RES2K5 Equivalent & Substitute Parts

Part Overview

The RES2K5 is a 2.5k Ohm wirewound potentiometer manufactured by Ohmite, designed for panel mount applications requiring linear taper adjustment. This component is classified as Active product status with 700 units currently in stock. The RES2K5 operates at 12.5W power rating with a 1-turn rotation mechanism and solder lug termination, suitable for applications requiring precise resistive adjustment in industrial and control systems.

Identifying equivalent and substitute parts is necessary when the primary RES2K5 becomes unavailable, when design requirements mandate RoHS compliance, or when inventory constraints require alternative sourcing from the same manufacturer's product line.

Substitute Part Grouping Explanation

Substitute parts for the RES2K5 are identified based on electrical and mechanical parameter equivalence. The primary substitution criteria are:

• Resistance value: 2.5k Ohm
• Tolerance: ±10%
• Power rating: 12.5W
• Taper type: Linear
• Number of turns: 1
• Rotation angle: 300°
• Resistive material: Wirewound
• Termination: Solder Lug
• Mounting configuration: Panel Mount with 1/4-32 bushing thread
• Physical dimensions: Round body 0.875" diameter

The RES2K5E meets all electrical and mechanical specifications identical to the RES2K5, with the distinction of RoHS3 compliance status, making it a direct functional equivalent suitable for applications requiring regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The RES2K5E serves as the direct substitute for the RES2K5 when component selection requires RoHS3 compliance. Both parts maintain identical electrical performance and mechanical compatibility. The RES2K5E carries higher inventory availability at 951 units compared to 700 units for the RES2K5, supporting supply chain continuity. Both components retain Active product status from Ohmite, confirming ongoing manufacturer support and availability. Selection between these parts depends on regulatory requirements: applications subject to RoHS3 mandates must use RES2K5E, while applications without such constraints may use either part based on inventory and delivery considerations.

Frequently Asked Questions (FAQ)

Q: Are RES2K5 and RES2K5E electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 2.5k Ohm resistance, ±10% tolerance, 12.5W power rating, linear taper, and 1-turn rotation. They are direct functional equivalents.

Q: What is the primary difference between RES2K5 and RES2K5E?

A: The RES2K5E is RoHS3 compliant, while the RES2K5 is RoHS non-compliant. All other electrical and mechanical parameters are identical.

Q: Can RES2K5E replace RES2K5 in existing designs?

A: Yes. The RES2K5E maintains identical mechanical dimensions, mounting configuration, termination style, and bushing thread specification (1/4-32), ensuring direct board-level compatibility without design modification.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. If RoHS3 compliance is mandated, specify RES2K5E. If no compliance requirement exists, either part is acceptable based on availability and delivery schedule.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical performance across all specified electrical and mechanical parameters.

Q: What inventory levels are available?

A: RES2K5 has 700 units in stock, while RES2K5E has 951 units in stock, both listed as new original inventory.
