Honeywell 308N2500 Potentiometer - Equivalent & Substitute Parts

Part Overview

The Honeywell 308N2500 is a 2.5k 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 functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The 1-gang linear taper configuration with 295° rotation and 1/4-32 bushing thread provides standard panel mounting functionality for industrial and consumer applications requiring precision resistance adjustment.

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 308N2500 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.5k Ohm
• Tolerance: ±10%
• Power rating: 0.5W, 1/2W
• Taper type: Linear
• Number of gangs: 1
• Number of turns: 1.0
• Rotation angle: 295°
• Mounting type: Panel Mount
• Bushing thread: 1/4-32
• Actuator diameter: 0.125" (3.18mm)

Allowable Variations:

• Resistive material: Conductive Plastic or Carbon film
• Termination style: Solder Hook or Solder Lug
• Body shape: Square or Round (within dimensional tolerance)
• Actuator length: Minor variations acceptable if panel clearance permits

Engineering Selection Recommendations

Primary Substitute: Precision Electronics Corporation RV6NAYSD252A

The RV6NAYSD252A is the qualified substitute for the obsolete Honeywell 308N2500. Selection rationale is based on the following engineering factors:

Electrical Equivalence: Both components provide identical resistance value (2.5k Ohm), tolerance (±10%), power rating (0.5W, 1/2W), and taper characteristic (Linear). Electrical performance in circuit applications is functionally equivalent.

Mechanical Compatibility: Panel mounting configuration, bushing thread specification (1/4-32), actuator diameter (0.125"), and rotation angle (295°) are identical. Physical installation in existing panel cutouts is compatible.

Compliance Status: The RV6NAYSD252A holds ROHS3 Compliant certification, exceeding the RoHS Compliant status of the obsolete 308N2500. This component satisfies current environmental and regulatory requirements for new designs and system updates.

Material Consideration: The substitute uses carbon resistive material versus the original conductive plastic. Both materials are standard in potentiometer design and provide equivalent functional performance for linear adjustment applications. Carbon film potentiometers are widely used in industrial applications and offer established reliability.

Termination Difference: The RV6NAYSD252A uses solder lug termination instead of solder hook. Both termination styles are compatible with standard PCB assembly processes. Solder lug termination provides equivalent electrical connection reliability.

Availability: The RV6NAYSD252A is classified as Active product status with 926 pieces in stock, ensuring supply continuity for replacement and new production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Precision Electronics RV6NAYSD252A directly replace the Honeywell 308N2500 in existing assemblies?

A: Yes. The RV6NAYSD252A meets all critical electrical and mechanical parameters. Identical resistance, tolerance, power rating, taper, rotation angle, and panel mounting specifications ensure direct functional replacement. The component fits the same 1/4-32 bushing thread and operates within the same electrical performance envelope.

Q: What is the difference between conductive plastic and carbon resistive materials in potentiometers?

A: Both materials provide linear resistance adjustment and are suitable for general-purpose potentiometer applications. Conductive plastic offers smoother operation and lower noise characteristics. Carbon film provides established reliability in industrial environments. For the 308N2500 application, both materials deliver equivalent functional performance.

Q: Are solder hook and solder lug terminations interchangeable?

A: Both termination styles provide equivalent electrical connection to PCB or wiring. Solder hook termination uses a hook-shaped lead for insertion into PCB holes. Solder lug termination uses a flat tab for direct soldering. Assembly process compatibility depends on existing PCB design. Standard PCB assembly equipment accommodates both termination styles.

Q: Does the round body shape of the RV6NAYSD252A affect panel mounting compatibility?

A: No. The round body diameter (0.510" / 12.95mm) is dimensionally compatible with the square body (0.500" x 0.500" / 12.70mm) of the original component. Both fit standard 1/4-32 bushing thread panel cutouts. Panel clearance and mechanical fit are equivalent.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: ROHS3 represents the current version of the Restriction of Hazardous Substances directive with updated substance restrictions. RoHS Compliant indicates compliance with earlier RoHS standards. ROHS3 Compliant status of the RV6NAYSD252A satisfies current environmental regulations and is suitable for new product designs and system updates.

Q: Are there any electrical performance differences between the two potentiometers?

A: No. Both components provide identical electrical specifications: 2.5k Ohm resistance, ±10% tolerance, 0.5W/1/2W power rating, and linear taper. Electrical performance in circuit applications is equivalent.

Q: What packaging format is the RV6NAYSD252A supplied in?

A: The RV6NAYSD252A is supplied in Bulk packaging. The original 308N2500 packaging format is not specified in available documentation. Bulk packaging is standard for component procurement and is compatible with standard assembly processes.
