MAX202ESE RS232 Transceiver Equivalent & Substitute Parts
Part Overview
The MAX202ESE is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-SOIC surface mount package. This component operates as a line driver and receiver for RS232 serial communication interfaces, supporting data rates up to 120 kbps with a supply voltage range of 4.5V to 5.5V and operating temperature range of -40°C to 85°C.
The MAX202ESE is classified as obsolete. Equivalent and substitute parts are available from the same manufacturer in active product status, as well as from alternative manufacturers including Renesas Electronics Corporation and STMicroelectronics. These alternatives maintain the core electrical and mechanical specifications required for direct substitution in RS232 transceiver applications.

Engineering Selection Recommendations
Direct Replacement (Identical Specifications):
For applications requiring exact electrical and mechanical compatibility with no design modifications, select from the parametric equivalents: MAX202EESE+, MAX202ESE+, MAX220ESE+, MAX232EESE+, or MAX232ESE+. All are manufactured by Analog Devices Inc./Maxim Integrated and maintain the 16-SOIC (0.154", 3.90mm Width) package footprint. These parts are active products with RoHS3 compliance, eliminating the obsolescence and regulatory compliance issues of the original MAX202ESE.
Alternative Manufacturer Equivalents:
HIN202IBNZ-T (Renesas Electronics Corporation) and ST202BDR (STMicroelectronics) provide direct functional equivalence with identical package dimensions and electrical specifications. ST202BDR offers enhanced data rate capability (400 kbps versus 120 kbps), providing additional performance margin without requiring circuit modifications.
Enhanced Performance Alternatives:
ADM202EARNZ maintains the original 16-SOIC (0.154", 3.90mm Width) package while providing higher receiver hysteresis (650 mV) and data rate (230 kbps). This part is suitable for applications where improved noise immunity and higher communication speeds are beneficial.
ADM1181AARWZ and ADM1181AARWZ-REEL offer the same enhanced electrical performance but in a larger 16-SOIC (0.295", 7.50mm Width) package. These parts require PCB layout verification to confirm package footprint compatibility before selection.
Compliance Considerations:
All substitute parts listed are RoHS3 compliant and REACH unaffected, addressing regulatory requirements that may not be met by the obsolete MAX202ESE. Moisture sensitivity levels range from MSL 1 (Unlimited) to MSL 3 (168 Hours), with no impact on functional substitution for standard storage and handling conditions.
Frequently Asked Questions (FAQ)
Q: Can MAX202ESE be directly replaced with MAX202EESE+ or MAX202ESE+?
A: Yes. MAX202EESE+ and MAX202ESE+ are parametric equivalents with identical electrical specifications (2/2 drivers/receivers, 120 kbps data rate, 500 mV receiver hysteresis, 4.5V to 5.5V supply) and package dimensions (16-SOIC, 0.154" width). Both are active products with RoHS3 compliance. No circuit modifications are required.
Q: What is the difference between MAX232EESE+ and MAX202ESE?
A: Both parts share identical electrical specifications and package dimensions. The primary difference is product status: MAX202ESE is obsolete, while MAX232EESE+ is active. The base product numbers (MAX202 versus MAX232) indicate different internal configurations, but both function as 2/2 full-duplex RS232 transceivers suitable for the same applications.
Q: Can I use ST202BDR as a substitute for MAX202ESE?
A: Yes. ST202BDR meets all core electrical and mechanical requirements: 2/2 drivers/receivers, RS232 protocol, 500 mV receiver hysteresis, 4.5V to 5.5V supply, -40°C to 85°C operating range, and 16-SOIC package. ST202BDR offers enhanced data rate capability (400 kbps versus 120 kbps), providing additional performance margin. No circuit modifications are required.
Q: Are ADM1181AARWZ and ADM202EARNZ pin-compatible with MAX202ESE?
A: Both parts are functionally equivalent RS232 transceivers with identical electrical specifications and supply requirements. ADM202EARNZ maintains the original 16-SOIC (0.154", 3.90mm Width) package and is directly pin-compatible. ADM1181AARWZ uses a larger 16-SOIC (0.295", 7.50mm Width) package and requires PCB layout verification before selection. Both offer enhanced performance (230 kbps data rate, 650 mV receiver hysteresis).
Q: What is the significance of the "+" suffix on part numbers like MAX202ESE+?
A: The "+" suffix indicates tube packaging. Parts without the "+" suffix (such as the original MAX202ESE) may use different packaging formats. For applications requiring specific packaging (tube, tape & reel, or cut tape), verify the packaging specification matches your procurement and assembly requirements.
Q: Can HIN202IBNZ-T replace MAX202ESE in a new design?
A: Yes. HIN202IBNZ-T is a direct equivalent manufactured by Renesas Electronics Corporation with identical electrical specifications and package dimensions. It is an active product with RoHS3 compliance. No design modifications are required.
Q: What is the difference in receiver hysteresis between MAX202ESE and ADM202EARNZ?
A: MAX202ESE has 500 mV receiver hysteresis, while ADM202EARNZ has 650 mV. Higher hysteresis provides improved noise immunity in noisy environments. Both values are within standard RS232 specifications and do not affect functional compatibility. Selection depends on application noise requirements.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed are RoHS3 compliant. The original MAX202ESE is RoHS non-compliant. If regulatory compliance is required, select from the active substitute parts provided.
