Littelfuse 0332006.VXP Ceramic Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0332006.VXP is a 6 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation with fast-blow response characteristics. This component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct circuit substitution.

Substitute Part Grouping Explanation

Substitution of the obsolete 0332006.VXP (Series 332) is based on electrical and mechanical parameter equivalence with active Littelfuse Series 314 alternatives. All substitute parts maintain identical current rating (6 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), physical dimensions (1/4" x 1-1/4"), and holder compatibility (3AB, 3AG). The three substitute part numbers—0314006.VXP, 0314006.HXP, and 0314006.MXP—differ only in regional approval agency certifications and packaging format, with all variants classified as active products. Substitution is valid where the holder assembly remains unchanged and circuit protection requirements align with the specified electrical parameters.

Engineering Selection Recommendations

All three substitute parts (0314006.VXP, 0314006.HXP, 0314006.MXP) are direct functional equivalents of the obsolete 0332006.VXP. Selection among the three active alternatives is determined by regional regulatory requirements and approval agency compliance:

0314006.VXP is recommended for applications requiring CSA, KC, and UL certifications in addition to CE and PSE compliance.

0314006.HXP and 0314006.MXP are functionally identical to 0314006.VXP and are recommended where K-MARK certification is required in place of KC certification, or where regional approval requirements align with the CSA, K-MARK, PSE, and UL certification set.

All substitute parts maintain ROHS3 compliance and operate across the identical temperature range (-55°C to 125°C). Physical dimensions and holder compatibility remain unchanged, ensuring direct mechanical fit within existing fuse holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can 0314006.VXP, 0314006.HXP, and 0314006.MXP be used interchangeably in place of 0332006.VXP?

A: Yes. All three substitute parts maintain identical electrical ratings (6 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), physical dimensions (1/4" x 1-1/4"), and holder compatibility (3AB, 3AG). Substitution is valid for direct circuit replacement.

Q: What is the difference between the three substitute part numbers?

A: The three parts differ only in regional approval agency certifications. 0314006.VXP includes KC certification; 0314006.HXP and 0314006.MXP include K-MARK certification. All other electrical and mechanical parameters are identical.

Q: Will the substitute parts fit in the existing fuse holder?

A: Yes. All substitute parts maintain the same physical dimensions (0.250" diameter x 1.250" length) and are compatible with 3AB and 3AG holder assemblies.

Q: Are there any performance differences between the main part and the substitutes?

A: The substitute parts are from the active Series 314 line and maintain all specified electrical parameters. Breaking capacity ratings are higher in the substitute parts (750 A AC, 10 kA DC versus 100 A in the main part), which does not affect compatibility for direct substitution.

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

A: All parts operate across -55°C to 125°C, maintaining consistent performance across the specified temperature range.
