Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVU-E2AF25B24 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 20k Ohm (exact match required)
• Tolerance: ±20% (matching specification)
• Power Rating: 0.05W / 1/20W (minimum requirement)
• Taper Type: Linear (functional requirement)
• Number of Gangs: 1 (circuit configuration)
• Number of Turns: 1.0 (adjustment range)
• Mounting Configuration: Through Hole, Snap In (mechanical fit)
• Termination Style: PC Pins, Board Locks (PCB interface)
• Actuator Type: Flatted (mechanical interface)
• Actuator Diameter: 0.236" / 6.00mm (panel cutout compatibility)

The PTV09A-7020F-B203 from Bourns Inc. meets all critical electrical and mechanical parameters for direct substitution. Minor variations in body dimensions and rotation angle (280° vs. 300°) remain within acceptable tolerances for equivalent functional performance.

Parameter Comparison

Engineering Selection Recommendations

The PTV09A-7020F-B203 is the qualified substitute for the obsolete EVU-E2AF25B24. Selection is based on the following engineering criteria:

Electrical Equivalence: Both components share identical resistance (20k Ohm), tolerance (±20%), power rating (0.05W), and taper (linear), ensuring functional interchangeability in circuit applications.

Mechanical Compatibility: Mounting configuration, termination style, actuator type, and actuator diameter are identical, confirming direct PCB fit without modification.

Product Status: The Bourns component is active and in production, providing long-term supply continuity compared to the obsolete Panasonic part.

Compliance Enhancement: The PTV09A-7020F-B203 carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component procurement.

Minor Parameter Variations: The 20° difference in rotation angle (280° vs. 300°) and slight body dimension variations (11.00mm x 9.70mm vs. 11.50mm x 9.50mm) remain within acceptable engineering tolerances and do not affect functional performance or mechanical fit in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the PTV09A-7020F-B203 be used as a direct replacement for the EVU-E2AF25B24?

A: Yes. Both components meet identical specifications for resistance value, tolerance, power rating, taper type, number of gangs, number of turns, mounting configuration, termination style, and actuator dimensions. Direct substitution is supported without circuit or PCB modifications.

Q: What is the significance of the 20° rotation difference?

A: The EVU-E2AF25B24 provides 300° of rotation, while the PTV09A-7020F-B203 provides 280°. This 20° variation represents a 6.7% difference in total adjustment range. For applications requiring the full 300° range, this difference must be evaluated against specific design requirements. In most standard potentiometer applications, 280° rotation provides sufficient adjustment capability.

Q: Are there packaging differences between these components?

A: The EVU-E2AF25B24 is supplied in standard packaging, while the PTV09A-7020F-B203 is supplied in Tray packaging. Both are through-hole, snap-in components with identical PCB interface specifications. Tray packaging is standard for active production components and does not affect electrical or mechanical performance.

Q: Does the Bourns substitute meet current regulatory requirements?

A: Yes. The PTV09A-7020F-B203 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement in most jurisdictions.

Q: Are there any body dimension concerns for PCB layout?

A: Body dimensions differ slightly (11.00mm x 9.70mm for Bourns vs. 11.50mm x 9.50mm for Panasonic). These variations are within standard manufacturing tolerances and do not affect PCB cutout or mounting hole specifications. Verify panel cutout dimensions if the component is mounted through a front panel.

Q: What is the resistive material difference?

A: The EVU-E2AF25B24 uses unspecified resistive material, while the PTV09A-7020F-B203 uses carbon film. Carbon film construction is standard for linear potentiometers in this power and resistance class and provides stable performance across the specified operating range.
