Substitute Part Grouping Explanation

The WGM160PX22KGA3R qualifies as a functional equivalent based on the following core substitution criteria:

Common RF Characteristics:

• Identical manufacturer (Silicon Labs)
• Same RF family and protocol (WiFi 802.11b/g/n)
• Overlapping frequency band (2.4GHz range: 2.412GHz ~ 2.484GHz encompasses the 2.4GHz specification)
• Identical power output (16dBm)
• Enhanced sensitivity (-95.5dBm vs -94dBm)
• Higher data rate capability (72.2Mbps vs 54Mbps)

Compatible Electrical Specifications:

• Supply voltage range (3V ~ 3.6V) encompasses the 3.3V requirement
• Surface mount mounting type
• Extended operating temperature range (-40°C ~ 85°C)
• Identical MSL rating (3, 168 Hours)
• Identical ECCN and HTSUS classifications

Interface Compatibility:

• Includes all serial interfaces of the main part (SPI, UART) plus additional options (Ethernet, I2C, USB, USART)

Parameter Comparison

Engineering Selection Recommendations

The WGM160PX22KGA3R serves as a direct functional substitute for the discontinued AMW006-3.2.0R based on RF performance alignment and interface compatibility. Both components share identical manufacturer origin, protocol support, and power output specifications.

Key Considerations for Selection:

The substitute part demonstrates superior RF performance with improved sensitivity (-95.5dBm vs -94dBm) and higher data rate capability (72.2Mbps vs 54Mbps). Supply voltage compatibility is maintained within the substitute's 3V ~ 3.6V operating range.

Critical Design Differences:

The WGM160PX22KGA3R features an integrated antenna configuration compared to the castellation antenna-not-included design of the AMW006-3.2.0R. This represents a fundamental architectural difference requiring PCB layout and antenna design modifications.

Current consumption differs significantly. The substitute draws 34.5mA ~ 38.5mA in receive mode and 131.4mA ~ 141.3mA in transmit mode, compared to 5.7mA and 11.4mA respectively for the main part. Power supply and thermal management designs must accommodate these increased current requirements.

The substitute provides expanded memory (2MB Flash, 512kB RAM vs 1MB Flash) and additional serial interface options (Ethernet, I2C, USB, USART). The 55-SMD Module package differs from the original Module package, requiring PCB footprint verification.

The WGM160PX22KGA3R carries ROHS3 compliance certification, meeting current environmental standards. Both components maintain identical MSL ratings and ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the WGM160PX22KGA3R directly replace the AMW006-3.2.0R without design modifications?

A: No. While RF performance and interface compatibility are maintained, the antenna configuration difference (integrated vs castellation) and significantly higher current consumption require PCB layout and power supply redesign. The different package form factor (55-SMD Module vs Module) necessitates footprint verification.

Q: What are the primary electrical differences between these parts?

A: The substitute draws substantially higher current in both receive (34.5mA ~ 38.5mA vs 5.7mA) and transmit (131.4mA ~ 141.3mA vs 11.4mA) modes. Supply voltage compatibility is maintained as the substitute's 3V ~ 3.6V range encompasses the 3.3V requirement. The substitute provides additional memory capacity and expanded serial interface options.

Q: Are the frequency specifications compatible?

A: Yes. The substitute's frequency range (2.412GHz ~ 2.484GHz) covers the main part's 2.4GHz specification. Both components support identical 802.11b/g/n protocols.

Q: What packaging differences exist between these modules?

A: The AMW006-3.2.0R uses castellation surface mount packaging without integrated antenna. The WGM160PX22KGA3R is a 55-SMD Module with integrated antenna. These represent different form factors requiring separate PCB design considerations.

Q: Does the substitute meet current compliance requirements?

A: The WGM160PX22KGA3R carries ROHS3 compliance certification. Both components share identical MSL ratings (3, 168 Hours) and ECCN/HTSUS classifications, maintaining regulatory alignment.

Q: What is the impact of the integrated antenna on system design?

A: The integrated antenna eliminates the need for external antenna design but may affect PCB layout flexibility and RF performance characteristics compared to castellation-based antenna implementations. System-level RF testing is required to validate performance in the target application environment.
