Equivalent & Substitute Parts for Honeywell 62JA5K Wirewound Potentiometer

Part Overview

The Honeywell 62JA5K is a 5k Ohm, 2W wirewound linear potentiometer designed for panel mount applications with a 10-turn adjustment mechanism. This component features solder lug termination and is rated for 3600° rotation with a ±5% tolerance specification. The 62JA5K is classified as obsolete, necessitating identification of active substitute components that maintain functional and mechanical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 62JA5K is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5k Ohm
• Power rating: 2W
• Taper characteristic: Linear
• Number of turns: 10
• Resistive material: Wirewound
• Termination style: Solder lug
• Mounting configuration: Panel mount
• Bushing thread specification: 3/8-32
• Single gang configuration
• Full rotation: 3600°

Both identified substitute parts—Bourns 3500S-2-502L and Bourns 3540S-1-502L—satisfy all mandatory matching parameters. These components are classified as active products with current manufacturing status, providing supply continuity for applications previously utilizing the obsolete 62JA5K.

Parameter Comparison

Engineering Selection Recommendations

Both Bourns substitute components provide functional equivalence to the obsolete Honeywell 62JA5K across all critical electrical and mechanical parameters. Selection between the two Bourns options is determined by packaging and compliance requirements:

Bourns 3500S-2-502L is supplied in bulk packaging and features a tighter tolerance specification of ±3% compared to the original ±5% tolerance. This component carries ROHS3 compliance certification and REACH affected status designation.

Bourns 3540S-1-502L is supplied in tray packaging and maintains the original ±5% tolerance specification. This component also carries ROHS3 compliance certification and REACH affected status designation. Higher inventory availability (2598 pcs) supports extended production schedules.

Both substitute parts exhibit a temperature coefficient of ±50ppm/°C, which differs from the original 62JA5K specification of ±20ppm/°C. This parameter variance does not affect substitution eligibility, as both components remain functionally compatible within the established mechanical and electrical framework.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 3500S-2-502L and 3540S-1-502L be used interchangeably with the Honeywell 62JA5K?

A: Both Bourns components satisfy all mandatory electrical and mechanical compatibility criteria for direct substitution. The primary distinction is packaging format: 3500S-2-502L is supplied in bulk, while 3540S-1-502L is supplied in tray configuration. Selection depends on procurement and assembly workflow requirements.

Q: What is the significance of the tolerance difference between the 62JA5K (±5%) and the 3500S-2-502L (±3%)?

A: The 3500S-2-502L provides tighter tolerance control, which may improve circuit performance in applications requiring higher precision. The original 62JA5K tolerance of ±5% is maintained by the 3540S-1-502L, providing direct specification alignment for applications with established tolerance requirements.

Q: How do the temperature coefficient specifications affect component selection?

A: The 62JA5K specifies ±20ppm/°C, while both Bourns substitutes specify ±50ppm/°C. Both substitute components remain functionally compatible. Applications operating across wide temperature ranges should evaluate whether the increased temperature coefficient affects circuit stability within the intended operating environment.

Q: Are there packaging considerations for high-volume assembly operations?

A: The 3540S-1-502L is supplied in tray packaging with higher inventory availability (2598 pcs), supporting extended production runs. The 3500S-2-502L is supplied in bulk packaging. Packaging selection aligns with assembly automation requirements and supply chain logistics.

Q: Do both substitute parts meet current regulatory compliance standards?

A: Both Bourns components carry ROHS3 compliance certification and REACH affected status designation, meeting current environmental and regulatory requirements. The original 62JA5K carries RoHS compliance certification. Both substitutes provide equivalent or enhanced compliance posture for new designs and ongoing production.

Q: What are the mechanical compatibility parameters for panel mount installation?

A: Both substitute components maintain the 3/8-32 bushing thread specification, identical body diameter (0.875"), and slotted actuator configuration. Actuator length differs slightly (0.813" for 3500S-2-502L and 0.812" for 3540S-1-502L versus 0.937" for the original), requiring verification of panel cutout and actuator clearance in existing mechanical assemblies.
