MAX13050ASA-T CANbus Transceiver Equivalent & Substitute Parts

Part Overview

The MAX13050ASA-T is a full-duplex CANbus transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface mount package. This component interfaces between a microcontroller CAN protocol controller and the physical CAN bus, providing 1/1 driver/receiver configuration with 1 Mbps data rate capability.

The MAX13050ASA-T is classified as obsolete. Equivalent substitute parts are available from the same manufacturer with active product status, offering identical electrical and mechanical specifications while maintaining current production and supply chain availability.

Substitute Part Grouping Explanation

Substitution of the MAX13050ASA-T is determined by strict equivalence across the following critical parameters:

Protocol Compatibility: All substitute parts operate on CANbus protocol
Electrical Configuration: 1/1 driver/receiver, full-duplex operation
Signal Characteristics: 70 mV receiver hysteresis, 1 Mbps maximum data rate
Power Supply: 4.75V to 5.25V operating range
Temperature Range: -40°C to 125°C operational limits
Package Specification: 8-SOIC form factor with identical pinout and mechanical dimensions
Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

All listed substitute parts meet these criteria without exception. Substitution is valid at the functional and mechanical level for direct PCB replacement.

Packaging Format: Choose based on procurement requirements (Tape & Reel, Cut Tape, or bulk)
Supply Chain Lead Time: Active status ensures current availability across all options

All parts carry ROHS3 compliance and MSL Level 1 rating, suitable for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MAX13050ASA-T be directly replaced with MAX13050ASA+T?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: MAX13050ASA-T is supplied in bulk, while MAX13050ASA+T is supplied in Tape & Reel format. PCB placement and soldering requirements are identical.

Q: Are all listed substitute parts pin-compatible with the original MAX13050ASA-T?

A: Yes. All substitute parts use the 8-SOIC package with identical pinout and mechanical dimensions (0.154" width, 3.90mm). Direct PCB replacement is possible without layout modification.

Q: What is the difference between MAX13050, MAX13051, MAX13052, MAX13053, and MAX13054 series?

A: The provided data specifies identical electrical and mechanical parameters across all series variants listed. Substitution is valid based on the parameters provided in this reference.

Q: Does switching from MAX13050ASA-T to an active substitute part require design re-qualification?

A: No design changes are required. All substitute parts meet identical electrical specifications, operating ranges, and compliance certifications. The substitution is a direct functional equivalent.

Q: What is the significance of the "+T" suffix in part numbers like MAX13050ASA+T?

A: The "+T" suffix indicates Tape & Reel packaging format, suitable for automated assembly processes. Parts without this suffix may use alternative packaging formats. Electrical specifications remain identical.
