Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2118315-1 is determined by alignment across the following critical parameters:

Frequency Compatibility: Both the main part and substitute must operate at 2.4GHz and 5GHz dual-band frequencies within the UHF and SHF frequency groups to maintain RF performance in WLAN applications.

Termination Method: Solder termination is required for direct PCB integration without additional adapters or interface modifications.

Mounting Configuration: Surface mount technology ensures compatibility with standard PCB assembly processes and footprint requirements.

Physical Dimensions: Maximum height of 0.169" (4.28mm) must be maintained to prevent mechanical interference with enclosures and adjacent components.

Number of Bands: Dual-band operation (2 bands) is essential for simultaneous 2.4GHz and 5GHz WLAN support.

The TE Connectivity 2118788-1 satisfies all substitution criteria through equivalent frequency coverage, solder termination, surface mount configuration, and identical maximum height specification.
