Substitute Part Grouping Explanation

Substitute parts for the D4GL-4CFA-A4 are identified from the D4SL-N series, which maintains functional equivalence based on the following criteria:

Common Parameters (Substitution Basis):

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Release
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Actuator Type: Panel Disconnect
• Conduit Thread Size: M20
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67 - Dust Tight, Waterproof
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute Parts Identified:

1. D4SL-N4CFA (Active status, screw terminal)
2. D4SL-N4CFA-N (Active status, connector termination)

Both substitute parts are from the active D4SL-N series and share the core functional characteristics and environmental specifications of the obsolete D4GL-4CFA-A4.

Parameter Comparison

Engineering Selection Recommendations

The D4GL-4CFA-A4 is obsolete and no longer in active production. The D4SL-N series provides functional equivalents with active product status and current manufacturing support.

D4SL-N4CFA is the primary substitute when screw terminal connections are required. This part maintains the same termination style as the original D4GL-4CFA-A4 and is suitable for direct replacement in applications where screw-based wiring is specified.

D4SL-N4CFA-N is the alternative substitute when connector-based termination is acceptable or preferred. This variant offers the same functional performance with connector-style connections, which may simplify installation and maintenance procedures.

Both substitute parts carry expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the original part, ensuring compliance with current international standards. The D4SL-N series is actively manufactured and supported by Omron Automation and Safety.

Note that the D4SL-N series operates at lower voltage ratings (120VAC, 125VDC) and reduced holding force (6kgf) compared to the D4GL-4CFA-A4 (240VAC, 102kgf). Application-specific electrical and mechanical requirements must be evaluated before final part selection.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4CFA and D4SL-N4CFA-N be used interchangeably?

A: Both parts share identical electrical and mechanical specifications. The only difference is termination style: D4SL-N4CFA uses screw terminals, while D4SL-N4CFA-N uses connector termination. Selection depends on the wiring method required by your application.

Q: What are the key differences between the D4GL-4CFA-A4 and D4SL-N substitutes?

A: The primary differences are voltage rating (240VAC vs. 120VAC) and holding force (102kgf vs. 6kgf). Both maintain identical circuit configuration, actuator type, conduit thread size, operating temperature range, and IP67 ingress protection. Verify that your application can operate within the D4SL-N electrical and mechanical specifications.

Q: Why is the D4GL-4CFA-A4 classified as obsolete?

A: The D4GL-4CFA-A4 has been discontinued by Omron Automation and Safety. The D4SL-N series represents the current active product line for equivalent solenoid release functionality.

Q: Are the substitute parts certified to the same standards?

A: The D4SL-N series carries certifications from CCC, CE, cURus, and TUV, which includes all certifications held by the original D4GL-4CFA-A4 (CE, cULus, TUV). The expanded certification list reflects current regulatory requirements.

Q: What is the impact of reduced holding force in the D4SL-N series?

A: The D4SL-N series provides 6kgf holding force compared to 102kgf in the D4GL-4CFA-A4. This reduction is significant and must be evaluated against your application's mechanical requirements. If high holding force is critical, alternative solutions outside the D4SL-N series may be necessary.

Q: Can I use D4SL-N parts in a 240VAC system designed for the D4GL-4CFA-A4?

A: No. The D4SL-N series is rated for 120VAC maximum. Direct substitution in a 240VAC system is not permitted. System redesign or alternative parts must be considered.
