Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2834106 is determined by the following critical parameters:

• Contact Configuration: 4PDT (4 Form C) contact form
• Coil Voltage: 48VDC operation
• Mounting Interface: Socketable plug-in design
• Coil Type: Non-latching operation
• Switching Capability: 250VAC/250VDC maximum voltage rating

The Phoenix Contact 2903671 qualifies as a substitute based on matching contact form, coil voltage, mounting type, and coil operation. The 2903671 maintains electrical compatibility while offering enhanced features and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903671 is the qualified substitute for the obsolete 2834106 based on matching core electrical and mechanical specifications. The 2903671 offers the following advantages:

• Active Product Status: Currently manufactured and supported by Phoenix Contact, ensuring long-term availability
• Enhanced Compliance: ROHS3 Compliant with REACH Unaffected status, meeting current regulatory requirements
• Increased Current Rating: 6A contact rating provides margin above the original 5A specification
• Additional Features: Integrated diode, lighted indicator, mechanical indicator, and test button for enhanced diagnostics

The 2903671 maintains backward compatibility with existing socketable mounting interfaces and plug-in termination. The higher coil current (22 mA vs. 19 mA) and lower coil resistance (2.2 kOhms vs. 2.56 kOhms) are within acceptable operating parameters for 48VDC control circuits.

Frequently Asked Questions (FAQ)

Q: Can the 2903671 directly replace the 2834106 in existing applications?

A: Yes. Both relays share identical contact form (4PDT), coil voltage (48VDC), mounting type (socketable), and termination style (plug-in). The 2903671's higher current rating (6A vs. 5A) and enhanced contact material (AgNi/Au vs. AgNi) provide equivalent or superior performance in the same socket.

Q: What is the difference in operating temperature range?

A: The 2834106 operates from -55°C to 70°C, while the 2903671 operates from -40°C to 70°C. For applications requiring operation below -40°C, the original 2834106 specification must be maintained. For standard industrial temperature ranges, the 2903671 is suitable.

Q: Are there differences in switching speed?

A: Operate time is identical at 13 ms. Release time differs: 2834106 releases in 5 ms while 2903671 releases in 14 ms. For time-critical switching applications, this 9 ms difference must be evaluated against system requirements.

Q: What packaging is available for the 2903671?

A: The 2903671 is supplied in bulk packaging, compared to the original part's standard packaging designation. Confirm packaging requirements with procurement specifications.

Q: Are both parts RoHS compliant?

A: Yes. The 2834106 is RoHS Compliant. The 2903671 is ROHS3 Compliant, meeting current and future regulatory standards. Both parts are suitable for RoHS-regulated applications.
