HLS-F Fuse Block Equivalent & Substitute Parts

Part Overview

The HLS-F is a through-hole fuse block manufactured by Eaton - Bussmann Electrical Division, rated for 15A at 125VAC/60VDC. This component serves as a circuit protection and indication device for PCB applications. The part is currently in active production status with 965 units in stock. Substitute parts are identified when electrical ratings, mechanical dimensions, mounting characteristics, and compliance certifications remain equivalent across the allowed parameter set.

Substitute Part Grouping Explanation

The HLS-F and BK/HLS-F are classified as direct substitutes based on equivalence across all critical electrical and mechanical parameters. Substitution is valid when the following conditions are met:

• Current rating matches exactly at 15A
• Voltage rating matches exactly at 125VAC and 60VDC
• Physical dimensions are identical: 0.689" L x 0.127" W x 0.81" H
• Mounting type is through-hole with vertical orientation
• Termination style is PC pin
• Fuse type is indicating fuse with block fuseholder type
• Contact material and finish are copper with tin plating

Both parts satisfy these criteria and are therefore electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both HLS-F and BK/HLS-F are active production parts from Eaton - Bussmann Electrical Division with full RoHS compliance. The BK/HLS-F carries ROHS3 compliance designation and REACH Unaffected status, providing additional regulatory documentation. Both parts share identical electrical ratings, mechanical dimensions, and termination characteristics. Selection between these parts may be based on inventory availability: HLS-F has 965 units in stock, while BK/HLS-F has 1803 units in stock. Both are suitable for direct substitution in 15A, 125VAC/60VDC through-hole PCB fuse block applications.

Frequently Asked Questions (FAQ)

Q: Can BK/HLS-F replace HLS-F in existing designs? A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including current rating, voltage rating, physical dimensions, mounting type, and termination style.

Q: Are there differences in compliance certifications? A: Both parts are RoHS compliant. BK/HLS-F additionally carries ROHS3 compliance and REACH Unaffected designation. Both carry identical ECCN and HTSUS classifications.

Q: What determines substitutability for this fuse block category? A: Substitutability is determined by matching current rating (15A), voltage rating (125VAC/60VDC), physical dimensions (0.689" L x 0.127" W x 0.81" H), mounting type (through-hole), orientation (vertical), termination style (PC pin), and contact specifications (copper with tin finish).

Q: Are there inventory considerations for part selection? A: HLS-F has 965 units available, while BK/HLS-F has 1803 units available. Both are in active production and suitable for immediate use.

Q: Do these parts require different PCB footprints? A: No. Both parts have identical physical dimensions and PC pin termination, requiring the same PCB footprint and mounting hole pattern.
