RJS35R Equivalent & Substitute Parts

Part Overview

The RJS35R is a 35 Ohm, 50 Watt wirewound linear potentiometer manufactured by Ohmite, part of the J Series. This panel mount rheostat features a flatted actuator with solder lug termination and is designed for applications requiring precise resistance adjustment in high-power environments. The part is currently in active production status. Substitute parts may be required due to inventory availability, packaging preferences, or specific compliance requirements for end-use applications.

Substitute Part Grouping Explanation

The RJS35RE qualifies as a direct substitute for the RJS35R based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 35 Ohms (exact match)
• Power rating: 50W (exact match)
• Taper characteristic: Linear (exact match)
• Number of turns: 1.0 (exact match)
• Resistive material: Wirewound (exact match)
• Termination: Solder Lug (exact match)
• Mounting configuration: Panel Mount (exact match)
• Rotation angle: 300° (exact match)
• Bushing thread specification: 3/8-32 (exact match)
• Tolerance: ±10% (exact match)

Both parts are manufactured by Ohmite within the J Series and maintain identical functional specifications for circuit integration.

Parameter Comparison

Engineering Selection Recommendations

The RJS35RE is a direct functional equivalent to the RJS35R for all electrical and mechanical circuit requirements. Both parts are active products from Ohmite's J Series and maintain identical resistance, power rating, taper, termination, and mounting specifications.

The primary distinction between these parts is regulatory compliance status. The RJS35RE carries RoHS Compliant certification, while the RJS35R is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the RJS35RE is the appropriate selection. For applications without RoHS requirements, either part satisfies the functional specification.

Packaging differs between the two parts: RJS35R is supplied in standard packaging, while RJS35RE is supplied in bulk packaging. Bulk packaging may affect procurement quantities and storage considerations but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can RJS35RE replace RJS35R in existing designs?

A: Yes. The RJS35RE is electrically and mechanically identical to the RJS35R. All circuit parameters, mounting dimensions, and performance characteristics are equivalent. The parts are interchangeable from a functional standpoint.

Q: What is the difference in RoHS compliance between these parts?

A: The RJS35R is RoHS non-compliant, while the RJS35RE is RoHS Compliant. If your application or customer requirements mandate RoHS compliance, specify the RJS35RE. If RoHS compliance is not a requirement, both parts are functionally suitable.

Q: Are the packaging differences significant?

A: The RJS35R uses standard packaging while the RJS35RE uses bulk packaging. This affects order quantities and storage but does not impact the electrical or mechanical performance of the potentiometer. Select based on your procurement and inventory requirements.

Q: Do both parts have the same actuator and mounting specifications?

A: Yes. Both the RJS35R and RJS35RE feature identical flatted actuators (0.875" length, 0.250" diameter), 3/8-32 bushing threads, and panel mount configurations. Physical installation is identical.

Q: What is the Moisture Sensitivity Level difference?

A: The RJS35R lists MSL as Not Applicable, while the RJS35RE specifies MSL 1 (Unlimited). This indicates different handling and storage classifications, though both parts are suitable for standard industrial environments.
