Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2BFG-A is based on the following critical parameters that define functional equivalence:

Primary Compatibility Criteria:

• Manufacturer: Omron Automation and Safety (same manufacturer ensures design compatibility)
• Type: Solenoid Locking (functional requirement)
• Circuit Configuration: DPST-NO/NC + DPST-NC (switching topology)
• Actuator Type: Panel Disconnect (mechanical interface)
• Conduit Thread Size: G1/2 (mechanical mounting)
• Ingress Protection: IP67 (environmental sealing requirement)
• Operating Temperature Range: -10°C to 55°C (thermal compatibility)

Secondary Compatibility Considerations:

• Termination Style: Screw Terminal or Connector (both acceptable for electrical connection)
• Product Status: Active (ensures ongoing availability and support)

The identified substitute parts D4SL-N2BFG and D4SL-N2BFG-N belong to the D4SL-N series and maintain all primary compatibility criteria. Both parts are active products with current manufacturing status, providing long-term supply assurance.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2BFG (Screw Terminal Configuration)

This substitute maintains screw terminal termination identical to the D4GL-2BFG-A, providing direct compatibility with existing wiring harnesses and installation practices. The D4SL-N2BFG is an active product with 1013 units in current inventory, ensuring immediate availability. Regulatory compliance includes CCC, CE, cURus, and TUV certifications, exceeding the original part's approval scope. The ECCN classification of EAR99 and HTSUS code 8536.50.9055 confirm standard commercial availability.

D4SL-N2BFG-N (Connector Configuration)

This substitute provides identical electrical and mechanical functionality with connector-based termination instead of screw terminals. Selection of this variant is appropriate for applications where connector-based assembly is preferred or required. The D4SL-N2BFG-N maintains active product status with 746 units in inventory and equivalent regulatory certifications.

Critical Design Consideration

The substitute parts operate at reduced holding force (6kgf versus 102kgf) and different voltage ratings (120VAC/125VDC versus 240VAC/24VDC). These differences require application-level assessment to confirm compatibility with the intended use case. The D4SL-N series is suitable for applications where the lower holding force and different voltage specifications align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2BFG or D4SL-N2BFG-N directly replace D4GL-2BFG-A in all applications?

A: Both D4SL-N variants maintain identical circuit configuration, actuator type, conduit thread size, operating temperature range, and ingress protection rating. However, the holding force is significantly lower (6kgf versus 102kgf) and voltage ratings differ (120VAC/125VDC versus 240VAC/24VDC). Direct replacement is only appropriate for applications where these performance differences are acceptable.

Q: What is the difference between D4SL-N2BFG and D4SL-N2BFG-N?

A: The primary difference is termination style. D4SL-N2BFG uses screw terminals, matching the original D4GL-2BFG-A configuration. D4SL-N2BFG-N uses connector-based termination. Both parts are electrically and mechanically identical otherwise. Selection depends on installation method and wiring infrastructure.

Q: Why is the D4GL-2BFG-A classified as obsolete?

A: The D4GL series has been superseded by the D4SL-N series within Omron's product portfolio. The D4SL-N series provides equivalent functionality with active manufacturing status and broader regulatory certifications.

Q: Are the substitute parts available in the same packaging as the original?

A: The D4GL-2BFG-A was packaged as individual units. Both D4SL-N2BFG and D4SL-N2BFG-N are supplied in bulk packaging. Procurement quantities should account for this packaging difference.

Q: Do the substitute parts carry the same regulatory approvals?

A: The substitute parts carry expanded regulatory certifications. D4GL-2BFG-A holds CE, cULus, and TUV approvals. D4SL-N variants hold CCC, CE, cURus, and TUV approvals, providing broader market compliance.

Q: What is the current inventory status of substitute parts?

A: D4SL-N2BFG has 1013 units in stock. D4SL-N2BFG-N has 746 units in stock. Both are active products with ongoing manufacturing support.
