With 0402 and 0201 resistors, it might be cheaper to throw away half of the parts than replacing the feeder. Too bad there is no market for bulk 0402 resistors
Have you considered modifying the feeders of your machine? I imagine this might be easier than adapting a different feeder to your Quad 4000C.

Throwing away the parts is not that big a deal when looking at the cost of the parts, the problem is that they create a mess inside the feeder and the feeder base requiring a cleanup effort. I have considered making a new optical encoder that tricks the feeder into indexing at half the normal distance. It is a software controlled device using relatively ancient tech so tricking the current software seems to be an option.
What other tape pitch do your feeders support?
are they single tape feeders or blocks of tape feeders?
how do they communicate with the controller ( when to advance and how far)?
You mention a sensor. What kind of a sensor is it.. and how does it interact with feed gearing/motor driving the tape?
They are all single feeders, no bank feeders.
They do 4, 8, 12, 16, 24, 32mm indexing.
They control is entirely inside each feeder. There is some optional communication to the machine that ID's the feeder/parts but I don't have that. The feeder has an optical trap that detects the nozzle picking up a part and advances by the programmed amount. If there is an issue with the feeder, the machine does not now about it until it tries to pickup a part and fails to verify vacuum or the part is not detected by the side scanning camera.
There is a super low-tech open optical encoder on the motor - 4 pulses per revolution. I could, in theory, make my own encoder wheels with 8 pulses per rev and it would index 2mm when the control thinks it advanced 4mm.
I was certainly hoping that there was an easy option of buying the smaller parts in tape that indexes at 4mm. Modifying or buying new feeders is slow and/or expensive. I guess I need to pay to move up.
