MAX232MJE RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX232MJE is a 2/2 RS232 transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-CDIP package. This interface component converts TTL/CMOS logic levels to RS232 voltage levels and vice versa, enabling serial communication between microcontrollers and RS232 devices.

The MAX232MJE is classified as obsolete. Locating equivalent or substitute parts is necessary for design continuity, system maintenance, and production support when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX232MJE is determined by the following critical parameters:

• Protocol Compatibility: RS232 protocol must be maintained
• Driver/Receiver Configuration: 2/2 driver/receiver count must be preserved
• Receiver Hysteresis: 500 mV specification must be matched
• Data Rate: 120 Kbps minimum performance requirement
• Supply Voltage: 5V operation requirement
• Operating Temperature Range: -55°C to 125°C specification must be met or exceeded
• Package Type: 16-CDIP through-hole package for PCB compatibility
• Base Product Number: MAX232 series designation

The MAX232MJE/883B qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX232MJE/883B is a functional equivalent to the MAX232MJE with identical electrical and mechanical specifications. The substitute part is currently in active production status, ensuring availability for ongoing procurement and system support.

Selection between these parts should consider regulatory and compliance requirements:

• MAX232MJE: ROHS3 compliant. Suitable for applications requiring RoHS certification compliance.
• MAX232MJE/883B: RoHS non-compliant. Suitable for legacy systems, military applications, or environments where RoHS compliance is not mandated.

Both parts share identical functional performance, package configuration, and thermal operating range. Electrical characteristics, including receiver hysteresis, data rate, and supply voltage specifications, are equivalent.

Frequently Asked Questions (FAQ)

Q: Can MAX232MJE/883B replace MAX232MJE in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 16-CDIP package pinout is identical, and all electrical specifications match. Substitution is direct without circuit modification.

Q: What is the difference between MAX232MJE and MAX232MJE/883B?

A: The primary differences are product status and RoHS compliance. MAX232MJE is obsolete and ROHS3 compliant. MAX232MJE/883B is active production and RoHS non-compliant. Electrical performance and package type are identical.

Q: Are there package alternatives to 16-CDIP?

A: The specifications provided identify only the 16-CDIP through-hole package. Alternative package types are not included in this equivalency reference.

Q: What does the /883B designation indicate?

A: The /883B suffix indicates a military-grade or extended specification variant within the MAX232 product line. This designation affects compliance certifications but does not alter core electrical functionality.

Q: Is the 120 Kbps data rate sufficient for my application?

A: The 120 Kbps specification is the rated performance of both parts. Application suitability depends on your specific serial communication requirements and baud rate selection.

Q: Can these parts operate outside the -55°C to 125°C temperature range?

A: No. Both parts are specified for operation within -55°C to 125°C. Operation outside this range is not supported and may result in component failure or unpredictable behavior.
