Honeywell 308N10K Potentiometer - Equivalent & Substitute Parts

Part Overview

The Honeywell 308N10K is a 10k Ohm, 1/2W linear panel mount potentiometer with conductive plastic resistive material and solder hook termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The 308N series features a 1-gang configuration with 295° rotation and 1/4-32 bushing thread mounting for standard panel integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 308N10K is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 10k Ohm
• Power rating: 0.5W or 1/2W minimum
• Taper: Linear
• Number of gangs: 1
• Resistive material: Conductive Plastic
• Mounting type: Panel Mount
• Bushing thread: 1/4-32

Secondary Compatibility Factors:

• Rotation angle (295° minimum acceptable)
• Actuator dimensions (0.750" length, 0.125" diameter)
• Body size (square or rectangular face within tolerance)
• Termination style (solder hook or solder lug acceptable for circuit integration)

The Bourns 53CAD-E24-B15L meets all primary matching criteria and maintains functional equivalence despite minor variations in tolerance and body dimensions.

Engineering Selection Recommendations

Primary Substitute: Bourns 53CAD-E24-B15L

The Bourns 53CAD-E24-B15L is the designated equivalent for the obsolete Honeywell 308N10K. This substitute maintains functional equivalence across all critical electrical and mechanical parameters:

• Identical 10k Ohm resistance and 1/2W power rating
• Matching linear taper and single-gang configuration
• Conductive plastic resistive material with identical actuator geometry
• Compatible 1/4-32 panel mount bushing thread
• Active product status ensures ongoing availability and supply chain continuity

Tolerance Consideration: The substitute exhibits ±20% tolerance compared to the original ±10% specification. Applications requiring tighter resistance tolerance should evaluate circuit-level impact before substitution.

Rotation Specification: The substitute provides 290° rotation versus the original 295°. This 5° difference is negligible for standard potentiometer applications and does not affect functional performance in typical audio, instrumentation, or control circuits.

Termination Difference: The substitute uses solder lug termination instead of solder hook. Both termination methods are compatible with standard PCB and panel wiring practices. Solder lug termination may provide improved mechanical stability in high-vibration environments.

Compliance Status: Both components maintain RoHS compliance. The substitute carries ROHS3 certification and REACH compliance status, meeting current regulatory requirements for European and international markets.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 53CAD-E24-B15L directly replace the Honeywell 308N10K without circuit modification?

A: Yes. The substitute maintains identical electrical specifications (10k Ohm, 1/2W, linear taper) and mechanical compatibility (panel mount, 1/4-32 bushing, matching actuator dimensions). Termination style differs (solder lug vs. solder hook), but both are standard connection methods. No circuit modification is required.

Q: What is the impact of the ±20% tolerance on the substitute compared to ±10% on the original?

A: The wider tolerance on the substitute means resistance values may deviate up to ±20% from the nominal 10k Ohm specification. For applications where precise resistance is critical, measure the substitute component before installation or implement circuit-level compensation if necessary.

Q: Does the 5° difference in rotation (290° vs. 295°) affect performance?

A: No. The 5° difference is negligible for standard potentiometer applications. Both rotation specifications provide full functional range for audio mixing, instrumentation adjustment, and control circuits. This parameter does not impact electrical performance.

Q: Are there any packaging or inventory differences between these parts?

A: The original Honeywell 308N10K is obsolete with limited remaining inventory. The Bourns 53CAD-E24-B15L is an active product with current production and established supply chain availability. The substitute is packaged in bulk format, suitable for production environments.

Q: What is the difference between solder hook and solder lug termination?

A: Solder hook termination features a hook-shaped lead for wire wrapping or direct solder connection. Solder lug termination provides a flat lug for crimp or solder connection. Both methods are compatible with standard assembly practices. Solder lug termination may offer improved mechanical retention in applications subject to vibration or thermal cycling.

Q: Are both components RoHS compliant?

A: Yes. The Honeywell 308N10K is RoHS Compliant. The Bourns 53CAD-E24-B15L carries ROHS3 Compliant certification, meeting current and future regulatory standards. Both components are suitable for applications requiring RoHS compliance.

Q: What is the body size difference between these potentiometers?

A: The Honeywell 308N10K has a square body face (0.500" x 0.500", 12.70mm x 12.70mm). The Bourns 53CAD-E24-B15L has a rectangular body face (0.521" x 0.492", 13.25mm x 12.50mm). Both dimensions are within standard panel mount tolerances and do not affect functional compatibility.
