# Should I take precautions when using different CAN transceivers on the same bus?

What are the precautions I should be aware of when using different transceivers on a CAN bus?

What I can think of:

• They neeed to operate at the same voltage (on CAN_H and CAN_L)
• They need to have some common baudrates (at least one)

Is there anything else?

For example I would like to use both these transceivers on the same CAN bus:

• As it happens I use exactly those 2 on the same buses all the time. Microchip has a newer part MCP2561 which is pin compatible though, just better. – Lundin Apr 2 '19 at 15:14
• I'm doing CAN for a hobby project and the MCP2551 is easier to find and a little bit cheaper. You are right to point that Microchip recommends to use the MCP2561 instead. – Victor Lamoine Apr 3 '19 at 7:57
