The solder retention feature keeps the SMT pads anchored to the board through those repeated insertions, resisting the shear force from cable strain. ## Current Rating Split — 1.8A on the Power Contact, 0.5A on Signals The current rating is split across the contacts: 1.8A on one pin (the VBUS power line) and 0.5A or 1A on the others (the data and ID lines). That 1.8A is enough for a low-power device charging at USB 2.0 levels — think a handheld terminal or sensor node — while the 0.5A on the signal contacts keeps temperature rise in check on the fine-pitch SMT pads. The voltage rating of 30VAC/DC covers the 5V USB bus with generous margin. ## Obsolete — Sourced Through Surplus or Broker Channel JST lists the UB-MC5ABR3-SD204-4S-TB NMP as obsolete. The 5-contact micro AB pinout is standard, so a replacement from another manufacturer with the same footprint and mating interface is a viable alternative, but no direct cross-reference is documented here. Confirm the board footprint and mating plug before substituting. ## Sourcing This Part Because this part is obsolete, it is not held on the shelf.","metaTitle":"JST UB-MC5ABR3-SD204-4S-TB NMP, USB micro AB Receptacle","metaDescription":"JST UB-MC5ABR3-SD204-4S-TB NMP USB micro AB receptacle, 5 contacts, 10,000 mating cycles, SMT right-angle, rated 1.8A/0.5A.
