Substitute Part Grouping Explanation

Substitution eligibility for the 120637-1 is determined by strict equivalence across the following critical parameters:

• Connector Type and Configuration: Receptacle with female sockets
• Position Count: 144 positions
• Pitch Specification: 0.079" (2.00mm) board edge spacing
• Row Configuration: 12 rows
• Mounting and Termination: Board edge, through hole, right angle orientation with press-fit termination
• Series Classification: Z-PACK series designation
• Manufacturer: TE Connectivity AMP Connectors

The substitute part 5120637-1 meets all these criteria and is therefore classified as a direct equivalent. Substitution is valid when these parameters remain constant across the application requirement.
