Is there a KiCad symbol and footprint for the RTT12100JTP?
Yes. The symbol is Device:R and the footprint Resistor_SMD:R_1210_3225Metric, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the RTT12100JTP?
1210, with 2 pins. Its footprint is drawn on this page.
Where is the RTT12100JTP datasheet?
RALEC publishes it: the Datasheet link on this page opens it.
Where can I order the RTT12100JTP?
JLCPCB lists it as part C104957, with 50,008 in stock; the sellers' links on this page open their listings.
What can replace the RTT12100JTP?
Parts like it in the library: the FRC1210J100 TS by FOJAN, the 1210W2F100J by UNI-ROYAL, the 1210W2J0100 by UNI-ROYAL and the FRC1210F10R0TS by FOJAN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
