MAX213ECWI RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX213ECWI is a full-duplex RS232 transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, configured with 4 drivers and 5 receivers in a 28-SOIC surface mount package. This component is classified as obsolete, with 2000 units currently in stock. Due to its obsolete product status, identifying functionally equivalent active alternatives is essential for design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX213ECWI is determined by strict parameter matching across the following critical criteria:

Primary Substitution Parameters:

Protocol: RS232
Number of Drivers/Receivers: 4/5 configuration
Duplex: Full
Receiver Hysteresis: 500 mV
Data Rate: 120 Kbps minimum
Voltage Supply Range: 4.5V ~ 5.5V
Package / Case: 28-SOIC (0.295", 7.50mm Width)
Mounting Type: Surface Mount

Secondary Consideration:

Product Status: Active alternatives are preferred over obsolete parts for new designs
RoHS Compliance: ROHS3 compliant alternatives provide regulatory advantage

Parts are grouped into two categories: parametric equivalents (matching all primary parameters with active status) and direct alternatives (matching electrical specifications with different manufacturer or packaging).

Engineering Selection Recommendations

Preferred Substitutes (Full Parameter Match + Active Status):

MAX211ECWI+, MAX213CWI+, MAX213ECWI+, MAX241CWI+, and MAX241ECWI+ are direct parametric equivalents with active product status and ROHS3 compliance. These parts maintain identical electrical specifications (4/5 driver/receiver configuration, 120 Kbps data rate, 500 mV hysteresis, 4.5V–5.5V supply, 0°C–70°C operating range) and 28-SOIC packaging. Selection among these alternatives should prioritize inventory availability and lead time requirements.

Extended Temperature Alternative:

ADM213ARZ and ADM213ARZ-REEL provide identical electrical performance with extended operating temperature range (-40°C to 85°C) and higher receiver hysteresis (650 mV). These parts are suitable for applications requiring wider temperature operation. Both are ROHS3 compliant and active.

Partial Parameter Match:

MAX214CWI+ operates at 116 Kbps with 3/5 driver/receiver configuration. This part is suitable only for applications where reduced driver count and slightly lower data rate are acceptable.

Obsolete Cross-Reference:

MAX213CDWR (Texas Instruments) matches all electrical parameters but carries obsolete status. This part should not be selected for new designs despite ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can MAX213ECWI be directly replaced with MAX213ECWI+?

A: Yes. MAX213ECWI+ is a direct parametric equivalent with identical electrical specifications, package, and pinout. The primary difference is active product status and ROHS3 compliance versus the obsolete, non-compliant original part.

Q: What is the difference between MAX211ECWI+ and MAX213ECWI+?

A: Both parts share identical electrical parameters (4/5 drivers/receivers, 120 Kbps, 500 mV hysteresis, 4.5V–5.5V supply, 28-SOIC package). The difference lies in the base product series designation (MAX211 versus MAX213). Both are active and ROHS3 compliant.

Q: Is ADM213ARZ a suitable replacement for MAX213ECWI?

A: ADM213ARZ is functionally compatible for applications operating within 0°C–70°C range. It maintains 4/5 driver/receiver configuration, 120 Kbps data rate, and 28-SOIC packaging. However, receiver hysteresis is 650 mV (versus 500 mV) and operating temperature extends to -40°C–85°C. Verify application tolerance for hysteresis variation before selection.

Q: Why is MAX214CWI+ listed as a substitute if it has different driver/receiver count?

A: MAX214CWI+ is included as a partial alternative for applications where 3 drivers and 5 receivers are sufficient. It maintains all other critical parameters (120 Kbps data rate, 500 mV hysteresis, 4.5V–5.5V supply, 28-SOIC package). This part is not a direct replacement but may serve specific design requirements.

Q: What packaging options are available for active substitutes?

A: Active substitutes are available in Tube packaging (MAX211CWI+, MAX211ECWI+, MAX213CWI+, MAX213ECWI+, MAX214CWI+, MAX241CWI+, MAX241ECWI+) and Tape & Reel packaging (ADM213ARZ-REEL). Selection depends on assembly process requirements and order quantity.

Q: Are all active substitutes ROHS3 compliant?

A: Yes. All active substitute parts listed (MAX211 series, MAX213 series, MAX214 series, MAX241 series, and ADM213 series) are ROHS3 compliant. The original MAX213ECWI is RoHS non-compliant.
