Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 0332001.HXP is based on strict equivalence of the following critical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating: 250 V AC / 125 V DC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" × 1-1/4" (exact match required)
• Physical Dimensions: 0.250" Dia × 1.250" L (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—0314001.HXP, 0314001.MXP, and 0314001.VXP—are direct functional equivalents of the obsolete 0332001.HXP. Each substitute maintains identical electrical ratings, mechanical dimensions, and holder compatibility.

The substitute parts are manufactured by Littelfuse Inc. and classified as active products with current production status. All substitutes carry expanded regulatory approvals including CSA and UL certifications in addition to CE and PSE, providing enhanced compliance coverage for international applications.

Selection among the three active substitutes may be based on inventory availability and supply chain considerations, as all three parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can 0314001.HXP, 0314001.MXP, and 0314001.VXP be used interchangeably with 0332001.HXP?

A: Yes. All three substitute parts meet identical electrical specifications (1 A, 250 V AC / 125 V DC, fast-blow response) and mechanical requirements (3AB/3AG holder compatibility, 0.250" Dia × 1.250" L dimensions). They are direct functional equivalents.

Q: What is the primary reason for substitution?

A: The 0332001.HXP is classified as obsolete. The active substitute parts (0314001 series) provide equivalent functionality with current manufacturing availability and expanded regulatory certifications.

Q: Are there any differences in regulatory approvals between the main part and substitutes?

A: The substitute parts carry broader regulatory approvals (CE, CSA, PSE, UL) compared to the main part (CE, cULus, PSE). This provides enhanced compliance for applications requiring CSA or UL certification.

Q: Do the substitute parts fit existing 3AB and 3AG fuse holders?

A: Yes. All substitute parts maintain the identical 3AB, 3AG package specification and 0.250" diameter × 1.250" length dimensions, ensuring direct mechanical compatibility with existing holders.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts, including 0314001.HXP, 0314001.MXP, and 0314001.VXP, are ROHS3 compliant.
