Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2903664 qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (Phoenix Contact) and series (REL-IR)
• Matching contact form (DPDT / 2 Form C)
• Identical coil voltage (125VDC)
• Identical mounting type (Socketable) and termination style (Plug In)
• Identical coil type (Non Latching)
• Identical switching voltage rating (250VAC, 250VDC - Max)
• Identical operate and release times (13 ms / 14 ms)
• Compatible operating temperature range (-40°C ~ 70°C vs. -55°C ~ 70°C)

The 2903664 provides enhanced current rating (12A vs. 10A) and updated contact material (Silver Nickel vs. Silver), representing a direct upgrade path from the obsolete 2834960.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903664 is the direct substitute for the obsolete 2834960. Selection is based on:

• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance meeting current regulatory requirements versus RoHS compliance of the obsolete part
• Identical electrical and mechanical interface characteristics enabling direct socket replacement
• Enhanced current rating (12A) providing margin above the original 10A specification
• Improved contact material composition (Silver Nickel) offering enhanced durability and contact reliability

The substitute part maintains full functional and physical compatibility with existing socket installations designed for the 2834960.

Frequently Asked Questions (FAQ)

Q: Can the 2903664 directly replace the 2834960 in existing installations?

A: Yes. Both relays share identical socketable mounting, plug-in termination, DPDT contact configuration, 125VDC coil voltage, and switching voltage ratings. Direct socket replacement is supported without modification.

Q: What is the significance of the higher current rating (12A vs. 10A) on the substitute?

A: The 2903664 provides 20% additional current capacity. This represents an upgrade path suitable for applications requiring the original 10A rating or lower. No derating is required for circuits designed around the 2834960 specification.

Q: Are there differences in coil characteristics between the two parts?

A: Minor differences exist: coil current increases from 7.2 mA to 7.7 mA, and coil resistance decreases from 17.36 kOhms to 16.2 kOhms. These variations are within normal manufacturing tolerance ranges for equivalent relay designs and do not affect circuit compatibility.

Q: What is the operating temperature difference between these parts?

A: The 2834960 operates from -55°C to 70°C, while the 2903664 operates from -40°C to 70°C. For applications requiring operation below -40°C, the original part specification must be maintained. For standard industrial temperature ranges, the substitute is fully compatible.

Q: How do the contact materials differ?

A: The 2834960 uses Silver (Ag) contacts, while the 2903664 uses Silver Nickel (AgNi) contacts. Silver Nickel provides improved contact wear resistance and is standard in current Phoenix Contact relay designs.

Q: What compliance certifications apply to the substitute part?

A: The 2903664 carries ROHS3 compliance, representing the current regulatory standard. The obsolete 2834960 carried RoHS compliance. Both parts are EAR99 classified and meet HTSUS requirements for their respective categories.
