Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2CFA-A4 is based on the following critical parameters that must align across alternatives:

Mandatory Matching Parameters:

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

Identified Substitutes: The D4SL-N2CFA and D4SL-N2CFA-N are active Omron solenoid release switches that maintain the same circuit configuration, actuator type, conduit thread size, operating temperature range, and IP67 ingress protection rating. Both parts are from the D4SL-N series and represent current production alternatives to the obsolete D4GL series.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2CFA (Screw Terminal Configuration) This substitute maintains screw terminal termination identical to the D4GL-2CFA-A4. Both D4SL-N series alternatives are active products with current manufacturing support and expanded regulatory approvals including CCC certification. The D4SL-N2CFA is suitable for applications requiring direct terminal connection compatibility.

D4SL-N2CFA-N (Connector Configuration) This variant provides the same electrical and mechanical specifications as the D4SL-N2CFA but with connector-based termination. Selection of this part depends on system design requirements for connector-based integration.

Compliance Considerations Both substitute parts carry CE, cURus, and TUV certifications, with additional CCC approval. The D4GL-2CFA-A4 carries cULus certification; the D4SL-N series carries cURus certification. Regulatory requirements for the target application must be evaluated to confirm certification alignment.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2CFA or D4SL-N2CFA-N directly replace D4GL-2CFA-A4 in existing installations? A: Both D4SL-N series parts maintain identical circuit configuration (DPST-NO/NC + DPST-NC), actuator type (Panel Disconnect), conduit thread size (G1/2), operating temperature range (-10°C to 55°C), and IP67 ingress protection. The D4SL-N2CFA provides screw terminal compatibility. Physical mounting and electrical connection points must be verified against system documentation.

Q: What are the key electrical differences between the D4GL-2CFA-A4 and D4SL-N substitutes? A: The D4GL-2CFA-A4 is rated for 750mA AC at 240VAC with 24VDC supply. The D4SL-N2CFA and D4SL-N2CFA-N are rated for 1.5A AC at 120VAC and 220mA DC at 125VDC. The D4GL-2CFA-A4 provides 102kgf holding force, while D4SL-N variants provide 6kgf holding force. Application voltage and current requirements must be evaluated for compatibility.

Q: What is the difference between D4SL-N2CFA and D4SL-N2CFA-N? A: The primary difference is termination style. D4SL-N2CFA uses screw terminals, matching the D4GL-2CFA-A4 configuration. D4SL-N2CFA-N uses connector-based termination. All other electrical and mechanical specifications are identical.

Q: Are there supply voltage differences I should consider? A: The D4GL-2CFA-A4 specifies 24VDC supply voltage. The D4SL-N series does not specify supply voltage in the provided parameters. System supply voltage requirements must be confirmed against complete technical documentation before implementation.

Q: What certifications apply to each part? A: D4GL-2CFA-A4 carries CE, cULus, and TUV approvals. D4SL-N2CFA and D4SL-N2CFA-N carry CCC, CE, cURus, and TUV approvals. Regulatory requirements for the target market and application must be verified.
