Overview

The MCR18 is a thyristors (SCR), Module made by WEIDA in a SOT-23 package with 3 pins. -40℃~+110℃ 1 SCR 1.5V 100mW 200uA 5mA 800V 800mA 800mV 8A@50Hz SOT-23 Thyristors (SCR)/Modules ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:BT152_C2900857, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2900848).

Questions

Is there a KiCad symbol and footprint for the MCR18?

Yes. The symbol is EasyEDA_Cloud:BT152_C2900857 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MCR18?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the MCR18 datasheet?

WEIDA publishes it: the Datasheet link on this page opens it.

Where can I order the MCR18?

JLCPCB lists it as part C2900848, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MCR18?

Parts like it in the library: the PCR606 by Jiangsu Changjing Electronics Technology (CJ), the MCR100-6 by HXY MOSFET, the MCR100-8 by HXY MOSFET and the NYC0102BLT1G by Littelfuse. Check their datasheets: a part that fits the footprint may still differ in its ratings.
