SG-A1-02-5 Equivalent & Substitute Parts

Part Overview

The SG-A1-02-5 is a non-locking interlock DPST switch manufactured by Panasonic Industrial Automation Sales. This panel disconnect switch operates at 125VAC and 30VDC with a 2.5A current rating and features a 5-meter cable lead termination. The product is active and RoHS compliant with IP67 ingress protection rating.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when system design requires alternative sourcing options while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SG-A1-02-5 is determined by the following critical parameters:

Circuit configuration must remain DPST-NC to maintain electrical functionality. Both substitute parts (D4GS-N2T and D4GS-N2T-5) meet this requirement.

Actuator type and termination style must be Panel Disconnect with Cable Leads. Both substitutes match these specifications.

Ingress protection rating must be IP67 or equivalent. Both substitutes provide IP67 protection.

Current and voltage ratings are the primary limiting factors. The SG-A1-02-5 operates at 2.5A (AC/DC) and 125VAC/30VDC. The D4GS-N2T and D4GS-N2T-5 operate at 750mA (AC) and 240VAC. These reduced ratings indicate the substitutes are suitable only for applications requiring lower current and voltage specifications than the main part's maximum ratings.

Cable length differentiation: D4GS-N2T provides 1-meter cable length, while D4GS-N2T-5 provides 5-meter cable length matching the main part.

Parameter Comparison

Engineering Selection Recommendations

The D4GS-N2T-5 is the primary substitute candidate for the SG-A1-02-5 due to matching cable length (5m) and identical circuit configuration (DPST-NC). Both parts maintain IP67 ingress protection and share CE, cULus, and TUV certifications. The D4GS-N2T-5 extends the operating temperature range to -30°C and includes additional CCC approval.

The D4GS-N2T serves as a secondary substitute option when 1-meter cable length is acceptable for the application. This part shares all core electrical and mechanical characteristics with D4GS-N2T-5 except cable length.

Selection between these substitutes must account for current and voltage derating. Applications requiring the full 2.5A capacity or dual voltage operation (AC/DC) at 30VDC cannot use the Omron substitutes, which are limited to 750mA AC operation at 240VAC maximum.

Frequently Asked Questions (FAQ)

Q: Can D4GS-N2T or D4GS-N2T-5 directly replace SG-A1-02-5 in all applications?

A: No. The Omron substitutes operate at reduced current (750mA versus 2.5A) and different voltage specifications (240VAC versus 125VAC/30VDC). Substitution is valid only for applications operating within the Omron parts' electrical ratings.

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

A: Cable length is the only difference. D4GS-N2T provides 1-meter cable leads, while D4GS-N2T-5 provides 5-meter cable leads. All other electrical and mechanical parameters are identical.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both D4GS-N2T and D4GS-N2T-5 are ROHS3 compliant. The main part SG-A1-02-5 is RoHS compliant.

Q: Do the substitute parts support DC operation?

A: No. The D4GS-N2T and D4GS-N2T-5 are rated for AC operation only (750mA AC at 240VAC). The SG-A1-02-5 supports both AC and DC operation (2.5A AC/DC at 125VAC and 30VDC).

Q: Which certifications do all three parts share?

A: CE, cULus, and TUV certifications are common to SG-A1-02-5, D4GS-N2T, and D4GS-N2T-5. The Omron substitutes include additional CCC approval.
