Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4GL-4HFG-A4 is determined by the following critical parameters:

• Circuit configuration (3PST-NC + DPST-NC)
• Supply voltage (24VDC)
• Actuator type (Panel Disconnect)
• Conduit thread size (M20)
• Ingress protection rating (IP67)
• Operating temperature range (-10°C ~ 55°C)
• Solenoid locking function type

The substitute parts D4SL-N4HFG-D4 and D4SL-N4HFG-D4N meet these core functional and mechanical requirements. Both parts are from the D4SL-N series, an active product line from Omron Automation and Safety. The primary distinction between the two substitutes is termination style: D4SL-N4HFG-D4 uses screw terminal termination, while D4SL-N4HFG-D4N uses connector termination.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4HFG-D4 and D4SL-N4HFG-D4N are active products from Omron Automation and Safety and represent valid substitutes for the obsolete D4GL-4HFG-A4. The D4SL-N series provides equivalent functional performance across all critical parameters including circuit configuration, supply voltage, actuator type, and environmental protection ratings.

Selection between the two substitute options depends on termination requirements:

• D4SL-N4HFG-D4: Select when screw terminal connections are required to match existing wiring infrastructure.
• D4SL-N4HFG-D4N: Select when connector-based termination is preferred or when system design specifies connector interfaces.

Both substitutes carry expanded approval certifications (CCC, CE, cURus, TUV) compared to the original part, providing broader compliance coverage for international applications.

Frequently Asked Questions (FAQ)

Q: Why is the D4GL-4HFG-A4 no longer available?

A: The D4GL-4HFG-A4 is classified as obsolete. The D4SL-N series represents Omron's current active product line for this functional category and serves as the direct replacement platform.

Q: Are the substitute parts electrically compatible with the D4GL-4HFG-A4?

A: Yes. Both D4SL-N4HFG-D4 and D4SL-N4HFG-D4N maintain identical circuit configuration (3PST-NC + DPST-NC), supply voltage (24VDC), and functional specifications as the original part.

Q: What is the difference between D4SL-N4HFG-D4 and D4SL-N4HFG-D4N?

A: The primary difference is termination style. D4SL-N4HFG-D4 uses screw terminal connections, while D4SL-N4HFG-D4N uses connector termination. All other electrical and mechanical parameters are identical.

Q: Do the substitute parts meet the same environmental specifications?

A: Yes. Both substitutes maintain IP67 ingress protection rating, identical operating temperature range (-10°C ~ 55°C), and MSL 1 moisture sensitivity level as the original D4GL-4HFG-A4.

Q: Which substitute should I select for my application?

A: Selection depends on your existing wiring and connection infrastructure. If your system uses screw terminal connections, select D4SL-N4HFG-D4. If your system uses connector-based interfaces, select D4SL-N4HFG-D4N.

Q: Are there any compliance differences between the original and substitute parts?

A: The substitute parts carry additional certifications (CCC, cURus) beyond the original part's certifications (CE, cULus, TUV). Both maintain TUV and CE compliance, ensuring regulatory continuity.
