LG69TAPMD Navigation GNSS Transceiver Module – Equivalent & Substitute Parts

Part Overview

The LG69TAPMD is a multi-constellation navigation transceiver module manufactured by Quectel, supporting BeiDou, Galileo, GLONASS, and GPS protocols. This surface-mount module integrates GNSS reception capabilities without an integrated antenna. The LG69TAPMD is classified as Obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across navigation protocols, serial interface standards, and physical mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LG69TAPMD is determined by the following critical parameters:

Protocol Compatibility: The substitute part must support all four navigation protocols—BeiDou, Galileo, GLONASS, and GPS—to maintain functional equivalence in multi-constellation GNSS applications.

Serial Interface Support: The substitute must provide I2C, SPI, and UART interfaces to ensure compatibility with existing host processor communication architectures.

Mounting and Package: Surface-mount technology and module-level packaging are required to maintain PCB integration compatibility.

Antenna Configuration: The substitute must also operate without an integrated antenna, requiring external antenna connection.

RoHS Compliance: The substitute part must maintain RoHS compliance status for regulatory consistency.

The LG69TAPGMD meets all substitution criteria as an active product from the same manufacturer (Quectel) within the LG69T series, providing direct functional replacement capability.

The LG69TAPGMD maintains active product status, ensuring continued availability and manufacturer support.

Compliance Considerations:

The LG69TAPMD is RoHS Compliant with MSL 3 moisture sensitivity classification. The LG69TAPGMD is the active equivalent within the LG69T series. Both parts are surface-mount modules without integrated antennas, supporting identical host processor integration patterns.

Availability:

The LG69TAPMD is classified as Obsolete with 1,032 units in current inventory. The LG69TAPGMD is Active with 657 units in current inventory, providing ongoing supply assurance for new production and design transitions.

Frequently Asked Questions (FAQ)

Q: Can the LG69TAPGMD directly replace the LG69TAPMD in existing designs?

A: Yes. Both parts support identical navigation protocols (BeiDou, Galileo, GLONASS, GPS, GNSS) and serial interfaces (I2C, SPI, UART). Both are surface-mount modules without integrated antennas. The LG69TAPGMD is the manufacturer-recommended substitute.

Q: What is the difference between the LG69TAPMD and LG69TAPGMD package designations?

A: The LG69TAPMD is specified as a Module package type. The LG69TAPGMD is specified as a 54-SMD Module package type. Both are surface-mount configurations suitable for PCB integration.

Q: Are there electrical performance differences between these parts?

A: The LG69TAPGMD provides specified electrical parameters including 921.6 kbps data rate, −160 dBm sensitivity, 3.0 V to 3.6 V supply voltage, and 360 mA receive/transmit current. The LG69TAPMD does not have these parameters specified in available documentation. Both parts support identical navigation protocols and serial interfaces.

Q: Why is the LG69TAPMD classified as Obsolete?

A: The LG69TAPMD has reached end-of-life status. The LG69TAPGMD is the active replacement within the LG69T series, providing equivalent functionality with ongoing manufacturer support.

Q: What are the moisture handling requirements for these modules?

A: The LG69TAPMD is classified as MSL 3 (168 Hours), indicating moisture sensitivity level 3 with a floor life of 168 hours after moisture exposure. Standard moisture control procedures apply during storage and handling.

Q: Do both parts require external antenna connections?

A: Yes. Both the LG69TAPMD and LG69TAPGMD are specified as Antenna Not Included. External antenna connection is required for GNSS signal reception.
