Omron D4GL-4BFA-A4 Interlock Solenoid Release DPST - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-4BFA-A4 is an interlock solenoid release switch with dual-pole, single-throw (DPST) configuration designed for panel disconnect applications. This component features a 24VDC supply voltage, 240VAC switching capability, and 102kgf holding force. The part is classified as obsolete, making identification of functionally equivalent active alternatives essential for system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The D4GL-4BFA-A4 has been superseded by the D4SL-N series from Omron. Substitution eligibility is determined by the following parameters:

• Circuit configuration: DPST-NO/NC + DPST-NC (maintained across all alternatives)
• Actuator type: Panel Disconnect (consistent across substitutes)
• Conduit thread size: M20 (standardized)
• Operating temperature range: -10°C ~ 55°C (maintained)
• Ingress protection: IP67 (maintained)
• Termination style compatibility: Screw Terminal or Connector options available

The D4SL-N series represents the active product line replacement. Two variants are available, differentiated by termination style: screw terminal (D4SL-N4BFA) and connector (D4SL-N4BFA-N).

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4BFA and D4SL-N4BFA-N are active products from Omron and represent the current generation replacement for the obsolete D4GL-4BFA-A4. Selection between the two substitutes depends on termination requirements:

• D4SL-N4BFA: Select for applications requiring screw terminal connections, matching the original part's termination style.
• D4SL-N4BFA-N: Select for applications requiring connector-based termination.

Both substitutes maintain the same circuit configuration, actuator type, conduit thread size, operating temperature range, and ingress protection rating as the original part. Regulatory compliance is enhanced in the D4SL-N series, which includes CCC certification in addition to CE, cURus, and TUV approvals.

Note that the D4SL-N series exhibits lower holding force (6kgf versus 102kgf) and different voltage/current ratings compared to the D4GL-4BFA-A4. These parameter differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4BFA or D4SL-N4BFA-N be used as direct replacements for D4GL-4BFA-A4?

A: Both D4SL-N variants maintain the same circuit configuration (DPST-NO/NC + DPST-NC), actuator type (Panel Disconnect), conduit thread size (M20), operating temperature range, and ingress protection rating. However, holding force and voltage/current ratings differ. Application-specific requirements must be evaluated before substitution.

Q: What is the difference between D4SL-N4BFA and D4SL-N4BFA-N?

A: The primary difference is termination style. D4SL-N4BFA uses screw terminals, while D4SL-N4BFA-N uses connector termination. Both are functionally equivalent in all other parameters.

Q: Why does the D4SL-N series have lower holding force than the D4GL-4BFA-A4?

A: The D4SL-N series is a different product line within Omron's solenoid release portfolio. Holding force is a design characteristic specific to each series and application class.

Q: Are the voltage and current ratings compatible between the original and substitute parts?

A: The D4GL-4BFA-A4 operates at 240VAC with 750mA AC current and 24VDC supply. The D4SL-N series operates at 120VAC/125VDC with 1.5A AC and 220mA DC ratings. These differences require circuit evaluation for compatibility.

Q: What certifications do the substitute parts carry?

A: Both D4SL-N4BFA and D4SL-N4BFA-N carry CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage than the original D4GL-4BFA-A4 (CE, cULus, TUV).
