Substitute Part Grouping Explanation

Substitution of the MAX3218CAP is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Driver/Receiver configuration: 2/2
• Duplex mode: Full
• Receiver hysteresis: 700 mV
• Data rate capability: 120 Kbps
• Supply voltage range: 1.8V ~ 4.25V
• Operating temperature range: 0°C ~ 70°C
• Package type: 20-SSOP with identical physical dimensions
• Mounting technology: Surface Mount

The MAX3218CAP+ maintains identical electrical and mechanical specifications across all parameters listed above, establishing it as a direct parametric equivalent suitable for substitution.

Parameter Comparison

Engineering Selection Recommendations

The MAX3218CAP+ is the appropriate selection for new designs and procurement activities. This part maintains complete electrical and mechanical compatibility with the MAX3218CAP while offering the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies current environmental and regulatory requirements
• Identical parametric specifications enable direct substitution without circuit modification
• Packaging and mounting characteristics remain unchanged, supporting existing PCB layouts

The MAX3218CAP remains suitable for legacy system maintenance and repair applications where existing inventory is available and regulatory compliance requirements do not mandate RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can MAX3218CAP+ be used as a direct replacement for MAX3218CAP in existing designs?

A: Yes. The MAX3218CAP+ maintains identical electrical specifications across all functional parameters including protocol, driver/receiver configuration, data rate, supply voltage range, and operating temperature. Physical package dimensions and mounting type are identical, supporting direct PCB compatibility.

Q: What is the primary difference between MAX3218CAP and MAX3218CAP+?

A: The primary differences are product status and regulatory compliance. MAX3218CAP is obsolete with RoHS non-compliant status. MAX3218CAP+ is active with ROHS3 compliance, ensuring continued availability and meeting current environmental regulations.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 20-SSOP package with identical physical dimensions (0.209" width, 5.30mm). Pinout and mounting characteristics are identical.

Q: What supply voltage range do these transceivers support?

A: Both parts operate across a supply voltage range of 1.8V to 4.25V, supporting single-supply applications in this range.

Q: What is the maximum data rate for RS232 communication with these transceivers?

A: Both parts support a data rate of 120 Kbps for RS232 protocol communication.

Q: Are moisture sensitivity considerations different between the two parts?

A: No. Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
