The 2-row layout with 20 circuits gives a compact 10-per-row arrangement — the footprint fits a tight 0.50 mm grid, so the board layout engineer needs to account for via escape routing under the connector body. Three mated stacking heights — 4.5 mm, 5 mm, and 6 mm — are supported by this receptacle, depending on which plug height variant is chosen. That gives the mechanical designer flexibility to set the board-to-board gap without changing the receptacle BOM line. The 3.10 mm height above board is the z-height of this receptacle alone; the total stack adds the plug height. ## Active Production — No LTB Pressure on This BOM Line JST lists this part as Active. RoHS compliance is confirmed — no additional exemption paperwork needed for EU-market builds. No official cross-reference or second-source exists on record — the JMD series is JST proprietary, so the BOM line locks to this manufacturer. ## Mating and Termination — What Connects Where This receptacle mates with the JMD series plug, specifically the 20P-JMDSS-G-1-TF for a 20-circuit match. The plug carries the outer shroud contacts; the receptacle has the center strip contacts. Termination is SMT only — no through-hole variant in this series. The Tape & Reel packaging suits automated pick-and-place; Cut Tape is also available for prototype or low-volume builds.","metaTitle":"JST JMD 20R-JMDSS-G-1-TF(S)(LF)(SN) 20-Pos 0.50mm Receptacle","metaDescription":"JST JMD 20-position receptacle, 0.50mm pitch, SMT, gold contacts, active.
