Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94142 is based on the following critical parameters that define functional equivalence:

Frequency Compatibility: The original part operates at 2.4GHz to 2.5GHz for 802.11b/g applications. Substitute parts must operate within or encompass this frequency range to maintain RF performance in the intended application.

Antenna Classification: The MAF94142 is a dipole antenna. Substitute parts may employ alternative antenna types (such as whip or tilt configurations) provided they deliver equivalent RF performance characteristics within the specified frequency band.

Moisture Sensitivity Level: Both the original and substitute parts maintain MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Regulatory Compliance: The original part carries ECCN 5A991G classification. Substitute parts with ECCN EAR99 or equivalent classifications are acceptable for export and distribution purposes.

The identified substitute part RFDPA870910NNAB3G1 satisfies these substitution criteria through frequency band alignment (2.4GHz to 2.5GHz), active product status, and compatible regulatory classifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAF94142 is classified as obsolete, making RFDPA870910NNAB3G1 the appropriate selection for new designs and ongoing system support. The substitute part maintains active product status with established supply chain availability.

Frequency Band Alignment: Both parts operate within the 2.4GHz to 2.5GHz frequency range, ensuring compatibility with 802.11b/g wireless standards and applications requiring operation in this spectrum.

Regulatory and Compliance Alignment: The substitute part RFDPA870910NNAB3G1 carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The ECCN EAR99 classification provides equivalent export control treatment compared to the original part's 5A991G designation.

Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) classification, indicating no additional moisture management requirements during component handling, storage, or assembly.

Mechanical Integration: The substitute part specifies connector mount configuration with defined height parameters (87.00mm maximum), enabling precise mechanical integration planning for system redesign or retrofit applications.

Frequently Asked Questions (FAQ)

Q: Can RFDPA870910NNAB3G1 directly replace MAF94142 in existing designs?

A: RFDPA870910NNAB3G1 operates within the same 2.4GHz to 2.5GHz frequency band as MAF94142. However, the antenna type differs (whip/tilt versus dipole) and mechanical mounting specifications vary. Physical integration assessment is required to confirm mechanical compatibility with existing PCB layouts and enclosure designs.

Q: What are the key electrical parameters that define substitution eligibility?

A: Frequency range alignment (2.4GHz to 2.5GHz) is the primary electrical criterion. The substitute part provides specified VSWR (2), return loss (-10dB), and gain (2dBi) characteristics. These parameters must be evaluated against original system performance requirements to confirm functional equivalence.

Q: Are there moisture sensitivity or storage requirement differences?

A: Both MAF94142 and RFDPA870910NNAB3G1 maintain MSL 1 (Unlimited) classification. No differential moisture sensitivity constraints exist between the original and substitute parts.

Q: What packaging and supply considerations apply to RFDPA870910NNAB3G1?

A: RFDPA870910NNAB3G1 is supplied in bulk packaging with 649 pieces currently in stock. The part carries active product status, ensuring ongoing availability for production and support applications.

Q: How do regulatory classifications affect component selection?

A: Both parts carry acceptable export control classifications (original: 5A991G; substitute: EAR99). The substitute part additionally meets ROHS3 compliance and REACH unaffected status, aligning with current environmental regulations and supply chain requirements.
