MAX3320LCAP Equivalent & Substitute Parts

Part Overview

The MAX3320LCAP is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-SSOP surface mount package. This component operates across a 3V to 5.5V supply range with a 250kbps data rate and 300mV receiver hysteresis, designed for serial communication interface applications.

The MAX3320LCAP is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for legacy systems or new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3320LCAP is determined by strict equivalence across the following parameters:

• Protocol: RS232
• Number of Drivers/Receivers: 2/2
• Duplex Mode: Full
• Receiver Hysteresis: 300 mV
• Data Rate: 250kbps
• Supply Voltage Range: 3V ~ 5.5V
• Operating Temperature Range: 0°C ~ 70°C
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Substitutes are grouped by manufacturer and product status to facilitate selection based on availability and compliance requirements.

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS3 Compliant):

MAX3320ACAP+ and MAX3320TCAP+ are the preferred substitutes. Both are manufactured by Analog Devices Inc./Maxim Integrated with active product status and ROHS3 compliance. These parts maintain identical electrical specifications and 20-SSOP packaging. Selection between these two depends on packaging preference: MAX3320ACAP+ is supplied in Tube packaging, while MAX3320TCAP+ is supplied in Tube packaging. Both offer superior compliance posture compared to the obsolete MAX3320LCAP.

Secondary Substitutes (Obsolete Status, RoHS3 Compliant):

MAX3222CDB and MAX3222CDBR are cross-manufacturer alternatives from Texas Instruments. Both maintain full electrical equivalence and RoHS3 compliance but carry obsolete product status. MAX3222CDB is supplied in Tube packaging; MAX3222CDBR is supplied in Tape & Reel (TR) packaging. These options are suitable when primary substitutes are unavailable.

Compliance Consideration:

The original MAX3320LCAP is RoHS non-compliant. All listed substitutes are ROHS3 compliant, supporting modern regulatory requirements and supply chain standards.

Frequently Asked Questions (FAQ)

Q: Can MAX3320ACAP+ or MAX3320TCAP+ be used as direct replacements for MAX3320LCAP?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (RS232 protocol, 2/2 drivers/receivers, 250kbps data rate, 3V–5.5V supply, 0°C–70°C operating range) and identical 20-SSOP packaging. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between MAX3320ACAP+ and MAX3320TCAP+?

A: Both parts are electrically and mechanically identical. The difference is in packaging format: MAX3320ACAP+ is supplied in Tube packaging, while MAX3320TCAP+ is supplied in Tube packaging. Selection depends on assembly line requirements and inventory management preferences.

Q: Are the Texas Instruments MAX3222 series parts compatible with MAX3320LCAP?

A: Yes. MAX3222CDB and MAX3222CDBR meet all electrical and mechanical substitution criteria. They are cross-manufacturer equivalents with identical protocol, driver/receiver configuration, data rate, supply voltage, operating temperature, and package specifications. The primary consideration is that both are obsolete, making them suitable only when Analog Devices alternatives are unavailable.

Q: What packaging options are available for substitutes?

A: Substitutes are available in Tube and Tape & Reel (TR) packaging formats. MAX3320ACAP+ and MAX3320TCAP+ are supplied in Tube; MAX3222CDBR is supplied in Tape & Reel (TR); MAX3222CDB is supplied in Tube. Packaging selection should align with assembly process requirements and volume needs.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a material composition and manufacturing standard that does not alter electrical performance. All listed substitutes maintain identical electrical specifications regardless of RoHS status.

Q: Are there inventory considerations for these substitutes?

A: Inventory levels vary by part number and supplier. MAX3320ACAP+ (1243 pcs), MAX3320TCAP+ (1115 pcs), MAX3222CDB (3670 pcs), and MAX3222CDBR (5120 pcs) are available in stock. Availability should be confirmed with your component supplier for current stock status.
