HC4ED-PL-AC120V Equivalent & Substitute Parts

Part Overview

The HC4ED-PL-AC120V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with a 120VAC coil. This through-hole mounted relay is designed for applications requiring simultaneous switching of four independent circuits. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC4ED-PL-AC120V is determined by strict alignment of the following critical parameters:

• Contact Configuration: 4PDT (4 Form C) contact form is mandatory for functional equivalence
• Coil Voltage: 120VAC coil voltage must match to ensure proper circuit integration
• Mounting Type: Through-hole mounting is required for PCB compatibility
• Coil Type: Non-latching operation must be preserved
• Termination Style: PC pin termination ensures mechanical and electrical compatibility
• Operating Voltage Range: Must operate at 96 VAC minimum and release at 36 VAC maximum

The MY4N-02-AC110/120 manufactured by Omron Automation and Safety satisfies all mandatory substitution criteria. While the contact rating differs (3 A versus 1 A), this represents an upgrade in capability and does not prevent substitution in applications designed for the original 1 A specification.

Engineering Selection Recommendations

The MY4N-02-AC110/120 is the qualified substitute for the obsolete HC4ED-PL-AC120V. Selection is based on the following factors:

Product Status: The HC4ED-PL-AC120V is obsolete, creating supply chain risk. The MY4N-02-AC110/120 is active and maintains current manufacturing status, ensuring long-term availability.

Compliance and Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8536.49.0050) classifications. The MY4N-02-AC110/120 carries RoHS compliance certification, meeting modern regulatory requirements.

Functional Compatibility: All critical electrical parameters align, including coil voltage, contact configuration, operating voltage thresholds, and switching characteristics. The substitute provides enhanced contact current rating (3 A versus 1 A) and extended operating temperature range (-55°C to 70°C versus -40°C to 60°C), representing performance improvements over the original specification.

Frequently Asked Questions (FAQ)

Q: Can the MY4N-02-AC110/120 directly replace the HC4ED-PL-AC120V in existing applications?

A: Yes. Both relays share identical coil voltage (120VAC), contact configuration (4PDT), mounting type (through-hole), and termination style (PC pin). The substitute operates within the same voltage thresholds and timing specifications. The higher contact current rating of the substitute does not prevent operation in circuits designed for 1 A switching.

Q: What are the key differences between these two relays?

A: The primary differences are contact current rating (1 A versus 3 A), operating temperature range (-40°C to 60°C versus -55°C to 70°C), contact material composition (AgNi/Au versus Ag), and product status (obsolete versus active). The substitute also supports both AC and DC switching voltages, whereas the original specifies AC only.

Q: Are there any packaging considerations when substituting these parts?

A: Both relays use through-hole PC pin termination and are designed for PCB mounting. The HC4ED-PL-AC120V was supplied in standard packaging, while the MY4N-02-AC110/120 is available in bulk packaging. Pin configuration and footprint compatibility should be verified against the specific PCB design.

Q: Does the lower coil current of the substitute affect circuit design?

A: The MY4N-02-AC110/120 requires 8.4 mA coil current compared to 10.9 mA for the original. This represents a reduction in power consumption and may improve driver circuit efficiency. Existing driver circuits designed for 10.9 mA will operate reliably with the lower current requirement.

Q: Is RoHS compliance a factor in selecting the substitute?

A: The MY4N-02-AC110/120 is RoHS compliant, meeting current environmental and regulatory standards. If your application or end-market requires RoHS certification, the substitute satisfies this requirement while the obsolete original part may not.
