Substitute Part Grouping Explanation

The substitute part 172-E50-103R021 is functionally equivalent to the main part based on the following critical parameters that determine substitutability:

  • Connector Type & Configuration: Both are 50-position D-Sub plugs with male pins in a 3-row layout (shell size 5, DD/D configuration)
  • Mounting Interface: Both feature panel mount design
  • Electrical Performance: Both support 5A current rating and operate across -50°C to 100°C
  • Termination Method: Both use solder cup termination for signal applications
  • Mechanical Compatibility: Both share the same base product number (172-E50) and series designation (172-E)

The substitute part differs only in packaging (Tray vs. unspecified for main part) and includes additional series designation (M Series), but these variations do not affect functional or mechanical compatibility.

Engineering Selection Recommendations

Both the 172-E50-102-021 and 172-E50-103R021 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The substitute part 172-E50-103R021 carries an Active product status, confirming ongoing manufacturer support and availability.

Selection between these parts should be based on:

  • Inventory Availability: Main part has 1,090 units in stock; substitute has 707 units in stock
  • Packaging Requirements: Substitute part is supplied in Tray packaging, which may influence procurement and handling procedures
  • Supply Chain Continuity: Either part provides equivalent electrical and mechanical performance for panel-mount D-Sub 50-position applications

Both parts are suitable for direct substitution in applications requiring 50-position D-Sub plug connectors with solder cup termination and 5A current capacity.

Frequently Asked Questions (FAQ)

Q: Can 172-E50-103R021 be used as a direct replacement for 172-E50-102-021?

A: Yes. Both connectors share identical electrical specifications (50 positions, 5A rating, -50°C to 100°C operating range), mechanical configuration (panel mount, shell size 5), and termination method (solder cup). They are functionally interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (Tray for the substitute) and series designation (M Series added to the substitute). These do not affect connector performance or compatibility.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both 172-E50-102-021 and 172-E50-103R021 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What wire gauge is compatible with these connectors?

A: Both connectors accept 20-26 AWG wire for solder cup termination.

Q: What is the maximum current these connectors can handle?

A: Both connectors are rated for 5A continuous current.

Q: Are there any temperature limitations for these connectors?

A: Both connectors operate reliably across -50°C to 100°C, suitable for industrial and commercial applications.
