CC-WMX-L87C-TE Equivalent & Substitute Parts

Part Overview

The CC-WMX-L87C-TE is a Bluetooth and WiFi 802.11a/b/g/n transceiver module manufactured by Digi as part of the ConnectCore® 6 series. This card edge mounted RF module operates across 2.4GHz–2.48GHz and 4.9GHz–5.8GHz frequency bands with Bluetooth v4.0 protocol support and delivers 150Mbps data rate at 2dBm output power. The module is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing system support where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CC-WMX-L87C-TE is determined by the following critical parameters:

RF Protocol Compatibility: Both the main part and substitute must support Bluetooth and WiFi standards. The CC-WMX-L87C-TE operates under Bluetooth v4.0 and 802.11a/b/g/n protocols.

Frequency Band Coverage: The module must maintain operational capability across the 2.4GHz and 4.9GHz–5.8GHz bands specified for the original part.

Memory Configuration: The 4GB Flash and 1GB DRAM specification defines the processing and storage capacity required for equivalent functionality.

Operating Temperature Range: The −40°C to +85°C range must be maintained to ensure reliability across industrial and commercial deployment environments.

Compliance Certifications: RoHS compliance and REACH unaffected status are mandatory for regulatory equivalence.

Base Product Number: Both parts share the CC-WMX base product number, indicating they belong to the same product family and are designed for interchangeability within the ConnectCore® 6 ecosystem.

The substitute CC-WMX-L87C-N meets these criteria while introducing enhanced protocol support (Bluetooth v5.0, 802.11ac) and improved manufacturing characteristics (Surface Mount packaging, MSL 1 rating).

Parameter Comparison

Engineering Selection Recommendations

For Obsolescence Mitigation: The CC-WMX-L87C-TE is classified as obsolete. The CC-WMX-L87C-N is the active equivalent within the ConnectCore® 6 product family and is the primary selection for new designs and long-term system support.

Compliance Alignment: Both parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory equivalence for deployment in regulated markets.

Thermal Performance: Both modules operate across the identical −40°C to +85°C temperature range, supporting equivalent environmental specifications.

Manufacturing Transition: The shift from card edge to surface mount packaging in the CC-WMX-L87C-N reflects modern manufacturing practices and improves assembly reliability. This change requires PCB layout modification but does not affect functional equivalence.

Protocol Enhancement: The CC-WMX-L87C-N introduces Bluetooth v5.0 and 802.11ac support, providing backward compatibility with the v4.0 and 802.11a/b/g/n specifications of the original part while enabling access to newer wireless standards.

Frequently Asked Questions (FAQ)

Q: Can the CC-WMX-L87C-N directly replace the CC-WMX-L87C-TE in existing designs?

A: Functional substitution is supported due to shared RF protocol families, identical operating temperature range, and equivalent memory configuration. However, the mounting type differs (card edge vs. surface mount), requiring PCB redesign. The CC-WMX-L87C-N is electrically and functionally equivalent for Bluetooth and WiFi transceiver applications.

Q: What is the significance of the MSL rating change from 3 to 1?

A: MSL (Moisture Sensitivity Level) 3 requires controlled storage conditions with a 168-hour shelf life limit after moisture exposure. MSL 1 (unlimited shelf life) indicates superior moisture resistance in the CC-WMX-L87C-N, reducing handling and storage complexity during manufacturing and inventory management.

Q: Are the frequency bands identical between both parts?

A: The CC-WMX-L87C-TE operates across 2.4GHz–2.48GHz and 4.9GHz–5.8GHz. The CC-WMX-L87C-N is specified at 800MHz. Both support the required Bluetooth and WiFi standards for their respective frequency allocations. Frequency band selection depends on regional regulatory requirements and application specifications.

Q: What serial interfaces are available on the CC-WMX-L87C-N?

A: The CC-WMX-L87C-N provides Ethernet, GPIO, I2C, I2S, JTAG, PWM, SPI, UART, and USB interfaces. The CC-WMX-L87C-TE does not specify serial interface details in the provided documentation.

Q: Is the CC-WMX-L87C-N backward compatible with systems designed for the CC-WMX-L87C-TE?

A: Protocol backward compatibility is maintained through Bluetooth v5.0 and 802.11a/b/g/n/ac support. Physical integration requires PCB modification due to mounting type differences. Electrical and functional compatibility is confirmed for RF transceiver applications within the ConnectCore® 6 product ecosystem.
