V10E175 Equivalent & Substitute Parts

Part Overview

The V10E175 is a 270V 4.6kA disc varistor from Littelfuse Inc.'s UltraMOV™ series, designed for transient voltage suppression in through-hole applications. This part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. The varistor provides single-circuit protection with a 10mm disc package and operates across a temperature range of -55°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V10E175 is determined by the following critical parameters:

• Maximum AC Volts: 175 V
• Maximum DC Volts: 225 V
• Varistor Voltage (Typ): 270 V
• Current - Surge: 4.6 kA
• Number of Circuits: 1
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Substitute parts must maintain these electrical specifications and through-hole mounting configuration. Package dimensions may vary within mechanical compatibility constraints. The following parts meet these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

V10E175P is the primary substitute for the obsolete V10E175. Both parts are manufactured by Littelfuse Inc., share identical electrical specifications, and are packaged in the same 10mm disc format. V10E175P is currently in active production with higher inventory availability (6493 pcs vs. 718 pcs for the original part). Both parts maintain ROHS3 compliance and identical operating temperature ranges.

ERZ-V10D271 from Panasonic Electronic Components is a secondary substitute that meets all critical electrical parameters. This part features a larger 11.5mm disc package and higher energy rating (49J vs. 35J). The operating temperature range is narrower (-40°C to 85°C vs. -55°C to 85°C). ERZ-V10D271 is suitable for applications where the increased package size and higher energy capacity do not present mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can V10E175P be used as a direct replacement for V10E175?

A: Yes. V10E175P is electrically and mechanically identical to V10E175, with the same 10mm disc package, voltage ratings, surge current capacity, and operating temperature range. The primary difference is product status: V10E175P is active production while V10E175 is obsolete.

Q: What are the key differences between V10E175P and ERZ-V10D271?

A: Both parts share identical maximum AC/DC voltage ratings and surge current capacity. ERZ-V10D271 differs in three areas: (1) package size is 11.5mm disc versus 10mm disc, (2) energy rating is 49J versus 35J, and (3) operating temperature minimum is -40°C versus -55°C. The varistor voltage tolerance range is slightly wider for ERZ-V10D271 (247-303V vs. 243-297V).

Q: Will ERZ-V10D271 fit in a PCB designed for the 10mm V10E175?

A: The 11.5mm package of ERZ-V10D271 is larger than the 10mm package of V10E175. Physical fit depends on PCB layout constraints. Verify available space before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. V10E175P and ERZ-V10D271 are both ROHS3 compliant, matching the compliance status of the original V10E175.

Q: Which substitute should be selected for new designs?

A: V10E175P is recommended for direct replacement in existing designs due to identical package and specifications. For new designs with no package constraints, ERZ-V10D271 offers higher energy capacity and active production status from an alternative manufacturer.
