Phoenix Contact 2834685 General Purpose Relay DPDT 10A 24V - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834685 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 24VDC coil voltage. This relay is designed for DIN rail mounting with spring terminal connections and includes integrated diode and lighted indicator features. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2903315 qualifies as a direct substitute for the 2834685 based on the following critical parameters:

Matching Parameters:

• Contact form: DPDT (2 Form C)
• Contact rating: 10 A
• Coil voltage: 24VDC
• Coil type: Non Latching
• Mounting type: DIN Rail
• Termination style: Spring Terminal
• Features: Diode, Lighted Indicator, Socket Included
• Contact material: Silver-based (Ag / AgNi)

Substitution Basis: The 2903315 maintains electrical and mechanical compatibility with the 2834685 across all primary functional parameters. Both relays operate on identical coil voltage, support the same contact configuration and current rating, and utilize compatible DIN rail mounting with spring terminals. The contact material composition (Silver Nickel vs. Silver) and minor timing differences (Release Time: 14 ms vs. 5 ms) remain within acceptable operational tolerances for general purpose relay applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903315 is the appropriate substitute for the obsolete 2834685. The 2903315 maintains active product status with current manufacturing support and ROHS3 compliance, providing superior regulatory alignment compared to the RoHS Compliant designation of the original part. The extended operating temperature range (-40°C to 60°C versus -25°C to 60°C) offers broader environmental compatibility. The 2903315 supports both 250VAC and 250VDC switching voltages, expanding application flexibility beyond the 250VAC maximum of the 2834685. Coil current differential (41 mA versus 38 mA) and release time variance (14 ms versus 5 ms) remain within acceptable engineering tolerances for general purpose relay circuits. Both parts carry MSL 1 rating and maintain identical contact configuration, current rating, and mounting architecture.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903315 directly replace the 2834685 in existing installations?

A: Yes. Both relays share identical DPDT contact configuration, 10A current rating, 24VDC coil voltage, DIN rail mounting, and spring terminal termination. Electrical and mechanical interfaces are compatible.

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

A: The 2903315 features extended operating temperature range (-40°C to 60°C), dual voltage switching capability (250VAC and 250VDC), Silver Nickel contact material versus Silver, and active product status with ROHS3 compliance. Release time is 14 ms compared to 5 ms on the 2834685.

Q: Does the 3 mA increase in coil current (41 mA vs. 38 mA) affect circuit design?

A: No. The 3 mA difference is negligible for general purpose relay applications and does not require circuit redesign or power supply recalculation.

Q: Is the 2903315 available in the same packaging as the 2834685?

A: The 2834685 was supplied with standard packaging. The 2903315 is available in bulk packaging. Both are DIN rail mount relays with identical form factors and mounting specifications.

Q: Why is the 2834685 listed as obsolete?

A: The 2834685 has been discontinued by Phoenix Contact. The 2903315 represents the current active equivalent within the Phoenix Contact product line.

Q: Are there any compliance differences between these parts?

A: The 2903315 carries ROHS3 compliance, representing current regulatory standards. The 2834685 carries RoHS Compliant designation. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
