Typical use is in consumer and industrial harnesses where the 4.50mm pitch balances routing density with enough creepage for moderate-voltage DC power distribution. ## Pitch and Layout The 0.177\" (4.50mm) pitch is the critical board-layout dimension for the mating header footprint. It is wider than the 2.54mm standard, giving more room for wire routing and terminal insertion in harness assembly. The 3-row arrangement packs 9 positions into a compact face — verify the mating header's row count matches before specifying. The housing operates from -25°C to 90°C. The free-hanging (in-line) mount lets the housing float on the harness rather than fixing to a panel. The YLP-09V carries 9 positions across 3 rows. The YLP-12V is the 12-position 3-row sibling at the same 4.50mm pitch — same housing style, same latch lock, same contact family.","metaTitle":"JST YLP-09V YL Series Plug Housing, 9 Pos, 4.50mm","metaDescription":"YLP-09V 9-position plug housing from JST's YL series. 4.50mm pitch, 3-row, latch lock, RoHS.
