Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 172-E50-101-021 are identified based on strict electrical and mechanical parameter alignment within the 172-E series. The following parameters determine substitution eligibility:

• Connector Type: Plug, Male Pins
• Number of Positions: 50
• Number of Rows: 3
• Mounting Type: Panel Mount
• Shell Size, Connector Layout: 5 (DD, D)
• Termination: Solder Cup
• Current Rating: 5A
• Operating Temperature Range: -50°C ~ 100°C
• Dielectric Material: Polybutylene Terephthalate (PBT)
• Wire Gauge: 20-26 AWG
• Contact Material: Brass
• Material Flammability Rating: UL94 V-0

Two substitute parts meet these criteria: 172-E50-101R021 and 172-E50-103R021. Both maintain identical electrical and mechanical specifications while differing in shell material finish and product status.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 172-E50-101-021 and its substitutes depends on product status and regulatory compliance requirements:

172-E50-101-021 and 172-E50-101R021 share identical specifications with yellow chromate plated steel shells and RoHS non-compliant status. The 172-E50-101R021 is marked as obsolete, making the 172-E50-101-021 the preferred choice for new designs requiring this specific finish.

172-E50-103R021 is the only active substitute with ROHS3 compliance. It differs from the primary part only in shell material finish, featuring nickel plating instead of yellow chromate plating. This part is suitable for applications requiring RoHS3 compliance and nickel-plated connector shells.

For applications without RoHS compliance requirements and requiring yellow chromate plated shells, the 172-E50-101-021 remains the primary selection. For RoHS3-compliant designs, the 172-E50-103R021 is the appropriate substitute.

Frequently Asked Questions (FAQ)

Q: Can 172-E50-101R021 be used as a direct replacement for 172-E50-101-021?

A: Electrically and mechanically, yes. Both parts are identical in connector type, pin count, mounting configuration, and electrical ratings. However, 172-E50-101R021 is marked as obsolete. The 172-E50-101-021 is the active equivalent and should be prioritized for new designs.

Q: What is the difference between 172-E50-101-021 and 172-E50-103R021?

A: The primary difference is shell material finish. The 172-E50-101-021 features a yellow chromate plated steel shell and is RoHS non-compliant. The 172-E50-103R021 features a nickel plated steel shell and is ROHS3 compliant. All other electrical and mechanical parameters are identical.

Q: Which substitute should I use for a RoHS3-compliant application?

A: The 172-E50-103R021 is the only substitute with ROHS3 compliance. It maintains all electrical and mechanical specifications of the primary part while meeting RoHS3 requirements.

Q: Are there packaging differences between these parts?

A: The 172-E50-101-021 packaging is not specified in available data. Both 172-E50-101R021 and 172-E50-103R021 are supplied in tray packaging.

Q: Do all three parts support the same wire gauge and termination method?

A: Yes. All three parts support 20-26 AWG wire gauge and solder cup termination, ensuring compatibility in assembly processes.
