Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KTN-R-25 are identified based on the following critical parameters:

• Current Rating: 25A
• Voltage Rating: 250 VAC / 125 VDC
• Response Time: Fast Blow
• Fuse Type: Cartridge
• Regulatory Compliance: RoHS compliance and international approval certifications (CE, CSA, UL)
• ECCN and HTSUS classification alignment

The KLNR025.T from Littelfuse Inc. meets these substitution criteria through equivalent electrical specifications and compatible mechanical form factor, enabling functional replacement in circuits designed for the KTN-R-25.

Parameter Comparison

Engineering Selection Recommendations

Both the KTN-R-25 and KLNR025.T are active production components with current regulatory compliance. The KTN-R-25 carries RoHS Compliant certification, while the KLNR025.T carries ROHS3 Compliant certification, indicating enhanced environmental compliance standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming equivalent trade and export regulatory treatment.

The KLNR025.T includes additional documented specifications: 200kA AC and 20kA DC breaking capacity at rated voltage, RK1 class rating, and approval certifications from CE, CSA, and UL. The cartridge form factor (0.563" Dia x 2.000" L) is standard for this current and voltage class.

Selection between these parts should be based on application-specific requirements, holder compatibility, and inventory availability. Both parts are suitable for electrical and industrial applications requiring 25A fast-acting fuse protection.

Frequently Asked Questions (FAQ)

Q: What makes KLNR025.T a valid substitute for KTN-R-25?

A: Both parts share the same current rating (25A), response time classification (fast-acting/fast blow), fuse type (cartridge), and regulatory classifications (ECCN EAR99, HTSUS 8536.10.0040). Both are active production components with current RoHS compliance certifications.

Q: Are there packaging differences between these parts?

A: Yes. The KTN-R-25 is supplied in Bulk packaging, while the KLNR025.T is supplied in Box packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects supplier distribution methods.

Q: Does the KLNR025.T require a specific holder?

A: The KLNR025.T is documented as requiring a holder for installation. Verify that your application circuit includes a compatible cartridge fuse holder rated for 25A, 250 VAC / 125 VDC operation.

Q: Are the voltage ratings identical?

A: The KTN-R-25 voltage specifications are not detailed in the provided data. The KLNR025.T is rated for 250 VAC / 125 VDC. Confirm that your application voltage requirements align with the KLNR025.T ratings before substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents a more recent revision of RoHS compliance standards with updated restricted substance requirements. Both certifications indicate environmental compliance; ROHS3 reflects current regulatory standards.
