Omron D4GL-2AFA-A Interlock Solenoid Release DPST - Equivalent & Substitute Parts

Part Overview

The Omron D4GL-2AFA-A is an interlock solenoid release switch designed for panel disconnect applications with dual-pole, single-throw (DPST) configuration. This component operates at 240VAC with 24VDC supply voltage and provides a holding force of 102kgf. The D4GL-2AFA-A is classified as obsolete, making identification of active equivalent parts essential for system maintenance, repair, and new design implementations where functional compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D4GL-2AFA-A is based on functional equivalence within the Omron solenoid release product family. The substitute parts identified are from the D4SL-N series, which maintains the same circuit configuration (DPST-NO/NC), actuator type (Panel Disconnect), conduit thread size (G1/2), operating temperature range (-10°C to 55°C), ingress protection rating (IP67), and moisture sensitivity level (MSL 1).

The D4SL-N series represents the active product line replacement for the obsolete D4GL series. Both substitute parts—D4SL-N2AFA and D4SL-N2AFA-N—share identical electrical and mechanical specifications with the following exceptions:

Current Rating: D4SL-N series rated at 1.5A (AC) and 220mA (DC), compared to D4GL-2AFA-A at 750mA (AC)

Voltage Rating: D4SL-N series operates at 120VAC and 125VDC, whereas D4GL-2AFA-A operates at 240VAC and 24VDC

Holding Force: D4SL-N series provides 6kgf holding force versus 102kgf for D4GL-2AFA-A

Termination Style: D4SL-N2AFA uses Screw Terminal (matching D4GL-2AFA-A), while D4SL-N2AFA-N uses Connector termination

The key differentiator between the two D4SL-N substitutes is termination style. Selection between D4SL-N2AFA and D4SL-N2AFA-N depends on whether screw terminal or connector-based integration is required in the target application.

Parameter Comparison

Engineering Selection Recommendations

Selection between D4SL-N2AFA and D4SL-N2AFA-N should be based on termination requirements and system integration approach. D4SL-N2AFA is appropriate for applications requiring screw terminal connections, maintaining direct compatibility with existing wiring harnesses designed for the D4GL-2AFA-A. D4SL-N2AFA-N is suitable for connector-based integration, offering simplified assembly and potential for standardized connector interfaces in modern panel designs.

Both D4SL-N variants carry active product status with expanded regulatory approvals (CCC, CE, cURus, TUV) compared to the obsolete D4GL-2AFA-A (CE, cULus, TUV). This expanded certification profile supports deployment in broader geographic and regulatory markets.

Critical consideration: The D4SL-N series exhibits reduced holding force (6kgf versus 102kgf) and operates at lower voltage ratings (120VAC/125VDC versus 240VAC/24VDC). Applications dependent on the higher holding force specification of the D4GL-2AFA-A require engineering evaluation to confirm that the D4SL-N series mechanical performance is adequate for the intended load conditions.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N2AFA and D4SL-N2AFA-N be used interchangeably?

A: Both parts share identical electrical and mechanical specifications. The only difference is termination style: D4SL-N2AFA uses screw terminals while D4SL-N2AFA-N uses connector termination. Selection depends on the connection method required by your application. They cannot be physically interchanged without rewiring or adapter modifications.

Q: What is the primary difference between the D4GL-2AFA-A and D4SL-N series?

A: The D4GL-2AFA-A is obsolete, while D4SL-N variants are active products. The D4SL-N series operates at lower voltage ratings (120VAC/125VDC versus 240VAC/24VDC), carries higher AC current capacity (1.5A versus 750mA), and provides lower holding force (6kgf versus 102kgf). Both maintain identical circuit configuration, actuator type, and environmental protection ratings.

Q: Are there holding force implications when substituting the D4GL-2AFA-A?

A: Yes. The D4GL-2AFA-A provides 102kgf holding force, while D4SL-N substitutes provide 6kgf. Applications where the higher holding force is critical to system operation require engineering assessment to confirm the D4SL-N series is mechanically adequate for the intended load.

Q: Do the substitute parts have the same regulatory approvals?

A: The D4SL-N series carries expanded approvals (CCC, CE, cURus, TUV) compared to the D4GL-2AFA-A (CE, cULus, TUV). This broader certification profile supports compliance in additional regulatory jurisdictions.

Q: Which substitute part should I select for a direct replacement?

A: D4SL-N2AFA is the direct replacement if your application uses screw terminal connections. D4SL-N2AFA-N is appropriate if connector-based termination is preferred or required by your system design.
