Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94140 is based on the following critical parameters:

Frequency Compatibility: The MAF94140 operates at 2.5GHz within the 802.11BG band. The identified substitute part 0600-00057 operates across the 2.4GHz to 2.5GHz frequency range, providing direct overlap with the original part's operating band.

Antenna Classification: Both the main part and substitute are RF antennas from TE Connectivity Laird, ensuring manufacturer consistency and design philosophy alignment.

Electrical Performance Metrics: The substitute part provides defined electrical parameters (VSWR, Return Loss, Gain) that establish measurable performance characteristics for system integration.

Regulatory Compliance: Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent environmental handling requirements.

Connector and Mounting Compatibility: The substitute part specifies U.FL (UMCC) IPEX MHF4 connector termination and connector mount configuration, providing defined mechanical integration points.
