MAX218CAP Equivalent & Substitute Parts

Part Overview

The MAX218CAP is a 2/2 transceiver IC implementing full-duplex RS232 communication in a 20-SSOP surface mount package. Manufactured by Analog Devices Inc./Maxim Integrated, this component operates across a supply voltage range of 1.8V to 4.25V with a maximum data rate of 120Kbps. The MAX218CAP is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX218CAP is determined by strict equivalence across the following electrical and mechanical parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2 configuration
• Duplex Mode: Full-duplex operation
• Receiver Hysteresis: 100 mV
• Data Rate: 120Kbps maximum
• Supply Voltage Range: 1.8V ~ 4.25V
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 20-SSOP with identical physical dimensions (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

The MAX218CAP+ meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement in applications currently using the obsolete MAX218CAP.

Parameter Comparison

Engineering Selection Recommendations

The MAX218CAP+ is the direct substitute for the obsolete MAX218CAP. Both components share identical electrical specifications and physical packaging, ensuring pin-for-pin compatibility and functional equivalence in RS232 transceiver applications.

The primary distinction between the two parts is product status and regulatory compliance. The MAX218CAP is obsolete and RoHS non-compliant, while the MAX218CAP+ is an active product with ROHS3 compliance. For new designs and systems requiring regulatory adherence to current environmental standards, the MAX218CAP+ is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX218CAP+ directly replace the MAX218CAP in existing designs?

A: Yes. The MAX218CAP+ is a direct parametric equivalent with identical electrical specifications, pin configuration, and 20-SSOP package dimensions. No circuit modifications are required for substitution.

Q: What is the primary reason to transition from MAX218CAP to MAX218CAP+?

A: The MAX218CAP is classified as obsolete. The MAX218CAP+ is an active product from the same manufacturer, ensuring continued availability and supply chain reliability. Additionally, the MAX218CAP+ meets ROHS3 compliance standards, whereas the MAX218CAP does not.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts operate identically across all specified parameters: 2/2 RS232 transceiver configuration, 120Kbps data rate, 1.8V to 4.25V supply voltage, 100 mV receiver hysteresis, and 0°C to 70°C operating temperature range.

Q: Does packaging differ between MAX218CAP and MAX218CAP+?

A: Both parts use the 20-SSOP package with identical physical dimensions (0.209", 5.30mm Width). The MAX218CAP is supplied in standard packaging, while the MAX218CAP+ is supplied in Tube packaging. Both are surface mount components suitable for automated assembly.

Q: Are moisture sensitivity levels the same?

A: Yes. Both the MAX218CAP and MAX218CAP+ have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
