MAX206EENG Equivalent & Substitute Parts
Part Overview
The MAX206EENG is a 4/3 transceiver full RS232 interface IC manufactured by Analog Devices Inc./Maxim Integrated in a 24-DIP package. This component provides four drivers and three receivers for RS232 serial communication applications. The MAX206EENG is currently classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing system maintenance and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation
Substitution of the MAX206EENG is determined by strict equivalence across the following critical parameters:
- Protocol specification: RS232
- Driver/Receiver configuration: 4/3
- Duplex mode: Full
- Receiver hysteresis: 500 mV
- Data rate capability: 120 Kbps
- Supply voltage range: 4.5V ~ 5.5V
- Operating temperature range: -40°C ~ 85°C
- Physical package: 24-DIP (0.300", 7.62mm)
- Mounting type: Through Hole
The MAX236ENG+ meets all these electrical and mechanical parameters, establishing it as a parametric equivalent to the MAX206EENG. The primary distinction between these parts lies in product status and compliance certifications rather than functional or electrical characteristics.

Engineering Selection Recommendations
The MAX236ENG+ is the direct parametric equivalent for the MAX206EENG across all electrical and mechanical specifications. Selection between these parts should be based on the following factors:
Product Status: The MAX206EENG is obsolete, while the MAX236ENG+ maintains active product status with ongoing manufacturer support and availability.
Compliance Certifications: The MAX236ENG+ is ROHS3 compliant, whereas the MAX206EENG is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the MAX236ENG+ is the appropriate selection.
Availability and Packaging: The MAX236ENG+ is supplied in tube packaging with significantly higher inventory availability (2142 pieces in stock versus 905 pieces for the MAX206EENG), supporting both immediate procurement needs and long-term supply chain continuity.
For new designs or system upgrades, the MAX236ENG+ is the recommended selection. For legacy system maintenance where RoHS compliance is not a constraint, the MAX206EENG remains functionally equivalent until inventory is exhausted.
Frequently Asked Questions (FAQ)
Q: Are the MAX206EENG and MAX236ENG+ pin-compatible?
A: Both parts use the 24-DIP (0.300", 7.62mm) package with identical pinout configurations. Direct socket substitution is supported without PCB modifications.
Q: What is the primary reason to substitute the MAX206EENG?
A: The MAX206EENG is classified as obsolete. The MAX236ENG+ provides equivalent electrical and mechanical functionality with active product status, ensuring long-term availability and manufacturer support.
Q: Does the MAX236ENG+ meet RoHS requirements?
A: The MAX236ENG+ is ROHS3 compliant. The MAX206EENG is RoHS non-compliant. Selection depends on regulatory requirements for your application.
Q: Are there differences in electrical performance between these parts?
A: No. Both parts are specified identically for protocol (RS232), driver/receiver configuration (4/3), duplex mode (full), receiver hysteresis (500 mV), data rate (120 Kbps), supply voltage (4.5V ~ 5.5V), and operating temperature range (-40°C ~ 85°C).
Q: What is the difference in packaging between these parts?
A: The MAX206EENG is supplied in bulk packaging, while the MAX236ENG+ is supplied in tube packaging. Both use the same 24-PDIP physical package format.
Q: Can I use the MAX236ENG+ in existing designs currently using the MAX206EENG?
A: Yes. Electrical specifications, pinout, and package dimensions are identical, supporting direct substitution in existing circuit designs.
