Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HJ2-AC120V-6 is determined by the following critical parameters:

• Coil voltage: 120VAC (primary functional requirement)
• Contact form: DPDT (2 Form C) (electrical configuration requirement)
• Mounting type: Socketable (mechanical compatibility requirement)
• Termination style: Plug In (socket compatibility requirement)
• Contact rating: Minimum 7A (current handling capacity)
• Switching voltage: 250VAC, 125VDC - Max (voltage withstand capability)
• Coil type: Non Latching (operational characteristic)

The LY2-AC110/120 manufactured by Omron Automation and Safety meets all critical substitution criteria. This relay maintains identical coil voltage, contact form, mounting type, and termination style specifications. The substitute part exceeds the original contact rating (10A vs. 7A) and maintains equivalent switching voltage specifications, making it suitable for direct replacement in socketable relay applications.

Parameter Comparison

Engineering Selection Recommendations

The LY2-AC110/120 is the qualified substitute for the obsolete HJ2-AC120V-6. Selection is based on the following factors:

• Product status: The substitute part is active and currently available, addressing the obsolescence of the original component.
• Electrical compatibility: Identical coil voltage, contact form, switching voltage, and coil operation characteristics ensure functional equivalence in 120VAC switching applications.
• Mechanical compatibility: Socketable mounting type and plug-in termination style provide direct socket compatibility without mechanical modification.
• Performance margin: The substitute part's higher contact rating (10A vs. 7A) provides additional current handling capacity within the same physical form factor.
• Regulatory compliance: The substitute part carries RoHS Compliant certification, meeting current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the LY2-AC110/120 be used as a direct replacement for the HJ2-AC120V-6?

A: Yes. Both relays share identical coil voltage (120VAC), contact form (DPDT), mounting type (socketable), and termination style (plug-in). The substitute part will function in the same socket without modification.

Q: What is the difference in contact rating between these relays?

A: The HJ2-AC120V-6 is rated for 7A, while the LY2-AC110/120 is rated for 10A. The higher rating of the substitute part does not create compatibility issues; it indicates greater current handling capacity for the same switching application.

Q: Are there differences in operating temperature ranges?

A: Yes. The HJ2-AC120V-6 operates from -40°C to 70°C, while the LY2-AC110/120 operates from -25°C to 55°C. For applications requiring operation below -25°C or above 55°C, the original specification must be verified against system requirements.

Q: What is the coil current difference?

A: The HJ2-AC120V-6 draws 10.3 mA, while the LY2-AC110/120 draws 9.2 mA. This lower coil current in the substitute part may provide a slight reduction in power consumption and heat generation.

Q: Is the substitute part RoHS compliant?

A: Yes. The LY2-AC110/120 is RoHS Compliant. The original HJ2-AC120V-6 RoHS status was not specified in the provided data.

Q: What are the switching voltage specifications?

A: Both relays are rated for 250VAC and 125VDC maximum switching voltage, ensuring equivalent performance in AC and DC switching circuits within these voltage limits.
