Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector socket contacts is determined by strict equivalence across the following critical parameters:

Substitution Criteria:

• Identical base product number (640748)
• Matching pin or socket configuration (Socket)
• Identical contact termination method (Crimp)
• Identical wire gauge specification (14-18 AWG)
• Equivalent or superior RoHS compliance status
• Identical or lower moisture sensitivity level

The substitute part 640748-7 meets all substitution criteria. Both parts share the same base product number, socket type, crimp termination, and wire gauge specification. The substitute maintains ROHS3 compliance and MSL 1 rating, ensuring functional and regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations
