Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-4EFA-A4 are identified from the D4SL-N series based on the following critical parameters that determine functional equivalence:

Circuit configuration (3PST-2NC/1NO + DPST-NO/NC) must remain identical across all substitutes. Actuator type (Panel Disconnect) and conduit thread size (M20) must match. Operating temperature range (-10°C ~ 55°C) and ingress protection rating (IP67) must be maintained. All substitute candidates must be manufactured by Omron Automation and Safety and carry active product status to ensure ongoing availability and support.

The D4SL-N series meets these core requirements while offering enhanced electrical ratings and modern certification profiles compared to the obsolete D4GL series.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4EFA-D4 and D4SL-N4EFA-D4N are active products suitable for replacing the obsolete D4GL-4EFA-A4. Selection between these two substitutes depends on application-specific requirements:

D4SL-N4EFA-D4 features screw terminal termination and is appropriate for applications requiring the original termination style. This model carries expanded certification including CCC and cURus in addition to CE and TUV.

D4SL-N4EFA-D4N includes connector-based termination and explicit 24VDC supply voltage specification, making it suitable for applications requiring quick-disconnect capability or where supply voltage documentation is critical. This model also carries the same expanded certification profile.

Both substitutes maintain identical circuit configuration, actuator type, conduit thread size, operating temperature range, and ingress protection rating as the original part. The D4SL-N series offers higher AC current ratings (1.5A versus 750mA) and DC current capability, providing enhanced electrical performance margins.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4EFA-D4 and D4SL-N4EFA-D4N be used interchangeably?

A: Both parts share identical circuit configuration, voltage ratings, operating temperature, and ingress protection specifications. The primary differences are termination style (screw terminal versus connector) and holding force (133kgf versus 6kgf). Selection depends on whether the application requires screw terminal or connector termination and the specific holding force requirement.

Q: What is the impact of the holding force difference between D4SL-N4EFA-D4 (133kgf) and D4SL-N4EFA-D4N (6kgf)?

A: Holding force determines the mechanical clamping strength of the solenoid release. The D4SL-N4EFA-D4 provides higher holding force (133kgf) compared to the original D4GL-4EFA-A4 (102kgf), offering improved mechanical performance. The D4SL-N4EFA-D4N provides significantly lower holding force (6kgf) and is suitable only for applications where reduced clamping force is acceptable or required.

Q: Are the D4SL-N substitutes compatible with existing 24VDC supply systems?

A: D4SL-N4EFA-D4N explicitly specifies 24VDC supply voltage, matching the original part. D4SL-N4EFA-D4 does not specify supply voltage in the provided data; compatibility with 24VDC systems must be confirmed through detailed electrical specifications or manufacturer documentation.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N4EFA-D4 and D4SL-N4EFA-D4N carry CCC, CE, cURus, and TUV certifications. The original D4GL-4EFA-A4 carries CE, cULus, and TUV certifications. The D4SL-N series provides expanded regulatory coverage including CCC certification.

Q: Is the screw terminal termination of D4SL-N4EFA-D4 identical to the original D4GL-4EFA-A4?

A: Both parts specify screw terminal termination style. Mechanical compatibility with existing wiring harnesses and connector blocks must be confirmed through dimensional specifications and terminal pin configuration documentation.
