Omron G7L-2A-P-CB AC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron G7L-2A-P-CB AC12 is a general purpose relay with DPST-NO (2 Form A) contact configuration, rated for 20A at 250VAC maximum switching voltage. The relay operates on a 12VAC coil with 142mA coil current and features non-latching operation with 30ms operate and release times. This through-hole mounted relay is designed for industrial control applications requiring reliable switching performance across standard operating temperature ranges of -25°C to 60°C. The product maintains active status with RoHS compliance and is widely stocked for immediate availability.

Alternative models may be required due to packaging preferences, inventory constraints, or specific compliance certifications needed for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the G7L-2A-P-CB AC12 is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (12VAC)
• Contact configuration (DPST-NO, 2 Form A)
• Current rating (20A minimum)
• Maximum switching voltage (250VAC)
• Coil current draw (142mA)
• Non-latching operation
• Through-hole mounting with PC pin termination
• Operating temperature range (-25°C to 60°C)
• Contact material composition (Silver Tin Indium)

Parts meeting all these criteria are classified as parametric equivalents. Variations in packaging format, inventory status, or compliance certifications do not affect functional substitutability when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the G7L-2A-P-CB AC12 and G7L-2A-P-CB-AC12 are parametric equivalents with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance Requirements: The main part (G7L-2A-P-CB AC12) carries RoHS Compliant certification, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS compliance. The substitute part (G7L-2A-P-CB-AC12) is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging and Inventory: The main part is available in standard packaging with 802 units in stock. The substitute is supplied in bulk packaging with 727 units available. Packaging selection depends on procurement volume and handling requirements.

Product Status: Both parts maintain active product status, ensuring continued manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the G7L-2A-P-CB-AC12 be used as a direct replacement for the G7L-2A-P-CB AC12?

A: Yes, from an electrical and mechanical standpoint. Both parts are parametric equivalents with identical coil voltage (12VAC), contact configuration (DPST-NO), current rating (20A), and switching specifications. However, if your application requires RoHS compliance, the main part (G7L-2A-P-CB AC12) is the correct choice, as the substitute is RoHS non-compliant.

Q: What are the critical parameters that define substitutability for this relay?

A: Substitutability is determined by equivalence in coil voltage (12VAC), contact form (DPST-NO, 2 Form A), current rating (20A), maximum switching voltage (250VAC), coil current (142mA), non-latching operation, through-hole mounting with PC pin termination, operating temperature range (-25°C to 60°C), and contact material (Silver Tin Indium).

Q: Does packaging format affect functional performance?

A: No. The main part is supplied in standard packaging while the substitute is supplied in bulk packaging. Packaging format does not affect relay performance, switching characteristics, or electrical specifications. Selection should be based on procurement requirements and handling procedures.

Q: Are there any compliance differences between these parts?

A: Yes. The main part (G7L-2A-P-CB AC12) is RoHS Compliant. The substitute part (G7L-2A-P-CB-AC12) is RoHS non-compliant. Both parts carry EAR99 ECCN classification. If your application or customer specifications mandate RoHS compliance, use the main part.

Q: What is the coil resistance and how does it affect circuit design?

A: Both parts have a coil resistance of 75 Ohms. This specification is critical for calculating coil current draw and selecting appropriate drive circuitry. The specified coil current of 142mA at 12VAC confirms this resistance value and should be used for power supply and control circuit sizing.

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

A: Yes. Both parts use identical through-hole PC pin termination and have the same physical mounting configuration. No PCB layout modifications are required when substituting between these parts.
