RES3R0 Equivalent & Substitute Parts

Part Overview

The RES3R0 is a 3 Ohm, 12.5W wirewound linear potentiometer manufactured by Ohmite, designed for panel mount applications with a 1/4-32 bushing thread and solder lug termination. This component is currently Active in product status. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different packaging or compliance requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RES3R0 potentiometer is determined by strict equivalence across all electrical and mechanical parameters. The substitute part RES3R0E maintains identical specifications for resistance value, power rating, taper characteristic, number of turns, gang configuration, resistive material composition, termination method, mounting configuration, bushing thread specification, rotation angle, body dimensions, and actuator geometry. The primary distinction between the main part and its substitute is the packaging format and RoHS compliance status. Substitution is valid when all listed parameters remain unchanged.

Engineering Selection Recommendations

The RES3R0E serves as a direct electrical and mechanical equivalent to the RES3R0. Both parts are manufactured by Ohmite and maintain Active product status. The RES3R0E provides ROHS3 compliance, whereas the RES3R0 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application. The RES3R0E is supplied in Bulk packaging, while the RES3R0 packaging specification is not defined. Both parts are identical in all electrical parameters, mechanical dimensions, and functional characteristics. REACH status is Unaffected for both parts, and both carry ECCN classification EAR99 and HTSUS code 8533.31.0000.

Frequently Asked Questions (FAQ)

Q: Can RES3R0E replace RES3R0 in existing designs? A: Yes. The RES3R0E is electrically and mechanically identical to the RES3R0 across all specified parameters including resistance, power rating, taper, termination, mounting configuration, and physical dimensions.

Q: What is the difference between RES3R0 and RES3R0E? A: The primary differences are packaging format and RoHS compliance status. RES3R0E is ROHS3 compliant and supplied in Bulk packaging, while RES3R0 is RoHS non-compliant with unspecified packaging.

Q: Are there any compatibility concerns when substituting these parts? A: No compatibility concerns exist. Both parts share identical electrical and mechanical specifications, including the 1/4-32 bushing thread, solder lug termination, panel mount configuration, and all dimensional parameters.

Q: Which part should be selected for new designs? A: Selection depends on regulatory and compliance requirements. If ROHS3 compliance is required, specify RES3R0E. If RoHS compliance is not a design requirement, either part is functionally equivalent.

Q: Are both parts currently available? A: Both parts are listed as Active in product status. RES3R0 has 1033 Pcs in stock, and RES3R0E has 895 Pcs in stock.
