MTQ-LAT3-B01.R2-SP Equivalent & Substitute Parts

Part Overview

The MTQ-LAT3-B01.R2-SP is a Cellular 4G LTE CAT-1 transceiver module manufactured by Multi-Tech Systems Inc. as part of the MultiTech Dragonfly™ series. This RF transceiver module supports AT&T and T-Mobile networks across 700MHz, 850MHz, 1.7GHz, and 1.9GHz frequency bands with U.FL chassis mount antenna connectivity and 10Mbps data rate capability. The module interfaces via I2C, SPI, UART, and USB serial protocols and operates from a 5V supply with 58mA current draw in both receiving and transmitting modes.

The MTQ-LAT3-B01.R2-SP has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing system deployments where this module is integrated.

Substitute Part Grouping Explanation

Substitution eligibility for the MTQ-LAT3-B01.R2-SP is determined by strict alignment across the following critical parameters:

Protocol Compatibility: The substitute must support 4G LTE CAT-1 (AT&T/T-Mobile) protocol to maintain network compatibility.

Frequency Band Coverage: The substitute must support all four frequency bands: 700MHz, 850MHz, 1.7GHz, and 1.9GHz.

Serial Interface Support: The substitute must provide I2C, SPI, UART, and USB interfaces for system integration.

Antenna Connector: The substitute must use U.FL chassis mount antenna configuration.

Electrical Specifications: The substitute must operate at 5V supply voltage with equivalent current consumption in receiving and transmitting modes.

Operating Temperature Range: The substitute must maintain -40°C to 85°C operating temperature specification.

Mechanical Form Factor: The substitute must be a module-type package suitable for chassis mount installation.

Regulatory Compliance: The substitute must maintain ROHS3 compliance status.

The MTQ-LAT3-B01.R2A-SP meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MTQ-LAT3-B01.R2A-SP is the direct substitute for the obsolete MTQ-LAT3-B01.R2-SP. Both parts are manufactured by Multi-Tech Systems Inc. within the MultiTech Dragonfly™ series and maintain identical electrical, mechanical, and RF specifications across all critical parameters.

The MTQ-LAT3-B01.R2A-SP carries active product status, ensuring ongoing availability and manufacturer support. Both parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings. The substitute part provides additional documentation through specified internal IC (STM32F411RET) and memory configuration (512kB Flash, 96kB SRAM), offering enhanced traceability for system integration.

Selection of the MTQ-LAT3-B01.R2A-SP eliminates obsolescence risk while preserving full design compatibility with existing implementations of the MTQ-LAT3-B01.R2-SP.

Frequently Asked Questions (FAQ)

Q: Can the MTQ-LAT3-B01.R2A-SP be used as a direct replacement for the MTQ-LAT3-B01.R2-SP?
