Phoenix Contact 2964034 General Purpose Relay SPST-NO 12VDC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2964034 is a general purpose relay with SPST-NO (1 Form A) contact configuration, rated for 6A at 12VDC coil voltage. This relay is designed for DIN rail mounting with screw terminal connections and includes integrated diode protection and lighted indicator features. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2964034 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 12VDC (non-negotiable for direct circuit compatibility)
• Contact form: SPST-NO (1 Form A) configuration
• Contact current rating: 6A minimum
• Switching voltage capability: 250VAC, 250VDC minimum
• Mounting type: DIN rail
• Coil type: Non-latching operation
• Presence of integrated diode protection

The Phoenix Contact 2903362 meets all substitution criteria. While it operates from the RIF series (versus the obsolete EMG 10-REL series), it maintains functional equivalence across all critical electrical and mechanical parameters. Differences in coil current (16 mA versus 38 mA), termination style (spring terminal versus screw terminal), and operating temperature range represent design improvements in the substitute part but do not prevent direct functional replacement in applications designed for the original 2964034.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903362 is the direct functional substitute for the obsolete 2964034. Both relays are manufactured by Phoenix Contact and maintain identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage capability.

Selection of the 2903362 is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance exceeds the RoHS compliance of the original part, meeting current regulatory requirements
• Improved operating temperature range (-40°C to 60°C versus -20°C to 40°C) provides enhanced environmental tolerance
• Reduced coil current (16 mA versus 38 mA) decreases power consumption in control circuits
• Faster switching times (5 ms operate, 8 ms release versus 7 ms and 11 ms) improve system response characteristics
• Spring terminal design offers simplified installation compared to screw terminal configuration

The substitute part maintains all critical functional parameters required for direct replacement in applications originally designed for the 2964034.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903362 directly replace the 2964034 in existing installations?

A: Yes. Both relays share identical coil voltage (12VDC), contact configuration (SPST-NO), current rating (6A), and switching voltage capability (250VAC/250VDC). The 2903362 is functionally equivalent and suitable for direct substitution.

Q: What is the difference between screw terminal and spring terminal connections?

A: The 2964034 uses screw terminals requiring manual tightening of connection screws. The 2903362 uses spring terminals that accept wire insertion without additional fastening. Spring terminals simplify installation and reduce connection time but require compatible wire gauges.

Q: Does the lower coil current of the 2903362 affect circuit design?

A: No. The 2903362 coil current of 16 mA is lower than the 2964034 specification of 38 mA. This represents improved efficiency and reduces power consumption in the control circuit. Existing control circuits designed for the 2964034 will operate the 2903362 without modification.

Q: Are there temperature range considerations for substitution?

A: The 2903362 operates across -40°C to 60°C, compared to the 2964034 range of -20°C to 40°C. The substitute part provides extended environmental tolerance. If the original application operates within -20°C to 40°C, the 2903362 is fully compatible. Applications requiring operation below -20°C or above 40°C benefit from the expanded range of the substitute part.

Q: What is the significance of the different contact materials?

A: The 2964034 uses Silver Nickel (AgNi) contacts; the 2903362 uses Silver Tin Oxide (AgSnO) contacts. Both materials are standard for general purpose relay applications. The AgSnO material in the 2903362 provides enhanced resistance to contact wear and oxidation, supporting extended service life.

Q: Does the inclusion of a socket in the 2903362 affect compatibility?

A: The 2903362 includes an optional socket for relay mounting. This feature does not affect electrical compatibility. The relay functions identically whether mounted directly to DIN rail or installed via the included socket.
