Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAF94151 are identified based on strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Frequency Range: 2.4GHz ~ 2.5GHz
• Frequency Group: UHF (2GHz ~ 3GHz)
• Antenna Type: Whip, Tilt configuration
• Termination: U.FL (UMCC), IPEX MHF1 connector interface
• Number of Bands: Single band operation

Allowable Variation Parameters:

• Mounting Type: Base Mount or Connector Mount (both support the same connector interface)
• Height: Physical dimensions may vary within practical design constraints
• VSWR: Electrical performance specifications may differ
• Gain: Additional performance characteristics may be present in substitutes

The W1049B030 from Pulse Electronics meets all mandatory matching criteria and is classified as an active product with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MAF94151 is obsolete and no longer in active production. The W1049B030 is an active product with current manufacturing support from Pulse Electronics, ensuring ongoing availability and supply chain reliability.

Compliance and Certification: The W1049B030 carries REACH Unaffected status and is classified under ECCN EAR99, indicating standard commercial export classification. The MAF94151 is classified under ECCN 5A991G. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental handling requirements.

Physical and Electrical Compatibility: Both antennas utilize identical U.FL (UMCC) IPEX MHF1 connector termination, ensuring direct mechanical and electrical compatibility at the interface level. The W1049B030 features a shorter maximum height (3.248 inches versus 4.128 inches), which may be advantageous in space-constrained applications. The W1049B030 specifies 2dBi gain, providing documented performance characteristics for link budget calculations.

Mounting Configuration: The MAF94151 uses base mount configuration, while the W1049B030 uses connector mount configuration. Both mounting types are compatible with U.FL (UMCC) IPEX MHF1 interfaces and support equivalent installation methods in typical PCB-based wireless systems.

Frequently Asked Questions (FAQ)

Q: Can the W1049B030 directly replace the MAF94151 in existing designs?

A: Yes. Both antennas share identical frequency range (2.4GHz ~ 2.5GHz), antenna type (whip, tilt), and connector termination (U.FL UMCC IPEX MHF1). The connector interface is mechanically and electrically compatible, allowing direct substitution at the component level.

Q: What is the difference between base mount and connector mount configurations?

A: Base mount antennas attach directly to a PCB-mounted base structure. Connector mount antennas attach via the connector interface itself. Both configurations support the same U.FL (UMCC) IPEX MHF1 connector and are compatible with standard wireless module designs.

Q: Does the height difference between MAF94151 (4.128") and W1049B030 (3.248") affect performance?

A: Height differences in whip antennas affect physical form factor and may influence radiation pattern characteristics. The W1049B030's shorter height may be beneficial in applications with space constraints. Both antennas operate within the same frequency band and use identical connector termination.

Q: What does the 2dBi gain specification on the W1049B030 indicate?

A: The 2dBi gain represents the antenna's directional gain relative to an isotropic radiator. This specification is provided for the W1049B030 but not specified for the MAF94151. This additional performance data supports link budget analysis and system design calculations.

Q: Are there any compliance or regulatory differences between these parts?

A: The W1049B030 carries REACH Unaffected status and EAR99 classification. The MAF94151 carries ECCN 5A991G classification. Both parts carry identical MSL 1 (Unlimited) moisture sensitivity ratings. Compliance requirements should be verified against specific application and regional regulations.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. Both the MAF94151 and W1049B030 carry this rating, indicating equivalent environmental robustness.
