Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FX8C-80S-SV5(21) is determined by strict equivalence across the following critical 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)
• Physical dimensions (Height Above Board: 0.352" / 8.95mm; Mated Stacking Heights: 10mm, 11mm, 12mm, 14mm, 16mm)
• Board guide feature presence

The FX8C-80S-SV5(91) meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The FX8C-80S-SV5(91) is the direct substitute for the obsolete FX8C-80S-SV5(21). Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring pin-for-pin and footprint compatibility.
