TCAN337D CAN Bus Transceiver Equivalent & Substitute Parts

Part Overview

The TCAN337D is a 1/1 CAN bus transceiver manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This interface IC operates across a 3V to 3.6V supply range and supports 1 Mbps data rates with 120 mV receiver hysteresis. The device is Active status and ROHS3 compliant, making it suitable for automotive and industrial CAN network applications requiring low-voltage operation. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TCAN337D are identified based on strict parameter matching across the following critical criteria:

Mandatory Matching Parameters:

• Protocol: CANbus
• Number of Drivers/Receivers: 1/1
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: -40°C ~ 125°C
• Receiver Hysteresis: 120 mV
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation:

• Data Rate: Substitutes may operate at equal or higher data rates while maintaining full backward compatibility with 1 Mbps operation.

Two substitute parts meet these criteria: TCAN332D and TCAN334GD, both manufactured by Texas Instruments in identical 8-SOIC packaging with matching electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Both TCAN332D and TCAN334GD are direct substitutes for the TCAN337D based on electrical and mechanical parameter equivalence. All three devices maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

TCAN332D provides identical electrical specifications to the TCAN337D, including 1 Mbps data rate operation, making it a direct one-to-one replacement with no functional differences.

TCAN334GD operates at 5 Mbps maximum data rate while maintaining full compatibility with 1 Mbps CAN bus networks. This higher data rate capability does not affect operation in systems designed for 1 Mbps, as the device operates at the lower rate when required by the network.

All three parts share identical supply voltage ranges, thermal operating windows, package geometry, and compliance certifications. Selection between these parts may be based on inventory availability or application-specific data rate requirements.

Frequently Asked Questions (FAQ)

Q: Can TCAN332D replace TCAN337D in existing designs? A: Yes. TCAN332D is electrically and mechanically equivalent to TCAN337D across all specified parameters, including supply voltage, operating temperature, package type, and data rate.

Q: What is the difference between TCAN337D and TCAN334GD? A: Both devices are functionally compatible. TCAN334GD supports 5 Mbps maximum data rate compared to TCAN337D's 1 Mbps rating. In 1 Mbps CAN networks, both operate identically. The higher data rate capability of TCAN334GD does not affect backward compatibility.

Q: Are all three parts pin-compatible? A: Yes. TCAN337D, TCAN332D, and TCAN334GD all use the 8-SOIC package with identical pinout and mechanical dimensions (0.154" width, 3.90mm).

Q: Do these substitutes meet the same compliance requirements? A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited), REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: Can I use TCAN334GD in a 1 Mbps CAN network? A: Yes. TCAN334GD operates at any data rate up to its 5 Mbps maximum, including 1 Mbps networks. No design modifications are required.

Q: Are there any thermal or voltage differences between these parts? A: No. All three devices operate across -40°C to 125°C and require 3V to 3.6V supply voltage with identical receiver hysteresis of 120 mV.
