Key Parameters

Substitute Part Grouping Explanation

The REN-45 has been identified with one manufacturer-recommended substitute: LPN-RK-45SP. This substitution is based on the following alignment criteria:

• Identical manufacturer (Eaton - Bussmann Electrical Division)
• Matching electrical rating (45/250)
• Identical HTSUS classification (8536.10.0040)
• Equivalent RoHS compliance status
• Shared ECCN designation (EAR99)

The LPN-RK-45SP is classified as a Low Peak Dual Element fuse, representing the active product line successor to the obsolete REN-45 series. Both components fall within the same regulatory and compliance framework, supporting direct substitution in applications where the electrical characteristics align with system requirements.

Parameter Comparison

Engineering Selection Recommendations

The LPN-RK-45SP is the manufacturer-designated substitute for the obsolete REN-45. Both components share identical electrical ratings (45/250), equivalent compliance certifications (RoHS Compliant, EAR99), and matching tariff classifications. The LPN-RK-45SP maintains active product status within the Eaton - Bussmann product line, ensuring continued availability and support for future procurement requirements. Selection between these components should be based on application-specific packaging requirements and inventory availability, as both satisfy the established electrical and regulatory parameters for this fuse category.
