MAF94389 RF Antenna Equivalent & Substitute Parts

Part Overview

The MAF94389 is an RF antenna manufactured by TE Connectivity Laird, designated as a dipole antenna with SMA connector termination. This component is classified as obsolete, indicating discontinuation from the manufacturer. The product carries an MSL rating of 1 (Unlimited moisture sensitivity), indicating no moisture-related storage restrictions. Due to its obsolete status, identification of functionally equivalent substitute components is necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAF94389 is based on the following critical parameters:

Connector Compatibility: The MAF94389 features SMA termination. Substitute components must maintain SMA Male connector compatibility to ensure direct integration into existing RF circuits without adapter requirements.

Electrical Characteristics: While specific frequency range, VSWR, return loss, and gain specifications are not provided for the MAF94389, substitute parts must operate within standard RF antenna performance parameters applicable to their designated frequency bands.

Regulatory Compliance: The MAF94389 carries ECCN classification 5A991G. Substitute parts must comply with equivalent or less restrictive export control classifications to maintain regulatory compliance in the same jurisdictions.

Moisture Sensitivity: Both the main part and substitute must maintain MSL 1 (Unlimited) classification to ensure compatibility with standard storage and handling procedures.

Packaging and Inventory: The MAF94389 is supplied in standard packaging with 1011 units currently available. Substitute parts should be available in comparable quantities to support production requirements.

The identified substitute ANT-2WHIP9-SMA meets these core substitution criteria through SMA Male connector termination, active product status, and MSL 1 classification.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The MAF94389 is classified as obsolete. The ANT-2WHIP9-SMA is an active product with confirmed current inventory (931 units), ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The ANT-2WHIP9-SMA carries ECCN classification EAR99, which is less restrictive than the MAF94389's 5A991G classification. This provides equivalent or improved export control flexibility for international applications.

Connector Compatibility: Both components feature SMA termination, enabling direct mechanical and electrical compatibility without connector adapters or redesign.

Moisture Handling: Both parts maintain MSL 1 (Unlimited) classification, confirming compatibility with standard component storage, handling, and assembly processes without special moisture control requirements.

Frequency Band Consideration: The ANT-2WHIP9-SMA operates in the 2.4GHz ~ 2.5GHz band (WiFi/WLAN applications). Selection of this substitute requires confirmation that the MAF94389 application operates within or overlaps this frequency range. If the original application requires different frequency bands, alternative substitutes outside the provided data set may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the ANT-2WHIP9-SMA directly replace the MAF94389 without circuit modifications?

A: Direct mechanical and electrical replacement is possible due to identical SMA connector termination. However, frequency band compatibility must be verified. The ANT-2WHIP9-SMA operates at 2.4GHz ~ 2.5GHz. If the MAF94389 application requires different frequency bands, circuit performance may be affected.

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

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions. Both components can be stored and handled using standard industrial practices without specialized moisture-controlled environments or baking procedures prior to assembly.

Q: Why does the ANT-2WHIP9-SMA have a less restrictive ECCN classification?

A: ECCN EAR99 is a general classification for items not subject to specific export control restrictions, while 5A991G is a controlled classification. The ANT-2WHIP9-SMA's EAR99 status may simplify export documentation and international distribution compared to the original part.

Q: Are there physical form factor differences between these antennas?

A: Yes. The MAF94389 is a dipole antenna with unspecified dimensions. The ANT-2WHIP9-SMA is a whip-type antenna with tilt capability and a maximum height of 14.961" (380.00mm). Physical space constraints in the application must be evaluated before substitution.

Q: What is the antenna gain difference, and does it matter?

A: The ANT-2WHIP9-SMA provides 9dBi gain. The MAF94389 gain specification is not provided in available documentation. Gain differences affect signal strength and coverage patterns. Applications requiring specific gain characteristics must confirm compatibility with the 9dBi specification.

Q: Is the ANT-2WHIP9-SMA suitable for all applications using the MAF94389?

A: Substitution is mechanically and electrically compatible through SMA termination. However, frequency band, gain, antenna type (dipole vs. whip), and physical form factor differences require application-specific validation before implementation.
