Frequently Asked Questions
Which listed-pin board-to-board layouts are a good fit for 85791-4020?
85791-4020 fits compact board-to-board layouts that need the listed pin count and datasheet-defined connector spacing. Designers typically use this board-to-board connector where signal routing density and repeatable PCB mating are more important than cable flexibility.
How should procurement compare this listed-pin connector option with nearby Molex connectors?
Compare 85791-4020 against adjacent connector variants by the listed pin count, termination style, plating option, and lifecycle requirements. For builds with inquiry-only stock, confirm lead time and approved alternates before locking a 1-source BOM.
For datasheet-defined SMT assembly, what footprint details matter before approving 85791-4020?
Check the footprint, reel or tray packaging, solder profile, and inspection access against the datasheet. The PCB-mount format and the listed pin count layout should be reviewed with the contract manufacturer before the first production lot.
