Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 2909531 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 12VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 10 A
• Switching voltage: 250VAC, 250VDC maximum
• Coil current: 33 mA
• Coil type: Non Latching
• Mounting type: DIN Rail
• Contact material: Silver Nickel (AgNi)
• Operating temperature range: -40°C ~ 60°C
• Features: Lighted Indicator, Socket Included

Two substitute parts meet these criteria. The first is the manufacturer-recommended substitute 2909518 from the PLC-RSC series, which maintains all electrical and mechanical parameters while differing only in termination style (Screw Terminal vs. Spring Terminal) and product status (Active). The second is the parametric equivalent 2900290 from the PLC-RPT series, which maintains identical electrical specifications and termination style while offering improved compliance status.

Engineering Selection Recommendations

Phoenix Contact 2909518 (MFR Recommended Substitute)

The 2909518 is the manufacturer-recommended substitute for the obsolete 2909531. Both parts are RoHS Compliant and share identical electrical and mechanical specifications. The primary distinction is the termination style: the 2909518 uses Screw Terminal connections instead of Spring Terminal. This substitution is appropriate for applications where screw terminal connections are compatible with existing wiring infrastructure. The 2909518 maintains Active product status, ensuring ongoing availability and support.

Phoenix Contact 2900290 (Parametric Equivalent)

The 2900290 is a parametric equivalent offering identical electrical performance and Spring Terminal termination matching the original 2909531. This part provides enhanced compliance status with ROHS3 Compliant certification and REACH Affected designation. The 2900290 is suitable for applications requiring direct mechanical and electrical compatibility with the original design while benefiting from improved regulatory compliance. Active product status ensures long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the 2909518 be used as a direct replacement for the 2909531?

A: The 2909518 is electrically and mechanically equivalent to the 2909531 across all critical parameters. The difference in termination style (Screw Terminal vs. Spring Terminal) requires assessment of compatibility with existing wiring connections. If the application accommodates screw terminal connections, the 2909518 is a suitable substitute.

Q: What is the difference between the 2909518 and 2900290 substitutes?

A: Both parts are electrically equivalent to the 2909531. The 2909518 uses Screw Terminal connections and belongs to the PLC-RSC series. The 2900290 uses Spring Terminal connections matching the original design and belongs to the PLC-RPT series. The 2900290 offers enhanced compliance with ROHS3 certification. Selection depends on termination style requirements and compliance specifications for the application.

Q: Why is the 2909531 obsolete?

A: The 2909531 has been discontinued by Phoenix Contact. The manufacturer recommends the 2909518 as the primary substitute. The 2900290 provides an alternative with identical termination style and enhanced compliance status.

Q: Are there any performance differences between these relays?

A: All three relays share identical electrical specifications: 12VDC coil voltage, 10A contact rating, 250VAC/250VDC switching voltage, 33mA coil current, 8ms operate time, and 10ms release time. Operating temperature range and contact material are identical. Differences are limited to product status, termination style, and regulatory compliance certifications.

Q: Which substitute should I select for new designs?

A: For new designs, the 2900290 is recommended due to its Active product status, Spring Terminal termination, and enhanced ROHS3 compliance. For applications requiring Screw Terminal connections, the 2909518 is the appropriate choice.
