Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX3387EEUG are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Protocol: RS232
• Number of Drivers/Receivers: 3/3
• Duplex Mode: Full
• Data Rate: 250kbps
• Supply Voltage Range: 3V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 24-TSSOP
• Receiver Hysteresis: 500 mV

All identified substitute parts match these parameters exactly. Substitutes are categorized by their relationship to the main part and their current product status.

Engineering Selection Recommendations

MAX3387EEUG+ (Parametric Equivalent): This part is the direct parametric equivalent from the same manufacturer with identical electrical specifications. It maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements while preserving all functional characteristics. The MSL rating of 1 provides superior moisture handling compared to the original obsolete part.

ISL83387EIVZ-T (Manufacturer Recommended): This Renesas Electronics part is designated as the manufacturer-recommended substitute. It provides full parametric equivalence with ROHS3 compliance and active product status. The MSL rating of 3 (168 Hours) is suitable for standard manufacturing environments. Cut Tape and Digi-Reel packaging options support high-volume procurement workflows.

ISL83387EIVZ (Parametric Equivalent): This Renesas Electronics alternative offers identical electrical performance to the main part with active product status and ROHS3 compliance. Tube packaging is available, and the MSL rating of 3 (168 Hours) is appropriate for controlled storage conditions.

Selection among these substitutes should be based on procurement requirements, packaging preferences, and supply chain availability rather than functional differences, as all parts meet the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can MAX3387EEUG+ be used as a direct replacement for MAX3387EEUG? A: Yes. MAX3387EEUG+ is a parametric equivalent with identical electrical specifications, including protocol, driver/receiver configuration, data rate, supply voltage, operating temperature range, and package type. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What are the key differences between Analog Devices and Renesas substitute options? A: Both manufacturers provide parts meeting all critical electrical parameters. The Analog Devices MAX3387EEUG+ maintains the same manufacturer lineage as the original part. Renesas ISL83387EIVZ and ISL83387EIVZ-T options differ in packaging format (Tube vs. Cut Tape/Digi-Reel) and MSL rating (3 vs. 1), but deliver equivalent functional performance.

Q: Does MSL rating affect part selection? A: MSL rating indicates moisture sensitivity during storage and handling. MAX3387EEUG+ has MSL 1 (Unlimited), while Renesas parts have MSL 3 (168 Hours). Selection depends on your manufacturing environment and storage protocols. MSL 3 parts require controlled humidity storage but are suitable for standard manufacturing conditions.

Q: Are all substitute parts available in the same 24-TSSOP package? A: Yes. All substitute parts use the 24-TSSOP (0.173", 4.40mm Width) package, ensuring mechanical compatibility with existing PCB designs and assembly processes.

Q: What is the significance of RoHS compliance for these parts? A: The original MAX3387EEUG is RoHS non-compliant. All substitute parts (MAX3387EEUG+, ISL83387EIVZ-T, ISL83387EIVZ) are ROHS3 compliant, meeting current environmental and regulatory standards for electronic components in most markets.

Q: Can packaging format affect my procurement decision? A: Packaging format (Tube vs. Cut Tape/Digi-Reel) impacts handling, storage, and automated assembly compatibility. MAX3387EEUG+ and ISL83387EIVZ are supplied in Tube format. ISL83387EIVZ-T offers Cut Tape and Digi-Reel options, which may be preferred for high-volume automated pick-and-place operations.
