Littelfuse V8ZC2 Varistor - Equivalent & Substitute Parts

Part Overview

The Littelfuse V8ZC2 is a transient voltage suppressor varistor rated at 8.5 V nominal voltage with 250 A surge current capacity. This component is designed for single-circuit through-hole applications in a 10mm disc package format. The V8ZC2 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The V8ZC2P qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Varistor voltage range: 6 V (Min) to 11 V (Max), with 8.5 V typical
• Surge current capacity: 250 A
• Maximum DC voltage rating: 5.5 V
• Maximum AC voltage rating: 4 V
• Energy dissipation: 0.8 J
• Number of circuits: 1
• Mounting configuration: Through Hole
• Package format: Disc 10mm
• Operating temperature range: -55°C to 85°C
• Capacitance specification: 7000 pF @ 1 MHz

The V8ZC2P maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The V8ZC2P is the appropriate substitute for the obsolete V8ZC2. Both components are manufactured by Littelfuse Inc. and belong to the ZC series varistor line. The V8ZC2P maintains full electrical and mechanical compatibility while offering the advantage of active product status and current manufacturing support.

The V8ZC2P carries ROHS3 compliance certification, meeting environmental regulatory requirements. The transition from V8ZC2 to V8ZC2P involves no design modifications, as all critical parameters—voltage ratings, surge current capacity, energy dissipation, thermal range, and package geometry—remain identical.

Frequently Asked Questions (FAQ)

Q: Can V8ZC2P be used as a direct replacement for V8ZC2 without circuit modifications?

A: Yes. The V8ZC2P is electrically and mechanically identical to the V8ZC2 across all specified parameters. No circuit design changes are required.

Q: What is the primary difference between V8ZC2 and V8ZC2P?

A: The V8ZC2 is obsolete, while the V8ZC2P maintains active product status. The packaging designation differs (unspecified for V8ZC2 versus Bulk for V8ZC2P), but electrical performance and through-hole disc 10mm package format are identical.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The V8ZC2P includes REACH Unaffected status documentation. Both carry identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What parameters must remain constant for substitution validity?

A: Varistor voltage range (6–11 V typical 8.5 V), surge current (250 A), DC/AC voltage ratings (5.5 V / 4 V), energy dissipation (0.8 J), mounting type (through hole), and package format (disc 10mm) must all match.

Q: Is the V8ZC2P available in higher inventory quantities?

A: Yes. The V8ZC2P shows 1118 pieces in stock compared to 681 pieces for the obsolete V8ZC2, providing improved supply chain reliability.
