Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-2DFA-A4 is based on the following critical parameters that must align across equivalent parts:

Mandatory Matching Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Release
• Circuit Configuration: DPST-NC x 2
• Actuator Type: Panel Disconnect
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Termination compatibility with system requirements

Identified Substitute Series: The D4SL-N series represents the active product line replacement for the obsolete D4GL series. Both substitute parts (D4SL-N2DFA and D4SL-N2DFA-N) maintain the core functional parameters and environmental ratings required for interlock solenoid release applications.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2DFA (Screw Terminal Configuration): This substitute maintains screw terminal termination identical to the original D4GL-2DFA-A4. Selection of this variant is appropriate for applications where existing wiring harnesses and connection infrastructure are designed for screw terminal interfaces. The part is active and carries expanded regulatory approvals including CCC certification.

D4SL-N2DFA-N (Connector Configuration): This variant provides the same electrical and mechanical functionality as D4SL-N2DFA but with connector-based termination. Selection is appropriate for applications requiring connector-based integration or where system redesign permits connector implementation. This part is also active with equivalent regulatory compliance.

Voltage and Current Considerations: The D4SL-N series operates at 120VAC/125VDC with current ratings of 1.5A (AC) and 220mA (DC), differing from the original D4GL-2DFA-A4 specification of 240VAC at 750mA. System voltage and current requirements must be evaluated during substitution planning to ensure compatibility with existing power supply and control circuit specifications.

Holding Force Differential: The D4SL-N series provides 6kgf holding force compared to the original 102kgf. Applications dependent on the higher holding force specification require engineering evaluation to determine if the reduced force is acceptable for the intended mechanical load conditions.

Frequently Asked Questions (FAQ)

Q: Why is the D4GL-2DFA-A4 no longer available? A: The D4GL-2DFA-A4 is classified as obsolete. Omron has transitioned this product line to the active D4SL-N series, which provides equivalent functionality with updated regulatory compliance and manufacturing support.

Q: What is the primary difference between D4SL-N2DFA and D4SL-N2DFA-N? A: The termination style differs. D4SL-N2DFA uses screw terminals, while D4SL-N2DFA-N uses connector termination. Both maintain identical electrical specifications and mechanical form factors.

Q: Can I directly replace D4GL-2DFA-A4 with D4SL-N2DFA? A: Direct replacement requires verification of voltage and current compatibility. The D4SL-N2DFA operates at 120VAC/125VDC with 1.5A (AC) and 220mA (DC) ratings, whereas the original operates at 240VAC with 750mA. System power supply specifications must support the substitute part's voltage and current requirements.

Q: Does the reduced holding force of D4SL-N series affect functionality? A: The D4SL-N series provides 6kgf holding force compared to the original 102kgf. Applications must be evaluated to determine if this force reduction is acceptable for the mechanical load and safety requirements of the specific installation.

Q: Are the regulatory approvals equivalent between the original and substitute parts? A: Both substitute parts carry CE, cURus, and TUV approvals. The D4SL-N series additionally includes CCC certification. Existing approvals for the original D4GL-2DFA-A4 (CE, cULus, TUV) are maintained or expanded in the substitute parts.

Q: What inventory status should I expect for these substitute parts? A: D4SL-N2DFA carries 2100 units in stock, and D4SL-N2DFA-N carries 698 units in stock, indicating active product availability from Omron.
