JST 50P-JMDSS-G-1-TF — 50-Position JMD Series Plug for Board-to-Board Stacking
The connector is surface-mount with solder retention features — those extra pads on the sides anchor the part to the board during reflow and add shear strength against cable strain or handling after assembly.
At 0.50mm pitch, this is a dense interconnect — the board layout needs matching trace widths and spacing to route all 50 signals out from under the connector. The 4.5mm mated stack height is the only stacking height listed for this variant; if your design needs a different board gap, check the JMD series for other height options. The two-row arrangement keeps the connector width manageable for a 50-position count.
RoHS Status and the LF Variant
This part is marked RoHS non-compliant. For builds requiring RoHS compliance, the alternate order code 50P-JMDSS-G-1-TF(LF)(SN) carries the same pitch, position count, and gold finish but is listed as RoHS-compliant. Both are active in production — no lifecycle concern on either. If your BOM specifies the non-LF version and you need RoHS, the LF variant is a direct swap on the footprint.
