HLS-01-SL Equivalent & Substitute Parts

Part Overview

The HLS-01-SL is a fuse block assembly manufactured by Eaton - Bussmann Electrical Division, designed for blade fuse applications in 125VAC/60VDC circuits. This through-hole mounted component provides single-circuit fuse protection with integrated indicating functionality for GMT-series fuses. The part maintains Active product status and is RoHS Compliant, making it suitable for current production applications requiring PCB-mounted fuse management.

Substitute parts are identified when electrical ratings, mechanical dimensions, mounting characteristics, and functional specifications remain identical across the product line, ensuring direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLS-01-SL is determined by strict equivalence across the following critical parameters:

• Electrical Ratings: Current rating of 15 A and voltage rating of 125VAC/60VDC
• Mechanical Dimensions: Fuse size of 0.689" L x 0.127" W x 0.81" H
• Circuit Configuration: Single-circuit design
• Mounting and Termination: Through-hole mounting with vertical orientation and PC pin termination
• Contact Specifications: Copper material with tin finish
• Functional Type: Indicating fuse block configuration

The substitute part BK/HLS-01-SL meets all these criteria, maintaining identical electrical performance and mechanical compatibility while differing only in manufacturer designation and compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both HLS-01-SL and BK/HLS-01-SL are Active products from Eaton - Bussmann Electrical Division with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Compliance Requirements: BK/HLS-01-SL carries ROHS3 Compliant certification, while HLS-01-SL is RoHS Compliant. Applications requiring ROHS3 compliance should specify BK/HLS-01-SL.
• Availability: Both parts are in stock. HLS-01-SL has 852 pieces available; BK/HLS-01-SL has 3177 pieces available.
• Regulatory Status: BK/HLS-01-SL includes REACH Unaffected designation, providing additional regulatory clarity for European applications.

Both parts are suitable for direct substitution in 15 A, 125VAC/60VDC single-circuit fuse block applications with through-hole PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can BK/HLS-01-SL replace HLS-01-SL in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (15 A), voltage ratings (125VAC/60VDC), fuse dimensions, mounting type (through-hole), and termination style (PC pin). Direct substitution is possible without circuit modification.

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

A: ROHS3 Compliant represents the current RoHS 3 directive standard (2011/65/EU as amended), while RoHS Compliant refers to the earlier RoHS directive. ROHS3 Compliant parts meet more recent regulatory requirements and are preferred for new designs targeting European markets.

Q: Are the fuse sizes identical between these parts?

A: Yes. Both HLS-01-SL and BK/HLS-01-SL accommodate fuses of 0.689" L x 0.127" W x 0.81" H (17.5mm x 3.23mm x 20.57mm), ensuring mechanical compatibility with GMT Indicating fuses.

Q: What mounting orientation do these fuse blocks support?

A: Both parts are mounted vertically through PCB holes using PC pin termination with copper contacts finished in tin. This configuration is standard for single-circuit blade fuse blocks in this current and voltage class.

Q: Which part should be selected for new production?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance or REACH compliance documentation, specify BK/HLS-01-SL. For applications with standard RoHS requirements, either part is acceptable based on availability and supply chain considerations.
