Key Parameters

Substitute Part Grouping Explanation

Substitution for the D4GL-1AFA-A4 is based on the following electrical and mechanical parameters:

Circuit configuration must remain DPST-NO/NC (DB/DM) x 2 to maintain functional compatibility with existing control logic. Actuator type must be Panel Disconnect to ensure mechanical fit and operational purpose. Operating temperature range must encompass or match the original specification (-10°C ~ 55°C). Ingress protection must maintain IP67 rating for environmental sealing. Approval agencies must include CE and TUV certifications for regulatory compliance.

The substitute parts D4SL-N4AFA and D4SL-N4AFA-N share identical circuit configuration, actuator type, operating temperature range, ingress protection rating, and core approval certifications. Both are active products from Omron Automation and Safety, ensuring long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

Both D4SL-N4AFA and D4SL-N4AFA-N are suitable replacements for the obsolete D4GL-1AFA-A4 based on product status and compliance certifications. The D4SL-N series is actively manufactured and supported by Omron Automation and Safety, ensuring component availability and technical documentation continuity.

The primary distinction between the two substitute parts is termination style: D4SL-N4AFA uses screw terminals matching the original D4GL-1AFA-A4 configuration, while D4SL-N4AFA-N uses connector termination. Selection between these options depends on existing wiring infrastructure and installation requirements.

Both substitute parts carry expanded approval certifications (CCC, CE, cURus, TUV) compared to the original part, providing broader regulatory compliance for international applications.

Frequently Asked Questions (FAQ)

Q: Can D4SL-N4AFA or D4SL-N4AFA-N be used as direct replacements for D4GL-1AFA-A4?

A: Yes. Both parts maintain identical circuit configuration (DPST-NO/NC x 2), actuator type (Panel Disconnect), operating temperature range (-10°C ~ 55°C), ingress protection (IP67), and core approval certifications (CE, TUV). These parameters define functional and environmental compatibility.

Q: What is the difference between D4SL-N4AFA and D4SL-N4AFA-N?

A: The parts are electrically and mechanically identical except for termination style. D4SL-N4AFA provides screw terminals; D4SL-N4AFA-N provides connector termination. Choose based on your existing wiring configuration.

Q: Why does the D4GL-1AFA-A4 show as obsolete?

A: The D4GL series has been superseded by the D4SL-N series. Omron continues to support the D4SL-N line as the current product offering for this application category.

Q: Are there voltage or current rating differences between the original and substitute parts?

A: Yes. The D4GL-1AFA-A4 operates at 240VAC with 750mA AC current rating and 102kgf holding force. The D4SL-N series operates at 120VAC/125VDC with 1.5A AC and 220mA DC current ratings and 6kgf holding force. Verify that your system design accommodates these electrical parameter differences before implementation.

Q: Do the substitute parts carry the same certifications?

A: The substitute parts carry expanded certifications. D4GL-1AFA-A4 holds CE, cULus, and TUV approvals. D4SL-N4AFA and D4SL-N4AFA-N hold CCC, CE, cURus, and TUV approvals, providing broader regulatory coverage.
