RJS150 Equivalent & Substitute Parts

Part Overview

The RJS150 is a 150 Ohm, 50W wirewound linear potentiometer manufactured by Ohmite, designed for panel mount applications with solder lug termination. This component is classified as Active product status and is currently in stock with 1053 units available. The RJS150 operates with a 300° rotation angle, 1-turn configuration, and linear taper suitable for user-defined adjustment applications. Finding equivalent substitute parts is necessary to ensure supply chain continuity, evaluate compliance requirements, and maintain design flexibility across production batches.

Substitute Part Grouping Explanation

Substitute parts for the RJS150 are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion requires identical specifications across all critical parameters: 150 Ohm resistance value, 50W power rating, linear taper, 1-turn configuration, wirewound resistive material, solder lug termination, panel mount configuration, 300° rotation, and matching mechanical dimensions including 3/8-32 bushing thread and body diameter of 2.310" (58.67mm).

The RJS150E qualifies as a direct substitute because it maintains all electrical parameters (150 Ohms, ±10% tolerance, 50W, linear taper, 1-turn, wirewound) and all mechanical parameters (panel mount, solder lug, 300° rotation, 3/8-32 bushing, 2.310" body diameter, flatted actuator with 0.875" length and 0.250" diameter). Both parts belong to the Ohmite J series and share identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The RJS150E serves as a direct electrical and mechanical substitute for the RJS150. Both parts maintain identical functional specifications across all critical parameters including resistance value, power rating, taper characteristic, mechanical dimensions, and mounting configuration.

A key distinction exists in regulatory compliance status. The RJS150E achieves ROHS3 compliance and REACH Unaffected status, whereas the RJS150 is classified as RoHS non-compliant. For applications subject to RoHS3 or REACH regulatory requirements, the RJS150E is the appropriate selection. For applications without such regulatory constraints, both parts are functionally equivalent.

Inventory availability shows 945 units of RJS150E and 1053 units of RJS150 in stock, providing supply flexibility for either selection.

Frequently Asked Questions (FAQ)

Q: What makes RJS150E a valid substitute for RJS150?

A: The RJS150E maintains identical electrical specifications (150 Ohms, ±10% tolerance, 50W power rating, linear taper, 1-turn wirewound configuration) and mechanical specifications (panel mount, solder lug termination, 300° rotation, 3/8-32 bushing thread, 2.310" body diameter, flatted actuator dimensions). All critical parameters for potentiometer substitution are matched.

Q: Are there differences between RJS150 and RJS150E?

A: The primary difference is regulatory compliance. RJS150E is ROHS3 compliant and REACH Unaffected, while RJS150 is RoHS non-compliant. Functionally and mechanically, both parts are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 or REACH compliance, specify RJS150E. For applications without such requirements, either part is suitable based on availability and supply chain considerations.

Q: Can RJS150 and RJS150E be used interchangeably in existing assemblies?

A: Yes. Both parts share identical electrical and mechanical specifications, including mounting configuration, termination style, and dimensional characteristics. Direct substitution is possible without circuit or mechanical redesign.

Q: What are the key parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: resistance value (150 Ohms), power rating (50W), taper type (linear), number of turns (1), resistive material (wirewound), termination style (solder lug), mounting type (panel mount), rotation angle (300°), bushing thread (3/8-32), and body diameter (2.310"). All these parameters must match for direct substitution.
