LKN-35 Equivalent & Substitute Parts

Part Overview

The LKN-35 is a Super Lag Renewable Link fuse manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing maintenance and system continuity. The part operates within electrical protection applications where renewable fuse technology was previously specified. Due to its obsolete status, sourcing direct replacements requires evaluation of functionally equivalent alternatives that maintain compliance with original electrical and mechanical specifications.

Substitute Part Grouping Explanation

The LKN-35 has been superseded by the LPN-RK-35SP, a Low Peak Dual Element fuse from the same manufacturer. Substitution is based on the following alignment criteria:

• Manufacturer continuity: Both parts are manufactured by Eaton - Bussmann Electrical Division
• Electrical classification: Both are fuse components within HTSUS code 8536.10.0040
• Compliance standards: Both maintain RoHS Compliant status and EAR99 export classification
• Functional category: The LPN-RK-35SP represents the active product line replacement for the obsolete LKN-35 renewable link technology

Parameter Comparison

Engineering Selection Recommendations

The LPN-RK-35SP is the manufacturer-designated substitute for the obsolete LKN-35. Both components share identical export classification (EAR99) and regulatory compliance (RoHS Compliant), confirming compatibility within the same regulatory framework. The LPN-RK-35SP maintains active product status with established supply availability, whereas the LKN-35 is no longer in production. Selection of the LPN-RK-35SP ensures continuity of supply and compliance with current manufacturing standards while maintaining the same electrical protection classification.

Frequently Asked Questions (FAQ)

Q: Why is the LKN-35 being replaced? A: The LKN-35 is classified as obsolete and is no longer manufactured. The LPN-RK-35SP is the active equivalent from Eaton - Bussmann Electrical Division.

Q: Are the LKN-35 and LPN-RK-35SP electrically equivalent? A: Both components are fuses within the same HTSUS classification (8536.10.0040) and share identical export and compliance designations (EAR99, RoHS Compliant), confirming functional equivalence within the electrical protection category.

Q: What is the difference in packaging between these parts? A: The LKN-35 packaging is not specified in available documentation. The LPN-RK-35SP is supplied in Bulk packaging.

Q: Can I use the LPN-RK-35SP as a direct replacement for the LKN-35? A: The LPN-RK-35SP is the manufacturer-recommended substitute. Verification of mechanical fit and electrical ratings within your specific application is required before implementation.

Q: Are both parts RoHS compliant? A: Yes, both the LKN-35 and LPN-RK-35SP are RoHS Compliant.
