18. Diode Replacement

Question.2

A diode used in a circuit is originally in a small SMD package.
The exact part is unavailable, so it is replaced with a larger diode of the same voltage and current rating, but in a different package.

After replacement, the circuit works, but the PCB layout looks crowded.

What is the main risk with this replacement?

The diode will stop working because bigger packages behave differently
The diode may not fit the PCB properly or may solder poorly
The diode will draw more current because the package is larger
Package size does not matter at all if voltage and current match
