Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSMC-L4G1-U 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 specification for AT&T and Verizon networks and operate across all specified frequency bands (700MHz through 2.6GHz).

Electrical Interface Requirements: The substitute must provide USB serial interface connectivity, operate within the 3.3V to 5V supply voltage range, and maintain identical current consumption specifications (46mA receiving and transmitting).

Physical and Mechanical Compatibility: The substitute must feature U.FL antenna connector configuration, through-hole mounting type, and module package format to ensure direct integration into existing PCB designs.

Environmental and Compliance Standards: The substitute must maintain ROHS3 compliance and MSL 1 rating to meet regulatory and manufacturing requirements.

Series Continuity: The substitute must belong to the SocketModem® Cell series to ensure firmware and software compatibility.

Engineering Selection Recommendations

MTSMC-L4G1-U.R1A as Primary Substitute:

The MTSMC-L4G1-U.R1A is the direct equivalent substitute for the obsolete MTSMC-L4G1-U. This part maintains complete electrical, mechanical, and functional parity across all specified parameters. The substitute carries Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity.

Both parts share identical RF specifications, protocol support, frequency band coverage, data rate capability, and power consumption characteristics. The electrical interface (USB), antenna connector type (U.FL), mounting configuration (through-hole), and environmental operating range (-40°C to 85°C) are fully compatible.

Compliance certifications are equivalent: both parts maintain ROHS3 compliance and MSL 1 rating. The substitute includes Box packaging, providing enhanced protection during storage and transportation compared to the original part specification.

The MTSMC-L4G1-U.R1A is suitable for direct replacement in all applications where the MTSMC-L4G1-U was originally specified. No design modifications, firmware updates, or software reconfiguration are required for integration.
