0.50mm Pitch, 30-Position Mezzanine Receptacle
The 0.020" (0.50mm) pitch and dual-row layout pack 30 circuits into a compact footprint, suited for dense PCB layouts in consumer electronics, portable devices, and industrial control modules where signal routing density is a priority.
Mated Stacking Heights: 4.5mm, 5mm, 6mm
Three mated stacking heights are specified: 4.5mm, 5mm, and 6mm. This gives the board designer flexibility to set the inter-board gap for component clearance or airflow without changing the receptacle — the mating plug height determines the final stack. The 0.122" (3.10mm) height above board of this receptacle is a fixed reference for the bottom board.
30 vs 20 Positions — Same Footprint, Different Density
The 30-position 30R-JMDSS-G-1-TF(S)(LF)(SN) shares the same 0.020" (0.50mm) pitch, dual-row layout, and 0.122" (3.10mm) height above board as the 20-position 20R-JMDSS-G-1-TF. The difference is 10 additional circuits in the same body length — a direct swap on the board footprint if your BOM calls for more I/O. The 40-position variant (40R-JMDSS-G-1-TF) extends the same pattern further.
The JST JMD series, including this 30-position receptacle, carries an Active lifecycle status.
