MAX202ID RS232 Transceiver Equivalent & Substitute Parts
Part Overview
The MAX202ID is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments, housed in a 16-SOIC surface mount 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 MAX202ID is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Active alternatives with identical or superior electrical characteristics are available from multiple manufacturers.

Engineering Selection Recommendations
Tier 1: Direct Substitutes (Recommended for New Designs)
MAX202IDR and MAX202EESE+T are the preferred substitutes. Both are active products with identical electrical specifications to the MAX202ID. MAX202IDR maintains Texas Instruments sourcing continuity, while MAX202EESE+T provides equivalent performance from Analog Devices Inc./Maxim Integrated. Both support the full -40°C to 85°C operating temperature range and are ROHS3 compliant.
Tier 2: Enhanced Performance Alternatives
ADM202EARNZ, ADM202EARNZ-REEL, and ADM202EARNZ-REEL7 from Analog Devices Inc. exceed the electrical specifications of the MAX202ID. These parts operate at 230 Kbps (versus 120 Kbps) and feature 650 mV receiver hysteresis (versus 500 mV). All three variants maintain the -40°C to 85°C temperature range and are ROHS3 compliant. The REEL and REEL7 variants offer superior inventory availability (22,200 and 50,300 units respectively).
Tier 3: Temperature-Restricted Alternatives
ADM202JRNZ variants and HIN202CBNZ operate within a narrower temperature range (0°C to 70°C). These parts are suitable only for applications that do not require the full -40°C to 85°C specification of the MAX202ID. ADM202JRNZ variants feature 400 mV receiver hysteresis. HIN202CBNZ matches the 500 mV hysteresis and 120 Kbps data rate of the original part but is limited to commercial temperature ranges.
Compliance and Certification:
All substitute parts listed are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels range from 1 (unlimited) to 2 (1 year), with MSL-1 parts (MAX202IDR, MAX202EESE+T, ADM202 E-series, and ADM202 J-series) offering superior shelf-life characteristics.
Frequently Asked Questions (FAQ)
Q: Can MAX202IDR be used as a direct replacement for MAX202ID?
A: Yes. MAX202IDR is electrically identical to MAX202ID and shares the same base product number (MAX202). The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube) and active product status. Both operate at 120 Kbps with 500 mV receiver hysteresis across the -40°C to 85°C temperature range.
Q: What is the difference between ADM202EARNZ and ADM202JRNZ?
A: Both are Analog Devices Inc. RS232 transceivers in 16-SOIC packages. ADM202EARNZ operates at -40°C to 85°C with 650 mV hysteresis and 230 Kbps data rate. ADM202JRNZ operates at 0°C to 70°C with 400 mV hysteresis. Selection depends on the required operating temperature range and hysteresis specification for your application.
Q: Is HIN202CBNZ compatible with the MAX202ID?
A: HIN202CBNZ shares the same 16-SOIC package, 2/2 transceiver configuration, 500 mV hysteresis, and 120 Kbps data rate as MAX202ID. However, it operates only within 0°C to 70°C, which is narrower than the MAX202ID specification of -40°C to 85°C. Use HIN202CBNZ only if your application does not require the extended low-temperature operation.
Q: What does the "-REEL" and "-REEL7" designation mean?
A: These designations indicate packaging format. "-REEL" and "-REEL7" variants are supplied on cut tape with Digi-Reel packaging, suitable for automated assembly processes. Standard variants without these suffixes are supplied in tube packaging. Electrical specifications remain identical across packaging variants.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All parts listed in this reference are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
Q: Which substitute offers the best inventory availability?
A: ADM202EARNZ-REEL7 provides the highest inventory level at 50,300 units in stock. ADM202EARNZ-REEL follows with 22,200 units. Both are active products with enhanced electrical specifications (230 Kbps, 650 mV hysteresis) and full temperature range support (-40°C to 85°C).
