Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834973 is determined by the following critical parameters:

• Contact Configuration: 4PDT (4 Form C) contact form is mandatory for equivalent switching capability
• Coil Voltage: 220VDC coil voltage must be maintained for direct circuit compatibility
• Mounting Type: Socketable mounting ensures mechanical and electrical compatibility with existing relay bases
• Termination Style: Plug In termination is required for socket compatibility
• Contact Rating: Minimum 5 A current rating at 250VAC/250VDC switching voltage
• Coil Type: Non Latching operation for standard control applications
• RoHS Compliance: Required for regulatory compliance in modern applications

The substitute part Phoenix Contact 2903682 meets these critical substitution criteria while offering enhanced specifications in contact current rating and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903682 is the direct substitute for the obsolete 2834973. Both relays maintain identical contact configuration (4PDT), coil voltage (220VDC), mounting type (socketable), and termination style (plug in). The 2903682 provides enhanced contact current rating (6 A versus 5 A), making it suitable for applications requiring the original 5 A specification with additional margin.

The 2903682 is an active product with current manufacturing support and full RoHS compliance certification. The narrower operating temperature range (-40°C to 70°C versus -55°C to 70°C) should be evaluated for applications requiring extended low-temperature operation below -40°C.

Both relays feature identical switching voltage ratings (250VAC/250VDC maximum) and response times (13 ms operate, 14 ms release), ensuring functional equivalence in control circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903682 directly replace the 2834973 in existing installations?

A: Yes. Both relays share identical contact configuration (4PDT), coil voltage (220VDC), socketable mounting, and plug-in termination. The 2903682 can be inserted into existing relay sockets without modification.

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

A: The 2834973 is rated for 5 A contact current, while the 2903682 is rated for 6 A. Applications designed for 5 A operation will function within specification using the 2903682.

Q: Are there temperature range limitations when substituting the 2903682?

A: The 2903682 operating range is -40°C to 70°C, compared to -55°C to 70°C for the 2834973. Applications requiring operation below -40°C must retain the original 2834973 or identify alternative solutions.

Q: Do both relays meet current RoHS compliance requirements?

A: Yes. Both the 2834973 and 2903682 are RoHS compliant and suitable for applications with RoHS regulatory requirements.

Q: What is the coil current difference between these relays?

A: The 2834973 requires 3.6 mA coil current, while the 2903682 requires 4 mA. This 0.4 mA difference is negligible in most control circuit designs and does not affect circuit compatibility.

Q: Are the switching voltage ratings identical?

A: Yes. Both relays are rated for 250VAC and 250VDC maximum switching voltage, ensuring equivalent performance in AC and DC switching applications.
