Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0875520681 is determined by the following critical parameters:

• Number of Positions: 68 positions (fixed requirement)
• Contact Spacing: .050" (fixed requirement)
• Connector Type: Receptacle (fixed requirement)
• Mounting Type: Right Angle (fixed requirement)
• Connector Category: D-Sub, D-Shaped Connectors (fixed requirement)
• Application Type: Board to Board (fixed requirement)

The TE Connectivity AMP Connectors part 1734037-7 satisfies all these parameters. It is an active product from the CHAMP .050 I series, providing direct functional equivalence to the obsolete Molex connector while offering improved compliance status and current manufacturing availability.
