MAX202ECSE RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX202ECSE is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-SOIC surface mount package. This component interfaces between RS232 serial communication lines and TTL/CMOS logic levels, operating at data rates up to 120 Kbps with a supply voltage range of 4.5V to 5.5V.

The MAX202ECSE is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance or redesigns requiring active product status components.

Substitute Part Grouping Explanation

Substitution of the MAX202ECSE is determined by the following critical parameters:

Protocol: RS232
Number of Drivers/Receivers: 2/2
Duplex: Full
Data Rate: 120 Kbps (minimum requirement)
Voltage - Supply: 4.5V ~ 5.5V
Package / Case: 16-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Receiver Hysteresis: 500 mV

Substitute parts are grouped into three categories:

Parametric Equivalents maintain identical electrical and mechanical specifications with active product status and improved RoHS compliance (ROHS3 Compliant).

Direct Substitutes share all critical parameters but may originate from different manufacturers or have minor variations in product status or packaging format.

Upgrade Options extend the operating temperature range to -40°C ~ 85°C while maintaining all other core specifications, suitable for applications requiring extended temperature performance.

Engineering Selection Recommendations

For Direct Replacement with Active Status: MAX202ECSE+ and MAX202CSE+ are parametric equivalents from Analog Devices Inc./Maxim Integrated with active product status and ROHS3 compliance. These parts maintain identical electrical specifications and 16-SOIC packaging, providing the most direct substitution path.

For Alternative Manufacturer Supply: MAX202CDR from Texas Instruments provides equivalent functionality with active supply chain support, though classified as obsolete. ST202ECDR from STMicroelectronics offers active product status with enhanced data rate capability (230 Kbps) while maintaining all core interface parameters.

For Extended Temperature Range Applications: MAX202IDR and MAX202ID extend the operating temperature range to -40°C ~ 85°C, suitable for industrial or automotive environments. MAX202IDR maintains active product status with ROHS3 compliance.

For RoHS Compliance Requirements: All substitute parts except the original MAX202ECSE carry ROHS3 compliance certification, meeting modern environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can MAX202ECSE be directly replaced with MAX202ECSE+? A: Yes. MAX202ECSE+ is a parametric equivalent with identical electrical and mechanical specifications. The primary difference is active product status and ROHS3 compliance instead of RoHS non-compliance.

Q: What is the difference between MAX202CSE+, MAX220CSE+, and MAX232CSE+? A: All three parts share identical electrical specifications (2/2 RS232 transceiver, 120 Kbps, 4.5V ~ 5.5V supply, 16-SOIC package). The base product numbers (MAX202, MAX220, MAX232) indicate different device families within the Maxim Integrated product line, but they are functionally equivalent for this application.

Q: Is ST202ECDR a suitable substitute? A: ST202ECDR meets all core substitution criteria with active product status and ROHS3 compliance. It offers enhanced data rate performance (230 Kbps versus 120 Kbps), making it suitable for applications requiring higher throughput. The 16-SOIC package and electrical interface remain compatible.

Q: Should I use MAX202IDR for standard applications? A: MAX202IDR is suitable for applications requiring extended operating temperature range (-40°C ~ 85°C). For standard commercial temperature range applications (0°C ~ 70°C), MAX202ECSE+ or MAX202CSE+ provide equivalent performance with active status.

Q: Are there packaging format differences between substitutes? A: All listed substitutes use 16-SOIC surface mount packaging. Packaging formats vary between Tube and Cut Tape (CT) & Digi-Reel® options, which affect handling and ordering but not electrical or mechanical compatibility.

Q: What compliance certifications apply to substitute parts? A: All substitute parts carry ROHS3 compliance and REACH Unaffected status. The original MAX202ECSE is RoHS non-compliant. For applications requiring RoHS compliance, select from the active substitute options.
