Power Header for Panel and Bus Distribution
The TE Connectivity 1-353081-3 is a 3-position, single-row, right-angle through-hole header from the Dynamic D-5200 series. It's built for board-to-cable/wire power distribution inside industrial and general-purpose equipment enclosures — think panel wiring, power supply outputs, or bus-bar feeds where you need a disconnect point. The 10.16 mm pitch is unusually wide, which means the board footprint is generous and the creepage distance supports the 630 V rating without forcing an oversized PCB. Each position is rated 30 A, so each contact carries bus-level current — sized for the main DC rail or an AC power feed, not a signal line. The mating interface carries 30 µ" gold plating, a heavy grade that handles repeated mating cycles and resists corrosion in environments where the cabinet isn't climate-controlled.
Mounting and Locking Hardware
This header includes a board lock — a metal barb that presses into the plated through-hole and holds the part in place during wave solder, then resists shear forces from the cable harness after the connector is mated. The 4-wall shroud is keyed with a detent lock, so the mating receptacle clicks in with a positive tactile feel and won't back out under vibration. The right-angle orientation puts the mating face parallel to the board, which suits space-constrained enclosures where the cable exits along the panel rather than straight up.
Environmental and Compliance Ratings
Rated IP20 — finger-safe but not sealed, so this header lives inside an enclosure, not in a washdown zone. The housing is UL94 V-0 rated thermoplastic, polyester with glass fill, which is the standard flame rating for equipment inside a cabinet. Operating temperature spans -55°C to 105°C, covering most industrial cabinet and outdoor telecom enclosure conditions without derating at the high end. Contacts are copper alloy with gold on the mating side and tin on the solder tail — the tin tail wets well in wave solder, and the gold mating surface keeps contact resistance stable over the life of the connection.
Sourcing and Lifecycle
The 1-353081-3 carries an Active lifecycle status from TE — full production, no end-of-life notice, no last-time-buy pressure. No official second-source or cross-reference is on record, so the BOM line matches this exact order code. The base product number is 353081, and the part ships in bulk packaging.
