V82ZC4P Equivalent & Substitute Parts

Part Overview

The V82ZC4P is a 82 V, 2.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the ZC series. This through-hole disc component (10mm) is designed for transient voltage protection in electronic circuits. The part is currently active in production with 732 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability constraints, supply chain considerations, or design flexibility within the same performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V82ZC4P is based on strict electrical and mechanical parameter matching within the Littelfuse varistor product line. The following criteria determine substitutability:

Critical Matching Parameters:

• Varistor voltage rating (82 V nominal, 73.8 V – 90.2 V range)
• Surge current capacity (2.5 kA)
• Energy absorption (8 J)
• Maximum AC/DC voltage ratings (50 V AC, 68 V DC)
• Mounting type (Through Hole)
• Package form factor (Disc 10mm)
• Operating temperature range (-55°C to 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The V82ZA4P qualifies as a parametric equivalent because it maintains identical electrical performance specifications and mechanical compatibility across all critical parameters, differing only in internal series designation (ZA vs. ZC).

Parameter Comparison

Engineering Selection Recommendations

Both the V82ZC4P and V82ZA4P are active production parts from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain requirements, as they are electrically and mechanically identical. The V82ZA4P currently has higher inventory availability (2290 units) compared to the V82ZC4P (732 units), making it suitable for high-volume procurement scenarios. Both parts meet the same regulatory and environmental compliance requirements and are suitable for direct substitution in circuit designs requiring 82 V transient voltage suppression with 2.5 kA surge capacity.

Frequently Asked Questions (FAQ)

Q: Can V82ZA4P be used as a direct replacement for V82ZC4P? A: Yes. The V82ZA4P is a parametric equivalent with identical electrical ratings (82 V nominal, 2.5 kA surge current, 8 J energy), identical mechanical specifications (through-hole, 10mm disc package), and identical compliance certifications (ROHS3, REACH Unaffected). Direct substitution is supported.

Q: What is the difference between the ZC and ZA series designations? A: The series designation (ZC vs. ZA) indicates internal product line classification within Littelfuse. Both series maintain identical performance specifications for this voltage and current rating. The difference does not affect electrical or mechanical compatibility.

Q: Are there any temperature or environmental differences between these parts? A: No. Both parts operate across the identical temperature range (-55°C to 85°C) and have the same moisture sensitivity level (MSL 1 - Unlimited). Environmental performance is equivalent.

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Both parts use identical through-hole mounting with 10mm disc package geometry. PCB footprints and assembly procedures are identical.

Q: What compliance certifications apply to both parts? A: Both V82ZC4P and V82ZA4P are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and HTSUS code 8533.40.4000.
