Equivalent & Substitute Parts for D4GL-1CFG-A

Part Overview

The D4GL-1CFG-A is an interlock solenoid locking switch manufactured by Omron Automation and Safety. This DPST (Double Pole Single Throw) device functions as a panel disconnect mechanism with dual circuit configuration (DPST-NO/NC + DPST-NC). The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain system functionality and ensure continued availability for replacement and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-1CFG-A are identified from the D4SL-N series, which maintains functional equivalence based on the following criteria:

Common Functional Parameters:

• Solenoid locking type mechanism
• DPST circuit configuration (DPST-NO/NC + DPST-NC)
• Panel disconnect actuator type
• IP67 ingress protection rating
• Operating temperature range (-10°C ~ 55°C)
• Screw terminal or connector termination options
• MSL rating 1 (Unlimited)

Substitution Basis: The D4SL-N series represents the active product line evolution from the obsolete D4GL series. Both series share identical circuit topology, environmental protection ratings, and mechanical interface specifications. The substitute parts maintain the same solenoid locking functionality and panel disconnect application requirements.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4CFG (Screw Terminal Configuration): This substitute maintains screw terminal termination identical to the D4GL-1CFG-A. Selection is appropriate for applications requiring direct screw-based wiring connections. The part is active and carries expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the obsolete original.

D4SL-N4CFG-N (Connector Configuration): This variant provides connector-based termination as an alternative to screw terminals. Selection is suitable for applications where connector-based interfaces are preferred or required. This part is also active with equivalent regulatory compliance.

Electrical Parameter Considerations: The D4SL-N series exhibits different electrical ratings than the D4GL-1CFG-A. The substitute parts support 1.5A AC and 220mA DC at 120VAC/125VDC, whereas the original operates at 750mA AC at 240VAC. Application compatibility must be verified against system voltage and current requirements.

Mechanical Parameter Considerations: The holding force differs significantly (6kgf for D4SL-N versus 102kgf for D4GL-1CFG-A). Conduit thread size changes from PG14.6 to M20. These mechanical differences require verification against mechanical mounting and force requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4CFG or D4SL-N4CFG-N directly replace D4GL-1CFG-A in existing installations?

A: Direct replacement requires verification of three critical parameters: (1) system voltage compatibility (120VAC/125VDC for substitutes versus 240VAC for original), (2) current requirements (1.5A AC maximum for substitutes versus 750mA for original), and (3) mechanical mounting compatibility (M20 conduit thread for substitutes versus PG14.6 for original). Holding force reduction from 102kgf to 6kgf must also be evaluated against application requirements.

Q: What is the primary difference between D4SL-N4CFG and D4SL-N4CFG-N?

A: The termination style differs. D4SL-N4CFG uses screw terminals, matching the original D4GL-1CFG-A configuration. D4SL-N4CFG-N uses connector-based termination. Both maintain identical circuit configuration, environmental ratings, and solenoid locking functionality.

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

A: The substitute parts carry expanded certifications (CCC, CE, cURus, TUV) compared to the original (CE, cULus, TUV). Both maintain CE and TUV approval. The substitutes include additional CCC and cURus certifications, providing broader regulatory coverage.

Q: What is the impact of the holding force difference?

A: The D4GL-1CFG-A provides 102kgf holding force, while D4SL-N substitutes provide 6kgf. This represents a significant reduction. Applications dependent on high holding force must be re-evaluated to determine if the lower force is acceptable for the intended mechanical locking function.

Q: Are there packaging differences between the substitute options?

A: Both D4SL-N4CFG and D4SL-N4CFG-N are supplied in bulk packaging. The original D4GL-1CFG-A packaging specification was not provided in the technical data.
