Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2903680 qualifies as a direct substitute for the 2834119 based on the following critical parameters:

Matching Parameters:

• Coil voltage: 110VDC (identical)
• Contact form: 4PDT (4 Form C) (identical)
• Mounting type: Socketable (identical)
• Termination style: Plug In (identical)
• Coil type: Non Latching (identical)
• Contact material: Silver Nickel (AgNi) (identical)
• Switching voltage: 250VAC, 250VDC - Max (identical)
• RoHS compliance: Yes (both compliant)

Allowable Variations:

• Contact rating: 6A (substitute) vs 5A (original) — higher rating is acceptable for backward compatibility
• Coil current: 8mA (substitute) vs 10mA (original) — lower current consumption is acceptable
• Operating temperature: -40°C ~ 70°C (substitute) vs -55°C ~ 70°C (original) — narrower range acceptable for most applications
• Operate/Release times: Minor variations within industrial tolerance

The 2903680 is classified as an active product with enhanced features including integrated diode, lighted indicator, and test button, providing superior functionality while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 2903680 is the recommended substitute for the obsolete 2834119. Both relays maintain identical electrical specifications for coil voltage, contact configuration, and switching ratings, ensuring direct functional compatibility in existing circuits.

The 2903680 offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The higher contact rating (6A vs 5A) provides additional margin for applications operating near the 5A threshold. The lower coil current (8mA vs 10mA) reduces power consumption in the control circuit.

The narrower operating temperature range (-40°C to 70°C vs -55°C to 70°C) is acceptable for standard industrial environments. Applications requiring operation below -40°C should retain the original 2834119 if available from inventory or seek alternative solutions.

Both parts carry RoHS compliance certification and are suitable for regulated applications. The 2903680 includes integrated diode protection, lighted indicator, and test button features, providing enhanced diagnostics and protection without requiring external components.

Frequently Asked Questions (FAQ)

Q: Can the 2903680 directly replace the 2834119 in existing circuits?

A: Yes. Both relays share identical coil voltage (110VDC), contact configuration (4PDT), mounting type (socketable), and termination style (plug-in). The 2903680 has a higher contact rating (6A vs 5A), which is acceptable for backward compatibility. Socket compatibility is maintained.

Q: What is the impact of the 6A vs 5A contact rating difference?

A: The 2903680's 6A rating provides additional current-carrying capacity. Circuits designed for 5A operation will function within the 2903680's specifications. No circuit modifications are required.

Q: Does the operating temperature range difference affect substitution?

A: The 2903680 operates from -40°C to 70°C, compared to the 2834119's -55°C to 70°C. For applications within the -40°C to 70°C range, substitution is direct. Applications requiring operation below -40°C require evaluation of alternative solutions.

Q: Are there packaging differences between these parts?

A: The 2834119 is packaged as individual units, while the 2903680 is supplied in bulk packaging. Both use identical socketable plug-in termination. Bulk packaging does not affect electrical or mechanical compatibility.

Q: What additional features does the 2903680 provide?

A: The 2903680 includes integrated diode protection, a lighted indicator for coil status, and a test button for manual operation verification. These features enhance circuit diagnostics and protection without requiring external components.

Q: Are both relays RoHS compliant?

A: Yes. Both the 2834119 and 2903680 are RoHS compliant, meeting regulatory requirements for restricted substances in electrical and electronic equipment.
