Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2FFA-A4 is determined by equivalence in the following critical parameters:

• Circuit configuration: 3PST-2NC/1NO + DPST-NC topology
• Actuator type: Panel Disconnect
• Termination style: Screw Terminal
• Conduit thread size: G1/2
• Operating temperature range: -10°C ~ 55°C
• Ingress protection: IP67
• Mechanical form factor and mounting compatibility

The D4SL-N series (D4SL-N2FFA-D4 and D4SL-N2FFA-D4N) maintains identical circuit configuration, actuator type, termination style, conduit thread size, operating temperature range, and ingress protection rating. Both substitute parts are active products from the same manufacturer, ensuring design continuity and long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N2FFA-D4 and D4SL-N2FFA-D4N are active products suitable for replacing the obsolete D4GL-2FFA-A4. Selection between the two substitute parts should be based on packaging requirements and regulatory compliance needs for the target application.

The D4SL-N2FFA-D4 is supplied in bulk packaging and carries CCC, CE, cURus, and TUV certifications. The D4SL-N2FFA-D4N is also supplied in bulk packaging with identical certifications and includes documented MSL rating and ECCN classification.

Both substitutes provide increased holding force (133kgf versus 102kgf) and expanded voltage ratings (120VAC/125VDC versus 240VAC/24VDC). System design must accommodate these electrical parameter differences to ensure proper operation within the target application's voltage and current specifications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2FFA-D4 or D4SL-N2FFA-D4N directly replace D4GL-2FFA-A4 in existing installations?

A: Both D4SL-N series parts maintain identical circuit configuration (3PST-2NC/1NO + DPST-NC), actuator type (Panel Disconnect), termination style (Screw Terminal), conduit thread size (G1/2), operating temperature range (-10°C ~ 55°C), and ingress protection (IP67). Physical form factor compatibility must be confirmed for the specific installation. Electrical system parameters must accommodate the different voltage ratings and increased current capacity of the D4SL-N series.

Q: What are the key electrical differences between the D4GL-2FFA-A4 and D4SL-N substitutes?

A: The D4GL-2FFA-A4 operates at 24VDC supply with 240VAC switching at 750mA AC current. The D4SL-N2FFA-D4 and D4SL-N2FFA-D4N operate at 120VAC or 125VDC supply with 120VAC or 125VDC switching at 1.5A AC or 220mA DC current. System design must be evaluated to ensure compatibility with these different electrical specifications.

Q: Are there packaging differences between the substitute parts?

A: Both D4SL-N2FFA-D4 and D4SL-N2FFA-D4N are supplied in bulk packaging. The D4SL-N2FFA-D4N includes documented MSL rating (1 - Unlimited) and ECCN classification (EAR99), while the D4SL-N2FFA-D4 does not specify these parameters in available documentation.

Q: What regulatory certifications apply to the substitute parts?

A: Both D4SL-N2FFA-D4 and D4SL-N2FFA-D4N carry CCC, CE, cURus, and TUV approvals. The original D4GL-2FFA-A4 carried CE, cULus, and TUV approvals. Application requirements should determine which certification set is appropriate for the target market and regulatory environment.

Q: Why does the D4GL-2FFA-A4 show as obsolete?

A: The D4GL-2FFA-A4 is classified as obsolete by the manufacturer. The D4SL-N series represents the active product line continuation for this functional category, ensuring ongoing availability and support for new designs and system replacements.
