HTB-46I-R Equivalent & Substitute Parts Reference

Part Overview

The HTB-46I-R is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications in 250V circuits. This component is rated for 20A continuous current and accommodates 0.25" diameter x 1.26" length cartridge fuses (6.35mm x 32mm). The part is Active in product status and RoHS Compliant, with unlimited moisture sensitivity rating (MSL 1). Current inventory availability is 702 pieces in new original condition.

Equivalent and substitute parts are identified when operational requirements permit reduced current ratings or alternative termination configurations while maintaining core voltage, fuse type, and mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the HTB-46I-R is based on the following allowed parameters:

Voltage Compatibility: Substitute parts must maintain 250V rating to ensure safe operation in the intended circuit environment.

Fuse Type and Size: All substitutes must accept 0.25" diameter cartridge fuses to ensure mechanical and electrical compatibility with existing fuse inventory and circuit protection standards.

Mounting Configuration: Panel mount orientation is required to maintain installation compatibility with existing enclosure designs.

Circuit Count: Single-circuit configuration is maintained across all substitutes.

Current Rating Variance: The HTB-46I-R is rated for 20A. Substitute BK1-HTJ-606I is rated for 10A. This substitute is applicable only in applications where the circuit protection requirement is 10A or lower, or where the 10A rating provides appropriate protection for a lower-current branch of a larger system.

Regulatory Compliance: All substitutes must maintain RoHS Compliance status to satisfy environmental and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

HTB-46I-R Selection Criteria: Select the HTB-46I-R when the circuit requires 20A protection with Quick Connect termination. This part is Active in product status with RoHS Compliance certification. Current inventory of 702 pieces supports immediate procurement for standard applications.

BK1-HTJ-606I Selection Criteria: Select BK1-HTJ-606I only when circuit protection requirements are 10A or lower. This substitute differs in two parameters: current rating (10A versus 20A) and termination style (Solder Lug versus Quick Connect). The Solder Lug termination requires permanent connection methods rather than quick-disconnect capability. Both parts maintain 250V voltage rating, cartridge fuse type, panel mount configuration, and RoHS Compliance. Higher inventory availability (1700 pieces) may support extended production schedules.

Compliance Status: Both parts are Active in product status and RoHS Compliant, satisfying current regulatory requirements. ECCN classification is EAR99 for both parts.

Frequently Asked Questions (FAQ)

Q: Can BK1-HTJ-606I replace HTB-46I-R in all applications?

A: No. BK1-HTJ-606I is rated for 10A, while HTB-46I-R is rated for 20A. Substitution is valid only in circuits where 10A protection is appropriate. Additionally, termination style differs: HTB-46I-R uses Quick Connect, while BK1-HTJ-606I uses Solder Lug, requiring different installation methods.

Q: Are the fuse sizes compatible between these two holders?

A: Both holders accept 0.25" diameter cartridge fuses. HTB-46I-R specifies 0.25" Dia x 1.26" L (6.35mm x 32mm), while BK1-HTJ-606I specifies 0.250" Dia (6.35mm). The diameter is identical; length specifications are compatible with standard 1/4" cartridge fuses.

Q: What is the difference in termination style, and does it affect compatibility?

A: HTB-46I-R uses Quick Connect - 0.250" (6.3mm) termination, allowing rapid connection and disconnection. BK1-HTJ-606I uses Solder Lug termination, requiring permanent soldered connections. This difference affects installation method and is not interchangeable without circuit redesign.

Q: Are both parts RoHS Compliant?

A: Yes. Both HTB-46I-R and BK1-HTJ-606I are RoHS Compliant and suitable for applications requiring environmental compliance certification.

Q: Which part should I select for new designs?

A: Select based on circuit current requirements. For 20A circuits with quick-connect requirements, use HTB-46I-R. For 10A circuits with soldered connections, use BK1-HTJ-606I. Both are Active in product status and support long-term availability.

Q: Is inventory availability a factor in part selection?

A: Inventory levels may influence procurement timing. BK1-HTJ-606I has 1700 pieces available versus 702 pieces for HTB-46I-R. However, part selection must be based on electrical and mechanical requirements first, with inventory as a secondary consideration.
