RHS250 Equivalent & Substitute Parts

Part Overview

The RHS250 is a 250 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 and is currently in stock with 993 units available. The RHS250 serves as a user-adjustable resistive element in applications requiring precise resistance control with high power dissipation capability. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and termination methods align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RHS250 are identified based on strict equivalence across the following critical parameters: resistance value (250 Ohms), power rating (25W), tolerance (±10%), taper type (Linear), number of turns (1), rotation angle (300°), resistive material (Wirewound), termination style (Solder Lug), mounting type (Panel Mount), bushing thread specification (3/8-32), actuator dimensions, and body size. All substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement capability without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The RHS250E serves as a direct electrical and mechanical equivalent to the RHS250. Both components are manufactured by Ohmite within the H series and maintain identical specifications across all critical functional parameters. The primary distinction between these parts is regulatory compliance status. The RHS250E achieves ROHS3 compliance and REACH Unaffected certification, whereas the RHS250 is classified as RoHS non-compliant. Selection between these parts should be based on applicable regulatory requirements within the target application and end-use market. Both parts maintain Active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can RHS250E replace RHS250 in existing designs? A: Yes. The RHS250E is electrically and mechanically equivalent to the RHS250. All electrical parameters (resistance, power rating, tolerance, taper, rotation) and mechanical dimensions (bushing thread, actuator dimensions, body size, mounting type) are identical. Direct substitution is possible without circuit modification or mechanical redesign.

Q: What is the difference between RHS250 and RHS250E? A: The primary difference is regulatory compliance. RHS250E is ROHS3 compliant and REACH Unaffected, while RHS250 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there inventory considerations when selecting between RHS250 and RHS250E? A: RHS250 has 993 units in stock, while RHS250E has 795 units available. Selection may be influenced by immediate availability requirements and regulatory compliance mandates for the application.

Q: What parameters define substitutability for the RHS250? A: Substitute parts must match the following specifications: 250 Ohm resistance, 25W power rating, ±10% tolerance, linear taper, 1 turn, 300° rotation, wirewound resistive material, solder lug termination, panel mount configuration, 3/8-32 bushing thread, flatted actuator type, 0.750" actuator length, 0.250" actuator diameter, and 1.560" round body diameter.

Q: Is the RHS250 suitable for new designs requiring RoHS compliance? A: The RHS250 is RoHS non-compliant. For applications requiring RoHS compliance, the RHS250E is the appropriate selection, as it meets ROHS3 standards.
