EVJ-C31F25B24 Equivalent & Substitute Parts

Part Overview

The EVJ-C31F25B24 is a 20k Ohm 2 Gang linear potentiometer manufactured by Panasonic Electronic Components, rated at 0.05W (1/20W) power dissipation. This component features through-hole, snap-in mounting with PC pins and board locks, designed for side adjustment applications with a 300° rotation and 1.0 turn specification. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active product lines to maintain design continuity and ensure component availability for new production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVJ-C31F25B24 is determined by strict alignment of the following critical parameters: resistance value (20k Ohm), tolerance (±20%), power rating (0.05W/1/20W), taper type (linear), number of turns (1.0), rotation angle (300°), termination style (PC Pins, Board Locks), and adjustment type (side adjustment).

The substitute parts identified from the provided list are evaluated based on these core electrical and mechanical specifications. Mounting type differences and gang configuration variations are noted as design considerations that may affect direct interchangeability depending on circuit board layout and application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Bourns Inc. and maintain active product status, ensuring ongoing availability and supply chain continuity.

PTD902-2215K-B203 matches all core electrical parameters (20k Ohm, ±20% tolerance, 0.05W power rating, linear taper, 1.0 turn, 300° rotation, 2 gangs) and maintains identical termination and adjustment specifications. The primary design consideration is the panel mount configuration versus the through-hole snap-in mounting of the original part. This substitute is suitable for applications where panel-mount installation is compatible with the circuit board design.

PTV111-2420A-B203 matches all core electrical parameters and mounting type (through-hole, snap-in) but differs in gang configuration, providing 1 gang instead of 2 gangs. This substitute is applicable only to designs where single-gang operation is functionally equivalent to the dual-gang original specification. The through-hole snap-in mounting provides direct mechanical compatibility with the original part's installation method.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. Selection between these alternatives depends on specific circuit board layout requirements and functional gang requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can PTD902-2215K-B203 directly replace EVJ-C31F25B24 on the same circuit board?

A: PTD902-2215K-B203 matches all electrical specifications and gang configuration but uses panel mount rather than through-hole snap-in mounting. Direct board-level substitution requires mechanical compatibility assessment of the mounting interface.

Q: Is PTV111-2420A-B203 suitable for applications requiring dual-gang operation?

A: No. PTV111-2420A-B203 provides single-gang configuration, whereas EVJ-C31F25B24 is dual-gang. This substitute is applicable only to designs where single-gang potentiometer operation meets functional requirements.

Q: What are the key electrical parameters that must match for substitution?

A: Resistance value (20k Ohm), tolerance (±20%), power rating (0.05W), taper type (linear), number of turns (1.0), rotation angle (300°), and termination style (PC Pins, Board Locks) are the critical parameters determining substitution eligibility.

Q: Are both substitute parts compliant with current regulatory standards?

A: Yes. Both PTD902-2215K-B203 and PTV111-2420A-B203 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the primary difference between the two substitute options?

A: PTD902-2215K-B203 maintains dual-gang configuration but uses panel mount installation. PTV111-2420A-B203 maintains through-hole snap-in mounting but provides single-gang configuration. Selection depends on whether the application requires dual-gang functionality and the mechanical mounting method compatible with the circuit board design.
