Littelfuse 0332008.VXP Ceramic Fuse Cartridge 8A 250VAC 125VDC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0332008.VXP is an 8 A ceramic fuse cartridge rated for 250 V AC and 125 V DC operation. This component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. The 3AB/3AG form factor (0.250" diameter × 1.250" length) requires a compatible fuse holder for installation. Substitute parts must preserve the fast-blow response characteristic and operating temperature range of -55°C to 125°C.

Substitute Part Grouping Explanation

Substitution of the obsolete 0332008.VXP is based on strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Current rating of 8 A
AC voltage rating of 250 V
DC voltage rating of 125 V
Ceramic cartridge fuse type with fast-blow response
3AB/3AG form factor with identical physical dimensions (0.250" Dia × 1.250" L)
Operating temperature range of -55°C to 125°C
ROHS3 compliance

The three active Littelfuse alternatives (0314008.VXP, 0314008.HXP, 0314008.MXP) belong to the Series 314 product line and meet all specified parameters. These parts are functionally equivalent to the obsolete Series 332 part and are suitable for direct replacement in applications requiring ceramic fuse cartridges with the stated electrical ratings and form factor.

Engineering Selection Recommendations

All three substitute parts (0314008.VXP, 0314008.HXP, 0314008.MXP) are active products from Littelfuse's Series 314 line and provide direct functional equivalence to the obsolete 0332008.VXP. Selection among these alternatives should be based on availability and regulatory compliance requirements for the target application.

The 0314008.VXP is the manufacturer-recommended substitute, offering the broadest certification coverage including UL, CSA, and KC approvals. The 0314008.HXP and 0314008.MXP are parametric equivalents with identical electrical characteristics and form factor, both carrying UL, CSA, and K-MARK certifications. All three parts maintain ROHS3 compliance and are suitable for applications requiring ceramic fuse cartridges with 8 A current rating and 250 V AC / 125 V DC voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can the 0314008.VXP, 0314008.HXP, and 0314008.MXP be used interchangeably with the 0332008.VXP?

A: Yes. All three substitute parts meet the identical electrical and mechanical specifications: 8 A current rating, 250 V AC / 125 V DC voltage ratings, ceramic cartridge construction with fast-blow response, and 3AB/3AG form factor (0.250" Dia × 1.250" L). They are direct replacements for the obsolete 0332008.VXP.

Q: What is the difference between the three substitute parts?

A: The 0314008.VXP, 0314008.HXP, and 0314008.MXP are electrically and mechanically identical. They differ only in regulatory certifications and availability. The 0314008.VXP carries UL, CSA, and KC approvals. The 0314008.HXP and 0314008.MXP carry UL, CSA, and K-MARK approvals.

Q: Do these fuses require a specific holder?

A: Yes. All parts in this family require a compatible 3AB or 3AG fuse holder for installation. The physical dimensions (0.250" diameter × 1.250" length) are standardized across all parts listed.

Q: Are these parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, meeting environmental and material restriction requirements.

Q: What is the operating temperature range for these fuses?
