HKP-W-R Cartridge Fuse Holder Equivalent & Substitute Parts

Part Overview

The HKP-W-R is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications with a 30 A current rating at 250V. This component accommodates 0.25" diameter by 1.26" length cartridge fuses (6.35mm x 32mm) and features a single circuit configuration with solder lug termination.

The HKP-W-R is classified as obsolete. Identification of equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this fuse holder specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HKP-W-R is determined by electrical and mechanical parameter equivalence. The following parameters must remain constant for direct substitution:

• 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
• RoHS Compliance: ROHS3 Compliant

The substitute part BK/HKP-W-R meets all these electrical and mechanical requirements and is manufactured by the same supplier (Eaton - Electronics Division) within the same HKP series.

Parameter Comparison

Engineering Selection Recommendations

The BK/HKP-W-R is the direct substitute for the obsolete HKP-W-R. Both components are manufactured by Eaton - Electronics Division and share identical electrical and mechanical specifications across all critical parameters.

The BK/HKP-W-R holds Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and carry the same ECCN and HTSUS classifications, confirming regulatory and trade equivalence.

The BK/HKP-W-R is suitable for direct replacement in applications currently specified for the HKP-W-R without modification to circuit design, PCB layout, or assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the BK/HKP-W-R be used as a direct replacement for the HKP-W-R?

A: Yes. The BK/HKP-W-R is electrically and mechanically equivalent to the HKP-W-R. Both components share identical current rating (30 A), voltage rating (250V), fuse size (0.25" Dia x 1.26" L), mounting type (panel mount), and termination style (solder lug). No circuit modifications are required.

Q: Why is the HKP-W-R listed as obsolete?

A: The HKP-W-R has been discontinued by Eaton - Electronics Division. The BK/HKP-W-R remains in active production and serves as the current equivalent for this fuse holder specification.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. The BK/HKP-W-R includes REACH Unaffected status. These differences do not affect functional substitution.

Q: What fuse types are compatible with these holders?

A: Both the HKP-W-R and BK/HKP-W-R accommodate 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (0.25" Dia x 1.26" L / 6.35mm x 32mm).

Q: Are the contact materials and finishes identical?

A: Yes. Both components feature brass contacts with tin finish, ensuring equivalent electrical performance and corrosion resistance.
