RJS10K Equivalent & Substitute Parts

Part Overview

The RJS10K is a 10k Ohm 50W wirewound linear potentiometer manufactured by Ohmite, designed for panel mount applications with a 1-turn adjustment mechanism. This component is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the same product category, enabling procurement flexibility and inventory optimization while preserving circuit performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The RJS10KE qualifies as a direct substitute for the RJS10K based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 10k Ohm (±10% tolerance)
• Power dissipation capability: 50W
• Taper characteristic: Linear
• Number of turns: 1
• Resistive element material: Wirewound
• Termination configuration: Solder Lug
• Panel mount mechanical interface: 3/8-32 bushing thread
• Body envelope: Round 2.310" diameter
• Rotation angle: 300°

Both parts maintain these specifications, confirming functional and mechanical interchangeability within the RJS series.

Parameter Comparison

Engineering Selection Recommendations

Both RJS10K and RJS10KE are active production components from Ohmite's J series. The RJS10KE offers RoHS3 compliance and REACH unaffected status, whereas the RJS10K is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. The RJS10KE is available in bulk packaging with significantly higher inventory levels (20,199 pcs vs. 800 pcs), supporting extended production runs and supply chain continuity. Both parts are electrically and mechanically identical, ensuring direct substitution without circuit redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can RJS10KE replace RJS10K in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance, power rating, taper, termination, and mechanical envelope. Direct substitution is valid without design modification.

Q: What is the difference between RJS10K and RJS10KE? A: The primary differences are packaging format (RJS10K supplied with dash packaging; RJS10KE in bulk) and regulatory compliance status (RJS10KE is RoHS3 compliant and REACH unaffected; RJS10K is RoHS non-compliant). Electrical and mechanical specifications are identical.

Q: Which part should be selected for new designs? A: RJS10KE is recommended for new designs due to active production status, higher inventory availability, and RoHS3 compliance, which aligns with current regulatory standards in most markets.

Q: Are there any mechanical compatibility concerns when substituting these parts? A: No. Both parts share identical mechanical specifications: 3/8-32 bushing thread, 2.310" round body diameter, 0.875" flatted actuator length, and 0.250" actuator diameter. Panel mount installation is identical.

Q: What packaging options are available? A: RJS10K is available in dash packaging (800 pcs in stock). RJS10KE is available in bulk packaging (20,199 pcs in stock). Packaging selection depends on procurement volume and supply chain requirements.
