Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Manufacturer: Multi-Tech Systems Inc.
• Series: SocketModem® Cell
• Frequency Bands: 700MHz, 850MHz, 1.7GHz, 1.9GHz
• Serial Interface: USB
• Antenna Connector: U.FL Through Hole
• Voltage Supply Range: 3.3V ~ 5V
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: Module

Secondary Compatibility Criteria:

• Current consumption (Receiving/Transmitting): 32mA
• Data Rate: 10Mbps
• RoHS Compliance: ROHS3 Compliant

The MTSMC-LAT3-U.R2A qualifies as a direct substitute based on matching all primary compatibility criteria. The protocol difference (CAT-3 versus CAT-1) represents a functional variation within the same product family, with both supporting the required frequency bands and network operators.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSMC-LAT3-U.R2 and MTSMC-LAT3-U.R2A are classified as obsolete products. Selection between these parts should be based on:

Compliance & Certification:

• Both parts maintain ROHS3 compliance
• Both carry MSL rating of 1 (Unlimited)
• Both are subject to ECCN 5A992C export classification

Packaging Consideration:

• MTSMC-LAT3-U.R2: Standard packaging (unspecified)
• MTSMC-LAT3-U.R2A: Bag packaging

Protocol Capability:

• MTSMC-LAT3-U.R2: LTE CAT-3 support
• MTSMC-LAT3-U.R2A: LTE CAT-1 support

Both parts support identical frequency bands, voltage ranges, current consumption, and operating temperature specifications. The choice between CAT-3 and CAT-1 protocol support depends on network requirements and system design specifications.

Frequently Asked Questions (FAQ)

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

A: Yes, from an electrical and mechanical standpoint. Both parts share identical voltage supply ranges (3.3V ~ 5V), current consumption (32mA receive/transmit), frequency band support (700MHz, 850MHz, 1.7GHz, 1.9GHz), USB serial interface, U.FL antenna connector, through-hole mounting, and operating temperature range (-40°C ~ 85°C). The protocol difference (CAT-3 versus CAT-1) represents a functional variation that must be evaluated against specific network and application requirements.

Q: What is the significance of the protocol difference between CAT-3 and CAT-1?

A: CAT-3 and CAT-1 refer to LTE category classifications that define data throughput capabilities. Both versions support the same frequency bands and network operators (AT&T/T-Mobile). The selection between them depends on whether the application requires CAT-3 performance characteristics or if CAT-1 performance is sufficient.

Q: Are there packaging differences between these parts?

A: Yes. MTSMC-LAT3-U.R2 uses standard packaging, while MTSMC-LAT3-U.R2A is supplied in bag packaging. This may affect handling, storage, and integration procedures but does not impact electrical or mechanical compatibility.

Q: What does the obsolete product status mean for component selection?

A: Both parts are classified as obsolete, indicating they are no longer in active production. Component selection should prioritize available inventory and long-term supply chain considerations. Verify current stock availability through authorized distributors before finalizing procurement decisions.

Q: Are both parts RoHS compliant?

A: Yes, both MTSMC-LAT3-U.R2 and MTSMC-LAT3-U.R2A maintain ROHS3 compliance and carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
