Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2900982 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Termination type: SMA Male (electrical interface requirement)
• Mounting type: Bracket Mount (mechanical interface requirement)
• Cable length: 5m (system integration requirement)
• Frequency band coverage: Must include all five bands of the original part (850MHz, 900MHz, 1.8GHz, 1.9GHz, 2.1GHz)
• Antenna form factor: Whip, Straight configuration

Allowable Variations:

• Gain: May differ from 2dBi if frequency coverage is maintained
• Height: May vary within system constraints
• Ingress protection rating: May be different if application environment permits
• Product status: Active parts are preferred for obsolete replacements

The Phoenix Contact 2702273 qualifies as a substitute because it maintains all mandatory compatibility criteria while offering extended frequency coverage and higher gain options.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2702273 is the designated substitute for the obsolete 2900982 based on the following engineering factors:

Compliance and Regulatory Status: The 2702273 maintains RoHS compliance with ROHS3 certification and includes REACH unaffected status, meeting current regulatory requirements. The original 2900982 is RoHS compliant but obsolete.

Electrical Interface Compatibility: Both parts feature SMA Male termination and 5m cable configuration, ensuring direct electrical compatibility with existing system designs.

Mechanical Interface Compatibility: Both parts utilize bracket mount configuration, maintaining mechanical compatibility with existing mounting structures.

Frequency Coverage: The 2702273 provides extended frequency band coverage (700MHz through 2.6GHz) that encompasses all five bands of the original 2900982, ensuring backward compatibility for GSM and UMTS applications.

Physical Form Factor: The 2702273 maintains the whip, straight antenna configuration. The reduced maximum height (82.00mm versus 347.00mm) may require verification for space-constrained installations.

Gain Characteristics: The 2702273 offers selectable gain options (3dBi, 4dBi, 5dBi) compared to the fixed 2dBi of the original part. System performance characteristics should be evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2702273 directly replace the 2900982 in existing installations?

A: Yes, for applications requiring the five frequency bands of the original part (850MHz, 900MHz, 1.8GHz, 1.9GHz, 2.1GHz). Both parts share identical SMA Male termination, bracket mount configuration, and 5m cable length. Physical space availability must be confirmed due to the reduced antenna height of the 2702273.

Q: What are the key differences between these two antenna models?

A: The primary differences are product status (2900982 is obsolete; 2702273 is active), frequency band coverage (2702273 supports eight bands versus five), gain options (2702273 offers 3dBi, 4dBi, or 5dBi versus fixed 2dBi), and physical height (2702273 is significantly shorter at 82.00mm). Both maintain identical electrical and mechanical interfaces.

Q: Are there any compliance or certification differences?

A: The 2702273 carries ROHS3 and REACH unaffected certifications, representing current regulatory standards. The 2900982 is RoHS compliant but obsolete. For new designs or systems requiring current compliance documentation, the 2702273 is the appropriate selection.

Q: Does the gain difference affect system performance?

A: The 2702273 offers higher gain options (3dBi to 5dBi) compared to the original 2dBi. System performance impact depends on application requirements and link budget calculations. Gain selection should be based on specific deployment conditions.

Q: Is the reduced antenna height of the 2702273 a limitation?

A: The 2702273 maximum height of 82.00mm is significantly shorter than the 2900982 at 347.00mm. Installation feasibility depends on available mounting space and environmental clearance requirements. Physical verification is necessary for space-constrained applications.

Q: Can the 2702273 be used for applications beyond GSM and UMTS?

A: The 2702273 supports extended frequency coverage including 700MHz, 800MHz, and 2.6GHz bands beyond the original GSM/UMTS specification. Application suitability depends on system design requirements and frequency band utilization.
