HTB-58I-R Equivalent & Substitute Parts Reference

Part Overview

The HTB-58I-R is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications in 250V circuits with a 20A current rating. This component is classified as Active product status and is RoHS Compliant. The HTB-58I-R accommodates 3AG cartridge fuses with dimensions of 0.25" Dia x 1.26" L (6.35mm x 32mm). Substitute parts are identified when packaging configurations differ or when alternative compliance certifications are required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HTB-58I-R is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Current rating (20 A), voltage rating (250V), and number of circuits (1) must be identical.

Mechanical Parameters: Fuse size (0.25" Dia x 1.26" L), mounting type (Panel Mount), and termination style (Quick Connect - 0.250") must match exactly.

Functional Parameters: Fuse type (Cartridge) and compatibility with 3AG/SFE-20 fuse standards must be maintained.

Compliance Parameters: RoHS compliance status and product status (Active) are required for direct substitution.

The identified substitute part BK/HTB-58I-R differs only in packaging configuration (Bag versus Bulk) and secondary compliance certifications (ROHS3 Compliant and REACH Unaffected status), while maintaining complete electrical and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both HTB-58I-R and BK/HTB-58I-R are Active status products manufactured by Eaton - Electronics Division with full RoHS compliance. Selection between these parts is determined by packaging and procurement requirements rather than electrical or mechanical performance.

HTB-58I-R (Bulk Packaging): Select this configuration for high-volume applications or when bulk packaging aligns with supply chain logistics. This part carries standard RoHS Compliant certification with 1045 units currently in stock.

BK/HTB-58I-R (Bag Packaging): Select this configuration when bag packaging is required for inventory management, kit assembly, or distribution protocols. This part carries ROHS3 Compliant certification and REACH Unaffected status with 938 units currently in stock.

Both parts are electrically and mechanically identical for 250V, 20A single-circuit cartridge fuse holder applications with panel mount configuration and Quick Connect termination.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-58I-R replace HTB-58I-R in a 250V, 20A panel mount circuit?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current rating (20 A), voltage rating (250V), fuse size (0.25" Dia x 1.26" L), mounting type (Panel Mount), termination style (Quick Connect - 0.250"), and compatibility with 3AG/SFE-20 cartridge fuses. The difference is packaging only (Bulk versus Bag).

Q: What is the difference between RoHS Compliant and ROHS3 Compliant certifications?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more recent certification iteration. Both parts meet RoHS requirements and are suitable for equivalent applications.

Q: Are these fuse holders compatible with standard 3AG fuses?

A: Yes. Both HTB-58I-R and BK/HTB-58I-R are designed for use with 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (SFE-20 standard).

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection depends on packaging requirements and supply chain preferences. Both are Active status products with full compliance certifications.

Q: Can these parts be used in circuits exceeding 20A?

A: No. Both parts are rated for maximum 20A continuous current. Use only in circuits matching or below this specification.
