Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HTB-44M-R are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent (BK/HTB-44M-R): This part maintains identical specifications across all critical parameters: 16 A current rating, 250V voltage, 5mm x 20mm fuse size, single circuit, panel mount configuration, and quick connect termination. The only variance is enhanced RoHS3 compliance status and REACH Unaffected designation. This part is a direct functional equivalent suitable for one-to-one replacement.

Similar Substitute (BK2-HTC-623M): This part shares the same fuse size (5mm diameter), voltage rating (250V), mounting type (panel mount), and single-circuit configuration. However, it differs in current rating (10 A versus 16 A), termination style (solder lug versus quick connect), and contact material specifications (brass with nickel finish). This part is classified as a similar substitute only when current rating reduction is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: BK/HTB-44M-R is the primary equivalent substitute. It maintains all electrical and mechanical specifications of the HTB-44M-R while offering enhanced ROHS3 compliance and REACH Unaffected status. Both parts are Active in product status and suitable for immediate substitution in existing designs and applications.

For Current-Reduced Applications: BK2-HTC-623M may be selected only when the application circuit requires a maximum 10 A current rating instead of 16 A. This part maintains voltage, fuse size, mounting configuration, and single-circuit design but requires solder lug termination instead of quick connect. Selection of this part necessitates verification that the 10 A rating satisfies circuit protection requirements and that solder lug termination is compatible with the PCB or panel layout.

All three parts are manufactured by Eaton - Electronics Division, carry Active product status, and meet RoHS compliance requirements, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-44M-R be used as a direct replacement for HTB-44M-R?

A: Yes. BK/HTB-44M-R is a direct equivalent with identical electrical and mechanical specifications: 16 A current rating, 250V voltage, 5mm x 20mm fuse size, single circuit, panel mount, and quick connect termination. The part offers enhanced ROHS3 compliance and REACH Unaffected status.

Q: What are the key differences between HTB-44M-R and BK2-HTC-623M?

A: The primary differences are current rating (16 A versus 10 A) and termination style (quick connect versus solder lug). BK2-HTC-623M also specifies brass contact material with nickel finish. Both parts share 250V voltage, 5mm fuse diameter, panel mount configuration, and single-circuit design.

Q: When should BK2-HTC-623M be selected instead of the direct equivalent?

A: BK2-HTC-623M should be selected only when the application circuit requires a maximum 10 A current rating and solder lug termination is compatible with the installation method. This part is not suitable for applications requiring 16 A protection.

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

A: HTB-44M-R and BK/HTB-44M-R are fully compatible with 5mm x 20mm cartridge fuses. BK2-HTC-623M accommodates 5mm diameter fuses but does not specify the 20mm length requirement in its detailed parameters.

Q: What is the inventory status for each part?

A: HTB-44M-R has 841 pieces in stock. BK/HTB-44M-R has 1943 pieces in stock. BK2-HTC-623M has 2571 pieces in stock. All parts are listed as New Original.

Q: Do all parts meet RoHS compliance?

A: Yes. HTB-44M-R and BK2-HTC-623M are RoHS Compliant. BK/HTB-44M-R is ROHS3 Compliant, which represents an enhanced compliance level. All parts have MSL Rating 1 (Unlimited).
