HC2-H-AC12V-F Equivalent & Substitute Parts

Part Overview

The HC2-H-AC12V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 12VAC coil and 7A contact rating. This socketable relay is designed for standard switching applications requiring 250VAC maximum switching voltage. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-H-AC12V-F is determined by the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 12VAC
• Contact Form: DPDT (2 Form C)
• Mounting Type: Socketable
• Termination Style: Plug In
• Coil Type: Non Latching

Compatible Operating Parameters:

• Must Operate Voltage: 9.6 VAC (minimum)
• Must Release Voltage: 3.6 VAC (maximum)
• Contact Rating (Current): Equal to or greater than 7A
• Switching Voltage: Equal to or greater than 250VAC

The LY2-AC12 from Omron Automation and Safety meets all mandatory matching parameters and exceeds the contact current rating (10A vs. 7A), making it a direct functional substitute for the obsolete HC2-H-AC12V-F.

Engineering Selection Recommendations

The LY2-AC12 is the primary substitute for the HC2-H-AC12V-F. Selection is based on the following engineering factors:

Product Status: The HC2-H-AC12V-F is obsolete, while the LY2-AC12 is active and currently in production, ensuring long-term availability and supply chain continuity.

Compliance: The LY2-AC12 is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements. Both parts carry EAR99 ECCN classification.

Functional Compatibility: The LY2-AC12 maintains identical coil voltage, contact form, mounting configuration, and termination style. The higher contact current rating (10A vs. 7A) provides additional margin for applications originally designed for the HC2-H-AC12V-F.

Operating Characteristics: Timing parameters differ slightly (25ms vs. 20ms for both operate and release times). The LY2-AC12 operates within a narrower temperature range (-25°C ~ 55°C vs. -50°C ~ 70°C), which may require evaluation for applications requiring extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the LY2-AC12 directly replace the HC2-H-AC12V-F in existing applications?

A: Yes. Both relays share identical coil voltage (12VAC), contact form (DPDT), mounting type (socketable), and termination style (plug in). The LY2-AC12 provides higher contact current capacity (10A vs. 7A), making it suitable for the same or higher current applications.

Q: What are the differences in operating characteristics?

A: The LY2-AC12 has slightly longer operate and release times (25ms vs. 20ms). Operating temperature range differs: the HC2-H-AC12V-F operates from -50°C to 70°C, while the LY2-AC12 operates from -25°C to 55°C. Applications requiring extreme temperature operation should evaluate this difference.

Q: Are there compliance differences between these parts?

A: The LY2-AC12 is RoHS Compliant and REACH Unaffected, meeting current environmental regulations. The HC2-H-AC12V-F compliance status is not specified. Both carry EAR99 ECCN classification.

Q: What is the coil current difference, and does it matter?

A: The LY2-AC12 draws 91mA compared to 100mA for the HC2-H-AC12V-F. This 9mA reduction may provide minor power savings in applications with multiple relays but does not affect functional compatibility.

Q: Are the contact materials compatible?

A: Both use silver alloy contacts. The HC2-H-AC12V-F specifies cadmium-free silver alloy, while the LY2-AC12 specifies silver alloy. Both are suitable for general purpose switching applications.

Q: What packaging is available?

A: The HC2-H-AC12V-F is available in standard packaging. The LY2-AC12 is supplied in bulk packaging, which may affect procurement and handling procedures.
