The latch holder is a primary lock — it engages audibly when the header mates with the Micro-Lock PLUS receptacle. No secondary TPA on the header side, but the latch alone keeps the pair mated under moderate vibration. If a terminal backs out, the fix is a crimp replacement on the receptacle side, not a header swap. ## SMT assembly and solder retention Surface-mount termination with pick-and-place cap and solder retention features. Insulation height is 0.352\" (8.95mm) from the board surface — account for this z-height when routing the mated cable bundle under adjacent components. ## Position count variant — 5054482291 at 22 circuits All other specs match: 1.25mm pitch, right-angle SMT, gold plating, latch holder, UL94 V-0. The 24-position part (5054482491) adds two more circuits for a wider signal or power bus — the board footprint grows by 2.5mm in length compared to the 22-position variant.","metaTitle":"Molex 5054482491 Micro-Lock PLUS Header, 24 Pos, 1.25mm","metaDescription":"Molex Micro-Lock PLUS 5054482491 — 24-position, dual-row, 1.25mm pitch, right-angle SMT header.
