Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94411 is determined by the following critical parameters:

Primary Substitution Criteria:

• RF Family/Standard: WiFi compatibility required
• Frequency Range: Must cover or encompass 2.4GHz ~ 2.484GHz band
• Termination Type: U.FL or equivalent connector compatibility
• Mounting compatibility: Surface mount or adhesive mount acceptable for embedded applications
• Electrical performance: VSWR and impedance matching within acceptable tolerance for 2.4GHz operation

Secondary Considerations:

• Product Status: Active status preferred for long-term availability
• Moisture Sensitivity Level: MSL 1 maintains handling compatibility
• Compliance certifications: RoHS and REACH status for regulatory alignment

The FXP810.07.0100C qualifies as a substitute based on its dual-band WiFi capability that includes full coverage of the 2.4GHz ~ 2.5GHz band, active product status, and compatible termination options.

Parameter Comparison

Engineering Selection Recommendations

For MAF94411 Replacement:

The FXP810.07.0100C serves as a functional substitute for the obsolete MAF94411 in 2.4GHz WiFi applications. The substitute provides superior electrical performance with a VSWR of 1.7 compared to the original 2.3, ensuring improved impedance matching across the 2.4GHz band. Both parts maintain MSL 1 classification, eliminating moisture sensitivity concerns during handling and storage.

Compliance Advantages:

The FXP810.07.0100C carries active product status with documented RoHS3 compliance and REACH unaffected designation, supporting regulatory requirements for new designs and long-term component availability. The MAF94411's obsolete status necessitates transition planning for production continuity.

Physical Integration Considerations:

The substitute employs adhesive mounting with significantly reduced height (0.004" versus 0.157"), requiring PCB layout modification. The FXP810.07.0100C includes a 100mm cable with U.FL (UMCC) and IPEX MHF1 termination options, providing flexible integration pathways compared to the original solder termination.

Dual-Band Capability:

The FXP810.07.0100C extends functionality to 5.4GHz operation (4.9GHz ~ 5.8GHz), enabling 802.11a/n/ac support beyond the original single-band 2.4GHz limitation. This enhancement supports future-proofing for systems requiring multi-band WiFi capability.

Frequently Asked Questions (FAQ)

Q: Can the FXP810.07.0100C directly replace the MAF94411 without PCB modifications?

A: No. The FXP810.07.0100C uses adhesive mounting with a 100mm cable and U.FL/IPEX MHF1 termination, whereas the MAF94411 employs solder surface mount termination. PCB layout changes are required to accommodate the different mounting method and connector type.

Q: What is the primary reason for substitution?

A: The MAF94411 is obsolete. The FXP810.07.0100C is an active product with documented availability, making it suitable for new designs, production continuity, and component replenishment.

Q: Does the FXP810.07.0100C cover the full 2.4GHz frequency range of the MAF94411?

A: Yes. The FXP810.07.0100C operates across 2.4GHz ~ 2.5GHz, which fully encompasses the MAF94411's 2.4GHz ~ 2.484GHz band. The substitute also adds 5.4GHz band capability.

Q: What is the significance of the VSWR difference between the two parts?

A: The FXP810.07.0100C has a VSWR of 1.7 compared to the MAF94411's 2.3. Lower VSWR indicates better impedance matching and improved RF efficiency at 2.4GHz, resulting in superior antenna performance.

Q: Are both parts compatible with MSL 1 handling procedures?

A: Yes. Both the MAF94411 and FXP810.07.0100C carry MSL 1 (Unlimited) classification, requiring no special moisture control during storage, handling, or assembly.

Q: What connector types does the FXP810.07.0100C support?

A: The FXP810.07.0100C provides U.FL (UMCC) and IPEX MHF1 termination options via a 100mm cable, offering flexibility for different PCB connector configurations.

Q: Is the FXP810.07.0100C compliant with current regulatory standards?

A: Yes. The FXP810.07.0100C is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for component procurement and product certification.
