Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration: 3PST-NC + DPST-NO/NC
• Voltage supply: 24VDC
• Actuator type: Panel Disconnect
• Conduit thread size: G1/2
• Operating temperature range: -10°C to 55°C
• Ingress protection: IP67
• Status indicator feature
• Manufacturer: Omron Automation and Safety

Substitute Parts Identified:

• D4SL-N2GFA-D (Screw Terminal variant)
• D4SL-N2GFA-DN (Connector variant)

Both substitute parts maintain the core circuit configuration, supply voltage, actuator type, environmental protection rating, and operating temperature range of the original D4GL-2GFA-A. The D4SL-N series represents the active product line continuation with equivalent functional specifications. Differences in current rating and holding force reflect design improvements in the active product line while maintaining circuit-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2GFA-D Selection Criteria: The D4SL-N2GFA-D maintains screw terminal connectivity identical to the D4GL-2GFA-A, providing direct mechanical and electrical interface compatibility. This variant is recommended for applications where existing wiring harnesses and terminal block configurations are designed for screw terminal connections. The part holds active product status with current manufacturing support and expanded regulatory approvals including CCC certification.

D4SL-N2GFA-DN Selection Criteria: The D4SL-N2GFA-DN features connector-based termination, requiring interface adaptation from the original screw terminal design. This variant is appropriate for applications undergoing modernization or where connector-based termination provides installation advantages. The part maintains active product status with equivalent regulatory compliance.

Regulatory Compliance: Both substitute parts maintain CE and TUV certifications present in the original D4GL-2GFA-A. The D4SL-N series adds CCC certification, expanding compliance scope. The original cULus certification is superseded by cURus certification in the substitute parts, representing updated UL/CSA approval standards.

Product Availability: The D4GL-2GFA-A is obsolete with no ongoing manufacturing. The D4SL-N2GFA-D and D4SL-N2GFA-DN are active products with documented inventory availability, ensuring reliable sourcing for replacement and new applications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2GFA-D and D4SL-N2GFA-DN be used interchangeably with D4GL-2GFA-A?

A: Both D4SL-N series parts maintain identical circuit configuration (3PST-NC + DPST-NO/NC), supply voltage (24VDC), actuator type (Panel Disconnect), and environmental specifications (IP67, -10°C to 55°C). The primary difference is termination style: D4SL-N2GFA-D uses screw terminals matching the original, while D4SL-N2GFA-DN uses connector termination. Selection depends on existing installation requirements.

Q: What is the difference between D4SL-N2GFA-D and D4SL-N2GFA-DN?

A: The parts are functionally identical except for termination style. D4SL-N2GFA-D provides screw terminal connections for direct replacement in existing installations. D4SL-N2GFA-DN provides connector-based termination, requiring interface adaptation but offering advantages in modular installation approaches.

Q: Are the current ratings of substitute parts compatible with D4GL-2GFA-A applications?

A: The D4SL-N series parts are rated for 1.5A AC and 220mA DC, compared to the D4GL-2GFA-A rating of 750mA AC. The higher AC current rating of substitute parts ensures compatibility with applications designed for the original 750mA specification. DC current capability is newly specified in the substitute parts.

Q: What regulatory certifications apply to substitute parts?

A: D4SL-N2GFA-D and D4SL-N2GFA-DN hold CCC, CE, cURus, and TUV certifications. The original D4GL-2GFA-A held CE, cULus, and TUV certifications. The cURus certification in substitute parts represents current UL/CSA approval standards superseding the original cULus designation.

Q: Is inventory availability different between substitute options?

A: D4SL-N2GFA-D has 1028 units in stock. D4SL-N2GFA-DN has 1042 units in stock. Both parts maintain active product status with consistent availability. The original D4GL-2GFA-A, though showing 657 units in stock, is obsolete and subject to depletion without replenishment.

Q: Can substitute parts be used in existing panel disconnect installations?

A: Yes. Both substitute parts maintain identical panel disconnect actuator type, G1/2 conduit thread size, and IP67 environmental protection. D4SL-N2GFA-D provides direct mechanical fit with screw terminal compatibility. D4SL-N2GFA-DN requires connector interface adaptation but maintains identical mounting and environmental specifications.
