2.50 mm pitch, 5-position right-angle header
Each contact is rated 3 A at 250 V, with the current ceiling limited by the tin plating and the PA66 housing's thermal rise. For a 5-position header, the total power per connector is 15 A distributed across the circuits — adequate for signal and low-power distribution. This is a step up from a simple detent, though not as robust as a secondary TPA lock found in higher-vibration automotive connectors.
Press-fit and solder termination options
The contact post length is 0.134" (3.40 mm), compatible with standard PCB thicknesses.
Peer alternatives for pitch and circuit count
Compared to the CT series peer 1-292164-1 (2.00 mm pitch, 11 positions, detent lock), the 440053-5 offers a wider 2.50 mm pitch with fewer circuits and a friction lock — the wider pitch eases routing for lower-density boards, while the friction lock provides more positive retention than a detent. The.025 series peer 1376366-8 (2.20 mm pitch, 8 positions, 5 A, latch holder) carries a higher current rating and a latch holder for more secure mating. The 440053-5 is a lower-current, lower-circuit option with a simpler friction lock, suited for signal-level connections where 3 A per circuit is sufficient. The automotive peer 953440-3 (2.54 mm pitch, 6 positions, dual row, friction lock) is a dual-row alternative with a similar pitch. The 440053-5's single-row layout simplifies PCB routing and harness assembly for applications requiring only 5 circuits.
