Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834795 is determined by the following critical parameters:

Coil Voltage: 230VAC (must match exactly)
Contact Form: 4PDT (4 Form C) configuration (must match exactly)
Contact Rating: 5A minimum (equal or higher acceptable)
Switching Voltage: 250VAC, 250VDC maximum (must meet or exceed)
Mounting Type: DIN Rail (must match)
Termination Style: Spring Terminal (must match)
Coil Type: Non Latching (must match)

The Phoenix Contact 2903304 satisfies all critical substitution criteria. Both relays share identical coil voltage, contact form, current rating, switching voltage capability, mounting configuration, and termination style. The 2903304 represents an active product from the RIF series, providing long-term availability and supply chain continuity.

Engineering Selection Recommendations

The Phoenix Contact 2903304 is the direct substitute for the obsolete 2834795. Selection is based on the following engineering criteria:

Product Status: The 2834795 is obsolete, while the 2903304 is active. This ensures continued availability and supply chain reliability for replacement and new installations.

Electrical Equivalence: Both relays maintain identical coil voltage (230VAC), contact configuration (4PDT), current rating (5A), and switching voltage limits (250VAC/250VDC). These parameters are critical for circuit compatibility.

Mechanical Compatibility: Both relays use DIN rail mounting with spring terminal connections, ensuring direct physical replacement without enclosure or wiring modifications.

Compliance: The 2903304 meets ROHS3 compliance, exceeding the RoHS compliance of the original part. Both components are classified as EAR99 for export control purposes.

Operational Differences: The 2903304 exhibits slightly higher coil current (6.5 mA vs. 4 mA) and longer switching times (15 ms operate, 20 ms release vs. 10 ms and 12 ms respectively). These differences are within acceptable engineering tolerances for general purpose relay applications and do not preclude substitution.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903304 directly replace the 2834795 in existing installations?

A: Yes. Both relays share identical coil voltage, contact configuration, current rating, mounting type, and termination style. Direct replacement is possible without circuit or mechanical modifications.

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

A: The primary differences are coil current (2903304 draws 6.5 mA vs. 4 mA for the 2834795) and switching response times (2903304 operates in 15 ms and releases in 20 ms vs. 10 ms and 12 ms for the 2834795). The 2903304 also operates across a wider temperature range (-40°C to 50°C vs. -25°C to 60°C).

Q: Are there any compliance or certification differences?

A: The 2903304 meets ROHS3 compliance, which is a more recent standard than the RoHS compliance of the 2834795. Both components are EAR99 classified. The 2903304 also carries REACH Unaffected status.

Q: Does the higher coil current of the 2903304 affect circuit design?

A: The increase from 4 mA to 6.5 mA is minimal and typically does not require circuit redesign. Verify that the coil drive circuit can supply the additional current without exceeding component ratings.

Q: What is the packaging difference between these parts?

A: The 2834795 is supplied with standard packaging, while the 2903304 is supplied in bulk packaging. This does not affect electrical or mechanical performance.

Q: Is the 2903304 suitable for applications requiring the full -25°C to 60°C temperature range of the original part?

A: The 2903304 operates from -40°C to 50°C. Applications requiring operation above 50°C or below -40°C should be evaluated against the specific temperature requirements of the system.
