Substitute Part Grouping Explanation

Substitution for the LKN-25 is based on the following criteria established by the manufacturer:

• Electrical Classification: Both main and substitute parts fall under HTSUS code 8536.10.0040, confirming functional equivalence within fuse product categories
• Regulatory Compliance: RoHS compliance is maintained across all substitute options
• Manufacturer Continuity: All substitutes are sourced from Eaton - Bussmann Electrical Division, ensuring design and performance consistency
• Export Classification: ECCN EAR99 designation remains consistent, indicating no change in export control requirements

The LPN-RK-25SP is designated as the manufacturer-recommended substitute, representing the active product line replacement for the obsolete LKN-25.

Parameter Comparison

Engineering Selection Recommendations

The LPN-RK-25SP is the manufacturer-designated substitute for the obsolete LKN-25. Both components maintain identical regulatory compliance profiles, including RoHS certification and EAR99 export classification. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Selection of the LPN-RK-25SP eliminates obsolescence risk while preserving compliance requirements and electrical classification consistency.

Frequently Asked Questions (FAQ)

Q: Can the LPN-RK-25SP directly replace the LKN-25 in existing applications?

A: The LPN-RK-25SP is the manufacturer-recommended substitute designated by Eaton - Bussmann Electrical Division. Both parts share identical HTSUS classification (8536.10.0040), RoHS compliance status, and ECCN designation (EAR99), confirming functional equivalence within the fuse product category.

Q: What is the difference between SUPER LAG RENEWABLE LINK and LOW PEAK DUAL ELEMENT designations?

A: These designations reflect different fuse technologies within the Eaton - Bussmann product portfolio. The LPN-RK-25SP represents the active product line technology, while the LKN-25 represents an obsolete design. Both are classified under the same electrical and tariff codes.

Q: Are there packaging differences between the main part and substitute?

A: Both the LKN-25 and LPN-RK-25SP are supplied in bulk packaging format, ensuring consistency in handling and storage procedures.

Q: Does the MSL rating change with substitution?

A: The LKN-25 carries an MSL rating of 1 (Unlimited). The LPN-RK-25SP lists MSL as Not Applicable, indicating different moisture sensitivity classification for the substitute technology.

Q: Is inventory availability a consideration for part selection?

A: Current inventory shows 864 units of the LKN-25 and 1145 units of the LPN-RK-25SP in stock. Long-term availability is assured only through the active LPN-RK-25SP product line.
