Substitute Part Grouping Explanation

The D4SL-N4RFA-D4 qualifies as a direct substitute based on the following criteria:

• Shared manufacturer: Omron Automation and Safety
• Shared base series: D4SL platform
• Active product status: D4SL-N4RFA-D4 is currently active, enabling procurement continuity
• Equivalent moisture sensitivity classification: MSL 1 (Unlimited)
• Regulatory alignment: Both parts carry compliance certifications appropriate for industrial switching applications

The substitution is valid within the D4SL product family architecture, where variants share common mechanical and electrical interfaces while differing in specific circuit configurations and actuator types.

Parameter Comparison

Engineering Selection Recommendations

The D4SL-N4RFA-D4 is the designated substitute for the obsolete D4SL-4RDA-D4. Selection is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Shared manufacturer platform reducing integration risk
• RoHS compliance of the substitute part meeting current regulatory requirements
• Multi-agency certifications (CCC, CE, cURus, TUV) providing broad market acceptance
• Equivalent moisture sensitivity classification maintaining environmental performance characteristics

Procurement of D4SL-N4RFA-D4 is appropriate for applications previously specified with D4SL-4RDA-D4, provided the electrical parameters (3PST-NC x 2 circuit, 1.5A AC / 220mA DC, 120VAC / 125VDC rating, 24VDC supply) align with system requirements.

Frequently Asked Questions (FAQ)

Q: Why is the D4SL-4RDA-D4 no longer available? A: The D4SL-4RDA-D4 has reached end-of-life status and is classified as obsolete. Omron Automation and Safety has transitioned this product line to active variants within the D4SL series.

Q: Is the D4SL-N4RFA-D4 a direct replacement? A: The D4SL-N4RFA-D4 is a substitute within the same D4SL product family. Both parts share the same manufacturer, base series designation, and moisture sensitivity classification. Verify that the electrical specifications (3PST-NC x 2 circuit, current and voltage ratings) match your application requirements.

Q: What are the key electrical differences between these parts? A: The D4SL-N4RFA-D4 specifies 3PST-NC x 2 circuit configuration, 1.5A AC current rating, 220mA DC current rating, 120VAC / 125VDC voltage rating, and 24VDC supply voltage. The D4SL-4RDA-D4 electrical specifications were not provided in available documentation.

Q: Does the substitute part meet current compliance standards? A: Yes. The D4SL-N4RFA-D4 is RoHS compliant and carries certifications from CCC, CE, cURus, and TUV, meeting current regulatory requirements for industrial switching applications.

Q: Are there packaging differences? A: Both parts are supplied in bulk packaging, maintaining consistency in procurement and handling procedures.

Q: What is the moisture sensitivity level for both parts? A: Both the D4SL-4RDA-D4 and D4SL-N4RFA-D4 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.
