MAX220EPE RS232 Transceiver Interface IC - Equivalent & Substitute Parts

Part Overview

The MAX220EPE is a 2/2 full-duplex RS232 transceiver interface IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin DIP package. This component operates as a line driver and receiver for RS232 serial communication protocols, 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 MAX220EPE is classified as obsolete. Equivalent substitute parts are available from multiple manufacturers including Analog Devices, Renesas Electronics, and Texas Instruments, with active product status and improved compliance certifications. Substitution is necessary to ensure long-term component availability, RoHS3 compliance, and continued supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX220EPE are selected based on strict parametric equivalence across the following critical criteria:

Substitution-Determining Parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2
• Duplex Mode: Full
• Receiver Hysteresis: 500 mV
• Data Rate: 120 Kbps
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Through Hole
• Package / Case: 16-DIP (0.300", 7.62mm)
• Supplier Device Package: 16-PDIP

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the original MAX220EPE. Substitutes are grouped by manufacturer and product status, with preference given to active components with current RoHS3 compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS3 Compliant):

For new designs and long-term supply chain continuity, select from active components with RoHS3 compliance:

• MAX232EPE+ (Analog Devices): 9463 units in stock. Highest inventory availability among Analog Devices active substitutes. Maintains identical electrical and mechanical specifications.
• MAX202EPE+ (Analog Devices): 8500 units in stock. Second-highest inventory. Functionally equivalent with active product status.
• HIN232IPZ (Renesas Electronics): 10200 units in stock. Highest overall inventory availability. Alternative manufacturer source for supply chain diversification.

Secondary Substitutes (Obsolete Status, RoHS3 Compliant):

For legacy system maintenance where component obsolescence is acceptable:

• TRS232IN (Texas Instruments): 1900 units in stock. Obsolete status but RoHS3 compliant.
• TRS202EIN (Texas Instruments): 1425 units in stock. Obsolete status but RoHS3 compliant.

Compliance Consideration:

The original MAX220EPE is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements. Selection should prioritize active-status components to ensure manufacturer support and continued availability.

Frequently Asked Questions (FAQ)

Q: Can MAX232EPE+ directly replace MAX220EPE in existing designs?

A: Yes. MAX232EPE+ maintains identical electrical specifications (2/2 RS232 transceiver, 120 Kbps data rate, 4.5V–5.5V supply, -40°C to 85°C operating range) and mechanical compatibility (16-DIP package). Pin-for-pin substitution is supported without circuit modification.

Q: What is the difference between MAX220EPE and MAX220EPE+?

A: MAX220EPE+ is the active-status variant with RoHS3 compliance certification. Both share identical electrical and mechanical specifications. The "+" suffix indicates improved compliance status and current manufacturer support.

Q: Why are there multiple MAX202 and MAX232 variants listed as substitutes?

A: MAX202, MAX220, and MAX232 are different base product numbers within the Analog Devices MAX2xx RS232 transceiver family. All variants maintain the same 2/2 full-duplex RS232 transceiver architecture, 120 Kbps data rate, and 16-DIP package. Substitution is valid across the family based on parametric equivalence.

Q: Is HIN232IPZ from Renesas a suitable alternative to MAX220EPE?

A: Yes. HIN232IPZ is a parametric equivalent from Renesas Electronics with identical electrical specifications and 16-DIP package compatibility. It offers the highest inventory availability (10200 units) and provides manufacturer diversification for supply chain resilience.

Q: Should I avoid obsolete substitutes like TRS232IN?

A: Obsolete components are suitable for legacy system maintenance and repair where component availability is limited. For new designs, active-status substitutes (MAX232EPE+, MAX202EPE+, HIN232IPZ) are recommended to ensure long-term manufacturer support and continued supply chain access.

Q: Are all listed substitutes RoHS3 compliant?

A: All substitute parts listed are RoHS3 compliant. The original MAX220EPE is RoHS non-compliant. Substitution provides compliance upgrade for designs requiring environmental and regulatory adherence.

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

A: Receiver hysteresis of 500 mV is a standard specification for RS232 transceivers that ensures noise immunity and reliable signal detection. All listed substitutes maintain this specification, confirming functional equivalence for RS232 communication applications.
