Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 120790-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle, Female Sockets)
• Number of positions (100)
• Pitch specification (0.098" / 2.50mm)
• Current rating (1.15A)
• Voltage rating (250V)
• Operating temperature range (-65°C to 105°C)
• Contact finish and thickness (Gold, 30.0µin)

Mechanical Compatibility Parameters:

• Connector style (Dual Beam, Center)
• Termination method (Press-Fit)
• Through-hole configuration
• Right-angle orientation
• Series family (Z-PACK HS3)

Functional Compatibility Parameters:

• Backplane connector usage classification
• Material flammability rating (UL94 V-0)

The substitute part 5120790-1 maintains equivalence across all electrical and functional parameters. The primary distinction is the mounting configuration: the substitute employs board edge mounting in addition to through-hole capability, whereas the main part specifies PCB mounting. Both parts operate within identical electrical and thermal specifications.
