Equivalent & Substitute Parts for D4GL-1CFG-A4

Part Overview

The D4GL-1CFG-A4 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 part is classified as obsolete, necessitating identification of active equivalent models to maintain system functionality and ensure continued availability for maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-1CFG-A4 is based on the following critical parameters that must align across equivalent models:

Mandatory Matching Parameters:

• Type: Solenoid Locking
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Actuator Type: Panel Disconnect
• Ingress Protection: IP67
• Operating Temperature Range: -10°C ~ 55°C
• Approval Agencies: Minimum CE and TUV certification

Allowable Variations:

• Termination Style: Screw Terminal or Connector acceptable
• Current Rating: Substitute must support minimum 750mA AC
• Voltage Rating: Substitute must support minimum 240VAC
• Holding Force: Substitute specifications may differ from 102kgf
• Supply Voltage: May differ from 24VDC

The D4SL-N series (D4SL-N4CFG and D4SL-N4CFG-N) maintains the core solenoid locking functionality, DPST circuit configuration, panel disconnect actuator, IP67 protection, and required certifications. Both variants are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4CFG (Screw Terminal Configuration)

This variant maintains screw terminal termination matching the original D4GL-1CFG-A4. The D4SL-N4CFG is an active product with current manufacturing status and full compliance certifications (CCC, CE, cURus, TUV). Selection of this variant is appropriate for applications where existing screw terminal wiring infrastructure is in place and no connector modification is required.

D4SL-N4CFG-N (Connector Configuration)

This variant features connector-based termination, differing from the original screw terminal design. The D4SL-N4CFG-N is an active product with equivalent compliance certifications. Selection of this variant requires assessment of connector compatibility with existing installation infrastructure.

Common Considerations

Both D4SL-N variants provide higher AC current capacity (1.5A versus 750mA) and expanded voltage rating options (120VAC/125VDC). The reduced holding force specification (6kgf versus 102kgf) must be evaluated against application requirements. Both variants maintain IP67 ingress protection and the required operating temperature range. Conduit thread size differs (M20 versus PG14.6), requiring mechanical interface verification.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4CFG or D4SL-N4CFG-N directly replace D4GL-1CFG-A4?

A: Both D4SL-N variants maintain the core solenoid locking functionality, DPST circuit configuration, panel disconnect actuator type, and IP67 protection rating. Mechanical interface compatibility must be verified due to differences in conduit thread size (M20 versus PG14.6) and holding force specification (6kgf versus 102kgf).

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

A: The termination style differs. D4SL-N4CFG uses screw terminals, while D4SL-N4CFG-N uses connector-based termination. Both maintain identical electrical specifications and certifications.

Q: Are the voltage and current ratings compatible?

A: The D4SL-N variants support higher AC current capacity (1.5A) compared to the original specification (750mA). Voltage ratings differ: D4SL-N supports 120VAC/125VDC, while D4GL-1CFG-A4 is rated for 240VAC. Application voltage requirements must be verified before selection.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N4CFG and D4SL-N4CFG-N carry CCC, CE, cURus, and TUV certifications, providing broader regulatory coverage than the original D4GL-1CFG-A4 (CE, cULus, TUV).

Q: How does the holding force difference affect substitution?

A: The D4SL-N variants specify 6kgf holding force compared to 102kgf for the original part. Applications requiring the higher holding force specification must evaluate whether the reduced force is acceptable for the intended use case.

Q: What is the inventory status of substitute parts?

A: D4SL-N4CFG has 1175 pieces in stock, and D4SL-N4CFG-N has 641 pieces in stock, both as new original inventory from Omron Automation and Safety.
