Key Parameters

Substitute Part Grouping Explanation

The MTQ-LAT3-B01.R2A qualifies as a direct substitute based on the following critical parameters:

• RF Protocol Match: Both parts implement 4G LTE CAT-1 (AT&T/T-Mobile) standard
• Frequency Band Compatibility: Identical frequency coverage across 700MHz, 850MHz, 1.7GHz, and 1.9GHz
• Data Rate: Both support 10Mbps data rate
• Serial Interface Compatibility: Both provide I2C, SPI, UART, and USB interfaces
• Antenna Configuration: Both use U.FL chassis mount antenna connector
• Power Supply: Both operate at 5V supply voltage
• Current Consumption: Identical current draw at 58mA for both receiving and transmitting modes
• Operating Temperature Range: Both rated -40°C ~ 85°C
• Mounting Type: Both use chassis mount configuration
• Compliance: Both ROHS3 compliant with MSL 1 rating

The primary distinction is product status: MTQ-LAT3-B01.R2A is active production, while MTQ-LAT3-B01.R2 is obsolete.
