SIPEX
Sipex RS-232 transceiver ICs in stock at YILUDA TECH. Five Sipex lines are held as 100% original, new and unused material, all in surface-mount packages.
Parts on the shelf
- SP3232E family — SP3232EEY-L/TR and SP3232ECY-L/TR in SSOP-16 and TSSOP-16, SP3232ECN in SOIC-16 and SP3232EBCN-L/TR in SOP-16.
- SP232E — SP232EEN-L/TR in SOP-16, the lower-drive variant for short cable runs.
All are two-driver, two-receiver devices intended to sit between a 3.3 V or 5 V logic rail and a true RS-232 line.
What to watch when replacing one
RS-232 transceivers are pin-compatible across manufacturers far more often than they are electrically identical. Charge-pump capacitor count, data rate and the exact supply range differ between suffixes, and a part rated for 3.3 V will not always tolerate a 5 V rail. The SP3232E parts in this collection are the ones most often used as a direct replacement for MAX232-style sockets, but the schematic should be checked first.
Ordering notes
- The trailing -L/TR denotes lead-free tape and reel; state if you need tube packing instead.
- Package width differs between SSOP and SOIC — confirm the footprint on your board.
- Worldwide shipping from Shenzhen by DHL, FedEx or UPS.
Part numbers on hand
SP3232EEY-L/TR, SP3232ECY-L/TR, SP3232ECN, SP3232EBCN-L/TR and SP232EEN-L/TR are listed as available.
Are these drop-in for a MAX232?
Pinout is compatible in most cases, but check the supply voltage and capacitor configuration against your schematic before ordering.

Cross-reference notes
An SP232 drives a shorter cable than an SP3232, and swapping one for the other changes how much capacitance the line will tolerate. Charge-pump capacitor values also differ between families; a circuit built for 0.1 µF parts may not start reliably with the values intended for a different device. When replacing a MAX232-style socket, check both the supply voltage and the capacitor configuration against the schematic before ordering.
