TE Connectivity Laird MAF94225 2.4GHz Whip Tilt RF Antenna Equivalent & Substitute Parts

Part Overview

The TE Connectivity Laird MAF94225 is a 2.4GHz whip tilt RF antenna with U.FL (UMCC) IPEX MHF1 base mount termination, designed for UHF frequency applications in the 2.4GHz to 2.5GHz band. The MAF94225 operates with a VSWR of 2 and is classified as an obsolete product. Due to its obsolete status, equivalent substitute parts with active product status are available to ensure design continuity and supply chain reliability for applications requiring 2.4GHz whip antenna functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAF94225 is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency range compatibility: 2.4GHz ~ 2.5GHz operation
• Antenna type classification: Whip configuration
• Termination connector: U.FL (UMCC) IPEX interface
• Mounting methodology: Base mount or connector mount
• VSWR specification: 2 or better
• Frequency group: UHF (2GHz ~ 3GHz)

Substitute Parts Identified:

1. MAF94402 - Direct functional equivalent with identical specifications and active product status
2. 0600-00057 - Frequency and termination compatible with configuration variation (straight whip vs. tilt whip)

Both substitute parts maintain the core electrical parameters (frequency range, VSWR, termination type) and mechanical compatibility (U.FL connector interface) required for application substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MAF94402

The MAF94402 is the direct equivalent substitute for the obsolete MAF94225. Both parts share identical electrical specifications (2.4GHz ~ 2.5GHz frequency range, VSWR of 2), mechanical dimensions (4.128" maximum height), termination type (U.FL UMCC IPEX MHF1), and mounting methodology (base mount). The MAF94402 maintains active product status with RoHS compliance certification, ensuring long-term supply availability and regulatory alignment for new designs or production continuations.

Secondary Recommendation: 0600-00057

The 0600-00057 serves as a frequency and electrical compatible alternative when design constraints permit configuration variation. This part operates within the identical 2.4GHz ~ 2.5GHz frequency band with matching VSWR performance. However, the 0600-00057 differs in antenna orientation (straight whip vs. tilt whip) and mounting methodology (connector mount vs. base mount). The 0600-00057 provides documented electrical performance metrics (Return Loss -10dB, Gain 2dBi) and RoHS compliance. Selection of this part requires verification that the straight whip configuration and connector mount interface are compatible with the target application's physical and electrical requirements.

Frequently Asked Questions (FAQ)

Q1: Can MAF94402 be used as a direct replacement for MAF94225?

A: Yes. The MAF94402 is a direct functional equivalent. Both parts operate at 2.4GHz center frequency with 2.4GHz ~ 2.5GHz frequency range, maintain VSWR of 2, use U.FL (UMCC) IPEX MHF1 termination, employ base mount methodology, and share identical maximum height specifications (4.128"). The MAF94402 holds active product status, making it the preferred substitute for the obsolete MAF94225.

Q2: What is the key difference between MAF94402 and 0600-00057?

A: The primary differences are antenna orientation and mounting type. MAF94402 features a tilt whip antenna with base mount, matching the MAF94225 configuration. The 0600-00057 features a straight whip antenna with connector mount termination. Both maintain frequency compatibility (2.4GHz ~ 2.5GHz) and VSWR performance (2). Selection depends on whether the application requires tilt vs. straight antenna geometry and base mount vs. connector mount interface.

Q3: Are there connector compatibility issues between IPEX MHF1 and IPEX MHF4?

A: IPEX MHF1 and IPEX MHF4 are distinct connector variants within the U.FL (UMCC) family. MAF94225 and MAF94402 use IPEX MHF1 termination. The 0600-00057 uses IPEX MHF4 termination. These connectors are not interchangeable. Connector selection must match the PCB or host device interface specification. Verify the target application's connector requirement before selecting 0600-00057.

Q4: Does the 0600-00057 provide better electrical performance than MAF94225?

A: The 0600-00057 provides documented electrical performance specifications (Return Loss -10dB, Gain 2dBi) that are not specified for the MAF94225. Both parts maintain identical VSWR (2) and frequency range (2.4GHz ~ 2.5GHz). The documented gain and return loss values for 0600-00057 indicate measurable performance characteristics; however, these specifications reflect the straight whip configuration and may not be directly comparable to the tilt whip design of MAF94225 without application-specific testing.

Q5: What is the significance of product status (Obsolete vs. Active)?

A: Product status indicates supply chain availability and manufacturer support. The MAF94225 is classified as obsolete, meaning TE Connectivity Laird has discontinued active production and support. Both MAF94402 and 0600-00057 maintain active status, ensuring continued manufacturing, availability, and technical support. For new designs or production continuations, active-status parts are recommended to avoid future supply disruptions.

Q6: Are MAF94402 and 0600-00057 RoHS compliant?

A: Yes. Both MAF94402 and 0600-00057 are certified RoHS compliant. The MAF94225 RoHS status is not specified in the provided documentation. For applications requiring RoHS compliance certification, both substitute parts meet this regulatory requirement.

Q7: What does MSL 1 (Unlimited) mean for these antenna parts?

A: Moisture Sensitivity Level (MSL) 1 with unlimited rating indicates the lowest moisture sensitivity classification. These parts require no special moisture control during storage, handling, or assembly. Standard warehouse and manufacturing conditions are acceptable without desiccant packaging or controlled humidity environments.
