RES1K0 Equivalent & Substitute Parts

Part Overview

The RES1K0 is a 1k Ohm wirewound potentiometer rated at 12.5W with linear taper and panel mount configuration. Manufactured by Ohmite in the E series, this component is currently active in production. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate varying compliance requirements across different applications and regions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RES1K0 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RES1K0E maintains identical specifications for resistance value, power rating, taper characteristic, number of turns, gang configuration, resistive material composition, termination method, mounting interface, rotation angle, and physical dimensions. These parameters define the functional and mechanical compatibility of the component within its intended application.

The primary distinction between the main part and its substitute relates to regulatory compliance status, which does not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RES1K0 and RES1K0E are active production components from Ohmite's E series. Selection between these parts should be based on regulatory compliance requirements applicable to the end application.

The RES1K0E variant is ROHS3 compliant, making it suitable for applications subject to Restriction of Hazardous Substances regulations. The RES1K0 is RoHS non-compliant and appropriate for applications without such regulatory constraints.

Both parts maintain identical electrical performance, mechanical dimensions, and interface specifications. Inventory availability should also be considered in component selection, with RES1K0E currently stocked at 1024 pieces and RES1K0 at 976 pieces.

Frequently Asked Questions (FAQ)

Q: Can RES1K0E be used as a direct replacement for RES1K0?

A: Yes. RES1K0E is electrically and mechanically identical to RES1K0 across all specified parameters including resistance value, power rating, taper, termination style, mounting configuration, and physical dimensions.

Q: What is the difference between RES1K0 and RES1K0E?

A: The primary difference is RoHS compliance status. RES1K0E is ROHS3 compliant, while RES1K0 is RoHS non-compliant. Both parts are REACH unaffected and classified under ECCN EAR99.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both parts share identical mechanical specifications including panel mount configuration, 1/4-32 bushing thread, 0.875" diameter round body, slotted actuator design, and 300° rotation angle.

Q: Which part should be selected for new designs?

A: Selection depends on applicable regulatory requirements. For applications requiring RoHS compliance, specify RES1K0E. For applications without such requirements, either part is suitable based on availability and cost considerations.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both parts are rated at 1k Ohm with ±10% tolerance, 12.5W power rating, linear taper, wirewound resistive material, and single-turn, single-gang configuration.
