Pitch, Pinout, and Footprint Decisions
The 77311-846-20LF: The 0.100" pitch sets a standard board footprint that routes easily on two-layer PCBs. All 20 positions are loaded, so the pinout matches a 20-contact receptacle one-to-one.
Material and Environmental Ratings
The operating temperature range spans -65°C to 125°C, covering most industrial and automotive interior environments. Contact material is phosphor bronze with a tin post finish (78.7 µinch) for reliable solderability.
