MTSMC-H5.R2 Equivalent & Substitute Parts

Part Overview

The MTSMC-H5.R2 is a cellular 2G/3G HSPA+ transceiver module manufactured by Multi-Tech Systems Inc., designed for AT&T and T-Mobile networks. This module operates across multiple frequency bands (850MHz, 900MHz, 1.7GHz, 1.8GHz, 1.9GHz, 2.1GHz) and features USB serial interface connectivity with U.FL antenna connector. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSMC-H5.R2 is determined by the following critical parameters:

Voltage Supply Compatibility: Both main and substitute parts must operate within the 3.3V ~ 5V range to ensure direct integration into existing power distribution systems.

Antenna Interface: U.FL connector requirement ensures mechanical and electrical compatibility with existing antenna assemblies and PCB layouts.

Serial Interface: USB connectivity is required to maintain communication protocol compatibility with host systems.

Frequency Band Coverage: Substitute parts must support the same or overlapping frequency bands (850MHz, 900MHz, 1.7GHz, 1.8GHz, 1.9GHz, 2.1GHz) to maintain network compatibility.

Thermal Operating Range: The substitute must operate within or exceed the -35°C ~ 85°C range to function in equivalent environmental conditions.

RoHS Compliance: ROHS3 compliance is mandatory for regulatory and supply chain continuity.

The MTSMC-L4E1.R1 is identified as a substitute based on shared voltage supply range, U.FL antenna interface, SocketModem® Cell series designation, ROHS3 compliance, and MSL 1 rating. However, this substitute introduces protocol and frequency band differences that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The MTSMC-H5.R2 is obsolete. The MTSMC-L4E1.R1 shares identical voltage supply range, antenna interface, series designation, and compliance certifications. However, the substitute introduces three material differences: protocol upgrade from 2G/3G HSPA+ to 4G LTE CAT-3, mounting type change from surface mount to through hole, and expanded frequency band coverage.

Product Status Consideration: The MTSMC-L4E1.R1 maintains active product status, ensuring ongoing manufacturer support and supply chain availability. The MTSMC-H5.R2 obsolete status creates long-term sourcing risk.

Compliance Continuity: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental handling requirements without modification.

Thermal Performance: The MTSMC-L4E1.R1 extends the lower operating temperature limit to -40°C, providing enhanced cold-weather performance compared to the original -35°C specification.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L4E1.R1 directly replace the MTSMC-H5.R2 in existing designs?

A: Direct replacement requires evaluation of three factors: (1) PCB layout compatibility—the substitute uses through-hole mounting versus surface mount, requiring physical redesign; (2) protocol compatibility—the substitute operates on 4G LTE CAT-3 instead of 2G/3G HSPA+, requiring network operator support verification; (3) frequency band alignment—overlapping bands (850MHz, 900MHz, 1.8GHz, 2.1GHz) are present, but the substitute adds 700MHz and 2.6GHz coverage.

Q: What is the primary reason for substitution?

A: The MTSMC-H5.R2 is classified as obsolete. The MTSMC-L4E1.R1 is the equivalent active product from the same manufacturer and series, ensuring continued availability and support.

Q: Are there voltage supply compatibility concerns?

A: No. Both parts operate within the identical 3.3V ~ 5V supply range, eliminating power distribution modifications.

Q: Does the antenna interface remain compatible?

A: Yes. Both parts use U.FL connectors, maintaining mechanical and electrical compatibility with existing antenna assemblies.

Q: What mounting considerations apply?

A: The MTSMC-H5.R2 uses surface mount technology, while the MTSMC-L4E1.R1 uses through-hole mounting. PCB layout redesign is required for substitution.

Q: Are there serial interface differences?

A: Yes. The MTSMC-H5.R2 uses USB serial interface, while the MTSMC-L4E1.R1 uses serial interface. Host system communication protocol verification is necessary.

Q: Do compliance certifications remain equivalent?

A: Yes. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, satisfying regulatory and environmental handling requirements.
