Key Parameters

Substitute Part Grouping Explanation

Substitution of the 171-050-102-011 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 50-position D-Sub plug with male pins
• Mounting Interface: Panel mount design
• Shell Size and Layout: Size 5 (DD, D) configuration
• Electrical Performance: 5A current rating, signal contact type
• Termination Method: Solder cup termination
• Environmental Compliance: ROHS3 compliance and operating temperature range of -50°C to 100°C
• Series Designation: 171 series base product number

The substitute part 171-050-103L011 maintains full equivalence across all these parameters. Packaging differences (tray versus standard packaging) do not affect functional or electrical compatibility and represent the primary distinction between the main part and its substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 171-050-102-011 and 171-050-103L011 are active product status components manufactured by NorComp Inc. and maintain full electrical and mechanical equivalence. Selection between these parts should be based on the following criteria:

Inventory Availability: The 171-050-103L011 substitute offers higher stock availability (1094 units) compared to the primary part (958 units), providing supply chain flexibility.

Packaging Consideration: The 171-050-103L011 is supplied in tray packaging, which may affect handling, storage, and assembly line integration depending on production environment requirements.

Compliance Certification: Both parts maintain ROHS3 compliance and identical environmental ratings, ensuring regulatory equivalence for applications subject to restriction of hazardous substances directives.

Functional Equivalence: No electrical or mechanical performance differences exist between the two parts. Both support 5A current rating, identical contact geometry, and equivalent operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can 171-050-103L011 be used as a direct replacement for 171-050-102-011?

A: Yes. Both parts are electrically and mechanically equivalent 50-position D-Sub plug connectors with identical pin configurations, current ratings, and termination methods. The primary difference is packaging format (tray versus standard).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: 50-position configuration, plug connector type with male pins, panel mount design, size 5 (DD, D) shell, solder cup termination, 5A current rating, and -50°C to 100°C operating temperature range.

Q: Does packaging format affect connector performance?

A: No. Packaging format (tray versus standard) is a logistics and handling consideration only. It does not affect electrical performance, mechanical fit, or functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both 171-050-102-011 and 171-050-103L011 are ROHS3 compliant and suitable for applications subject to hazardous substances restrictions.

Q: What wire gauge compatibility should be considered?

A: Both parts support 20-28 AWG wire gauge range. Wire selection should be based on application current requirements and PCB or harness design specifications.

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

A: Yes. No design modifications are required. Both connectors maintain identical mechanical interfaces, pin layouts, and electrical characteristics, enabling direct substitution in existing assemblies.
