HC2-H-DC12V-F Equivalent & Substitute Parts

Part Overview

The HC2-H-DC12V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 12VDC coil and 7A contact rating. This socketable relay is designed for standard switching applications requiring reliable electromagnetic actuation. The product is currently obsolete, making equivalent and substitute parts necessary for system maintenance, repair, and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-H-DC12V-F is determined by strict alignment of the following critical parameters:

Essential Matching Parameters:

• Coil voltage: 12VDC (all substitutes must operate at this voltage)
• Contact form: DPDT (2 Form C) configuration (electrical switching topology requirement)
• Mounting type: Socketable (physical form factor and base compatibility)
• Termination style: Plug In (connector interface requirement)
• Coil current: 75 mA (drive circuit compatibility)
• Coil resistance: 160 Ohms (electrical load matching)
• Must operate voltage: 9.6 VDC (minimum activation threshold)
• Must release voltage: 1.2 VDC (deactivation threshold)
• Coil type: Non Latching (functional behavior requirement)

Allowable Variation Parameters:

• Contact rating (current): Substitutes with equal or higher current rating are acceptable (7A minimum)
• Switching voltage: Substitutes must support minimum 250VAC
• Operating temperature range: Substitutes must cover the application temperature envelope
• Contact material: Variations permitted if electrical performance is maintained
• Operate/Release time: Variations permitted within application timing requirements

The three substitute parts listed below meet all essential matching parameters while maintaining functional equivalence for the HC2-H-DC12V-F application.

Parameter Comparison

Engineering Selection Recommendations

MY2 DC12 (S) - Omron Automation and Safety

This substitute provides direct functional equivalence with identical coil voltage, contact form, mounting type, and coil parameters. The contact rating of 5A is lower than the original 7A specification; this substitute is suitable for applications where the load current does not exceed 5A. The part is active in production with RoHS and REACH compliance, ensuring long-term availability and regulatory alignment. Operating temperature range extends to -55°C, providing superior low-temperature performance compared to the original specification.

KHAU-11D12-12 - TE Connectivity Potter & Brumfield Relays

This substitute meets all essential electrical parameters with identical coil voltage, contact form, and mounting configuration. The contact rating of 5A requires load current verification. The must operate voltage of 9VDC is lower than the original 9.6VDC specification, providing improved activation margin. Operate and release times are faster (13ms and 6ms respectively) compared to the original 20ms specification. The part is RoHS non-compliant and REACH affected; regulatory compliance must be evaluated for the target application. Operating temperature range of -45°C ~ 70°C covers the original specification envelope.

LY2-DC12 - Omron Automation and Safety

This substitute provides the highest contact rating at 10A, exceeding the original 7A specification and offering increased current capacity for higher-load applications. All essential electrical parameters match the original specification. The part is active in production with ROHS3 and REACH compliance. Operating temperature range of -25°C ~ 55°C is narrower than the original specification; this substitute is not suitable for applications requiring operation below -25°C. Operate and release times are slightly longer at 25ms compared to the original 20ms specification.

Frequently Asked Questions (FAQ)

Q: Can MY2 DC12 (S) replace HC2-H-DC12V-F in all applications?

A: MY2 DC12 (S) is functionally equivalent for applications where the load current does not exceed 5A. If the original application requires the full 7A contact rating, this substitute is not suitable. Verify the actual load current in your circuit before selection.

Q: What is the difference between the three substitute options?

A: The three substitutes differ primarily in contact rating and operating temperature range. MY2 DC12 (S) and KHAU-11D12-12 both provide 5A contact rating. LY2-DC12 provides 10A contact rating but has a narrower operating temperature range (-25°C ~ 55°C). Select based on your application's current requirements and temperature envelope.

Q: Is KHAU-11D12-12 suitable for new designs?

A: KHAU-11D12-12 is RoHS non-compliant and REACH affected. For new designs subject to RoHS or REACH regulations, this part is not recommended. MY2 DC12 (S) and LY2-DC12 are both RoHS compliant and REACH unaffected, making them preferable for regulated applications.

Q: Can I use LY2-DC12 in applications requiring operation below -25°C?

A: No. LY2-DC12 has an operating temperature range of -25°C ~ 55°C. The original HC2-H-DC12V-F specification extends to -50°C. For low-temperature applications, MY2 DC12 (S) (-55°C ~ 70°C) or KHAU-11D12-12 (-45°C ~ 70°C) are suitable alternatives.

Q: Are all substitutes socketable with plug-in termination?

A: Yes. All three substitute parts are socketable relays with plug-in termination, matching the original HC2-H-DC12V-F form factor and base compatibility.

Q: What is the coil current requirement for all these relays?

A: All four relays (original and three substitutes) require 75mA coil current with 160 Ohms coil resistance. Drive circuit compatibility is maintained across all options.

Q: Do the substitutes have the same switching voltage capability?

A: The original HC2-H-DC12V-F supports 250VAC maximum. MY2 DC12 (S) and LY2-DC12 support 250VAC and 125VDC. KHAU-11D12-12 supports 240VAC maximum. All meet or exceed the original 250VAC specification for AC switching applications.
