LC86LIAMD Equivalent & Substitute Parts

Part Overview

The LC86LIAMD is a Navigation GNSS Transceiver Module manufactured by Quectel, designed for multi-constellation satellite positioning applications. This module integrates Galileo, GLONASS, GPS, and GNSS protocols with a ceramic patch antenna in a compact surface mount package. The LC86LIAMD is classified as obsolete, making identification of equivalent substitute components essential for ongoing system support, design updates, and procurement continuity. Substitute parts must maintain functional compatibility across RF performance, electrical specifications, and mechanical form factors to ensure seamless integration into existing or redesigned applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LC86LIAMD are identified based on strict alignment with the following critical parameters:

RF Protocol Compatibility: The substitute must support the same navigation constellation standards (Galileo, GLONASS, GPS, GNSS) to maintain functional equivalence in multi-constellation positioning applications.

Frequency Alignment: Operating frequencies of 1.575GHz and 1.601GHz are fundamental to GNSS receiver operation. Substitute parts must operate within these frequency bands.

Electrical Interface: UART serial communication is the specified interface standard. Substitute parts must maintain this interface for direct integration without protocol conversion.

Antenna Configuration: The integrated ceramic patch antenna is a key mechanical and electrical characteristic. Substitute parts must retain this antenna type to preserve RF performance and form factor compatibility.

Power Supply Range: The 3V to 4.3V supply voltage range defines the power delivery requirements. Substitute parts must operate within this range.

Environmental Specifications: Operating temperature range of -40°C to 85°C and Moisture Sensitivity Level 3 establish the reliability and handling requirements for the application environment.

Packaging and Mounting: Surface mount 12-SMD module packaging ensures mechanical compatibility with existing PCB designs and assembly processes.

The LC86GABMD meets all these criteria and is classified as the manufacturer-recommended substitute for the obsolete LC86LIAMD.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LC86LIAMD is classified as obsolete, while the LC86GABMD is active. For new designs, ongoing production, or system refreshes, the LC86GABMD is the appropriate selection to ensure long-term component availability and manufacturer support.

Compliance and Certification: Both parts are manufactured by Quectel and share the same base product family (LC86 series). The LC86GABMD maintains active product status, ensuring continued compliance with current regulatory standards and manufacturing quality assurance protocols.

Packaging Transition: The main part is supplied in Cut Tape (CT) & Digi-Reel® format, while the substitute is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical compatibility but may require adjustment to procurement and assembly processes.

Inventory and Supply Chain: The LC86GABMD has confirmed active inventory (798 Pcs New Original In Stock) and active product status, providing reliable supply chain continuity compared to the obsolete LC86LIAMD.

Frequently Asked Questions (FAQ)

Q: Can the LC86GABMD directly replace the LC86LIAMD in existing designs?

A: The LC86GABMD is the manufacturer-recommended substitute for the LC86LIAMD. Both are surface mount 12-SMD modules from the Quectel LC86 family. Direct replacement is supported at the mechanical and electrical interface level. Verify that your PCB layout and assembly process accommodate the Tape & Reel (TR) packaging format of the substitute.

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

A: The primary difference is product status: LC86LIAMD is obsolete, while LC86GABMD is active. The packaging format differs (Cut Tape & Digi-Reel versus Tape & Reel). Both parts are surface mount modules from the same manufacturer and product family.

Q: Are there any electrical performance differences?

A: Both parts are from the Quectel LC86 navigation transceiver module family. The substitute maintains compatibility with the RF protocols, frequency bands, and serial interface specifications of the main part.

Q: What should I consider when transitioning from LC86LIAMD to LC86GABMD?

A: Confirm that your assembly process and component handling procedures are compatible with Tape & Reel (TR) packaging. Verify moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Confirm that your power supply and interface connections align with the module specifications.

Q: Is the LC86GABMD RoHS compliant?

A: The LC86LIAMD is confirmed RoHS compliant. RoHS compliance status for the LC86GABMD is not specified in the available substitute data. Contact the manufacturer or authorized distributor for current RoHS certification documentation.

Q: Can I use the LC86GABMD in new product designs?

A: Yes. The LC86GABMD is classified as active product status, making it suitable for new designs, production runs, and long-term system support. The active status ensures ongoing manufacturer support and component availability.
