Substitute Part Grouping Explanation

Substitution of the DF9-23P-1V(20) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header with center strip contacts, dual-row arrangement
• Electrical Specifications: 23-position count, 1.00mm pitch spacing
• Mechanical Compatibility: Surface mount mounting type, 4.3mm mated stacking height, 3.30mm height above board
• Contact Properties: Tin finish material
• Functional Features: Board guide and solder retention capabilities

The DF9-23P-1V(32) meets all substitution criteria as a direct equivalent within the DF9 series, maintaining identical electrical and mechanical parameters while offering active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The DF9-23P-1V(32) serves as the direct functional equivalent to the DF9-23P-1V(20). Selection between these parts is determined by compliance and product lifecycle requirements:

DF9-23P-1V(32) is the preferred selection for new designs and ongoing procurement due to active product status and RoHS compliance certification. This part maintains full electrical and mechanical compatibility while offering improved regulatory alignment and supply chain continuity.

DF9-23P-1V(20) is obsolete and should not be selected for new applications. Existing designs utilizing this part number should transition to DF9-23P-1V(32) to ensure long-term component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are DF9-23P-1V(20) and DF9-23P-1V(32) electrically interchangeable?
