Phoenix Contact 2829564 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2829564 is a general purpose relay with SPST-NO (1 Form A) contact configuration, rated for 10A at 24VDC coil voltage. This socketable relay is designed for standard switching applications requiring reliable electromagnetic actuation. The product is currently obsolete, necessitating identification of functionally compatible alternatives for ongoing system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2829564 is evaluated based on the following critical parameters:

Mandatory Compatibility Criteria:

• Contact form: SPST-NO (1 Form A) configuration
• Coil voltage: 24VDC
• Relay type: General purpose
• Contact material compatibility with switching requirements

Allowable Variations:

• Contact rating current: The substitute part 1078683 is rated at 6A, which is lower than the original 10A rating. This represents a derating and is acceptable only for applications where the actual load current does not exceed 6A.
• Mounting type: The substitute transitions from socketable (plug-in) to DIN rail mounting, requiring mechanical integration changes.
• Termination style: The substitute uses spring terminals instead of plug-in termination.
• Operating temperature range: The substitute provides an extended range (-40°C ~ 60°C vs. -20°C ~ 50°C).
• Switching voltage: The substitute supports both 250VAC and 250VDC, providing additional flexibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1078683 is an active product that maintains functional compatibility with the obsolete 2829564 for SPST-NO switching applications at 24VDC. Both relays comply with RoHS requirements, with the substitute offering ROHS3 compliance and REACH affected status.

Selection of the 1078683 as a substitute requires verification that the application load current does not exceed 6A, as this represents the primary electrical derating compared to the original 10A specification. The transition from socketable to DIN rail mounting necessitates mechanical redesign of the installation interface. The substitute's lower coil current (18 mA vs. 28 mA) provides reduced power consumption in the control circuit.

The 1078683 includes a socket and lighted indicator feature not present in the original part, offering enhanced functionality for system diagnostics and maintenance.

Frequently Asked Questions (FAQ)

Q: Can the 1078683 directly replace the 2829564 in existing applications?

A: Direct replacement requires two conditions: the application load current must not exceed 6A, and the mounting interface must be adapted from socketable to DIN rail configuration. Electrical compatibility is established through matching SPST-NO contact form and 24VDC coil voltage.

Q: What is the impact of the reduced contact rating from 10A to 6A?

A: The 6A rating of the 1078683 establishes the maximum continuous current the relay contacts can safely switch. Applications operating above 6A require alternative parts with higher contact ratings.

Q: How do the termination differences affect installation?

A: The original 2829564 uses plug-in termination for socketable mounting. The 1078683 uses spring terminals for DIN rail mounting. Installation requires appropriate terminal blocks or DIN rail adapters compatible with spring terminal connections.

Q: Are there compliance differences between the two relays?

A: Both relays are RoHS compliant. The 1078683 carries ROHS3 compliance and is REACH affected, representing current regulatory alignment. The obsolete 2829564 meets legacy RoHS requirements.

Q: What operational advantages does the 1078683 provide?

A: The substitute offers extended operating temperature range (-40°C to 60°C vs. -20°C to 50°C), dual voltage switching capability (250VAC and 250VDC), reduced coil current consumption, and integrated lighted indicator for operational status monitoring.
