Unshrouded means the mating receptacle aligns by the board layout, not a housing key — fine for controlled assembly environments, but in high-vibration applications the lack of a shroud means the mated pair relies entirely on the receptacle's latch for retention. ## Current and Contact: 2 A, Gold-Plated Mating Face The 125 VAC/DC rating and wide temperature range from -40°C to 125°C mean this header can live in automotive under-hood or industrial cabinet environments without derating — as long as the current stays under 2 A per contact. ## Peer Comparison: 2355181-4 vs 1376779-2 The difference: 1376779-2 carries a 3 A current rating and 250 VAC voltage rating, both higher than the 2 A / 125 VAC of 2355181-4. If your BOM needs a bit more headroom without changing the footprint, 1376779-2 is the swap candidate.","metaTitle":"2355181-4 TE Connectivity AMPMODU Header, 4 Pos, 2.00 mm","metaDescription":"2355181-4 TE Connectivity AMPMODU 4-position unshrouded header, 2.00 mm pitch, gold-plated contacts, 2 A, UL94 V-0.
