Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERZ-VGAD271 is based on the following electrical and mechanical parameters:

• Varistor voltage specification: 270 V nominal (247 V – 303 V range)
• Surge current capability: 4.6 kA minimum
• Energy dissipation: 49 J minimum
• Operating voltage limits: 175 V AC / 225 V DC maximum
• Capacitance: 350 pF @ 1 kHz
• Operating temperature range: -40°C to +85°C
• Mounting configuration: Through-hole disc 10mm package
• Number of circuits: Single circuit (1)

The ERZ-VA9V271 meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ERZ-VGAD271 and ERZ-VA9V271 are active products from Panasonic Electronic Components with identical electrical specifications and mechanical form factors. The ERZ-VGAD271 carries AEC-Q200 automotive qualification. Both parts are REACH Unaffected and classified under ECCN EAR99. Selection between these parts should be based on packaging requirements: the ERZ-VGAD271 is supplied in Tape & Box format, while the ERZ-VA9V271 is supplied in Cut Tape format. The ERZ-VA9V271 carries RoHS3 compliance certification. Both parts are suitable for equivalent circuit protection applications where the specified electrical and thermal parameters are required.

Frequently Asked Questions (FAQ)

Q: Can the ERZ-VA9V271 be used as a direct replacement for the ERZ-VGAD271?

A: Yes. Both parts have identical varistor voltage specifications (270 V nominal), surge current ratings (4.6 kA), energy dissipation (49 J), operating temperature ranges (-40°C to +85°C), and through-hole disc 10mm package configurations. Electrical performance is equivalent.

Q: What is the difference between these two parts?

A: The primary differences are packaging format and compliance certifications. The ERZ-VGAD271 is supplied in Tape & Box format and carries AEC-Q200 automotive qualification. The ERZ-VA9V271 is supplied in Cut Tape format and carries RoHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist for applications requiring the specified electrical parameters. Both parts are through-hole mounted in identical 10mm disc packages and have matching pin configurations for single-circuit applications. Verify that your procurement and supply chain requirements align with the available packaging formats.

Q: Which part should I select for automotive applications?

A: The ERZ-VGAD271 is qualified to AEC-Q200 automotive standards. If automotive qualification is a requirement, the ERZ-VGAD271 is the specified choice. The ERZ-VA9V271 is suitable for non-automotive applications requiring equivalent electrical performance.

Q: What is the significance of the packaging format difference?

A: Tape & Box (TB) packaging is typically used for manual assembly and smaller production volumes. Cut Tape (CT) packaging is used for automated pick-and-place assembly systems. Select based on your assembly process requirements.
