MAX3313EUB RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX3313EUB 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 460 Kbps with a 500 mV receiver hysteresis specification.

The MAX3313EUB is classified as obsolete. Equivalent substitute parts are available from the same manufacturer with active product status, offering identical electrical and mechanical specifications while providing improved availability and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX3313EUB is determined by strict parametric equivalence across the following criteria:

RS232 protocol implementation with full-duplex 1/1 driver/receiver configuration
Identical data rate specification of 460 Kbps
Matching supply voltage range of 4.5V ~ 5.5V
Identical operating temperature range of -40°C ~ 85°C
Receiver hysteresis of 500 mV
Surface mount packaging in 10-TFSOP/10-MSOP form factor
10-uMAX/uSOP supplier device package designation
MSL rating of 1 (Unlimited)

All substitute parts listed maintain these electrical and mechanical parameters without deviation. Substitutes differ only in product status (active versus obsolete) and RoHS compliance certification level.

Engineering Selection Recommendations

The MAX3313EUB is classified as obsolete and carries RoHS non-compliant status. All four substitute parts—MAX3311EEUB+, MAX3311EUB+, MAX3313EEUB+, and MAX3313EUB+—maintain identical electrical and mechanical specifications while offering active product status and ROHS3 compliance certification.

Selection among active substitutes should be based on inventory availability and packaging requirements. MAX3311EEUB+ offers the highest current inventory at 2400 pieces. All substitutes are supplied in tube packaging and maintain the 10-uMAX/uSOP device package designation. REACH status is unaffected across all parts, and ECCN classification remains EAR99 for all variants.

Frequently Asked Questions (FAQ)

Q: Can MAX3311EEUB+ directly replace MAX3313EUB in existing designs?

A: Yes. Both parts maintain identical RS232 protocol implementation, 1/1 driver/receiver configuration, 460 Kbps data rate, 4.5V to 5.5V supply voltage, -40°C to 85°C operating temperature range, 500 mV receiver hysteresis, and 10-TFSOP/10-MSOP surface mount packaging. Electrical and mechanical compatibility is complete.

Q: What is the difference between MAX3311 and MAX3313 base part numbers?

A: The provided data specifies identical electrical and mechanical parameters for both base part families. Substitution is permitted across both families based on the parametric equivalence criteria listed.

Q: Are there packaging differences between substitute options?

A: All substitute parts are supplied in tube packaging within the 10-TFSOP and 10-MSOP form factors. The 10-uMAX/uSOP supplier device package designation is consistent across all variants.

Q: What compliance certifications apply to the substitute parts?

A: All active substitute parts carry ROHS3 compliance certification. REACH status is unaffected for all parts. ECCN classification is EAR99 for all variants. The original MAX3313EUB is RoHS non-compliant.

Q: Which substitute part offers the best availability?

A: MAX3311EEUB+ currently maintains the highest inventory level at 2400 pieces in stock.
