Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2834724 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Coil voltage: 24VDC (mandatory match)
• Contact form: 4PDT (4 Form C) configuration (mandatory match)
• Mounting type: DIN Rail (mandatory match)
• Termination style: Screw Terminal (mandatory match)
• Coil type: Non Latching (mandatory match)

Secondary Compatibility Criteria:

• Contact rating current: Equal to or greater than 5A
• Switching voltage: Equal to or greater than 250VAC and 125VDC
• Operating temperature range: Must encompass or exceed -25°C ~ 60°C
• Features: Diode and socket inclusion preferred for direct replacement
• RoHS and REACH compliance: ROHS3 Compliant and REACH Unaffected

The Phoenix Contact 2903320 meets all primary and secondary compatibility criteria, with enhanced specifications in contact rating (6A vs 5A) and switching voltage capability (250VDC vs 125VDC maximum).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903320 is the direct substitute for the obsolete 2834724. Both components maintain identical coil voltage (24VDC), contact configuration (4PDT), mounting platform (DIN Rail), and termination method (Screw Terminal). The 2903320 provides enhanced electrical performance with increased contact rating (6A vs 5A) and extended DC switching voltage capability (250VDC vs 125VDC maximum), while maintaining backward compatibility with existing socket and installation infrastructure.

The 2903320 holds active product status with full ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment. The extended operating temperature range (-40°C to 60°C vs -25°C to 60°C) provides additional environmental margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the 2903320 directly replace the 2834724 in existing installations?

A: Yes. Both relays share identical coil voltage (24VDC), contact configuration (4PDT), DIN rail mounting, screw terminal termination, and socket compatibility. The 2903320 provides equal or superior electrical performance across all specified parameters.

Q: What are the key differences between these two relays?

A: The 2903320 offers higher contact current rating (6A vs 5A), extended DC switching voltage (250VDC vs 125VDC), lower operating temperature limit (-40°C vs -25°C), and active product status versus obsolete status. Coil current increases from 38mA to 42mA.

Q: Are there any compatibility concerns with the increased coil current in the 2903320?

A: The coil current increase from 38mA to 42mA is within normal design tolerance for 24VDC control circuits. Existing power supply and control circuitry designed for the 2834724 will accommodate this specification without modification.

Q: Does the 2903320 maintain the same packaging and socket compatibility?

A: Yes. Both relays include socket mounting capability and screw terminal connections. The 2903320 is supplied in bulk packaging, consistent with standard DIN rail relay distribution formats.

Q: What is the significance of the extended temperature range in the 2903320?

A: The 2903320 operates from -40°C to 60°C compared to -25°C to 60°C for the 2834724. This extended lower temperature limit provides additional operational margin for applications in cold environments or equipment with limited thermal management.
