MAX202ECPE RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX202ECPE is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin DIP package. This interface IC operates at 4.5V to 5.5V supply voltage with a data rate of 120 Kbps and receiver hysteresis of 500 mV. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the MAX202ECPE is determined by strict equivalence across the following critical parameters:

Protocol: RS232
Number of Drivers/Receivers: 2/2
Duplex: Full
Voltage - Supply: 4.5V ~ 5.5V
Mounting Type: Through Hole
Package / Case: 16-DIP (0.300", 7.62mm)
Supplier Device Package: 16-PDIP

Substitute parts are grouped into two categories:

Parametric Equivalents maintain all electrical and mechanical specifications identical to the MAX202ECPE, including receiver hysteresis (500 mV) and data rate (120 Kbps). These parts differ only in product status (active vs. obsolete) and RoHS compliance certification.

Manufacturer Recommended Alternatives are functionally compatible RS232 2/2 transceivers in the same 16-PDIP package but may exhibit variations in receiver hysteresis, data rate, or operating temperature range. These parts are suitable for applications where the primary requirement is RS232 2/2 transceiver functionality within the specified supply voltage and package constraints.

Engineering Selection Recommendations

Direct Parametric Equivalents (MAX202CPE+, MAX202ECPE+, MAX220CPE+, MAX232CPE+, MAX232ECPE+) are the primary substitutes for the MAX202ECPE. These parts maintain identical electrical specifications and are manufactured by Analog Devices Inc./Maxim Integrated with active product status and ROHS3 compliance certification. Selection among these equivalents should be based on inventory availability and packaging preference (tube packaging is standard across all active variants).

Manufacturer Recommended Alternatives (ADM202EANZ, ADM202JNZ, ADM232LJNZ, HIN202ECPZ, LT1081CN#PBF) are suitable for applications where receiver hysteresis, data rate, or operating temperature variations are acceptable. ADM202EANZ and HIN202ECPZ offer enhanced data rate capability (230 Kbps) compared to the original specification. ADM202EANZ additionally supports extended operating temperature range (-40°C ~ 85°C). All recommended alternatives carry ROHS3 compliance and active product status.

Selection should prioritize parts with matching receiver hysteresis (500 mV) and data rate (120 Kbps) specifications when direct parametric equivalence is required. Alternative parts with differing hysteresis or data rate values are suitable only when application requirements permit such variations.

Frequently Asked Questions (FAQ)

Q: Can MAX202CPE+ be used as a direct replacement for MAX202ECPE?

A: Yes. MAX202CPE+ is a parametric equivalent with identical electrical specifications (500 mV receiver hysteresis, 120 Kbps data rate, 4.5V ~ 5.5V supply, 0°C ~ 70°C operating temperature) and the same 16-PDIP package. The primary differences are active product status and ROHS3 compliance certification.

Q: What is the difference between MAX202ECPE+ and MAX232ECPE+?

A: Both are parametric equivalents of the MAX202ECPE with identical electrical and thermal specifications. The difference lies in the base product number designation (MAX202 vs. MAX232 series). Both are suitable substitutes with equivalent performance characteristics.

Q: Can ADM202EANZ replace MAX202ECPE in all applications?

A: ADM202EANZ is functionally compatible as a 2/2 full-duplex RS232 transceiver in the same 16-PDIP package and supply voltage range. However, it differs in receiver hysteresis (650 mV vs. 500 mV) and data rate (230 Kbps vs. 120 Kbps). Substitution is appropriate only when these parameter variations are acceptable for the application.

Q: Why do some substitute parts have different operating temperature ranges?

A: Operating temperature range is a design specification that varies by manufacturer and product line. ADM202EANZ supports -40°C ~ 85°C, while the MAX202ECPE and most alternatives support 0°C ~ 70°C. Selection should match the thermal requirements of the target application.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The original MAX202ECPE is RoHS non-compliant. Compliance certification is an important consideration for applications subject to RoHS regulatory requirements.

Q: What is the significance of receiver hysteresis in RS232 transceiver selection?

A: Receiver hysteresis determines the voltage differential required for the receiver to switch logic states. The MAX202ECPE specifies 500 mV hysteresis. Substitute parts with different hysteresis values (400 mV or 650 mV) may exhibit different noise immunity characteristics. Selection should match application requirements for signal integrity and noise margin.

Q: Can parts from different manufacturers be mixed in the same design?

A: Yes. HIN202ECPZ (Renesas Electronics Corporation) and all Analog Devices Inc. parts are functionally compatible RS232 2/2 transceivers in the 16-PDIP package. Mixing manufacturers is acceptable provided electrical specifications match application requirements. Verify compatibility with your design validation process.

Q: What does the "+" suffix indicate in part numbers like MAX202CPE+?

A: The "+" suffix typically indicates an updated or improved version of the base part number, often with enhanced compliance certifications (such as ROHS3) or packaging improvements. Functionally, MAX202CPE+ is equivalent to MAX202ECPE with the same electrical specifications.
