BK/HTB-36M Fuse Holder Cartridge 250V 16A Panel Mount

Part Overview

The BK/HTB-36M is a cartridge fuse holder rated for 16 A at 250V with panel mount configuration, designed for 5mm x 20mm cartridge fuses. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing system maintenance and new designs. The obsolete status of the BK/HTB-36M requires engineers to evaluate active alternative products that maintain electrical and mechanical compatibility with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/HTB-36M are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Parameters:

• Fuse Size: 5mm x 20mm cartridge format
• Voltage Rating: 250V minimum
• Mounting Type: Panel Mount
• Termination Style: Quick Connect - 0.250" (6.3mm)
• Number of Circuits: 1
• Fuseholder Type: Holder

Current Rating Consideration: The BK/HTB-36M-R maintains identical current rating (16 A), providing direct equivalence. The 03455LS8H operates at 10 A, which represents a lower current capacity and is classified as a similar substitute rather than a direct equivalent.

Product Status Consideration: The BK/HTB-36M is obsolete. The BK/HTB-36M-R is the active equivalent from the same manufacturer series (HTB). The 03455LS8H is an active alternative from a different manufacturer (Littelfuse Inc., Series 345).

Parameter Comparison

Engineering Selection Recommendations

BK/HTB-36M-R (Direct Equivalent): The BK/HTB-36M-R is the primary substitute for the obsolete BK/HTB-36M. Both components share identical electrical ratings (16 A, 250V), mechanical dimensions (5mm x 20mm cartridge), and termination specifications. The BK/HTB-36M-R is manufactured by the same company (Eaton - Electronics Division) within the same HTB series. The BK/HTB-36M-R holds active product status and is ROHS3 compliant, addressing regulatory requirements that the original part does not meet. This part is recommended for direct replacement in all applications where the BK/HTB-36M was originally specified.

03455LS8H (Similar Substitute): The 03455LS8H is an alternative from Littelfuse Inc. that maintains mechanical and voltage compatibility (250V, 5mm x 20mm cartridge, panel mount, quick connect termination). However, the current rating is 10 A, which is lower than the original 16 A specification. The 03455LS8H is ROHS3 compliant and holds active product status. This part is suitable only for applications where the circuit current requirement does not exceed 10 A. The 03455LS8H provides an alternative source from a different manufacturer when supply constraints exist for the BK/HTB-36M-R.

Frequently Asked Questions (FAQ)

Q: Can the BK/HTB-36M-R be used as a direct replacement for the BK/HTB-36M?

A: Yes. The BK/HTB-36M-R is a direct equivalent. Both parts have identical current rating (16 A), voltage rating (250V), fuse size (5mm x 20mm), mounting type (panel mount), and termination style (quick connect 0.250"). The BK/HTB-36M-R is the active production version of the same HTB series from Eaton - Electronics Division.

Q: What is the key difference between the BK/HTB-36M-R and the 03455LS8H?

A: The primary difference is current rating. The BK/HTB-36M-R is rated for 16 A, while the 03455LS8H is rated for 10 A. Both maintain the same voltage (250V), fuse size (5mm x 20mm), and termination specifications. The 03455LS8H is manufactured by Littelfuse Inc. rather than Eaton.

Q: Can the 03455LS8H be used in a circuit designed for 16 A operation?

A: No. The 03455LS8H is rated for maximum 10 A. Using this part in a 16 A circuit would exceed its current rating and create a safety hazard. The 03455LS8H is suitable only for circuits with current requirements of 10 A or less.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The BK/HTB-36M is RoHS non-compliant. Both the BK/HTB-36M-R and 03455LS8H are ROHS3 compliant. For applications requiring RoHS compliance, either the BK/HTB-36M-R or 03455LS8H must be used instead of the original BK/HTB-36M.

Q: What packaging options are available for these fuse holders?

A: The BK/HTB-36M-R is supplied in Box packaging. The 03455LS8H is supplied in Bulk packaging. Packaging selection depends on order quantity requirements and inventory management practices.

Q: Are all three parts compatible with 5mm x 20mm cartridge fuses?

A: Yes. The BK/HTB-36M, BK/HTB-36M-R, and 03455LS8H all accept 5mm x 20mm cartridge fuses. All three parts use identical quick connect termination (0.250" / 6.3mm) and are rated for 250V operation.
