MAX3320BCAP Equivalent & Substitute Parts

Part Overview

The MAX3320BCAP is a full-duplex RS232 transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, configured with 2 drivers and 2 receivers in a 20-SSOP surface mount package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications while offering improved product status or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3320BCAP is determined by strict equivalence across the following critical parameters: RS232 protocol compliance, 2/2 driver/receiver configuration, full-duplex operation, 250 kbps data rate capability, 3V to 5.5V supply voltage range, 300 mV receiver hysteresis, 0°C to 70°C operating temperature range, 20-SSOP package geometry, surface mount mounting type, and MSL 1 moisture sensitivity rating.

The identified substitute parts—MAX3320ACAP+, MAX3320TCAP+, and MAX3222CDB—satisfy all electrical and mechanical parameters required for direct substitution. These parts are grouped as parametric equivalents based on matching specifications across all critical selection criteria.

Parameter Comparison

Engineering Selection Recommendations

For new designs and procurement, MAX3320ACAP+ and MAX3320TCAP+ are the primary recommended substitutes. Both parts are manufactured by Analog Devices Inc./Maxim Integrated with active product status and ROHS3 compliance certification, providing superior long-term availability and regulatory alignment compared to the obsolete MAX3320BCAP.

MAX3222CDB, manufactured by Texas Instruments, provides an alternative from a different manufacturer while maintaining full parametric equivalence. However, this part carries obsolete product status, limiting its suitability for new procurement despite ROHS3 compliance.

Selection between MAX3320ACAP+ and MAX3320TCAP+ should be based on packaging and inventory requirements, as both parts are electrically and mechanically identical with active status and equivalent compliance certifications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are parametric equivalents with identical electrical specifications (RS232 protocol, 2/2 driver/receiver configuration, 250 kbps data rate, 3V to 5.5V supply voltage, 300 mV receiver hysteresis, 0°C to 70°C operating temperature) and mechanical specifications (20-SSOP package, surface mount mounting). No circuit modifications are required.

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

A: Both parts are electrically and mechanically identical. The primary difference is packaging format: both are supplied in tube packaging. Selection should be based on procurement availability and inventory requirements.

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

A: MAX3222CDB meets all electrical and mechanical substitution criteria and maintains ROHS3 compliance. However, its obsolete status makes it unsuitable for new procurement. It is included for reference in applications where existing inventory exists.

Q: Are there any compliance differences between the main part and substitutes?

A: Yes. MAX3320BCAP is RoHS non-compliant, while MAX3320ACAP+, MAX3320TCAP+, and MAX3222CDB are all ROHS3 compliant. All parts maintain REACH Unaffected status. For applications requiring RoHS compliance, MAX3320ACAP+ or MAX3320TCAP+ are required.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tube) does not affect electrical or mechanical performance. Selection should be based on procurement and handling requirements.
