MAX232IDRG4 Equivalent & Substitute Parts

Part Overview

The MAX232IDRG4 is a 2/2 full-duplex RS232 transceiver manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This interface IC operates across a 4.5V to 5.5V supply range with a 120 Kbps data rate and supports operating temperatures from -40°C to 85°C. The part is currently discontinued at DiGi Electronics, making equivalent and substitute parts essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX232IDRG4 is determined by strict parameter matching across the following critical specifications:

Core Substitution Criteria:

Protocol: RS232
Number of Drivers/Receivers: 2/2
Duplex: Full
Voltage - Supply: 4.5V ~ 5.5V
Package / Case: 16-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parametric Equivalents match all core criteria and maintain identical electrical performance specifications including receiver hysteresis (500 mV), data rate (120 Kbps), and operating temperature range (-40°C ~ 85°C).

Direct Manufacturer Equivalents are functionally identical parts with different packaging designations from the same manufacturer lineage.

Manufacturer Recommended Substitutes meet core substitution criteria but may have minor variations in receiver hysteresis, data rate specification, or operating temperature range. These parts are actively supported by their respective manufacturers and provide functional compatibility within the RS232 interface category.

Engineering Selection Recommendations

Preferred Active Substitutes (Parametric Equivalents):

MAX202IDR, MAX232IDR, and TRS202EIDR are parametric equivalents manufactured by Texas Instruments with active product status. These parts maintain identical electrical specifications to the MAX232IDRG4 across all critical parameters including receiver hysteresis, data rate, and operating temperature range. All three are ROHS3 compliant with MSL 1 rating and are available in active inventory.

Direct Manufacturer Equivalent:

MAX232ESE+ is a direct equivalent from Analog Devices Inc./Maxim Integrated with identical electrical specifications and active product status. This part is supplied in Tube packaging and maintains full compatibility with the MAX232IDRG4 across all functional parameters.

Manufacturer Recommended Alternatives:

ADM202JRNZ, ADM202JRNZ-REEL, and ADM202JRNZ-REEL7 from Analog Devices Inc. are actively supported alternatives. These parts operate within the same supply voltage range and package footprint but feature a reduced operating temperature range (0°C ~ 70°C) and lower receiver hysteresis (400 mV). Selection of these parts is appropriate for applications operating within the 0°C to 70°C temperature window.

ADM232AARNZ-REEL from Analog Devices Inc. offers enhanced data rate capability (200 Kbps) while maintaining the full -40°C to 85°C operating temperature range and 400 mV receiver hysteresis. This part is suitable for applications requiring higher data throughput within the extended temperature specification.

Frequently Asked Questions (FAQ)

Q: Can MAX202IDR be used as a direct replacement for MAX232IDRG4?

A: Yes. MAX202IDR is a parametric equivalent with identical electrical specifications including 500 mV receiver hysteresis, 120 Kbps data rate, and -40°C to 85°C operating temperature range. Both parts are housed in 16-SOIC packages and are ROHS3 compliant. The primary difference is product status: MAX202IDR is currently active while MAX232IDRG4 is discontinued.

Q: What is the difference between the ADM202 and ADM232 series?

A: The ADM202 series operates within a 0°C to 70°C temperature range with 400 mV receiver hysteresis. The ADM232 series extends the operating temperature to -40°C to 85°C and offers higher data rate capability (200 Kbps for ADM232AARNZ-REEL). Selection depends on application temperature requirements and data rate specifications.

Q: Are all substitute parts available in the same packaging?

A: All listed substitutes are housed in 16-SOIC surface mount packages with identical footprints. Packaging designations (Tube, Cut Tape & Digi-Reel) refer to supply format rather than component packaging. Verify specific packaging availability with your supplier.

Q: Do all substitutes meet the same compliance standards?

A: All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for all parts. ECCN and HTSUS classifications are identical across all substitutes.

Q: Which substitute offers the best compatibility for extended temperature applications?

A: MAX202IDR, MAX232IDR, TRS202EIDR, and ADM232AARNZ-REEL all maintain the -40°C to 85°C operating temperature range. For applications requiring this full temperature specification, these parts provide direct compatibility with the MAX232IDRG4.

Q: Can ADM202JRNZ be used in applications requiring -40°C operation?

A: No. ADM202JRNZ operates within a 0°C to 70°C temperature range and is not suitable for applications requiring -40°C minimum operating temperature. Use MAX202IDR, MAX232IDR, TRS202EIDR, or ADM232AARNZ-REEL for extended low-temperature operation.
