Omron G7L-2A-TUB-CB-IN AC24 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron G7L-2A-TUB-CB-IN AC24 is a general purpose relay with DPST-NO (2 Form A) contact configuration rated for 25A at 250VAC maximum switching voltage. The relay operates on a 24VAC coil with 71mA coil current and features chassis mount termination via quick connect 0.250" (6.3mm) terminals. This relay is actively produced, RoHS compliant, and maintains 1073 units in current inventory stock. Substitute parts are identified when identical electrical and mechanical parameters are maintained across different packaging or termination configurations within the same product series.

Substitute Part Grouping Explanation

Substitution within the G7L series is determined by equivalence across the following critical parameters: coil voltage (24VAC), contact configuration (DPST-NO), current rating (25A), switching voltage (250VAC maximum), coil current (71mA), mounting type (chassis mount), and termination style (quick connect 0.250"). The G7L-2A-T-CB AC24 qualifies as a parametric equivalent because all electrical characteristics, mechanical mounting, and termination specifications are identical to the main part. The only difference is packaging configuration: the main part is supplied in tube packaging (TUB) while the substitute is supplied in bulk (Bulk) packaging. Both parts share the same base product number G7L-2A and maintain identical performance specifications across all operating conditions.

Engineering Selection Recommendations

Both the G7L-2A-TUB-CB-IN AC24 and G7L-2A-T-CB AC24 are active production parts with RoHS compliance and identical electrical performance specifications. Selection between these parts is determined by packaging requirements and inventory availability rather than functional capability. The tube-packaged variant (TUB-CB-IN) is suitable for applications requiring individual unit handling or smaller quantity orders, while the bulk-packaged variant (T-CB) is appropriate for high-volume manufacturing environments or applications where component packaging consolidation is preferred. Both parts maintain equivalent performance across all specified operating parameters and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the G7L-2A-T-CB AC24 be used as a direct replacement for the G7L-2A-TUB-CB-IN AC24?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. The substitute part will function identically in any circuit or application designed for the main part.

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

A: Tube packaging (TUB) provides individual component containment suitable for smaller orders or manual assembly processes. Bulk packaging consolidates multiple units for high-volume manufacturing environments. Electrical and mechanical specifications remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both the G7L-2A-TUB-CB-IN AC24 and G7L-2A-T-CB AC24 are RoHS compliant and suitable for applications requiring environmental compliance certification.

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

A: Both parts require 24VAC coil voltage with a coil current of 71mA and coil resistance of 303 Ohms. The must-operate voltage is 18VAC and must-release voltage is 3.6VAC.

Q: What is the maximum switching voltage for these relays?

A: Both parts are rated for a maximum switching voltage of 250VAC with a contact current rating of 25A in DPST-NO (2 Form A) configuration.

Q: Are the termination styles identical between both parts?

A: Yes. Both parts use quick connect termination with 0.250" (6.3mm) terminals for chassis mount applications.

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

A: Both parts operate across a temperature range of -25°C to 60°C with identical performance specifications throughout this range.
