Substitute Part Grouping Explanation
Substitution eligibility for the 176381-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:
- Connector type (Plug, Center Strip Contacts)
- Number of positions (60)
- Pitch specification (0.050" / 1.27mm)
- Number of rows (2)
- Mounting type (Through Hole, Right Angle)
- Contact finish material (Gold)
- Contact finish thickness (11.8µin / 0.30µm)
- Height above board (0.335" / 8.50mm)
- Board lock feature presence
- Series designation (Free Height)
- Moisture sensitivity level (1)
The substitute part 5176381-2 meets all these criteria and is therefore classified as a direct equivalent substitute for the 176381-2.
