Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTQ-LSP3-B02 is based on the following critical parameters that must align between the main part and substitute candidates:

Mandatory Alignment Parameters:

• Manufacturer: Multi-Tech Systems Inc.
• Series: MultiTech Dragonfly™
• Mounting Type: Chassis Mount
• Frequency Bands: 700MHz, 850MHz, 1.7GHz, 1.9GHz
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: Module

Functional Compatibility Parameters:

• RF Family/Standard: Cellular
• Antenna Configuration: Antenna Not Included
• Serial Interface Support: UART, USB (minimum required interfaces present in substitutes)

The substitute parts MTQ-LNA7-B02.R1A and MTQ-LNA7-B02.R2 satisfy these alignment criteria. Both are active products from the same manufacturer and series, operate across identical frequency bands, maintain the same mounting configuration, and support the required operating temperature range. Both substitutes feature improved data rate capability (150Mbps versus 10Mbps) and reduced current consumption during receive and transmit operations.

Parameter Comparison

Engineering Selection Recommendations

MTQ-LNA7-B02.R1A and MTQ-LNA7-B02.R2 Selection Basis:

Both substitute parts are active products with current manufacturing support, addressing the obsolescence status of the MTQ-LSP3-B02. The substitutes maintain identical frequency band coverage and operating temperature specifications, ensuring compatibility with existing system designs.

The substitute parts demonstrate enhanced compliance posture through ROHS3 certification and REACH compliance status, supporting regulatory requirements for new deployments and system updates. Both substitutes feature improved power efficiency with reduced current consumption (28mA versus 33mA) during receive and transmit operations.

The voltage supply range of 3.3V to 5V in the substitute parts provides greater design flexibility compared to the fixed 5V requirement of the main part. The data rate improvement from 10Mbps to 150Mbps represents a significant performance enhancement for applications requiring higher throughput.

The substitutes incorporate U.FL antenna connectors, providing standardized antenna interface options not explicitly specified in the main part. Serial interface support includes UART and USB, which are the primary interfaces required for most cellular transceiver applications.

MTQ-LNA7-B02.R1A and MTQ-LNA7-B02.R2 are functionally equivalent for cellular transceiver applications within the specified frequency bands and operating conditions.

Frequently Asked Questions (FAQ)

Q: Why is the MTQ-LSP3-B02 classified as obsolete?

A: The MTQ-LSP3-B02 has reached end-of-life status and is no longer in active production. Multi-Tech Systems Inc. has transitioned to the MTQ-LNA7-B02 series as the current product line for cellular transceiver modules in the Dragonfly™ family.

Q: Are the substitute parts MTQ-LNA7-B02.R1A and MTQ-LNA7-B02.R2 interchangeable?

A: Both substitute parts are functionally equivalent for cellular transceiver applications. They share identical frequency band support, operating temperature range, mounting configuration, and core serial interface capabilities. Selection between the two substitutes depends on specific inventory availability and procurement requirements.

Q: What are the key differences between the MTQ-LSP3-B02 and its substitutes?

A: The primary differences are: (1) Protocol support—the main part supports GNSS/LTE while substitutes support 4G LTE CAT-1 and HSPA+; (2) Data rate—substitutes provide 150Mbps versus 10Mbps; (3) Serial interfaces—substitutes support UART and USB while the main part also includes I2C and SPI; (4) Antenna connector—substitutes feature U.FL connectors; (5) Voltage supply—substitutes accept 3.3V to 5V versus fixed 5V; (6) Current consumption—substitutes require 28mA versus 33mA.

Q: Can the MTQ-LSP3-B02 be directly replaced with MTQ-LNA7-B02.R1A or MTQ-LNA7-B02.R2 in existing designs?

A: Direct replacement requires verification of serial interface requirements. If the design utilizes I2C or SPI interfaces, alternative solutions must be evaluated since the substitute parts support only UART and USB. Voltage supply compatibility must be confirmed; designs requiring fixed 5V operation are compatible with the substitutes' 3.3V to 5V range. Antenna connector differences (U.FL in substitutes) require mechanical and electrical interface assessment.

Q: What compliance advantages do the substitute parts offer?

A: The substitute parts MTQ-LNA7-B02.R1A and MTQ-LNA7-B02.R2 are ROHS3 compliant and REACH unaffected, supporting regulatory requirements for new product designs and system updates. The main part does not specify these compliance certifications.

Q: Are there inventory considerations for selecting between the substitutes?

A: MTQ-LNA7-B02.R1A has 1082 pieces in stock while MTQ-LNA7-B02.R2 has 839 pieces in stock. Both represent active products with ongoing manufacturing support. Inventory levels should be evaluated against project timelines and volume requirements.

Q: What is the significance of the U.FL antenna connector in the substitute parts?

A: The U.FL connector is a standardized miniature RF connector widely used in cellular modules. This provides access to a broader range of compatible antenna options compared to the main part's unspecified antenna configuration. The U.FL interface enables modular antenna selection and replacement.

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

A: Yes. Both MTQ-LNA7-B02.R1A and MTQ-LNA7-B02.R2 operate across 700MHz, 850MHz, 1.7GHz, and 1.9GHz frequency bands, identical to the MTQ-LSP3-B02. This ensures compatibility with existing RF system designs and network infrastructure.
