MAX3387ECUG Equivalent & Substitute Parts

Part Overview

The MAX3387ECUG is a full-duplex RS232 transceiver with 3 drivers and 3 receivers, manufactured by Analog Devices Inc./Maxim Integrated. This interface IC operates across a 3V to 5.5V supply range and supports data rates up to 250 kbps. The device is currently classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX3387ECUG is determined by strict equivalence across the following critical parameters:

• Protocol: RS232 full-duplex transceiver
• Driver/Receiver Configuration: 3/3 topology
• Data Rate: 250 kbps minimum
• Supply Voltage Range: 3V ~ 5.5V compatibility
• Package: 24-TSSOP form factor
• Receiver Hysteresis: 500 mV
• Mounting Type: Surface Mount

Substitute parts must maintain identical electrical specifications and physical packaging to ensure direct replacement capability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

MAX3387ECUG+ (Parametric Equivalent): This part maintains identical electrical and thermal specifications to the original MAX3387ECUG while offering active product status and ROHS3 compliance. It is the direct replacement for obsolete stock management and new procurement. The packaging format is Tube.

ISL83387EIVZ and ISL83387EIVZ-T (Cross-Manufacturer Alternatives): Both Renesas parts meet all core electrical parameters and maintain the 24-TSSOP package footprint. These devices extend the operating temperature range to -40°C ~ 85°C, providing enhanced thermal performance for demanding environments. Both achieve ROHS3 compliance. The ISL83387EIVZ is supplied in Tube packaging, while the ISL83387EIVZ-T is available in Cut Tape (CT) & Digi-Reel® format for automated assembly processes.

Selection between these alternatives depends on supply chain availability, packaging requirements for assembly operations, and thermal performance needs. All three substitute parts are electrically and mechanically compatible with the original MAX3387ECUG.

Frequently Asked Questions (FAQ)

Q: Can MAX3387ECUG+ be used as a direct replacement for MAX3387ECUG?

A: Yes. The MAX3387ECUG+ maintains identical electrical specifications, thermal ratings, and 24-TSSOP package dimensions. The primary difference is active product status and improved RoHS compliance. No circuit modifications are required.

Q: What is the difference between ISL83387EIVZ and ISL83387EIVZ-T?

A: Both parts are electrically identical. The difference is packaging format: ISL83387EIVZ is supplied in Tube, while ISL83387EIVZ-T is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements.

Q: Are the Renesas ISL83387 parts compatible with the original MAX3387ECUG circuit?

A: Yes. The ISL83387EIVZ and ISL83387EIVZ-T maintain all critical electrical parameters: RS232 protocol, 3/3 driver/receiver configuration, 250 kbps data rate, 3V ~ 5.5V supply voltage, 500 mV receiver hysteresis, and 24-TSSOP package. No PCB redesign is necessary.

Q: Why do the Renesas parts have a wider operating temperature range?

A: The ISL83387EIVZ and ISL83387EIVZ-T are rated for -40°C ~ 85°C operation, compared to the original 0°C ~ 70°C. This represents enhanced device characterization by Renesas and provides additional thermal margin for applications requiring extended temperature performance.

Q: What does MSL 3 (168 Hours) mean for the Renesas parts?

A: Moisture Sensitivity Level 3 indicates the device requires controlled storage conditions and has a 168-hour floor life after moisture exposure. This is more stringent than the original part's MSL 1 (Unlimited). Proper moisture control during storage and handling is required per IPC standards.

Q: Which substitute should I select for new designs?

A: For new designs, MAX3387ECUG+ or either Renesas ISL83387 variant are acceptable. Selection criteria: use MAX3387ECUG+ for Maxim ecosystem preference and unlimited MSL; use ISL83387EIVZ for Tube packaging in standard assembly; use ISL83387EIVZ-T for automated tape-and-reel assembly processes. All three meet current RoHS3 compliance requirements.
