Eaton HTB-32M-R Fuse Holder Equivalent & Substitute Parts

Part Overview

The HTB-32M-R is a cartridge fuse holder manufactured by Eaton - Electronics Division, rated for 16 A at 250V with panel mount configuration. This component is designed for single-circuit applications using 5mm x 20mm cartridge fuses with quick connect termination. The part maintains Active product status and is RoHS Compliant.

Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional specifications align with the main part's design parameters, enabling direct replacement in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical parameter alignment:

Direct Equivalent (BK/HTB-32M-R): This substitute maintains identical electrical specifications (16 A, 250V), mechanical dimensions (5mm x 20mm), circuit count (1), mounting configuration (panel mount), and termination style (quick connect). The part is from the same HTB series and carries ROHS3 Compliant status with REACH Unaffected designation.

Similar Substitutes (BK2-HTC-607M, BK2-HTC-609M): These parts share common electrical voltage (250V), fuse type (cartridge), circuit count (1), and mounting configuration (panel mount). However, they differ in current rating (10 A versus 16 A), fuse size specification (5mm diameter only versus 5mm x 20mm), series designation (HTC versus HTB), and termination style (solder lug versus quick connect). These parts are suitable only when circuit protection requirements specify 10 A maximum current and solder lug termination is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The BK/HTB-32M-R provides full electrical and mechanical compatibility with the HTB-32M-R. Both parts maintain Active product status, identical current and voltage ratings, matching fuse dimensions, and quick connect termination. The BK/HTB-32M-R carries ROHS3 Compliant certification with REACH Unaffected status, representing an enhanced compliance profile suitable for applications requiring current regulatory standards.

For Current-Limited Applications: The BK2-HTC-607M and BK2-HTC-609M are suitable only when circuit protection requirements specify maximum 10 A current rating. These parts require solder lug termination instead of quick connect, necessitating circuit board redesign or adapter implementation. The 5mm diameter specification differs from the 5mm x 20mm cartridge format of the main part. Both similar substitutes maintain Active product status and RoHS Compliance with REACH Unaffected designation.

Compliance Considerations: All substitute parts maintain Active product status and comply with RoHS regulations. The direct equivalent BK/HTB-32M-R provides enhanced ROHS3 compliance. All parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, confirming regulatory alignment for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-32M-R replace HTB-32M-R in existing designs without modification?

A: Yes. The BK/HTB-32M-R maintains identical electrical ratings (16 A, 250V), fuse dimensions (5mm x 20mm), circuit count (1), mounting configuration (panel mount), and termination style (quick connect 0.187"). No circuit modifications are required.

Q: What is the primary difference between HTB-32M-R and the HTC series substitutes?

A: The HTB-32M-R is rated for 16 A with quick connect termination, while BK2-HTC-607M and BK2-HTC-609M are rated for 10 A with solder lug termination. The HTC series also specifies 5mm diameter fuses without length specification, whereas the HTB series uses 5mm x 20mm cartridges. These differences prevent direct substitution without circuit redesign.

Q: Are the similar substitutes (BK2-HTC-607M and BK2-HTC-609M) interchangeable with each other?

A: Yes, for applications requiring 10 A protection at 250V with solder lug termination and panel mount configuration. Both parts share identical electrical specifications, fuse type, circuit count, and mounting characteristics. Inventory availability may determine selection between these two options.

Q: What compliance certifications apply to all substitute parts?

A: All parts maintain RoHS Compliance status with MSL Rating 1 (Unlimited moisture sensitivity). The direct equivalent BK/HTB-32M-R carries enhanced ROHS3 Compliant certification. All parts are REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8538.90.8180.

Q: Can the 10 A rated HTC series parts protect circuits designed for 16 A operation?

A: No. The BK2-HTC-607M and BK2-HTC-609M are rated for maximum 10 A continuous current. Using these parts in 16 A circuits would result in nuisance tripping and inadequate circuit protection. Current rating must match or exceed the protected circuit's maximum operating current.

Q: What termination differences exist between the main part and similar substitutes?

A: The HTB-32M-R uses quick connect termination (0.187" / 4.7mm), enabling tool-free connection to standard quick connect receptacles. The BK2-HTC-607M and BK2-HTC-609M use solder lug termination, requiring direct soldering to circuit board traces or wire connections. Termination style selection depends on circuit board design and assembly process requirements.
