Substitute Part Grouping Explanation
Substitution eligibility for the MAX213CDWR is determined by the following critical parameters: RS232 protocol compliance, 4/5 driver/receiver configuration, full-duplex operation, 28-SOIC package footprint, 4.5V to 5.5V supply voltage range, and surface mount mounting type. Parts meeting these core electrical and mechanical specifications are classified as direct equivalents or parametric equivalents. Additional considerations include operating temperature range, data rate capability, receiver hysteresis tolerance, and product status (active vs. obsolete). Parts with enhanced specifications such as extended temperature ranges or higher data rates are classified as upgrades and provide superior performance characteristics while maintaining backward compatibility with the original design.

Engineering Selection Recommendations
For direct replacement of the MAX213CDWR in active production designs, MAX213ECWI+ and MAX213CWI+ maintain identical electrical specifications and 28-SOIC package geometry, differing only in packaging format (Tube vs. Cut Tape). Both parts are active products with ROHS3 compliance and unlimited MSL rating.
MAX211CDWR serves as a parametric equivalent with identical package and operating temperature range, maintaining full compatibility with existing PCB layouts and thermal profiles.
For applications requiring extended operating temperature range (-40°C to 85°C), MAX213EEWI+, ADM213ARZ, and ADM213ARZ-REEL provide active product status with enhanced temperature performance while preserving the 28-SOIC footprint and 4.5V to 5.5V supply specification.
HIN213EIBZ and ADM213EARZ offer upgraded data rate capability (230kbps vs. 120Kbps) with extended temperature ranges, suitable for designs requiring higher communication speeds. ADM213EARZ additionally features 650mV receiver hysteresis compared to the original 500mV specification.
TRS213IDBR is available as an active product alternative from Texas Instruments but requires PCB layout modification due to 28-SSOP package substitution for the original 28-SOIC footprint.
All substitute parts maintain ROHS3 compliance, EAR99 export classification, and identical HTSUS coding, ensuring regulatory and supply chain consistency.
Frequently Asked Questions (FAQ)
Q: Can MAX213ECWI+ directly replace MAX213CDWR without PCB modification?
A: Yes. MAX213ECWI+ maintains identical electrical specifications, 28-SOIC package footprint, and pin configuration. The only difference is packaging format (Tube vs. Cut Tape & Digi-Reel®). No PCB layout changes are required.
Q: What is the difference between MAX213EEWI+ and MAX213ECWI+?
A: Both parts share identical electrical specifications and 28-SOIC packaging. MAX213EEWI+ supports extended operating temperature range (-40°C to 85°C) compared to MAX213ECWI+ (0°C to 70°C). Select MAX213EEWI+ for applications requiring wider temperature performance.
Q: Why is TRS213IDBR listed as a substitute if it uses 28-SSOP packaging?
A: TRS213IDBR is classified as a manufacturer-recommended alternative from Texas Instruments with identical electrical specifications and active product status. However, 28-SSOP packaging differs from the original 28-SOIC footprint, requiring PCB redesign and layout verification before implementation.
Q: Can ADM213EARZ replace MAX213CDWR in existing designs?
A: ADM213EARZ maintains 28-SOIC package compatibility and 4.5V to 5.5V supply specification. However, it features 650mV receiver hysteresis (vs. 500mV) and 230kbps data rate (vs. 120kbps). These enhanced specifications are backward compatible but represent performance upgrades rather than direct equivalents.
Q: What is the advantage of HIN213EIBZ over MAX213CDWR?
A: HIN213EIBZ provides 230kbps data rate capability (vs. 120kbps), extended operating temperature range (-40°C to 85°C vs. 0°C to 70°C), and maintains 28-SOIC package compatibility. It is suitable for designs requiring higher communication speeds and wider temperature operation.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance status, ensuring regulatory consistency with the original MAX213CDWR specification.
Q: What packaging options are available for high-volume procurement?
A: ADM213ARZ-REEL, ADM213EARZ-REEL, and MAX211CDWR are supplied in Tape & Reel (TR) format suitable for automated assembly. ADM213EARZ-REEL is also available in Cut Tape (CT) & Digi-Reel® format. Tube packaging is available for ADM213ARZ, ADM213EARZ, MAX213ECWI+, MAX213EEWI+, and MAX213CWI+.
