RES10K Equivalent & Substitute Parts

Part Overview

The RES10K is a 10k Ohm wirewound potentiometer manufactured by Ohmite, designed for panel mount applications requiring linear taper adjustment. This component is rated for 12.5W power dissipation with a 1-turn rotation mechanism and solder lug termination. The part is currently Active in product status. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, compliance upgrades, or design standardization across production batches.

Engineering Selection Recommendations

Both RES10K and RES10KE are Active products suitable for 10k Ohm 12.5W wirewound potentiometer applications. The RES10KE provides an upgrade path for designs requiring RoHS3 compliance, while maintaining identical electrical and mechanical specifications. Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application. Both parts share equivalent REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can RES10KE be used as a direct replacement for RES10K in existing designs?

A: Yes. The RES10KE meets all electrical and mechanical specifications of the RES10K, including resistance value, power rating, taper type, rotation angle, termination style, and mounting dimensions. No design modifications are required for substitution.

Q: What is the primary difference between RES10K and RES10KE?

A: The RES10KE is RoHS3 compliant, while the RES10K is RoHS non-compliant. All other specifications are identical.

Q: Are there any compatibility concerns with panel mount installation?

A: No. Both parts feature identical bushing thread specifications (1/4-32), body diameter (0.875" Dia), and mounting type (Panel Mount), ensuring mechanical compatibility in existing panel cutouts and mounting hardware.

Q: Do these parts have different inventory availability?

A: Current inventory shows RES10K at 882 Pcs and RES10KE at 906 Pcs, both listed as New Original In Stock.

Q: Are there any differences in electrical performance between these substitutes?

A: No. Both parts share identical resistance (10k Ohm), tolerance (±10%), power rating (12.5W), and wirewound resistive material specifications.
