MAX3380ECUP Equivalent & Substitute Parts

Part Overview

The MAX3380ECUP is a 2/2 transceiver IC implementing full-duplex RS232 communication protocol in a 20-TSSOP surface mount package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The part operates across a 2.4V to 5.5V supply voltage range with a maximum data rate of 460Kbps and is suitable for legacy system maintenance and component replacement scenarios.

Substitute Part Grouping Explanation

Substitution of the MAX3380ECUP is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Driver/Receiver configuration: 2/2 (two drivers, two receivers)
• Duplex mode: Full
• Package type: 20-TSSOP with identical physical dimensions (0.173", 4.40mm Width)
• Mounting technology: Surface Mount
• Electrical performance: Data rate of 460Kbps, receiver hysteresis of 300 mV, supply voltage range 2.4V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Deviations in any of these specifications disqualify a part from substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

The MAX3380ECUP+ is a direct parametric equivalent to the MAX3380ECUP. Both parts share identical electrical specifications, protocol implementation, and physical packaging. The primary distinction is product lifecycle status: the MAX3380ECUP is obsolete while the MAX3380ECUP+ maintains active production status.

For new designs and component procurement, the MAX3380ECUP+ is the appropriate selection. This part offers ROHS3 compliance, addressing regulatory requirements that the original MAX3380ECUP does not satisfy. The MAX3380ECUP+ is available in tube packaging, facilitating standard procurement workflows.

For legacy system maintenance where the original MAX3380ECUP is required, the MAX3380ECUP+ provides functional and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can MAX3380ECUP+ replace MAX3380ECUP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Pin configuration, signal levels, timing characteristics, and package dimensions are equivalent. Direct substitution is possible without circuit modification.

Q: What is the significance of the product status difference?

A: The MAX3380ECUP is classified as obsolete, indicating discontinued production. The MAX3380ECUP+ is active production, ensuring long-term availability and supply chain continuity. For new procurement, the active part is the standard choice.

Q: Does RoHS compliance affect substitution?

A: RoHS compliance is a regulatory and procurement consideration, not a functional one. The MAX3380ECUP+ meets ROHS3 standards while the MAX3380ECUP does not. For applications subject to RoHS requirements, the MAX3380ECUP+ is mandatory. For legacy systems without such constraints, both parts function identically.

Q: Are there packaging differences between these parts?

A: The MAX3380ECUP+ is supplied in tube packaging, while the original part's packaging is unspecified. Both use the 20-TSSOP package format with identical physical dimensions. Tube packaging is standard for component handling and automated assembly processes.

Q: What parameters must remain constant for substitution?

A: RS232 protocol, 2/2 driver/receiver configuration, full-duplex operation, 20-TSSOP package, 460Kbps data rate, 2.4V to 5.5V supply range, 300 mV receiver hysteresis, and 0°C to 70°C operating temperature must all be maintained. Deviation in any parameter disqualifies substitution.
