Is there a KiCad symbol and footprint for the MB4S-TP?
Yes. The symbol is EasyEDA_Cloud:MB4S-E3_80 and the footprint EasyEDA_Cloud:MBS_L4.7-W4.0-P2.50-LS7.0-TL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MB4S-TP?
MBS, with 4 pins. Its footprint is drawn on this page.
Where is the MB4S-TP datasheet?
Micro Commercial Components publishes it: the Datasheet link on this page opens it.
Where can I order the MB4S-TP?
JLCPCB lists it as part C151727, with 6 in stock; the sellers' links on this page open their listings.
What can replace the MB4S-TP?
Parts like it in the library: the MB6S(0.8A) by UMW, the MB4S-E3/80 by Vishay Intertechnology, the MB4S-10 by Shandong Jingdao Microelectronics and the B10SS by Leshan Radio (LRC). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MB4S-TP?
