HC2-HP-AC100V-F Equivalent & Substitute Parts

Part Overview

The HC2-HP-AC100V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 100VAC coil. This through-hole mounted relay is rated for 7A at 250VAC maximum switching voltage and operates across a temperature range of -50°C to 70°C. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where this relay is specified in legacy equipment.

Key Parameters

Substitute Part Grouping Explanation

The LY2-0-AC100/110 from Omron Automation and Safety qualifies as a substitute based on the following critical parameters:

Functional Equivalence Criteria:

• Contact Form: Both parts feature DPDT (2 Form C) configuration, enabling identical switching logic
• Coil Type: Both are non-latching relays with AC coil operation
• Termination Style: Both use PC Pin termination for through-hole mounting
• Relay Type: Both are general purpose relays

Electrical Compatibility Parameters:

• Coil Voltage: HC2-HP-AC100V-F operates at 100VAC; LY2-0-AC100/110 operates at 110VAC. This 10% variance falls within standard industrial AC supply tolerance and is acceptable for substitution
• Contact Rating: LY2-0-AC100/110 is rated for 10A, exceeding the HC2-HP-AC100V-F requirement of 7A, providing margin for reliability
• Switching Voltage: Both support 250VAC maximum, ensuring equivalent load-switching capability
• Must Operate Voltage: HC2-HP-AC100V-F requires 80VAC minimum; LY2-0-AC100/110 requires 88VAC minimum. Both operate within standard AC supply ranges
• Must Release Voltage: HC2-HP-AC100V-F releases at 30VAC; LY2-0-AC100/110 releases at 33VAC. Both values are within acceptable industrial margins

Mechanical Compatibility:

• Mounting Type: Both are through-hole mounted, compatible with existing PCB layouts
• Contact Material: Both use silver alloy contacts, ensuring similar contact resistance and switching characteristics

Engineering Selection Recommendations

The LY2-0-AC100/110 is suitable as a substitute for the obsolete HC2-HP-AC100V-F based on the following factors:

Product Status Advantage: The LY2-0-AC100/110 is an active product with current manufacturing and supply chain availability, eliminating obsolescence risk associated with the HC2-HP-AC100V-F.

Compliance and Certification: The LY2-0-AC100/110 carries ROHS3 compliance and REACH unaffected status, meeting modern environmental and regulatory requirements. Both parts share the same ECCN classification (EAR99).

Electrical Performance: The LY2-0-AC100/110 delivers superior current rating (10A versus 7A) and lower coil current consumption (11 mA versus 13.2 mA), providing operational margin and reduced power draw. The 110VAC coil voltage aligns with standard industrial AC supply tolerances relative to the 100VAC specification.

Mechanical Compatibility: Identical through-hole PC pin termination ensures direct PCB layout compatibility without redesign requirements.

Operating Envelope Consideration: The LY2-0-AC100/110 operates within -25°C to 55°C, which is narrower than the HC2-HP-AC100V-F range of -50°C to 70°C. Applications requiring operation below -25°C or above 55°C require thermal environment verification.

Frequently Asked Questions (FAQ)

Q: Can the LY2-0-AC100/110 directly replace the HC2-HP-AC100V-F without PCB modifications?

A: Yes. Both relays use identical through-hole PC pin termination and DPDT contact configuration. No PCB layout changes are required for mechanical and electrical connection.

Q: Is the 110VAC coil voltage compatible with 100VAC supply systems?

A: Yes. The 10% voltage difference falls within standard industrial AC supply tolerance. The LY2-0-AC100/110 must operate voltage of 88VAC and the HC2-HP-AC100V-F requirement of 80VAC both accommodate typical AC supply variations in industrial environments.

Q: What is the impact of the higher 10A current rating on the LY2-0-AC100/110?

A: The higher current rating provides additional safety margin for the application. If the original circuit requires only 7A, the 10A-rated substitute operates with reduced stress on contacts, potentially extending service life. No circuit modifications are necessary.

Q: Does the LY2-0-AC100/110 support the same switching voltage as the original part?

A: Yes. Both parts support 250VAC maximum switching voltage. The LY2-0-AC100/110 additionally supports 125VDC switching, providing expanded load compatibility.

Q: Are there temperature range limitations when substituting?

A: The LY2-0-AC100/110 operates from -25°C to 55°C, compared to the HC2-HP-AC100V-F range of -50°C to 70°C. Applications requiring operation below -25°C or above 55°C must verify that the narrower operating range is acceptable for the specific thermal environment.

Q: What is the difference in switching speed between these relays?

A: The LY2-0-AC100/110 has operate and release times of 25 ms, compared to 20 ms for the HC2-HP-AC100V-F. This 5 ms difference is negligible for general purpose relay applications and does not affect standard industrial control logic.

Q: Is the LY2-0-AC100/110 RoHS compliant?

A: Yes. The LY2-0-AC100/110 is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The HC2-HP-AC100V-F compliance status is not specified in available documentation.
