Key Parameters

Substitute Part Grouping Explanation

The MAX216CWN+ qualifies as a direct substitute based on the following matching parameters:

• Identical protocol support: RS232, RS422, AppleTalk
• Identical driver/receiver configuration: 1/1
• Identical duplex mode: Full
• Identical voltage supply range: ±4.75V ~ 5.25V
• Identical operating temperature range: 0°C ~ 70°C
• Identical package and pinout: 18-SOIC (0.295", 7.50mm Width)
• Identical moisture sensitivity level: MSL 1 (Unlimited)

The substitution is valid for all electrical and mechanical interfaces. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX216CWN+ is the appropriate substitute for the obsolete MAX216CWN. Both parts maintain identical electrical and mechanical specifications, ensuring direct pin-for-pin and functional compatibility. The MAX216CWN+ offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and applications requiring regulatory compliance. For existing designs currently using MAX216CWN, migration to MAX216CWN+ requires no circuit modifications or re-qualification of electrical performance.

Frequently Asked Questions (FAQ)

Q: Can MAX216CWN+ be used as a direct replacement for MAX216CWN in existing designs?

A: Yes. The MAX216CWN+ is electrically and mechanically identical to MAX216CWN. No circuit modifications, PCB layout changes, or firmware updates are required. The parts are pin-for-pin compatible with identical protocol support, voltage specifications, and package dimensions.

Q: What is the primary reason to transition from MAX216CWN to MAX216CWN+?

A: The MAX216CWN is classified as obsolete, while MAX216CWN+ maintains active product status. Additionally, MAX216CWN+ is ROHS3 compliant, whereas MAX216CWN is RoHS non-compliant. For new designs and applications subject to regulatory requirements, MAX216CWN+ is the recommended choice.

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

A: No. Both parts use the identical 18-SOIC package with 0.295" width (7.50mm). Pinout, pad layout, and mechanical dimensions are identical, enabling direct PCB compatibility without design modifications.

Q: What protocols does the MAX216CWN+ support?

A: The MAX216CWN+ supports RS232, RS422, and AppleTalk protocols with a 1/1 driver/receiver configuration in full duplex mode.

Q: Are there any supply voltage or temperature range differences?

A: No. Both parts operate with identical supply voltage range (±4.75V ~ 5.25V) and identical operating temperature range (0°C ~ 70°C).
