Equivalent & Substitute Parts for HTB-22M-R

Part Overview

The HTB-22M-R is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for 16 A at 250V operation in single-circuit panel mount applications. This component accommodates 5mm x 20mm cartridge fuses with quick connect termination. The part is Active status and RoHS Compliant, making it suitable for modern electronic equipment requiring reliable overcurrent protection integration.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, ensuring functional interchangeability within the defined operating envelope.

Key Parameters

Substitute Part Grouping Explanation

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

Direct Equivalent (BK/HTB-22M-R): This part maintains identical electrical specifications (16 A, 250V, 5mm x 20mm cartridge, single circuit) and mechanical configuration (panel mount, quick connect termination). The primary difference is RoHS compliance designation (ROHS3 Compliant versus RoHS Compliant) and inventory source. Both parts are manufactured by Eaton - Electronics Division within the HTB series and are Active status products.

Similar Substitute (BK8-HTC-603M): This part shares the same voltage rating (250V), fuse type (cartridge), mounting method (panel mount), and circuit count (1). However, it differs in current rating (10 A versus 16 A), fuse size specification (5mm diameter only, not 5mm x 20mm length), termination style (solder lug versus quick connect), and series designation (HTC versus HTB). This part is suitable only when 10 A protection is acceptable and solder termination is compatible with the application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: BK/HTB-22M-R is the appropriate choice when HTB-22M-R is unavailable. Both parts are Active status products from Eaton - Electronics Division with identical electrical and mechanical specifications. The ROHS3 Compliant designation of BK/HTB-22M-R represents an updated compliance standard and does not affect functional compatibility. This substitution maintains full parameter equivalence.

For Similar Substitution: BK8-HTC-603M is applicable only in applications where the current requirement is 10 A or less and solder termination is compatible with the circuit design. The reduced current rating and different termination method represent functional limitations that must be evaluated against specific application requirements. This part is not suitable as a direct replacement for 16 A quick-connect applications.

Compliance Considerations: All three parts maintain RoHS compliance status and are manufactured by Eaton - Electronics Division. Selection should prioritize Active status products to ensure continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-22M-R replace HTB-22M-R in all applications?

A: Yes. BK/HTB-22M-R maintains identical current rating (16 A), voltage rating (250V), fuse size (5mm x 20mm), mounting type (panel mount), and termination style (quick connect - 0.187"). Both are Active status products manufactured by Eaton - Electronics Division. The ROHS3 Compliant designation represents updated regulatory compliance and does not affect electrical or mechanical compatibility.

Q: What are the limitations of BK8-HTC-603M as a substitute?

A: BK8-HTC-603M has a reduced current rating of 10 A compared to the 16 A requirement of HTB-22M-R. Additionally, it uses solder lug termination instead of quick connect termination, and the fuse size specification is 5mm diameter only rather than 5mm x 20mm. This part is suitable only for applications requiring 10 A protection with solder-based circuit connections.

Q: Are all substitute parts from the same manufacturer?

A: Yes. HTB-22M-R, BK/HTB-22M-R, and BK8-HTC-603M are all manufactured by Eaton - Electronics Division. This ensures consistent quality standards and design philosophy across the product line.

Q: What is the significance of the fuse size difference between HTB-22M-R and BK8-HTC-603M?

A: HTB-22M-R accommodates 5mm x 20mm cartridge fuses, while BK8-HTC-603M is specified for 5mm diameter fuses. The length specification (20mm) is critical for proper cartridge seating and electrical contact. These are not interchangeable fuse holder designs.

Q: How do termination styles affect circuit integration?

A: HTB-22M-R uses quick connect termination (0.187" / 4.7mm), which connects to standard quick-connect terminals on PCBs or wiring harnesses. BK8-HTC-603M uses solder lug termination, requiring direct solder connections to circuit traces or wire leads. The termination method must match the circuit design and cannot be changed without component modification.

Q: Are there orientation differences between these parts?

A: HTB-22M-R and BK/HTB-22M-R do not specify orientation constraints. BK8-HTC-603M is rated for both horizontal and vertical orientation, providing additional installation flexibility. This does not affect substitution compatibility when orientation requirements are met.
