What sets this variant apart from a typical phone-charger port is the 10000 mating cycle rating.
The package options — Tape & Reel or Cut Tape — suit both pick-and-place lines and small-run hand assembly. Solder retention features and a pick-and-place pad are built in, which means it's designed to stay put during reflow without extra fixturing.
Current and Voltage — What the Ratings Actually Mean
The current rating is listed as 0.5A, 1A, 1.8A — that's not a single number because the allowable current depends on how many contacts are carrying current simultaneously and the ambient temperature. The 30V rated voltage is standard for USB, but the real limit in a micro B is the contact spacing and creepage — stay within USB power delivery specs and you're fine.
Comparing 2174507-2 to 2174507-1
The difference between 2174507-2 and 2174507-1 is typically the packaging or plating variant within the same base product number 2174507. Both are USB micro B receptacles with the same 5-contact, right-angle SMD footprint. The -2 suffix may indicate a specific tape-and-reel quantity or a gold plating thickness grade — the datasheet for the base number will show the exact distinction. For a BOM line, confirm the packaging code matches your assembly line's feeder setup.
