RHS350 Equivalent & Substitute Parts

Part Overview

The RHS350 is a 350 Ohm, 25W wirewound linear potentiometer manufactured by Ohmite, designed for panel mount applications with solder lug termination. This component is classified as Active product status with 972 units currently in stock. The RHS350 operates with a 300° rotation angle, 1-turn adjustment, and features a flatted actuator with 0.750" length and 0.250" diameter. Finding equivalent or substitute parts may be necessary due to supply chain considerations, compliance requirements, or specific application needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RHS350 are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on matching the following key criteria:

• Resistance value: 350 Ohms
• Power rating: 25W
• Taper characteristic: Linear
• Number of turns: 1
• Resistive material: Wirewound
• Termination: Solder Lug
• Mounting configuration: Panel Mount
• Physical dimensions and bushing thread specification
• Tolerance: ±10%

The RHS350E qualifies as a direct substitute because it maintains identical specifications across all these parameters while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The RHS350E serves as a direct electrical and mechanical equivalent to the RHS350. Both components maintain identical functional specifications and physical dimensions, ensuring drop-in compatibility in existing designs.

The primary distinction between these parts is compliance status. The RHS350E achieves ROHS3 compliance and REACH Unaffected status, whereas the RHS350 is RoHS non-compliant. For applications subject to RoHS Directive 2011/65/EU or REACH regulations, the RHS350E is the appropriate selection. Both components carry Active product status and are manufactured by Ohmite under the H series designation.

Selection between these parts should be based on regulatory requirements applicable to the end application and geographic market. Electrical performance, mechanical fit, and thermal characteristics are identical.

Frequently Asked Questions (FAQ)

Q: Can RHS350E replace RHS350 in existing designs?

A: Yes. The RHS350E is a direct substitute with identical electrical specifications (350 Ohm, 25W, linear taper), mechanical dimensions (1.560" body diameter, 3/8-32 bushing thread), and termination style (solder lug). Physical mounting and circuit integration remain unchanged.

Q: What is the difference between RHS350 and RHS350E?

A: The components are electrically and mechanically identical. The RHS350E provides ROHS3 compliance and REACH Unaffected certification, while the RHS350 does not carry these certifications. Both are Active products from Ohmite's H series.

Q: Which part should be selected for new designs?

A: For applications requiring RoHS or REACH compliance, specify RHS350E. For applications without regulatory compliance requirements, either part is functionally equivalent. Verify compliance obligations for your specific application and geographic market.

Q: Are the physical dimensions identical?

A: Yes. Both parts feature a 1.560" diameter round body, 0.750" flatted actuator length, 0.250" actuator diameter, and 3/8-32 bushing thread. Panel mount configuration and solder lug termination are identical.

Q: What is the tolerance specification?

A: Both RHS350 and RHS350E maintain ±10% tolerance on the 350 Ohm resistance value.
