HC3-HP-DC110V Equivalent & Substitute Parts

Part Overview

The HC3-HP-DC110V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with a 110VDC coil. This through-hole mounted relay is designed for applications requiring simultaneous switching of three independent circuits. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC3-HP-DC110V is determined by strict alignment of the following critical parameters:

• Coil Voltage: Must be 110VDC to ensure direct compatibility with existing power supply circuits
• Contact Form: Must be 3PDT (3 Form C) to maintain identical switching functionality across three independent circuits
• Mounting Type: Must be through-hole to ensure mechanical compatibility with existing PCB layouts
• Termination Style: Must be PC Pin to match existing solder pad configurations
• Must Operate Voltage and Must Release Voltage: Must fall within or match the specified ranges (88 VDC operate, 11 VDC release) to ensure reliable actuation under system voltage conditions
• Operating Temperature Range: Must encompass or exceed the original specification to maintain performance across the intended thermal environment

The MY3-02-DC100/110 manufactured by Omron Automation and Safety meets these substitution criteria and is classified as an active product with current availability.

Parameter Comparison

Engineering Selection Recommendations

The MY3-02-DC100/110 is a suitable substitute for the obsolete HC3-HP-DC110V based on the following factors:

Product Status: The MY3-02-DC100/110 is an active product with confirmed current inventory (1061 pcs), ensuring long-term availability and supply chain continuity compared to the obsolete HC3-HP-DC110V.

Electrical Compatibility: Both relays share identical coil voltage (110VDC), contact form (3PDT), must-operate voltage (88 VDC), and must-release voltage (11 VDC) specifications. These parameters ensure functional equivalence in control circuits.

Mechanical Compatibility: Both relays feature through-hole mounting with PC pin termination, enabling direct replacement in existing PCB layouts without modification.

Regulatory Compliance: The MY3-02-DC100/110 is RoHS compliant, meeting modern environmental and regulatory requirements. The HC3-HP-DC110V is REACH unaffected, indicating no conflict with chemical substance restrictions.

Design Considerations: The MY3-02-DC100/110 has a lower contact rating (5 A versus 7 A) and longer switching times (20 ms operate and release versus 10 ms and 5 ms). Applications requiring the full 7 A contact rating or faster switching response must evaluate whether the reduced specifications are acceptable for the intended circuit function.

Frequently Asked Questions (FAQ)

Q: Can the MY3-02-DC100/110 directly replace the HC3-HP-DC110V without PCB modification?

A: Yes. Both relays share identical coil voltage, contact form, mounting type, and termination style. Direct substitution is mechanically and electrically feasible without PCB redesign.

Q: What is the significance of the lower 5 A contact rating on the MY3-02-DC100/110 compared to the 7 A rating of the HC3-HP-DC110V?

A: The contact rating defines the maximum continuous current each relay contact can safely switch. Applications operating at currents between 5 A and 7 A must confirm that the MY3-02-DC100/110 meets the circuit's current requirements. If the application requires currents exceeding 5 A, alternative substitutes must be evaluated.

Q: Why are the switching times different between these two relays?

A: Operate time and release time are inherent to relay design and manufacturing. The MY3-02-DC100/110 has longer switching times (20 ms) compared to the HC3-HP-DC110V (10 ms operate, 5 ms release). Applications with strict timing requirements must confirm that the extended switching times do not impact system performance.

Q: Are there packaging differences between these relays?

A: The HC3-HP-DC110V is packaged individually, while the MY3-02-DC100/110 is supplied in bulk packaging. Both are through-hole mounted components with identical footprints and pin configurations.

Q: What compliance certifications apply to each relay?

A: The MY3-02-DC100/110 is RoHS compliant, meeting restrictions on hazardous substances in electrical and electronic equipment. The HC3-HP-DC110V is REACH unaffected, indicating no conflict with chemical substance regulations. Both relays carry the same ECCN (EAR99) and HTSUS (8536.49.0050) classifications.

Q: Is the MY3-02-DC100/110 suitable for the full operating temperature range of the HC3-HP-DC110V?

A: The MY3-02-DC100/110 operating temperature range (-55°C ~ 70°C) exceeds the HC3-HP-DC110V specification (-50°C ~ 70°C). The substitute provides extended low-temperature performance, ensuring compatibility across the original thermal envelope and beyond.
