Substitute Part Grouping Explanation
Substitution for the D4GL-1FFA-A is based on the following critical parameters that must align for functional equivalence:
Mandatory Matching Parameters:
- Circuit configuration: 3PST-2NC/1NO + DPST-NC
- Supply voltage: 24VDC
- Actuator type: Panel Disconnect
- Ingress protection: IP67
- Operating temperature range: -10°C ~ 55°C
- Features: Status Indicator
Allowable Variations:
- Holding force may differ (substitute parts rated at 6kgf versus original 102kgf)
- Current rating and switching voltage may vary within application requirements
- Termination style may differ (Screw Terminal versus Connector)
- Conduit thread size may differ (PG14.6 versus M20)
- Approval agencies may differ while maintaining equivalent certifications
The D4SL-N series parts meet the core functional requirements while offering active product status and modern certification profiles.

Engineering Selection Recommendations
D4SL-N4FFA-D is suitable for applications requiring screw terminal connections. This part maintains active product status with current manufacturing support and expanded certification coverage (CCC, CE, cURus, TUV). The reduced holding force of 6kgf versus the original 102kgf requires verification against application load requirements. Switching voltage is reduced to 120VAC/125VDC, necessitating confirmation that this aligns with system specifications.
D4SL-N4FFA-DN provides identical electrical and mechanical specifications to the D4SL-N4FFA-D but features connector-based termination instead of screw terminals. This variant is appropriate for applications where connector-based integration is preferred or required by system design.
Both D4SL-N series substitutes provide equivalent circuit functionality, supply voltage compatibility, and environmental protection ratings. Selection between these two variants depends solely on termination style requirements: screw terminal (D4SL-N4FFA-D) or connector (D4SL-N4FFA-DN).
Frequently Asked Questions (FAQ)
Q: Can the D4SL-N4FFA-D directly replace the D4GL-1FFA-A?
A: Functional substitution is possible if the application load requirement does not exceed 6kgf holding force and the switching voltage requirement does not exceed 120VAC/125VDC. The circuit configuration, supply voltage, actuator type, and environmental protection are equivalent.
Q: What is the primary difference between D4SL-N4FFA-D and D4SL-N4FFA-DN?
A: The termination style differs. D4SL-N4FFA-D uses screw terminals, while D4SL-N4FFA-DN uses connector-based termination. All other electrical and mechanical parameters are identical.
Q: Why is the holding force significantly lower in the D4SL-N series?
A: The D4SL-N series is designed for different application requirements. The 6kgf holding force must be evaluated against the specific load demands of the target application.
Q: Are the approval certifications equivalent between the D4GL-1FFA-A and D4SL-N series?
A: The D4SL-N series includes additional certifications (CCC, cURus) beyond the original part's certifications (CE, cULus, TUV). Both maintain TUV and CE compliance. Regional certification requirements should be confirmed for the target market.
Q: What is the inventory status for these substitute parts?
A: D4SL-N4FFA-D has 711 units in stock. D4SL-N4FFA-DN has 1054 units in stock. Both are active products with ongoing availability.
