KTS-R-20 Equivalent & Substitute Parts

Part Overview

The KTS-R-20 is a fast-acting AC/DC fuse manufactured by Eaton - Bussmann Electrical Division, classified as a FUSE LIMITRON FAST ACTING component. This part is actively produced and RoHS compliant, making it suitable for electrical and industrial applications requiring reliable overcurrent protection. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements where equivalent electrical and mechanical parameters are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KTS-R-20 is based on the following critical parameters:

• Current Rating: 20A
• Voltage Rating: AC and DC operation capability
• Response Time: Fast-acting characteristics
• Fuse Type: Cartridge configuration
• Approval Standards: Industry certifications (UL, CSA, CE)
• RoHS Compliance: Environmental regulatory alignment

The KLSR020.T from Littelfuse Inc. qualifies as a substitute based on matching current rating (20A), dual voltage operation (600 VAC / 250 VDC), fast-blow response time, and equivalent regulatory compliance. Both parts are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both the KTS-R-20 and KLSR020.T are active products with current manufacturing status. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Bulk vs. Box)
• Manufacturer preference or supply chain constraints
• Compliance certifications required for the end application (both parts carry UL, CSA, and CE approvals)
• RoHS compliance level requirements (both parts meet RoHS standards)

The KLSR020.T provides documented voltage ratings (600 VAC / 250 VDC) and breaking capacity specifications (200kA AC, 20kA DC), which may be relevant for detailed circuit analysis and application verification.

Frequently Asked Questions (FAQ)

Q: What makes KLSR020.T a valid substitute for KTS-R-20?

A: Both parts share the same current rating (20A), fast-acting response characteristics, cartridge fuse type, and equivalent regulatory compliance (RoHS, EAR99, HTSUS classification). Both are active products from established manufacturers.

Q: Are there packaging differences between these parts?

A: Yes. The KTS-R-20 is supplied in Bulk packaging, while the KLSR020.T is supplied in Box packaging. This may affect ordering quantities and storage requirements but does not impact electrical performance.

Q: Do both parts require a holder for installation?

A: The KLSR020.T is documented as requiring a holder. The KTS-R-20 input data does not specify holder requirements; this should be verified against the manufacturer's datasheet for your specific application.

Q: Are the voltage ratings identical?

A: The KLSR020.T is rated for 600 VAC / 250 VDC operation. The KTS-R-20 voltage ratings are not specified in the provided input data. Verify voltage compatibility with your application requirements and manufacturer documentation.

Q: Can these parts be used interchangeably in all applications?

A: Substitution is valid where the 20A current rating, fast-acting response time, and cartridge form factor are the controlling design parameters. Verify mechanical fit, holder compatibility, and voltage requirements for your specific circuit before implementation.
