Substitute Part Grouping Explanation

Substitution eligibility for the FX8C-140P-SV(71) is determined by strict equivalence across the following critical parameters:

• Connector Family: Both parts must belong to the FunctionMax™ FX8C series
• Position Count: Exactly 140 positions required
• Pitch Specification: 0.024" (0.60mm) pitch maintained
• Row Configuration: 2-row layout required
• Connector Type: Header with outer shroud contacts
• Mounting Method: Surface mount technology
• Contact Material: Gold plating
• Height Above Board: 0.175" (4.45mm)
• Mated Stacking Heights: 5mm and 10mm options
• Board Guide Feature: Present on both parts

The FX8C-140P-SV(91) meets all substitution criteria as a parametric equivalent within the same connector series.
