Omron D4GL-4BFG-A Interlock Solenoid Locking Switch - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4BFG-A is an interlock solenoid locking switch designed for panel disconnect applications with dual-pole switching capability. This component features a 24VDC supply voltage, 240VAC switching rating, and 102kgf holding force. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4GL-4BFG-A is determined by the following critical parameters:

Functional Compatibility Criteria:

• Solenoid locking switch type with panel disconnect actuator
• DPST circuit configuration (dual-pole switching)
• M20 conduit thread size
• IP67 ingress protection rating
• Operating temperature range -10°C ~ 55°C
• Screw terminal or connector termination compatibility

Electrical Compatibility Criteria:

• Voltage switching capability (minimum 240VAC or equivalent DC rating)
• Current handling capacity (minimum 750mA AC or equivalent)
• Supply voltage compatibility or adapter feasibility

The D4SL-N series (D4SL-N4BFG and D4SL-N4BFG-N) are identified as active substitutes. Both variants maintain the same circuit configuration, actuator type, conduit thread size, ingress protection, operating temperature range, and approval certifications. Differences in current rating, voltage rating, holding force, and termination style represent trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4BFG (Screw Terminal Variant): This substitute maintains screw terminal termination identical to the D4GL-4BFG-A, reducing installation modifications. The part is active with current manufacturing status and carries expanded approval certifications (CCC, CE, cURus, TUV). Selection is appropriate for applications where existing screw terminal wiring infrastructure is in place and where the reduced holding force (6kgf versus 102kgf) and lower voltage rating (120VAC versus 240VAC) are acceptable within system design parameters.

D4SL-N4BFG-N (Connector Termination Variant): This substitute provides connector-based termination, requiring interface adaptation from the original screw terminal design. The part is active with identical approval certifications and electrical specifications to the D4SL-N4BFG variant. Selection is appropriate for new system designs or retrofit applications where connector standardization is preferred and mechanical/electrical specifications align with application requirements.

Substitution Feasibility: Both D4SL-N series variants are direct functional substitutes from Omron's active product portfolio. The primary selection criterion between variants is termination style compatibility with existing or planned installation infrastructure. Electrical parameter differences (current, voltage, holding force) must be evaluated against specific application load and supply requirements.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N4BFG or D4SL-N4BFG-N directly replace the D4GL-4BFG-A without modification?

A: Both D4SL-N variants maintain identical circuit configuration, actuator type, conduit thread size, ingress protection, and operating temperature range. The D4SL-N4BFG retains screw terminal termination. Substitution feasibility depends on whether the reduced holding force (6kgf versus 102kgf) and lower voltage rating (120VAC versus 240VAC) are compatible with application requirements. Mechanical mounting and electrical interface compatibility must be confirmed.

Q: What is the primary difference between D4SL-N4BFG and D4SL-N4BFG-N?

A: The D4SL-N4BFG features screw terminal termination, while the D4SL-N4BFG-N uses connector termination. All other electrical and mechanical specifications are identical. Selection depends on installation infrastructure and wiring methodology.

Q: Why does the D4SL-N series have lower holding force than the D4GL-4BFG-A?

A: The D4GL-4BFG-A and D4SL-N series represent different product lines within Omron's solenoid locking switch portfolio, each designed for specific application classes. The D4SL-N series is rated for 6kgf holding force, while the D4GL-4BFG-A is rated for 102kgf. Application requirements determine which holding force specification is appropriate.

Q: Are the approval certifications equivalent between the obsolete and active parts?

A: The D4GL-4BFG-A carries CE, cULus, and TUV certifications. The D4SL-N variants carry CCC, CE, cURus, and TUV certifications. Both meet CE and TUV standards. The D4SL-N variants include additional CCC certification and cURus (versus cULus). Certification requirements for your application determine whether the expanded certification set is beneficial or irrelevant.

Q: What inventory status should be considered for procurement?

A: The D4GL-4BFG-A is obsolete with 833 units in stock. The D4SL-N4BFG has 872 units in stock, and the D4SL-N4BFG-N has 887 units in stock. Both active substitutes have comparable inventory availability. For long-term supply chain planning, active product status of the D4SL-N series provides greater assurance of continued availability.
