Engineering Selection Recommendations

Primary Substitute: ANT-2.4-PML-UFL is the designated equivalent for MAF94466 replacement applications.

Justification: The ANT-2.4-PML-UFL maintains active manufacturing status through TE Connectivity Linx, ensuring long-term supply chain viability. Frequency range coverage (2.35-2.6 GHz) fully encompasses the original 2400-2500 MHz specification. U.FL connector compatibility eliminates interface redesign requirements. Both parts maintain identical RoHS compliance and MSL 1 ratings, satisfying regulatory and environmental requirements without modification.

Compliance Continuity: The substitute carries EAR99 ECCN classification (compared to 5A991G for the original), which may affect export documentation requirements depending on destination jurisdiction. REACH status confirmation as "REACH Unaffected" provides additional regulatory assurance.

Supply Chain Status: With 3488 units in stock versus 755 units of the obsolete MAF94466, the substitute provides superior availability for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can ANT-2.4-PML-UFL directly replace MAF94466 without PCB modifications?

A: Yes. Both parts use identical U.FL (UMCC) connector termination. No footprint or interface changes are required. Physical mounting may differ due to the panel mount configuration of the substitute; verify mechanical clearance in your application.

Q: What is the frequency overlap between these two antennas?

A: The MAF94466 operates at 2400-2500 MHz (2.4-2.5 GHz). The ANT-2.4-PML-UFL covers 2350-2600 MHz (2.35-2.6 GHz). The overlap region is 2400-2500 MHz, ensuring full functional compatibility within the original operating band.

Q: Are there differences in antenna gain or radiation pattern?

A: The ANT-2.4-PML-UFL specifies 2.4 dBi gain and 1.9 VSWR. The MAF94466 does not provide published gain or VSWR specifications. If your application requires specific gain characteristics, measure the MAF94466 performance in your system before substitution to establish baseline requirements.

Q: Do both parts meet the same environmental standards?

A: Yes. Both MAF94466 and ANT-2.4-PML-UFL are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating. Environmental handling and storage requirements are identical.

Q: What is the cable length difference?

A: The ANT-2.4-PML-UFL includes a 305 mm (12-inch) cable assembly. The MAF94466 description specifies "12" U.FL," indicating similar cable length. Confirm exact cable routing requirements in your mechanical design.

Q: Are there export control implications when switching to ANT-2.4-PML-UFL?

A: The ANT-2.4-PML-UFL carries EAR99 classification, while the MAF94466 is classified as 5A991G. Verify export requirements with your compliance department, as destination country restrictions may differ between classifications.

Q: Can ANT-2.4-PML-UFL be used in Bluetooth, Wi-Fi, and Zigbee™ applications?

A: Yes. The ANT-2.4-PML-UFL is explicitly rated for Bluetooth, Thread, Wi-Fi, and Zigbee™ protocols operating in the 2.4 GHz ISM band, matching the intended application space of the MAF94466.
