Omron G2R-1-ASI-DC24 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron G2R-1-ASI-DC24 is a general purpose relay with SPDT (1 Form C) contact configuration, rated for 10A at 24VDC coil voltage. This through-hole mounted relay is designed for applications requiring reliable switching in industrial control circuits. The part is currently active in production with 1112 pieces in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, allowing for component interchangeability in circuit designs while accommodating packaging, compliance, or inventory considerations.

Substitute Part Grouping Explanation

Substitution of the G2R-1-ASI-DC24 is determined by strict equivalence across the following critical parameters:

Coil voltage: 24VDC
Contact configuration: SPDT (1 Form C)
Current rating: 10A
Switching voltage capability: 380VAC, 125VDC maximum
Mounting type: Through hole
Coil current draw: 21.8 mA
Coil resistance: 1.1 kOhms
Voltage thresholds: Must operate at 16.8 VDC minimum, must release at 3.6 VDC maximum
Timing characteristics: 15 ms operate time, 5 ms release time
Temperature range: -40°C to 70°C

Engineering Selection Recommendations

Both the G2R-1-ASI-DC24 and G2R-1-DC24 are active production parts from Omron Electronics Inc-EMC Div with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The G2R-1-DC24 is ROHS3 compliant, while the G2R-1-ASI-DC24 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the G2R-1-DC24.

REACH Compliance: The G2R-1-DC24 carries REACH Unaffected status, providing additional regulatory clarity for European market applications.

Packaging Format: The G2R-1-DC24 is supplied in tray packaging, while the G2R-1-ASI-DC24 packaging format is not specified. Packaging selection depends on assembly process requirements and handling procedures.

Inventory Availability: The G2R-1-DC24 has higher stock availability (1900 pieces) compared to the G2R-1-ASI-DC24 (1112 pieces), which may influence procurement timelines.

Both parts are electrically and mechanically interchangeable for circuit applications requiring 24VDC SPDT relays with 10A contact rating.

Frequently Asked Questions (FAQ)

Q: Can the G2R-1-DC24 be used as a direct replacement for the G2R-1-ASI-DC24?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, contact configuration, coil voltage, current ratings, timing specifications, and operating temperature range. They are mechanically compatible for through-hole mounting with PC pin termination.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (tray for G2R-1-DC24 versus unspecified for G2R-1-ASI-DC24), RoHS compliance status (ROHS3 compliant versus non-compliant), and REACH regulatory status. Electrical and mechanical performance are identical.

Q: Which part should be selected for new designs?

A: For applications requiring RoHS compliance, the G2R-1-DC24 is the appropriate selection. For applications without RoHS requirements, either part meets the electrical specifications. Verify packaging requirements for your assembly process.

Q: Are there any timing or performance differences between these relays?

A: No. Both parts have identical operate time (15 ms), release time (5 ms), must-operate voltage (16.8 VDC), and must-release voltage (3.6 VDC) specifications.

Q: What is the coil current requirement for these relays?

A: Both relays draw 21.8 mA at 24VDC with a coil resistance of 1.1 kOhms. Circuit design must account for this current draw in the control signal source.

Q: Can these relays switch AC loads?

A: Yes. Both relays are rated for switching up to 380VAC at maximum voltage. The 10A contact rating applies to the load current capacity.
