Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the N548M8CB-REEL is determined by strict alignment of the following critical parameters:

• RF Protocol and Frequency: Bluetooth v4.1 at 2.4GHz
• Integrated IC: nRF51422
• Memory Configuration: 256kB Flash, 16kB RAM
• Serial Communication Interfaces: I2C, SPI, UART
• Antenna Configuration: Integrated trace antenna
• Voltage Supply Range: 1.8V ~ 3.6V
• Package Type: 35-SMD Module
• Mounting Technology: Surface Mount

The N550M8CC-REEL meets all substitution criteria as it maintains identical RF specifications, IC integration, memory capacity, interface protocols, antenna design, voltage requirements, and package configuration. The primary distinction is product status and packaging format.
