RES-3 Equivalent & Substitute Parts

Part Overview

The RES-3 is a Super Lag Renewable Fuse manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, necessitating identification of active equivalent alternatives for continued system support and procurement. The RES-3 operates within electrical protection applications requiring time-delay fuse characteristics. Due to its obsolete status, sourcing equivalent parts with matching electrical and mechanical parameters is essential for system maintenance and replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RES-3 is determined by alignment of the following critical parameters:

• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Product Category: Fuse (functional equivalence in electrical protection)
• Packaging: Bulk (consistent with original procurement format)
• RoHS Compliance: RoHS Compliant (regulatory requirement maintained)
• HTSUS Classification: 8536.10.0040 (tariff code alignment confirms product classification equivalence)
• ECCN Code: EAR99 (export control classification consistency)

The substitute part LPS-RK-3SP meets all specified parameters and represents an active product alternative to the obsolete RES-3.

Parameter Comparison

Engineering Selection Recommendations

The LPS-RK-3SP is the manufacturer-recommended substitute for the obsolete RES-3. Selection of this alternative part is based on the following engineering criteria:

• Regulatory Compliance: Both parts maintain RoHS Compliant status, ensuring compatibility with current environmental and safety standards.
• Manufacturer Continuity: Both components are sourced from Eaton - Bussmann Electrical Division, providing design and performance consistency.
• Product Status: The LPS-RK-3SP is an active product with confirmed inventory availability (817 Pcs), whereas the RES-3 is obsolete with limited remaining stock.
• Classification Alignment: Identical HTSUS and ECCN codes confirm functional and regulatory equivalence.
• Packaging Consistency: Bulk packaging format remains unchanged, supporting existing procurement and handling procedures.

The LPS-RK-3SP is suitable for direct substitution in applications previously specified for the RES-3.

Frequently Asked Questions (FAQ)

Q: Why is the RES-3 being discontinued?
