Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2987011 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Contact Form: SPDT (1 Form C)
• Contact Rating (Current): 6 A
• Mounting Type: DIN Rail
• Termination Style: Spring Terminal
• Operating Temperature Range: -40°C ~ 70°C
• Contact Material: Silver Tin Oxide (AgSnO)
• Relay Type: General Purpose

Allowable Variation Parameters:

• Coil Voltage: May differ based on system design requirements
• Coil Current: Varies with coil voltage selection
• Operate/Release Time: Acceptable variation within application tolerance
• Product Status: Active status preferred for new procurement
• Compliance Certifications: RoHS3 compliance acceptable as upgrade from RoHS

The substitute part Phoenix Contact 2900318 maintains all mandatory matching parameters while offering an active product status and enhanced compliance certifications. The primary difference is coil voltage specification (12VDC versus 24VDC), which requires circuit design consideration during implementation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900318 is the designated substitute for the obsolete 2987011 relay. Selection of this substitute is supported by the following engineering factors:

Product Status Consideration: The 2987011 is obsolete, limiting availability for future procurement. The 2900318 maintains active product status, ensuring supply chain continuity and long-term component availability.

Compliance Upgrade: The 2900318 provides ROHS3 compliance, representing an enhancement over the RoHS compliance of the original part. Both parts maintain EAR99 export classification and are suitable for regulated applications.

Functional Equivalence: Both relays maintain identical contact form (SPDT), current rating (6A), switching voltage capability (250VAC/250VDC), and operating temperature range (-40°C to 70°C). Spring terminal termination and socket inclusion are preserved in the substitute.

Circuit Design Requirement: Implementation of the 2900318 requires coil voltage adjustment from 24VDC to 12VDC. This substitution is applicable only in systems where the control circuit can be modified to supply 12VDC to the relay coil. The substitute exhibits faster switching response (4ms operate and release time versus 8ms and 11ms), which may require timing circuit evaluation in time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the 2900318 be used as a direct drop-in replacement for the 2987011?

A: The 2900318 is mechanically and functionally compatible for DIN rail mounting and contact switching operations. However, coil voltage differs (12VDC versus 24VDC), requiring control circuit modification. Direct socket compatibility is maintained through included socket provisions in both designs.

Q: What is the primary reason for substitution?

A: The 2987011 is obsolete. The 2900318 provides equivalent relay functionality with active product status, ensuring component availability and supply chain reliability for future maintenance and replacement needs.

Q: Are there differences in switching speed between these relays?

A: Yes. The 2900318 operates in 4ms and releases in 4ms, compared to 8ms operate and 11ms release for the 2987011. Applications with timing-critical switching requirements must evaluate this performance difference.

Q: Do both relays support the same contact switching voltage?

A: Yes. Both relays are rated for 250VAC and 250VDC maximum switching voltage, maintaining identical load-switching capability across AC and DC applications.

Q: What is the packaging difference between these parts?

A: The 2987011 is packaged as individual units, while the 2900318 is supplied in bulk packaging. Both are suitable for DIN rail installation with spring terminal connections.

Q: Are there compliance differences?

A: The 2900318 provides ROHS3 compliance, which supersedes the RoHS compliance of the 2987011. Both parts maintain EAR99 export classification and are REACH-affected (2900318 explicitly noted as REACH Affected).
