Parameter Comparison

Engineering Selection Recommendations

LY1-AC220/240 (Direct Substitute - Omron): This part is classified as a direct substitute and is the primary recommendation for HC1-H-AC240V-F replacement. It maintains identical contact form, coil voltage, mounting type, and termination style. The LY1-AC220/240 provides higher contact rating (15A versus 10A), offering improved current handling capacity. The product is Active status with RoHS Compliance certification, ensuring long-term availability and environmental regulatory compliance. Coil current is slightly lower (4.6mA versus 5mA), and switching response times are marginally longer (25ms versus 20ms), which are acceptable variations for general purpose relay applications.

G2R-1-S AC240(S) (Similar Substitute - Omron): This part is classified as a similar substitute and provides an alternative option where the LY1-AC220/240 is unavailable. It maintains identical contact form, coil voltage, mounting type, and coil type. The G2R-1-S AC240(S) matches the 10A contact rating of the original part and offers superior switching voltage capability (440VAC maximum versus 250VAC). The product is Active status with ROHS3 Compliance and REACH Unaffected certifications. Notably, this part features lower coil current (3.2mA) and faster switching response times (15ms operate, 10ms release), providing performance advantages in applications requiring rapid switching. The operating temperature range extends to -40°C, offering broader environmental tolerance.

Both substitute parts are manufactured by Omron Automation and Safety, an established relay manufacturer with equivalent product reliability standards. Selection between LY1-AC220/240 and G2R-1-S AC240(S) should be based on specific application requirements regarding contact current capacity, switching speed, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the LY1-AC220/240 be used as a direct replacement for the HC1-H-AC240V-F?

A: Yes. The LY1-AC220/240 meets all core compatibility requirements: SPDT contact form, 240VAC coil voltage, socketable mounting, plug-in termination, and non-latching coil type. The higher 15A contact rating provides enhanced current handling without compromising compatibility.

Q: What is the difference between a "Direct" and "Similar" substitute?

A: Direct substitutes (LY1-AC220/240) maintain all critical electrical and mechanical parameters with only beneficial variations such as higher current ratings. Similar substitutes (G2R-1-S AC240(S)) maintain core compatibility but may have additional features or different performance characteristics, such as enhanced switching voltage capability or faster response times.

Q: Are there any termination compatibility concerns with the G2R-1-S AC240(S)?

A: The G2R-1-S AC240(S) offers both Plug In and Quick Connect - 0.187" (4.7mm) termination options. Applications requiring standard plug-in termination are compatible. Verify socket compatibility if the application uses a dedicated relay socket designed specifically for the HC1-H-AC240V-F.

Q: How do the operating temperature ranges compare?

A: The HC1-H-AC240V-F operates from -50°C to 70°C. The LY1-AC220/240 operates from -25°C to 55°C, and the G2R-1-S AC240(S) operates from -40°C to 70°C. For applications requiring operation below -25°C, the G2R-1-S AC240(S) is the appropriate selection.

Q: What is the significance of the coil current differences?

A: The HC1-H-AC240V-F requires 5mA coil current, while the LY1-AC220/240 requires 4.6mA and the G2R-1-S AC240(S) requires 3.2mA. Lower coil current in substitute parts reduces power consumption and heat generation in the control circuit, providing operational efficiency benefits without affecting relay function.

Q: Are both substitute parts RoHS compliant?

A: Yes. The LY1-AC220/240 is RoHS Compliant. The G2R-1-S AC240(S) is ROHS3 Compliant and REACH Unaffected, meeting current environmental regulatory requirements for electronic component manufacturing and distribution.
