Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2885579 is determined by the following critical parameters:

• Frequency Alignment: Center frequency must be 900MHz to maintain system RF performance
• Termination Type: N Type Female connector is mandatory for mechanical and electrical compatibility
• Antenna Configuration: Whip, straight geometry ensures form factor compatibility
• Gain Specification: Acceptable gain range depends on system link budget requirements
• Mounting Interface: Physical mounting method must accommodate system integration constraints
• Compliance Status: RoHS and REACH certifications ensure regulatory compliance for target markets

The identified substitute part (Phoenix Contact 1361276) shares the core frequency, termination, and antenna type specifications. Differences in gain (5dB vs. 8dBi), mounting method (base mount vs. bracket mount), and ingress protection rating represent trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1361276 serves as the primary substitute for the obsolete 2885579 based on:

• Active Product Status: The 1361276 is actively manufactured and supported, ensuring long-term availability and supply chain stability
• Regulatory Compliance: ROHS3 compliance exceeds the RoHS requirement of the original part and includes REACH certification, meeting current environmental standards
• Core RF Compatibility: Identical 900MHz center frequency and N Type Female termination ensure RF system compatibility without redesign of connector interfaces
• Antenna Geometry: Matching whip, straight configuration maintains form factor consistency

Critical Differences Requiring Evaluation:

• Gain Reduction: The 1361276 provides 5dB gain versus 8dBi on the original part. System link budget analysis is required to determine if this 3dB reduction is acceptable for the intended application
• Mounting Method Change: Transition from bracket mount to base mount necessitates mechanical redesign of the antenna mounting structure
• Ingress Protection: The 1361276 does not specify an ingress protection rating, whereas the original part is rated IP65. Environmental exposure requirements must be assessed

Frequently Asked Questions (FAQ)

Q: Can the 1361276 be used as a direct replacement for the 2885579?

A: The 1361276 shares the critical RF parameters (900MHz frequency, N Type Female termination, whip antenna type) required for RF system compatibility. However, the mounting method differs (base mount vs. bracket mount), requiring mechanical integration changes. The gain difference (5dB vs. 8dBi) must be evaluated against system link budget requirements.

Q: What is the significance of the gain difference between these parts?

A: The 2885579 provides 8dBi gain while the 1361276 provides 5dB gain, representing a 3dB reduction. In RF systems, 3dB corresponds to a halving of power in the antenna's effective radiated power. System performance impact depends on transmit power levels, receiver sensitivity, and distance requirements.

Q: Why does the mounting type differ between these parts?

A: The 2885579 uses bracket mount configuration while the 1361276 uses base mount. These represent different mechanical integration approaches. Bracket mount typically attaches to vertical or angled surfaces, while base mount typically attaches to horizontal surfaces. The appropriate choice depends on the physical installation geometry of the target system.

Q: Are there compliance differences between these parts?

A: The 2885579 is RoHS Compliant. The 1361276 is ROHS3 Compliant and includes REACH Affected status. ROHS3 represents a more recent compliance standard. Both parts carry the same ECCN (EAR99) and HTSUS (8517.71.0000) classifications.

Q: What does the missing ingress protection rating on the 1361276 mean?

A: The 2885579 specifies IP65 protection, indicating dust-tight and water jet resistant performance. The 1361276 does not specify an ingress protection rating. If the application requires environmental protection equivalent to IP65, the environmental exposure conditions of the 1361276 must be independently assessed or alternative parts with specified ingress protection ratings must be considered.

Q: Is the 1361276 suitable for general purpose 900MHz applications?

A: The 1361276 is designated for general purpose applications and operates at 900MHz with N Type Female termination. It is suitable for general ISM band applications at this frequency. Specific application suitability depends on gain requirements, mounting constraints, and environmental protection needs.
