Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2907054 qualifies as a direct substitute for the 2834203 based on the following critical parameters:

Matching Parameters:

• Coil voltage: 24VDC (identical)
• Contact form: 4PDT (4 Form C) (identical)
• Coil current: 38 mA (identical)
• Coil type: Non Latching (identical)
• Mounting type: Socketable (identical)
• Termination style: Plug In (identical)
• Contact material: Silver Nickel (AgNi) (identical)
• Switching voltage: 250VAC, 250VDC - Max (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Allowable Variation:

• Contact rating: 2907054 provides 6A versus 2834203's 5A (higher rating is acceptable for backward compatibility)
• Operating temperature: 2907054 operates -40°C ~ 70°C versus 2834203's -55°C ~ 70°C (narrower range acceptable for most applications)
• Response times: 2907054 has 13ms operate time and 3ms release time versus 2834203's 13ms operate and 5ms release time (within acceptable switching performance parameters)

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907054 is the direct substitute for the obsolete 2834203. The 2907054 is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain identical ROHS3 and REACH compliance certifications, satisfying regulatory requirements for equivalent component selection.

The 2907054 provides enhanced contact current rating (6A versus 5A), which offers improved margin for applications originally designed for the 2834203's 5A specification. The operating temperature range of the 2907054 (-40°C ~ 70°C) is suitable for standard industrial applications; systems requiring operation below -40°C must evaluate the narrower temperature specification against specific application requirements.

Both relays share identical coil voltage, contact form, coil current, and termination characteristics, ensuring direct functional equivalence in socketable relay base installations. The 2907054 includes mechanical indicator and test button features not present in the 2834203, providing additional operational diagnostics without affecting electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2907054 directly replace the 2834203 in existing installations?

A: Yes. Both relays are socketable with identical plug-in termination, coil voltage (24VDC), contact form (4PDT), and coil current (38 mA). The 2907054 can be inserted into existing relay bases designed for the 2834203 without modification.

Q: What is the significance of the higher 6A contact rating on the 2907054?

A: The 2907054's 6A rating provides backward compatibility with the 2834203's 5A specification. Applications switching 5A loads operate within the 2907054's rated capacity with additional safety margin. No derating is required.

Q: Are there temperature limitations when substituting the 2907054 for the 2834203?

A: The 2907054 operates from -40°C to 70°C, compared to the 2834203's -55°C to 70°C range. For applications requiring operation below -40°C, the narrower temperature specification must be evaluated against system requirements. Standard industrial temperature ranges are fully supported.

Q: Do the relays have identical switching performance?

A: Both relays operate at 13ms with coil energization. Release time differs slightly: 2834203 releases in 5ms while 2907054 releases in 3ms. The faster release time of the 2907054 is advantageous for applications requiring rapid contact opening.

Q: What compliance certifications apply to both relays?

A: Both the 2834203 and 2907054 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component distribution and use.

Q: Does the 2907054's mechanical indicator affect electrical operation?

A: No. The mechanical indicator and test button are auxiliary features that do not alter the electrical switching characteristics or performance of the relay contacts.
