Phoenix Contact 2834669 General Purpose Relay DPDT 120VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834669 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 120VAC coil voltage. This relay is designed for DIN rail mounting with screw terminal connections and includes a lighted indicator, socket, and varistor protection. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834669 is determined by the following critical parameters:

• Coil Voltage: Must be 120VAC to maintain compatibility with existing control circuits
• Contact Form: Must be DPDT (2 Form C) to preserve switching functionality
• Mounting Type: Must be DIN Rail to fit existing installation infrastructure
• Termination Style: Must be Screw Terminal for direct connection compatibility
• Contact Rating: Substitute must support the required current load; lower ratings indicate reduced capacity
• Switching Voltage: Must accommodate the maximum voltage levels in the application circuit
• Coil Type: Must be Non Latching to match operational behavior

The Phoenix Contact 2903322 meets all critical substitution criteria while maintaining functional equivalence for general purpose relay applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903322 is the designated substitute for the obsolete 2834669 relay. Both components share identical coil voltage (120VAC), contact form (DPDT), mounting configuration (DIN Rail), and termination style (Screw Terminal).

Key considerations for selection:

• The 2903322 operates at 8.5A contact rating compared to the 2834669's 10A rating. Applications requiring the full 10A capacity must evaluate load requirements against the substitute's reduced rating.
• The 2903322 features enhanced DC switching capability (250VDC maximum versus 125VDC), providing broader voltage compatibility.
• The 2903322 maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.
• Operating temperature range differs: the 2903322 supports -40°C to 50°C versus the original -25°C to 60°C. Applications operating at temperature extremes require verification against the substitute's narrower upper limit.
• Switching response times are longer for the 2903322 (15ms operate, 20ms release versus 10ms and 12ms respectively). Time-critical applications must confirm compatibility with these extended response characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903322 directly replace the 2834669 in all applications?

A: The 2903322 is functionally equivalent for general purpose relay applications with identical coil voltage, contact form, and mounting configuration. However, applications requiring the full 10A contact rating or operating at temperatures above 50°C require evaluation against the substitute's specifications.

Q: What is the primary difference in contact rating between these relays?

A: The 2834669 is rated for 10A continuous contact current, while the 2903322 is rated for 8.5A. Applications operating near maximum current capacity must confirm the substitute's reduced rating is acceptable for the intended load.

Q: Are the switching response times interchangeable?

A: No. The 2834669 operates in 10ms and releases in 12ms, while the 2903322 requires 15ms to operate and 20ms to release. Applications with timing-dependent logic must verify compatibility with the longer response times of the substitute.

Q: What is the difference in contact material between these relays?

A: The 2834669 uses pure Silver (Ag) contacts, while the 2903322 uses Silver Nickel (AgNi) contacts. Both materials are suitable for general purpose switching; the AgNi composition in the substitute provides enhanced durability for extended cycle life.

Q: Does the 2903322 support the same voltage switching range?

A: The 2903322 supports 250VAC and 250VDC maximum switching voltage, compared to the 2834669's 250VAC and 125VDC. The substitute provides enhanced DC voltage capability, making it suitable for a broader range of circuit configurations.

Q: Are both relays RoHS compliant?

A: Yes. The 2834669 is RoHS Compliant, and the 2903322 is ROHS3 Compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the coil current difference, and does it affect circuit design?

A: The 2834669 draws 9mA coil current, while the 2903322 draws 13mA. Control circuits must provide sufficient current capacity for the substitute's higher coil current requirement.
