Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 172-050-112-021 is determined by strict alignment of the following parameters:

• Connector category: D-Sub, D-Shaped Connectors
• Position count: 50 positions
• Connector gender: Male pins (plug configuration)
• Mount style: Panel mount
• Termination method: Solder
• Manufacturer: NorComp Inc.

The identified substitute part 172-E50-112-021 maintains equivalence across all critical parameters, differing only in series designation (172-E versus 172). Both parts function identically within applications requiring 50-position D-Sub plug connectors with panel-mount solder termination.

Parameter Comparison

Engineering Selection Recommendations

Both the 172-050-112-021 and 172-E50-112-021 are qualified for direct substitution in applications requiring 50-position D-Sub plug connectors with panel-mount solder termination. Selection between these parts should be based on inventory availability and procurement lead time requirements. The 172-E50-112-021 maintains higher stock levels (1330 pieces) compared to the primary part (1037 pieces), supporting expedited procurement scenarios. Both parts are manufactured by NorComp Inc. and carry equivalent functional specifications for D-Sub connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 172-E50-112-021 directly replace the 172-050-112-021 in existing designs?

A: Yes. Both parts are 50-position D-Sub plug connectors with identical electrical and mechanical specifications. The series designation difference (172 versus 172-E) does not affect functional compatibility. Direct substitution is supported for panel-mount solder termination applications.

Q: What are the critical parameters that define substitution eligibility for this connector?

A: Substitution is valid when the following parameters match: connector category (D-Sub, D-Shaped Connectors), position count (50), connector gender (male pins), mount style (panel mount), termination method (solder), and manufacturer (NorComp Inc.).

Q: Are there packaging differences between the 172-050-112-021 and 172-E50-112-021?

A: Packaging information is not provided in the technical specifications for either part. Consult the manufacturer's datasheet or contact NorComp Inc. directly for packaging and shipping specifications.

Q: Which part should be selected for new procurement?

A: Selection should be based on current inventory availability and project lead time requirements. The 172-E50-112-021 offers higher stock availability (1330 pieces) and may support faster delivery timelines.
