Single-Position Board-to-Board Bridge, 3 A at 350 V
The Hirose DF59SN-1P-FC(21) is a single-position board-to-board adapter from the DF59SN series — a push-mount, snap-in bridge that links two PCBs without solder. Rated 3 A per circuit with a 350 V voltage rating, it carries more headroom than its compact size suggests, suited for power or signal routing across a board gap where a single connection point is all the BOM calls for. The tin-plated brass contacts and beige LCP housing handle an operating range of -35°C to 105°C, wider than many consumer-grade board-to-board interconnects, which extends its use into industrial or outdoor equipment where temperature cycling is a factor.
Push-Mount Snap-In Assembly
The push-mount, snap-in design means no soldering, no reflow profile, and no placement machine for a single position — it presses into a panel or board cutout and locks. That makes it a quick-fit option for a jumper or bridge in a harness or board assembly where a soldered header would add process steps.
Cross-Shop: DF59S-1P-FC(21)
The DF59S-1P-FC(21) is the closest functional sibling — same single position, same 3 A and 350 V ratings, same push-mount snap-in style and tin-plated brass contacts. The series suffix differs (DF59S vs DF59SN), but the electrical and mechanical specs align. If the BOM calls for the DF59SN variant and supply is tight, the DF59S-1P-FC(21) is worth evaluating as a drop-in candidate — confirm the housing colour and any subtle dimensional fit from the respective drawings before committing.
