Key Parameters

Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 2829470 is based on the following critical parameters:

• Coil Voltage: 120VAC/DC (primary control signal requirement)
• Contact Rating: 50 mA (load switching capacity)
• Switching Voltage: 30VAC/30VDC maximum (signal level compatibility)
• Coil Current: Approximately 5 mA (power consumption profile)
• Contact Form: DPST-NO or equivalent switching topology
• Compliance: RoHS Compliant status
• Manufacturer: Phoenix Contact (product line continuity)

The substitute part Phoenix Contact 2900342 shares the same coil voltage (120VAC/DC), identical contact current rating (50 mA), compatible switching voltage specification, and RoHS compliance. While the contact form differs (DPDT vs. DPST-NO), the electrical parameters and control characteristics remain functionally aligned for general purpose relay applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900342 is an active product suitable for applications requiring replacement of the obsolete 2829470. Both relays maintain identical coil voltage (120VAC/DC) and contact current rating (50 mA), ensuring compatibility in control circuits and load switching scenarios.

Key considerations for selection:

• Product Status: The 2900342 is active and currently in production, providing long-term availability and supply chain stability compared to the obsolete 2829470.
• RoHS Compliance: Both parts maintain RoHS Compliant status, meeting environmental and regulatory requirements.
• Contact Form Difference: The 2900342 provides DPDT (2 Form C) configuration versus the DPST-NO (2 Form A) of the original part. Applications requiring only single-pole switching must account for the additional contact set.
• Mounting and Termination: The 2900342 uses DIN Rail mounting with screw terminals, differing from the socketable plug-in design of the 2829470. Installation methodology and panel layout must be adapted accordingly.
• Operating Temperature Range: The 2900342 extends the operating range to -40°C ~ 60°C, providing broader environmental tolerance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900342 directly replace the 2829470 in existing applications?

A: Direct replacement requires evaluation of mounting type and termination style. The 2829470 uses socketable plug-in termination, while the 2900342 requires DIN Rail mounting with screw terminals. Circuit functionality is compatible due to matching coil voltage (120VAC/DC) and contact current rating (50 mA), but physical installation differs.

Q: What is the primary difference between DPST-NO and DPDT contact forms?

A: DPST-NO (Double Pole Single Throw - Normally Open) provides two independent normally-open contacts. DPDT (Double Pole Double Throw) provides two contacts, each with both normally-open and normally-closed positions. Applications using only the normally-open function can utilize the DPDT configuration by ignoring the normally-closed contacts.

Q: Are both relays RoHS compliant?

A: Yes. Both the 2829470 and 2900342 are RoHS Compliant, meeting environmental and regulatory standards for electronic components.

Q: What is the coil current difference between these parts?

A: The 2829470 draws 5 mA coil current, while the 2900342 draws 4.5 mA. This 0.5 mA reduction in the substitute part represents improved efficiency with negligible impact on control circuit design.

Q: Does the 2900342 support the same switching voltage as the 2829470?

A: Both parts support 30VAC switching voltage. The 2900342 extends DC switching capability to 36VDC compared to 30VDC for the 2829470, providing enhanced compatibility with higher DC signal levels.

Q: What packaging is available for the 2900342?

A: The 2900342 is supplied in Bulk packaging, differing from the standard packaging designation of the 2829470.
