Honeywell 392C2250K Potentiometer - Equivalent & Substitute Parts

Part Overview

The Honeywell 392C2250K is a 250k Ohm 1/2W linear panel mount potentiometer with conductive plastic resistive material and PC pin termination. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The 1-gang, single-turn design with slotted actuator and 295° rotation provides user-defined adjustment capability in panel-mounted applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 392C2250K is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (250k Ohm), power rating (0.5W, 1/2W), tolerance (±10%), and taper (Linear) must be identical
• Mechanical Configuration: Single-turn, single-gang design with 295° rotation and 1/4-32 bushing thread
• Physical Dimensions: Round body 0.510" diameter, slotted actuator 0.625" length and 0.125" diameter
• Mounting Interface: Panel mount configuration with compatible termination style

The primary distinction between the main part and substitute candidates is the resistive material composition (conductive plastic versus carbon) and termination style (PC pins versus solder lug). These differences do not affect functional equivalence when electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The Precision Electronics RV6LAYSA254A qualifies as a functional equivalent to the Honeywell 392C2250K based on complete alignment of electrical and mechanical specifications. Both components share identical resistance, power rating, tolerance, taper, rotation angle, and physical dimensions.

Product Status Consideration: The Honeywell 392C2250K is classified as obsolete, while the Precision Electronics RV6LAYSA254A maintains active product status. This distinction supports the RV6LAYSA254A as the preferred selection for new designs and ongoing procurement.

Compliance Status: Both parts maintain RoHS compliance (Honeywell RoHS Compliant; Precision Electronics ROHS3 Compliant) and REACH Unaffected status, satisfying regulatory requirements for both legacy and current applications.

Termination Interface: The primary implementation difference is termination style. The Honeywell 392C2250K uses PC pins, while the Precision Electronics RV6LAYSA254A uses solder lug termination. Circuit board layout and connection methodology must accommodate this difference during integration.

Resistive Material: The Honeywell uses conductive plastic material, while the Precision Electronics substitute uses carbon material. Both materials deliver the specified electrical performance within the stated tolerance and power rating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Precision Electronics RV6LAYSA254A directly replace the Honeywell 392C2250K in existing assemblies?

A: Electrical and mechanical compatibility is confirmed across all specified parameters. Physical installation is identical due to matching body dimensions, bushing thread, and actuator specifications. Termination style differs (PC pins versus solder lug), requiring circuit board connection method adjustment.

Q: What is the significance of the resistive material difference between conductive plastic and carbon?

A: Both materials deliver the specified 250k Ohm resistance within ±10% tolerance and support the 0.5W power rating. The material difference does not affect functional performance within the stated electrical parameters.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain RoHS compliance and REACH Unaffected status. The Honeywell carries RoHS Compliant designation, while the Precision Electronics carries ROHS3 Compliant designation. Both satisfy current regulatory requirements.

Q: Why is the Honeywell 392C2250K classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Precision Electronics RV6LAYSA254A maintains active product status, ensuring ongoing availability for procurement and supply chain continuity.

Q: What installation considerations apply to the solder lug termination of the substitute part?

A: Solder lug termination requires direct solder connection to circuit board pads or wire leads. This differs from PC pin termination, which typically uses through-hole or press-fit mounting. Verify circuit board design compatibility with solder lug connection methodology.

Q: Are the rotation angle and actuator dimensions identical between both parts?

A: Yes. Both components feature 295° rotation, 0.625" (15.88mm) actuator length, and 0.125" (3.18mm) actuator diameter. Panel mounting and adjustment range are functionally equivalent.
