Key Parameters

Substitute Part Grouping Explanation

Substitution for the 171-050-102-021 is based on strict equivalence across the following critical parameters:

• Connector Type & Configuration: Plug with male pins, 50-position layout
• Mounting Interface: Panel mount design
• Electrical Interface: Solder cup termination
• Physical Form Factor: Shell size 5 (DD, D) D-Sub configuration
• Manufacturer Consistency: NorComp Inc. series 171 family

The substitute part 171-050-103L021 maintains identical electrical and mechanical specifications across all these parameters. The primary difference is packaging format (Tray vs. standard packaging) and inventory availability, which do not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 171-050-102-021 and 171-050-103L021 are functionally equivalent for D-Sub connector applications requiring 50-position plug configuration with panel mount and solder cup termination. Selection between these parts should be based on:

• Packaging Requirements: The 171-050-103L021 is supplied in Tray packaging, which may be preferred for automated assembly or high-volume production environments.
• Inventory Availability: The 171-050-103L021 offers higher stock availability (900 units) compared to the 171-050-102-021 (743 units).
• Compliance Status: Both parts maintain ROHS3 compliance and are suitable for applications requiring regulatory adherence.
• Product Status: The 171-050-103L021 is marked as Active, ensuring continued manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can 171-050-103L021 be used as a direct replacement for 171-050-102-021?

A: Yes. Both connectors are electrically and mechanically identical across all critical parameters including pin count, shell size, termination type, and electrical ratings. The only difference is packaging format.

Q: What is the significance of the packaging difference between these parts?

A: The 171-050-102-021 uses standard packaging while 171-050-103L021 uses Tray packaging. This affects handling, storage, and integration into automated assembly processes but does not impact connector performance or compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 171-050-102-021 and 171-050-103L021 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What are the key electrical specifications that define substitution compatibility?

A: The 50-position configuration, 5A current rating, gold-plated contacts, and -50°C to 100°C operating temperature range are the primary electrical specifications that determine substitution compatibility within this connector family.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The identical shell size (5/DD, D), mounting type (panel mount), and termination method (solder cup) ensure mechanical and electrical interchangeability in existing PCB layouts and panel designs.
