Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2903350 qualifies as a direct substitute for the 2834481 based on the following critical parameters:

• Coil Voltage: Both parts operate at 24VDC
• Contact Configuration: Both feature DPDT (2 Form C) contact form
• Current Rating: Both rated for 8A continuous contact current
• Switching Voltage: Both support 250VAC and 250VDC maximum switching voltage
• Mounting and Termination: Both use DIN rail mounting with screw terminal connections
• Integrated Features: Both include diode, lighted indicator, and socket
• Contact Material: Both use Silver Nickel (AgNi) contacts
• Coil Type: Both are non-latching relays

The 2903350 represents an active product from the RIF series, providing functional and electrical equivalence to the obsolete PR1 series 2834481.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903350 is the appropriate selection for applications currently using or specifying the obsolete 2834481. The 2903350 maintains electrical and mechanical equivalence across all critical parameters while offering the advantage of active product status and extended availability.

The 2903350 provides an expanded operating temperature range (-40°C to 70°C versus -25°C to 60°C), which accommodates a broader range of environmental conditions. The coil current is marginally lower (18 mA versus 19 mA), representing improved efficiency without functional impact. Both parts maintain ROHS3 compliance and EAR99 classification.

For new designs or system replacements, the 2903350 should be specified to ensure long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 2903350 directly replace the 2834481 in existing installations?

A: Yes. The 2903350 provides direct functional and electrical equivalence. Both relays feature identical coil voltage (24VDC), contact configuration (DPDT), current rating (8A), switching voltage (250VAC/250VDC), mounting type (DIN rail), and termination style (screw terminal). Socket compatibility and integrated features (diode, lighted indicator) are identical.

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

A: The primary differences are product status and operating temperature range. The 2834481 is obsolete; the 2903350 is active. The 2903350 operates across -40°C to 70°C compared to the 2834481's -25°C to 60°C range. Coil current is slightly lower in the 2903350 (18 mA versus 19 mA). These differences do not affect substitution suitability for standard applications.

Q: Are there packaging differences between these parts?

A: The 2834481 is supplied with standard packaging; the 2903350 is supplied in bulk packaging. Both are suitable for DIN rail installation and screw terminal connection. Packaging format does not affect electrical or mechanical performance.

Q: Do both relays meet the same compliance standards?

A: Yes. Both the 2834481 and 2903350 are ROHS3 compliant and classified as EAR99 for export control purposes. The 2903350 is REACH affected, while the 2834481 is REACH unaffected; however, this does not impact functional substitution.

Q: Which relay should be specified for new designs?

A: The 2903350 should be specified for new designs. As an active product with extended temperature range and improved coil efficiency, it provides superior long-term availability and performance characteristics compared to the obsolete 2834481.
