Phoenix Contact 2867791 RF Antenna 900MHz Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2867791 is a 900MHz whip straight RF antenna with N-type female termination, designed for bracket mount applications in the 902–928MHz ISM band. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The substitute part maintains core RF performance characteristics while offering improved product status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2867791 is determined by the following critical parameters:

• Frequency Compatibility: Center frequency of 900MHz with operational capability across the 902–928MHz ISM band
• Antenna Configuration: Whip, straight physical form factor
• Electrical Termination: N-type female connector
• Gain Performance: Minimum 5dB gain to maintain RF link budget
• Regulatory Compliance: RoHS and ECCN EAR99 classification

The substitute part 1361276 satisfies these core substitution criteria through matching frequency band, antenna type, termination standard, and regulatory status. Differences in mounting methodology (base mount vs. bracket mount) and gain specification (5dB vs. 5.15dBi) represent acceptable trade-offs within the ISM band application space.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1361276

The 1361276 is the manufacturer-recommended substitute for the obsolete 2867791. Both components are Phoenix Contact products with identical 900MHz center frequency, whip antenna configuration, and N-type female termination. The substitute maintains active product status with ROHS3 compliance, ensuring long-term supply chain viability and regulatory alignment.

The 0.15dB gain differential (5dB vs. 5.15dBi) is within typical ISM band system margins and does not constitute a functional limitation for general-purpose 900MHz applications. The transition from bracket mount to base mount requires mechanical integration review specific to the end-use enclosure design.

Frequently Asked Questions (FAQ)

Q: Can the 1361276 directly replace the 2867791 in existing designs?

A: Electrical substitution is valid based on matching frequency band, antenna type, and N-type female termination. Mechanical integration requires assessment of mounting methodology differences (bracket vs. base mount) within the specific application enclosure.

Q: What is the significance of the gain difference between 5.15dBi and 5dB?

A: The 0.15dB differential represents a negligible performance variance in ISM band systems. Both specifications support equivalent RF link budget calculations for 900MHz applications.

Q: Are there compliance considerations when transitioning from 2867791 to 1361276?

A: Both components carry EAR99 ECCN classification. The substitute offers enhanced regulatory status through ROHS3 compliance versus RoHS compliance on the obsolete part, supporting current supply chain and environmental requirements.

Q: Does the unspecified frequency range on the 1361276 affect substitution validity?

A: The 1361276 is specified for 900MHz general-purpose ISM band operation. The absence of explicit frequency range documentation does not alter functional equivalence for 902–928MHz band applications.

Q: What packaging differences exist between these parts?

A: The 2867791 is supplied in standard packaging, while the 1361276 is packaged in boxes. This distinction affects logistics and inventory management but does not impact electrical or mechanical performance.
