MAX3313EEUB Equivalent & Substitute Parts

Part Overview

The MAX3313EEUB is a 1/1 transceiver IC implementing full RS232 protocol in a 10-uMAX/uSOP surface mount package. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering current product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric matching across all electrical and mechanical specifications. The following criteria establish equivalence:

Protocol: RS232 full duplex transceiver
Driver/Receiver Configuration: 1/1 (one driver, one receiver)
Data Rate: 460 Kbps minimum
Supply Voltage Range: 4.5V ~ 5.5V
Operating Temperature Range: -40°C ~ 85°C
Receiver Hysteresis: 500 mV
Package: 10-TFSOP/10-MSOP with 0.118" (3.00mm) width
Mounting: Surface mount
MSL Rating: 1 (Unlimited)

All substitute parts listed maintain these parameters identically. Differences exist only in product status, RoHS compliance, and packaging format (tube vs. original packaging).

Engineering Selection Recommendations

All four substitute parts are parametrically equivalent to the MAX3313EEUB and are suitable for direct replacement in applications requiring RS232 full duplex transceiver functionality. Selection should prioritize active product status and RoHS3 compliance for new designs and long-term production support.

MAX3313EEUB+ and MAX3313EUB+ maintain the MAX3313 base product number, offering the closest functional continuity. MAX3311EEUB+ and MAX3311EUB+ utilize the MAX3311 base product number but deliver identical electrical performance and mechanical compatibility within the specified parameter set.

All substitute parts carry ROHS3 compliance certification, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level remains 1 (Unlimited) across all alternatives, eliminating bake-out requirements for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can MAX3311EEUB+ replace MAX3313EEUB in existing designs?

A: Yes. Both parts implement identical RS232 1/1 transceiver functionality with matching electrical parameters (460 Kbps data rate, 4.5V–5.5V supply, -40°C to 85°C operating range, 500 mV receiver hysteresis) and identical 10-TFSOP/10-MSOP package dimensions. The base product number difference (MAX3311 vs. MAX3313) does not affect parametric equivalence.

Q: What is the difference between MAX3313EEUB+ and MAX3313EUB+?

A: Both parts share the MAX3313 base product number and are parametrically identical. The difference lies in packaging format: MAX3313EEUB+ is supplied in tube packaging, while MAX3313EUB+ is also supplied in tube packaging. Inventory levels differ (1841 Pcs vs. 967 Pcs), but electrical and mechanical specifications are identical.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts carry ROHS3 compliance certification. The original MAX3313EEUB is RoHS non-compliant, making the substitutes suitable for applications requiring RoHS compliance.

Q: Do substitute parts require different PCB footprints?

A: No. All substitute parts use the 10-TFSOP/10-MSOP package with 0.118" (3.00mm) width, maintaining identical PCB footprint compatibility with the original MAX3313EEUB.

Q: What is the MSL rating for substitute parts?

A: All substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.
