It's a surface-mount board-to-board interconnect designed for parallel stacking — the kind of connector you'll find in compact portable electronics where PCB real estate is tight and the signal count is high. The two-row layout with 80 total positions gives you 40 contacts per row, which is a dense signal interface for applications like LCD panel interconnects, camera modules, or battery management boards where the signal path needs to be short and the connector low-profile. ## Mated Stacking Heights and Board Fit This receptacle is rated for three mated stacking heights: 4.5mm, 5mm, and 6mm. That range covers the typical z-height budget in a mezzanine stack — from a tight 4.5 mm gap up to a more forgiving 6 mm. The actual height your assembly lands on depends on which JMD series header you pair it with; the header's own height above board determines the final stack. If your board stack-up calls for 5 mm, you need to confirm the header part number delivers that exact gap, because the receptacle itself sits at 3.10 mm above the board and the header fills the rest. On a part with 80 pads at 0.50 mm pitch, that retention keeps the connector from shifting during the oven pass, which is the kind of thing that matters when you're placing multiple connectors on a panel. ## How the 80-Position Compares to the 70-Position Sibling The closest same-series alternative is the 70R-JMDSS-G-1-TF, which drops to 70 positions at the same 0.020\" (0.50mm) pitch and 3.10 mm height above board. The 80R-JMDSS-G-1-TF is the same part without the (LF)(SN) suffix; the difference is the lead-free plating and tin finish on the tails, which is a soldering process detail rather than a functional change. Both are active and RoHS compliant.","metaTitle":"JST JMD 80R-JMDSS-G-1-TF(LF)(SN)","metaDescription":"JST JMD series 80-position receptacle, 0.020\" (0.50mm) pitch, SMT, gold contacts, solder retention.
