Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 171-050-102-001 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type: Plug with Male Pins
• Number of Positions: 50
• Number of Rows: 3
• Shell Size: 5 (DD, D)
• Mounting Type: Panel Mount
• Termination Method: Solder Cup
• Current Rating: 5A
• Operating Temperature Range: -50°C ~ 100°C
• Dielectric Material: Polybutylene Terephthalate (PBT), Glass Filled
• Contact Material: Copper Alloy

The substitute parts 171-050-102L001 and 171-050-103L001 maintain identical electrical and mechanical specifications across these parameters. Variations exist only in shell material finish (tin plated versus nickel plated) and product status, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications. The primary distinction among these parts is product status and shell material finish.

The 171-050-102-001 and 171-050-103L001 are both active products, with 171-050-103L001 featuring nickel-plated steel shell construction. The 171-050-102L001 is classified as obsolete but remains functionally equivalent with tin-plated steel shell finish.

Selection should prioritize active product status for long-term supply chain stability. The 171-050-103L001 offers the advantage of active product status combined with nickel plating, which provides enhanced corrosion resistance compared to tin plating. The 171-050-102-001 remains a viable primary choice with current availability and tin-plated finish.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All three parts maintain identical electrical specifications including 50-position configuration, 5A current rating, and operating temperature range of -50°C to 100°C.

Q: What is the difference between tin-plated and nickel-plated shell finishes? A: Shell material finish affects corrosion resistance and environmental durability. Nickel plating (171-050-103L001) provides superior corrosion resistance in harsh environments. Tin plating (171-050-102-001 and 171-050-102L001) is suitable for standard industrial applications.

Q: Can I use the obsolete part 171-050-102L001 as a substitute? A: The 171-050-102L001 is functionally equivalent and maintains all critical electrical and mechanical parameters. However, active product status (171-050-102-001 or 171-050-103L001) is recommended for new designs and long-term production requirements.

Q: What packaging is available for these parts? A: The 171-050-102-001 is supplied in standard packaging. Substitute parts 171-050-102L001 and 171-050-103L001 are supplied in tray packaging.

Q: Are all parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
