FX10A-168S-SV(21) from Hirose Electric Co Ltd is a rectangular connector intended for board-level interconnect use in systems that demand high contact density and reliable signal routing. Engineers typically evaluate parts in this class for embedded hardware, industrial electronics, communications equipment, test platforms, and compact electronic assemblies where connector selection affects maintainability and long-term sourcing. As a Hirose component, it is positioned within a well-known connector portfolio often considered for quality-focused designs and production programs. The current lifecycle status for FX10A-168S-SV(21) is information not available, so teams should confirm availability and long-term support directly with Hirose or an authorized distributor before locking it into a new design. RoHS compliance information is also not available from the provided data. For compliance-sensitive applications, engineers and procurement teams should verify the latest environmental declarations, datasheet details, and manufacturer documentation before qualification or purchase.
