Littelfuse 032603.2VXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 032603.2VXP is a 3.2 A, 250 V AC/DC ceramic cartridge fuse with slow-blow response characteristics. This fuse is designed for applications requiring circuit protection in the 3AB, 3AG form factor (1/4" x 1-1/4"). The part maintains active product status with full compliance to international safety standards including CE, CSA, KC, PSE, and UL certifications. Substitute parts are identified based on matching electrical ratings, mechanical dimensions, and functional performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 032603.2VXP are qualified based on the following critical parameters:

• Current Rating: 3.2 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Product Status: Active (current availability)
• RoHS Compliance: ROHS3 Compliant (environmental standard match)

Two substitute parts meet these criteria: the Littelfuse 032603.2HXP (parametric equivalent) and the Eaton BK/MDA-3-2/10-R (manufacturer-recommended equivalent).

Parameter Comparison

Engineering Selection Recommendations

All three parts—032603.2VXP, 032603.2HXP, and BK/MDA-3-2/10-R—are active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following factors:

Littelfuse 032603.2HXP: This part is a direct parametric equivalent to the 032603.2VXP, manufactured by the same supplier. Both parts share identical electrical ratings, mechanical dimensions, melting I²t values, and DC cold resistance. The 032603.2HXP carries the same approval agencies (CE, CSA, PSE, UL) with K-MARK certification in place of KC. This part is suitable for direct substitution in applications where the original part is specified.

Eaton BK/MDA-3-2/10-R: This part meets all critical electrical and mechanical requirements (3.2 A, 250 V, slow-blow ceramic cartridge, 3AB/3AG package). It carries CE, CSA, and UL certifications. The Eaton part exhibits lower DC cold resistance (0.045 Ohms versus 0.0539 Ohms) and a significantly lower melting I²t value (17.5 versus 214). These differences indicate different thermal response characteristics. The Eaton part is suitable for applications where cross-manufacturer substitution is acceptable and thermal response variations are compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 032603.2HXP be used as a direct replacement for the 032603.2VXP?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical current ratings (3.2 A), voltage ratings (250 V), fuse type (ceramic cartridge), response time (slow blow), mechanical dimensions (0.250" Dia x 1.250" L), and melting I²t values (214). Both are ROHS3 compliant and carry equivalent safety certifications. The 032603.2HXP is a parametric equivalent suitable for direct substitution.

Q: What are the key differences between the Littelfuse and Eaton fuses?

A: The Littelfuse 032603.2VXP and 032603.2HXP share identical specifications. The Eaton BK/MDA-3-2/10-R differs in two measurable parameters: DC cold resistance (0.045 Ohms versus 0.0539 Ohms) and melting I²t (17.5 versus 214). These differences reflect different thermal response characteristics. All three parts meet the same electrical ratings and mechanical package requirements.

Q: Are all three parts mechanically compatible with 3AB and 3AG fuse holders?

A: Yes. All three parts conform to the 3AB, 3AG package specification with dimensions of 0.250" Dia x 1.250" L (6.35mm x 31.75mm). They are mechanically interchangeable in holders designed for this form factor.

Q: Which certifications are common across all substitute parts?

A: All three parts carry CE, CSA, and UL certifications. The Littelfuse 032603.2VXP additionally carries KC and PSE certifications. The Littelfuse 032603.2HXP carries K-MARK and PSE certifications. The Eaton BK/MDA-3-2/10-R carries only CE, CSA, and UL certifications. Selection should account for regional certification requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts—032603.2VXP, 032603.2HXP, and BK/MDA-3-2/10-R—are ROHS3 compliant and REACH unaffected.
