Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94243 is determined by the following criteria based on provided parameters:

Primary Substitution Criteria:

• Manufacturer alignment: TE Connectivity Laird NanoBlue series
• RF Family compatibility: 802.11b/g wireless standards (2.4GHz band)
• Termination type: IPEX or equivalent RF connector interface
• Moisture sensitivity: MSL 1 classification
• Export compliance: ECCN 5A991G classification

The MAF94102 qualifies as a substitute part based on shared manufacturer origin (TE Connectivity Laird), identical NanoBlue series designation, overlapping frequency band operation (2.4GHz), matching MSL rating, and identical ECCN classification. Both components are designed for wireless connectivity applications within the 2.4GHz spectrum.

Parameter Comparison

Engineering Selection Recommendations

MAF94243 (Primary Part): The MAF94243 remains available in inventory (1145 units) despite obsolete status classification. This part maintains full compliance with ECCN 5A991G export regulations and carries MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling. Selection of the original part number is appropriate when inventory availability permits and design specifications align with embedded 802.11b/g antenna requirements.

MAF94102 (Active Substitute): The MAF94102 is classified as an active product with confirmed inventory (881 units), providing long-term procurement viability. This substitute shares identical manufacturer origin, series designation, MSL rating, and ECCN classification with the MAF94243. The MAF94102 operates within the 2.4GHz ~ 2.5GHz frequency range, supporting both Bluetooth and Wi-Fi standards. RoHS compliance certification is documented for the MAF94102, meeting environmental regulatory requirements. The active product status ensures continued availability for future procurement cycles.

Compliance Alignment: Both parts carry identical ECCN 5A991G classification, confirming equivalent export control treatment. MSL 1 rating on both components eliminates moisture-related handling restrictions. Selection between these parts should prioritize the active product (MAF94102) for new designs and long-term production planning, while the MAF94243 remains suitable for legacy system support where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Why is the MAF94243 classified as obsolete when inventory is available?

A: Obsolete classification indicates the manufacturer has discontinued active production and support for this part number. Remaining inventory represents existing stock. The MAF94102 provides an active alternative with equivalent functional characteristics and compliance certifications.

Q: Are the MAF94243 and MAF94102 electrically interchangeable?

A: Both parts are manufactured by TE Connectivity Laird within the NanoBlue series and operate within the 2.4GHz wireless band. Substitution is supported by shared manufacturer origin, identical MSL rating, and matching ECCN classification. Physical form factor and termination type differences (IPEX vs. Flying Lead) require mechanical design verification during integration.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both the MAF94243 and MAF94102 can be stored and handled without desiccant packaging or humidity-controlled environments, simplifying logistics and inventory management.

Q: Does the MAF94102 support 802.11b/g applications like the MAF94243?

A: The MAF94102 is specified for Bluetooth and Wi-Fi applications within the 2.4GHz frequency band. The 2.4GHz ~ 2.5GHz frequency range encompasses 802.11b/g spectrum. Frequency band overlap supports functional substitution for wireless connectivity applications.

Q: What export control considerations apply to these parts?

A: Both the MAF94243 and MAF94102 carry ECCN 5A991G classification, indicating identical export control treatment under U.S. regulations. No differential compliance burden exists between the two part numbers.

Q: Should new designs use the MAF94243 or MAF94102?

A: New designs should specify the MAF94102 due to active product status, ensuring long-term procurement availability and manufacturer support. The MAF94243 is appropriate only for legacy system maintenance where existing inventory is available and design constraints require the original part number.
