Phoenix Contact 2903692 General Purpose Relay DPDT 230VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2903692 is a general purpose relay with DPDT (Double Pole Double Throw, 2 Form C) configuration, rated for 10A at 230VAC coil voltage. This socketable relay is designed for standard industrial control applications requiring dual-channel switching capability. The REL-OR series provides reliable switching performance in general automation and control circuits where two independent switching channels are required.

Substitute parts become necessary when the original part is unavailable, when inventory constraints require alternative sourcing, or when application requirements allow for expanded contact configurations while maintaining core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2903692 is determined by the following critical parameters:

• Manufacturer consistency (Phoenix Contact)
• Series compatibility (REL-OR)
• Coil voltage matching (230VAC)
• Contact current rating (10A minimum)
• Socketable form factor compatibility

The substitute part 2903696 shares the same manufacturer, series, coil voltage, and contact rating. The primary difference is the contact configuration: the 2903696 provides 3PDT (3 Form C) instead of DPDT (2 Form C). This expanded contact configuration maintains all core electrical specifications while providing an additional switching channel. The 3PDT configuration is a superset of DPDT functionality, making it suitable for applications where additional switching capability is beneficial or required.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 2903692 and 2903696 depends on circuit requirements:

Use the 2903692 (DPDT) when the application requires exactly two independent switching channels and board space or cost constraints limit component selection.

Use the 2903696 (3PDT) when the application requires three independent switching channels, or when the 2903692 is unavailable and the circuit design can accommodate the additional contact set without modification. Both parts maintain identical electrical performance for the switching channels they share.

Both parts are from the same REL-OR series and share identical coil voltage, contact rating, and socketable construction, ensuring mechanical and electrical compatibility within the same relay socket.

Frequently Asked Questions (FAQ)

Q: Can the 2903696 (3PDT) directly replace the 2903692 (DPDT) in existing circuits?

A: Yes, mechanically and electrically. The 2903696 provides all functionality of the 2903692 plus one additional Form C contact set. Existing circuits using only two contact sets will function identically. The third contact set remains available for future expansion or can be left unused.

Q: What is the difference between DPDT and 3PDT configurations?

A: DPDT (Double Pole Double Throw) provides two independent Form C contact sets, each capable of switching between two positions. 3PDT (Triple Pole Double Throw) provides three independent Form C contact sets with identical switching capability. Both configurations use the same 10A contact rating and 230VAC coil voltage.

Q: Are both relays compatible with the same socket?

A: Yes. Both the 2903692 and 2903696 are socketable relays from the REL-OR series and are designed for the same relay socket interface.

Q: What inventory status should I consider when selecting between these parts?

A: The 2903692 has 954 pieces in stock, while the 2903696 has 943 pieces in stock. Both maintain adequate inventory for standard procurement.
