HC2-H-AC6V-F Equivalent & Substitute Parts

Part Overview

The HC2-H-AC6V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 6VAC coil. This socketable relay is designed for applications requiring 7A contact rating at switching voltages up to 250VAC. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-H-AC6V-F is determined by the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 6VAC
• Contact Form: DPDT (2 Form C)
• Coil Type: Non Latching
• Mounting Type: Socketable
• Termination Style: Plug In
• Must Operate Voltage: 4.8 VAC
• Must Release Voltage: 1.8 VAC
• Operate Time: 20 ms
• Release Time: 20 ms

Allowable Variation Parameters:

• Contact Rating (Current): Substitute must meet or exceed 7A
• Switching Voltage: Substitute must support 250VAC minimum
• Operating Temperature Range: Substitute must cover or exceed -50°C ~ 70°C
• Coil Current: Minor variations acceptable within relay design specifications

The MY2 AC6 (S) from Omron Automation and Safety meets all mandatory matching parameters and satisfies allowable variation criteria, qualifying it as a direct substitute.

Engineering Selection Recommendations

The MY2 AC6 (S) qualifies as a direct substitute for the obsolete HC2-H-AC6V-F based on functional equivalence across all critical parameters. The following factors support this selection:

Product Status: The MY2 AC6 (S) is active and in production, ensuring availability for replacement and future procurement.

Compliance: Both relays are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications, supporting regulatory and trade compliance requirements.

Electrical Compatibility: Coil voltage, contact form, switching voltage, and timing specifications are identical. Operating voltage thresholds (must operate and must release) match precisely.

Mechanical Compatibility: Both relays feature socketable mounting with plug-in termination, enabling direct socket replacement without circuit board modifications.

Contact Rating Consideration: The MY2 AC6 (S) is rated for 5A continuous contact current, compared to the HC2-H-AC6V-F at 7A. Applications operating at or below 5A continuous current are fully compatible. Applications requiring sustained current above 5A require circuit redesign or alternative component selection.

Temperature Performance: The MY2 AC6 (S) extends the lower operating temperature limit to -55°C, providing enhanced performance in cold environments.

Frequently Asked Questions (FAQ)

Q: Can the MY2 AC6 (S) directly replace the HC2-H-AC6V-F in existing circuits?

A: Yes, for applications operating at contact currents of 5A or below. Both relays share identical coil voltage, contact configuration, switching voltage, timing, and mounting specifications. Direct socket substitution is possible without circuit modifications.

Q: What is the primary limitation of the MY2 AC6 (S) as a substitute?

A: The MY2 AC6 (S) has a maximum continuous contact rating of 5A, whereas the HC2-H-AC6V-F is rated for 7A. Applications requiring sustained currents between 5A and 7A cannot use this substitute without circuit redesign.

Q: Are there packaging differences between these relays?

A: The HC2-H-AC6V-F is specified with standard packaging, while the MY2 AC6 (S) is supplied in bulk packaging. Both are socketable relays with identical pin configurations and mounting footprints.

Q: Do both relays meet RoHS requirements?

A: Yes. The MY2 AC6 (S) is explicitly RoHS compliant. The HC2-H-AC6V-F uses cadmium-free silver alloy contacts, meeting RoHS material restrictions.

Q: What is the coil current difference, and does it affect circuit design?

A: The HC2-H-AC6V-F draws 200 mA, while the MY2 AC6 (S) draws 183 mA. This 17 mA reduction may allow use of lower-rated coil drive circuits in the substitute, but existing circuits designed for 200 mA operation remain compatible.

Q: Can the MY2 AC6 (S) operate at lower temperatures than the HC2-H-AC6V-F?

A: Yes. The MY2 AC6 (S) operates down to -55°C, compared to -50°C for the HC2-H-AC6V-F, providing a 5°C improvement in cold temperature performance.

Q: Are the switching voltage specifications equivalent?

A: The HC2-H-AC6V-F switches up to 250VAC. The MY2 AC6 (S) switches up to 250VAC and additionally supports 125VDC switching, making it suitable for a broader range of load types.
