Key Parameters

Substitute Part Grouping Explanation

Substitution of the EVU-E2KFK4D54 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 50k Ohm (exact match required)
• Power Rating: 0.05W / 1/20W (exact match required)
• Taper Type: Logarithmic (exact match required)
• Number of Gangs: 1 (exact match required)
• Number of Turns: 1.0 (exact match required)
• Mounting Configuration: Through Hole, Snap In (exact match required)
• Termination: PC Pins with Board Locks (exact match required)
• Adjustment Method: Side Adjustment (exact match required)
• Actuator Type: Flatted (exact match required)
• Actuator Diameter: 0.236" / 6.00mm (exact match required)

The PTV09A-2020F-A503 from Bourns Inc. meets all these critical parameters and qualifies as a direct functional equivalent.

Engineering Selection Recommendations

The PTV09A-2020F-A503 is the qualified substitute for the obsolete EVU-E2KFK4D54. Selection is based on the following factors:

Product Status: The EVU-E2KFK4D54 is obsolete. The PTV09A-2020F-A503 is active and in production, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The PTV09A-2020F-A503 carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both components are classified as EAR99 for export control purposes.

Functional Equivalence: All critical electrical and mechanical parameters match exactly, including resistance value, power rating, taper type, mounting configuration, and termination style.

Minor Parameter Variations: The substitute exhibits minor differences in rotation angle (280° vs. 300°), body dimensions (11.00mm vs. 12.50mm width), and actuator length (20.00mm vs. 17.50mm). These variations are within acceptable tolerances for potentiometer applications and do not affect electrical performance or functional compatibility in standard circuit designs.

Inventory Availability: The PTV09A-2020F-A503 is currently in stock with 1962 units available, compared to 1045 units of the obsolete EVU-E2KFK4D54.

Frequently Asked Questions (FAQ)

Q: Can the PTV09A-2020F-A503 be used as a direct replacement for the EVU-E2KFK4D54?

A: Yes. Both components share identical electrical specifications (50k Ohm, 0.05W, logarithmic taper, 1 gang, 1 turn) and mechanical configurations (through-hole snap-in mounting, PC pin termination with board locks, side adjustment, flatted actuator). The minor differences in body size and actuator length do not prevent direct substitution in standard applications.

Q: What are the differences between these two potentiometers?

A: The primary differences are: (1) Rotation angle—EVU-E2KFK4D54 rotates 300° while PTV09A-2020F-A503 rotates 280°; (2) Body width—EVU-E2KFK4D54 is 12.50mm wide while PTV09A-2020F-A503 is 11.00mm wide; (3) Actuator length—EVU-E2KFK4D54 has a 17.50mm actuator while PTV09A-2020F-A503 has a 20.00mm actuator; (4) Resistive material—PTV09A-2020F-A503 specifies carbon construction while the EVU-E2KFK4D54 does not specify material; (5) Product status—EVU-E2KFK4D54 is obsolete while PTV09A-2020F-A503 is active.

Q: Will the different actuator length affect my application?

A: The PTV09A-2020F-A503 has a 2.5mm longer actuator (20.00mm vs. 17.50mm). This difference may affect panel mounting depth or knob clearance. Verify that your mechanical assembly accommodates the longer actuator before implementation.

Q: Are there any compliance or regulatory differences?

A: The PTV09A-2020F-A503 carries RoHS3 compliance and REACH unaffected status, meeting current environmental regulations. The EVU-E2KFK4D54 does not specify these certifications. Both are EAR99 classified for export control.

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

A: The EVU-E2KFK4D54 provides 300° of rotation while the PTV09A-2020F-A503 provides 280°. This 20° difference may affect the resolution or adjustment range in applications requiring precise control across the full rotation span. Evaluate your circuit's sensitivity to this parameter.

Q: Is the carbon resistive material in the PTV09A-2020F-A503 compatible with my application?

A: Carbon potentiometers are standard in audio and general-purpose applications. The carbon construction in the PTV09A-2020F-A503 does not affect electrical performance for the specified 50k Ohm, 0.05W rating. Confirm compatibility with your specific application requirements.

Q: Can I use the smaller body size of the PTV09A-2020F-A503 as an advantage?

A: Yes. The PTV09A-2020F-A503 is 1.50mm narrower (11.00mm vs. 12.50mm), which may provide space savings in compact designs. Verify that the longer actuator does not create clearance issues in your mechanical layout.
