Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KLM-1-1/2 is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 1.5A (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) or equivalent 5AG/10mm x 38mm standard
• Breaking Capacity: 100kA AC, 50kA DC (minimum requirement)
• Approval Certifications: CE, CSA, UL (all three required)
• Mounting Type: Requires Holder (exact match required)

The KLKD01.5T from Littelfuse Inc. meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the KLM-1-1/2 and KLKD01.5T are Active products with identical electrical specifications and approval certifications (CE, CSA, UL). Physical dimensions are equivalent within manufacturing tolerance (10.30mm vs. 10.31mm diameter). Both components meet RoHS compliance requirements. Selection between these parts should be based on availability, packaging format preference (Bulk vs. Box), and inventory status. The KLKD01.5T is suitable for applications requiring solar photovoltaic compatibility in addition to general electrical and industrial use.

Frequently Asked Questions (FAQ)

Q: Can the KLKD01.5T replace the KLM-1-1/2 in existing installations?

A: Yes. Both parts are 1.5A 600VAC/VDC fast-blow cartridge fuses with identical breaking capacity and approval certifications. Physical dimensions are equivalent (0.406" Dia x 1.500" L), ensuring compatibility with standard 5AG/10mm x 38mm fuse holders.

Q: What are the critical parameters for substitution?

A: Current rating (1.5A), voltage ratings (600 VAC and 600 VDC), response time (Fast Blow), fuse type (Cartridge), physical dimensions (0.406" Dia x 1.500" L), breaking capacity (100kA AC, 50kA DC), and approval certifications (CE, CSA, UL) must all match exactly.

Q: Are there differences in packaging between these parts?

A: The KLM-1-1/2 is supplied in Bulk packaging, while the KLKD01.5T is supplied in Box packaging. This does not affect electrical or mechanical compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. The KLM-1-1/2 is RoHS Compliant, and the KLKD01.5T is ROHS3 Compliant. Both maintain Active product status and carry CE, CSA, and UL certifications.

Q: What is the physical tolerance between these parts?

A: Diameter tolerance is 10.30mm (KLM-1-1/2) versus 10.31mm (KLKD01.5T), a difference of 0.01mm within standard manufacturing tolerance. Length is identical at 38.10mm for both parts.
