Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish substitutability for the 177983-3:

Critical Matching Parameters:

• Connector type (Receptacle, Outer Shroud Contacts)
• Number of positions (80)
• Pitch specification (0.031" / 0.80mm)
• Number of rows (2)
• Mounting technology (Surface Mount)
• Contact finish material and thickness (Gold, 8.00µin)
• Height above board (0.148" / 3.75mm)
• Mated stacking height range (5mm, 6mm, 7mm, 8mm)
• Board guide feature presence

The substitute part 5177983-3 maintains complete electrical and mechanical compatibility with the original 177983-3 across all specified parameters. The primary distinction is product status and regulatory compliance, not functional or dimensional characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5177983-3 serves as the direct active equivalent to the obsolete 177983-3. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications across all functional parameters.
