Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/HTB-98-R is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters:

• Current Rating: 20 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Number of Circuits: 1 (exact match required)

Mechanical Parameters:

• Fuse Size: 0.25" Dia x 1.26" L (6.35mm x 32mm) (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Fuse Type: Cartridge (exact match required)
• Compatible Fuse Standard: 3AG, 1/4" x 1-1/4" (SFE-20) (exact match required)

Termination Compatibility:

• Termination Style: Quick Connect (functional equivalence acceptable with mechanical verification)

Substitute parts must satisfy all electrical and mechanical parameters listed above to ensure direct functional replacement without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The 03453HS1H manufactured by Littelfuse Inc. is an active equivalent substitute for the obsolete BK/HTB-98-R. Both components satisfy identical electrical ratings (20 A, 250V, single circuit) and mechanical specifications (cartridge fuse holder, panel mount, 3AG fuse compatibility).

Product Status Consideration: The BK/HTB-98-R is classified as obsolete. The 03453HS1H maintains active product status with Littelfuse, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Compliance and Certification: Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. The 03453HS1H provides additional compliance documentation including ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements.

Termination Consideration: The BK/HTB-98-R features 0.250" (6.3mm) Quick Connect termination, while the 03453HS1H features 0.187" (4.7mm) Quick Connect termination. Circuit board or wiring harness modifications may be required to accommodate the different termination pin diameter. Mechanical verification of connector compatibility with existing PCB or terminal block designs is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the 03453HS1H directly replace the BK/HTB-98-R without any modifications?

A: The 03453HS1H satisfies all electrical and mechanical parameters required for functional equivalence. However, the termination pin diameter differs (0.250" versus 0.187"), requiring verification that existing connector receptacles or PCB pads accommodate the smaller pin diameter of the Littelfuse component.

Q: Are the fuse cartridges interchangeable between these two holders?

A: Yes. Both holders accept identical 3AG cartridge fuses rated 1/4" x 1-1/4" (SFE-20). Fuse cartridge compatibility is not affected by the holder manufacturer.

Q: What is the significance of the different termination pin sizes?

A: The termination pin diameter determines the mechanical interface with the circuit board or terminal block. The BK/HTB-98-R uses 0.250" (6.3mm) pins, while the 03453HS1H uses 0.187" (4.7mm) pins. Existing receptacles designed for 0.250" pins will not properly accommodate 0.187" pins without modification or adapter components.

Q: Does the 03453HS1H provide better compliance documentation than the BK/HTB-98-R?

A: The 03453HS1H includes explicit ROHS3 compliance and REACH unaffected status certifications. The BK/HTB-98-R, being obsolete, may lack current compliance documentation. For applications requiring modern regulatory compliance, the 03453HS1H provides documented certification.

Q: Is the 03453HS1H available in the same packaging as the BK/HTB-98-R?

A: The 03453HS1H is supplied in bulk packaging. Original packaging specifications for the BK/HTB-98-R are not provided in the available data. Packaging requirements should be confirmed with procurement specifications.

Q: What is the inventory status of these components?

A: The BK/HTB-98-R has 767 pieces in stock as new original inventory. The 03453HS1H has 1144 pieces in stock as new original inventory. Inventory levels are subject to change and should be confirmed at time of procurement.
