Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC-WMX-K77C-TE-1 is determined by the following critical parameters:

• RF Family/Standard and Protocol compatibility (WiFi 802.11a/b/g/n minimum requirement)
• Frequency band coverage (2.4GHz ~ 2.48GHz and 4.9GHz ~ 5.8GHz)
• Data rate capability (150Mbps)
• Power output specification (2dBm)
• Memory configuration (4GB Flash, 1GB DRAM)
• Operating temperature range (-40°C ~ 85°C)
• RoHS compliance and MSL rating
• Base product number alignment (CC-WMX series)

The CC-WMX-K77C-TE qualifies as a direct substitute within the ConnectCore® 6 series, maintaining identical RF performance parameters, memory specifications, and environmental ratings while adding Bluetooth v4.0 capability and utilizing card edge mounting instead of surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

The CC-WMX-K77C-TE is the qualified substitute for the discontinued CC-WMX-K77C-TE-1. Both parts maintain identical RF performance specifications, memory capacity, and environmental operating ranges. The substitute part is currently in active production status, ensuring supply chain availability.

The primary design consideration is the mounting interface difference: the main part uses surface mount packaging while the substitute employs card edge mounting. This distinction requires PCB layout and connector redesign but does not affect RF performance, data rate, frequency coverage, or thermal characteristics.

Both parts maintain RoHS compliance and MSL Level 1 rating, supporting equivalent reliability and environmental standards for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can CC-WMX-K77C-TE replace CC-WMX-K77C-TE-1 in existing designs?

A: RF performance and electrical specifications are identical. Substitution requires PCB redesign to accommodate card edge mounting instead of surface mount packaging. Connector and mechanical integration must be re-evaluated.

Q: What is the primary difference between these parts?

A: The CC-WMX-K77C-TE adds Bluetooth v4.0 protocol support and uses card edge mounting. All WiFi 802.11a/b/g/n parameters, frequency bands, data rates, power output, and memory specifications remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both CC-WMX-K77C-TE-1 and CC-WMX-K77C-TE are RoHS compliant with MSL Level 1 rating.

Q: Why is the main part discontinued?

A: The CC-WMX-K77C-TE-1 is discontinued at DiGi Electronics. The CC-WMX-K77C-TE remains in active production as the current ConnectCore® 6 series offering.

Q: Do both parts support the same frequency bands?

A: Yes. Both parts operate across 2.4GHz ~ 2.48GHz and 4.9GHz ~ 5.8GHz with 150Mbps data rate and 2dBm output power.

Q: What serial interfaces are supported?

A: The main part CC-WMX-K77C-TE-1 supports I2C, SPI, UART, and USB. Serial interface specifications for the substitute part were not provided in the technical data.
