Key Parameters

Substitute Part Grouping Explanation

The Omron D4NS-4AF qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Circuit configuration: DPST-NO/NC
• Actuator type: Panel Disconnect
• Termination style: Screw Terminal
• Ingress protection: IP67 - Dust Tight, Waterproof
• Conduit thread size: M20
• Moisture sensitivity level: 1 (Unlimited)
• Approval agencies: CE, cULus (both present in D4NS-4AF certifications)

Differing Parameters:

• Current rating: T4012-011F1M-SC1 rated 4A (AC/DC); D4NS-4AF rated 3A (AC)
• Voltage rating: T4012-011F1M-SC1 rated 230VAC, 24VDC; D4NS-4AF rated 240VAC
• Holding force: T4012-011F1M-SC1 has 3kgf; D4NS-4AF has 6kgf
• Operating temperature: T4012-011F1M-SC1 range -20°C ~ 80°C; D4NS-4AF range -30°C ~ 70°C
• Product status: T4012-011F1M-SC1 is obsolete; D4NS-4AF is active

The D4NS-4AF represents an active product line with enhanced certifications (CCC, TUV added) and RoHS3 compliance, providing improved availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The D4NS-4AF serves as the active equivalent to the obsolete T4012-011F1M-SC1. Both components share identical circuit topology, actuator configuration, and environmental protection ratings. The D4NS-4AF is recommended for new designs and stock replenishment due to its active product status and expanded regulatory certifications (CCC, TUV).

Application Considerations: Applications operating at 4A DC or requiring the full -20°C to +80°C temperature range of the original T4012-011F1M-SC1 must evaluate the D4NS-4AF's 3A AC rating and -30°C to +70°C operating window. The D4NS-4AF's increased holding force (6kgf versus 3kgf) provides enhanced mechanical stability in panel disconnect applications.

Regulatory Compliance: The D4NS-4AF includes RoHS3 compliance and additional certifications (CCC, TUV) beyond the original part's CE and cULus approvals, supporting broader market deployment and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the D4NS-4AF directly replace the T4012-011F1M-SC1 in all applications? A: The D4NS-4AF is functionally equivalent for DPST-NO/NC panel disconnect switching with IP67 protection. However, applications requiring 4A DC operation or the full -20°C to +80°C temperature range must confirm the D4NS-4AF's 3A AC rating and -30°C to +70°C operating window are acceptable for the specific application.

Q: What is the significance of the higher holding force in the D4NS-4AF? A: The D4NS-4AF's 6kgf holding force compared to the T4012-011F1M-SC1's 3kgf provides increased mechanical retention in the panel disconnect actuator, reducing unintended actuation in high-vibration or high-shock environments.

Q: Are there packaging differences between these parts? A: The T4012-011F1M-SC1 packaging is not specified in available data. The D4NS-4AF is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: Why is the D4NS-4AF rated for 240VAC while the original is rated 230VAC? A: The D4NS-4AF's 240VAC rating encompasses the 230VAC operating point. This represents a standard voltage tolerance range in industrial control applications and does not restrict compatibility with 230VAC systems.

Q: What certifications should I prioritize for regulatory compliance? A: The D4NS-4AF includes CE and cULus certifications matching the original part, plus additional CCC and TUV approvals. Select based on your target market requirements: CE for European markets, cULus for North American markets, CCC for Chinese markets, and TUV for additional European and international recognition.
