Phoenix Contact 2834070 General Purpose Relay DPDT 230VAC - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 2834070 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 230VAC coil voltage and 10A contact current. This socketable relay features mechanical and lighted indicators with a test button, designed for industrial control applications requiring reliable switching performance.
The 2834070 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure continued availability for maintenance and replacement, and support long-term operational requirements where original stock becomes depleted.

Substitute Part Grouping Explanation
Substitute parts for the Phoenix Contact 2834070 are identified based on the following critical parameters that determine functional compatibility:
- Contact form configuration (DPDT / 2 Form C)
- Coil voltage rating (230VAC)
- Socketable mounting type with plug-in termination
- Series compatibility (REL-IR)
- Contact current rating capability (minimum 10A)
- Operating temperature range compatibility
- RoHS compliance status
The Phoenix Contact 2834070 can be substituted with parts that maintain these core electrical and mechanical specifications. Variations in contact current rating above the 10A minimum, minor differences in coil current draw, and enhanced feature sets do not preclude substitution when the primary switching requirements are met.

Engineering Selection Recommendations
The Phoenix Contact 2903668 is a direct substitute for the 2834070 based on matching core specifications: identical series (REL-IR), contact form (DPDT), coil voltage (230VAC), socketable mounting, and plug-in termination. The 2903668 provides a higher contact current rating (12A versus 10A), which is compatible with applications designed for the original 10A specification.
Both parts are manufactured by Phoenix Contact within the same REL-IR series, ensuring mechanical and electrical compatibility within socketable relay bases. The 2903668 maintains the same functional architecture and control characteristics required for direct replacement in existing installations.
Selection between these parts should be based on availability and inventory status. The 2903668 currently maintains higher stock levels (1112 pieces) compared to the 2834070 (974 pieces), supporting long-term supply continuity.
Frequently Asked Questions (FAQ)
Q: Can the Phoenix Contact 2903668 directly replace the 2834070 in existing applications?
A: Yes. Both relays share identical contact form (DPDT), coil voltage (230VAC), series designation (REL-IR), and socketable mounting configuration. The 2903668 contact current rating of 12A exceeds the 2834070 specification of 10A, making it suitable for applications designed around the original 10A requirement.
Q: What are the critical parameters for substitution compatibility?
A: Contact form (DPDT), coil voltage (230VAC), mounting type (socketable), termination style (plug-in), and series compatibility (REL-IR) are the primary criteria. Contact current rating must meet or exceed the application requirement.
Q: Are there any mechanical compatibility concerns when substituting the 2903668 for the 2834070?
A: No mechanical compatibility issues exist. Both parts are socketable relays within the same Phoenix Contact REL-IR series, designed for identical base mounting and pin configurations.
Q: Does the higher contact current rating of the 2903668 affect circuit operation?
A: No. A relay with higher contact current rating operates identically to one with lower rating in applications within the lower rating's specification. The 2903668 simply provides additional capacity margin.
Q: Are both parts RoHS compliant?
A: The 2834070 is confirmed RoHS compliant. RoHS compliance status for the 2903668 is not specified in available documentation.
