Key Parameters

Substitute Part Grouping Explanation

The WGM160PX22KGA3R qualifies as a functional substitute based on the following alignment of critical parameters:

Common RF Specifications:

• WiFi 802.11b/g/n protocol compliance
• 2.4GHz frequency band operation (2.412GHz ~ 2.484GHz covers the 2.4GHz requirement)
• 16dBm power output (identical)
• Enhanced sensitivity at -95.5dBm (improvement over -94dBm)
• Surface mount technology

Supply Voltage Compatibility:

• WGM160PX22KGA3R operates at 3V ~ 3.6V, which encompasses the 3.3V requirement of the AMW006-3.3.2R

Serial Interface Capability:

• WGM160PX22KGA3R includes SPI and UART interfaces, matching the minimum interface requirements of the original part

Environmental Specifications:

• Operating temperature range of -40°C ~ 85°C exceeds the original -30°C ~ 85°C specification
• MSL rating of 3 (168 Hours) is identical

Substitution is constrained by differences in current consumption, memory configuration, and antenna integration approach, which must be evaluated within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The WGM160PX22KGA3R serves as a functional equivalent for the discontinued AMW006-3.3.2R in applications where the following conditions are met:

Electrical Compatibility: The substitute operates within the 3V ~ 3.6V supply range, accommodating the original 3.3V specification. However, power consumption increases substantially: receiving current rises from 5.7mA to 34.5mA ~ 38.5mA, and transmitting current increases from 11.4mA to 131.4mA ~ 141.3mA. Power supply design and thermal management must be re-evaluated accordingly.

Interface Compatibility: Both parts support SPI and UART serial interfaces. The WGM160PX22KGA3R provides additional interface options (Ethernet, I2C, USART, USB) that may be leveraged or remain unused depending on application architecture.

Physical Integration: The original AMW006-3.3.2R uses castellation mounting with external antenna connection. The WGM160PX22KGA3R employs a 55-SMD module package with integrated antenna. PCB layout and antenna design modifications are required for substitution.

Regulatory and Compliance: Both parts carry identical ECCN (5A992C) and HTSUS (8517.62.0090) classifications. The WGM160PX22KGA3R is certified ROHS3 compliant, whereas the original part's RoHS status is not specified. Both maintain MSL rating 3 (168 Hours).

Product Status Consideration: Both parts are legacy products. The AMW006-3.3.2R is discontinued; the WGM160PX22KGA3R is marked "Not For New Designs." For new development, evaluation of current-generation WiFi transceiver modules from Silicon Labs is recommended to ensure long-term supply availability and access to current firmware support.

Frequently Asked Questions (FAQ)

Q: Can the WGM160PX22KGA3R directly replace the AMW006-3.3.2R without PCB modifications?

A: No. The WGM160PX22KGA3R uses a different package form (55-SMD module versus castellation) and integrates the antenna internally, whereas the AMW006-3.3.2R requires external antenna connection. PCB layout redesign is necessary.

Q: What is the primary limitation when substituting these parts?

A: Current consumption increases significantly. The WGM160PX22KGA3R draws 34.5mA ~ 38.5mA during reception and 131.4mA ~ 141.3mA during transmission, compared to 5.7mA and 11.4mA respectively for the original part. Power supply capacity and thermal design must be re-evaluated.

Q: Are the serial interfaces compatible?

A: Yes, for the minimum required interfaces. Both parts support SPI and UART. The WGM160PX22KGA3R provides additional interfaces (Ethernet, I2C, USART, USB) that are not present in the original part but do not create incompatibility.

Q: What is the frequency band coverage difference?

A: The AMW006-3.3.2R operates at 2.4GHz. The WGM160PX22KGA3R operates across 2.412GHz ~ 2.484GHz, which fully covers the 2.4GHz ISM band and provides broader frequency flexibility.

Q: Are both parts suitable for new designs?

A: No. Both parts carry legacy product status. The AMW006-3.3.2R is discontinued; the WGM160PX22KGA3R is marked "Not For New Designs." Current-generation WiFi transceiver modules should be evaluated for new development to ensure supply continuity and access to current firmware and support resources.

Q: How do the antenna configurations differ?

A: The AMW006-3.3.2R uses castellation mounting with no integrated antenna, requiring external antenna design and connection. The WGM160PX22KGA3R integrates the antenna within the chip module, eliminating external antenna requirements but requiring different PCB layout considerations.

Q: Is the supply voltage range compatible?

A: Yes. The original part requires 3.3V. The WGM160PX22KGA3R operates at 3V ~ 3.6V, which encompasses 3.3V within its specified range.
