Phoenix Contact 2964526 General Purpose Relay SPDT 6A 48V - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2964526 is a general purpose relay with Single Pole Double Throw (SPDT) contact configuration, rated for 6A at 48VAC/DC coil voltage. This relay is designed for DIN rail mounting and includes a lighted indicator with socket. The part is currently obsolete, making identification of suitable substitute components essential for system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2964526 is determined by the following critical parameters:

• Contact Configuration: SPDT (1 Form C) contact form must be maintained
• Current Rating: 6A contact rating is required
• Coil Voltage: 48V operation (AC or DC acceptable)
• Switching Voltage: Maximum 250VAC/250VDC capability
• Mounting: DIN rail mounting required
• Coil Type: Non-latching operation
• Regulatory Compliance: RoHS compliance required

The Phoenix Contact 2900301 meets these substitution criteria while offering improved performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900301 is a direct functional substitute for the obsolete 2964526. Both relays maintain identical contact configuration (SPDT), current rating (6A), and maximum switching voltage (250VAC/250VDC). The 2900301 is actively manufactured and carries ROHS3 compliance, providing superior regulatory standing compared to the obsolete main part.

Key differences in the 2900301 include faster switching response (5ms operate, 8ms release versus 7ms/11ms), extended operating temperature range (-40°C to 60°C versus -20°C to 40°C), and spring terminal termination instead of screw terminal. The coil voltage specification differs slightly: the 2900301 is rated for 48VDC only, whereas the 2964526 accepts both 48VAC and 48VDC. Applications requiring AC coil operation must verify compatibility with the 48VDC-only specification of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900301 directly replace the 2964526 in all applications?

A: The 2900301 provides functional equivalence for SPDT relay operations at 6A and 48V. However, the main part accepts 48VAC/DC while the substitute is rated for 48VDC only. Applications using 48VAC coil voltage require verification that 48VDC operation is acceptable for the system design.

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

A: The 2964526 uses screw terminal connections requiring manual wire insertion and screw tightening. The 2900301 uses spring terminal connections that accept wire insertion without additional fastening. Spring terminals typically provide faster installation but require compatible wire gauges.

Q: Does the faster switching time of the 2900301 affect compatibility?

A: The 2900301 operates faster (5ms operate, 8ms release) compared to the 2964526 (7ms operate, 11ms release). For most general purpose relay applications, faster switching is beneficial. Applications with timing-critical requirements should verify that the faster response does not conflict with system logic or control sequences.

Q: Are both relays RoHS compliant?

A: Yes. The 2964526 is RoHS Compliant. The 2900301 carries ROHS3 Compliant certification, representing current regulatory standards. Both meet RoHS requirements for hazardous substance restrictions.

Q: What is the temperature operating range difference?

A: The 2964526 operates from -20°C to 40°C. The 2900301 extends this range to -40°C to 60°C, providing greater thermal tolerance for industrial environments with wider temperature fluctuations.
