Omron D4GL-2FFA-A Interlock Solenoid Release Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2FFA-A is an interlock solenoid release switch classified as a 3PST (3-pole, single-throw) configuration with integrated status indicator functionality. This component operates at 240VAC with 24VDC supply voltage and delivers a holding force of 102kgf, designed for panel disconnect applications requiring dust-tight and waterproof sealing (IP67).

The D4GL-2FFA-A carries obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement, repair, and new installations where this legacy component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D4GL-2FFA-A are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Circuit configuration: 3PST-2NC/1NO + DPST-NC (identical contact arrangement)
• Actuator type: Panel Disconnect (same mechanical interface)
• Termination style: Screw Terminal (identical connection method)
• Conduit thread size: G1/2 (same mounting interface)
• Operating temperature range: -10°C to 55°C (identical environmental specification)
• Ingress protection: IP67 (identical sealing requirement)

Secondary Compatibility Factors:

• Manufacturer: Omron Automation and Safety (same manufacturer ecosystem)
• Type: Solenoid Release (identical functional classification)
• Holding force: 133kgf (substitute exceeds minimum requirement of 102kgf)

The substitute parts D4SL-N2FFA-D and D4SL-N2FFA-DN belong to the active D4SL-N series and maintain all critical mechanical and environmental parameters. Both substitutes provide enhanced electrical ratings (1.5A AC / 220mA DC at 120VAC / 125VDC) compared to the original specification, ensuring compatibility in applications where the D4GL-2FFA-A was previously deployed.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2FFA-D and D4SL-N2FFA-DN Selection Basis:

Both substitute parts are classified as active products within the Omron D4SL-N series, ensuring long-term availability and continued manufacturer support. The substitutes maintain identical mechanical interfaces (panel disconnect actuator, G1/2 conduit thread, screw terminal configuration) and environmental specifications (IP67 ingress protection, -10°C to 55°C operating range) as the obsolete D4GL-2FFA-A.

The D4SL-N series components carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part (CE, cULus, TUV), providing broader compliance coverage for international applications.

Electrical Specification Differences:

The substitute parts operate at 120VAC / 125VDC with current ratings of 1.5A (AC) and 220mA (DC), differing from the original 240VAC / 750mA (AC) specification. Applications requiring the original 240VAC supply voltage must evaluate circuit redesign or alternative component selection. The increased holding force (133kgf versus 102kgf) in substitute parts provides enhanced mechanical performance for panel disconnect applications.

Packaging Consideration:

D4SL-N2FFA-D and D4SL-N2FFA-DN are supplied in bulk packaging. Original packaging specifications for the D4GL-2FFA-A are not provided in the reference data.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2FFA-D and D4SL-N2FFA-DN be used interchangeably with D4GL-2FFA-A?

A: Both substitute parts maintain identical circuit configuration (3PST-2NC/1NO + DPST-NC), actuator type (panel disconnect), termination style (screw terminal), conduit thread size (G1/2), operating temperature range (-10°C to 55°C), and ingress protection (IP67). Substitution is mechanically and functionally compatible. Electrical supply voltage differs (120VAC / 125VDC versus 240VAC), requiring circuit evaluation before implementation.

Q: What are the key differences between D4SL-N2FFA-D and D4SL-N2FFA-DN?

A: Both parts are identical in electrical specifications, mechanical configuration, and performance parameters. The designation suffix (-D versus -DN) reflects packaging or internal manufacturing variants. Both are active products with equivalent availability and support status.

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

A: Product status reflects manufacturer discontinuation. The D4SL-N series represents the current active equivalent line from Omron Automation and Safety, providing enhanced regulatory compliance and continued manufacturing support.

Q: Are the substitute parts rated for the same current as the original?

A: No. The D4GL-2FFA-A is rated at 750mA (AC) at 240VAC. The D4SL-N2FFA-D and D4SL-N2FFA-DN are rated at 1.5A (AC) at 120VAC and 220mA (DC) at 125VDC. Applications must confirm voltage supply compatibility before substitution.

Q: Do the substitute parts have the same holding force?

A: No. The D4GL-2FFA-A provides 102kgf holding force. The D4SL-N2FFA-D and D4SL-N2FFA-DN provide 133kgf holding force, representing a 31% increase in mechanical holding capacity.

Q: What regulatory approvals apply to the substitute parts?

A: D4SL-N2FFA-D and D4SL-N2FFA-DN carry CCC, CE, cURus, and TUV approvals. The original D4GL-2FFA-A carries CE, cULus, and TUV approvals. Substitute parts provide broader international compliance coverage.
