Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSMC-LAT3.R2A-SP is determined by the following critical parameters:

Mechanical Compatibility:

• Mounting type: Through Hole
• Antenna connector: U.FL
• Package form factor: Module

Electrical Compatibility:

• Supply voltage range: 3.3V ~ 5V
• Operating temperature range: -40°C ~ 85°C
• Serial interface capability

Regulatory Compliance:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1

Functional Requirements:

• Cellular RF transceiver capability
• SocketModem® Cell series compatibility
• Multi-Tech Systems Inc. manufacture

The MTSMC-L1G2D-SP qualifies as a substitute part because it maintains compatibility across all mechanical mounting parameters, operates within the same voltage and temperature ranges, maintains identical regulatory compliance certifications, and is manufactured by the same supplier within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L1G2D-SP is an active substitute for the obsolete MTSMC-LAT3.R2A-SP based on the following engineering criteria:

Product Status Alignment: The MTSMC-L1G2D-SP maintains active product status with Multi-Tech Systems Inc., ensuring continued availability and support compared to the obsolete MTSMC-LAT3.R2A-SP.

Regulatory Compliance: Both parts maintain identical RoHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent component substitution.

Mechanical and Electrical Compatibility: Both modules feature through-hole mounting, U.FL antenna connectors, and operate within the same temperature range (-40°C to 85°C). The MTSMC-L1G2D-SP operates at 5V supply voltage, which falls within the 3.3V to 5V range of the original part.

Functional Enhancement: The MTSMC-L1G2D-SP extends frequency band coverage to include 800MHz, 900MHz, 1.8GHz, 2.1GHz, and 2.6GHz, and adds GNSS and GPS protocol support alongside LTE capability. The substitute part maintains the 10Mbps data rate and adds UART and USB serial interface options beyond the serial interface of the original part.

Series Continuity: Both parts belong to the SocketModem® Cell series, maintaining design and integration consistency within Multi-Tech Systems Inc. product architecture.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L1G2D-SP directly replace the MTSMC-LAT3.R2A-SP in existing designs?

A: The MTSMC-L1G2D-SP is mechanically and electrically compatible as a substitute. Both modules feature identical through-hole mounting, U.FL antenna connectors, and operate within the same temperature range. The substitute part operates at 5V, which is within the 3.3V to 5V supply range of the original part. However, the substitute part features a 64-DIP module form factor with 45 leads compared to the generic module package of the original part, requiring physical layout verification.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), frequency band coverage, and protocol support. The MTSMC-L1G2D-SP adds 800MHz, 900MHz, 1.8GHz, 2.1GHz, and 2.6GHz frequency bands and includes GNSS and GPS protocol support. The substitute part also provides UART and USB serial interfaces in addition to the serial interface of the original part.

Q: Are there any supply voltage considerations when substituting?

A: The MTSMC-LAT3.R2A-SP operates at 3.3V to 5V, while the MTSMC-L1G2D-SP operates at 5V. Designs using 3.3V supply voltage with the original part require voltage regulation or conversion to 5V for the substitute part.

Q: Do both parts maintain the same regulatory compliance?

A: Yes. Both the MTSMC-LAT3.R2A-SP and MTSMC-L1G2D-SP are ROHS3 compliant, REACH unaffected, and maintain Moisture Sensitivity Level 1 (unlimited). Regulatory compliance is equivalent between the two parts.

Q: What is the significance of the package form factor difference?

A: The MTSMC-LAT3.R2A-SP uses a generic module package, while the MTSMC-L1G2D-SP uses a 64-DIP module with 45 leads. This difference requires physical layout and footprint verification to ensure the substitute part fits within the existing PCB design and connector arrangement.

Q: Are the current consumption specifications comparable?

A: The MTSMC-LAT3.R2A-SP specifies 20mA for both receiving and transmitting modes. The MTSMC-L1G2D-SP does not provide current consumption specifications in the available data. Power budget analysis should be performed independently for the substitute part.

Q: Can the extended frequency band support of the MTSMC-L1G2D-SP cause compatibility issues?

A: The extended frequency band coverage of the MTSMC-L1G2D-SP is a functional enhancement that does not create backward compatibility issues. Designs operating within the original 700MHz, 850MHz, 1.7GHz, and 1.9GHz bands will function identically with the substitute part.
