Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94143 is determined by the following critical parameters:

Frequency Compatibility: The MAF94143 operates at 2.5GHz. Substitute parts must support the 2.4GHz to 2.5GHz frequency band to maintain RF performance within the intended application bandwidth.

Connector Termination: The MAF94143 uses U.FL (UMCC) IPEX MHF1 connector. Substitute parts must employ U.FL (UMCC) connector family terminations to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.

Antenna Classification: The MAF94143 is a dipole antenna. Substitute parts may include alternative antenna types (such as whip or straight configurations) provided they operate within the specified frequency range and maintain equivalent radiation characteristics for the application.

Regulatory Compliance: Both the main part and substitutes must maintain MSL 1 rating and appropriate export control classifications (ECCN/HTSUS codes).

Engineering Selection Recommendations

The 0600-00057 serves as an active substitute for the obsolete MAF94143 based on the following engineering criteria:

Frequency Band Alignment: The 0600-00057 operates across the 2.4GHz to 2.5GHz range, encompassing the MAF94143 operating point of 2.5GHz. This frequency overlap ensures RF performance compatibility within the intended application band.

Connector Family Compatibility: Both parts utilize U.FL (UMCC) IPEX connector family terminations. While the MAF94143 specifies IPEX MHF1 and the 0600-00057 specifies IPEX MHF4, both are U.FL (UMCC) standard connectors suitable for PCB-mounted RF applications.

Product Status and Availability: The 0600-00057 maintains Active product status with 671 units in stock, providing supply continuity for the discontinued MAF94143 (1127 units remaining). Active status ensures long-term availability and manufacturing support.

Regulatory Compliance: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental performance. The 0600-00057 carries RoHS Compliant and EAR99 export classification, meeting current regulatory requirements.

Antenna Type Variation: The transition from dipole (MAF94143) to whip/straight configuration (0600-00057) represents a functional design change. The whip antenna provides specified performance metrics (2dBi gain, -10dB return loss, VSWR 2) suitable for 2.4GHz to 2.5GHz ISM band applications.

Frequently Asked Questions (FAQ)

Q: Can the 0600-00057 directly replace the MAF94143 in existing designs?

A: The 0600-00057 is electrically compatible within the 2.4GHz to 2.5GHz frequency band and uses U.FL (UMCC) connector termination. However, the antenna type differs (whip versus dipole), and the connector variant changes from IPEX MHF1 to IPEX MHF4. Physical layout and mating connector compatibility must be verified for your specific PCB design.

Q: What are the key differences in antenna performance between these parts?

A: The 0600-00057 provides documented RF performance specifications (2dBi gain, -10dB return loss, VSWR 2) across the 2.4GHz to 2.5GHz band. The MAF94143 specifications for these parameters are not provided in the technical data. The 0600-00057 whip configuration offers a maximum height of 104mm, which may impact form factor considerations in space-constrained applications.

Q: Are both parts compliant with current environmental and export regulations?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating. The 0600-00057 is RoHS Compliant and carries EAR99 export classification. The MAF94143 carries ECCN 5A991G classification. Verify export compliance requirements for your specific end-use application and destination.

Q: What is the significance of the IPEX MHF1 versus IPEX MHF4 connector difference?

A: Both connectors are U.FL (UMCC) standard family components. The MHF1 and MHF4 designations indicate different mechanical variants within the U.FL standard. Compatibility depends on the mating connector on your PCB. Verify that your existing U.FL receptacle accommodates the MHF4 variant used on the 0600-00057.

Q: Is the 0600-00057 suitable for the same frequency band as the MAF94143?

A: Yes. The 0600-00057 operates across 2.4GHz to 2.5GHz, which includes the MAF94143 operating point of 2.5GHz. Both parts are suitable for 2.4GHz to 2.5GHz ISM band applications.
