SP213EEA-L RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The SP213EEA-L is a 4/5 full-duplex RS232 transceiver manufactured by MaxLinear, Inc., housed in a 28-SSOP surface mount package. This component is discontinued at DiGi Electronics but remains available in inventory (1254 pcs). Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Suitable alternatives maintain the same electrical specifications, package form factor, and RS232 protocol compliance.

Substitute Part Grouping Explanation

Substitution of the SP213EEA-L is determined by the following critical parameters:

Protocol Compatibility: RS232 full-duplex transceiver
Driver/Receiver Configuration: 4/5 channel architecture
Package Form Factor: 28-SSOP (0.209", 5.30mm Width)
Voltage Supply Range: 4.5V ~ 5.5V
Data Rate Capability: Minimum 230 kbps
Operating Temperature Range: -40°C ~ 85°C (or compatible subset)
Receiver Hysteresis: 500 mV (or higher)

Substitute parts are grouped into two categories based on data rate performance:

Category A - Full Performance Match (230 kbps)

ADM213EARSZ
ADM213EARSZ-REEL
HIN213EIAZ-T

Category B - Reduced Data Rate (120 kbps)

ADM213ARSZ
ADM213ARSZ-REEL
HIN213ECAZ
HIN213ECAZ-T
MAX213CAI+
MAX213CAI+T
MAX213CDB

All substitute parts maintain the 28-SSOP package, 4.5V ~ 5.5V supply voltage, and full-duplex RS232 protocol. Category A substitutes provide equivalent 230 kbps data rate performance. Category B substitutes operate at 120 kbps and are suitable for applications not requiring the full 230 kbps bandwidth.

Engineering Selection Recommendations

For Full Performance Equivalence (230 kbps, -40°C ~ 85°C)

HIN213EIAZ-T is the primary recommendation. It maintains identical data rate (230 kbps), receiver hysteresis (500 mV), and operating temperature range (-40°C ~ 85°C) as the SP213EEA-L. Renesas Electronics Corporation is an active manufacturer with ROHS3 compliance and highest inventory availability (28357 pcs). This part is available in Cut Tape & Digi-Reel packaging.

ADM213EARSZ and ADM213EARSZ-REEL are secondary options from Analog Devices Inc., matching the 230 kbps data rate and full temperature range. These parts feature slightly higher receiver hysteresis (650 mV) and are available in both Tube and Cut Tape & Digi-Reel packaging formats.

For Reduced Data Rate Applications (120 kbps)

If application requirements permit operation at 120 kbps, multiple active alternatives exist with superior inventory availability. MAX213CAI+T offers the highest inventory (6939 pcs) with standard commercial temperature range (0°C ~ 70°C). HIN213ECAZ-T provides the largest stock (17600 pcs) and maintains the original receiver hysteresis specification (500 mV).

Avoid Obsolete Parts

MAX213CDB is marked obsolete and should not be selected for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I use a 120 kbps substitute in place of the SP213EEA-L?

A: Only if your application operates at or below 120 kbps. The SP213EEA-L supports 230 kbps. Verify your actual data rate requirement before selecting a reduced-speed substitute. All other electrical parameters (voltage, package, driver/receiver count) remain compatible.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging is suitable for manual assembly or small-volume production. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel packaging are designed for automated pick-and-place assembly. Select based on your manufacturing process requirements.

Q: Does receiver hysteresis affect substitutability?

A: Receiver hysteresis of 500 mV or higher is acceptable. The SP213EEA-L specifies 500 mV. Substitutes with 650 mV hysteresis provide improved noise immunity and are functionally compatible. Higher hysteresis does not degrade performance in standard RS232 applications.

Q: Are all substitutes RoHS compliant?

A: Yes. The SP213EEA-L is RoHS Compliant. All active substitute parts carry ROHS3 Compliant certification, meeting current environmental regulations.

Q: Which substitute has the best availability?

A: HIN213EIAZ-T (Renesas) offers the highest inventory at 28357 pcs and provides full performance equivalence (230 kbps, -40°C ~ 85°C). For reduced-speed applications, HIN213ECAZ-T provides 17600 pcs availability.

Q: Can I use MAX213CDB as a substitute?

A: MAX213CDB is marked obsolete and should not be selected for new designs. Use active alternatives such as MAX213CAI+T instead.

Q: What is the operating temperature impact of selecting HIN213ECAZ or MAX213CAI+?

A: These parts operate at 0°C ~ 70°C, which is narrower than the SP213EEA-L range of -40°C ~ 85°C. Select these only if your application operates within the 0°C ~ 70°C window. For full temperature range coverage, use HIN213EIAZ-T, ADM213EARSZ, or ADM213EARSZ-REEL.
