Key Parameters

Substitute Part Grouping Explanation

Substitution of the KWS-R-300 is based on the following criteria derived from the provided parameters:

• Functional Type: Fast-acting fuse classification
• Manufacturer Consistency: Eaton - Bussmann Electrical Division
• Compliance Requirements: RoHS compliance and EAR99 export classification
• Tariff Classification: HTSUS code 8536.10.0040 alignment
• Moisture Sensitivity: MSL rating compatibility

The KTS-R-300 qualifies as a direct substitute based on matching functional description (fast-acting fuse), identical manufacturer, equivalent RoHS compliance status, and identical HTSUS classification. The KTS-R-300 maintains active product status, providing supply continuity for the obsolete KWS-R-300.

Parameter Comparison

Engineering Selection Recommendations

The KTS-R-300 is the designated substitute for the obsolete KWS-R-300. Both components are manufactured by Eaton - Bussmann Electrical Division and maintain identical RoHS compliance and export classification status. The KTS-R-300 carries active product status, ensuring long-term availability and supply chain reliability. Both parts satisfy the same HTSUS tariff classification, confirming functional and regulatory equivalence. Selection of the KTS-R-300 eliminates obsolescence risk while maintaining compliance requirements and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Why is the KWS-R-300 being phased out? A: The KWS-R-300 is classified as obsolete. The KTS-R-300 serves as the active replacement, providing equivalent fast-acting fuse functionality with continued manufacturer support.

Q: Are the KWS-R-300 and KTS-R-300 electrically equivalent? A: Both components are Limitron fast-acting fuses from Eaton - Bussmann Electrical Division with identical HTSUS classification and RoHS compliance status, confirming functional equivalence.

Q: What is the difference in packaging between these parts? A: The KWS-R-300 is supplied in standard packaging, while the KTS-R-300 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance requirements? A: Yes. Both the KWS-R-300 and KTS-R-300 are RoHS compliant and classified under ECCN EAR99, meeting identical regulatory requirements.

Q: Is inventory availability a factor in part selection? A: Both parts maintain adequate inventory levels (KWS-R-300: 891 pcs; KTS-R-300: 832 pcs). The KTS-R-300 is recommended due to active product status, ensuring sustained availability beyond current stock levels.
