Key Parameters

Substitute Part Grouping Explanation

The KLSR300.X manufactured by Littelfuse Inc. is identified as an equivalent substitute for the KTS-R-300 based on the following critical parameters:

• Current Rating: 300A
• Voltage Rating - AC: 600 VAC
• Voltage Rating - DC: 300 VDC
• Response Time: Fast Blow
• Fuse Type: Cartridge
• Class: RK1
• ECCN Classification: EAR99
• HTSUS Code: 8536.10.0040

Both parts share identical electrical ratings and regulatory classifications, establishing functional equivalence for applications requiring 300A fast-acting fuse protection at 600 VAC / 300 VDC.

Parameter Comparison

Engineering Selection Recommendations

Both the KTS-R-300 and KLSR300.X maintain Active product status with current manufacturing support. The KTS-R-300 carries RoHS Compliant certification, while the KLSR300.X meets the more stringent ROHS3 Compliant standard. Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming regulatory equivalence for export and tariff purposes. Selection between these parts should be based on packaging requirements (Bulk versus Box), inventory availability, and lead time considerations, as both satisfy the electrical and compliance requirements for 300A fast-acting fuse applications.
