MAX203EEPP RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX203EEPP is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin DIP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The MAX203EEPP operates within a 4.75V to 5.25V supply range with a 120 kbps data rate and supports operating temperatures from -40°C to 85°C.

Substitute Part Grouping Explanation

Substitute parts for the MAX203EEPP are classified into two categories based on parametric equivalence and manufacturer recommendation:

Parametric Equivalents (MAX203EEPP+G36, MAX203EPP+G36, MAX233AEPP+G36, MAX233EPP+G36): These parts maintain identical electrical specifications across all critical parameters: 2/2 driver/receiver configuration, full-duplex RS232 protocol, 500 mV receiver hysteresis, 120 kbps data rate, 4.75V to 5.25V supply voltage, -40°C to 85°C operating temperature range, and 20-DIP package. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. non-compliant). These parts are direct functional replacements.

Manufacturer Recommended Alternatives (ADM233LANZ, ADM233LJNZ): These Analog Devices ADM233 series parts maintain the same 2/2 driver/receiver configuration, full-duplex RS232 protocol, 120 kbps data rate, 4.75V to 5.25V supply voltage, 20-DIP package, and mounting type. The key parameter variance is receiver hysteresis (650 mV vs. 500 mV) and operating temperature range. ADM233LANZ supports -40°C to 85°C, while ADM233LJNZ supports 0°C to 70°C. These parts are functionally compatible within their specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): Select MAX203EEPP+G36, MAX203EPP+G36, MAX233AEPP+G36, or MAX233EPP+G36. These parts provide identical electrical specifications to the MAX203EEPP with the advantage of Active product status and ROHS3 compliance. Selection among these four parts may be based on inventory availability and packaging preferences (all supplied in Tube packaging).

For Extended Temperature Range with Hysteresis Tolerance: Select ADM233LANZ when the application requires the full -40°C to 85°C operating temperature range and can accommodate the 650 mV receiver hysteresis specification. This part is manufacturer-recommended and maintains Active status with ROHS3 compliance.

For Commercial Temperature Range Applications: Select ADM233LJNZ when the application operates within 0°C to 70°C and can accommodate the 650 mV receiver hysteresis specification. This part offers the highest inventory availability (7572 units) and is suitable for commercial-grade implementations.

All substitute parts maintain identical 20-DIP through-hole mounting, RS232 protocol compliance, 2/2 driver/receiver configuration, and 120 kbps data rate performance.

Frequently Asked Questions (FAQ)

Q: Can MAX203EEPP be directly replaced with MAX233 series parts? A: Yes. MAX233AEPP+G36 and MAX233EPP+G36 are parametric equivalents with identical electrical specifications, including 500 mV receiver hysteresis and -40°C to 85°C operating temperature. The primary difference is product status and RoHS compliance level.

Q: What is the difference between MAX203 and MAX233 base product numbers? A: Both MAX203 and MAX233 are 2/2 full-duplex RS232 transceivers with identical electrical performance in the specified variants. The base product number difference reflects internal Maxim/Analog Devices product line designation but does not affect functional compatibility for this application.

Q: Can ADM233LJNZ be used in applications requiring -40°C operation? A: No. ADM233LJNZ operates within 0°C to 70°C temperature range. For applications requiring -40°C to 85°C operation, use ADM233LANZ or the MAX203/MAX233 series equivalents.

Q: What is the significance of the receiver hysteresis difference between MAX203EEPP and ADM233 parts? A: Receiver hysteresis affects input threshold switching behavior. MAX203EEPP specifies 500 mV hysteresis, while ADM233 parts specify 650 mV. Both values are within RS232 standard compliance. The higher hysteresis in ADM233 parts provides increased noise immunity but may affect timing-sensitive applications. Verify compatibility with system signal characteristics.

Q: Are all substitute parts available in the same 20-DIP package? A: Yes. All listed substitute parts use the 20-DIP (0.300", 7.62mm) through-hole package with 20-PDIP supplier device package designation, ensuring mechanical and electrical pin compatibility.

Q: What is the packaging difference indicated by "+G36" suffix? A: The "+G36" suffix indicates Tube packaging format. The original MAX203EEPP does not specify packaging type in the provided data. All active substitute parts are supplied in Tube packaging, which is standard for component distribution.

Q: Why is the original MAX203EEPP classified as Obsolete? A: Obsolete status indicates the part is no longer in active production. The listed substitute parts maintain Active status, ensuring continued availability and support for new designs and system maintenance.
