Six positions, one row — BOM-fit check
With 6 positions loaded (all positions filled), this header matches a 6-circuit MTA-156 receptacle.
Tin plating and current rating — what to expect
Tin on both the mating contact and the solder tail is standard for cost-sensitive, moderate-use interconnects. Tin-plated contacts are rated for fewer mating cycles than gold — typically 25–50 cycles before fretting corrosion becomes a concern in vibration-heavy environments. For a 20 AWG wire, expect around 5–6 A per circuit at a 30 °C temperature rise; the header's tin surface will carry that without issue as long as the mated contact resistance stays below 10 mOhm.
