Substitute Part Grouping Explanation

Substitution of the 0325.010H is based on strict equivalence across all critical electrical and mechanical parameters. The substitute parts 0325.010HXP, 0325.010MXP, and 0325.010VXP maintain identical specifications for current rating (10 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package format (3AB, 3AG), breaking capacity (100 A), melting I²t (0.00148), and physical dimensions (0.275" Dia x 1.288" L). These parts differ only in product status (active versus obsolete) and compliance certifications, making them direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0325.010HXP, 0325.010MXP, 0325.010VXP) are functionally equivalent to the 0325.010H across all critical electrical and mechanical parameters. The primary distinction is product status: the original part is obsolete, while all substitutes are active components with current manufacturing support. The substitute parts carry CE approval and ROHS3 compliance certification, whereas the original part lacks specified approval agency documentation and is RoHS non-compliant. For new designs or component replacement in applications requiring regulatory compliance, any of the three active substitute parts is suitable. Selection among the three substitutes may be based on packaging preference (all are supplied in bulk) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 0325.010HXP, 0325.010MXP, or 0325.010VXP be used as direct replacements for the 0325.010H?

A: Yes. All three parts maintain identical electrical ratings (10 mA, 250 V AC), fuse type (ceramic cartridge), response time (slow blow), breaking capacity (100 A), melting I²t (0.00148), and physical dimensions (0.275" Dia x 1.288" L). They are mechanically and electrically interchangeable in through-hole 3AB and 3AG package applications.

Q: What is the difference between the three substitute parts?

A: The 0325.010HXP, 0325.010MXP, and 0325.010VXP are parametrically identical. All differences are non-functional: they share the same product status (active), compliance certifications (CE, ROHS3), and operating temperature range (-55°C ~ 125°C). Selection may be based on inventory availability or packaging lot preferences.

Q: Why is the original 0325.010H classified as obsolete?

A: The 0325.010H is listed as obsolete, indicating it is no longer in active production. The active substitute parts provide equivalent functionality with current manufacturing support and updated compliance certifications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The substitute parts are identical in package format (3AB, 3AG, 1/4" x 1-1/4" axial), mounting type (through hole), and all electrical specifications. They are direct pin-for-pin and functionally equivalent replacements.

Q: What certifications do the substitute parts carry?

A: All three substitute parts carry CE approval and are ROHS3 compliant. They also maintain REACH unaffected status. The original 0325.010H lacks specified approval agency documentation and is RoHS non-compliant.
