Littelfuse V82ZC2P Equivalent & Substitute Parts

Part Overview

The Littelfuse V82ZC2P is a 82 V, 1.2 kA metal oxide varistor (MOV) designed for transient voltage suppression applications. This through-hole disc component (7mm) provides single-circuit protection in bulk packaging. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V82ZC2P is permissible when the following electrical and mechanical parameters are maintained:

• Varistor voltage nominal rating: 82 V (within tolerance range 73.8 V – 90.2 V)
• Surge current capacity: 1.2 kA minimum
• Energy absorption: 4 J minimum
• Maximum AC voltage rating: 50 V minimum
• Maximum DC voltage rating: 68 V minimum
• Mounting configuration: Through hole
• Package form factor: Disc 7mm
• Operating temperature range: -55°C to +85°C minimum
• Compliance certifications: RoHS3 and REACH status maintained

The V82ZC2P belongs to the Littelfuse ZC series. Parametric equivalents within the Littelfuse product family that satisfy all above criteria are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The V82ZA2P is a direct parametric equivalent to the V82ZC2P. Both components are manufactured by Littelfuse, maintain identical electrical specifications across all critical parameters, and share the same mechanical form factor (Disc 7mm through-hole). Both parts carry active product status and full compliance certifications (RoHS3 and REACH unaffected).

Selection between V82ZC2P and V82ZA2P is determined by availability and supply chain requirements. The V82ZA2P currently maintains higher inventory levels (20,310 pcs vs. 699 pcs), making it suitable for applications where component sourcing is a consideration. Both parts are suitable for direct substitution in 82 V transient voltage suppression circuits without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the V82ZA2P replace the V82ZC2P in existing designs?

A: Yes. The V82ZA2P is a parametric equivalent with identical electrical ratings (82 V nominal, 1.2 kA surge current, 4 J energy), matching mechanical package (Disc 7mm through-hole), and equivalent compliance certifications. No circuit modifications are required.

Q: What is the difference between the ZC and ZA series designations?

A: The ZC and ZA designations identify different product series within the Littelfuse varistor family. Both series share identical electrical and mechanical specifications for the 82 V, 1.2 kA rating. Series designation does not affect functional performance or substitutability.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both the V82ZC2P and V82ZA2P operate across the identical temperature range (-55°C to +85°C) and carry the same moisture sensitivity level (MSL 1 – Unlimited). Environmental performance is equivalent.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS3 compliant and REACH unaffected. They carry identical regulatory status and are suitable for applications requiring these certifications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both components use identical through-hole mounting configuration and Disc 7mm package form factor. PCB footprints and assembly procedures remain unchanged during substitution.
