BK/HTB-22I Cartridge Fuse Holder Equivalent & Substitute Parts

Part Overview

The BK/HTB-22I is a panel-mounted cartridge fuse holder manufactured by Eaton - Electronics Division, rated for 20 A at 250V with single-circuit configuration. This component is classified as Active product status and is designed for use with 3AG and 1/4" x 1-1/4" (SFE-20) cartridge fuses. Alternative part numbers are identified to address packaging preferences, compliance requirements, and current rating variations in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/HTB-22I are identified based on the following criteria:

Direct Substitutes (Identical Electrical & Mechanical Parameters): Parts that maintain all critical parameters including current rating (20 A), voltage (250V), fuse size (0.25" Dia x 1.26" L), mounting type (Panel Mount), number of circuits (1), and fuse type (Cartridge). Differences in packaging format (Bulk vs. Box) and RoHS compliance status do not affect functional equivalence.

Similar Substitutes (Partial Parameter Alignment): Parts that share core mechanical compatibility (panel mount, cartridge fuse type, 250V voltage, single circuit) but differ in current rating or termination style. These require engineering evaluation for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

BK/HTB-22I-R (Direct Substitute): This part is electrically and mechanically identical to the BK/HTB-22I, with identical current rating (20 A), voltage (250V), fuse size, mounting configuration, and termination style. The primary distinction is packaging format (Box vs. Bulk) and RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant). Selection of BK/HTB-22I-R is appropriate when ROHS3 compliance is required or when box packaging is preferred for inventory management. Higher stock availability (5840 Pcs) supports procurement planning.

BK16-HTJ-601I (Similar Substitute): This part shares mechanical compatibility as a panel-mounted, single-circuit cartridge fuse holder rated at 250V. However, the current rating is 10 A, which is 50% lower than the BK/HTB-22I. The termination style differs (Solder Lug vs. Quick Connect). This part is suitable only for circuits requiring 10 A protection and where solder-lug termination is compatible with the application. RoHS compliance status is Compliant. Selection requires confirmation that the lower current rating and different termination method meet circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-22I-R be used as a direct replacement for BK/HTB-22I?

A: Yes. BK/HTB-22I-R is a direct electrical and mechanical equivalent. Both parts are rated 20 A at 250V, accept the same 0.25" Dia x 1.26" L cartridge fuses, feature identical Quick Connect termination, and are configured for single-circuit panel mounting. Packaging format and RoHS compliance differ but do not affect functional performance.

Q: What are the limitations of BK16-HTJ-601I as a substitute?

A: BK16-HTJ-601I has a 10 A current rating, which is lower than the BK/HTB-22I (20 A). Additionally, termination style is Solder Lug rather than Quick Connect. This part is suitable only for applications requiring 10 A protection with solder-lug connection capability. Fuse size specification for BK16-HTJ-601I lists 0.250" Dia without length specification, indicating potential dimensional variation.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance status is a regulatory and procurement consideration but does not affect electrical or mechanical performance. BK/HTB-22I-R (ROHS3 Compliant) is preferred for applications subject to RoHS regulations. BK/HTB-22I (RoHS non-compliant) and BK16-HTJ-601I (RoHS Compliant) require evaluation based on end-use regulatory requirements.

Q: Are all substitute parts rated for the same voltage?

A: Yes. BK/HTB-22I, BK/HTB-22I-R, and BK16-HTJ-601I are all rated 250V. Voltage compatibility is maintained across all listed substitutes.

Q: What is the difference between Quick Connect and Solder Lug termination?

A: Quick Connect termination (0.187" / 4.7mm) uses a push-on connector interface for rapid assembly without soldering. Solder Lug termination requires permanent solder connection to circuit board traces or wiring. Selection depends on assembly method and application requirements.

Q: Can fuse size differences affect substitution?

A: Yes. BK/HTB-22I and BK/HTB-22I-R both accept 0.25" Dia x 1.26" L cartridge fuses. BK16-HTJ-601I specifies 0.250" Dia without complete length specification, indicating potential incompatibility with standard 1.26" L fuses. Fuse compatibility must be verified before substitution.
