Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MAF94146 is based on the following critical parameters:

Connector Compatibility: Both the main part and substitute maintain identical U.FL (UMCC) IPEX MHF1 termination, ensuring mechanical and electrical interface compatibility.

Frequency Band Alignment: The MAF94146 operates in the 802.11b/g band (2.4GHz ISM band). The substitute part FXP70.07.0053A operates at 2.4GHz with a frequency range of 2.4GHz to 2.483.5GHz, covering the same regulatory band.

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

Connector Standard: The IPEX MHF1 connector is the determining factor for physical interchangeability in embedded applications.

Parameter Comparison

Engineering Selection Recommendations

The FXP70.07.0053A from Taoglas Limited is a functionally equivalent substitute for the obsolete MAF94146. Selection is based on the following engineering criteria:

Connector Compatibility: Identical U.FL (UMCC) IPEX MHF1 termination ensures direct mechanical and electrical interface compatibility without PCB redesign.

Frequency Band Coverage: The substitute operates within the 2.4GHz ISM band (2.4GHz to 2.483.5GHz), fully encompassing the 802.11b/g frequency range of the original part.

Environmental Classification: Both parts maintain MSL 1 (Unlimited) rating, indicating equivalent moisture sensitivity and storage requirements.

Regulatory Compliance: The substitute is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The original part's ECCN classification (5A991G) differs from the substitute's EAR99 classification, which may affect export considerations depending on destination.

Product Status: The substitute is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete original part.
