Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-1BFA-A is determined by the following critical parameters:

Functional Equivalence Criteria:

• Type: Solenoid Release
• Circuit Configuration: DPST-NO/NC + DPST-NC
• Actuator Type: Panel Disconnect
• Operating Temperature Range: -10°C to 55°C
• Ingress Protection: IP67
• Approval Agencies: CE, TUV (minimum common certifications)

Compatibility Considerations:

• Termination Style: Screw Terminal vs. Connector (affects installation method)
• Conduit Thread Size: PG14.6 vs. M20 (affects mechanical mounting)
• Holding Force: 102kgf vs. 6kgf (significant difference in mechanical capability)
• Current and Voltage Ratings: Different supply and load specifications

The D4SL-N series represents the active product line replacement for the obsolete D4GL series. Both D4SL-N4BFA and D4SL-N4BFA-N maintain identical electrical circuit configuration and environmental ratings. The primary distinction between substitute options is termination style: screw terminal versus connector-based connection.

Parameter Comparison

Engineering Selection Recommendations

For D4GL-1BFA-A Replacement:

The D4SL-N4BFA is the primary substitute when screw terminal connection is required. This part maintains identical termination style to the original component and is currently in active production status with full compliance certifications including CE, cURus, and TUV.

The D4SL-N4BFA-N serves as an alternative when connector-based termination is acceptable or preferred. This variant offers the same electrical and environmental specifications with connector termination, reducing installation time in applications where quick-disconnect capability is beneficial.

Compliance Considerations:

Both substitute parts carry expanded approval agency certifications (CCC addition) compared to the original D4GL-1BFA-A, ensuring broader regulatory acceptance. The transition from cULus to cURus certification reflects current industry standards.

Mechanical Compatibility:

Installation requires attention to conduit thread size differences. The D4GL-1BFA-A uses PG14.6 threading, while D4SL-N series components use M20 threading. Mechanical mounting adapters or panel modifications may be necessary depending on existing installation infrastructure.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4BFA and D4SL-N4BFA-N be used interchangeably?

A: Both parts are electrically and functionally identical. The difference is termination style: D4SL-N4BFA uses screw terminals while D4SL-N4BFA-N uses connector termination. Selection depends on your wiring infrastructure and installation requirements.

Q: What is the impact of the holding force difference between D4GL-1BFA-A (102kgf) and D4SL-N series (6kgf)?

A: The D4GL-1BFA-A provides significantly higher holding force. If your application requires the original 102kgf specification, the D4SL-N series may not be suitable. Verify your system's mechanical requirements before substitution.

Q: Are there voltage and current rating differences I should consider?

A: Yes. The D4GL-1BFA-A operates at 240VAC with 750mA current rating and 24VDC supply. The D4SL-N series operates at 120VAC/125VDC with 1.5A AC or 220mA DC ratings. Confirm your application's electrical specifications match the substitute part before implementation.

Q: What about the conduit thread size change from PG14.6 to M20?

A: This is a mechanical interface change. Your panel or enclosure mounting point must accommodate M20 threading, or mechanical adapters must be sourced. Verify your installation environment before selecting a substitute.

Q: Are both D4SL-N variants currently available?

A: Yes. D4SL-N4BFA has 1033 units in stock and D4SL-N4BFA-N has 918 units in stock, both classified as new original inventory.
