Omron G2R-2-ASI AC240 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron G2R-2-ASI AC240 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 5A at 240VAC coil voltage. This through-hole mounted relay is designed for industrial control applications requiring sealed flux protection and reliable switching performance across a wide operating temperature range. The part is currently active in production with full RoHS compliance. Substitute parts are identified when identical electrical and mechanical parameters are maintained across different packaging or certification variants within the same product series.

Substitute Part Grouping Explanation

Substitution eligibility for the G2R-2-ASI AC240 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to qualify as a direct substitute:

Coil voltage: 240VAC
Contact configuration: DPDT (2 Form C)
Contact current rating: 5A
Switching voltage maximum: 380VAC, 125VDC
Mounting type: Through Hole
Termination style: PC Pin
Coil current: 3.8 mA
Coil resistance: 30 kOhms
Must operate and release voltages: 192 VAC / 72 VAC
Operating temperature range: -40°C ~ 70°C
Contact material: Silver Alloy
Seal rating: Sealed - Flux Protection

Variations in packaging format (bulk versus tray) and RoHS certification revision level do not affect electrical or mechanical compatibility and are permitted within the substitution group.

Engineering Selection Recommendations

Both the G2R-2-ASI AC240 and G2R-2-AC240 are active production parts from Omron Electronics Inc-EMC Div with full compliance to current regulatory standards. The G2R-2-AC240 carries ROHS3 certification, representing the latest RoHS revision level, while the G2R-2-ASI AC240 maintains RoHS compliance. Both parts are classified as EAR99 for export control purposes and carry identical HTSUS tariff codes.

Selection between these parts should be based on packaging requirements and supply chain considerations. The G2R-2-AC240 in tray packaging is suitable for automated assembly and high-volume production environments. The G2R-2-ASI AC240 in bulk packaging is appropriate for manual assembly, repair, and lower-volume applications. Electrical performance and mechanical compatibility are identical across both variants.

Frequently Asked Questions (FAQ)

Q: Can G2R-2-AC240 be used as a direct replacement for G2R-2-ASI AC240?

A: Yes. Both parts maintain identical electrical specifications, contact ratings, coil parameters, and mechanical mounting characteristics. The only differences are packaging format and RoHS certification revision level, neither of which affects functional compatibility.

Q: What is the difference between bulk and tray packaging for these relays?

A: Bulk packaging is suitable for manual handling and lower-volume applications. Tray packaging is designed for automated pick-and-place assembly equipment and high-volume production environments. Electrical and mechanical specifications remain unchanged.

Q: Does the ROHS3 certification on G2R-2-AC240 provide additional benefits over RoHS compliance on G2R-2-ASI AC240?

A: ROHS3 represents the current revision of the RoHS directive with updated substance restrictions. Both certifications confirm compliance with hazardous substance limitations. Selection should be based on customer or end-market requirements for specific RoHS revision levels.

Q: Are the coil voltage and contact ratings identical between these parts?

A: Yes. Both parts feature 240VAC coil voltage, 5A contact rating, DPDT contact configuration, and identical switching voltage maximums of 380VAC and 125VDC.

Q: What is the operating temperature range for these relays?

A: Both parts operate reliably across -40°C to 70°C, with sealed flux protection maintaining performance in industrial environments.
