D4GL-4GFA-A4 Equivalent & Substitute Parts

Part Overview

The D4GL-4GFA-A4 is an interlock solenoid release manufactured by Omron Automation and Safety, configured as a 3PST switch with integrated status indicator and panel disconnect actuator. This part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity. The D4GL series has been superseded by the D4SL-N series, which maintains functional compatibility while offering extended operational parameters and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-4GFA-A4 is based on the following critical parameters that must remain consistent:

• Circuit configuration: 3PST-NC + DPST-NO/NC
• Actuator type: Panel Disconnect
• Conduit thread size: M20
• Ingress protection: IP67
• Operating temperature range: -10°C ~ 55°C
• Status indicator feature presence

The D4SL-N series satisfies these core functional requirements. Two variants are identified as substitutes:

1. D4SL-N4GFA-D4: Active product with screw terminal termination, matching the original termination style
2. D4SL-N4GFA-D4N: Active product with connector termination, offering alternative connection methodology

Both substitutes maintain the required circuit topology, environmental protection rating, and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4GFA-D4 is the primary substitute for direct replacement applications requiring screw terminal connectivity. This variant maintains active product status with Omron, ensuring long-term availability and support. The increased holding force (133kgf vs. 102kgf) and expanded current rating (1.5A AC vs. 750mA AC) provide enhanced operational margin. Regulatory compliance includes CCC, CE, cURus, and TUV certifications, extending the approval scope beyond the original part.

D4SL-N4GFA-D4N serves applications where connector-based termination is preferred or required by system architecture. This variant also maintains active product status and equivalent regulatory certifications. The reduced holding force (6kgf) indicates a different mechanical design intent; selection of this variant requires confirmation that the lower holding force is compatible with the application's force requirements.

Both substitutes are manufactured by the same supplier, ensuring consistency in quality and support protocols. The transition from D4GL to D4SL-N series represents a product line evolution rather than a functional discontinuity.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4GFA-D4 and D4SL-N4GFA-D4N be used interchangeably?

A: Both parts maintain identical circuit configuration, environmental protection, and mechanical interface specifications. The primary differences are termination style (screw terminal vs. connector) and holding force (133kgf vs. 6kgf). Selection depends on the specific termination requirement and force specification of the application.

Q: What is the impact of the holding force difference between D4GL-4GFA-A4 (102kgf) and D4SL-N4GFA-D4 (133kgf)?

A: The D4SL-N4GFA-D4 provides increased holding force, which is compatible with applications requiring the original 102kgf specification. Applications must not rely on the lower holding force of D4SL-N4GFA-D4N (6kgf) unless the system design has been verified for this reduced value.

Q: Are the voltage and current ratings of the D4SL-N series compatible with D4GL-4GFA-A4 applications?

A: The D4SL-N series operates at different nominal voltages (120VAC/125VDC vs. 240VAC/24VDC). System integration requires verification that the substitute part's electrical specifications align with the control circuit design. The D4SL-N4GFA-D4N explicitly specifies 24VDC supply voltage, matching the original part.

Q: What regulatory certifications should be considered when selecting a substitute?

A: The original D4GL-4GFA-A4 carries CE, cULus, and TUV approvals. Both D4SL-N substitutes include CCC, CE, cURus, and TUV certifications. The expanded certification scope of the D4SL-N series may provide additional compliance benefits for certain markets or applications.

Q: Is the D4GL-4GFA-A4 still available for procurement?

A: The D4GL-4GFA-A4 is classified as obsolete. Current inventory of 618 pieces is available through existing stock channels, but long-term availability cannot be assured. Transition to active D4SL-N series variants is recommended for new designs and future procurement planning.
