
Aging Effect	None (Class 1 characteristic)	Present (Class 2 behavior)	Long-term drift concern
Flash Test Voltage	150% – 200% of rated	130% of rated (20kV models only)	Lower safety margin
Life Test Standard	125% rated voltage aging	110% rated voltage aging (20kV)	Reduced lifespan validation
SAMWHA Dielectric	Series Code	HVC Replacement	Strategy
N4700 (labeled)	N / ECN	N4700 (DL)	Same code, genuine material upgrade
Y5R	R / EKR	N4700 (DL) ↑	Material upgrade: Y5R → real N4700
Y5P	B / EKB	Y5T (D)	Equivalent grade replacement
Y5U	E / EKE	Y5U (E)	Same material replacement
Y5V	F / EKF	Y5V (F)	Same material replacement
SL	O / ECO	SL (SL)	Same material replacement

Total coverage: Approximately 118 SAMWHA model specifications from 10kV to 50kV are mapped to HVC equivalents with upgraded materials wherever possible.
