Equivalent & Substitute Parts for HKP-J Fuse Holder

Part Overview

The HKP-J is a cartridge fuse holder manufactured by Eaton - Electronics Division, rated for 30 A at 250V with single-circuit panel mount configuration. This component is designed for use with 3AG cartridge fuses measuring 0.25" diameter by 1.26" length (6.35mm x 32mm). The HKP-J holds obsolete product status, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and system support applications where this holder type is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HKP-J is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Number of Circuits: 1 (exact match required)

Mechanical Parameters:

• Fuse Size: 0.25" Dia x 1.26" L / 6.35mm x 32mm (exact match required)
• Fuse Type: Cartridge (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Solder Lug (exact match required)
• Orientation: Horizontal and Vertical (exact match required)

Material & Contact Specifications:

• Contact Material: Brass (exact match required)
• Contact Finish: Tin (exact match required)

The substitute part PMA-KB-01H-SOS manufactured by OptiFuse meets all specified parameters and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PMA-KB-01H-SOS from OptiFuse is a direct functional equivalent to the obsolete HKP-J. Both components satisfy identical electrical and mechanical specifications across all critical parameters. The PMA-KB-01H-SOS carries active product status with current manufacturing support, whereas the HKP-J is obsolete. Both parts maintain ROHS3 compliance, meeting environmental regulatory requirements. The PMA-KB-01H-SOS is available in bulk packaging with 5425 units in current inventory, providing supply continuity for applications requiring 30 A, 250V single-circuit cartridge fuse holders with panel mount configuration and solder lug termination.

Frequently Asked Questions (FAQ)

Q: Can the PMA-KB-01H-SOS directly replace the HKP-J in existing applications?

A: Yes. The PMA-KB-01H-SOS meets all electrical and mechanical specifications of the HKP-J, including current rating, voltage rating, fuse size, mounting type, termination style, and contact materials. Direct substitution is supported.

Q: What is the significance of the HKP-J being obsolete?

A: Obsolete status indicates the HKP-J is no longer manufactured by Eaton. The PMA-KB-01H-SOS provides continued availability for applications requiring equivalent functionality, with active manufacturing status and established supply channels.

Q: Are there compliance differences between the two parts?

A: Both the HKP-J and PMA-KB-01H-SOS are ROHS3 compliant. No compliance barriers exist to substitution.

Q: Does packaging affect substitution suitability?

A: Packaging format (bulk for PMA-KB-01H-SOS versus the HKP-J specification) does not affect electrical or mechanical compatibility. Packaging is a procurement consideration only.

Q: What parameters must match exactly for substitution?

A: Current rating (30 A), voltage rating (250V), fuse size (0.25" x 1.26"), fuse type (cartridge), number of circuits (1), mounting type (panel mount), termination style (solder lug), orientation capability (horizontal and vertical), contact material (brass), and contact finish (tin) must all match exactly.
