Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KLSR015.T are identified based on the following critical parameters:

• Current Rating: 15A
• Voltage Rating: 600 VAC / 250 VDC
• Response Time: Fast Blow
• Fuse Type: Cartridge
• Class: RK1
• Breaking Capacity: 200kA AC / 20kA DC
• Physical Form Factor: Cartridge, Non-Standard (0.811" Dia x 5.000" L)

The KTS-R-15 from Eaton - Bussmann Electrical Division is identified as a manufacturer-recommended substitute. This part maintains compatibility through equivalent electrical performance characteristics and cartridge form factor suitable for use in the same holder assemblies.

Parameter Comparison

Engineering Selection Recommendations

Both the KLSR015.T and KTS-R-15 maintain Active product status and carry equivalent regulatory compliance classifications (EAR99, HTSUS 8536.10.0040). The KTS-R-15 is designated as the manufacturer-recommended substitute and carries RoHS compliance certification. Selection between these parts should be based on availability, packaging requirements (the KLSR015.T is supplied in Box packaging with 959 units in stock; the KTS-R-15 is supplied in Bulk packaging with 785 units in stock), and procurement lead times. Both parts satisfy the electrical and mechanical requirements for 15A cartridge fuse applications in 600 VAC / 250 VDC systems.

Frequently Asked Questions (FAQ)

Q: Can the KTS-R-15 be used as a direct replacement for the KLSR015.T?

A: Yes. Both parts are 15A fast-acting cartridge fuses with equivalent AC and DC voltage ratings. They share the same cartridge form factor and are suitable for use in compatible holder assemblies.

Q: Are there differences in breaking capacity between these parts?

A: The KLSR015.T specifies 200kA AC and 20kA DC breaking capacity. The KTS-R-15 specifications provided do not include explicit breaking capacity values; verification against the manufacturer's detailed datasheet is necessary for applications where breaking capacity is a critical design parameter.

Q: What is the difference between packaging options?

A: The KLSR015.T is supplied in Box packaging, while the KTS-R-15 is supplied in Bulk packaging. Packaging selection depends on inventory management practices and procurement quantities required for your application.

Q: Are both parts RoHS compliant?

A: Yes. The KLSR015.T is ROHS3 Compliant, and the KTS-R-15 is RoHS Compliant. Both meet current environmental compliance requirements.

Q: Do these parts require a specific holder assembly?

A: Yes. Both the KLSR015.T and KTS-R-15 are cartridge fuses that require a compatible holder for installation. Verify holder compatibility with the cartridge dimensions (0.811" Dia x 5.000" L) before procurement.
