Omron G5LE-1A4-ASI DC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron G5LE-1A4-ASI DC12 is a general purpose relay with SPST-NO (1 Form A) contact configuration, rated for 10A at 12VDC coil voltage. This through-hole mounted relay is designed for standard switching applications requiring sealed, fully enclosed construction with Class B coil insulation. The part is active in production and RoHS compliant, making it suitable for modern electronic assemblies. Alternative part numbers within the G5LE series provide equivalent electrical and mechanical performance for applications requiring different packaging formats or inventory availability.

Substitute Part Grouping Explanation

Substitution within the G5LE-1A4 series is determined by electrical equivalence across all critical parameters: 12VDC coil voltage, SPST-NO contact configuration, 10A current rating, 250VAC/125VDC switching voltage, and identical coil characteristics (33.3 mA, 360 Ohms). All substitute parts maintain the same through-hole mounting, PC pin termination, sealed construction, and operating temperature range. Differences are limited to packaging format (tray versus individual packaging) and RoHS certification status, neither of which affects electrical or mechanical compatibility in the application circuit.

Engineering Selection Recommendations

All three part numbers are active products from Omron Electronics Inc-EMC Div and maintain full electrical and mechanical compatibility. Selection between G5LE-1A4-ASI DC12, G5LE-1A4 DC12, and G5LE-1A4-VD DC12 should be based on packaging requirements and compliance specifications for the end application.

G5LE-1A4-ASI DC12 is supplied in individual packaging and carries RoHS Compliant certification. G5LE-1A4 DC12 and G5LE-1A4-VD DC12 are supplied in tray packaging and carry ROHS3 Compliant certification with REACH Unaffected status. For applications requiring ROHS3 compliance documentation, either G5LE-1A4 DC12 or G5LE-1A4-VD DC12 is appropriate. For high-volume production requiring tray packaging, G5LE-1A4 DC12 offers the largest available inventory (20,851 pcs). For applications with individual part requirements, G5LE-1A4-ASI DC12 is the designated option.

Frequently Asked Questions (FAQ)

Q: Can G5LE-1A4 DC12 be used as a direct replacement for G5LE-1A4-ASI DC12?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 12VDC coil voltage, SPST-NO contact configuration, 10A rating, 250VAC/125VDC switching voltage, and identical coil characteristics. The primary difference is packaging format (tray versus individual) and RoHS certification status (ROHS3 versus RoHS Compliant). Circuit performance is unaffected by this substitution.

Q: What is the difference between G5LE-1A4-VD DC12 and G5LE-1A4 DC12?

A: Both parts are electrically and mechanically equivalent with identical electrical specifications, coil voltage, contact ratings, and operating characteristics. Both are supplied in tray packaging and carry ROHS3 Compliant certification with REACH Unaffected status. The part number suffix (-VD) indicates a specific packaging or distribution variant. Selection between these two should be based on inventory availability and supplier preference.

Q: Are all three parts suitable for the same PCB footprint?

A: Yes. All three parts share identical through-hole mounting specifications and PC pin termination. PCB footprints designed for any one of these part numbers will accommodate all three without modification.

Q: What compliance certifications apply to each part?

A: G5LE-1A4-ASI DC12 carries RoHS Compliant certification. G5LE-1A4 DC12 and G5LE-1A4-VD DC12 carry ROHS3 Compliant certification with REACH Unaffected status. All three parts are classified as EAR99 for export control purposes.

Q: Can these relays be used interchangeably in existing designs?

A: Yes. All three parts maintain identical electrical performance, coil resistance (360 Ohms), coil current (33.3 mA), operate time (10 ms), and release time (5 ms). No circuit redesign or validation is required when substituting between these part numbers.
