Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 770601-2 is based on strict equivalency across the following critical parameters:

Mandatory Matching Parameters:

• Contact type: Socket
• Contact termination method: Crimp
• Wire gauge range: 22-26 AWG
• Contact finish material: Gold
• Contact finish thickness: 30.0µin (0.76µm)
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance status: Compliant

The substitute part 1375819-3 maintains identical electrical and mechanical specifications across all critical parameters. The primary distinction is the product status transition from obsolete to active, with the substitute belonging to the CST-100 II series evolution. Both components are manufactured by TE Connectivity AMP Connectors and share the same ECCN and HTSUS classifications.
