EVJ-C25F02A14 Equivalent & Substitute Parts

Part Overview

The EVJ-C25F02A14 is a 10k Ohm 2-gang logarithmic potentiometer manufactured by Panasonic Electronic Components, rated at 0.05W (1/20W) with through-hole snap-in mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVJ-C25F02A14 is determined by the following core parameters:

• Resistance Value: 10k Ohm (exact match required)
• Taper Characteristic: Logarithmic (functional requirement for audio and signal processing applications)
• Gang Configuration: 2-gang (stereo or dual-channel applications)
• Number of Turns: 1.0 (single-turn operation)
• Rotation Angle: 300° (mechanical constraint)
• Termination Style: PC Pins with Board Locks (electrical and mechanical interface)
• Tolerance: ±20% (acceptable variance specification)

The PTD902-2015F-A103 from Bourns Inc. meets all core electrical and mechanical substitution criteria. However, mounting type differs: the substitute features panel mount configuration versus the original through-hole snap-in design. This distinction requires mechanical integration assessment during component selection.

Parameter Comparison

Engineering Selection Recommendations

The PTD902-2015F-A103 qualifies as an electrical and functional equivalent based on matching resistance, taper, gang configuration, termination style, and rotation specifications. The substitute component carries active product status with RoHS3 compliance and REACH unaffected designation, supporting long-term supply chain viability.

The primary design consideration is mounting configuration: the original EVJ-C25F02A14 employs through-hole snap-in mounting, while the PTD902-2015F-A103 uses panel mount with M7 x 0.75 bushing thread. This difference requires mechanical redesign or adapter implementation depending on application context.

Power rating differential (0.025W versus 0.05W) must be evaluated against actual circuit dissipation requirements. The lower power rating of the substitute is acceptable only if circuit operating conditions remain within the 0.025W threshold.

Frequently Asked Questions (FAQ)

Q: Can the PTD902-2015F-A103 directly replace the EVJ-C25F02A14 without modification?

A: Electrical substitution is valid based on matching resistance, taper, gang count, and termination specifications. Mechanical substitution requires assessment of mounting configuration differences. The original uses through-hole snap-in mounting; the substitute uses panel mount with M7 x 0.75 bushing thread. Direct PCB mounting without mechanical adaptation is not possible.

Q: What is the significance of the power rating difference (0.05W vs. 0.025W)?

A: Power rating indicates maximum continuous dissipation capacity. The substitute's lower rating (0.025W) is acceptable only if circuit design ensures potentiometer dissipation remains below this threshold. Applications requiring the full 0.05W capacity must retain the original specification or identify alternatives with matching power ratings.

Q: Are there compliance differences between the two parts?

A: The PTD902-2015F-A103 carries RoHS3 compliance and REACH unaffected status. The EVJ-C25F02A14 specifications do not include these certifications. If regulatory compliance is required, the Bourns substitute meets current environmental standards.

Q: What does "2-gang logarithmic" mean in practical application?

A: 2-gang configuration provides two independent potentiometer elements mechanically coupled to a single shaft, enabling synchronized dual-channel control. Logarithmic taper provides non-linear resistance change, typically used in audio applications where perceived volume follows logarithmic response curves.

Q: How do actuator dimensions affect substitution?

A: Actuator length differs (0.689" original vs. 0.591" substitute). Actuator diameter remains identical (0.236"). Length difference may affect knob clearance and mechanical fit within enclosures. Verify available space before selection.
