Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAF29177 is based on the following critical parameters that must align for functional equivalence:

Primary Substitution Criteria:

• Frequency Band: 2.4GHz operation
• Termination Type: TNC Male connector
• Series Compatibility: TE Connectivity Laird WXE series
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Physical Form Factor: Antenna height and mounting compatibility

The WXE2400TNX qualifies as a substitute based on shared frequency band operation (2.4GHz), identical TNC Male termination, same manufacturer (TE Connectivity Laird), and equivalent MSL rating. Both components operate within the 2.4GHz frequency range and utilize TNC Male connectors for system integration.

Parameter Comparison

Engineering Selection Recommendations

For CAF29177 Replacement:

The WXE2400TNX serves as the active production equivalent for the obsolete CAF29177. Both components share the same manufacturer (TE Connectivity Laird), operate at 2.4GHz frequency band, utilize TNC Male termination, and maintain identical MSL 1 (Unlimited) moisture sensitivity ratings. The WXE2400TNX is currently in active production status, ensuring availability and supply chain continuity.

Compliance Considerations:

The WXE2400TNX carries RoHS Compliant certification, meeting modern environmental and regulatory standards. The ECCN classification differs between the two parts (5A991G for CAF29177 versus EAR99 for WXE2400TNX), which may affect export and regulatory documentation requirements depending on end-use application and destination.

Physical and Electrical Alignment:

Both antennas maintain equivalent maximum heights of 5.5" (139.70mm) and connector mount configurations. The WXE2400TNX provides documented electrical specifications including 3dBi gain, VSWR of 2, and maximum power rating of 50 W, enabling precise system performance validation. The antenna type differs (dipole versus whip/straight configuration), but both operate within the identical 2.4GHz frequency band required for system compatibility.

Frequently Asked Questions (FAQ)

Q: Can the WXE2400TNX directly replace the CAF29177 in existing installations?

A: The WXE2400TNX is electrically and mechanically compatible with systems designed for the CAF29177. Both components operate at 2.4GHz, utilize TNC Male connectors, and maintain equivalent physical dimensions (5.5" height). The primary difference is antenna form factor (dipole versus whip/straight), which does not prevent functional substitution in connector-mount applications.

Q: What is the significance of the different antenna types (dipole vs. whip)?

A: The CAF29177 uses a dipole configuration while the WXE2400TNX employs a whip/straight design. Both antenna types operate effectively at 2.4GHz and are suitable for RF applications in this frequency band. The choice between dipole and whip configurations depends on specific application requirements such as radiation pattern, mounting constraints, and spatial considerations. Both maintain TNC Male termination compatibility.

Q: Why do the ECCN classifications differ between these parts?

A: The CAF29177 carries ECCN 5A991G while the WXE2400TNX is classified as EAR99. These different export control classifications may affect regulatory documentation and international shipping requirements. Organizations must verify applicable export regulations for their specific end-use and destination markets when transitioning from the obsolete CAF29177 to the WXE2400TNX.

Q: Is the WXE2400TNX RoHS compliant?

A: Yes, the WXE2400TNX is RoHS Compliant. This certification ensures the component meets environmental and hazardous substance restrictions applicable to electronic equipment in regulated markets. The CAF29177 RoHS status is not specified in available documentation.

Q: What are the documented electrical specifications for the WXE2400TNX?

A: The WXE2400TNX provides the following electrical specifications: frequency range 2.4GHz ~ 2.5GHz, gain of 3dBi, VSWR of 2, and maximum power rating of 50 W. These specifications enable precise system design validation and performance prediction for RF applications requiring 2.4GHz operation.

Q: Are both components available in the same packaging?

A: Packaging information is not specified for the CAF29177. The WXE2400TNX is available with connector mount configuration. Both components feature TNC Male termination and equivalent physical dimensions, ensuring compatibility with standard RF connector interfaces.

Q: What inventory status should be considered when selecting between these parts?

A: The CAF29177 is obsolete and has limited availability (1147 Pcs noted as new original in stock at time of documentation). The WXE2400TNX is in active production status with current inventory of 874 Pcs, providing reliable supply chain access for ongoing and future applications.
