Phoenix Contact 2834355 General Purpose Relay SPDT 230VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834355 is a general purpose relay with Single Pole Double Throw (SPDT) contact configuration, rated for 12A at 230VAC coil voltage. This relay is designed for DIN rail mounting and features a non-latching coil type with integrated lighted indicator and varistor protection.

The 2834355 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new installations where this relay specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834355 is determined by the following critical parameters:

• Coil voltage: 230VAC (must match exactly)
• Contact form: SPDT (1 Form C) configuration (must match exactly)
• Mounting type: DIN Rail (must match exactly)
• Contact rating: Minimum 12A (substitute must meet or exceed)
• Switching voltage: 250VAC, 250VDC maximum (must meet or exceed)
• Termination style: Screw Terminal (must match exactly)
• Coil type: Non Latching (must match exactly)

The substitute part 2903355 meets these critical substitution criteria. While it has a lower contact rating (10A versus 12A), this represents a design trade-off in the active product line. The substitute maintains identical coil voltage, contact form, mounting type, termination style, and coil type.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903355 is the designated substitute for the obsolete 2834355. The 2903355 is an active product with current manufacturing status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

The primary design difference is the contact rating: the 2903355 is rated for 10A versus the 2834355's 12A rating. This substitution is appropriate for applications where the load current does not exceed 10A. For applications requiring the full 12A contact rating, alternative relay models outside this substitution group must be evaluated.

Both relays share identical coil voltage (230VAC), contact form (SPDT), mounting configuration (DIN Rail), and termination style (Screw Terminal). The 2903355 includes an integrated socket, which provides additional mounting flexibility compared to the base 2834355 configuration.

Frequently Asked Questions (FAQ)

Q: Can the 2903355 directly replace the 2834355 in all applications?

A: The 2903355 is a direct substitute for applications where the contact current does not exceed 10A. If your application requires the full 12A contact rating of the original 2834355, the 2903355 is not suitable. Verify your actual load current before substitution.

Q: What is the difference in operating temperature range between these relays?

A: The 2834355 operates from -25°C to 60°C, while the 2903355 operates from -40°C to 50°C. The 2903355 has a lower maximum temperature but extends the minimum temperature range. Confirm your application's temperature requirements before substitution.

Q: Are both relays compatible with the same DIN rail mounting hardware?

A: Yes. Both relays use DIN Rail mounting and Screw Terminal termination. The 2903355 includes an integrated socket, which may provide additional installation options.

Q: What is the significance of the ROHS3 compliance on the 2903355?

A: ROHS3 compliance indicates the 2903355 meets current regulatory requirements for hazardous substance restrictions. The obsolete 2834355 carries RoHS Compliant status. For new installations and long-term system support, the ROHS3-compliant 2903355 is the appropriate choice.

Q: How do the coil resistance values differ, and does this affect substitution?

A: The 2834355 has 41.82 kOhms coil resistance versus 38.33 kOhms for the 2903355. Both are designed for 230VAC coil voltage operation. The slight resistance difference reflects different coil winding designs but does not prevent direct substitution in standard 230VAC control circuits.

Q: What is the practical difference between the 12 ms operate time and 22 ms release time specifications?

A: Both relays share identical 12 ms operate time. The 2834355 has a 22 ms release time while the 2903355 has a 20 ms release time. These timing differences are negligible for most general-purpose relay applications and do not affect substitution suitability.
