MAX223CWI Equivalent & Substitute Parts

Part Overview

The MAX223CWI is a 4/5 transceiver full RS232 interface IC manufactured by Analog Devices Inc./Maxim Integrated in 28-SOIC surface mount packaging. This part is classified as obsolete, with 2535 units currently in stock. Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, long-term supply chain planning, and system maintenance. Active alternatives with compatible electrical and mechanical specifications are available from Analog Devices and Renesas Electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX223CWI is determined by the following critical parameters:

• Protocol Compatibility: RS232 full duplex transceiver
• Driver/Receiver Configuration: 4/5 channel architecture
• Package Compatibility: 28-SOIC surface mount form factor
• Supply Voltage Range: 4.5V ~ 5.5V operation
• Electrical Performance: Data rate capability and receiver hysteresis tolerance

Substitute parts are grouped into two categories:

MFR Recommended Substitutes (Analog Devices ADM213 Series): ADM213ARZ, ADM213ARZ-REEL, ADM213EARZ, and ADM213EARZ-REEL meet all mechanical and electrical compatibility requirements. These parts are active products with enhanced operating temperature ranges and RoHS3 compliance.

Parametric Equivalent (Renesas HIN211ECBZ): The HIN211ECBZ from Renesas Electronics matches the receiver hysteresis specification (500 mV) and operating temperature range (0°C ~ 70°C) of the MAX223CWI, providing an alternative from a different manufacturer while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Long-Term Supply: Select ADM213EARZ or ADM213EARZ-REEL. These parts are active products with RoHS3 compliance, extended operating temperature range (-40°C ~ 85°C), and data rate capability (230 kbps) that exceeds the original MAX223CWI specification (250 kbps). The EARZ variant provides the highest data rate among Analog Devices ADM213 options.

For Packaging Preference: ADM213ARZ and ADM213EARZ are supplied in Tube packaging. ADM213ARZ-REEL and ADM213EARZ-REEL are supplied in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats respectively, suitable for automated assembly processes.

For Operating Temperature Matching: HIN211ECBZ from Renesas Electronics maintains the original operating temperature range (0°C ~ 70°C) and receiver hysteresis specification (500 mV) of the MAX223CWI. This part is suitable for applications where the extended temperature range of ADM213 variants is not required. Note the higher moisture sensitivity level (MSL 3) compared to alternatives.

For Regulatory Compliance: All substitute parts are RoHS3 compliant, addressing the non-compliance status of the obsolete MAX223CWI. Analog Devices ADM213 series parts are preferred for new production due to active product status and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can ADM213ARZ directly replace MAX223CWI in existing designs?

A: Yes, mechanically and electrically. The ADM213ARZ maintains the 28-SOIC package, 4/5 RS232 transceiver configuration, and 4.5V ~ 5.5V supply voltage. The receiver hysteresis increases from 500 mV to 650 mV, and data rate capability decreases from 250 kbps to 120 kbps. Designs operating below 120 kbps require no modification. Higher data rate applications should use ADM213EARZ (230 kbps capability).

Q: What is the difference between ADM213ARZ and ADM213EARZ?

A: Both are 4/5 RS232 transceivers in 28-SOIC packaging from Analog Devices. The primary difference is data rate capability: ADM213ARZ supports 120 kbps, while ADM213EARZ supports 230 kbps. Both have 650 mV receiver hysteresis and -40°C ~ 85°C operating temperature range. For applications requiring higher data rates, ADM213EARZ is the appropriate selection.

Q: What packaging options are available for ADM213 substitutes?

A: ADM213ARZ and ADM213EARZ are supplied in Tube packaging for manual assembly or small-volume applications. ADM213ARZ-REEL and ADM213EARZ-REEL are supplied in automated assembly formats (Tape & Reel or Cut Tape & Digi-Reel®). Select based on production volume and assembly method.

Q: Why is HIN211ECBZ listed as a parametric equivalent rather than a recommended substitute?

A: HIN211ECBZ from Renesas Electronics matches the receiver hysteresis (500 mV) and operating temperature range (0°C ~ 70°C) of the MAX223CWI. However, it is from a different manufacturer and has a higher moisture sensitivity level (MSL 3 vs. MSL 1). It serves as a parametric alternative when Analog Devices parts are unavailable, but Analog Devices ADM213 series remains the primary recommendation due to active product status and superior moisture handling.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitutes (ADM213ARZ, ADM213ARZ-REEL, ADM213EARZ, ADM213EARZ-REEL, and HIN211ECBZ) are RoHS3 compliant. The original MAX223CWI is RoHS non-compliant, making substitution necessary for designs requiring regulatory compliance.

Q: What is the inventory status of substitute parts?

A: ADM213ARZ: 3560 units. ADM213ARZ-REEL: 1099 units. ADM213EARZ: 1900 units. ADM213EARZ-REEL: 2000 units. HIN211ECBZ: 3516 units. All are new original stock.
