Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834326 is determined by the following critical parameters:

• Coil Voltage: Must be 24VDC to maintain compatibility with existing control circuits
• Contact Form: Must be SPDT (1 Form C) to preserve switching functionality
• Mounting Type: Must be DIN Rail to ensure mechanical fit within existing enclosures
• Termination Style: Must be Screw Terminal for direct connection compatibility
• Contact Rating (Current): Substitute must meet or exceed 12A requirement
• Switching Voltage: Must support 250VAC and 250VDC maximum ratings
• Coil Type: Must be Non Latching to match operational behavior
• Features: Diode and Lighted Indicator presence ensures functional equivalence

The Phoenix Contact 2903358 satisfies all substitution criteria within the allowed parameter set.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903358 is the designated substitute for the obsolete 2834326. Both relays maintain identical electrical specifications for coil voltage, contact form, switching voltage, and termination style. The 2903358 is currently in active production status, ensuring long-term availability and supply chain continuity.

The 2903358 demonstrates enhanced compliance with ROHS3 standards and REACH regulations, providing improved environmental and regulatory alignment for new installations. The extended operating temperature range of -40°C to 70°C offers broader environmental applicability compared to the original part's -25°C to 60°C range.

The contact rating differential of 11A versus 12A on the substitute part requires evaluation within the specific application context. Applications requiring the full 12A contact rating must be assessed for compatibility with the 11A specification of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903358 directly replace the 2834326 in existing installations?

A: The 2903358 maintains functional equivalence across all critical parameters including coil voltage, contact form, mounting type, and termination style. The primary consideration is the contact rating reduction from 12A to 11A. Applications operating below 11A current levels support direct substitution without modification.

Q: What is the significance of the contact rating difference between these relays?

A: The 2834326 is rated for 12A continuous contact current, while the 2903358 is rated for 11A. This 1A difference represents the maximum continuous current the relay contacts can safely handle. Applications must operate within the 11A limit when using the substitute part.

Q: Are there packaging differences between these parts?

A: The 2834326 is supplied with standard packaging, while the 2903358 is supplied in bulk packaging. Both parts are identical in form factor and DIN rail mounting configuration. Packaging differences do not affect electrical or mechanical compatibility.

Q: Why is the 2903358 preferred over the obsolete 2834326?

A: The 2903358 is in active production status, ensuring availability for future procurement. The part also meets current ROHS3 and REACH compliance requirements, making it suitable for new designs and long-term system support.

Q: How do the operating temperature ranges compare?

A: The 2834326 operates from -25°C to 60°C, while the 2903358 operates from -40°C to 70°C. The substitute part provides a wider temperature envelope, supporting deployment in more demanding thermal environments.
