Substitute Part Grouping Explanation

The substitute part 172-E09-103R021 qualifies as a direct equivalent based on the following critical parameters that determine substitutability:

• Connector Type & Configuration: Both parts are 9-position D-Sub plugs with male pins
• Mounting Interface: Both feature panel mount design with identical shell size (DE/E, Size 1)
• Electrical Specifications: Both support 5A current rating and operate across -50°C to 100°C
• Termination Method: Both use solder cup termination
• Shell & Contact Materials: Both feature nickel-plated steel shells with gold-plated contacts
• Series Compatibility: Both belong to the 172-E series family

The primary difference is packaging: 172-E09-102-021 is supplied in standard packaging, while 172-E09-103R021 is supplied in tray packaging. This distinction does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both parts are manufactured by NorComp Inc. and meet identical electrical and mechanical specifications for 9-position D-Sub plug applications.
