LC79DAMD Equivalent & Substitute Parts

Part Overview

The LC79DAMD is a Navigation BeiDou, Galileo, GLONASS, GPS, GNSS Transceiver Module manufactured by Quectel. This surface mount RF transceiver module integrates multi-constellation satellite navigation reception capabilities across four frequency bands: 1.176GHz, 1.561GHz, 1.575GHz, and 1.602GHz. The module operates with a data rate of 921.6kbps and provides sensitivity of -163dBm, supporting multiple serial interfaces including I2C, SPI, and UART.

The LC79DAMD carries a product status designation of "Not For New Designs," indicating that this component is no longer recommended for new development projects. Identifying equivalent substitute parts is necessary to ensure continued component availability, access to active product support, and compliance with current manufacturing standards for ongoing or new applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC79DAMD is determined by alignment across the following critical parameters:

RF Functionality & Protocol Compatibility: The substitute part must support the same navigation protocols (BeiDou, Galileo, GLONASS, GPS, GNSS) and operate across the same frequency bands (1.176GHz, 1.561GHz, 1.575GHz, 1.602GHz) to maintain functional equivalence in satellite navigation applications.

Electrical Performance: The substitute must maintain compatible voltage supply requirements (1.7V ~ 1.9V), data rate capability (921.6kbps), and sensitivity performance (-163dBm) to ensure proper operation within existing system designs.

Serial Interface Support: The substitute must provide the same serial communication interfaces (I2C, SPI, UART) to ensure compatibility with host processor connections and firmware implementations.

Physical & Environmental Specifications: The substitute must be compatible with surface mount assembly processes, operate across the same temperature range (-40°C ~ 85°C), and meet the same moisture sensitivity classification (MSL 3) to ensure reliability in production and field deployment.

Regulatory Compliance: The substitute must maintain RoHS compliance status to satisfy environmental and regulatory requirements.

Product Status: Substitutes with "Active" product status are prioritized to ensure long-term availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs: The LC79DAMD remains available with 2002 units in current inventory. Existing production systems utilizing this component may continue operation without immediate substitution requirements.

For New Development: The LC79HALMD is the designated substitute for new design implementations. This component carries an "Active" product status, indicating ongoing manufacturer support, continued availability, and alignment with current design practices. The LC79HALMD is manufactured by Quectel and maintains the same packaging format (Tape & Reel) and mounting technology (Surface Mount) as the LC79DAMD, facilitating direct integration into existing assembly processes.

Compliance Considerations: Both components are RoHS compliant and suitable for applications requiring environmental regulatory adherence. The transition from LC79DAMD to LC79HALMD does not introduce compliance complications.

Inventory Planning: With 2300 units of LC79HALMD currently in stock, supply continuity is supported for production ramp-up and ongoing manufacturing requirements.

Frequently Asked Questions (FAQ)

Q: Can the LC79HALMD directly replace the LC79DAMD in existing circuit designs?

A: The LC79HALMD is the manufacturer-designated substitute for the LC79DAMD. Both components are Quectel navigation transceiver modules with surface mount packaging and Tape & Reel format. Direct substitution is supported for applications requiring equivalent navigation functionality.

Q: What is the significance of the "Not For New Designs" status on the LC79DAMD?

A: This designation indicates that Quectel has transitioned the LC79DAMD to legacy status and recommends the LC79HALMD for new development projects. Existing designs may continue using the LC79DAMD, but new implementations should utilize the LC79HALMD to ensure long-term manufacturer support and component availability.

Q: Are there any packaging or assembly differences between these components?

A: Both the LC79DAMD and LC79HALMD utilize identical packaging formats (Tape & Reel) and mounting technology (Surface Mount). Assembly processes and handling procedures remain consistent between the two components.

Q: How does product status affect component selection?

A: Product status reflects the manufacturer's support lifecycle. The LC79HALMD's "Active" status ensures continued availability, technical support, and manufacturing consistency. The LC79DAMD's "Not For New Designs" status indicates transition to legacy support, making the LC79HALMD the preferred choice for new applications.

Q: What inventory considerations apply to these components?

A: The LC79DAMD has 2002 units in stock, while the LC79HALMD has 2300 units available. Both components are available as new original stock in Tape & Reel packaging, supporting immediate procurement for production requirements.
