MAX202EPE RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX202EPE is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin DIP package. This component interfaces between TTL/CMOS logic levels and RS232 signal levels, supporting data rates up to 120 kbps with a 500 mV receiver hysteresis specification. The MAX202EPE is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing system support. Active alternatives with identical or enhanced electrical characteristics are available from the same manufacturer family.

Engineering Selection Recommendations

Tier 1 - Direct Parametric Equivalents (Recommended for New Designs):

MAX202EEPE+, MAX202EPE+, MAX220EPE+, MAX232EEPE+, and MAX232EPE+ are direct parametric equivalents with identical electrical specifications to the MAX202EPE. All are active products with ROHS3 compliance, making them suitable for new designs and production environments requiring RoHS certification. These parts maintain the 500 mV receiver hysteresis and 120 kbps data rate of the original part while offering superior product lifecycle status and regulatory compliance.

Tier 2 - Enhanced Performance Alternatives:

ADM1181AANZ and ADM202EANZ provide enhanced data rate performance at 230 kbps while maintaining the 4.5V ~ 5.5V supply voltage and -40°C ~ 85°C operating temperature range. These parts feature 650 mV receiver hysteresis, which exceeds the 500 mV specification of the MAX202EPE, providing improved noise immunity. Both are active products with ROHS3 compliance and are manufacturer-recommended alternatives.

Tier 3 - Conditional Alternatives:

ADM232LANZ maintains the 120 kbps data rate with 650 mV receiver hysteresis and full temperature range support. ADM232AANZ offers 200 kbps data rate with 400 mV receiver hysteresis and -40°C ~ 85°C operating temperature. ADM202JNZ operates within a narrower temperature range (0°C ~ 70°C) with 400 mV receiver hysteresis and is suitable only for applications not requiring the full -40°C ~ 85°C specification.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant and carry REACH Unaffected status, meeting modern regulatory requirements. The original MAX202EPE is RoHS non-compliant, making migration to any listed substitute necessary for applications subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can MAX202EPE be directly replaced with MAX202EEPE+ or MAX202EPE+?

A: Yes. MAX202EEPE+ and MAX202EPE+ are parametric equivalents with identical electrical specifications (2/2 drivers/receivers, 120 kbps data rate, 500 mV receiver hysteresis, 4.5V ~ 5.5V supply, -40°C ~ 85°C operating range) and the same 16-DIP package. Both are active products with ROHS3 compliance, making them direct replacements for the obsolete MAX202EPE.

Q: What is the difference between MAX220EPE+ and MAX232EPE+?

A: Both MAX220EPE+ and MAX232EPE+ are parametric equivalents to the MAX202EPE with identical electrical specifications and 16-DIP packaging. The difference lies in the base product series designation (MAX220 versus MAX232), but electrical performance and pin compatibility remain identical for this application.

Q: Can I use ADM1181AANZ or ADM202EANZ as replacements?

A: ADM1181AANZ and ADM202EANZ are manufacturer-recommended alternatives with enhanced data rate performance (230 kbps versus 120 kbps) and higher receiver hysteresis (650 mV versus 500 mV). Both maintain the 2/2 driver/receiver configuration, 16-DIP package, 4.5V ~ 5.5V supply voltage, and -40°C ~ 85°C operating temperature. These parts are suitable replacements when higher data rate capability is beneficial or when improved noise immunity from the higher hysteresis specification is advantageous.

Q: Why is ADM202JNZ listed as a substitute if it has a narrower temperature range?

A: ADM202JNZ is included as a manufacturer-recommended alternative but is conditional on application requirements. It operates only within 0°C ~ 70°C, which is narrower than the MAX202EPE specification of -40°C ~ 85°C. This part is suitable only for applications that do not require the full extended temperature range.

Q: Are all substitute parts available in the same 16-DIP package?

A: Yes. All substitute parts listed are housed in 16-DIP (0.300", 7.62mm) packages with through-hole mounting, ensuring mechanical and pin compatibility with the MAX202EPE. Packaging format variations (such as Tube) do not affect electrical performance or board-level compatibility.

Q: What is the significance of receiver hysteresis differences?

A: Receiver hysteresis determines the voltage difference between the rising and falling threshold levels of the RS232 input comparator. The MAX202EPE specifies 500 mV hysteresis. Substitute parts with equal or greater hysteresis (such as ADM1181AANZ and ADM202EANZ at 650 mV) provide improved noise immunity and are acceptable. Parts with lower hysteresis (such as ADM202JNZ and ADM232AANZ at 400 mV) do not meet the minimum specification and are not recommended for direct replacement unless application requirements explicitly permit reduced hysteresis.

Q: Is RoHS compliance a critical factor for substitution?

A: RoHS compliance is a regulatory requirement for products sold in jurisdictions enforcing RoHS directives. The original MAX202EPE is RoHS non-compliant, while all listed substitutes are ROHS3 compliant. For new designs and production environments, ROHS3 compliance is mandatory. For legacy system repairs or applications not subject to RoHS requirements, compliance is not a functional substitution criterion.
