V07E320P Equivalent & Substitute Parts

Part Overview

The V07E320P is a 510 V, 1.75 kA varistor manufactured by Littelfuse Inc. in the UltraMOV™ series. This transient voltage suppressor is designed for through-hole mounting in a 7mm disc package and is classified as Active with ROHS3 compliance. Equivalent and substitute parts are identified when they maintain the same electrical performance characteristics (voltage rating, surge current, energy absorption) and mechanical compatibility (mounting type, package form factor) as the original component.

Engineering Selection Recommendations

All substitute parts listed maintain electrical equivalence to the V07E320P across the critical parameters: varistor voltage (510 V typical), surge current (1.75 kA), and maximum voltage ratings (320 V AC / 410–420 V DC).

B72207S2321K101 (EPCOS - TDK Electronics): Identical electrical specifications and 7mm package form factor. Extended operating temperature range (-40°C to 105°C) provides broader thermal capability. ROHS3 compliant with high inventory availability.

ERZ-V07D511 (Panasonic Electronic Components): Meets all electrical requirements with increased energy absorption (45 J vs. 32 J). Package form factor is 8.5mm disc, requiring verification of mechanical fit in the application. ROHS3 compliant.

MOVHE07V320Y (Eaton - Electronics Division): Electrical specifications equivalent with highest energy absorption (45 J) and widest operating temperature range (-40°C to 125°C). 7mm package form factor matches original. ROHS3 compliant. Supplied in bag packaging rather than bulk.

All parts carry Active product status and meet regulatory compliance requirements (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can B72207S2321K101 be used as a direct replacement for V07E320P?

A: Yes. Both parts share identical varistor voltage (510 V typical), surge current (1.75 kA), maximum voltage ratings (320 V AC / 420 V DC), and 7mm disc package form factor. The EPCOS part offers an extended operating temperature range (-40°C to 105°C vs. -55°C to 85°C).

Q: What is the difference between the ERZ-V07D511 and the original V07E320P?

A: The Panasonic ERZ-V07D511 matches all electrical specifications but uses an 8.5mm disc package instead of 7mm. The larger package diameter may affect mechanical fit in space-constrained applications. Energy absorption is higher (45 J vs. 32 J).

Q: Is the MOVHE07V320Y compatible with the V07E320P?

A: Yes, electrically and mechanically. The Eaton part maintains the 7mm disc package and all critical electrical parameters. It offers the highest energy absorption (45 J) and widest temperature range (-40°C to 125°C). Packaging is supplied in bags rather than bulk.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitutes are ROHS3 compliant, REACH Unaffected, and classified as EAR99 under ECCN. All carry Active product status.

Q: Which substitute should I select if thermal performance is critical?

A: The MOVHE07V320Y offers the widest operating temperature range (-40°C to 125°C). The B72207S2321K101 provides an extended upper temperature limit (-40°C to 105°C) compared to the original V07E320P (-55°C to 85°C).

Q: Are there package form factor constraints I should consider?

A: Yes. The V07E320P, B72207S2321K101, and MOVHE07V320Y all use 7mm disc packages and are mechanically interchangeable. The ERZ-V07D511 uses an 8.5mm disc package and requires verification of fit within the application's PCB layout and component spacing.
