Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTQ-LAT3-B02.R2 is determined by the following critical parameters:

• RF Protocol Compatibility: 4G LTE CAT-1 (AT&T/T-Mobile) standard
• Frequency Band Coverage: 700MHz, 850MHz, 1.7GHz, 1.9GHz
• Antenna Interface: U.FL chassis mount configuration
• Supply Voltage: 5V operation
• Serial Communication Interfaces: Support for UART and USB minimum
• Mounting Configuration: Chassis mount form factor
• Operating Temperature Range: -40°C ~ 85°C
• Environmental Compliance: ROHS3 Compliant

The MTQ-LAT3-B02.R2A qualifies as a direct substitute based on matching all critical RF, electrical, and mechanical parameters. Both modules operate within identical frequency bands, support the same 4G LTE CAT-1 protocol, maintain 5V supply voltage, and share the same U.FL chassis mount antenna interface and operating temperature specifications.
