Key Parameters

Substitute Part Grouping Explanation

The FX6-50P-0.8SV(71) qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Configuration: Both parts are 50-position headers with outer shroud contacts in a 2-row arrangement
• Electrical Interface: Identical pitch of 0.031" (0.80mm) ensures mechanical and electrical compatibility
• Physical Dimensions: Matching height above board (0.197" / 5.00mm) and mated stacking heights (5mm, 7mm) confirm PCB footprint compatibility
• Mounting Technology: Both utilize surface mount technology with board guide features
• Contact Material: Gold plating on both parts ensures equivalent electrical performance and reliability
• Series Continuity: Both belong to the FX6 series, confirming design family compatibility

The substitution is based strictly on matching electrical and mechanical parameters that determine functional interchangeability in the application circuit.

Parameter Comparison
