MAX3320BCAP+ Equivalent & Substitute Parts

Part Overview

The MAX3320BCAP+ is a 2/2 full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-SSOP surface mount package. This interface IC operates across a 3V to 5.5V supply range with a 250kbps data rate and 300mV receiver hysteresis, designed for serial communication applications requiring RS232 protocol compliance.

The MAX3320BCAP+ carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3320BCAP+ is determined by strict parametric matching across the following critical criteria:

Electrical Parameters: Protocol (RS232), number of drivers/receivers (2/2), duplex configuration (Full), receiver hysteresis (300mV), data rate (250kbps), and supply voltage range (3V ~ 5.5V).

Mechanical Parameters: Package type (20-SSOP), physical dimensions (0.209" width, 5.30mm), and mounting type (Surface Mount).

Compliance Parameters: RoHS3 compliance, MSL rating (1 - Unlimited), and REACH status (Unaffected).

All identified substitute parts match these parameters completely, ensuring functional and physical interchangeability within the same application context.

Parameter Comparison

Engineering Selection Recommendations

MAX3320ACAP+ (Analog Devices Inc./Maxim Integrated): Active product status provides assured long-term availability and manufacturing support. Identical electrical and mechanical specifications to the MAX3320BCAP+ ensure direct functional replacement. Tube packaging is standard for production quantities.

MAX3320TCAP+ (Analog Devices Inc./Maxim Integrated): Active product status with full parametric equivalence to the original part. Maintains Analog Devices manufacturing lineage and supply chain continuity. Tube packaging supports standard procurement workflows.

MAX3222CDB (Texas Instruments): Cross-manufacturer substitute with complete parametric alignment. Carries Obsolete status; however, inventory availability is documented at 3670 units. Selection of this part requires confirmation of long-term supply viability. Tube packaging is standard.

For new designs or long-term production commitments, MAX3320ACAP+ or MAX3320TCAP+ are preferred due to Active product status. For immediate replacement in existing systems, all three substitutes provide electrical and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can MAX3320ACAP+ or MAX3320TCAP+ be used as direct replacements for MAX3320BCAP+?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and compliance specifications. They operate identically within the same application context and require no circuit modifications.

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

A: Both parts are manufactured by Analog Devices Inc./Maxim Integrated and carry Active product status. They are electrically and mechanically identical. The difference lies in internal temperature grade or binning; both support the 0°C ~ 70°C operating range specified for this application category.

Q: Why is MAX3222CDB listed as a substitute if it is Obsolete?

A: MAX3222CDB meets all parametric requirements for substitution and maintains documented inventory. Obsolete status indicates no new production; however, existing stock remains available. Selection requires verification of supply continuity for your specific application timeline.

Q: Are there any package or pinout differences between these parts?

A: No. All substitute parts use the 20-SSOP package with identical physical dimensions (0.209" width, 5.30mm) and surface mount configuration. Pinout compatibility is guaranteed for direct PCB replacement.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, carry MSL rating 1 (Unlimited), and maintain REACH Unaffected status. Compliance documentation is equivalent across all listed parts.

Q: What inventory levels are available for each substitute?

A: MAX3320ACAP+ has 1243 units in stock. MAX3320TCAP+ has 1115 units in stock. MAX3222CDB has 3670 units in stock. Inventory levels should be verified with your supplier for current availability.
