Rated at 600 VAC, this header suits general-purpose power distribution inside enclosures where the operating temperature stays between -20°C and 85°C. The 0.163\" (4.14 mm) pitch and 0.163\" (4.14 mm) row spacing define the PCB footprint: a 2×10 grid of 0.175\" (4.45 mm) long solder tails. Confirm this height fits within your enclosure's z-budget before layout. The closest functional second-source is the TE ATX series header 4-1775099-7: same 20 positions, dual rows, locking ramp, through-hole, shrouded 4-wall, and tin-plated contacts. The ATX part uses a 0.165\" (4.20 mm) pitch and square contact shape, versus the 0.163\" (4.14 mm) pitch and circular contact of the Mini-Universal MATE-N-LOK. The ATX part is rated 9 A at 250 VAC; the Mini-Universal MATE-N-LOK is rated 600 VAC with current varying by wire gauge. The ATX header comes in a box package; the Mini-Universal ships in bulk. If your board layout is already set for 4.14 mm pitch, the Mini-Universal MATE-N-LOK header is the direct fit. For a 4.20 mm pitch board, the ATX part is the correct match. Neither crosses cleanly to the other without a footprint change.","metaTitle":"1-794077-0 TE Mini-Universal MATE-N-LOK Header 20 Pos 4.14mm","metaDescription":"1-794077-0 TE Connectivity AMP Connectors Mini-Universal MATE-N-LOK header, 20 positions, 4.14mm pitch, shrouded, board lock, UL94 V-0.
