Substitute Part Grouping Explanation

Substitution eligibility for the 172-E50-202-021 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 50
• Number of Rows: 3
• Mounting Type: Panel Mount
• Shell Size: 5 (DD, D)
• Termination: Solder Cup
• Shell Material and Finish: Steel, Nickel Plated
• Contact Finish: Gold
• Current Rating: 5A
• Operating Temperature Range: -50°C ~ 100°C
• RoHS Compliance: ROHS3 Compliant

The identified substitute part 172-E50-203R021 maintains full electrical and mechanical compatibility with the primary part number across all specified parameters. The primary distinction is packaging configuration (Tray versus standard packaging) and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both the 172-E50-202-021 and 172-E50-203R021 are active products manufactured by NorComp Inc. and maintain full compliance with ROHS3 and REACH requirements. Selection between these part numbers should be based on:

1. Packaging requirements: The 172-E50-203R021 is supplied in Tray packaging, which may be preferred for automated assembly or high-volume production environments.

2. Inventory availability: The 172-E50-202-021 has higher current stock levels (1213 units) compared to the substitute (1099 units), which may influence lead time considerations.

3. Procurement specifications: If packaging format is specified in procurement documentation, the appropriate part number must be selected accordingly.

Both parts are electrically and mechanically interchangeable for applications requiring a 50-position D-Sub receptacle connector with panel mount configuration, solder cup termination, and the specified electrical ratings.

Frequently Asked Questions (FAQ)

Q: Are the 172-E50-202-021 and 172-E50-203R021 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 5A current rating, gold contact finish, and operating temperature range of -50°C to 100°C. They are fully interchangeable in circuit applications.

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

A: The primary difference is packaging configuration. The 172-E50-203R021 is supplied in Tray packaging, while the 172-E50-202-021 uses standard packaging. The connector itself is mechanically and electrically identical.

Q: Can I use the 172-E50-203R021 as a direct replacement in existing designs?

A: Yes. The 172-E50-203R021 is a direct substitute for the 172-E50-202-021. No design modifications are required. The difference in packaging does not affect connector performance or mechanical fit.

Q: Are both parts RoHS compliant?

A: Yes. Both the 172-E50-202-021 and 172-E50-203R021 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should I specify for new designs?

A: Either part number is acceptable for new designs. Selection should be based on packaging requirements and procurement preferences. Consult with your supply chain team regarding packaging specifications and lead time requirements.
