Phoenix Contact 2884936 RF Antenna Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2884936 is a 2.4GHz panel RF antenna with SMA female chassis mount termination, designed for UHF frequency applications in the 2.3GHz to 2.5GHz band. This component delivers 8dBi gain with IP55 ingress protection and is RoHS compliant. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2884936 is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency coverage: Must support the 2.4GHz band (2.3GHz ~ 2.5GHz minimum)
• Antenna type: Panel configuration
• Mounting interface: Chassis mount
• Physical envelope: Height compatibility at 101.00mm maximum
• Ingress protection: IP55 minimum rating
• Regulatory compliance: RoHS compliance required

Secondary Compatibility Factors:

• Termination type: SMA female preferred for direct mechanical compatibility
• Gain specification: 8dBi nominal (±1dBi acceptable range)
• VSWR performance: 1.5 or better

The Phoenix Contact 2701186 qualifies as a substitute based on shared frequency band coverage, panel antenna type, chassis mount configuration, and identical physical height. However, termination type differs (N Type Female vs. SMA Female), requiring connector adaptation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2701186 is an active production substitute for the obsolete 2884936. Both components share identical physical dimensions, panel antenna configuration, and chassis mount interface. The 2701186 provides enhanced environmental protection (IP67 vs. IP55) and maintains current RoHS3 compliance status, supporting long-term supply chain continuity.

The primary design consideration is termination compatibility. The 2701186 uses N Type Female termination rather than SMA Female. System integration requires either:

• Replacement of existing SMA connectors with N Type Female connectors
• Implementation of SMA-to-N Type adapter cables

The 2701186 delivers 1dBi higher gain (9dBi vs. 8dBi) and adds dual-band capability (2.4GHz and 5GHz coverage). For applications requiring single-band 2.4GHz operation with SMA termination, connector adaptation is necessary. For applications supporting dual-band operation or where N Type termination is acceptable, direct substitution is feasible.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2701186 directly replace the 2884936 without modifications?

A: Physical and mounting compatibility is direct. Electrical integration requires connector adaptation due to termination type difference (N Type Female vs. SMA Female). Existing SMA-terminated cables require replacement or adapter implementation.

Q: What is the impact of the 1dBi gain difference between these antennas?

A: The 2701186 provides 9dBi gain compared to the 2884936's 8dBi gain. This 1dBi increase represents approximately 26% higher effective radiated power in the 2.4GHz band. System link budget calculations should account for this performance improvement.

Q: Is the IP67 rating of the 2701186 compatible with applications designed for IP55?

A: Yes. IP67 (dust-tight, immersion to 1 meter) exceeds IP55 (dust-protected, water jets) environmental protection requirements. The 2701186 provides enhanced environmental sealing suitable for more demanding deployment conditions.

Q: Does the dual-band capability of the 2701186 affect 2.4GHz-only system operation?

A: No. The 2701186 operates independently in the 2.4GHz band (2.4GHz ~ 2.5GHz) with specified performance parameters. The 5GHz band capability does not impact single-band 2.4GHz applications.

Q: What compliance certifications apply to the 2701186 for new designs?

A: The 2701186 is ROHS3 compliant and REACH affected. Both certifications meet current regulatory requirements for electronic component deployment in EU and international markets.

Q: Are there physical envelope constraints when substituting the 2701186?

A: Both antennas share identical maximum height (101.00mm). Mechanical mounting interfaces are compatible. No physical envelope modifications are required for chassis mount installation.
