V82ZT4P Equivalent & Substitute Parts

Part Overview

The V82ZT4P is a 82 V, 2.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (10mm). This component is designed for transient voltage protection in electronic circuits and is currently in active production status. Finding equivalent substitute parts is necessary when the primary packaging format (Tape & Reel) is unavailable or when alternative packaging configurations better suit procurement or assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V82ZT4P is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Varistor voltage rating: 82 V (minimum 73.8 V, typical 82 V, maximum 90.2 V)
• Surge current capacity: 2.5 kA
• Maximum DC voltage: 68 V
• Maximum AC voltage: 50 V
• Energy dissipation: 8 J
• Number of circuits: 1
• Mounting configuration: Through Hole
• Physical package: Disc 10mm
• Operating temperature range: -55°C to 85°C
• Compliance certifications: ROHS3, REACH Unaffected

The V82ZS4P qualifies as a parametric equivalent because it maintains identical electrical specifications and physical form factor. The only difference is the packaging format (Cut Tape versus Tape & Reel), which does not affect component performance or compatibility in the circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the V82ZT4P and V82ZS4P are active production components from Littelfuse Inc. with identical electrical performance and physical specifications. Selection between these parts should be based on procurement and assembly requirements:

The V82ZT4P in Tape & Reel packaging is suitable for high-volume automated assembly operations. The V82ZS4P in Cut Tape packaging is appropriate for lower-volume applications, manual assembly, or when component-level flexibility is required.

Both parts maintain full ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across all markets. The choice between packaging formats does not impact circuit performance, reliability, or compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can V82ZS4P be used as a direct replacement for V82ZT4P in production?

A: Yes. The V82ZS4P is electrically and mechanically identical to the V82ZT4P. The only difference is packaging format (Cut Tape versus Tape & Reel). Both components have identical electrical specifications, physical dimensions, and compliance certifications. Substitution is valid for any application where the V82ZT4P is specified.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual handling or lower-volume assembly. Both formats contain the same component with identical performance characteristics.

Q: Are there any thermal or electrical performance differences between these substitute parts?

A: No. Both the V82ZT4P and V82ZS4P maintain identical operating temperature ranges (-55°C to 85°C), surge current capacity (2.5 kA), varistor voltage rating (82 V typical), and energy dissipation (8 J). Performance in circuit applications is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the V82ZT4P and V82ZS4P are ROHS3 compliant and REACH Unaffected. They carry identical regulatory certifications and are suitable for use in regulated markets without additional qualification.

Q: What should I consider when selecting between these packaging options?

A: Consider your assembly process: Tape & Reel is preferred for automated high-volume production with pick-and-place equipment. Cut Tape is preferred for manual assembly, prototyping, or applications requiring component-level flexibility. Both deliver identical circuit performance.
