Equivalent & Substitute Parts for D4GL-4CFA-A

Part Overview

The D4GL-4CFA-A is an interlock solenoid release switch manufactured by Omron Automation and Safety. This DPST (Double Pole Single Throw) component functions as a panel disconnect actuator with dual circuit configuration (DPST-NO/NC + DPST-NC), rated for 240VAC at 750mA with 24VDC supply voltage. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for continued system operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete D4GL-4CFA-A is evaluated based on the following critical parameters that define functional equivalence:

Mandatory Compatibility Criteria:

• Manufacturer: Omron Automation and Safety (same manufacturer ensures design continuity)
• Circuit Configuration: DPST-NO/NC + DPST-NC (identical switching logic)
• Actuator Type: Panel Disconnect (same mechanical interface)
• Conduit Thread Size: M20 (mechanical fit requirement)
• Operating Temperature Range: -10°C ~ 55°C (environmental tolerance)
• Ingress Protection: IP67 (sealing specification)

Electrical Parameter Considerations:

• Voltage Rating and Current Rating must support the application requirements
• Supply Voltage compatibility with system design
• Holding Force specifications must meet or exceed application demands

The D4SL-N series (D4SL-N4CFA and D4SL-N4CFA-N) are active Omron products that maintain identical circuit configuration, actuator type, mechanical dimensions, and environmental specifications. These parts are direct functional equivalents with updated product status and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N4CFA (Screw Terminal Configuration): This substitute maintains screw terminal termination identical to the D4GL-4CFA-A, providing direct mechanical compatibility with existing wiring harnesses. The part is active with current manufacturing support and carries expanded regulatory approvals (CCC, CE, cURus, TUV). Selection of this variant is appropriate when existing installation infrastructure utilizes screw terminal connections.

D4SL-N4CFA-N (Connector Configuration): This variant provides identical electrical and mechanical specifications with connector-based termination. The connector interface may require harness modification or adapter implementation depending on installation requirements. This configuration offers the same regulatory compliance and active product status as the screw terminal variant.

Critical Electrical Differences: The D4SL-N series operates at 120VAC/125VDC with 1.5A (AC) and 220mA (DC) ratings, compared to the D4GL-4CFA-A specification of 240VAC at 750mA (AC). Applications requiring 240VAC operation or higher current capacity must evaluate whether the reduced voltage and current specifications of the D4SL-N series are compatible with system design parameters. The holding force reduction from 102kgf to 6kgf represents a significant mechanical specification change that must be assessed against application force requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4CFA or D4SL-N4CFA-N directly replace D4GL-4CFA-A without modification?

A: Both D4SL-N variants maintain identical circuit configuration (DPST-NO/NC + DPST-NC), actuator type (Panel Disconnect), mechanical dimensions (M20 conduit thread), and environmental specifications (IP67, -10°C ~ 55°C). However, electrical specifications differ: the D4SL-N series operates at 120VAC/125VDC versus the D4GL-4CFA-A at 240VAC. Direct replacement is feasible only if the application system operates at 120VAC or 125VDC. The D4SL-N4CFA-N requires connector termination modification if the existing installation uses screw terminals.

Q: What is the difference between D4SL-N4CFA and D4SL-N4CFA-N?

A: Both parts are electrically and mechanically identical. The sole difference is termination style: D4SL-N4CFA uses screw terminals, while D4SL-N4CFA-N uses connector termination. Selection depends on the existing wiring interface in the installation.

Q: Why does the D4SL-N series have lower holding force (6kgf) compared to D4GL-4CFA-A (102kgf)?

A: The D4SL-N series represents a different product line within the Omron solenoid release portfolio, designed for applications with different force requirements. The holding force specification must be evaluated against the specific application load. If the application requires 102kgf holding force, the D4SL-N series is not suitable.

Q: Are the D4SL-N variants currently available?

A: Yes. Both D4SL-N4CFA and D4SL-N4CFA-N are classified as active products with current manufacturing support and documented inventory availability (715 and 748 units respectively).

Q: What regulatory approvals do the substitute parts carry?

A: The D4SL-N series carries CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the D4GL-4CFA-A (CE, cULus, TUV). Both variants meet the same moisture sensitivity level (MSL 1 - Unlimited).
