Parameter Comparison

Engineering Selection Recommendations

032602.5HXP (Littelfuse Inc.) - Parametric Equivalent

This substitute maintains identical electrical and mechanical specifications to the 032602.5VXP. Both parts are from the Littelfuse 326 series and share the same current rating, voltage ratings, response time, and physical dimensions. Approval certifications are equivalent with minor designation variations (K-MARK vs. KC). This part is suitable for direct replacement in applications where the original specification is required.

BK/MDA-2-1/2-R (Eaton - Electronics Division) - Manufacturer Recommended

This substitute meets the primary electrical requirements of 2.5 A at 250 V AC with identical slow-blow response and ceramic cartridge construction. Physical dimensions and package form factors are identical. The part holds CE, CSA, and UL certifications. Differences include higher breaking capacity (200A vs. 100A AC), lower melting I²t value (7.2 vs. 136), and lower DC cold resistance (0.066 vs. 0.0835 Ohms). DC voltage rating is not specified for this part. Selection of this substitute should be based on application requirements for breaking capacity and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 032602.5HXP be used as a direct replacement for the 032602.5VXP?

A: Yes. Both parts are ceramic cartridge fuses with identical current ratings (2.5 A), AC voltage ratings (250 V), DC voltage ratings (125 V), response time (slow blow), and physical dimensions (0.250" Dia x 1.250" L). Both require holder-based installation and maintain ROHS3 compliance. The parts are electrically and mechanically interchangeable.

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

A: The Littelfuse 032602.5HXP is a parametric equivalent with identical specifications. The Eaton BK/MDA-2-1/2-R differs in breaking capacity (200A vs. 100A AC), melting I²t (7.2 vs. 136), and DC cold resistance (0.066 vs. 0.0835 Ohms). The Eaton part does not specify a DC voltage rating. Selection depends on whether the application requires the specific thermal and breaking capacity characteristics of the original part.

Q: Are all three parts compatible with the same holder?

A: Yes. All three parts use the 3AB, 3AG, 1/4" x 1-1/4" package form factor and require holder-based installation. Physical dimensions are identical across all three parts.

Q: What certifications apply to each substitute?

A: The 032602.5VXP holds CE, CSA, KC, PSE, and UL certifications. The 032602.5HXP holds CE, CSA, K-MARK, PSE, and UL certifications. The BK/MDA-2-1/2-R holds CE, CSA, and UL certifications. All three parts maintain ROHS3 compliance.

Q: Which substitute should I select for a new design?

A: Selection is based on application requirements. The 032602.5HXP provides identical performance to the original part. The BK/MDA-2-1/2-R is suitable when higher breaking capacity (200A) is required, but the lower melting I²t value and unspecified DC rating should be evaluated against circuit protection requirements.
