Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSMC-L4G1-U-SP is determined by strict equivalence across the following critical parameters:

RF and Protocol Compatibility: The substitute part must support the identical 4G LTE CAT-4 protocol with AT&T and Verizon network compatibility. All frequency bands (700MHz through 2.6GHz) must be supported without exception.

Electrical Specifications: The substitute must operate within the same voltage supply range (3.3V ~ 5V) and maintain identical current consumption specifications for both receiving (46mA) and transmitting (46mA) modes.

Physical and Interface Compatibility: The substitute must feature the same U.FL through-hole antenna connector type and through-hole mounting configuration to ensure mechanical compatibility with existing PCB designs.

Data Rate and Serial Interface: The substitute must maintain the 150Mbps data rate specification and USB serial interface to preserve system-level communication protocols.

Manufacturer and Series Consistency: The substitute is sourced from the same manufacturer (Multi-Tech Systems Inc.) within the SocketModem® Cell series, ensuring firmware compatibility and design continuity.
