Substitute Part Grouping Explanation

Substitute parts for the KLM-1/10 are qualified based on strict alignment of the following electrical and mechanical parameters:

• Current Rating: 100mA (exact match required)
• Voltage Rating: 600 VAC and 600 VDC (both required)
• Response Time: Fast Blow (exact match required)
• Fuse Type: Cartridge (exact match required)
• Physical Dimensions: 0.406" Dia x 1.500" L (10.30mm x 38.10mm) (exact match required)
• Breaking Capacity: 100kA AC, 50kA DC (exact match required)
• Mounting Configuration: Requires Holder (exact match required)

The identified substitutes KLKD.100HXR and KLKD.100T, both manufactured by Littelfuse Inc., meet all specified electrical and mechanical criteria, enabling functional equivalence in holder-based installations.

Engineering Selection Recommendations

All three parts maintain Active product status and carry relevant regulatory approvals. The KLM-1/10 holds CE, CSA, and UL certifications. KLKD.100HXR carries CE and UL certifications, while KLKD.100T carries CE, CSA, and UL certifications, matching the original part's approval scope. All parts are RoHS compliant. Selection between the KLM-1/10 and its substitutes should be based on application-specific certification requirements and holder compatibility verification. KLKD.100T provides the most direct certification alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can KLKD.100HXR and KLKD.100T be used interchangeably with KLM-1/10?

A: Both Littelfuse parts meet the electrical and mechanical specifications of the KLM-1/10. Interchangeability depends on holder compatibility and certification requirements for your specific application. KLKD.100T carries CSA certification matching the original part.

Q: What is the difference between KLKD.100HXR and KLKD.100T?

A: Both parts share identical electrical ratings, dimensions, and breaking capacity. The primary difference is packaging: KLKD.100HXR is supplied in Bulk packaging, while KLKD.100T is supplied in Box packaging. KLKD.100T includes CSA certification, while KLKD.100HXR does not.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts measure 0.406" Dia x 1.500" L (approximately 10.30-10.31mm x 38.10mm), ensuring mechanical compatibility in standard 5AG/10mm x 38mm (Midget) holder assemblies.

Q: Do all parts meet the same regulatory standards?

A: The KLM-1/10 and KLKD.100T both carry CE, CSA, and UL certifications. KLKD.100HXR carries CE and UL certifications only. Application requirements should determine which certification scope is necessary.

Q: What is the breaking capacity specification?

A: All three parts are rated for 100kA AC and 50kA DC breaking capacity at their rated voltage, ensuring equivalent fault protection performance.
