+## Alternative Parts
+
+Some components can be swapped for more cheaper or more available parts,
+without impacting the functionality of the epdiy controlling board.
+If you find other alternatives that may be useful to others, please submit a pull request!

+| Part name      | Replacement Name   | Default LCSC ID   | Replacement ID  | Comments                                                  |
+| -------------  | ----------------   | ----------------- | --------------- | ---------                                                 |
+| TPS651851RSLR  | TPS65185RSLR       | C139292           | C702311         | Only if your panel size <= 9"                             |
+| XF2M-3315-1A** | FH12-33S-0.5SH(55) | C231420           | C597986         | Omron connector is better quality than Hirose replacement |
+| MBR0540T1G     | B5819W SL          | C8598             | C21353          | Much cheaper diode when ordering from LCSC                |
+
+** IMPORTANT: XF2M-3315-1A replacement C597986 uses a slightly different footprint. It has to be updated in KiCad PCB before sending fabrication files to production.
