Substitute Part Grouping Explanation

Substitute parts for the D4GL-4DFG-A are identified from the D4SL-N series based on the following allowed parameters:

Common Functional Parameters:

Manufacturer: Omron Automation and Safety
Type: Solenoid Locking
Circuit Configuration: DPST-NC x 2
Actuator Type: Panel Disconnect
Conduit Thread Size: M20
Operating Temperature Range: -10°C ~ 55°C
Ingress Protection: IP67
Moisture Sensitivity Level: 1 (Unlimited)

Electrical Compatibility Considerations: The D4SL-N series substitutes operate at different voltage and current ratings than the main part. The D4GL-4DFG-A is rated for 240VAC at 750mA with 24VDC supply, while D4SL-N variants are rated for 120VAC/125VDC at 1.5A (AC) or 220mA (DC). These differences require circuit-level evaluation for compatibility.

Mechanical Compatibility: Both substitute parts maintain M20 conduit thread size and IP67 ingress protection. Holding force differs significantly: D4GL-4DFG-A provides 102kgf versus 6kgf for D4SL-N variants. Termination style varies between screw terminal and connector options.

Engineering Selection Recommendations

Product Status Consideration: The D4GL-4DFG-A is obsolete. The D4SL-N4DFG and D4SL-N4DFG-N are both active products from the same manufacturer, providing ongoing availability and support.

Compliance and Certification: Both substitute parts carry CE, TUV, and additional CCC and cURus certifications, meeting or exceeding the regulatory requirements of the original part.

Termination Selection: D4SL-N4DFG provides screw terminal termination matching the original D4GL-4DFG-A. D4SL-N4DFG-N uses connector termination and requires mechanical interface adaptation.

Electrical Rating Differences: Substitution requires verification that circuit voltage and current requirements align with D4SL-N specifications (120VAC/125VDC, 1.5A AC, 220mA DC). The D4GL-4DFG-A operates at higher voltage (240VAC) and lower current (750mA), representing a different electrical class.

Mechanical Force Consideration: The D4GL-4DFG-A provides significantly higher holding force (102kgf) compared to D4SL-N variants (6kgf). Application requirements must accommodate this reduction in clamping force.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4DFG directly replace D4GL-4DFG-A in existing installations?

A: Direct replacement requires verification of three factors: circuit voltage compatibility (240VAC vs. 120VAC), holding force adequacy (102kgf vs. 6kgf), and termination interface (screw terminal match). Electrical circuit redesign may be necessary.

Q: What is the primary difference between D4SL-N4DFG and D4SL-N4DFG-N?

A: The termination style differs. D4SL-N4DFG uses screw terminal connection, while D4SL-N4DFG-N uses connector termination. Both maintain identical electrical ratings and mechanical specifications.

Q: Why does the D4GL-4DFG-A have higher holding force than the D4SL-N series?

A: The D4GL and D4SL-N are distinct product series designed for different application classes. The D4GL-4DFG-A is engineered for high-force locking applications, while D4SL-N variants serve lower-force requirements.

Q: Are the substitute parts certified for the same regulatory standards?

A: Both D4SL-N variants carry CE, TUV, CCC, and cURus certifications. The original D4GL-4DFG-A carries CE, cULus, and TUV. Regulatory compliance must be verified for the specific application jurisdiction.

Q: What is the inventory status of these parts?

A: D4GL-4DFG-A: 1021 pcs in stock (obsolete status). D4SL-N4DFG: 1055 pcs in stock (active). D4SL-N4DFG-N: 767 pcs in stock (active).
