RJS500 Equivalent & Substitute Parts

Part Overview

The RJS500 is a 500 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 949 units available. The RJS500 serves as a user-adjustable resistive element in applications requiring precise resistance control at elevated power levels. Substitute parts become necessary when addressing RoHS compliance requirements, managing inventory across supply chains, or accommodating specific regulatory certifications in end-use applications.

Key Parameters

Substitute Part Grouping Explanation

The RJS500E qualifies as a direct substitute for the RJS500 based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following critical parameters:

• Resistance value: 500 Ohms (exact match)
• Power rating: 50W (exact match)
• Taper characteristic: Linear (exact match)
• Number of turns: 1 (exact match)
• Resistive material: Wirewound (exact match)
• Termination style: Solder Lug (exact match)
• Mounting configuration: Panel Mount (exact match)
• Physical dimensions: Round body 2.310" diameter, 3/8-32 bushing thread (exact match)
• Actuator specifications: Flatted type, 0.875" length, 0.250" diameter (exact match)
• Rotation angle: 300° (exact match)

The RJS500E maintains full electrical and mechanical compatibility with the RJS500, differing only in regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The RJS500E is the direct equivalent substitute for the RJS500. Both components are manufactured by Ohmite within the J series and maintain identical electrical performance and mechanical form factor. The primary distinction is regulatory compliance: the RJS500E carries ROHS3 compliance certification and REACH Unaffected status, whereas the RJS500 is RoHS non-compliant.

Selection between these parts should be based on end-use application requirements. Applications subject to RoHS3 regulatory mandates or requiring REACH compliance documentation must specify the RJS500E. Applications without such regulatory constraints may utilize either part. Both components maintain Active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the RJS500E be used as a direct replacement for the RJS500 in existing designs?

A: Yes. The RJS500E provides identical electrical and mechanical performance. All physical dimensions, mounting interfaces, electrical ratings, and operational characteristics are equivalent. No design modifications are required for substitution.

Q: What is the primary difference between RJS500 and RJS500E?

A: The RJS500E meets ROHS3 compliance and REACH Unaffected certification, while the RJS500 does not carry these certifications. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with panel mount installation?

A: No. Both parts feature identical panel mount specifications: 3/8-32 bushing thread, 2.310" diameter round body, and flatted actuator with 0.875" length and 0.250" diameter. Installation procedures and mechanical interfaces are identical.

Q: Which part should be selected for new designs?

A: For new designs, the RJS500E is the appropriate selection due to its ROHS3 compliance and REACH Unaffected status, ensuring compatibility with current regulatory requirements and supply chain standards.

Q: Do both parts have the same solder lug termination?

A: Yes. Both the RJS500 and RJS500E utilize solder lug termination style, providing identical electrical connection methods and PCB integration approaches.
