LKN-200B Equivalent & Substitute Parts

Part Overview

The LKN-200B is a Super Lag Renewable Link fuse manufactured by Eaton - Bussmann Electrical Division. This component is classified as an obsolete product, necessitating identification of active equivalent alternatives for continued system support and procurement. The part maintains RoHS compliance and is suitable for applications requiring renewable fuse technology in the 200/250 ampere range.

Substitute Part Grouping Explanation

The LKN-200B has been identified with one manufacturer-recommended substitute: LPN-RK-200SP. This substitution is based on the following alignment criteria:

• Identical manufacturer (Eaton - Bussmann Electrical Division)
• Matching HTSUS classification (8536.10.0040)
• Identical ECCN designation (EAR99)
• RoHS compliance maintained in substitute
• Both classified as fuse components within electrical protection category

The LPN-RK-200SP represents an active product alternative, enabling continued procurement and system integration where the obsolete LKN-200B is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The LPN-RK-200SP is the manufacturer-designated substitute for the obsolete LKN-200B. Both components share identical regulatory classifications (ECCN and HTSUS), maintain RoHS compliance, and originate from the same manufacturer. The transition from the LKN-200B to LPN-RK-200SP is supported by regulatory alignment and active product status of the substitute.

For new designs or system replacements, the LPN-RK-200SP should be specified. Existing inventory of LKN-200B units may be utilized until depletion, after which transition to the active substitute is required.

Frequently Asked Questions (FAQ)

Q: Why is the LKN-200B no longer available? A: The LKN-200B has reached obsolete status in the manufacturer's product lifecycle. The LPN-RK-200SP represents the active equivalent for continued procurement.

Q: Are the LKN-200B and LPN-RK-200SP electrically interchangeable? A: Both components are classified as fuses with identical HTSUS and ECCN designations, manufactured by Eaton - Bussmann Electrical Division, and maintain RoHS compliance. Substitution is manufacturer-recommended.

Q: What is the difference in packaging between these parts? A: The LKN-200B is supplied in standard packaging, while the LPN-RK-200SP is available in bulk packaging. Bulk packaging may affect procurement quantities and storage requirements.

Q: Are both parts RoHS compliant? A: Yes, both the LKN-200B and LPN-RK-200SP are RoHS compliant, meeting environmental and regulatory requirements for electrical components.

Q: Can I use remaining LKN-200B inventory in new applications? A: The LKN-200B may be used in existing systems until inventory is depleted. For new designs and future procurement, specify the LPN-RK-200SP.
