Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834164 is determined by the following critical parameters:

• Coil Voltage: Must be 24VDC to maintain circuit compatibility
• Contact Form: Must be DPDT (2 Form C) for equivalent switching capability
• Mounting Type: Must be socketable to fit existing relay bases
• Termination Style: Must be plug-in compatible
• Contact Rating: Minimum 10A required; higher ratings are acceptable for applications within the specified switching voltage limits
• Coil Current: 38 mA specification ensures compatibility with existing drive circuits
• Coil Type: Non-latching operation required for standard control applications
• Operating Temperature Range: Must accommodate the application's thermal environment

The Phoenix Contact 2907051 meets all critical substitution criteria while offering enhanced current capacity and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907051 is a direct functional substitute for the 2834164. Both relays share identical coil voltage, contact form, mounting configuration, and termination style. The 2907051 provides a 2A increase in contact rating (12A versus 10A), which is compatible with all applications designed for the original 10A specification.

The 2907051 offers the advantage of active product status, ensuring continued availability and supply chain reliability. It meets ROHS3 compliance, exceeding the RoHS compliance of the original part. The operating temperature range of -40°C to 70°C covers most industrial applications; applications requiring the extended -55°C lower limit of the original part require thermal environment verification.

The contact material change from Silver (Ag) to Silver Nickel (AgNi) provides improved contact durability and arc resistance. The faster release time (3 ms versus 5 ms) may benefit applications requiring rapid de-energization.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907051 directly replace the 2834164 in existing installations?

A: Yes. Both relays are socketable with identical plug-in termination, coil voltage, contact form, and coil current specifications. The 2907051 can be inserted into existing relay bases designed for the 2834164.

Q: What is the significance of the higher 12A contact rating on the 2907051?

A: The 12A rating on the 2907051 provides additional margin for applications originally designed for 10A operation. This does not require circuit modification and ensures compatibility with the specified 250VAC and 250VDC maximum switching voltages.

Q: Does the operating temperature range difference affect substitution?

A: The 2907051 operates from -40°C to 70°C, compared to the 2834164's -55°C to 70°C range. For applications operating above -40°C, the 2907051 is fully suitable. Applications requiring operation below -40°C require thermal environment assessment.

Q: What is the difference between Silver (Ag) and Silver Nickel (AgNi) contact materials?

A: Silver Nickel contacts provide enhanced durability and improved arc resistance compared to pure silver contacts. This material change does not affect electrical compatibility and generally extends contact life in switching applications.

Q: Is the faster 3 ms release time of the 2907051 a concern?

A: No. The faster release time is a performance improvement that does not negatively impact compatibility. Applications designed for the 5 ms release time of the original part will function correctly with the faster response of the substitute.

Q: Are there packaging differences between these parts?

A: The 2834164 is listed with dash packaging notation, while the 2907051 is supplied in bulk packaging. Both are socketable relays with identical mechanical form factors.
