HC2-HL-AC24V-F Equivalent & Substitute Parts

Part Overview

The HC2-HL-AC24V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 24VAC coil. This socketable relay is designed for applications requiring 7A contact rating at 250VAC maximum switching voltage, with integrated lighted indicator functionality. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-HL-AC24V-F is determined by strict alignment of the following critical parameters:

• Contact Form: Must be DPDT (2 Form C) to maintain identical switching capability
• Coil Voltage: Must be 24VAC to ensure direct compatibility with existing control circuits
• Mounting Type: Must be Socketable with Plug In termination to fit existing relay bases
• Coil Type: Must be Non Latching to preserve operational behavior
• Contact Rating (Current): Substitute must meet or exceed 7A minimum requirement
• Switching Voltage: Substitute must support 250VAC minimum switching capability
• Must Operate/Release Voltages: Must match 19.2 VAC and 7.2 VAC thresholds for circuit compatibility

The LY2N-AC24 from Omron Automation and Safety satisfies all mandatory substitution criteria, with enhanced contact rating (10A) and additional switching voltage capability (125VDC).

Engineering Selection Recommendations

The LY2N-AC24 is the qualified substitute for the obsolete HC2-HL-AC24V-F. Selection is based on the following engineering factors:

Product Status: The HC2-HL-AC24V-F is obsolete, while the LY2N-AC24 maintains active product status with ongoing manufacturer support and availability.

Compliance & Certifications: The LY2N-AC24 is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards. Both parts carry EAR99 ECCN classification.

Functional Equivalence: The LY2N-AC24 maintains identical coil voltage (24VAC), contact form (DPDT), and switching thresholds (19.2 VAC operate, 7.2 VAC release), ensuring direct functional replacement in existing circuits.

Performance Enhancement: The LY2N-AC24 provides increased contact rating (10A versus 7A) and extended switching voltage capability (125VDC support), offering improved margin for applications at or near the original 7A specification.

Thermal Consideration: The HC2-HL-AC24V-F operates across -50°C to 60°C, while the LY2N-AC24 operates across -25°C to 55°C. Applications requiring operation below -25°C require thermal performance verification.

Frequently Asked Questions (FAQ)

Q: Can the LY2N-AC24 directly replace the HC2-HL-AC24V-F without circuit modification?

A: Yes. Both relays share identical coil voltage (24VAC), contact form (DPDT), and switching thresholds (19.2 VAC operate, 7.2 VAC release). The socketable mounting and plug-in termination are identical, enabling direct socket substitution.

Q: What is the significance of the higher 10A contact rating on the LY2N-AC24?

A: The LY2N-AC24 contact rating of 10A exceeds the HC2-HL-AC24V-F requirement of 7A. This provides operational margin and is suitable for applications at or below the original 7A specification. No circuit derating is required.

Q: Are there temperature range limitations when substituting?

A: The HC2-HL-AC24V-F operates from -50°C to 60°C, while the LY2N-AC24 operates from -25°C to 55°C. Applications requiring operation below -25°C must verify the LY2N-AC24 is suitable for the specific thermal environment.

Q: What is the difference in switching voltage capability?

A: The HC2-HL-AC24V-F supports 250VAC maximum. The LY2N-AC24 supports both 250VAC and 125VDC, providing additional flexibility for DC switching applications. Both meet the original 250VAC requirement.

Q: How do the timing specifications compare?

A: The HC2-HL-AC24V-F operates and releases in 20 ms. The LY2N-AC24 operates and releases in 25 ms. This 5 ms difference is within typical relay tolerance and does not affect standard control applications. Applications with critical timing requirements must verify compatibility.

Q: Is the LY2N-AC24 compatible with existing relay bases designed for the HC2-HL-AC24V-F?

A: Yes. Both relays are socketable with plug-in termination, designed for standard relay base compatibility. Physical and electrical interface compatibility is maintained.

Q: What compliance standards apply to the LY2N-AC24?

A: The LY2N-AC24 is RoHS Compliant and REACH Unaffected, meeting current environmental regulations. Both parts carry EAR99 ECCN classification for export control purposes.
