Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSMC-LVW3-U.R4-SP is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Manufacturer: Multi-Tech Systems Inc.
• Series: SocketModem® Cell
• Package/Case: 64-DIP Module, 45 Leads
• Mounting Type: Through Hole
• Antenna Type: U.FL
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Compliance: ROHS3 Compliant

Functional Parameters:

• RF Family/Standard: Cellular
• Serial Interfaces: USB (minimum requirement)
• Voltage Supply Range: Must accommodate 3.3V ~ 5V or higher
• Data Rate: 10Mbps minimum

The MTSMC-L1G2D-U-SP qualifies as a direct substitute because it maintains identical package configuration, mounting type, antenna interface, operating temperature range, and RoHS compliance status. The substitute part extends frequency band coverage and protocol support while preserving core electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L1G2D-U-SP is the manufacturer-recommended substitute for the obsolete MTSMC-LVW3-U.R4-SP. Selection of this substitute is supported by the following engineering criteria:

Compliance and Certification: Both parts maintain ROHS3 compliance, ensuring regulatory alignment with environmental standards. The substitute part carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics compared to the main part.

Product Status: The main part is classified as obsolete, while the substitute is active. This status difference ensures continued availability, manufacturing support, and supply chain reliability for the substitute part.

Electrical and Mechanical Compatibility: The substitute maintains identical package configuration (64-DIP Module, 45 Leads), mounting type (Through Hole), antenna interface (U.FL), and operating temperature range (-40°C ~ 85°C). Voltage supply specification of 5V in the substitute accommodates the 3.3V ~ 5V range of the main part.

Functional Enhancement: The substitute extends frequency band coverage from three bands (700MHz, 1.7GHz, 1.9GHz) to nine bands (700MHz, 800MHz, 850MHz, 900MHz, 1.7GHz, 1.8GHz, 1.9GHz, 2.1GHz, 2.6GHz) and adds UART serial interface capability alongside USB, providing enhanced system integration flexibility.

Frequently Asked Questions (FAQ)

Q: Can the MTSMC-L1G2D-U-SP be used as a direct replacement for the MTSMC-LVW3-U.R4-SP in existing designs?

A: Yes. Both parts share identical package configuration (64-DIP Module, 45 Leads), through-hole mounting type, U.FL antenna interface, and operating temperature range (-40°C ~ 85°C). The substitute part is electrically and mechanically compatible with existing PCB layouts and connector interfaces designed for the main part.

Q: What are the key differences between these two modules?

A: The primary differences are: (1) Product status—the main part is obsolete while the substitute is active; (2) Frequency band coverage—the substitute supports nine bands compared to three in the main part; (3) Serial interfaces—the substitute adds UART capability in addition to USB; (4) Voltage supply specification—the substitute specifies 5V while the main part specifies 3.3V ~ 5V; (5) Moisture sensitivity level—the substitute carries an MSL rating of 1 (Unlimited).

Q: Are there any voltage supply considerations when substituting?

A: The main part operates across 3.3V ~ 5V, while the substitute specifies 5V operation. Systems designed for the main part operating at 3.3V should be evaluated to ensure compatibility with the substitute's 5V requirement. Systems already operating at 5V require no modification.

Q: Does the substitute support the same frequency bands as the main part?

A: The substitute supports all three frequency bands of the main part (700MHz, 1.7GHz, 1.9GHz) plus six additional bands (800MHz, 850MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz). This extended frequency coverage provides greater flexibility for multi-region deployment.

Q: What is the significance of the MSL rating difference?

A: The substitute carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity limitations during storage and handling. The main part does not specify an MSL rating. This difference favors the substitute for applications requiring extended shelf life or storage in variable humidity environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the MTSMC-LVW3-U.R4-SP and MTSMC-L1G2D-U-SP are ROHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.

Q: Can the substitute be used in applications requiring only the three frequency bands of the main part?

A: Yes. The substitute supports all three frequency bands of the main part (700MHz, 1.7GHz, 1.9GHz). Applications requiring only these bands can operate the substitute without modification, with the additional frequency bands remaining available for future expansion.
