Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SARA-N410-02B is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Manufacturer: u-blox (same manufacturer ecosystem)
• Mounting Type: Surface Mount with castellation configuration
• Package Case: 96-SMD Module form factor
• Voltage Supply Range: 3.2V ~ 4.2V (identical supply voltage)
• Operating Temperature Range: -40°C ~ 85°C (identical thermal range)
• Moisture Sensitivity Level: 4 (72 Hours) (identical MSL rating)
• Serial Interfaces: Subset compatibility (GPIO, I2C, UART, USB availability)

Functional Compatibility Criteria:

• RF Family/Standard: Cellular transceiver architecture
• Protocol Support: 4G LTE CAT technology (NB-IoT or M1/NB-IoT variants)
• Frequency Band Coverage: Overlap with original 700MHz, 850MHz, 1.7GHz, 1.9GHz bands

The SARA-R410M-02B and SARA-R412M-02B are identified as direct substitutes within the u-blox SARA-R4 series, which represents the active product line evolution from the obsolete SARA-N4 series. Both substitute parts maintain identical physical form factor, electrical supply specifications, and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

SARA-R410M-02B Selection Criteria:

The SARA-R410M-02B is an active product with RoHS compliance and REACH unaffected status. This substitute provides extended frequency band coverage (700MHz through 2.1GHz) compared to the original SARA-N410-02B, supporting both LTE CAT M1 and NB-IoT protocols. The module maintains identical voltage supply, operating temperature, and moisture sensitivity specifications. Serial interface compatibility includes I2C, UART, and USB; however, GPIO is not available and SPI is added. This configuration suits applications requiring multi-band cellular flexibility with active manufacturer support.

SARA-R412M-02B Selection Criteria:

The SARA-R412M-02B is an active product with RoHS compliance and REACH unaffected status. This substitute provides higher data rate capability (375kbps versus 62.5kbps) and increased power output (33dBm versus 23dBm) within a narrower frequency band (850MHz, 900MHz, 1.8GHz, 1.9GHz). Serial interface compatibility includes GPIO, I2C, UART, and USB, matching the original module's interface set. Current consumption is fixed at 360mA for both receive and transmit operations. This configuration suits applications requiring enhanced performance within GSM/LTE band constraints with active manufacturer support.

Both substitutes maintain the 96-SMD Module form factor, enabling direct mechanical compatibility with existing PCB designs. Selection between SARA-R410M-02B and SARA-R412M-02B depends on specific frequency band requirements, data rate demands, and power output specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Why is the SARA-N410-02B classified as obsolete?

A: The SARA-N410-02B has reached end-of-life status within u-blox product portfolio. The manufacturer has transitioned to the SARA-R4 series, which provides enhanced protocol support (LTE CAT M1 in addition to NB-IoT) and extended frequency band coverage while maintaining backward compatibility with existing form factors and electrical specifications.

Q: Are the substitute parts pin-compatible with the SARA-N410-02B?

A: Both SARA-R410M-02B and SARA-R412M-02B utilize the same 96-SMD Module castellation form factor and maintain identical voltage supply specifications (3.2V ~ 4.2V). However, serial interface pin assignments differ: the SARA-R410M-02B includes SPI instead of GPIO, while the SARA-R412M-02B retains GPIO. PCB design review is required to confirm interface compatibility with existing circuit implementations.

Q: What is the difference between SARA-R410M-02B and SARA-R412M-02B?

A: The SARA-R410M-02B supports nine frequency bands (700MHz through 2.1GHz) with unspecified data rate and power output, providing maximum geographic flexibility. The SARA-R412M-02B supports four frequency bands (850MHz, 900MHz, 1.8GHz, 1.9GHz) with specified 375kbps data rate and 33dBm power output, providing enhanced performance within GSM/LTE band constraints. Selection depends on target deployment regions and performance requirements.

Q: Can I use SARA-R410M-02B if my application requires GPIO interface?

A: The SARA-R410M-02B does not include GPIO; it provides I2C, SPI, UART, and USB interfaces. If GPIO functionality is essential, the SARA-R412M-02B is the appropriate substitute, as it includes GPIO, I2C, UART, and USB interfaces matching the original SARA-N410-02B configuration.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes, both SARA-R410M-02B and SARA-R412M-02B are RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity level for these modules?

A: All three modules (SARA-N410-02B, SARA-R410M-02B, and SARA-R412M-02B) have Moisture Sensitivity Level 4 (72 Hours), requiring controlled storage and handling conditions during assembly and deployment.

Q: Do the substitute parts support the same operating temperature range?

A: Yes, all three modules operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility with existing system designs.
