Substitute Part Grouping Explanation

The N548M8CB-TRAY has one identified substitute: N550M8CC-TRAY, also manufactured by Garmin Canada Inc.

Substitution eligibility is determined by the following critical parameters:

• RF Family/Standard: Bluetooth
• Protocol: Bluetooth v4.1
• Frequency: 2.4GHz
• Data Rate: 60kbps
• Power Output: 4dBm
• Sensitivity: -93dBm
• Serial Interfaces: I2C, SPI, UART
• Antenna Type: Integrated, Trace
• Utilized IC: nRF51422
• Memory: 256kB Flash, 16kB RAM
• Voltage Supply: 1.8V ~ 3.6V
• Mounting Type: Surface Mount
• Package/Case: 35-SMD Module
• Moisture Sensitivity Level: 1 (Unlimited)

The N550M8CC-TRAY maintains functional and electrical equivalence across all critical RF, communication, and memory parameters. Both modules utilize the same nRF51422 IC and support identical serial interfaces and antenna configuration.

Parameter Comparison

Engineering Selection Recommendations

The N550M8CC-TRAY is the direct substitute for the obsolete N548M8CB-TRAY. Selection of the N550M8CC-TRAY is supported by the following factors:

• Functional equivalence across all RF, communication protocol, and memory specifications
• Active product status with confirmed inventory availability (2093 Pcs)
• Extended operating temperature range (-40°C ~ 85°C vs. -25°C ~ 75°C), providing broader environmental compatibility
• ROHS3 compliance certification, meeting current regulatory requirements
• Identical packaging, mounting type, and form factor for direct PCB integration
• Same base manufacturer (Garmin Canada Inc.), ensuring design consistency and support continuity

The N550M8CC-TRAY is supplied in Tray packaging, whereas the N548M8CB-TRAY was supplied without specified packaging. Both modules are classified as MSL 1 (Unlimited moisture sensitivity level).

Frequently Asked Questions (FAQ)

Q: Can the N550M8CC-TRAY be used as a direct replacement for the N548M8CB-TRAY?

A: Yes. Both modules are functionally and electrically equivalent across all critical parameters: Bluetooth v4.1 protocol, 2.4GHz frequency, identical RF performance (4dBm output, -93dBm sensitivity), nRF51422 IC, 256kB Flash/16kB RAM memory, and I2C/SPI/UART serial interfaces. The N550M8CC-TRAY has an extended operating temperature range and active product status.

Q: What are the differences between these two parts?

A: The primary differences are product status, operating temperature range, and compliance certification. The N548M8CB-TRAY is obsolete with an operating range of -25°C ~ 75°C. The N550M8CC-TRAY is active, supports -40°C ~ 85°C operation, and carries ROHS3 compliance. Packaging differs: N548M8CB-TRAY has unspecified packaging; N550M8CC-TRAY is supplied in Tray format.

Q: Are there any compatibility concerns when substituting the N550M8CC-TRAY for the N548M8CB-TRAY?

A: No compatibility concerns exist. Both modules use identical mounting type (Surface Mount), package form factor (35-SMD Module), antenna configuration (Integrated Trace), and serial communication interfaces. PCB layout and design integration remain unchanged.

Q: What is the significance of the extended temperature range in the N550M8CC-TRAY?

A: The N550M8CC-TRAY supports operation from -40°C to 85°C, compared to -25°C to 75°C for the N548M8CB-TRAY. This extended range provides compatibility with applications requiring broader environmental operating conditions, including industrial and automotive environments with more extreme temperature exposure.

Q: Is ROHS3 compliance important for this substitution?

A: ROHS3 compliance in the N550M8CC-TRAY indicates adherence to current regulatory requirements for restricted hazardous substances. This is relevant for applications subject to environmental and regulatory compliance mandates. The N548M8CB-TRAY compliance status is not specified in available documentation.
