Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSMC-L4N1.R2 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Multi-Tech Systems Inc.
• Series: SocketModem® Cell
• RF Family/Standard: Cellular, Navigation
• Frequency Bands: 600MHz, 700MHz, 850MHz, 1.7GHz, 1.9GHz
• Voltage Supply Range: 3.3V ~ 5V
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 64-DIP Module, 45 Leads
• Antenna Type: U.FL connector

Compatible Variation Parameters:

• Protocol: Substitute parts may include enhanced protocol support (GNSS, GPS, LTE) beyond the base 4G LTE CAT-4 specification
• Serial Interfaces: Substitute parts may include additional interface options (UART, USB) beyond the base Serial interface
• Product Status: Substitute parts with "Active" product status are preferred for new applications and ongoing support

The MTSMC-L4N1.R3 meets all mandatory matching parameters and represents a direct functional equivalent with enhanced protocol capabilities and active product status.

Engineering Selection Recommendations

The MTSMC-L4N1.R3 is the direct substitute for the MTSMC-L4N1.R2 based on the following engineering criteria:

Product Status Alignment: The MTSMC-L4N1.R2 is designated "Not For New Designs," indicating end-of-life status. The MTSMC-L4N1.R3 carries "Active" product status, ensuring continued manufacturer support, availability, and technical documentation.

Electrical and Mechanical Compatibility: Both modules share identical voltage supply ranges (3.3V ~ 5V), operating temperature specifications (-40°C ~ 85°C), frequency band coverage, and data rate performance (150Mbps). The 64-DIP Module package with 45 leads and U.FL antenna connector configuration are identical, ensuring direct mechanical and electrical compatibility in existing PCB designs.

Protocol and Interface Enhancement: The MTSMC-L4N1.R3 extends protocol support to include explicit GPS and LTE designation alongside GNSS, and provides expanded serial interface options (UART, USB) compared to the base Serial interface of the MTSMC-L4N1.R2. These enhancements maintain backward compatibility while offering additional functionality for modern applications.

Regulatory Compliance: Both modules comply with ROHS3 standards and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L4N1.R3 be used as a direct replacement for the MTSMC-L4N1.R2 in existing designs?

A: Yes. The MTSMC-L4N1.R3 maintains identical electrical specifications (voltage supply, operating temperature, frequency bands, data rate), mechanical configuration (64-DIP Module, 45 leads, U.FL connector), and mounting type (through hole). The modules are pin-compatible and functionally equivalent.

Q: What are the differences between the MTSMC-L4N1.R2 and MTSMC-L4N1.R3?

A: The primary differences are product status and serial interface options. The MTSMC-L4N1.R2 is "Not For New Designs" with Serial interface only. The MTSMC-L4N1.R3 is "Active" with expanded UART and USB interface support. Protocol designation is also more explicit in the R3 variant (GNSS, GPS, LTE).

Q: Are there any PCB layout modifications required when substituting the MTSMC-L4N1.R3 for the MTSMC-L4N1.R2?

A: No PCB layout modifications are required. Both modules use identical 64-DIP Module packaging with 45 leads and U.FL through-hole antenna connector configuration. Direct socket substitution is supported.

Q: What is the significance of the "Not For New Designs" status on the MTSMC-L4N1.R2?

A: "Not For New Designs" indicates that Multi-Tech Systems Inc. has discontinued active development and support for this revision. The MTSMC-L4N1.R2 remains available for legacy system maintenance and repair, but the MTSMC-L4N1.R3 is recommended for all new applications requiring active manufacturer support and documentation.

Q: Do both modules support the same frequency bands?

A: Yes. Both the MTSMC-L4N1.R2 and MTSMC-L4N1.R3 operate across identical frequency bands: 600MHz, 700MHz, 850MHz, 1.7GHz, and 1.9GHz, with 150Mbps data rate performance.

Q: Are the power supply requirements identical between the two modules?

A: Yes. Both modules operate with identical voltage supply range of 3.3V ~ 5V and identical operating temperature range of -40°C ~ 85°C.

Q: What additional serial interfaces does the MTSMC-L4N1.R3 provide?

A: The MTSMC-L4N1.R3 provides UART and USB serial interfaces in addition to the base Serial interface, offering expanded connectivity options for modern host systems.
