Phoenix Contact 2867021 - 900 MHz Transmission System Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2867021 is a 900 MHz RF Transmitter and Receiver Set designed for general-purpose wireless applications operating in the 902–928 MHz frequency band. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and new designs requiring similar functionality.

The primary function of this transmission system is bidirectional RF communication within the ISM band. Substitute parts must maintain compatibility with the 900 MHz frequency range and support equivalent transmission and reception capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 2867021 are grouped based on functional equivalence within the 900 MHz ISM band. The substitution logic is determined by the following criteria:

Primary Substitution Criteria:

• Operating frequency within or compatible with the 900–928 MHz band
• Bidirectional RF communication capability (transmitter and receiver functionality)
• General-purpose wireless application suitability
• RoHS and regulatory compliance alignment

Substitute Categories:

1. Active Transceiver Modules (2702877, 2901540): These parts provide integrated transmitter and receiver functionality at 900 MHz with active product status, making them direct functional replacements for the obsolete 2867021.

2. Antenna Components (2904801): Supporting RF infrastructure for 900 MHz systems, used in conjunction with transceiver modules to complete transmission system implementations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement:

Part 2702877 (RADIOLINE 900 MHz Transceiver) provides the most direct substitution for the 2867021. Both are Phoenix Contact components operating at 900 MHz with active inventory status. The 2702877 is RoHS3 compliant and rated for industrial environments (NEMA 4 enclosure rating), supporting general-purpose wireless applications.

Part 2901540 (900 MHz RADIOLINE Radio Module) offers an alternative with enhanced receiver sensitivity (−112 dBm versus −95 dBm) and integrated modem functionality with RS-232 and RS-485 interfaces. This part is suitable for applications requiring serial communication protocols.

For System Integration:

Part 2904801 (900 MHz ISM Whip Antenna) is a complementary component for complete transmission system implementation. The antenna provides 2.15 dBi gain with RP-SMA Male termination and includes 1.8 m cable with bracket mounting, supporting the RF infrastructure requirements of 900 MHz systems.

All substitute parts maintain ROHS3 compliance and are classified as active products with current inventory availability, ensuring long-term supply chain reliability compared to the obsolete 2867021.

Frequently Asked Questions (FAQ)

Q: Can the 2702877 directly replace the 2867021 in existing systems?

A: The 2702877 provides equivalent 900 MHz transmitter and receiver functionality. System integration depends on mechanical form factor, connector types, and voltage supply compatibility. The 2702877 requires 10.8–30.5 V supply and uses standard RF connectors, which must be verified against the original 2867021 installation specifications.

Q: What is the difference between the 2702877 and 2901540 transceivers?

A: Both operate at 900 MHz with 500 kbps data rate and 10.8–30.5 V supply. The 2901540 includes integrated modem functionality with RS-232 and RS-485 serial interfaces and provides superior receiver sensitivity (−112 dBm). The 2702877 is a simpler transceiver module without serial interfaces. Selection depends on whether serial communication protocols are required.

Q: Is the 2904801 antenna required for system operation?

A: The 2904801 is an RF antenna component designed for 900 MHz ISM applications. Its necessity depends on the original 2867021 system architecture. If the 2867021 included integrated antenna functionality, the 2904801 may be required as a separate component in substitute implementations.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 2702877, 2901540, and 2904801 are all ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The original 2867021 is RoHS compliant, ensuring regulatory consistency across substitution options.

Q: What is the packaging format for substitute parts?

A: The 2702877 and 2901540 are supplied in bulk packaging. The 2904801 antenna is also bulk packaged. Packaging specifications should be confirmed with procurement requirements for your application.
