RJSR50 Equivalent & Substitute Parts

Part Overview

The RJSR50 is a 0.5 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 1,037 units available. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility parameters are maintained across the same product category, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RJSR50 is determined by strict equivalence across the following critical parameters:

• Resistance value: 0.5 Ohm
• Power rating: 50W
• Taper characteristic: Linear
• Number of turns: 1
• Resistive material composition: Wirewound
• Termination method: Solder Lug
• Mounting configuration: Panel Mount
• Mechanical interface: 3/8-32 bushing thread
• Rotation angle: 300°
• Body diameter: 2.310" (58.67mm)

The RJSR50E qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. Differences in packaging format and compliance certifications do not affect functional interchangeability in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The RJSR50E is a functionally equivalent substitute for the RJSR50 across all electrical and mechanical specifications. Both components are manufactured by Ohmite and maintain identical performance characteristics for 0.5 Ohm, 50W wirewound linear potentiometer applications.

The primary distinction between these parts is compliance certification. The RJSR50E carries ROHS3 compliance and REACH Unaffected status, whereas the RJSR50 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application and target market. If RoHS3 compliance is mandated, the RJSR50E is the appropriate choice. If compliance requirements do not apply, either part satisfies the functional specification.

Packaging format differs between the two parts (standard versus bulk), which may influence procurement quantity and logistics considerations but does not affect component performance or interchangeability.

Frequently Asked Questions (FAQ)

Q: Can RJSR50E be used as a direct replacement for RJSR50 in existing designs?

A: Yes. The RJSR50E is electrically and mechanically identical to the RJSR50. All functional parameters, including resistance value, power rating, taper, termination style, and mechanical dimensions, are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between RJSR50 and RJSR50E?

A: The components are functionally identical. Differences exist in packaging format (standard versus bulk) and compliance certifications. The RJSR50E is ROHS3 compliant and REACH Unaffected, while the RJSR50 is RoHS non-compliant.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both compliant and non-compliant versions deliver identical functional characteristics for the specified application.

Q: Are there any mechanical compatibility issues when substituting RJSR50E for RJSR50?

A: No. Both parts share identical mechanical specifications: 3/8-32 bushing thread, 2.310" (58.67mm) body diameter, flatted actuator with 0.875" (22.23mm) length, and 0.250" (6.35mm) diameter. Panel mount installation is identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, specify RJSR50E. If compliance is not mandated, either part meets the functional specification. Verify compliance requirements with applicable standards for your target market and application.
