Key Parameters

Substitute Part Grouping Explanation

The GT-88 qualifies as a substitute for the GT-86 based on the following alignment of critical parameters:

Common Functional Criteria:

• Both components are RF receiver modules manufactured by Kaga Electronics USA
• Both support GNSS and GPS protocols (GT-88 extends support to Galileo and GLONASS)
• Both utilize 24-LCC package configuration
• Both are surface mount devices
• Both maintain RoHS compliance and MSL 3 rating

Substitution Logic: The GT-88 represents an active, functionally enhanced alternative. While the GT-86 operates at a fixed 1.575GHz frequency, the GT-88 operates across a broader frequency range (10Hz ~ 40MHz), encompassing the GT-86 operating point. The GT-88 provides superior sensitivity (-148dBm) and expanded satellite constellation support, making it suitable for applications requiring the GT-86's core GPS/GNSS reception capability.

Parameter Comparison

Engineering Selection Recommendations

GT-88 as Primary Substitute: The GT-88 is the designated substitute for the GT-86. Both components maintain identical RoHS compliance and MSL ratings, ensuring equivalent environmental and regulatory standing. The GT-88's active product status provides supply chain continuity and manufacturing support, addressing the obsolescence of the GT-86. The 24-LCC package compatibility ensures mechanical fit within existing PCB layouts designed for the GT-86.

Compliance Alignment: Both parts are RoHS compliant with MSL 3 classification, supporting identical moisture handling and storage protocols. The GT-88's ECCN classification (7A994) reflects its active status and broader satellite constellation support compared to the GT-86's obsolete designation.

Frequently Asked Questions (FAQ)

Q: Can the GT-88 directly replace the GT-86 in existing designs? A: The GT-88 shares the 24-LCC package configuration and surface mount characteristics with the GT-86. Both components support GPS and GNSS protocols. However, design validation is necessary to confirm compatibility with existing firmware, interface protocols, and power supply specifications, as the GT-88 specifies UART data interface and 3.3V supply voltage.

Q: What are the key differences between GT-86 and GT-88? A: The GT-88 operates across a broader frequency range (10Hz ~ 40MHz versus 1.575GHz), provides specified sensitivity (-148dBm), supports additional satellite constellations (Galileo and GLONASS), and includes defined operating temperature range (-40°C ~ 85°C) and supply voltage (3.3V). The GT-86 specifications for these parameters are not provided in the reference data.

Q: Are both parts RoHS compliant? A: Yes. Both the GT-86 and GT-88 are RoHS compliant with identical MSL 3 (168 Hours) moisture sensitivity ratings.

Q: What is the package compatibility status? A: Both components use 24-LCC packaging. The GT-88 is specified as 24-LCC (16x12.2) in SMD module form. Mechanical footprint compatibility should be confirmed during design transition.

Q: Why is the GT-86 obsolete? A: The GT-86 is classified as obsolete by the manufacturer. The GT-88 represents the active product line continuation for GPS/GNSS receiver applications from Kaga Electronics USA.
