D4SL-2QDG-DN Equivalent & Substitute Parts

Part Overview

The D4SL-2QDG-DN is an Omron Automation and Safety snap action switch classified as obsolete. This component is no longer in active production, making identification of suitable substitute parts essential for system maintenance, repair, and component sourcing. The availability of 690 pieces in current inventory does not alter the obsolete status, necessitating qualified alternatives for long-term application support.

Substitute Part Grouping Explanation

The D4SL-2QDG-DN has one qualified substitute within the Omron D4SL product family: the D4SL-N2QFG-DN. Substitution eligibility is determined by the following criteria:

• Manufacturer alignment: Both parts are manufactured by Omron Automation and Safety
• Series compatibility: Both belong to the D4SL product line
• Moisture sensitivity classification: Both maintain MSL 1 (Unlimited)
• Regulatory compliance: Both carry equivalent international certifications (CCC, CE, cURus, TUV)

The D4SL-N2QFG-DN represents an active product status alternative, ensuring continued availability and manufacturer support for future procurement cycles.

Parameter Comparison

Engineering Selection Recommendations

Selection between the D4SL-2QDG-DN and D4SL-N2QFG-DN must account for the following factors:

Product Status Consideration: The D4SL-2QDG-DN is classified as obsolete. While current inventory exists, future procurement cannot be guaranteed. The D4SL-N2QFG-DN maintains active product status with manufacturer support.

Compliance and Certification: The D4SL-N2QFG-DN carries documented international certifications (CCC, CE, cURus, TUV) and holds EAR99 export classification. The D4SL-2QDG-DN certification details are not provided.

Moisture Sensitivity: Both parts maintain identical MSL 1 classification, indicating no moisture sensitivity constraints for either component.

Electrical and Mechanical Specifications: The D4SL-N2QFG-DN provides complete electrical ratings (1.5A AC, 220mA DC), voltage specifications (120VAC, 125VDC, 24VDC supply), and mechanical parameters (6kgf holding force, IP67 ingress protection). The D4SL-2QDG-DN specifications are not provided in available documentation.

For new designs or long-term system support, the D4SL-N2QFG-DN is the appropriate selection. For existing systems currently using D4SL-2QDG-DN components, substitution feasibility depends on application-specific electrical and mechanical requirements that must be verified against the D4SL-N2QFG-DN specifications.

Frequently Asked Questions (FAQ)

Q: Can the D4SL-N2QFG-DN directly replace the D4SL-2QDG-DN in existing applications?

A: Direct substitution requires verification that the D4SL-N2QFG-DN electrical ratings (1.5A AC, 220mA DC, 120VAC/125VDC/24VDC), circuit configuration (3PST-2NC/1NO + 3PST-NC), and mechanical specifications (6kgf holding force, panel disconnect actuator, connector termination) are compatible with the original application requirements. The D4SL-2QDG-DN specifications are not fully documented, making compatibility assessment dependent on application parameters.

Q: Why is the D4SL-2QDG-DN classified as obsolete?

A: Omron Automation and Safety has discontinued production of the D4SL-2QDG-DN. Obsolete classification indicates the part is no longer manufactured or supported by the vendor. Current inventory availability does not change this status.

Q: What is the difference between the D4SL-2QDG-DN and D4SL-N2QFG-DN product types?

A: The D4SL-2QDG-DN is classified as a snap action switch. The D4SL-N2QFG-DN is a solenoid locking interlock switch with 3PST circuit configuration. These represent different functional categories within the D4SL product family.

Q: Are both parts available for immediate procurement?

A: Current inventory records indicate 690 pieces of D4SL-2QDG-DN and 826 pieces of D4SL-N2QFG-DN are in stock. However, the D4SL-2QDG-DN is obsolete and future availability cannot be guaranteed. The D4SL-N2QFG-DN maintains active product status.

Q: What certifications apply to the D4SL-N2QFG-DN?

A: The D4SL-N2QFG-DN holds CCC, CE, cURus, and TUV certifications. It is classified as EAR99 for export purposes.

Q: What is the packaging format for the D4SL-N2QFG-DN?

A: The D4SL-N2QFG-DN is supplied in bulk packaging. The D4SL-2QDG-DN packaging format is not specified in available documentation.
