RHS3K5 Equivalent & Substitute Parts

Part Overview

The RHS3K5 is a 3.5k Ohm wirewound potentiometer rated for 25W power dissipation, manufactured by Ohmite in the H series. This linear panel mount potentiometer features a 1-turn design with solder lug termination and is currently in active production status. Finding equivalent and substitute parts is necessary when the primary part number becomes unavailable, when bulk packaging is required, or when compliance requirements differ between applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RHS3K5 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.5k Ohm
• Power rating: 25W
• Tolerance: ±10%
• Taper characteristic: Linear
• Number of turns: 1
• Resistive material: Wirewound
• Termination: Solder Lug
• Mounting configuration: Panel Mount
• Mechanical dimensions: Bushing thread 3/8-32, body diameter 1.560"
• Rotation angle: 300°

The RHS3K5E qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all critical parameters. The primary difference is packaging format (bulk versus standard) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both RHS3K5 and RHS3K5E are active production parts from Ohmite's H series and are electrically and mechanically identical. Selection between these parts should be based on the following criteria:

RHS3K5 is appropriate for applications where RoHS non-compliant components are acceptable and standard packaging is sufficient.

RHS3K5E is appropriate for applications requiring ROHS3 compliance and bulk packaging formats. This part is suitable for high-volume production environments where bulk packaging reduces handling and logistics overhead.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.39.0080) classifications, indicating no difference in export control or tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can RHS3K5E be used as a direct replacement for RHS3K5?

A: Yes. The RHS3K5E is a direct electrical and mechanical equivalent. All critical parameters including resistance, power rating, tolerance, taper, termination, and mechanical dimensions are identical. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between RHS3K5 and RHS3K5E?

A: The RHS3K5E is supplied in bulk packaging, whereas the RHS3K5 uses standard packaging. Additionally, RHS3K5E is ROHS3 compliant while RHS3K5 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Does the bulk packaging of RHS3K5E affect performance?

A: No. Packaging format does not affect electrical performance or mechanical function. Bulk packaging is a logistics consideration only.

Q: Are there any compliance differences between these parts?

A: RHS3K5E is ROHS3 compliant, while RHS3K5 is RoHS non-compliant. Both parts are classified as REACH Unaffected or Not Applicable. Selection should be based on application compliance requirements.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the mounting configuration and panel cutout specifications match the 3/8-32 bushing thread and 1.560" body diameter. Both parts use identical solder lug termination and actuator specifications.
