Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 172-050-282-021 are qualified based on strict equivalence across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count and row configuration (50 positions, 3 rows)
• Shell size designation (5 / DD, D)
• Mounting configuration (Panel Mount, Through Hole)
• Termination method (Solder)
• Material specifications (Steel shell with nickel plating; Brass contacts with gold flash)
• Electrical performance (5A current rating; -50°C to 125°C operating range)
• Compliance certifications (ROHS3 Compliant)

The substitute part 172-050-283L021 meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.
