MAX239CWG+ Equivalent & Substitute Parts

Part Overview

The MAX239CWG+ is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, configured with 3 drivers and 5 receivers in a 24-SOIC surface mount package. This interface IC operates across a dual voltage supply range (5V and 7.5V to 13.2V) with a maximum data rate of 120 Kbps and receiver hysteresis of 500 mV. The part is currently in active production status with 662 units in stock. Equivalent and substitute parts are identified when they maintain identical electrical specifications, mechanical compatibility, and functional performance within the RS232 transceiver category.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX239CWG+ is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 standard
• Functional Configuration: 3 drivers and 5 receivers in full-duplex mode
• Electrical Performance: 120 Kbps data rate, 500 mV receiver hysteresis
• Supply Voltage Range: 5V and 7.5V to 13.2V dual supply operation
• Operating Temperature Range: 0°C to 70°C
• Package Specification: 24-SOIC surface mount package with 0.295" (7.50mm) width
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The HIN239CBZ from Renesas Electronics Corporation meets all electrical and mechanical parameters required for direct substitution with the MAX239CWG+. Both parts share identical transceiver configuration, voltage supply specifications, data rate capability, and package form factor.

Parameter Comparison

Engineering Selection Recommendations

The MAX239CWG+ is the preferred primary selection due to its active production status and MSL Level 1 rating, which provides unlimited shelf life without moisture sensitivity constraints. The HIN239CBZ is electrically and mechanically equivalent but carries obsolete product status and MSL Level 3 classification, requiring controlled storage conditions (168-hour maximum exposure to 60% relative humidity at 30°C). Selection between these parts should prioritize supply chain continuity and storage capability requirements. Both parts satisfy ROHS3 and REACH compliance requirements for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can HIN239CBZ replace MAX239CWG+ in new designs? A: HIN239CBZ meets all electrical and mechanical specifications for functional equivalence. However, its obsolete status and higher moisture sensitivity level (MSL 3) make it unsuitable for new production designs. MAX239CWG+ is the recommended choice for ongoing applications.

Q: Are there pin-to-pin compatibility differences between MAX239CWG+ and HIN239CBZ? A: Both parts use the 24-SOIC package with identical pinout and electrical characteristics. Pin-to-pin compatibility is confirmed across all driver and receiver channels.

Q: What is the impact of different MSL ratings on component handling? A: MAX239CWG+ with MSL Level 1 has unlimited shelf life and requires no special moisture control. HIN239CBZ with MSL Level 3 must be stored in controlled humidity conditions and has a 168-hour maximum exposure window after packaging opening, requiring accelerated reflow processing or baking before assembly.

Q: Do both parts support the same voltage supply configurations? A: Yes. Both MAX239CWG+ and HIN239CBZ operate identically across the 5V and 7.5V to 13.2V dual supply voltage range with no configuration differences.

Q: Is the 24-SOIC package footprint identical for both parts? A: Yes. Both parts use the 24-SOIC package with 0.295" (7.50mm) width, ensuring identical PCB footprint and assembly compatibility.
