BK-HKL-EX Fuse Holder Cartridge 250V 15A Panel Mount

Part Overview

The BK-HKL-EX is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications with a 15 A current rating at 250V. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing procurement and system maintenance. The fuse holder accommodates 3AG cartridge fuses with dimensions of 0.25" diameter by 1.26" length (6.35mm x 32mm) and features quick connect termination for 0.250" (6.3mm) connections.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK-HKL-EX is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 15 A
• Voltage Rating: 250V
• Number of Circuits: 1

Mechanical Parameters:

• Fuse Size: 0.25" Dia x 1.26" L (6.35mm x 32mm)
• Mounting Type: Panel Mount
• Fuse Type: Cartridge

Interface Parameters:

• Termination Style compatibility with system requirements

The substitute part BK-HKL-X maintains identical electrical and mechanical specifications to the BK-HKL-EX. The primary distinction is product status: BK-HKL-X is active and available, whereas BK-HKL-EX is obsolete. The termination style differs between the two parts (Quick Connect versus Solder Lug), which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

BK-HKL-X is the direct substitute for BK-HKL-EX based on electrical and mechanical parameter equivalence. The BK-HKL-X is currently active and maintains full compatibility with the 15 A, 250V cartridge fuse holder application requirements.

Critical Consideration: The termination style differs between the two parts. BK-HKL-EX uses Quick Connect - 0.250" (6.3mm) termination, while BK-HKL-X uses Solder Lug termination. System integration must accommodate this interface difference. If the original circuit design requires quick connect termination, alternative solutions or circuit modification may be necessary.

Both parts carry identical RoHS non-compliance status and MSL rating, indicating no change in regulatory or environmental handling requirements during substitution.

Frequently Asked Questions (FAQ)

Q: Can BK-HKL-X directly replace BK-HKL-EX in all applications?

A: BK-HKL-X matches all electrical and mechanical specifications of BK-HKL-EX. However, the termination style differs: BK-HKL-EX uses Quick Connect termination while BK-HKL-X uses Solder Lug termination. Substitution is valid only if the circuit design can accommodate solder lug connection or if circuit modification is performed.

Q: What is the reason for BK-HKL-EX obsolescence?

A: BK-HKL-EX is classified as obsolete. BK-HKL-X is the active equivalent part from the same manufacturer and series, indicating product line consolidation or manufacturing transition.

Q: Are there packaging differences between BK-HKL-EX and BK-HKL-X?

A: BK-HKL-EX packaging is listed as unspecified. BK-HKL-X is supplied in Bulk packaging. Procurement quantities and handling procedures may differ accordingly.

Q: Do both parts meet the same compliance standards?

A: Both BK-HKL-EX and BK-HKL-X are RoHS non-compliant and carry identical ECCN and HTSUS classifications. Regulatory compliance status remains unchanged during substitution.

Q: What fuse types are compatible with these holders?

A: Both holders accommodate 3AG cartridge fuses with dimensions 0.25" diameter by 1.26" length (6.35mm x 32mm), designated as 1/4" x 1-1/4" (SFE-20).
