Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX218CWP is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232 full-duplex communication
• Channel configuration: 2 drivers and 2 receivers
• Electrical performance: 100 mV receiver hysteresis, 120Kbps data rate capability
• Supply voltage range: 1.8V to 4.25V operation
• Physical form factor: 20-SOIC package with 0.295" (7.50mm) width
• Thermal operating range: 0°C to 70°C

The MAX218CWP+ meets all these parameters while offering improved product status and regulatory compliance, making it a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAX218CWP+ is the direct parametric equivalent for the obsolete MAX218CWP. Both parts share identical electrical specifications, pin configuration, and package form factor. The MAX218CWP+ offers two significant advantages: active product status ensuring continued manufacturer support and availability, and ROHS3 compliance meeting current regulatory requirements for new designs and procurement.

For applications requiring the MAX218CWP, the MAX218CWP+ provides a drop-in replacement with no design modifications necessary. The transition from RoHS non-compliant to ROHS3 compliant status reflects current environmental and regulatory standards applicable to electronic components.

Frequently Asked Questions (FAQ)

Q: Can the MAX218CWP+ directly replace the MAX218CWP in existing designs?

A: Yes. The MAX218CWP+ is a parametric equivalent with identical electrical performance, pin configuration, and 20-SOIC package dimensions. No circuit modifications are required.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active status indicates the MAX218CWP+ remains in current production with manufacturer support, technical documentation, and supply chain availability. Obsolete status for the MAX218CWP indicates end-of-life status with limited future availability.

Q: How does ROHS3 compliance affect component selection?

A: ROHS3 compliance ensures the component meets current environmental regulations for hazardous substance restrictions. This is relevant for new designs, procurement policies, and regulatory compliance requirements in target markets.

Q: Are the electrical specifications identical between both parts?

A: Yes. Both parts operate at 1.8V to 4.25V supply voltage, support 120Kbps data rate, provide 100 mV receiver hysteresis, and implement full-duplex RS232 communication with 2 drivers and 2 receivers.

Q: What packaging options are available?

A: The MAX218CWP+ is supplied in Tube packaging. Both parts use the 20-SOIC surface mount package with 0.295" (7.50mm) width.
