Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0736313001 is determined by the following critical parameters:

• Connector Position Count: 50 positions (fixed requirement)
• Row Configuration: 2 rows (fixed requirement)
• Connector Type: Receptacle with female sockets (fixed requirement)
• Mounting Method: Through-hole solder termination (fixed requirement)
• Contact Finish: Gold plating (fixed requirement)
• Flange Configuration: Latchblocks for mechanical retention (fixed requirement)
• Compliance Standards: ROHS3 compliance and MSL 1 rating (fixed requirement)

The TE Connectivity AMP Connectors 5749721-5 meets all these critical parameters as a direct substitute. Both connectors maintain identical electrical and mechanical interfaces for SCSI D-Sub applications, with equivalent contact configurations and termination methods.
