Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HKP-EL-ZZ is determined by strict equivalence across the following critical parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Fuse Size: 0.25" Dia x 1.26" L / 6.35mm x 32mm (exact match required)
• Fuse Type: Cartridge (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Solder Lug (exact match required)
• Contact Material: Brass (exact match required)
• Contact Finish: Tin (exact match required)

The substitute part PMA-KB-01H-SOS from OptiFuse meets all specified electrical and mechanical parameters, enabling direct functional equivalence in applications currently utilizing the HKP-EL-ZZ.

Parameter Comparison

Engineering Selection Recommendations

The PMA-KB-01H-SOS from OptiFuse is a direct functional equivalent to the obsolete HKP-EL-ZZ. Both components share identical electrical ratings (30 A, 250V), mechanical dimensions (0.25" x 1.26"), and interface specifications (solder lug termination, brass tin-plated contacts). Both parts maintain ROHS3 compliance, satisfying regulatory requirements for new designs and legacy system updates.

The primary distinction is product status: the HKP-EL-ZZ is obsolete, while the PMA-KB-01H-SOS is active with confirmed inventory availability (5425 pieces in stock). For applications requiring the HKP-EL-ZZ specification, the PMA-KB-01H-SOS provides continuity of supply without electrical or mechanical redesign.
