ERZ-VEAV271 Equivalent & Substitute Parts

Part Overview

The ERZ-VEAV271 is a 270 V varistor manufactured by Panasonic Electronic Components, designed for transient voltage suppression applications. This through-hole disc component (10mm) provides surge current protection rated at 4.6 kA with 49 J energy absorption capability. The part is actively produced, AEC-Q200 qualified for automotive applications, and maintains REACH compliance. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERZ-VEAV271 is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (247–303 V range)
• Surge current capacity (4.6 kA minimum)
• Energy absorption (49 J)
• Capacitance specification (350 pF @ 1 kHz)
• Operating temperature range (−40 to +85°C)
• Mounting configuration (through-hole)
• Package form factor (disc 10mm)
• Number of circuits (1)

The ERZ-VA9V271 meets all substitution criteria. Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance specifications and mechanical dimensions. The primary difference is packaging format: ERZ-VEAV271 is supplied in Tape & Box (TB) configuration, while ERZ-VA9V271 is supplied in Cut Tape (CT) configuration. This distinction affects procurement and assembly workflows but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both ERZ-VEAV271 and ERZ-VA9V271 are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and supply requirements:

• ERZ-VEAV271 (Tape & Box): Suitable for applications requiring bulk packaging and standard inventory management practices.
• ERZ-VA9V271 (Cut Tape): Suitable for automated assembly processes and applications where cut-tape format aligns with production workflows.

Both parts maintain AEC-Q200 automotive qualification and REACH compliance. The ERZ-VA9V271 carries RoHS3 compliance certification. Component selection should align with procurement specifications, assembly equipment compatibility, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ERZ-VA9V271 be used as a direct replacement for ERZ-VEAV271 in circuit design?

A: Yes. Both parts are electrically and mechanically identical. They share the same varistor voltage rating (270 V typical), surge current capacity (4.6 kA), energy absorption (49 J), and physical form factor (disc 10mm through-hole). The only difference is packaging format (Tape & Box versus Cut Tape), which does not affect component performance.

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

A: Tape & Box (TB) packaging supplies components on continuous tape wound in a box, typically used for manual assembly and standard inventory storage. Cut Tape (CT) packaging supplies components on tape segments, optimized for automated pick-and-place assembly systems. Both formats contain identical components.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ERZ-VEAV271 and ERZ-VA9V271 carry AEC-Q200 qualification, confirming suitability for automotive-grade applications. The ERZ-VA9V271 additionally carries RoHS3 compliance certification.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching varistor voltage range (247–303 V), surge current rating (4.6 kA), energy absorption (49 J), capacitance (350 pF @ 1 kHz), and operating temperature range (−40 to +85°C). Both parts meet these criteria.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts use identical through-hole mounting configuration and disc 10mm package dimensions. No PCB layout modifications are required for substitution.
