The MAX202CD is Active and RoHS3 compliant per the manufacturer. That means it's still a valid choice for new designs and production runs, and we can source it through our distribution network.
The MAX202CD and MAX232 are both 2/2 RS-232 transceivers in a 16-SOIC, but the MAX202CD typically runs at 120 kbps while the MAX232 is often rated at 120 kbps as well — the real difference is the charge-pump capacitor configuration. The MAX202 uses four 0.1 µF capacitors; the MAX232 uses four 1 µF capacitors. In practice, if your board is laid out for the MAX232's larger caps, the MAX202CD won't be a drop-in without changing the capacitor values. Pin-compatible otherwise.
Yes, the MAX202CD is pin-compatible with the MAX232, but you must change the external charge-pump capacitors from 1 µF to 0.1 µF. If the board already has 0.1 µF caps, it's a direct swap. If not, you'll need to modify the BOM or the PCB.
Lead time is confirmed at quote time against an RFQ. We don't publish a blanket lead time because it varies with current factory and distributor stock. Submit an RFQ and we'll give you a real lead time.
