RF Antenna 5604160 – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5604160 is a 900MHz whip straight RF antenna designed for UHF applications in the 890MHz to 960MHz frequency band. This component features a 2.15dBi gain, N-type female termination, and bracket mount configuration with a maximum height of 88.90mm. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system redesign, maintenance, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5604160 is determined by the following critical parameters:

• Frequency Compatibility: Center frequency of 900MHz with operational range 890MHz–960MHz
• Termination Type: N-type female connector for direct interface compatibility
• Frequency Group: UHF band (300MHz–1GHz)
• Regulatory Compliance: RoHS compliance status
• Electrical Performance: Gain specification within acceptable operational range

The substitute part TRA8903P (TE Connectivity Laird) meets these core electrical and mechanical compatibility criteria. While the antenna type differs (dome vs. whip) and mounting configuration changes (panel mount vs. bracket mount), the electrical parameters—frequency band, termination type, and gain performance—align with substitution requirements for 900MHz UHF applications.

Parameter Comparison

Engineering Selection Recommendations

The TRA8903P qualifies as an electrical substitute for the 5604160 based on matching frequency band (900MHz, 890–960MHz range), identical N-type female termination, and RoHS compliance. Both components operate within the UHF frequency group and support GSM/cellular applications.

Design integration requires evaluation of the following differences:

• Antenna Form Factor: The TRA8903P uses a dome configuration versus the whip design of the 5604160. Dome antennas provide omnidirectional radiation patterns suitable for fixed installations, while whip antennas offer directional characteristics.
• Mounting Architecture: Panel mount (TRA8903P) versus bracket mount (5604160) necessitates mechanical redesign of the mounting interface.
• Physical Envelope: The TRA8903P height of 68.58mm is 20.32mm shorter than the 5604160, reducing overall system height.
• Gain Performance: The TRA8903P provides 3dBi gain compared to 2.15dBi, representing a 0.85dB improvement in radiated power efficiency.

Both components maintain active or compliant regulatory status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can the TRA8903P directly replace the 5604160 without circuit modification?

A: Both components share identical N-type female termination and operate across the same 890–960MHz frequency band. However, mechanical mounting differs (panel mount vs. bracket mount), requiring enclosure or bracket redesign. Antenna form factor differences (dome vs. whip) may affect radiation pattern characteristics in the application.

Q: What is the significance of the gain difference between 2.15dBi and 3dBi?

A: The 0.85dB gain increase in the TRA8903P results in proportionally higher radiated power efficiency. This difference is measurable in link budget calculations but does not prevent functional substitution in most 900MHz UHF applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5604160 and TRA8903P are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What does the VSWR specification of 2 for the TRA8903P indicate?

A: VSWR (Voltage Standing Wave Ratio) of 2 indicates acceptable impedance matching at the N-type connector. The 5604160 does not specify VSWR; however, both components are designed for 50-ohm RF systems standard in UHF applications.

Q: Does the shorter height of the TRA8903P affect performance?

A: The 20.32mm height reduction does not degrade electrical performance. Antenna gain and frequency response remain independent of physical height within the specified operational envelope. The reduced height may improve mechanical integration in space-constrained designs.

Q: What packaging considerations apply to these parts?

A: The 5604160 is supplied in standard packaging (obsolete status). The TRA8903P is supplied in bulk packaging. Verify packaging requirements for production assembly and logistics planning.
