Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-2BFA-A is based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Manufacturer: Omron Automation and Safety
• Type: Solenoid Release
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Actuator Type: Panel Disconnect
• Conduit Thread Size: G1/2
• Operating Temperature Range: -10°C ~ 55°C
• Ingress Protection: IP67
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Current Rating: Substitute parts may have different AC/DC current ratings provided they meet or exceed the application requirements
• Voltage Rating: Substitute parts may operate at different voltage levels (120VAC/125VDC vs. 240VAC/24VDC) depending on system design
• Holding Force: Substitute parts may have different holding force values (6kgf vs. 102kgf) based on application load requirements
• Termination Style: Screw Terminal or Connector options are both acceptable
• Product Status: Active status substitutes are preferred for obsolete parts

The D4SL-N series parts meet all mandatory matching parameters and are classified as active products, making them suitable substitutes for the obsolete D4GL-2BFA-A.

Parameter Comparison

Engineering Selection Recommendations

D4SL-N2BFA (Screw Terminal Configuration)

This substitute is suitable for applications requiring screw terminal connections. Both the D4GL-2BFA-A and D4SL-N2BFA maintain identical termination style, simplifying installation in existing harnesses. The D4SL-N2BFA carries active product status with expanded approval certifications (CCC, CE, cURus, TUV), providing superior long-term availability and support compared to the obsolete D4GL-2BFA-A.

D4SL-N2BFA-N (Connector Configuration)

This substitute is appropriate for applications where connector-based termination is preferred or required. The connector interface offers advantages in modularity and field replacement scenarios. Like the D4SL-N2BFA, this part maintains active product status and expanded regulatory approvals.

Voltage and Current Considerations

The D4SL-N series operates at 120VAC/125VDC with current ratings of 1.5A (AC) and 220mA (DC), differing from the D4GL-2BFA-A specifications of 240VAC at 750mA. System design must accommodate these electrical parameter differences. The D4SL-N series provides higher AC current capacity (1.5A vs. 750mA), making it suitable for applications with increased current demands.

Holding Force Difference

The D4SL-N series provides 6kgf holding force compared to the D4GL-2BFA-A at 102kgf. Applications requiring the higher holding force of the original part may require mechanical redesign or alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2BFA or D4SL-N2BFA-N directly replace D4GL-2BFA-A without modification?

A: Direct replacement requires verification of system voltage and current requirements. The D4SL-N series operates at different voltage levels (120VAC/125VDC) and current ratings (1.5A AC, 220mA DC) than the original part (240VAC, 750mA). Additionally, the holding force differs significantly (6kgf vs. 102kgf). System design must accommodate these parameter differences.

Q: What is the primary difference between D4SL-N2BFA and D4SL-N2BFA-N?

A: The primary difference is termination style. D4SL-N2BFA uses screw terminals, while D4SL-N2BFA-N uses a connector interface. All other electrical and mechanical parameters are identical. Selection depends on installation requirements and existing harness configuration.

Q: Why is the D4GL-2BFA-A obsolete?

A: Product obsolescence is determined by the manufacturer. The D4SL-N series represents the current active equivalent from Omron Automation and Safety for this solenoid release function.

Q: Are the approval certifications compatible between D4GL-2BFA-A and D4SL-N substitutes?

A: The D4GL-2BFA-A carries CE, cULus, and TUV certifications. The D4SL-N series carries CCC, CE, cURus, and TUV certifications. The D4SL-N series provides expanded regulatory coverage, including CCC certification not present on the original part.

Q: What is the holding force difference, and does it affect substitution?

A: The D4GL-2BFA-A provides 102kgf holding force, while D4SL-N series provides 6kgf. This significant difference means applications dependent on the higher holding force require evaluation of mechanical load requirements and potential system redesign.

Q: Are both substitute parts in stock?

A: Yes. D4SL-N2BFA inventory: 790 Pcs. D4SL-N2BFA-N inventory: 1005 Pcs. Both are available as new original stock.
