Phoenix Contact 2903219 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2903219 is a 2.45GHz omnidirectional whip antenna designed for general-purpose RF applications in the UHF frequency band (2GHz ~ 3GHz). This component features an N-type female termination, bracket mounting, and 6dBi gain across the 2.4GHz to 2.5GHz frequency range. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2903219 is determined by strict equivalence across the following critical parameters:

Frequency compatibility: The substitute must operate across the identical 2.4GHz ~ 2.5GHz frequency range to ensure RF performance in target applications.

Antenna configuration: The substitute must maintain the whip, straight antenna type to preserve mechanical and electrical characteristics.

Electrical termination: The substitute must feature N-type female connectors for direct mechanical and electrical compatibility.

Mounting interface: The substitute must support bracket mounting to ensure installation compatibility with existing mechanical assemblies.

Gain specification: The substitute must deliver 6dBi gain to maintain system link budget and performance expectations.

The Phoenix Contact 2885919 meets all substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2885919 is the direct functional equivalent for the obsolete 2903219. Both components share identical frequency range, antenna type, gain, and termination specifications. The 2885919 is actively manufactured and carries current regulatory compliance certifications (ROHS3 and REACH).

Physical differences exist: the 2885919 has a reduced maximum height of 250.00mm compared to 330.00mm for the 2903219, and ingress protection is rated IP55 versus IP65. These differences must be evaluated against specific application requirements. The 2885919 provides a specified VSWR of 1.5, indicating controlled impedance matching across the operating frequency band.

For applications requiring the original 330.00mm height or IP65 environmental sealing, alternative Phoenix Contact antenna models should be consulted. For standard general-purpose 2.4GHz applications, the 2885919 provides equivalent RF performance with active product support and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 2885919 directly replace the 2903219 in existing installations?

A: The 2885919 provides electrical and RF equivalence across all critical parameters. Physical installation compatibility depends on mechanical envelope constraints. The reduced height (250.00mm vs. 330.00mm) and lower ingress protection rating (IP55 vs. IP65) must be verified against application requirements before substitution.

Q: What is the significance of the VSWR specification on the 2885919?

A: VSWR (Voltage Standing Wave Ratio) of 1.5 indicates the impedance matching quality of the antenna across its operating frequency range. Lower VSWR values represent better impedance matching and reduced signal reflection. The 2903219 does not specify VSWR; the 2885919 provides this measured parameter for system design purposes.

Q: Are there compliance differences between the two parts?

A: The 2885919 carries ROHS3 and REACH compliance certifications. The 2903219 specifications do not include these certifications. For applications subject to environmental or regulatory compliance requirements, the 2885919 meets current standards.

Q: What packaging options are available for the 2885919?

A: The 2885919 is supplied in bulk packaging. Original packaging specifications for the 2903219 are not provided in available documentation.

Q: How does the height difference affect antenna performance?

A: Antenna height influences radiation pattern and gain characteristics. Both components specify 6dBi gain across the 2.4GHz ~ 2.5GHz range. The physical height reduction from 330.00mm to 250.00mm may affect radiation pattern shape and mechanical mounting considerations but does not change the specified gain value.
