HC2-HP-DC110V-F Equivalent & Substitute Parts

Part Overview

The HC2-HP-DC110V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 110VDC coil. This through-hole mounted relay is rated for 7A continuous current and 250VAC maximum switching voltage. The product is currently obsolete, making equivalent substitutes necessary for new designs, repairs, and system upgrades where this relay is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-HP-DC110V-F is determined by strict alignment of the following electrical and mechanical parameters:

• Coil Voltage: Must be 110VDC to ensure direct compatibility with existing power supply circuits
• Contact Form: Must be DPDT (2 Form C) to maintain circuit switching functionality
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Termination Style: Must be PC Pin for direct board connection
• Coil Current: Must be 10 mA to match control circuit requirements
• Must Operate and Release Voltages: Must be 88 VDC and 11 VDC respectively to ensure reliable operation within the specified voltage window
• Contact Rating (Current): Substitute must meet or exceed 7A minimum requirement
• Switching Voltage: Substitute must support 250VAC maximum or higher

The LY2-0-DC100/110 from Omron Automation and Safety meets all mandatory substitution criteria and is classified as an active product, providing long-term availability.

Engineering Selection Recommendations

The LY2-0-DC100/110 is the qualified substitute for the HC2-HP-DC110V-F based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters align precisely, including coil voltage, contact form, coil current, and voltage thresholds. The substitute's 10A contact rating exceeds the original 7A requirement, providing additional margin.

Mechanical Compatibility: Both relays share identical mounting type (Through Hole) and termination style (PC Pin), ensuring direct board-level replacement without layout modifications.

Product Status: The LY2-0-DC100/110 is an active product with confirmed inventory availability (1009 pcs), eliminating supply chain risk associated with the obsolete HC2-HP-DC110V-F.

Compliance: The LY2-0-DC100/110 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and manufacturing.

Operating Temperature Consideration: The substitute operates within -25°C to 55°C, which is narrower than the original -50°C to 70°C range. Verify this range is acceptable for your specific application environment.

Frequently Asked Questions (FAQ)

Q: Can the LY2-0-DC100/110 be used as a direct replacement for the HC2-HP-DC110V-F?

A: Yes. Both relays have identical coil voltage (110VDC), contact form (DPDT), mounting type (Through Hole), and termination style (PC Pin). The substitute's higher current rating (10A vs 7A) and additional switching voltage capability (125VDC) provide enhanced performance margins.

Q: What is the difference in operating temperature range between these relays?

A: The HC2-HP-DC110V-F operates from -50°C to 70°C, while the LY2-0-DC100/110 operates from -25°C to 55°C. If your application requires operation below -25°C or above 55°C, verify the substitute's temperature range is acceptable before implementation.

Q: Are there differences in switching speed between these relays?

A: The HC2-HP-DC110V-F has operate and release times of 20 ms each. The LY2-0-DC100/110 has operate and release times of 25 ms each. This 5 ms difference is typically negligible for general purpose relay applications but should be verified if timing-critical circuits are involved.

Q: What is the packaging difference between these parts?

A: The HC2-HP-DC110V-F is supplied in standard packaging, while the LY2-0-DC100/110 is supplied in bulk packaging. Both are through-hole mounted components suitable for PCB assembly.

Q: Are both relays RoHS compliant?

A: The HC2-HP-DC110V-F does not specify RoHS status. The LY2-0-DC100/110 is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for new designs.

Q: What is the coil resistance difference?

A: The HC2-HP-DC110V-F has 10 kOhms coil resistance, while the LY2-0-DC100/110 has 11 kOhms. This 1 kOhm difference is functionally equivalent and does not affect circuit operation with a 10 mA coil current specification.
