Substitute Part Grouping Explanation

Substitution for the 71609-326 is based on strict equivalence across the following critical parameters:

• Connector geometry: 52 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Mounting configuration: Surface mount, right-angle orientation
• Contact specification: Female socket, gold-plated mating surface
• Insulation properties: Thermoplastic glass-filled material with UL94 V-0 rating
• Mechanical interface: Board-to-board, push-pull fastening

The substitute part 71609-326LF maintains identical electrical and mechanical specifications to the main part number, with the primary distinction being product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 71609-326LF is the direct substitute for the obsolete 71609-326. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in board-to-board connector applications.

The 71609-326LF carries active product status, providing assured long-term availability and supply chain support. This part is RoHS compliant and REACH affected, meeting current regulatory requirements for new designs and production environments subject to these compliance frameworks.

Selection between these parts should be based on regulatory requirements applicable to the end application. For new designs or systems requiring RoHS compliance, the 71609-326LF is the appropriate choice. For legacy systems or applications where the original 71609-326 specification must be maintained, the substitute provides equivalent performance with updated compliance status.

Frequently Asked Questions (FAQ)

Q: Are the 71609-326 and 71609-326LF mechanically interchangeable?
