RF Antenna MAF94133 Equivalent & Substitute Parts

Part Overview

The MAF94133 is a dual-band RF whip antenna manufactured by TE Connectivity Laird, designed for 2.4GHz and 5.5GHz frequency applications. This component operates across the frequency ranges of 2.4GHz ~ 2.5GHz and 4.9GHz ~ 6GHz with a gain of 3.6dBi and features a straight whip configuration with SMA Male connector termination.

The MAF94133 is classified as an obsolete product. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this antenna.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAF94133 are identified based on the following critical parameters that determine functional compatibility:

Frequency Coverage: Both the main part and substitute must operate across the dual-band frequency ranges of 2.4GHz ~ 2.5GHz and 4.9GHz ~ 6GHz.

Connector Type: The SMA Male termination is a mandatory requirement for mechanical and electrical compatibility with existing RF circuits.

Antenna Configuration: The whip antenna type and mounting method (Connector Mount) must be maintained to ensure physical integration compatibility.

Electrical Performance: VSWR specification of 2 and dual-band operation are core functional requirements.

Series Alignment: Parts within the TE Connectivity Laird WTS series maintain consistent design standards and performance characteristics.

The MAF94271 qualifies as a substitute based on these parameters. While it features a tilt configuration rather than straight, and exhibits different gain values (2.1dBi and 3.4dBi), it maintains identical frequency coverage, connector type, mounting method, VSWR specification, and series designation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAF94133 is obsolete, while the MAF94271 maintains active product status. Selection of the MAF94271 ensures access to current manufacturing, quality assurance processes, and ongoing vendor support.

Compliance and Certification: The MAF94271 is RoHS3 Compliant, meeting current regulatory requirements for electronic components. Both parts share identical ECCN classification (5A991G), indicating equivalent export control status.

Frequency and Connector Compatibility: Both parts operate across identical frequency ranges and utilize SMA Male connectors, ensuring direct electrical compatibility with existing RF circuit designs.

Gain Differential: The MAF94271 provides dual gain specifications (2.1dBi and 3.4dBi) compared to the single 3.6dBi specification of the MAF94133. System designs requiring the specific 3.6dBi gain characteristic must evaluate whether the 3.4dBi performance of the MAF94271 meets operational requirements.

Physical Configuration: The transition from straight to tilt antenna configuration requires verification of mechanical clearance and mounting space within the target application enclosure.

Frequently Asked Questions (FAQ)

Q: Can the MAF94271 directly replace the MAF94133 in existing designs?

A: Electrical compatibility is established through identical frequency ranges, VSWR specification, and SMA Male connector termination. Physical compatibility requires verification of available mounting space, as the MAF94271 features a tilt configuration with a maximum height of 3.776" (95.90mm), whereas the MAF94133 is a straight whip antenna.

Q: What is the significance of the gain difference between these parts?

A: The MAF94133 specifies 3.6dBi gain, while the MAF94271 provides 2.1dBi and 3.4dBi. Gain affects antenna directivity and signal strength. Applications with strict gain requirements must confirm that the 3.4dBi maximum of the MAF94271 satisfies performance specifications.

Q: Are there packaging differences between these parts?

A: The MAF94133 packaging is listed as "-" (unspecified), while the MAF94271 is supplied in Bulk packaging. Procurement quantities and handling procedures may differ accordingly.

Q: Why is the MAF94271 listed as active while the MAF94133 is obsolete?

A: Product status reflects current manufacturing availability and vendor support. The MAF94271 remains in active production, ensuring supply chain continuity and access to current quality standards and certifications.

Q: Do both parts meet the same regulatory standards?

A: Both parts share identical ECCN classification (5A991G) and HTSUS codes within their respective categories. The MAF94271 is explicitly RoHS3 Compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What applications are supported by the MAF94271?

A: The MAF94271 is specified for Wi-Fi and WLAN applications, indicating suitability for wireless networking systems operating in the 2.4GHz and 5.5GHz bands.
