Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8-40P-SV(71) is determined by strict equivalence across the following critical parameters:

• Number of Positions: 40
• Pitch: 0.024" (0.60mm)
• Number of Rows: 2
• Connector Type: Header, Outer Shroud Contacts
• Mounting Type: Surface Mount
• Contact Finish: Gold
• Height Above Board: 0.112" (2.85mm)
• Mated Stacking Height: 3mm
• Features: Board Guide
• Series: FunctionMax™ FX8

The FX8-40P-SV(91) meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical and mechanical specifications, allowing direct substitution in applications where the FX8-40P-SV(71) is specified.
