Equivalent & Substitute Parts for Eaton HKP-JJ Fuse Holder

Part Overview

The Eaton HKP-JJ is a cartridge fuse holder rated for 30 A at 250V with single-circuit panel mount configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance and repair operations. The HKP-JJ accommodates 3AG cartridge fuses in 0.25" diameter by 1.26" length format with horizontal and vertical mounting orientation capability. Solder lug termination and brass tin-finished contacts provide standard electrical connection and corrosion resistance for industrial control panel applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HKP-JJ is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

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

The OptiFuse PMA-KB-01H-SOS meets all critical parameters required for direct functional substitution. Both components accommodate identical 3AG cartridge fuses, operate at the same electrical ratings, and provide equivalent mechanical mounting and termination characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OptiFuse PMA-KB-01H-SOS cartridge fuse holder provides functional equivalence to the obsolete Eaton HKP-JJ across all critical electrical and mechanical parameters. Both components are ROHS3 compliant and accommodate identical 3AG fuse formats at 30 A and 250V ratings.

The primary distinction between these components is product status: the HKP-JJ is obsolete while the PMA-KB-01H-SOS maintains active production status. This status difference ensures continued availability and supply chain reliability for the OptiFuse alternative.

Both components feature identical solder lug termination, brass tin-finished contacts, and panel mount configuration with horizontal and vertical orientation capability. Electrical performance and mechanical interface characteristics are equivalent for direct substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

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

A: Yes. Both fuse holders accommodate identical 3AG cartridge fuses, operate at 30 A and 250V, feature solder lug termination, and support horizontal and vertical mounting orientations. Electrical and mechanical specifications are equivalent.

Q: What is the significance of the product status difference between these components?

A: The HKP-JJ is classified as obsolete, indicating discontinued manufacturing and limited availability. The PMA-KB-01H-SOS maintains active production status, ensuring reliable supply for new installations and replacement requirements.

Q: Are both components RoHS compliant?

A: Yes. Both the Eaton HKP-JJ and OptiFuse PMA-KB-01H-SOS are ROHS3 compliant, meeting environmental and material restriction requirements for industrial applications.

Q: What fuse types are compatible with these holders?

A: Both holders accommodate 3AG cartridge fuses in 0.25" diameter by 1.26" length format. This standardized fuse size ensures interchangeability across both holder models.

Q: Are there differences in packaging between these components?

A: The OptiFuse PMA-KB-01H-SOS is supplied in bulk packaging. The HKP-JJ packaging specification is not provided in available documentation. Packaging format does not affect electrical or mechanical compatibility.
