V07E175 Equivalent & Substitute Parts

Part Overview

The V07E175 is a 270 V, 1.75 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the UltraMOV™ series. This component is designed for single-circuit through-hole applications in a 7mm disc package format. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this specification is required.

Substitute Part Grouping Explanation

Substitute parts for the V07E175 are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

Varistor voltage (typical): 270 V
Surge current rating: 1.75 kA
Maximum AC voltage: 175 V
Maximum DC voltage: 225 V
Number of circuits: 1
Mounting type: Through hole
RoHS3 compliance

Acceptable Variations:

Varistor voltage range: 243 V to 303 V (minimum to maximum across all qualified parts)
Package/case dimensions: 7mm to 8.5mm disc
Energy absorption: 17 J to 24 J
Operating temperature: -55°C to -40°C minimum; 85°C maximum
Capacitance values within specified frequency ranges

The V07E175P (Littelfuse) and ERZ-V07D271 (Panasonic) meet these criteria and are qualified as direct substitutes.

Engineering Selection Recommendations

V07E175P (Littelfuse Inc.) is the primary substitute for the obsolete V07E175. Both parts are from the same manufacturer and UltraMOV™ series, with identical electrical specifications and 7mm disc packaging. The V07E175P is currently in active production status with confirmed inventory availability. This part maintains full compatibility with existing PCB layouts and mechanical mounting requirements. ROHS3 compliance and REACH unaffected status are confirmed.

ERZ-V07D271 (Panasonic Electronic Components) is a qualified alternative substitute from a different manufacturer. This part meets all primary electrical criteria with identical surge current (1.75 kA) and voltage ratings. The package dimension increases to 8.5mm disc, which requires verification of available PCB space. The ERZ-V07D271 offers higher energy absorption (24 J versus 17 J) and operates within a narrower minimum temperature range (-40°C versus -55°C). This part is actively produced with substantial inventory availability. ROHS3 compliance and REACH unaffected status are confirmed.

Selection between V07E175P and ERZ-V07D271 depends on PCB layout constraints and thermal operating requirements. For applications requiring the full -55°C minimum temperature specification, V07E175P is the appropriate choice. For applications with -40°C minimum temperature tolerance and available PCB space for the larger 8.5mm package, ERZ-V07D271 provides equivalent electrical performance with higher energy absorption capability.

Frequently Asked Questions (FAQ)

Q: Can V07E175P be used as a direct replacement for V07E175 without PCB modifications?

A: Yes. V07E175P is electrically and mechanically identical to V07E175, with the same 7mm disc package and through-hole mounting configuration. No PCB layout changes are required.

Q: What is the primary difference between V07E175P and ERZ-V07D271?

A: The primary differences are package size (7mm versus 8.5mm disc), energy absorption (17 J versus 24 J), and minimum operating temperature (-55°C versus -40°C). Electrical voltage and surge current ratings are identical.

Q: Does ERZ-V07D271 require PCB modifications for installation?

A: The 8.5mm disc package is larger than the original 7mm package. PCB layout verification is required to confirm adequate space for the larger component footprint. Through-hole mounting remains compatible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. V07E175P and ERZ-V07D271 are both ROHS3 compliant. Both parts are also REACH unaffected.

Q: Which substitute part should be selected for applications operating below -40°C?

A: V07E175P must be selected for applications requiring operation at -55°C minimum temperature. ERZ-V07D271 is rated to -40°C minimum and is not suitable for lower temperature environments.

Q: What is the inventory status of substitute parts?

A: V07E175P has 820 pieces in stock. ERZ-V07D271 has 11,892 pieces in stock. Both are actively produced and available for procurement.
