Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-4FFG-A4 is based on the following critical parameters that must remain consistent:

• Circuit configuration: 3PST-2NC/1NO + DPST-NC
• Supply voltage: 24VDC
• Actuator type: Panel Disconnect
• Conduit thread size: M20
• Operating temperature range: -10°C ~ 55°C
• Ingress protection: IP67
• Status indicator feature

The D4SL-N series (D4SL-N4FFG-D4 and D4SL-N4FFG-D4N) maintains identical circuit configuration, supply voltage, actuator type, conduit thread size, temperature range, ingress protection, and status indicator functionality. Both substitute parts are active products from Omron Automation and Safety, providing continuity for applications previously using the obsolete D4GL-4FFG-A4.

The primary distinction between substitute parts is termination style: D4SL-N4FFG-D4 uses screw terminal (matching the original), while D4SL-N4FFG-D4N uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4FFG-D4 and D4SL-N4FFG-D4N are active Omron products suitable for replacing the obsolete D4GL-4FFG-A4 in panel disconnect applications. The D4SL-N series maintains functional equivalence through identical circuit configuration, supply voltage, actuator type, and environmental specifications.

For applications requiring screw terminal connectivity matching the original D4GL-4FFG-A4 installation, select D4SL-N4FFG-D4. For new installations or applications where connector termination is preferred, D4SL-N4FFG-D4N provides the same functional performance with alternative termination.

Both substitute parts carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part, supporting compliance requirements across multiple markets. The D4SL-N series is RoHS compliant, meeting current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4FFG-D4 directly replace D4GL-4FFG-A4 in existing installations?

A: Yes. Both parts share identical circuit configuration (3PST-2NC/1NO + DPST-NC), 24VDC supply voltage, M20 conduit thread size, IP67 ingress protection, and screw terminal termination. The D4SL-N4FFG-D4 is functionally equivalent for panel disconnect applications.

Q: What is the difference between D4SL-N4FFG-D4 and D4SL-N4FFG-D4N?

A: The primary difference is termination style. D4SL-N4FFG-D4 uses screw terminals, while D4SL-N4FFG-D4N uses connector termination. Both maintain identical circuit configuration, supply voltage, and environmental specifications.

Q: Are there voltage rating differences between the original and substitute parts?

A: Yes. The D4GL-4FFG-A4 is rated for 240VAC switching, while D4SL-N4FFG-D4 and D4SL-N4FFG-D4N are rated for 120VAC and 125VDC. Applications requiring 240VAC switching must evaluate load compatibility with the substitute parts' voltage ratings.

Q: What is the holding force difference?

A: The D4GL-4FFG-A4 provides 102kgf holding force, while D4SL-N4FFG-D4 and D4SL-N4FFG-D4N provide 6kgf. Applications dependent on the original 102kgf holding force specification require evaluation of mechanical requirements against the substitute parts' reduced holding force.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both D4SL-N4FFG-D4 and D4SL-N4FFG-D4N are RoHS compliant, meeting current environmental standards for electronic components.

Q: What regulatory approvals do the substitute parts carry?

A: D4SL-N4FFG-D4 and D4SL-N4FFG-D4N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the original D4GL-4FFG-A4 (CE, cULus, TUV).
