Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 322320003 is determined by strict equivalence across the following critical parameters:

• Output Code: BCD Complement (identical encoding required)
• Contact Rating: 0.1A @ 120VAC/28VDC (electrical performance specification)
• Read Out Range: 0 ~ 9 (functional digit range)
• Number of Sections: 2 (physical configuration)
• Actuator Type: Thumbwheel (user interface mechanism)
• Mounting Type: Panel Mount, Screw (installation method)
• Termination Style: Card Edge/Solder Pad (circuit connection)
• Panel Cutout Dimensions: Rectangular - 26.42mm x 25.91mm (mechanical fit)
• Depth Behind Flange: 36.68mm (spatial clearance requirement)

The substitute part 322310003 meets all these criteria and is available in active product status.

Parameter Comparison
