SG-A1-02-1 Equivalent & Substitute Parts

Part Overview

The SG-A1-02-1 is a non-locking interlock DPST switch manufactured by Panasonic Industrial Automation Sales. This panel disconnect switch operates at 2.5A (AC/DC) with voltage ratings of 125VAC and 30VDC, featuring IP67 ingress protection and cable lead termination with 1m cable length. The product is active and RoHS compliant with CE, cULus, and TUV approvals. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of this product category.

Substitute Part Grouping Explanation

Substitute parts for the SG-A1-02-1 are identified based on the following critical parameters that define functional equivalence within the interlock non-locking DPST switch category:

Primary Substitution Criteria:

• Circuit configuration: DPST-NC
• Type: Non-Locking
• Actuator type: Panel Disconnect
• Termination style: Cable Leads
• Ingress protection: IP67
• Operating temperature range compatibility
• Regulatory compliance: CE, cULus, TUV certifications

The identified substitutes (D4GS-N2T and D4GS-N2T-5) maintain the same circuit configuration, actuator type, termination style, and ingress protection rating. Both are manufactured by Omron Automation and Safety and carry equivalent regulatory approvals. The primary distinction between substitute options relates to cable length specification and current rating capacity.

Parameter Comparison

Engineering Selection Recommendations

Both D4GS-N2T and D4GS-N2T-5 are active products with regulatory compliance exceeding the original SG-A1-02-1 specification. The Omron substitutes carry CCC certification in addition to CE, cULus, and TUV approvals. Both substitute parts maintain ROHS3 compliance and achieve the same IP67 ingress protection rating.

Selection between substitute options depends on cable length requirements: D4GS-N2T provides 1m cable length matching the original specification, while D4GS-N2T-5 provides extended 5m cable length for applications requiring greater lead distance.

Current rating differences exist between the main part and substitutes. The SG-A1-02-1 is rated for 2.5A (AC/DC), while both Omron substitutes are rated for 750mA (AC). Voltage rating differences also exist: the SG-A1-02-1 operates at 125VAC and 30VDC, while the Omron substitutes operate at 240VAC. These electrical parameter differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: What defines functional equivalence for the SG-A1-02-1 substitute parts?

A: Functional equivalence is established through matching circuit configuration (DPST-NC), switch type (non-locking), actuator type (panel disconnect), termination style (cable leads), and ingress protection rating (IP67). All identified substitutes meet these core criteria.

Q: How do current ratings affect part selection?

A: The SG-A1-02-1 is rated for 2.5A (AC/DC), while the Omron substitutes are rated for 750mA (AC). Applications requiring currents above 750mA cannot use the Omron substitutes. Current rating must be evaluated against specific circuit requirements.

Q: What is the difference between D4GS-N2T and D4GS-N2T-5?

A: Both parts are electrically identical Omron DPST-NC non-locking interlock switches. The primary difference is cable length: D4GS-N2T provides 1m cable length, while D4GS-N2T-5 provides 5m cable length. Selection depends on installation distance requirements.

Q: Are the voltage ratings compatible with the original application?

A: The SG-A1-02-1 operates at 125VAC and 30VDC. The Omron substitutes operate at 240VAC. Voltage compatibility must be confirmed against the specific application circuit before substitution.

Q: What regulatory approvals do the substitute parts carry?

A: Both D4GS-N2T and D4GS-N2T-5 carry CCC, CE, cULus, and TUV approvals, exceeding the original SG-A1-02-1 certification set (CE, cULus, TUV). Both are ROHS3 compliant.

Q: What is the operating temperature range for substitute parts?

A: Both Omron substitutes operate across -30°C to 70°C, providing a 5°C lower minimum temperature limit compared to the SG-A1-02-1 (-25°C to 70°C).
