CAF95952 RF Antenna 850MHz Panel SMA Female Chassis Mount - Equivalent & Substitute Parts

Part Overview

The CAF95952 is an 850MHz panel RF antenna manufactured by TE Connectivity Laird, designed for UHF applications in the 806MHz to 960MHz frequency range. This component features SMA female termination with chassis mount configuration, delivering 3dBi gain at 50W maximum power handling. The part is classified as obsolete, necessitating identification of active equivalent or substitute components for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAF95952 is determined by strict alignment of electrical and mechanical parameters within the UHF panel antenna category. The following criteria establish substitution validity:

Primary Matching Criteria:

• Center frequency: 850MHz
• Antenna type: Panel configuration
• Termination: SMA Female connector
• Frequency group: UHF band (300MHz – 1GHz)
• Power handling: Minimum 50W
• VSWR: 2 or better
• RoHS compliance: Required

Secondary Considerations:

• Mounting type may vary (chassis mount vs. bracket mount) based on application requirements
• Gain variation is acceptable within system design parameters
• Frequency range overlap must encompass critical operating bands

The CAF95978 qualifies as a substitute based on matching center frequency, antenna type, termination standard, frequency group, power rating, VSWR specification, and RoHS compliance. Mounting type differs (bracket vs. chassis), requiring mechanical redesign consideration.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Electrical Compatibility):

The CAF95978 provides electrical and functional equivalence to the CAF95952 across all critical RF parameters: identical center frequency (850MHz), antenna type (panel), termination (SMA female), VSWR (2), and power handling (50W). Both components operate within the UHF frequency group and maintain RoHS compliance.

For System Integration:

Selection between these components depends on mechanical constraints. The CAF95952 uses chassis mount configuration, while the CAF95978 employs bracket mount. Applications requiring chassis-mounted installation must either redesign the mechanical interface or source alternative chassis-mount solutions. The CAF95978's higher gain (7.5dBi vs. 3dBi) may require system-level RF budget recalculation.

For New Designs:

The CAF95978 is the recommended choice for new development due to active product status and current manufacturing availability. The CAF95952's obsolete classification limits long-term supply viability.

Compliance Verification:

Both components satisfy RoHS requirements. The CAF95952 carries ECCN 5A991G classification, while the CAF95978 is classified as EAR99. Applications subject to export control regulations must verify compliance with applicable jurisdictional requirements.

Frequently Asked Questions (FAQ)

Q: Can the CAF95978 directly replace the CAF95952 in existing assemblies?

A: Electrical substitution is valid. The CAF95978 matches all RF specifications (frequency, termination, gain, power handling, VSWR). However, the mounting type differs (bracket vs. chassis), requiring mechanical redesign of the installation interface.

Q: What is the frequency range difference between these parts?

A: The CAF95952 operates 806MHz – 960MHz; the CAF95978 operates 806MHz – 869MHz. The substitute's range is narrower but encompasses the primary 850MHz center frequency and the critical 806MHz – 869MHz band. Applications requiring operation above 869MHz cannot use the CAF95978.

Q: Does the higher gain of the CAF95978 affect system performance?

A: The CAF95978 provides 7.5dBi gain versus the CAF95952's 3dBi. This 4.5dB increase improves antenna efficiency but requires RF budget recalculation in the receiving and transmitting paths. System designers must account for this gain differential in link budget analysis.

Q: Are there supply chain advantages to using the CAF95978?

A: Yes. The CAF95978 is classified as active product status with current manufacturing, ensuring ongoing availability. The CAF95952 is obsolete, presenting long-term supply risk for maintenance and production support.

Q: What are the export control implications?

A: The CAF95952 is classified ECCN 5A991G; the CAF95978 is EAR99. Applications subject to export licensing must verify compliance with current regulations for the selected component.

Q: Can mounting type be easily converted between chassis and bracket configurations?

A: Conversion depends on application-specific mechanical design. Chassis mount and bracket mount represent different physical interfaces requiring distinct mechanical hardware and installation procedures. Engineering evaluation of the specific application is necessary.
