Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the MAF94259 is based on the following critical parameters:

Frequency Compatibility: Both the main part and substitute must operate within overlapping frequency bands. The MAF94259 operates at 2.4GHz ~ 2.5GHz. Substitute components must support the 2.4GHz center frequency band.

Frequency Group Classification: Both components must fall within the UHF (2GHz ~ 3GHz) frequency group to ensure RF performance characteristics remain within acceptable operating ranges.

Number of Bands: Single-band operation is required for direct substitution. Multi-band antennas introduce additional design complexity and are not considered equivalent.

Regulatory Compliance: Both components share identical ECCN (5A991G) and HTSUS (8529.10.9100) classifications, confirming regulatory equivalence.

Moisture Sensitivity Level: Both components maintain MSL 1 (Unlimited) rating, ensuring identical handling and storage requirements.

The MAF94414 meets these substitution criteria through matching frequency group classification, overlapping operational frequency range (2.4GHz ~ 2.484GHz), single-band configuration, and identical regulatory classifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAF94259 is classified as Obsolete, while the MAF94414 maintains Active product status. Active status ensures continued manufacturer support, availability, and compliance with current regulatory requirements.

Regulatory Compliance: Both components share identical ECCN and HTSUS classifications, confirming equivalent export control and tariff treatment. The MAF94414 carries RoHS Compliant certification, meeting current environmental compliance standards.

Frequency Band Alignment: The MAF94414 operates within the 2.4GHz ~ 2.484GHz range, which overlaps with the MAF94259 operational band of 2.4GHz ~ 2.5GHz. Both components are classified within the UHF (2GHz ~ 3GHz) frequency group.

Design Integration Differences: The MAF94259 utilizes connector-based mounting with RP-SMA male termination, while the MAF94414 employs surface mount technology with solder termination. These differences require PCB layout and assembly process modifications. The MAF94414 provides significantly reduced form factor (4.00mm vs. 80.00mm height).

Supply Chain Availability: Current inventory status indicates 1046 units of MAF94414 available as new original stock, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the MAF94414 directly replace the MAF94259 without design modifications?

A: No. While both components operate within compatible frequency bands and share regulatory classifications, they differ in mounting technology (connector mount vs. surface mount), termination type (RP-SMA male vs. solder), and form factor (80mm vs. 4mm height). PCB layout and assembly process changes are required.

Q: What frequency bands do these antennas support?

A: The MAF94259 operates at 2.4GHz ~ 2.5GHz. The MAF94414 operates at 2.4GHz ~ 2.484GHz. Both support single-band operation within the UHF frequency group (2GHz ~ 3GHz). The frequency ranges overlap at 2.4GHz ~ 2.484GHz.

Q: Are there differences in gain specifications between these components?

A: The MAF94259 specifies 1dBi gain. The MAF94414 does not provide a gain specification in the available technical data. Gain performance differences may exist due to antenna type differences (whip vs. chip configuration).

Q: What is the significance of the VSWR specification on the MAF94414?

A: The MAF94414 specifies VSWR of 2.3. The MAF94259 does not provide VSWR data. VSWR (Voltage Standing Wave Ratio) indicates impedance matching efficiency. A VSWR of 2.3 is within acceptable ranges for 2.4GHz antenna applications.

Q: Do both components have identical moisture sensitivity requirements?

A: Yes. Both the MAF94259 and MAF94414 carry MSL 1 (Unlimited) ratings, indicating identical moisture sensitivity levels and equivalent handling, storage, and reflow requirements.

Q: What are the packaging differences?

A: The MAF94259 packaging is listed as dash (not specified). The MAF94414 is supplied in Bulk packaging. Confirm packaging requirements with procurement specifications.

Q: Are both components RoHS compliant?

A: The MAF94414 is explicitly marked as RoHS Compliant. RoHS compliance status for the MAF94259 is not specified in the available data.
