V82ZA2 Equivalent & Substitute Parts

Part Overview

The V82ZA2 is an 82 V, 1.2 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 7mm package. This component is designed for transient voltage protection in electronic circuits with a rated energy capacity of 4J and operating temperature range of -55°C to 85°C.

The V82ZA2 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V82ZA2 is determined by strict equivalence across the following critical parameters:

• Varistor Voltage (Typical): 82 V nominal rating
• Current - Surge Rating: 1.2 kA minimum capacity
• Energy Rating: 4 J minimum
• Mounting Type: Through Hole configuration
• Package / Case: Disc 7mm form factor
• Number of Circuits: Single circuit (1)
• Operating Temperature Range: -55°C to 85°C minimum
• RoHS Compliance: ROHS3 Compliant

The V82ZA2P is a direct manufacturer equivalent from Littelfuse Inc., differing only in packaging format (Bulk vs. standard) and product status (Active vs. Obsolete). All electrical and mechanical parameters remain identical.

Cross-manufacturer substitutes (ERZ-V07D820, B72207S0500K101) must meet or exceed all parameters listed above to ensure functional compatibility and circuit protection performance.

Parameter Comparison

Engineering Selection Recommendations

The V82ZA2P is the primary substitute for the obsolete V82ZA2. Both parts are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications. The V82ZA2P carries Active product status, ensuring ongoing availability and supply chain support. Both parts are ROHS3 Compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements.

For applications requiring continued support and component availability, the V82ZA2P is the recommended direct replacement. Cross-manufacturer alternatives (ERZ-V07D820, B72207S0500K101) may be considered only when all specified parameters are confirmed to meet or exceed the requirements of the original V82ZA2 design.

Frequently Asked Questions (FAQ)

Q: Can the V82ZA2P be used as a direct replacement for the V82ZA2?

A: Yes. The V82ZA2P is electrically and mechanically identical to the V82ZA2. The only differences are packaging format and product status. The V82ZA2P is the active production equivalent.

Q: What are the critical parameters for substituting this varistor?

A: The varistor voltage rating (82 V typical), surge current capacity (1.2 kA), energy rating (4 J), through-hole mounting type, and disc 7mm package form factor must all be maintained. Operating temperature range (-55°C to 85°C) and RoHS compliance status must also be preserved.

Q: Are there packaging differences between V82ZA2 and V82ZA2P?

A: The V82ZA2P is supplied in Bulk packaging, while the V82ZA2 uses standard packaging. This is a supply and distribution difference only; electrical and mechanical performance are identical.

Q: What does the obsolete status of the V82ZA2 mean?

A: Obsolete status indicates that Littelfuse Inc. has discontinued production of the V82ZA2. The V82ZA2P (Active status) is the current production equivalent and should be used for new designs and ongoing supply requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the V82ZA2 and V82ZA2P are ROHS3 Compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special storage or handling requirements.
