Phoenix Contact 2966553 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2966553 is a general purpose relay with SPDT (Single Pole Double Throw) contact configuration, rated for 6A at 24VAC/DC coil voltage. This component is classified as obsolete, making identification of suitable substitute parts essential for system maintenance and new design implementations. The relay features DIN rail mounting, spring terminal connections, and includes a lighted indicator with socket for enhanced operational visibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2966553 is determined by the following critical parameters:

• Mounting Type: DIN Rail compatibility is mandatory for form factor equivalence
• Coil Voltage: 24VAC/DC operation must be maintained for control circuit compatibility
• Contact Form: SPDT (1 Form C) configuration is required for circuit topology preservation
• Coil Type: Non-latching operation ensures functional equivalence in control applications
• Termination Style: Spring terminal connections must match for installation compatibility
• Operating Temperature Range: -40°C ~ 60°C operational envelope must be supported

The Phoenix Contact 2900307 qualifies as a direct substitute based on these parameters. However, the contact current rating differs significantly: the 2900307 is rated for 50 mA maximum, compared to the 6 A rating of the 2966553. This difference restricts substitution to applications where load current does not exceed 50 mA.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900307 is an active product with ROHS3 compliance, providing a path forward from the obsolete 2966553. Both components share identical coil voltage, contact form, timing characteristics, and operating temperature specifications.

Selection of the 2900307 as a substitute is appropriate when the application load current does not exceed 50 mA. The 2900307 also operates at reduced maximum switching voltages (30VAC, 36VDC) compared to the 2966553 (250VAC, 250VDC), which must be evaluated against the specific switching requirements of the target circuit.

The active product status of the 2900307 ensures continued availability and supply chain stability for new implementations and system replacements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900307 directly replace the 2966553 in all applications?

A: Direct substitution is limited by contact current rating. The 2900307 is rated for 50 mA maximum, while the 2966553 supports 6 A. Substitution is valid only when the application load current remains below 50 mA. Additionally, the maximum switching voltage of the 2900307 (30VAC, 36VDC) is lower than the 2966553 (250VAC, 250VDC), requiring circuit voltage verification.

Q: What are the key compatibility factors between these relays?

A: Both relays maintain identical DIN rail mounting, 24VAC/DC coil voltage, SPDT contact configuration, non-latching coil type, spring terminal termination, and operating temperature range. These parameters ensure mechanical and electrical interface compatibility.

Q: Why is the 2966553 obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The active status of the 2900307 indicates Phoenix Contact's current product direction for this relay category.

Q: Are there packaging differences between these parts?

A: The 2966553 is specified with "-" packaging notation, while the 2900307 is supplied in bulk packaging. Both components include socket and lighted indicator features.

Q: What compliance certifications apply to substitution?

A: The 2966553 carries RoHS compliance certification. The 2900307 meets ROHS3 compliance and is REACH affected. Both components are classified under ECCN EAR99. Compliance requirements of the target application must be evaluated against these certifications.
