MAX221EEAE RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX221EEAE is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for serial communication applications requiring single driver and receiver channels. This interface IC operates within the 4.5V to 5.5V supply range and supports data rates up to 250 kbps with a 500 mV receiver hysteresis specification.

The MAX221EEAE is classified as obsolete. Equivalent substitute parts are available in active product status, offering identical electrical and mechanical specifications with improved compliance certifications and current manufacturing support.

Substitute Part Grouping Explanation

Substitute parts for the MAX221EEAE are determined by strict equivalence across all critical electrical and mechanical parameters:

Substitution Criteria:

• Protocol: RS232
• Number of Drivers/Receivers: 1/1 configuration
• Duplex Mode: Full
• Data Rate: 250 kbps
• Supply Voltage Range: 4.5V ~ 5.5V
• Receiver Hysteresis: 500 mV
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 16-SSOP with identical physical dimensions (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Base Product Number: MAX221

All three substitute parts (MAX221EAE+, MAX221ECAE+, MAX221EEAE+) meet these criteria identically. The primary distinction is product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts provide complete electrical and mechanical equivalence to the MAX221EEAE. Selection should be based on the following factors:

Product Status: The MAX221EEAE is obsolete. All substitute parts (MAX221EAE+, MAX221ECAE+, MAX221EEAE+) are in active production status, ensuring long-term availability and manufacturing support.

Compliance Certification: The MAX221EEAE is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Inventory Availability: MAX221ECAE+ offers the highest current inventory (3400 pcs), followed by MAX221EEAE+ (3100 pcs) and MAX221EAE+ (704 pcs). Selection based on supply chain requirements and lead time considerations is appropriate.

Packaging: All substitute parts are supplied in tube packaging, suitable for automated assembly processes and component handling.

Frequently Asked Questions (FAQ)

Q: Are the MAX221EAE+, MAX221ECAE+, and MAX221EEAE+ electrically identical to the MAX221EEAE?

A: Yes. All substitute parts share identical electrical specifications including RS232 protocol, 1/1 driver/receiver configuration, full-duplex operation, 250 kbps data rate, 4.5V to 5.5V supply voltage range, 500 mV receiver hysteresis, and -40°C to 85°C operating temperature range.

Q: Can the MAX221EEAE be directly replaced with any of the substitute parts?

A: Yes. The substitute parts are pin-compatible and functionally equivalent. They use the identical 16-SSOP package with matching physical dimensions (0.209", 5.30mm Width) and surface mount configuration, enabling direct PCB substitution without design modifications.

Q: What is the primary difference between the MAX221EEAE and its substitutes?

A: The primary differences are product status and compliance certification. The MAX221EEAE is obsolete and RoHS non-compliant, while all substitute parts are in active production and ROHS3 compliant. This makes the substitutes suitable for new designs and applications requiring current regulatory compliance.

Q: Which substitute part should be selected for new designs?

A: Any of the three substitute parts (MAX221EAE+, MAX221ECAE+, MAX221EEAE+) is suitable for new designs. Selection should be based on inventory availability, packaging preferences, and supply chain lead times. All parts meet identical electrical and mechanical specifications.

Q: Are there any package or handling differences between the substitute parts?

A: All substitute parts are supplied in tube packaging with MSL 1 (Unlimited) moisture sensitivity level, identical to the original MAX221EEAE specification. No special handling or storage modifications are required.
