Substitute Part Grouping Explanation

The Littelfuse 0313.175HXP qualifies as a direct substitute for the 0313.175MXP based on identical electrical and mechanical parameters. Both parts share the same current rating (175 mA), voltage rating (250 V AC), response time classification (slow blow), physical dimensions (0.250" Dia x 1.250" L), holder compatibility (3AB, 3AG), breaking capacity (35 A), melting I²t value (0.177), operating temperature range (-55°C to 125°C), and regulatory certifications (CE, CSA, UL). The substitution is valid across all specified parameters without performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the 0313.175MXP and 0313.175HXP are active products manufactured by Littelfuse Inc. with identical regulatory certifications (CE, CSA, UL) and ROHS3 compliance. Selection between these parts should be based on inventory availability and procurement lead times, as all electrical, mechanical, and compliance parameters are equivalent. Both parts are suitable for direct substitution in 3AB and 3AG holder applications requiring 175 mA protection at 250 V AC/DC.
