MTSMC-LAT3-U.R2-SP Equivalent & Substitute Parts

Part Overview

The MTSMC-LAT3-U.R2-SP is a cellular 4G LTE CAT-3 transceiver module manufactured by Multi-Tech Systems Inc., designed for AT&T and T-Mobile networks. This through-hole module operates across 700MHz, 850MHz, 1.7GHz, and 1.9GHz frequency bands with USB serial interface connectivity and U.FL antenna connector. The product is classified as obsolete, necessitating identification of functionally compatible alternatives for ongoing system support and new designs requiring equivalent cellular connectivity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSMC-LAT3-U.R2-SP is determined by the following critical parameters:

Primary Compatibility Criteria:

• Cellular protocol family (4G LTE)
• Frequency band coverage (700MHz, 850MHz, 1.7GHz, 1.9GHz)
• Serial interface type (USB)
• Antenna connector type (U.FL)
• Mounting configuration (Through Hole)
• Voltage supply range (3.3V ~ 5V)
• Operating temperature range (-40°C ~ 85°C)
• Package form factor (Module)

The identified substitute MTSMC-LAT3-U.R2A-SP maintains compatibility across all primary criteria. While this substitute operates under 4G LTE CAT-1 protocol (compared to CAT-3 in the main part), both variants support identical frequency bands, USB interface, U.FL antenna connection, through-hole mounting, and equivalent electrical specifications. The CAT-1 to CAT-3 protocol difference reflects reduced data throughput capability in the substitute, which remains within the same product family and maintains full hardware and interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSMC-LAT3-U.R2-SP and MTSMC-LAT3-U.R2A-SP are classified as obsolete products. Selection between these parts should be based on application-specific data throughput requirements and inventory availability.

The MTSMC-LAT3-U.R2-SP (CAT-3) supports higher LTE category classification, suitable for applications requiring maximum data throughput within the 10Mbps specification. The MTSMC-LAT3-U.R2A-SP (CAT-1) provides equivalent hardware integration and interface compatibility with reduced protocol capability.

Both parts maintain ROHS3 compliance and identical electrical operating parameters. The substitute is available in bag packaging, whereas the main part packaging specification is not defined. For applications where protocol downgrade is acceptable and hardware integration is the primary concern, the MTSMC-LAT3-U.R2A-SP provides direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can MTSMC-LAT3-U.R2A-SP directly replace MTSMC-LAT3-U.R2-SP in existing designs?

A: Yes, from a hardware and interface perspective. Both modules share identical mounting type (through hole), antenna connector (U.FL), serial interface (USB), voltage supply range (3.3V ~ 5V), and operating temperature specifications (-40°C ~ 85°C). The primary difference is the LTE protocol category (CAT-1 vs. CAT-3), which affects maximum data throughput capability but does not impact physical or electrical compatibility.

Q: What is the significance of the LTE CAT-3 to CAT-1 protocol difference?

A: LTE category classification defines maximum theoretical data throughput. CAT-3 supports higher throughput than CAT-1. However, both parts specify identical 10Mbps data rate in this product line. Applications limited to 10Mbps operation experience no functional difference between these protocol categories.

Q: Are there packaging differences between these parts?

A: The MTSMC-LAT3-U.R2-SP packaging is not specified in available documentation. The MTSMC-LAT3-U.R2A-SP is supplied in bag packaging. Confirm packaging requirements with your procurement process before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MTSMC-LAT3-U.R2-SP and MTSMC-LAT3-U.R2A-SP are ROHS3 compliant with MSL rating of 1 (Unlimited). Both support identical frequency bands (700MHz, 850MHz, 1.7GHz, 1.9GHz) for AT&T and T-Mobile networks.

Q: Why are both parts classified as obsolete?

A: Both modules are end-of-life products from Multi-Tech Systems Inc. Obsolete status indicates no further manufacturing or support. Substitution decisions should account for long-term availability and consider alternative current-generation cellular modules if extended product lifecycle is required.
