Littelfuse V07E150 Varistor - Equivalent & Substitute Parts

Part Overview

The Littelfuse V07E150 is a 240 V, 1.75 kA disc varistor from the UltraMOV™ series, designed for transient voltage suppression in through-hole applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance requirements. Substitute parts must maintain identical electrical performance across voltage ratings, surge current capacity, and energy absorption specifications while accommodating packaging variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

• Varistor voltage range (216–264 V typical 240 V)
• Surge current capacity (1.75 kA minimum)
• Maximum AC and DC voltage ratings (150 V AC / 200 V DC)
• Number of circuits (1 circuit)
• Mounting type (through hole)
• Operating temperature range (−55 to +85°C or wider)
• RoHS3 compliance

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Littelfuse): Parts V07E150P and V07E150PX2855 are active production variants of the obsolete V07E150, maintaining identical electrical specifications and disc form factor. These differ only in packaging configuration (bulk vs. tape/reel).

Parametric Cross-Manufacturer Equivalent (Panasonic): Part ERZ-V07D241 meets all critical electrical parameters but uses a larger disc package (8.5 mm vs. 7 mm) and higher energy rating (21 J vs. 15 J). This part is suitable only where mechanical envelope constraints permit the larger package.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select V07E150P or V07E150PX2855. Both are active production parts from Littelfuse with identical electrical and mechanical specifications to the obsolete V07E150. These parts are ROHS3 compliant and maintain the same 7 mm disc package, ensuring compatibility with existing PCB layouts and through-hole footprints. V07E150P is supplied in bulk packaging; V07E150PX2855 is supplied in tape/reel format. Selection between these two depends on procurement and assembly requirements.

For Cross-Manufacturer Substitution: The Panasonic ERZ-V07D241 is electrically equivalent across all critical parameters (voltage ratings, surge current, operating temperature range) and is ROHS3 compliant. However, this part uses an 8.5 mm disc package compared to the 7 mm package of the original. This substitution is valid only when the larger mechanical envelope can be accommodated on the PCB without layout conflicts or thermal management issues. The higher energy rating (21 J vs. 15 J) provides additional margin but does not affect compatibility.

Frequently Asked Questions (FAQ)

Q: Can V07E150P be used as a direct replacement for the obsolete V07E150?

A: Yes. V07E150P is an active production equivalent with identical electrical specifications, voltage ratings, surge current capacity, and 7 mm disc package. The only difference is packaging format (bulk vs. original configuration). No circuit redesign is required.

Q: What is the difference between V07E150P and V07E150PX2855?

A: Both parts are electrically and mechanically identical. The difference is packaging: V07E150P is supplied in bulk; V07E150PX2855 is supplied in tape/reel format. Selection depends on assembly process requirements and procurement preferences.

Q: Can the Panasonic ERZ-V07D241 replace the Littelfuse V07E150?

A: Electrical substitution is valid. The ERZ-V07D241 meets all voltage, current, and temperature specifications. However, the 8.5 mm disc package is larger than the 7 mm package of the V07E150. Verify that the larger package fits within the available PCB space and does not interfere with adjacent components or thermal management.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. V07E150P, V07E150PX2855, and ERZ-V07D241 are all ROHS3 compliant, matching the compliance status of the obsolete V07E150.

Q: What is the operating temperature range difference between the Littelfuse and Panasonic parts?

A: Littelfuse parts (V07E150, V07E150P, V07E150PX2855) operate from −55 to +85°C. The Panasonic ERZ-V07D241 operates from −40 to +85°C. If the application requires operation below −40°C, use a Littelfuse part.

Q: Does the higher energy rating of the ERZ-V07D241 (21 J vs. 15 J) affect circuit compatibility?

A: No. Higher energy absorption capacity does not create compatibility issues. It provides additional transient suppression margin and does not alter the electrical interface or voltage clamping characteristics.
