Electrical Equivalence:

• Resistance: 1k Ohm (identical)
• Power Rating: 2W (identical)
• Tolerance: ±10% (identical)
• Taper: Linear (identical)
• Number of Gangs: 1 (identical)

Mechanical Equivalence:

• Termination Style: Solder Lug (identical)
• Mounting Type: Panel Mount (identical)
• Bushing Thread: 3/8-32 (identical)
• Actuator Type: Slotted (identical)
• Actuator Length: 0.625" / 15.88mm (identical)
• Actuator Diameter: 0.250" / 6.35mm (identical)

Functional Differences: The primary difference is resistive material technology: the main part uses conductive plastic while the substitute uses Cermet. Both materials are established technologies for potentiometer applications and deliver equivalent functional performance within the specified electrical parameters. The substitute exhibits a rotation angle of 280° compared to the main part's 312°, representing a minor mechanical variation that does not affect electrical substitutability.
