Substitute Part Grouping Explanation

Substitution of the 2-179540-4 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for connector type, position count, pitch, row configuration, mounting methodology, contact material and finish, and board height. The primary substitute identified is the TE Connectivity AMP Connectors 2-5179540-4, which maintains complete parameter alignment with the original part while offering active product status and improved compliance posture.

The substitution logic is based on the following key parameters:

• Connector Type: Plug, Center Strip Contacts
• Number of Positions: 100
• Pitch: 0.050" (1.27mm)
• Number of Rows: 2
• Mounting Type: Through Hole
• Contact Finish: Gold at 30.0µin (0.76µm)
• Height Above Board: 0.275" (6.99mm)
• Series: Free Height (FH)
