SMD resistor series & which can I sub for ERJ-xE?

[popflier]

Thanks Rich. Yes, I need 0603.
I asked about this series of resistors in particular because in Fredrik’s answer to my other (similar) question I understood it to mean (essentially) that using a different series of resistor mostly depends on how the resistor is used in the circuit since each series has different properties.

I wasn’t sure if the Elements circuit would allow me to change to a different series since he had looked at the other circuit? I think if I understood how the resistors were used in the circuit I could answer my own question. I’m just not there yet.

If my understanding is not correct please tell me. BTW…I didn’t see that checkbox option for comparisons so that’s great to have instead of me going back and forth on two different tabs. Thanks.

This was his answer to that question.

What’s the circuit? Resistors are resistors, and their main property is the nominal resistance. All other things depend on where the resistor is used:

• Tolerance (how important is the exact resistance value in the given circuit?).
• Footprint (if you have an existing PCB).
• Power rating (if exposed to enough voltage, and the resistance is low enough, it needs to be able to handle the current going through it)
• Temperature coefficient (if used in temperature-sensitive precision circuits, where the resistance value must change in the same way as other component values elsewhere in the circuit)
• Voltage rating (if using in high-voltage circuits)
• Packaging (if you’re using a machine to populate your PCBs)

For most cases, the first and maybe the second additional property is all that matters.
