Equivalent & Substitute Parts for BK/HTB-62M

Part Overview

The BK/HTB-62M is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for 16 A at 250V operation in panel mount applications. This component accommodates 5mm x 20mm cartridge fuses with quick connect termination. The BK/HTB-62M carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/HTB-62M is determined by the following critical parameters:

Direct Equivalency Criteria:

• Fuse size: 5mm x 20mm cartridge format
• Voltage rating: 250V minimum
• Mounting configuration: Panel mount
• Termination interface: Quick connect 0.187" (4.7mm)
• Number of circuits: Single circuit (1)

Current Rating Considerations:

• Direct equivalent: 16 A current rating
• Similar substitute: 10 A current rating (lower capacity, same form factor and interface)

The BK/HTB-62M-R qualifies as a direct equivalent, maintaining identical electrical and mechanical specifications while offering active product status. The Littelfuse 03455RF2H functions as a similar substitute with compatible mechanical and electrical interfaces, though with a reduced current rating of 10 A.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The BK/HTB-62M-R is the primary substitute for the obsolete BK/HTB-62M. Both components share identical electrical specifications (16 A, 250V), mechanical form factor (5mm x 20mm cartridge), and termination interface (quick connect 0.187"). The BK/HTB-62M-R carries active product status and ROHS3 compliance, addressing regulatory requirements that the original part does not meet.

For Alternative Applications: The Littelfuse 03455RF2H provides mechanical and electrical compatibility within the same fuse holder category. This part maintains the same voltage rating (250V), fuse size (5mm x 20mm), mounting configuration (panel mount), and termination style (quick connect 0.187"). The current rating difference (10 A versus 16 A) restricts its use to circuits designed for 10 A operation or lower. The 03455RF2H offers ROHS3 compliance and active product status.

Compliance Considerations: Both substitute parts achieve ROHS3 compliance, whereas the original BK/HTB-62M is RoHS non-compliant. Selection should account for system-level regulatory requirements and environmental standards applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the BK/HTB-62M-R be used as a direct replacement for the BK/HTB-62M? A: Yes. The BK/HTB-62M-R maintains identical current rating (16 A), voltage rating (250V), fuse size (5mm x 20mm), mounting type (panel mount), and termination interface (quick connect 0.187"). Both are single-circuit cartridge fuse holders. The primary difference is product status: BK/HTB-62M-R is active while BK/HTB-62M is obsolete.

Q: What is the key difference between the BK/HTB-62M-R and the Littelfuse 03455RF2H? A: The primary difference is current rating. The BK/HTB-62M-R is rated for 16 A, while the 03455RF2H is rated for 10 A. All other parameters—voltage (250V), fuse size (5mm x 20mm), mounting (panel mount), and termination (quick connect 0.187")—are identical. The 03455RF2H is suitable only for circuits designed for 10 A operation.

Q: Are there packaging differences between these parts? A: The BK/HTB-62M-R is supplied in bulk packaging. The Littelfuse 03455RF2H is also supplied in bulk packaging. Packaging specifications should be confirmed with the supplier for specific procurement requirements.

Q: Do all three parts support the same fuse cartridge size? A: Yes. All three parts—BK/HTB-62M, BK/HTB-62M-R, and 03455RF2H—accommodate 5mm x 20mm cartridge fuses and use identical quick connect termination (0.187" / 4.7mm).

Q: What is the significance of RoHS compliance in selecting a substitute? A: The BK/HTB-62M is RoHS non-compliant, while both BK/HTB-62M-R and 03455RF2H are ROHS3 compliant. If the application or end market requires RoHS compliance, either substitute part satisfies this requirement. The original part does not.

Q: Can the 03455RF2H be used in a 16 A circuit? A: No. The 03455RF2H is rated for 10 A maximum. Using it in a 16 A circuit exceeds its current rating and violates electrical safety standards. The BK/HTB-62M-R must be used for 16 A applications.
