D4GL-4HFG-A Equivalent & Substitute Parts

Part Overview

The D4GL-4HFG-A is an interlock solenoid locking switch manufactured by Omron Automation and Safety. This component functions as a 3PST-NC + DPST-NC solenoid locking device with panel disconnect actuator type, designed for applications requiring secure mechanical locking with electrical interlock capability. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and support ongoing system maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4GL-4HFG-A is determined by the following critical parameters:

• Circuit Configuration: Both substitute parts maintain the identical 3PST-NC + DPST-NC circuit topology
• Voltage Supply: All parts operate on 24VDC supply voltage
• Actuator Type: Panel disconnect functionality is preserved across all alternatives
• Conduit Thread Size: M20 thread specification is consistent
• Operating Temperature Range: -10°C ~ 55°C range is maintained
• Ingress Protection: IP67 rating is retained
• Solenoid Locking Type: All parts function as solenoid locking devices

The D4SL-N series parts (D4SL-N4HFG-D and D4SL-N4HFG-DN) represent active product line alternatives from the same manufacturer. These parts differ in termination style (screw terminal versus connector) and holding force specifications, but maintain functional equivalence for interlock solenoid locking applications requiring the specified circuit configuration and supply voltage.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4HFG-D is the primary substitute for applications requiring screw terminal connections. This part maintains the same termination style as the D4GL-4HFG-A and is currently in active production status with confirmed inventory availability. Regulatory compliance includes CCC, CE, cURus, and TUV certifications, providing broader approval coverage than the original part.

D4SL-N4HFG-DN serves as an alternative for applications where connector-based termination is acceptable or preferred. This variant offers identical electrical and mechanical specifications to the D4SL-N4HFG-D, with the primary distinction being the connector termination style instead of screw terminals. This part is also in active production with confirmed inventory.

Both substitute parts are manufactured by Omron Automation and Safety, ensuring consistency in design philosophy, quality standards, and long-term support. The transition from the obsolete D4GL series to the active D4SL-N series represents a manufacturer product line evolution while maintaining functional compatibility for interlock solenoid locking applications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4HFG-D directly replace D4GL-4HFG-A in existing installations?

A: Yes, for applications using screw terminal connections. The D4SL-N4HFG-D maintains identical circuit configuration (3PST-NC + DPST-NC), 24VDC supply voltage, M20 conduit thread size, and IP67 ingress protection rating. Mechanical mounting and electrical interface compatibility should be verified against your specific installation requirements.

Q: What is the primary difference between D4SL-N4HFG-D and D4SL-N4HFG-DN?

A: The termination style differs. D4SL-N4HFG-D uses screw terminals, while D4SL-N4HFG-DN uses connector-based termination. All other electrical and mechanical parameters are identical. Selection depends on your wiring infrastructure and connection methodology.

Q: Are there differences in holding force between the main part and substitutes?

A: Yes. The D4GL-4HFG-A specifies 102kgf holding force, while both D4SL-N series parts specify 6kgf holding force. This represents a significant difference in mechanical locking capability. Applications requiring the original 102kgf holding force specification may not be suitable for substitution with the D4SL-N series.

Q: Do the substitute parts have the same regulatory approvals?

A: The substitute parts carry CCC, CE, cURus, and TUV certifications, compared to CE, cULus, and TUV for the original part. The D4SL-N series provides additional CCC and cURus approvals, which may be beneficial for certain regional or application-specific requirements.

Q: What is the current rating difference between the main part and substitutes?

A: The D4GL-4HFG-A is rated for 750mA AC at 240VAC. The D4SL-N series parts are rated for 1.5A AC at 120VAC and 220mA DC at 125VDC. These represent different electrical operating parameters and should be evaluated against your specific circuit requirements.

Q: Are both substitute parts currently available?

A: Yes. D4SL-N4HFG-D has 993 pieces in stock, and D4SL-N4HFG-DN has 824 pieces in stock, both listed as new original inventory from Omron Automation and Safety.
