TH8055JDC CANbus Transceiver Equivalent & Substitute Parts

Part Overview

The TH8055JDC is a 1/1 CANbus transceiver manufactured by Melexis Technologies NV, housed in an 8-SOIC surface mount package. This component functions as an interface IC for CAN bus communication systems, operating across a supply voltage range of 5V to 18V with an operating temperature range of -40°C to 125°C.

The TH8055JDC is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TH8055JDC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Protocol: CANbus
• Number of Drivers/Receivers: 1/1
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: Minimum 5V support required

Secondary Compliance Criteria:

• RoHS3 Compliance
• Operating Temperature Range: Minimum -40°C to 125°C support
• Moisture Sensitivity Level: MSL 1 or MSL 3 acceptable

The identified substitute parts maintain the core functional requirements (CANbus protocol, 1/1 transceiver configuration, 8-SOIC package) while offering active product status and enhanced supply availability. Both substitutes support the required voltage and temperature operating ranges with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

TH8056KDC-AAA-008-RE (Melexis Technologies NV)

This substitute maintains identical electrical specifications to the TH8055JDC with the exception of minimum supply voltage (6V versus 5V). The TH8056KDC-AAA-008-RE is an active product with current manufacturing support, ROHS3 compliance, and MSL 1 rating. This part is recommended for applications where the 5V minimum supply voltage of the original part is not a critical requirement. The Melexis manufacturer continuity provides design consistency within the same product family.

NCV7356D1R2G (onsemi)

This substitute provides extended voltage support (5V to 27V) and elevated operating temperature range (-40°C to 150°C), offering broader application flexibility. The NCV7356D1R2G carries AEC-Q100 automotive qualification and active product status. The MSL 3 rating requires controlled moisture handling during storage and assembly. This part is suitable for applications requiring automotive-grade reliability or extended thermal performance margins.

Both substitutes are active products with established supply chains, providing superior availability compared to the obsolete TH8055JDC.

Frequently Asked Questions (FAQ)

Q: Can the TH8056KDC-AAA-008-RE directly replace the TH8055JDC in all applications?

A: The TH8056KDC-AAA-008-RE is functionally equivalent for applications where the minimum supply voltage is 6V or higher. If your design operates at 5V, this substitute is not suitable. Both parts share identical CANbus protocol support, 1/1 driver/receiver configuration, 8-SOIC packaging, and operating temperature range.

Q: What is the key difference between the NCV7356D1R2G and the original TH8055JDC?

A: The NCV7356D1R2G supports a wider supply voltage range (5V to 27V versus 5V to 18V) and higher maximum operating temperature (150°C versus 125°C). The MSL rating differs (MSL 3 versus MSL 1), requiring specific moisture control during component storage and assembly. All other core parameters—protocol, transceiver configuration, and package—are identical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-SOIC package with identical physical dimensions (0.154" width, 3.90mm). Pin compatibility is confirmed for CANbus transceiver applications.

Q: Which substitute should I select for a new design?

A: For new designs, either active substitute is acceptable. Select TH8056KDC-AAA-008-RE if your supply voltage is 6V or higher and you prefer Melexis continuity. Select NCV7356D1R2G if your design requires 5V operation, extended temperature range, or automotive-grade qualification.

Q: What does MSL 3 (168 Hours) mean for the NCV7356D1R2G?

A: MSL 3 indicates the component can absorb moisture for up to 168 hours at specified humidity conditions before assembly. This requires controlled storage in dry-pack conditions and limits the time between package opening and soldering. MSL 1 (unlimited) parts like the TH8055JDC and TH8056KDC-AAA-008-RE have no such time restrictions.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All three parts—TH8055JDC, TH8056KDC-AAA-008-RE, and NCV7356D1R2G—are ROHS3 compliant and REACH unaffected.
