Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834504 is determined by the following critical parameters:

• Coil Voltage: 120VAC (exact match required)
• Contact Form: DPDT (2 Form C) (exact match required)
• Contact Rating: 8 A minimum (exact match required)
• Switching Voltage: 250VAC, 250VDC maximum (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Termination Style: Screw Terminal (exact match required)
• Coil Type: Non Latching (exact match required)

The Phoenix Contact 2903348 meets all critical substitution criteria. This part maintains identical electrical specifications for coil voltage, contact configuration, current rating, and switching voltage. Both relays feature DIN rail mounting with screw terminals and non-latching coil operation. The 2903348 is classified as an active product, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903348 is the direct substitute for the obsolete 2834504. Both relays satisfy identical electrical and mechanical requirements for DPDT 8A 120VAC general purpose relay applications with DIN rail mounting.

The 2903348 offers the advantage of active product status, ensuring long-term availability and manufacturing support. This part carries ROHS3 compliance certification and is REACH affected, meeting current regulatory requirements for electronic component procurement.

Minor operational differences exist in release time (20 ms versus 16 ms) and operating temperature range (-40°C ~ 50°C versus -25°C ~ 60°C). These variations remain within acceptable tolerances for general purpose relay applications and do not affect functional compatibility in standard switching circuits.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903348 directly replace the 2834504 in existing installations?

A: Yes. Both relays share identical coil voltage (120VAC), contact configuration (DPDT), current rating (8A), switching voltage (250VAC/250VDC), mounting type (DIN rail), and termination style (screw terminal). Electrical and mechanical compatibility is confirmed.

Q: What is the significance of the product status difference?

A: The 2834504 is classified as obsolete, indicating discontinued manufacturing and limited future availability. The 2903348 is an active product with ongoing production and supply chain support, making it the preferred choice for new designs and long-term system maintenance.

Q: Are there compliance differences between these parts?

A: The 2834504 carries RoHS Compliant certification. The 2903348 carries ROHS3 Compliant certification and is REACH affected. Both meet current regulatory standards for electronic components. The 2903348 reflects more recent compliance frameworks.

Q: How do the timing specifications differ?

A: The 2834504 operates with 12 ms operate time and 16 ms release time. The 2903348 maintains the same 12 ms operate time but has a 20 ms release time. This 4 ms difference in release time does not affect compatibility in general purpose switching applications.

Q: What is the operating temperature range difference?

A: The 2834504 operates from -25°C to 60°C. The 2903348 operates from -40°C to 50°C. The 2903348 provides extended low-temperature capability but a slightly reduced upper temperature limit. Selection depends on specific environmental requirements.

Q: Are packaging considerations relevant for substitution?

A: The 2834504 is packaged as individual units. The 2903348 is supplied in bulk packaging. Both are compatible for DIN rail installation. Bulk packaging may offer cost advantages for larger procurement volumes.
