Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX207CNG+ is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS232 full-duplex transceiver functionality
• Driver/Receiver Configuration: 5 drivers and 3 receivers
• Electrical Specifications: Supply voltage range (4.75V ~ 5.25V), receiver hysteresis (500 mV), data rate (120 Kbps), and operating temperature range (0°C ~ 70°C)
• Physical Form Factor: 24-DIP Through Hole package with 0.300" (7.62mm) pitch
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status

The MAX207ECNG+ meets all these criteria as a parametric equivalent, with the primary distinction being its Active product status and Tube packaging format compared to the Obsolete status of the original part.

Engineering Selection Recommendations

The MAX207ECNG+ is the direct parametric equivalent for MAX207CNG+ replacement. Selection is based on the following engineering criteria:

• Product Status: The MAX207ECNG+ maintains Active status, ensuring continued manufacturer support, availability, and compliance updates. The original MAX207CNG+ is Obsolete, making long-term sourcing impractical.
• Regulatory Compliance: Both parts maintain identical ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory continuity in applications subject to environmental standards.
• Functional Equivalence: All electrical and mechanical parameters are identical, enabling direct substitution without circuit redesign or board layout modification.
• Packaging Consideration: The MAX207ECNG+ is supplied in Tube packaging, which is standard for active production parts. Verify tube quantity requirements align with procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can MAX207ECNG+ be used as a direct replacement for MAX207CNG+ without circuit modifications?

A: Yes. The MAX207ECNG+ is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between MAX207CNG+ and MAX207ECNG+?

A: The primary differences are product status and packaging format. MAX207CNG+ is Obsolete with standard packaging, while MAX207ECNG+ is Active with Tube packaging. All functional and electrical parameters are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 Compliant and REACH Unaffected certifications. Regulatory compliance is maintained across the substitution.

Q: What does the 5/3 driver/receiver configuration mean?

A: The transceiver contains 5 RS232 drivers (transmit channels) and 3 RS232 receivers (receive channels), enabling full-duplex serial communication with asymmetric channel distribution.

Q: Is the 24-DIP package compatible with existing PCB layouts?

A: Yes. Both parts use the identical 24-DIP (0.300", 7.62mm) Through Hole package. Existing PCB footprints and layouts require no modification.

Q: What is the significance of 500 mV receiver hysteresis?

A: Receiver hysteresis of 500 mV defines the voltage differential required between logic state transitions, ensuring noise immunity and stable signal detection in RS232 communication.
