Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HLT-D are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitutability are:

• Current Rating: 15 A
• Voltage Rating: 125V
• Fuse Size: 0.689" L x 0.127" W x 0.81" H (17.5mm x 3.23mm x 20.57mm)
• Fuse Type: Indicating Fuse
• Fuseholder Type: Block
• Termination Style: PC Pin
• Contact Material: Copper
• Contact Finish: Tin

The substitute part BK/HLT-D matches all critical electrical and mechanical parameters, ensuring functional equivalence in circuit protection applications.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can BK/HLT-D be used as a direct replacement for HLT-D?

A: Yes. The BK/HLT-D is electrically and mechanically equivalent to the HLT-D. Both components have identical current ratings (15 A), voltage ratings (125V), fuse sizes, termination styles, and contact specifications. The BK/HLT-D is the active production equivalent of the obsolete HLT-D.

Q: What is the difference between HLT-D and BK/HLT-D?

A: The primary difference is product status. The HLT-D is obsolete, while the BK/HLT-D is active. The BK/HLT-D is also RoHS Compliant. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The HLT-D packaging is listed as standard, while the BK/HLT-D is supplied in bulk packaging. This does not affect functional compatibility or electrical performance.

Q: What are the critical parameters for substitution?

A: Substitution is determined by matching current rating (15 A), voltage rating (125V), fuse size (0.689" L x 0.127" W x 0.81" H), fuse type (Indicating Fuse), fuseholder type (Block), termination style (PC Pin), and contact specifications (Copper with Tin finish).

Q: Is the BK/HLT-D suitable for new designs?

A: Yes. The BK/HLT-D is an active product with RoHS Compliance, making it suitable for new circuit protection applications requiring 15 A, 125V indicating fuse block functionality.
