Phoenix Contact 2903296 General Purpose Relay DPDT 120VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2903296 is a general purpose relay with DPDT (2 Form C) contact configuration, designed for 120VAC coil operation on DIN rail mounting. This relay features a 7A contact rating, lighted indicator, socket inclusion, and varistor protection. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2903296 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Phoenix Contact
• Series: RIF
• Mounting Type: DIN Rail
• Coil Voltage: 120VAC
• Coil Type: Non Latching
• Coil Current: 23 mA
• Termination Style: Spring Terminal
• Contact Material: Silver Nickel (AgNi)
• Operating Temperature Range: -40°C ~ 50°C

Allowable Variation Parameters:

• Contact Form: DPDT (2 Form C) or 3PDT (3 Form C) - both provide equivalent switching capability with compatible contact configurations
• Contact Rating (Current): 6A to 7A - both ratings support the same switching voltage and application envelope
• Features: Lighted Indicator, Socket Included, Varistor - consistent across substitute options

The Phoenix Contact 2903293 qualifies as a substitute based on these criteria, with the primary difference being contact form configuration (3PDT vs. DPDT) and a 1A reduction in contact rating (6A vs. 7A).

Engineering Selection Recommendations

The Phoenix Contact 2903293 is the identified substitute for the obsolete 2903296. Selection should be based on the following factors:

Product Status Consideration: The 2903293 maintains Active product status, ensuring continued availability and manufacturer support, whereas the 2903296 is Obsolete. This makes the 2903293 the appropriate choice for new designs and ongoing system support.

Compliance Advantage: The 2903293 carries ROHS3 Compliant certification compared to the RoHS Compliant status of the 2903296, providing enhanced environmental compliance alignment with current regulatory requirements.

Contact Configuration Difference: The 2903293 provides 3PDT (3 Form C) switching versus the 2903296's DPDT (2 Form C) configuration. The additional contact set in the 2903293 expands switching capability while maintaining identical coil, timing, and environmental specifications.

Current Rating Consideration: The 2903293 is rated at 6A versus the 2903296's 7A. Both ratings operate within the same 250VAC/250VDC maximum switching voltage envelope. Application-specific current requirements must be evaluated to confirm the 6A rating is sufficient for the intended load.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903293 directly replace the 2903296 in existing installations?

A: The 2903293 is functionally equivalent for applications requiring 120VAC coil operation, DIN rail mounting, and non-latching relay operation. The primary consideration is the contact form difference: 3PDT versus DPDT. If the application uses only two contact sets, the additional third contact set in the 2903293 remains unused but does not prevent operation. The 6A contact rating must be confirmed as adequate for the application load.

Q: What is the significance of the contact form difference between DPDT and 3PDT?

A: DPDT (2 Form C) provides two independent changeover contact sets. 3PDT (3 Form C) provides three independent changeover contact sets. The 2903293 offers additional switching capability. If the application requires only two contact sets, the third set is available for future expansion or alternative circuit configurations.

Q: Are there compatibility concerns with the 1A difference in contact rating?

A: The contact rating difference (7A vs. 6A) reflects the maximum continuous current each relay can switch. Both relays operate at the same 250VAC/250VDC maximum switching voltage. Applications operating below 6A continuous current are unaffected. Applications requiring 6A to 7A continuous current must be evaluated against the 2903293's 6A specification.

Q: What packaging differences exist between these parts?

A: The 2903296 is specified with "-" packaging notation, while the 2903293 is supplied in Bulk packaging. Both are DIN rail mounted components with identical form factors and mounting requirements.

Q: How do the RoHS compliance levels differ?

A: The 2903296 carries RoHS Compliant certification. The 2903293 carries ROHS3 Compliant certification, representing a more recent compliance standard. ROHS3 compliance includes additional restricted substance requirements and is the current industry standard for new component designs.

Q: Are the coil specifications identical between these relays?

A: Yes. Both relays operate on 120VAC coil voltage, draw 23mA coil current, and feature non-latching coil operation. Timing specifications are identical: 15ms operate time and 20ms release time. Both operate across the -40°C to 50°C temperature range.
