Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for cartridge fuse holders is determined by electrical and mechanical compatibility across the following parameters:

Critical Parameters for Substitution:

• Current Rating (Amps)
• Voltage Rating (V)
• Fuse Size (Dia x L)
• Mounting Type
• Number of Circuits
• Termination Style

Direct Equivalent: BK/HTB-32M-R maintains identical electrical and mechanical specifications to the main part, differing only in product status (Active vs. Obsolete) and RoHS compliance level.

Similar Substitute: 03455LS2H (Littelfuse Inc.) shares mechanical compatibility (5mm x 20mm fuse size, panel mount, quick connect termination, 250V rating, single circuit) but operates at a reduced current rating of 10 A versus the original 16 A specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): BK/HTB-32M-R is the primary substitute for the obsolete BK/HTB-32M. Both components share identical electrical ratings (16 A, 250V), mechanical dimensions (5mm x 20mm), and functional characteristics. BK/HTB-32M-R is currently in active production status with significantly higher inventory availability (3239 Pcs vs. 902 Pcs). Additionally, BK/HTB-32M-R meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant.

For Current-Limited Applications: 03455LS2H (Littelfuse Inc.) is a mechanically compatible alternative when circuit protection requirements permit operation at 10 A instead of 16 A. This substitute maintains identical mechanical form factor, voltage rating (250V), fuse size (5mm x 20mm), mounting configuration (panel mount), and termination style (quick connect). The 03455LS2H is ROHS3 compliant and currently active in production.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-32M-R be used as a direct replacement for BK/HTB-32M? A: Yes. BK/HTB-32M-R is electrically and mechanically identical to BK/HTB-32M, with matching current rating (16 A), voltage (250V), fuse size (5mm x 20mm), and termination style (quick connect 0.187"). The primary differences are product status (Active vs. Obsolete) and RoHS compliance level.

Q: What is the key limitation of using 03455LS2H as a substitute? A: The 03455LS2H operates at 10 A maximum current rating, compared to the original 16 A specification. This substitute is suitable only for applications where the circuit current requirement does not exceed 10 A. Mechanical compatibility (fuse size, mounting, termination) is maintained.

Q: Are all substitute parts mechanically interchangeable? A: Yes. Both BK/HTB-32M-R and 03455LS2H share identical mechanical specifications: 5mm x 20mm fuse size, panel mount configuration, single-circuit design, and quick connect 0.187" termination style. Physical installation is identical.

Q: What is the voltage compatibility across all parts? A: All three parts (BK/HTB-32M, BK/HTB-32M-R, and 03455LS2H) are rated for 250V operation. Voltage compatibility is maintained across all substitutes.

Q: Which substitute offers the best compliance profile? A: Both BK/HTB-32M-R and 03455LS2H are ROHS3 compliant and REACH unaffected. The original BK/HTB-32M is RoHS non-compliant. For applications requiring modern compliance standards, either active substitute is appropriate.

Q: How do termination styles compare? A: All three parts use identical quick connect termination: 0.187" (4.7mm). Electrical connection methodology is consistent across the main part and all substitutes.
