MTSMC-L4E1.R1 Equivalent & Substitute Parts

Part Overview

The MTSMC-L4E1.R1 is a cellular and navigation 4G LTE CAT-3 transceiver module manufactured by Multi-Tech Systems Inc. as part of the SocketModem® Cell series. This RF TXRX module operates across multiple frequency bands (700MHz, 800MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz) with a maximum data rate of 150Mbps and supports serial interfaces. The module features U.FL through-hole antenna connectivity and operates within a supply voltage range of 3.3V to 5V across an extended temperature range of -40°C to 85°C. The product maintains Active status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, protocol support, and mechanical compatibility are maintained across the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSMC-L4E1.R1 is determined by strict equivalence across the following critical parameters:

Protocol and RF Performance: The substitute part must support 4G LTE CAT-3 protocol with equivalent data rate of 150Mbps and maintain compatibility with the primary frequency bands required for the application.

Electrical Compatibility: Supply voltage range of 3.3V to 5V and serial interface support must be maintained to ensure direct integration into existing circuit designs.

Mechanical and Connector Compatibility: Through-hole mounting type and U.FL antenna connector type are mandatory for physical and electrical interface compatibility.

Operating Environment: Operating temperature range of -40°C to 85°C and moisture sensitivity level of 1 (Unlimited) ensure functional reliability across specified environmental conditions.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status must be maintained for regulatory and supply chain continuity.

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

The MTSMC-L4E1.R2 qualifies as a substitute based on these criteria, with the following considerations: frequency band coverage differs slightly (absence of 1.8GHz band in the substitute), packaging format differs (Box versus Tray), and current specifications are provided for the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The MTSMC-L4E1.R1 remains the primary choice when all six frequency bands (700MHz, 800MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz) are required for the application. This part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute Selection: The MTSMC-L4E1.R2 is suitable as a substitute when application requirements do not mandate the 1.8GHz frequency band. Both parts maintain identical protocol support (4G LTE CAT-3), equivalent data rate (150Mbps), matching supply voltage range (3.3V to 5V), and identical operating temperature specifications (-40°C to 85°C). Both parts carry Active product status with ROHS3 compliance and REACH unaffected designation.

Packaging Consideration: The MTSMC-L4E1.R2 is supplied in Box packaging format compared to Tray packaging for the main part. This distinction affects inventory management and component handling but does not impact electrical or mechanical performance.

Regulatory Compliance: Both parts satisfy ROHS3 compliance requirements and maintain REACH unaffected status, ensuring regulatory continuity in supply chain and end-product certification.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L4E1.R2 be used as a direct replacement for the MTSMC-L4E1.R1?

A: The MTSMC-L4E1.R2 functions as a substitute when the 1.8GHz frequency band is not required by the application. Both parts support identical 4G LTE CAT-3 protocol, 150Mbps data rate, 3.3V to 5V supply voltage, serial interfaces, U.FL antenna connectivity, through-hole mounting, and -40°C to 85°C operating temperature range. Frequency band coverage is the primary differentiator.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: 4G LTE CAT-3 protocol support, 150Mbps data rate capability, 3.3V to 5V supply voltage range, serial interface support, and operating temperature range of -40°C to 85°C. These parameters ensure functional equivalence in circuit integration and performance.

Q: Does packaging format affect component functionality?

A: Packaging format (Tray versus Box) does not affect electrical or mechanical functionality. The difference impacts inventory management, component handling procedures, and storage logistics but does not influence performance, compatibility, or regulatory compliance.

Q: Are both parts suitable for extended temperature applications?

A: Both the MTSMC-L4E1.R1 and MTSMC-L4E1.R2 support the identical operating temperature range of -40°C to 85°C, making them suitable for extended temperature applications within this specification.

Q: What is the significance of the U.FL antenna connector type?

A: The U.FL connector type specifies the antenna interface standard for both parts. This connector type must match the antenna and PCB design to ensure proper RF signal transmission and reception. Both substitute parts maintain identical U.FL through-hole antenna connectivity.

Q: Do both parts maintain the same regulatory compliance status?

A: Both the MTSMC-L4E1.R1 and MTSMC-L4E1.R2 maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory compliance for supply chain and end-product certification requirements.

Q: What is the moisture sensitivity level for these modules?

A: Both parts carry a moisture sensitivity level of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or operational conditions.
