Equivalent & Substitute Parts: Sierra Wireless AirLink 1103872

Part Overview

The Sierra Wireless AirLink 1103872 is an RF transceiver module designed for GPS navigation applications, featuring a 1.575GHz integrated ceramic patch antenna in a surface mount configuration. This module operates as part of the XA - AirPrime® series and delivers UART serial interface connectivity with 115.2kbps data rate capability.

The 1103872 is classified as an obsolete product. Locating equivalent substitute components is necessary for ongoing system support, maintenance, and component procurement when original inventory becomes unavailable. Substitute parts must maintain electrical and mechanical compatibility across critical parameters including frequency, data rate, supply voltage, sensitivity, serial interface type, antenna configuration, and mounting specifications.

• Frequency: 1.575GHz
• Data Rate: 115.2kbps
• Sensitivity: -165dBm
• Serial Interface: UART
• Antenna Type: Integrated, Ceramic Patch
• Voltage Supply Range: 3V ~ 4.3V
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C

The Quectel L80RE-M37 satisfies all critical electrical parameters required for GPS transceiver module substitution. Both components operate at identical frequency, data rate, sensitivity, and supply voltage specifications. Both feature UART serial interfaces, integrated ceramic patch antennas, and surface mount configurations suitable for equivalent circuit board integration. Operating temperature ranges are identical across both components.

Parameter Comparison

Engineering Selection Recommendations

Quectel L80RE-M37 as Substitute for Sierra Wireless AirLink 1103872:

The Quectel L80RE-M37 provides electrical equivalence across all critical GPS transceiver parameters. Both components operate at 1.575GHz with -165dBm sensitivity, 115.2kbps data rate, and UART serial interface connectivity. Supply voltage ranges, operating temperature specifications, and antenna configurations are identical.

The L80RE-M37 carries ROHS3 compliance and REACH unaffected status, indicating current regulatory alignment. The original 1103872 is classified as obsolete, whereas the L80RE-M37 is designated as not for new designs, reflecting its availability in current inventory (1364 pieces in stock versus 962 pieces for the original part).

Package configuration differs between components: the 1103872 uses a 24-SMD module while the L80RE-M37 uses a 12-SMD module. This difference requires circuit board layout evaluation to confirm physical fit and pin compatibility. Moisture sensitivity levels differ (MSL 4 versus MSL 3), affecting storage and handling protocols during component procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the Quectel L80RE-M37 directly replace the Sierra Wireless AirLink 1103872 in existing designs?

A: Electrical substitution is supported across all critical GPS transceiver parameters including frequency, data rate, sensitivity, supply voltage, and serial interface specifications. Physical package differences (24-SMD versus 12-SMD module configuration) require circuit board layout verification to confirm pin-to-pin compatibility and mechanical fit before implementation.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is established through matching protocol (GPS), frequency (1.575GHz), data rate (115.2kbps), sensitivity (-165dBm), serial interface (UART), antenna type (integrated ceramic patch), supply voltage range (3V ~ 4.3V), and operating temperature range (-40°C ~ 85°C).

Q: How do the package configurations differ between these components?

A: The Sierra Wireless AirLink 1103872 is packaged as a 24-SMD module, while the Quectel L80RE-M37 is packaged as a 12-SMD module. This difference affects physical dimensions and pin layout. Circuit board design must accommodate the specific module configuration selected for implementation.

Q: What compliance certifications apply to the Quectel L80RE-M37?

A: The Quectel L80RE-M37 is ROHS3 compliant and REACH unaffected. Both certifications indicate regulatory alignment with current environmental and hazardous substance restrictions.

Q: How do moisture sensitivity levels affect component handling?

A: The Sierra Wireless AirLink 1103872 has MSL 4 (72-hour moisture sensitivity window), while the Quectel L80RE-M37 has MSL 3 (168-hour moisture sensitivity window). Lower MSL ratings provide extended handling time before component exposure to moisture becomes problematic. Storage and assembly procedures must follow the specific MSL requirements of the selected component.

Q: What is the significance of the product status designations?

A: The Sierra Wireless AirLink 1103872 is classified as obsolete, indicating discontinued production and limited availability. The Quectel L80RE-M37 is designated as not for new designs, indicating current availability but potential future discontinuation. For new system development, alternative components with active product status should be evaluated.
