MAX202EUE+ RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX202EUE+ is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-TSSOP surface mount package. This interface IC operates across a 4.5V to 5.5V supply range with a 120 Kbps data rate and 500 mV receiver hysteresis, designed for serial communication applications requiring dual drivers and receivers.

The MAX202EUE+ carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for systems utilizing this transceiver architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX202EUE+ is determined by strict equivalence across the following critical parameters:

• Protocol & Architecture: RS232 full-duplex transceiver with 2 drivers and 2 receivers
• Electrical Specifications: 4.5V to 5.5V supply voltage, 120 Kbps data rate, 500 mV receiver hysteresis
• Package Compatibility: 16-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm width)
• Operating Range: -40°C to 85°C temperature specification
• Regulatory Compliance: ROHS3 compliance, REACH unaffected status, MSL 1 rating

All substitute parts listed maintain identical electrical performance and mechanical compatibility, enabling direct replacement in existing PCB designs without circuit modification.

Parameter Comparison

Engineering Selection Recommendations

MAX202EEUE+ (Analog Devices Inc./Maxim Integrated) is the primary substitute option. This part maintains Active product status, ensuring ongoing manufacturer support and supply availability. It is packaged in Tube format and carries identical electrical and mechanical specifications to the MAX202EUE+. Current inventory of 2,300 units supports production requirements.

MAX202IPW (Texas Instruments) and TRS202EIPW (Texas Instruments) are parametric equivalents with Obsolete product status. Both parts maintain full electrical and mechanical compatibility with the MAX202EUE+ across all critical parameters. MAX202IPW inventory is 2,000 units; TRS202EIPW inventory is 1,372 units. Selection between these options depends on supply chain availability and long-term sourcing strategy, as both carry obsolete designations.

All three substitute parts satisfy ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity requirements, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can MAX202EEUE+ directly replace MAX202EUE+ without PCB modification?

A: Yes. MAX202EEUE+ is a parametric equivalent with identical electrical specifications (4.5V–5.5V supply, 120 Kbps data rate, 500 mV receiver hysteresis), identical 16-TSSOP package dimensions, and identical pin configuration. Direct substitution on existing PCBs is supported.

Q: What is the difference between MAX202EUE+ and MAX202EEUE+?

A: Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary difference is product status: MAX202EUE+ is Obsolete, while MAX202EEUE+ is Active. Packaging differs (MAX202EUE+ is unspecified; MAX202EEUE+ is Tube format).

Q: Are Texas Instruments parts (MAX202IPW, TRS202EIPW) compatible with MAX202EUE+?

A: Yes. Both Texas Instruments parts maintain identical RS232 transceiver architecture, 2/2 driver/receiver configuration, 16-TSSOP package, and all electrical parameters (supply voltage, data rate, receiver hysteresis, operating temperature). Both carry Obsolete status.

Q: Why should I choose MAX202EEUE+ over the Texas Instruments alternatives?

A: MAX202EEUE+ carries Active product status, indicating ongoing manufacturer support and supply chain continuity. Texas Instruments alternatives (MAX202IPW, TRS202EIPW) are Obsolete, which may impact long-term availability and technical support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MAX202EEUE+, MAX202IPW, and TRS202EIPW all carry ROHS3 compliance certification and REACH unaffected status, matching the regulatory profile of the original MAX202EUE+.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under standard storage conditions. No special moisture control measures are required during storage or handling for any of the listed parts.

Q: Can I mix different substitute parts in the same production run?

A: All listed parts are parametric equivalents with identical electrical and mechanical specifications. Mixing parts from different manufacturers or product statuses is technically feasible but may introduce supply chain complexity. Standardizing on a single part number is recommended for production consistency.
