Key Parameters

Substitute Part Grouping Explanation

Substitution of the FX8C-80S-SV(91) is determined by strict equivalence across the following parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Position count and pitch (80 positions at 0.024" / 0.60mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact finish specification (Gold)
• Board guide feature presence
• Mated stacking height compatibility
• Manufacturer series compatibility (FunctionMax™ FX8C)

The substitute part FX8C-80S-SV(68) meets all these criteria and is manufactured by the same supplier within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-80S-SV(68) is the direct substitute for the FX8C-80S-SV(91). Both parts are electrically and mechanically equivalent across all specified parameters. The primary distinction is product status: FX8C-80S-SV(91) is obsolete, while FX8C-80S-SV(68) maintains active status with current manufacturing support.

The FX8C-80S-SV(68) carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs and ongoing production. The negligible difference in height above board (0.156" versus 0.155") is within standard manufacturing tolerance and does not affect functional compatibility.
