RHS8R0 Equivalent & Substitute Parts

Part Overview

The RHS8R0 is an 8 Ohm, 25W wirewound linear potentiometer manufactured by Ohmite, designed for panel mount applications with solder lug termination. This component is currently active in production with 1118 units in stock. The RHS8R0 is classified as RoHS non-compliant, which may necessitate identification of compliant alternatives for applications subject to RoHS regulations or customer requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RHS8R0 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part RHS8R0E maintains identical specifications for resistance, power rating, taper, number of turns, gangs, resistive material, termination style, mounting configuration, rotation angle, bushing thread size, body dimensions, and actuator geometry. The primary distinction between these parts is regulatory compliance status: the RHS8R0E is RoHS3 compliant and REACH unaffected, whereas the RHS8R0 is RoHS non-compliant. Both parts are manufactured by Ohmite within the H series and share the same ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

The RHS8R0E serves as a direct electrical and mechanical equivalent to the RHS8R0, with the distinction that RHS8R0E carries RoHS3 compliance certification and REACH unaffected status. Selection between these parts should be based on regulatory requirements applicable to the end application. For applications subject to RoHS directives or customer specifications mandating RoHS compliance, the RHS8R0E is the appropriate choice. For applications without such regulatory constraints, either part is functionally equivalent. Both parts maintain active production status and are available in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Are RHS8R0 and RHS8R0E electrically identical? A: Yes. Both parts have identical electrical specifications: 8 Ohm resistance, 25W power rating, ±10% tolerance, linear taper, and wirewound construction.

Q: Are the mechanical dimensions identical? A: Yes. Both parts share identical mechanical specifications including body diameter (1.560"), actuator geometry (0.750" length, 0.250" diameter), bushing thread (3/8-32), and panel mount configuration.

Q: What is the primary difference between these parts? A: The RHS8R0E is RoHS3 compliant and REACH unaffected, while the RHS8R0 is RoHS non-compliant. All other specifications are identical.

Q: Can RHS8R0E replace RHS8R0 in existing designs? A: Yes. The RHS8R0E is a direct substitute with no design modifications required, provided the application does not have specific non-compliance requirements.

Q: Are both parts available in the same packaging? A: Yes. Both parts are supplied in bulk packaging.

Q: What certifications apply to each part? A: RHS8R0 is classified as EAR99 with HTSUS 8533.39.0080. RHS8R0E carries the same classifications plus RoHS3 compliance and REACH unaffected status.
