Equivalent & Substitute Parts for V14E175

Part Overview

The V14E175 is a 270 V, 6 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the UltraMOV™ series. This component is designed for single-circuit transient voltage suppression applications with a through-hole disc mounting configuration of 14mm. The V14E175 is currently listed as obsolete, making identification of active substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V14E175 is determined by the following critical parameters:

• Maximum AC Volts: 175 V
• Maximum DC Volts: 225 V
• Varistor Voltage (Typical): 270 V
• Current - Surge: 6 kA
• Number of Circuits: 1
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these core electrical and mechanical requirements. The V14E175P is an identical Littelfuse component with the same electrical specifications and packaging, differentiated only by bulk packaging and active product status. The ERZ-V14D271 from Panasonic Electronic Components matches all critical electrical parameters but features a slightly larger disc diameter (15.5mm versus 14mm) and operates across a narrower temperature range (-40°C to 85°C versus -55°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

The V14E175P is the primary substitute for the V14E175. Both components are manufactured by Littelfuse, share identical electrical specifications, and maintain the same 14mm disc package footprint. The V14E175P is currently in active production status with higher inventory availability, making it the preferred choice for direct replacement in existing designs without PCB modification.

The ERZ-V14D271 from Panasonic Electronic Components is a secondary substitute suitable for applications where the slightly larger 15.5mm disc diameter can be accommodated on the PCB. This component provides higher energy absorption (99 J versus 70 J) and operates within a narrower temperature range (-40°C to 85°C). The ERZ-V14D271 is also in active production status with substantial inventory availability.

Both substitute parts maintain ROHS3 compliance and are classified under the same ECCN and HTSUS codes as the original component, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the V14E175P be used as a direct replacement for the V14E175?

A: Yes. The V14E175P is electrically and mechanically identical to the V14E175, with the same 14mm disc package, electrical ratings, and operating temperature range. The only difference is packaging format and active product status.

Q: What is the primary difference between the V14E175P and ERZ-V14D271?

A: The ERZ-V14D271 has a larger disc diameter (15.5mm versus 14mm) and higher energy absorption (99 J versus 70 J). It also operates across a narrower temperature range (-40°C to 85°C versus -55°C to 85°C). All core electrical parameters—maximum AC/DC volts, surge current, and typical varistor voltage—remain identical.

Q: Will the ERZ-V14D271 fit in the same PCB footprint as the V14E175?

A: The ERZ-V14D271 has a 15.5mm disc diameter compared to the 14mm diameter of the V14E175. PCB layout verification is required to confirm mechanical fit. If space constraints exist, the V14E175P is the recommended substitute.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the V14E175P and ERZ-V14D271 are ROHS3 compliant, matching the compliance status of the original V14E175.

Q: What is the inventory status of these substitute parts?

A: The V14E175P has 2,275 pieces in stock, and the ERZ-V14D271 has 6,575 pieces in stock, both listed as new original inventory.
