SG-A1-03-5 Equivalent & Substitute Parts

Part Overview

The SG-A1-03-5 is a non-locking interlock switch manufactured by Panasonic Industrial Automation Sales. This 3PST-NC circuit switch is designed for panel disconnect applications with cable lead termination and a 5-meter cable length. The part operates across a voltage range of 125VAC and 30VDC with a current rating of 2.5A (AC/DC), meeting IP67 ingress protection standards for dust-tight and waterproof environments. The product maintains active status with full RoHS compliance and CE, cULus, and TUV certifications. Equivalent substitute parts may be required due to supply availability, regional sourcing preferences, or specific application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SG-A1-03-5 are identified based on strict equivalence of the following critical parameters:

• Circuit configuration: 3PST-NC (three-pole, single-throw, normally closed)
• Switch type: Non-locking interlock
• Actuator type: Panel disconnect
• Termination style: Cable leads
• Ingress protection: IP67 rating
• Operating temperature range compatibility
• Regulatory compliance: CE, cULus, TUV certifications

The substitute parts D4GS-N4T and D4GS-N4T-5 from Omron Automation and Safety meet these core functional requirements. Both parts maintain the same circuit configuration, non-locking type, panel disconnect actuator, cable lead termination, and IP67 ingress protection. The primary distinction between substitutes is cable length: D4GS-N4T provides 1-meter cable length, while D4GS-N4T-5 provides 5-meter cable length, matching the original SG-A1-03-5 specification.

Parameter Comparison

Engineering Selection Recommendations

The D4GS-N4T-5 from Omron Automation and Safety provides the closest functional equivalence to the SG-A1-03-5, matching the 5-meter cable length specification. Both parts maintain active product status with full regulatory compliance across CE, cULus, and TUV certifications. The D4GS-N4T-5 additionally carries CCC certification, extending compliance scope.

The D4GS-N4T variant offers identical electrical and mechanical characteristics to the D4GS-N4T-5 with the exception of cable length (1 meter versus 5 meters). This variant is suitable for applications where cable length requirements differ from the original specification.

Both Omron substitutes operate across an extended low-temperature range (-30°C versus -25°C), providing enhanced performance in cold environments. Current and voltage ratings differ between the original and substitute parts; applications must verify that the substitute ratings are adequate for the intended circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can D4GS-N4T-5 directly replace SG-A1-03-5 in all applications?

A: D4GS-N4T-5 maintains functional equivalence in circuit configuration (3PST-NC), switch type (non-locking), actuator type (panel disconnect), termination style (cable leads), and ingress protection (IP67). However, the current rating differs (750mA AC versus 2.5A AC/DC) and voltage rating differs (240VAC versus 125VAC, 30VDC). Verify that application requirements fall within the substitute part's electrical specifications before implementation.

Q: What is the difference between D4GS-N4T and D4GS-N4T-5?

A: Both parts are functionally identical Omron switches with matching electrical and mechanical specifications. The sole difference is cable length: D4GS-N4T provides 1-meter cable length, while D4GS-N4T-5 provides 5-meter cable length. Select based on cable routing requirements in your application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The SG-A1-03-5 is RoHS Compliant. D4GS-N4T-5 is RoHS Compliant. D4GS-N4T is RoHS3 Compliant. All parts meet RoHS requirements for hazardous substance restrictions.

Q: Do substitute parts carry the same certifications as the original?

A: Both Omron substitutes (D4GS-N4T and D4GS-N4T-5) carry CE, cULus, and TUV certifications matching the original SG-A1-03-5. Additionally, both Omron parts carry CCC certification, which the original does not list.

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

A: Both D4GS-N4T and D4GS-N4T-5 operate across -30°C to 70°C, compared to the original SG-A1-03-5 range of -25°C to 70°C. The substitute parts provide 5°C additional low-temperature capability.

Q: Are packaging and inventory considerations relevant to substitution?

A: All parts are supplied in bulk packaging. Current inventory levels are: SG-A1-03-5 (720 Pcs), D4GS-N4T (837 Pcs), and D4GS-N4T-5 (672 Pcs). Inventory status may influence sourcing decisions but does not affect functional compatibility.
