The 0791091209 is a 20-position, dual-row receptacle from the Molex Milli-Grid 79109 series.
The gold mating finish (15.0 µinch over nickel) supports repeated mating cycles without oxidation; the tin-plated solder tails keep the board joint cost-effective.
This receptacle mates with Milli-Grid 79109 series pin headers of matching pitch and position count.
Essential for BOM cost estimation and budget planning.
Determines immediate availability for production or prototyping.
Critical for verifying PCB layout compatibility.
Needed to ensure proper connector pair for the application.
Identifies alternative parts if the original is unavailable or requires second sourcing.
Vital for mechanical fit and enclosure design.
