BK/HKP-CC Fuse Holder Cartridge 250V 20A Panel Mount - Equivalent & Substitute Parts

Part Overview

The BK/HKP-CC is a cartridge fuse holder manufactured by Eaton - Electronics Division, rated for 20 amperes at 250 volts 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 BK/HKP-CC carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and new design applications where this fuse holder specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/HKP-CC are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain functionally equivalent across all substitute candidates:

Critical Matching Parameters:

• Current Rating: 20 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
• Fuseholder Type: Holder

Acceptable Variation Parameters:

• Contact Material (Brass or Copper Alloy acceptable)
• Contact Finish (Tin finish maintained across all substitutes)
• Termination Style (Quick Connect with minor connector dimension variations permitted within 0.250" to 0.187" range for compatible quick-connect standards)
• Packaging format (Bulk or standard packaging)
• RoHS/REACH compliance status (newer substitutes may have improved compliance)

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

BK/HKP-CC-R (Eaton - Electronics Division) is the primary direct substitute for the obsolete BK/HKP-CC. Both components share identical electrical ratings (20A, 250V), mechanical dimensions (0.25" x 1.26"), and termination specifications (Quick Connect 0.250"). The BK/HKP-CC-R maintains the same HKP series designation and contact material (Brass with Tin finish). The critical distinction is product status: BK/HKP-CC-R is active and carries ROHS3 compliance certification, whereas the original BK/HKP-CC is obsolete and RoHS non-compliant. For applications requiring regulatory compliance or long-term component availability, BK/HKP-CC-R is the recommended replacement.

03453LF2H (Littelfuse) is a cross-manufacturer equivalent that satisfies all critical electrical and mechanical parameters. This part maintains identical current rating (20A), voltage rating (250V), fuse size (0.25" x 1.26"), and mounting configuration (panel mount, single circuit). The 03453LF2H differs in termination connector dimension (0.187" versus 0.250") and contact material (Copper Alloy versus Brass), but both materials provide equivalent electrical performance with tin finish. The 03453LF2H is active and ROHS3 compliant. Selection of this part requires verification that the 0.187" quick-connect termination is compatible with existing mating connectors in the target application.

Frequently Asked Questions (FAQ)

Q: Can BK/HKP-CC-R be used as a direct replacement for BK/HKP-CC without any modifications?

A: Yes. BK/HKP-CC-R is a direct substitute with identical electrical ratings (20A, 250V), mechanical dimensions (0.25" x 1.26"), and termination style (Quick Connect 0.250"). No circuit modifications are required. The primary difference is improved product status (active versus obsolete) and regulatory compliance (ROHS3 versus non-compliant).

Q: What is the key difference between BK/HKP-CC-R and 03453LF2H?

A: Both parts meet the core electrical and mechanical requirements (20A, 250V, 0.25" x 1.26" cartridge, panel mount). The primary differences are: (1) Termination connector size: BK/HKP-CC-R uses 0.250" quick-connect, while 03453LF2H uses 0.187" quick-connect; (2) Contact material: BK/HKP-CC-R uses Brass, 03453LF2H uses Copper Alloy; (3) Manufacturer: Eaton versus Littelfuse. Selection depends on mating connector compatibility in your application.

Q: Is the 0.187" termination connector on the 03453LF2H compatible with the 0.250" connector on the original BK/HKP-CC?

A: The termination connector dimensions differ (0.187" versus 0.250"). Compatibility depends on the mating connector specification in your application. Verify that your existing quick-connect receptacles accept the 0.187" pin size before selecting the 03453LF2H.

Q: Are all three parts (BK/HKP-CC, BK/HKP-CC-R, 03453LF2H) compatible with 3AG cartridge fuses?

A: Yes. All three fuse holders are designed for use with 3AG cartridge fuses measuring 0.25" diameter by 1.26" length (6.35mm x 32mm). Fuse compatibility is identical across all three parts.

Q: What is the significance of RoHS compliance for these fuse holders?

A: BK/HKP-CC is RoHS non-compliant, while BK/HKP-CC-R and 03453LF2H are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, BK/HKP-CC-R or 03453LF2H must be selected. The original BK/HKP-CC may only be used in applications where RoHS exemptions apply.

Q: Which substitute part should I select for a new design?

A: For new designs, select BK/HKP-CC-R if your application uses 0.250" quick-connect terminations, or 03453LF2H if your application uses 0.187" quick-connect terminations. Both are active products with ROHS3 compliance. Verify termination connector compatibility with your mating components before final selection.

Q: Are there inventory considerations when selecting between BK/HKP-CC-R and 03453LF2H?

A: Current inventory levels are: BK/HKP-CC-R (1082 pcs), 03453LF2H (899 pcs), and BK/HKP-CC (902 pcs). All three parts are available in stock. For long-term supply assurance, BK/HKP-CC-R is recommended due to its active product status and Eaton manufacturer support.
