Substitute Part Grouping Explanation

Substitution eligibility for the G2R-1-E-ASI DC18 is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (18VDC)
• Contact configuration (SPDT / 1 Form C)
• Current rating (16A)
• Switching voltage capability (380VAC, 125VDC maximum)
• Coil current draw (29.4 mA)
• Mounting technology (Through Hole)
• Termination method (PC Pin)
• Temporal characteristics (15 ms operate, 5 ms release)
• Environmental sealing (Sealed - Flux Protection)
• Temperature operating range (-40°C ~ 70°C)

The identified substitute part G2R-1-E DC18 maintains identical electrical and mechanical specifications. The difference between the main part and substitute is limited to packaging designation (tray versus standard packaging) and inventory source, with no impact on functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the G2R-1-E-ASI DC18 and G2R-1-E DC18 are active production parts manufactured by Omron Electronics Inc-EMC Div with full RoHS compliance. Selection between these parts should be based on:

• Packaging requirements: The G2R-1-E DC18 is supplied in tray packaging, while the G2R-1-E-ASI DC18 uses standard packaging.
• Inventory availability: The G2R-1-E DC18 has higher stock levels (1215 units) compared to the G2R-1-E-ASI DC18 (892 units).
• Supply chain lead times and procurement policies specific to your organization.

Both parts are functionally identical and will perform equivalently in any circuit designed for the G2R-1-E-ASI DC18 specification.

Frequently Asked Questions (FAQ)

Q: Can I use G2R-1-E DC18 as a direct replacement for G2R-1-E-ASI DC18?

A: Yes. Both parts are electrically and mechanically identical. All critical parameters including coil voltage, contact rating, switching characteristics, and operating temperature range are identical. The only difference is packaging format.

Q: What determines if a relay can substitute for the G2R-1-E-ASI DC18?

A: A substitute relay must match all of the following: 18VDC coil voltage, SPDT contact configuration, 16A current rating, 380VAC/125VDC switching voltage capability, 29.4 mA coil current, through-hole mounting, PC pin termination, sealed flux protection, 15 ms operate time, 5 ms release time, and -40°C to 70°C operating temperature range.

Q: Does packaging affect circuit performance?

A: No. Tray packaging versus standard packaging does not affect electrical performance or functional characteristics. The difference is purely in how the parts are supplied and handled during procurement and storage.

Q: Are both parts RoHS compliant?

A: Yes. Both G2R-1-E-ASI DC18 and G2R-1-E DC18 are RoHS compliant and suitable for applications requiring environmental compliance.

Q: What is the coil resistance specification?

A: Both parts have a coil resistance of 612 Ohms at 18VDC, which determines the coil current draw of 29.4 mA.
