EVU-E2AF25D24 Equivalent & Substitute Parts

Part Overview

The EVU-E2AF25D24 is a 20k Ohm 1/20W logarithmic potentiometer manufactured by Panasonic Electronic Components. This through-hole, snap-in mounted component features a flatted actuator and PC pin termination with board locks. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and redesign applications where this component is specified in legacy circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete EVU-E2AF25D24 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20k Ohm
• Power rating: 0.05W (1/20W)
• Taper characteristic: Logarithmic
• Gang configuration: 1 Gang
• Termination: PC Pins with Board Locks
• Mounting: Through Hole, Snap In
• Actuator: Flatted type
• Adjustment mechanism: Side Adjustment
• Tolerance: ±20%

The PTV09A-2020F-A203 from Bourns Inc. meets all these core electrical and mechanical requirements, establishing it as a direct functional equivalent for the obsolete Panasonic component.

Parameter Comparison

Engineering Selection Recommendations

The PTV09A-2020F-A203 is the qualified substitute for the obsolete EVU-E2AF25D24. Selection is based on:

• Full electrical equivalence across resistance, power rating, taper, and tolerance specifications
• Identical mechanical interface: through-hole snap-in mounting with PC pin termination and board locks
• Matching actuator configuration: flatted type with side adjustment
• Active product status with current manufacturing availability
• ROHS3 compliance, ensuring alignment with modern environmental and regulatory standards

Minor dimensional variations exist in actuator length (20.00mm vs. 18.20mm) and rotation angle (280° vs. 300°), which are within acceptable tolerances for standard potentiometer applications and do not affect functional substitution in typical audio and control circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the PTV09A-2020F-A203 directly replace the EVU-E2AF25D24 in existing designs?

A: Yes. Both components share identical electrical specifications (20k Ohm, 0.05W, logarithmic taper, ±20% tolerance) and mechanical interfaces (through-hole snap-in mounting, PC pins with board locks, flatted actuator, side adjustment). The minor differences in actuator length and rotation angle do not affect functional compatibility in standard applications.

Q: What are the key differences between these two potentiometers?

A: The primary differences are actuator length (EVU-E2AF25D24: 18.20mm; PTV09A-2020F-A203: 20.00mm), rotation angle (EVU-E2AF25D24: 300°; PTV09A-2020F-A203: 280°), and resistive material (EVU-E2AF25D24: unspecified; PTV09A-2020F-A203: carbon). The Bourns component is ROHS3 compliant and currently in active production.

Q: Are there packaging considerations when substituting these parts?

A: The EVU-E2AF25D24 is supplied in standard packaging, while the PTV09A-2020F-A203 is supplied in trays. Both use identical PC pin termination and board lock mounting, requiring no PCB redesign. Physical footprint differences are minimal and do not require layout modifications for standard applications.

Q: Why is the EVU-E2AF25D24 obsolete?

A: The component has been discontinued by Panasonic Electronic Components. The PTV09A-2020F-A203 from Bourns Inc. provides full functional equivalence with the added benefit of active production status and modern compliance certifications.

Q: What compliance standards apply to the substitute part?

A: The PTV09A-2020F-A203 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in industrial and consumer applications.
