HC3-HP-AC240V-F Equivalent & Substitute Parts

Part Overview

The HC3-HP-AC240V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with a 240VAC coil. This through-hole mounted relay is designed for applications requiring multiple independent switching circuits with a 7A contact rating at 250VAC maximum switching voltage. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC3-HP-AC240V-F is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 240VAC
• Contact Form: 3PDT (3 Form C)
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Type: Non Latching

Allowable Parameter Variations:

• Contact Rating (Current): Substitute must equal or exceed 7A
• Switching Voltage (Max): Substitute must equal or exceed 250VAC
• Coil Current: Substitute may vary within design tolerance
• Operate/Release Time: Substitute may vary within acceptable switching performance windows
• Operating Temperature Range: Substitute may have narrower range if application requirements are met
• Contact Material: Silver Alloy compositions acceptable

The LY3-0-AC240 from Omron Automation and Safety meets all mandatory matching criteria and exceeds the contact current rating (10A vs. 7A), making it a valid substitute for the obsolete HC3-HP-AC240V-F.

Parameter Comparison

Engineering Selection Recommendations

The LY3-0-AC240 is a direct substitute for the obsolete HC3-HP-AC240V-F based on functional equivalence across all critical parameters. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Higher contact current rating (10A vs. 7A) provides additional margin for existing 7A applications
• Dual switching voltage capability (250VAC and 125VDC) extends application flexibility
• RoHS compliance certification meets modern regulatory requirements
• Identical coil voltage, contact form, and termination style ensure mechanical and electrical compatibility

The LY3-0-AC240 operates within the same voltage thresholds (192VAC must-operate, 72VAC must-release) and maintains equivalent non-latching coil behavior. The 5ms increase in operate and release times (25ms vs. 20ms) remains within acceptable switching performance parameters for general purpose relay applications.

Frequently Asked Questions (FAQ)

Q: Can the LY3-0-AC240 be used as a direct replacement for the HC3-HP-AC240V-F?

A: Yes. Both relays share identical coil voltage (240VAC), contact form (3PDT), mounting type (through hole), and termination style (PC pin). The substitute meets or exceeds all critical electrical parameters required for functional equivalence.

Q: What is the significance of the higher 10A contact rating on the LY3-0-AC240?

A: The LY3-0-AC240 is rated for 10A maximum contact current, compared to 7A on the HC3-HP-AC240V-F. This higher rating provides additional safety margin and allows the substitute to handle applications at or below the original 7A specification without derating.

Q: Does the operating temperature range difference affect substitution?

A: The LY3-0-AC240 operates from -25°C to 55°C, compared to -50°C to 70°C for the HC3-HP-AC240V-F. Substitution is valid only if the application environment remains within the -25°C to 55°C window. Applications requiring the full -50°C to 70°C range require alternative solutions.

Q: Why does the LY3-0-AC240 have a higher coil current specification?

A: The LY3-0-AC240 draws 8mA coil current versus 5mA for the HC3-HP-AC240V-F. This difference reflects design variations between manufacturers but does not affect substitution validity. The 240VAC coil voltage remains identical, and the higher current draw is within acceptable design tolerance for general purpose relay applications.

Q: Are there packaging considerations for this substitution?

A: The HC3-HP-AC240V-F is available in standard packaging, while the LY3-0-AC240 is supplied in bulk packaging. Both use identical PC pin termination and through-hole mounting, ensuring mechanical compatibility on printed circuit boards. Verify bulk packaging meets procurement and handling requirements for your application.

Q: What compliance certifications apply to the substitute part?

A: The LY3-0-AC240 carries RoHS compliance certification, meeting modern regulatory requirements for hazardous substance restrictions. Both parts are classified under ECCN EAR99 and HTSUS 8536.49.0075 for export and tariff purposes.
