MAX3386ECUP+ Equivalent & Substitute Parts

Part Overview

The MAX3386ECUP+ is a full-duplex RS232 transceiver interface IC manufactured by Analog Devices Inc./Maxim Integrated. This 3/2 transceiver (3 drivers, 2 receivers) operates across 3V to 5.5V supply voltage with a 250 kbps data rate and is housed in a 20-TSSOP surface mount package. The device is currently in active product status with 1900 units in stock.

Substitute parts are necessary when the original MAX3386ECUP+ becomes unavailable, when alternative packaging formats are required, or when extended operating temperature ranges are needed for specific applications. The parts listed maintain electrical and mechanical compatibility within the RS232 transceiver category while offering different manufacturer options, product statuses, and temperature specifications.

Engineering Selection Recommendations

For Direct Replacement (0°C ~ 70°C Operating Range):

Select from parts maintaining identical operating temperature specifications: MAX3223ECUP+, MAX3224CUP+, MAX3224ECUP+ (2/2 configuration), SP3203ECY-L/TR, or TRS3386ECPWR (3/2 configuration). All are in active product status. TRS3386ECPWR offers the highest inventory availability (185,546 units) and is supplied in Cut Tape format with Digi-Reel® packaging.

For Extended Temperature Applications (-40°C ~ 85°C):

Use MAX3386EIPW, MAX3386EIPWR, SP3203EEY-L/TR, or TRS3386EIPWR. These variants support industrial and automotive temperature ranges. Note that MAX3386EIPW and MAX3386EIPWR carry Last Time Buy status, indicating discontinued production. SP3203EEY-L/TR and TRS3386EIPWR maintain active status with 1,629 and 3,920 units in stock respectively.

For Reduced Driver/Receiver Count (2/2 Configuration):

MAX3223ECUP+ and MAX3224ECUP+ series provide 2/2 transceiver functionality within the standard 0°C ~ 70°C range. These are suitable only when application requirements do not exceed 2 drivers and 2 receivers.

Packaging Considerations:

Tube packaging: MAX3386ECUP+, MAX3223ECUP+, MAX3224CUP+, MAX3224ECUP+, MAX3386EIPW

Tape & Reel: SP3203ECY-L/TR, MAX3386EIPWR, SP3203EEY-L/TR

Cut Tape & Digi-Reel®: TRS3386ECPWR, TRS3386EIPWR

Frequently Asked Questions (FAQ)

Q: Can MAX3223ECUP+ or MAX3224ECUP+ replace MAX3386ECUP+ directly?

A: These parts are electrically compatible substitutes but feature 2/2 driver/receiver configuration instead of 3/2. They are suitable only if your application requires no more than 2 drivers and 2 receivers. All other electrical parameters (RS232 protocol, 250 kbps data rate, 3V ~ 5.5V supply, 500 mV hysteresis, 20-TSSOP package) remain identical.

Q: What is the difference between MAX3386ECUP+ and MAX3386EIPWR?

A: Both are 3/2 RS232 transceivers in 20-TSSOP packages. MAX3386EIPWR extends the operating temperature range to -40°C ~ 85°C (versus 0°C ~ 70°C) and is supplied in Tape & Reel format. MAX3386EIPWR carries Last Time Buy status, indicating production discontinuation. For new designs requiring extended temperature operation, SP3203EEY-L/TR or TRS3386EIPWR are recommended as active alternatives.

Q: Are SP3203ECY-L/TR and TRS3386ECPWR pin-compatible with MAX3386ECUP+?

A: Yes. Both maintain the 20-TSSOP package footprint, identical pin count, and full RS232 transceiver functionality with 3/2 driver/receiver configuration. They differ only in manufacturer (MaxLinear and Texas Instruments respectively) and packaging format (Tape & Reel and Cut Tape & Digi-Reel®).

Q: Which substitute offers the best inventory availability?

A: TRS3386ECPWR from Texas Instruments provides the highest stock level at 185,546 units. This part maintains active product status, standard 0°C ~ 70°C operating temperature, and 3/2 transceiver configuration identical to the MAX3386ECUP+.

Q: Can I use parts with -40°C ~ 85°C rating in applications specified for 0°C ~ 70°C?

A: Yes. Extended temperature range parts (MAX3386EIPW, MAX3386EIPWR, SP3203EEY-L/TR, TRS3386EIPWR) are backward compatible with standard temperature specifications. They provide additional thermal margin and are suitable for any application within the 0°C ~ 70°C range.

Q: What does Last Time Buy status mean for MAX3386EIPW and MAX3386EIPWR?

A: Last Time Buy indicates the manufacturer has discontinued production. Existing inventory remains available, but no new manufacturing runs are planned. For long-term supply assurance, select active status alternatives: SP3203EEY-L/TR or TRS3386EIPWR for extended temperature applications.
