Substitute Part Grouping Explanation

Substitution of the 176378-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5176378-2 maintains identical specifications for connector configuration, contact arrangement, pitch, mounting methodology, and physical dimensions. Both parts are 60-position receptacles with outer shroud contacts, 0.050" pitch spacing, two-row configuration, through-hole mounting, gold contact finish at 11.8µin thickness, and identical board heights of 0.610" above the PCB.

The primary distinction between the main part and its substitute is product status and compliance certification. The 176378-2 is classified as obsolete with RoHS non-compliant status, while the 5176378-2 is an active product with ROHS3 compliance. This substitution relationship is based on the following key parameters:

• Number of Positions: 60
• Pitch: 0.050" (1.27mm)
• Number of Rows: 2
• Connector Type: Receptacle, Outer Shroud Contacts
• Mounting Type: Through Hole
• Contact Finish: Gold
• Contact Finish Thickness: 11.8µin (0.30µm)
• Height Above Board: 0.610" (15.50mm)
• Mated Stacking Heights: 18mm
• Series: Free Height (FH)
• Features: Board Guide
