Omron D4GL-2CFA-A-SJ Interlock Solenoid Release Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2CFA-A-SJ is a DPST interlock solenoid release switch designed for panel disconnect applications. This component features a 24VDC supply voltage, 240VAC current rating at 750mA, and a holding force of 102kgf. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new installations where this specific model is no longer available from inventory channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-2CFA-A-SJ is based on the following critical parameters that must align for functional compatibility:

Mandatory Alignment Parameters:

• Actuator Type: Panel Disconnect
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Manufacturer: Omron Automation and Safety

Acceptable Variation Parameters:

• Current Rating: The substitute parts operate at different current ratings (1.5A AC / 220mA DC) compared to the main part (750mA AC). This represents a functional difference in load capacity.
• Voltage Rating: Substitute parts support 120VAC / 125VDC, differing from the main part's 240VAC rating.
• Holding Force: Substitute parts provide 6kgf versus the main part's 102kgf, indicating reduced mechanical holding capacity.
• Termination Style: Substitutes include both Screw Terminal and Connector options.
• Product Status: Substitute parts are Active, addressing the obsolescence of the main part.

The D4SL-N2CFA and D4SL-N2CFA-N are identified as substitute parts because they maintain the core functional architecture (solenoid release, panel disconnect, DPST circuit, IP67 protection, G1/2 conduit) while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

For D4SL-N2CFA Selection: This substitute maintains screw terminal termination, matching the original D4GL-2CFA-A-SJ configuration. The part is actively manufactured and carries expanded regulatory approvals (CCC, CE, cURus, TUV). Selection is appropriate when screw terminal connectivity is required and the reduced holding force (6kgf versus 102kgf) and lower voltage rating (120VAC/125VDC versus 240VAC) are compatible with system requirements.

For D4SL-N2CFA-N Selection: This variant provides connector-based termination instead of screw terminals. It shares identical electrical and mechanical specifications with the D4SL-N2CFA. Selection is appropriate when connector-based integration is preferred and the same electrical and force limitations apply.

Compliance Considerations: Both substitute parts carry CE, TUV, and additional CCC and cURus certifications, providing broader regulatory coverage than the obsolete main part. Both maintain IP67 ingress protection and unlimited moisture sensitivity rating, ensuring environmental performance parity.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2CFA or D4SL-N2CFA-N directly replace the D4GL-2CFA-A-SJ in existing installations?

A: Direct replacement requires verification of three critical parameters: (1) the system voltage must operate at 120VAC or 125VDC rather than 240VAC, (2) the load current must not exceed 1.5A AC or 220mA DC, and (3) the mechanical holding force requirement must not exceed 6kgf. If the original system operates at 240VAC or requires 102kgf holding force, these substitutes are not compatible.

Q: What is the difference between D4SL-N2CFA and D4SL-N2CFA-N?

A: The primary difference is termination style. The D4SL-N2CFA uses screw terminals, while the D4SL-N2CFA-N uses connector-based termination. All other electrical, mechanical, and environmental specifications are identical. Selection depends on the integration method required by the installation.

Q: Are the substitute parts currently available?

A: Yes. The D4SL-N2CFA has 839 pieces in stock, and the D4SL-N2CFA-N has 957 pieces in stock, both listed as new original inventory from Omron Automation and Safety.

Q: Do the substitute parts meet the same regulatory standards as the original?

A: The substitute parts exceed the original certification scope. The D4GL-2CFA-A-SJ carries CE, cULus, and TUV approvals. The D4SL-N2CFA and D4SL-N2CFA-N carry CCC, CE, cURus, and TUV approvals, providing additional regulatory coverage.

Q: What are the key electrical differences between the main part and substitutes?

A: The main part is rated for 240VAC at 750mA. The substitutes are rated for 120VAC at 1.5A AC or 125VDC at 220mA DC. These represent different voltage and current operating ranges and must be matched to system specifications.

Q: Can I use these substitutes in applications requiring 102kgf holding force?

A: No. The substitute parts provide only 6kgf holding force compared to the original 102kgf. Applications requiring the higher holding force must source alternative components rated for that specification.
