Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0332002.VXP is determined by strict equivalence across the following parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating AC: 250 V (exact match required)
• Voltage Rating DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute parts listed below satisfy all electrical and mechanical parameters. The primary distinction between the main part and substitutes is product status: the 0332002.VXP is obsolete, while all substitute parts are active production items from Littelfuse Inc. Series 314.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—0314002.VXP, 0314002.HXP, and 0314002.MXP—are direct functional equivalents to the obsolete 0332002.VXP. Each substitute maintains identical electrical ratings, mechanical dimensions, and mounting requirements.

The substitute parts offer enhanced regulatory compliance compared to the main part. While the 0332002.VXP carries CE, cULus, and PSE approvals, all three substitutes include CSA and UL certifications in addition to CE and PSE, providing broader market acceptance and regulatory coverage.

All substitute parts are active production items with confirmed inventory availability and ROHS3 compliance status. Selection among the three substitutes may be based on packaging preference (all listed as Bulk) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 0314002.VXP, 0314002.HXP, and 0314002.MXP be used interchangeably with the 0332002.VXP?

A: Yes. All three substitute parts are parametric equivalents with identical current ratings (2 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and mechanical dimensions (1/4" x 1-1/4"). They are direct replacements for the obsolete 0332002.VXP.

Q: What is the primary difference between the main part and the substitutes?

A: The 0332002.VXP is classified as obsolete, while all three substitute parts are active production items from Littelfuse Series 314. The substitutes also provide expanded regulatory certifications (CSA and UL) compared to the main part.

Q: Do these fuses require a specific holder?

A: Yes. All parts in this comparison require a holder compatible with the 3AB and 3AG package standards. The 1/4" x 1-1/4" form factor is standard for this holder type.

Q: Are there differences in electrical performance between the substitute parts?

A: All substitute parts meet the same electrical specifications for current and voltage ratings. Differences in melting I²t values and DC cold resistance are provided specifications but do not affect functional equivalence for the stated 2 A, 250 V AC / 125 V DC application.

Q: What certifications apply to these fuses?

A: The 0332002.VXP carries CE, cULus, and PSE approvals. The substitute parts (0314002.VXP, 0314002.HXP, 0314002.MXP) carry CE, CSA, PSE, and UL approvals, providing broader regulatory coverage.
