HC4-HPL-AC120V Equivalent & Substitute Parts

Part Overview

The HC4-HPL-AC120V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with 120VAC coil voltage and 5A contact rating. This through-hole mounted relay is designed for industrial control applications requiring multiple independent switching circuits. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4-HPL-AC120V are identified based on the following critical parameters that must align for functional equivalence:

• Contact Configuration: 4PDT (4 Form C) — provides four independent switching circuits with identical electrical characteristics
• Coil Voltage: 120VAC — ensures direct compatibility with existing control circuits without modification
• Mounting Type: Through Hole — maintains mechanical compatibility with printed circuit board layouts
• Termination Style: PC Pin — ensures proper connection to PCB traces without adapter requirements
• Coil Type: Non Latching — maintains operational behavior for momentary control applications
• Must Operate Voltage: 96VAC minimum — ensures reliable operation within specified voltage tolerance
• Must Release Voltage: 36VAC maximum — ensures predictable de-energization behavior

The MY4N-02-AC110/120 from Omron Automation and Safety meets all critical substitution criteria. While the contact rating differs (3A versus 5A), this represents a derating that maintains compatibility for applications within the 3A limit.

Parameter Comparison

Engineering Selection Recommendations

The MY4N-02-AC110/120 is the qualified substitute for the HC4-HPL-AC120V based on the following engineering criteria:

Functional Compatibility: Both relays share identical contact configuration (4PDT), coil voltage (120VAC), mounting type (through hole), and termination style (PC pin). Timing characteristics (20ms operate and release times) and voltage thresholds (96VAC must-operate, 36VAC must-release) are identical.

Product Status Advantage: The MY4N-02-AC110/120 is active in production, ensuring long-term availability and supply chain continuity compared to the obsolete HC4-HPL-AC120V.

Compliance Status: The MY4N-02-AC110/120 carries RoHS Compliance certification, meeting modern regulatory requirements for new equipment designs and system upgrades.

Current Rating Consideration: The substitute part is rated for 3A maximum contact current, compared to 5A for the original. This represents a derating and is suitable for applications where the actual switching current does not exceed 3A per contact.

Frequently Asked Questions (FAQ)

Q: Can the MY4N-02-AC110/120 directly replace the HC4-HPL-AC120V without PCB modifications?

A: Yes. Both relays use identical through-hole PC pin termination and share the same contact configuration (4PDT). No PCB layout changes are required for mechanical and electrical connection.

Q: What is the significance of the 3A versus 5A contact rating difference?

A: The MY4N-02-AC110/120 is rated for a maximum of 3A per contact, while the HC4-HPL-AC120V is rated for 5A. The substitute is suitable for applications where the actual switching current per contact remains at or below 3A. Applications requiring switching currents between 3A and 5A cannot use this substitute.

Q: Are the coil voltage specifications identical?

A: Yes. Both relays operate on 120VAC coil voltage with identical must-operate (96VAC) and must-release (36VAC) thresholds, ensuring compatible control circuit integration.

Q: How do the operating temperature ranges compare?

A: The MY4N-02-AC110/120 operates across -55°C to 70°C, which encompasses the HC4-HPL-AC120V range of -50°C to 60°C. The substitute provides extended low-temperature capability.

Q: What is the difference in contact material between these relays?

A: The HC4-HPL-AC120V uses Silver Nickel (AgNi) contacts, while the MY4N-02-AC110/120 uses Silver (Ag) contacts. Both materials are suitable for general-purpose switching applications at the specified voltage and current levels.

Q: Does the lower coil current of the MY4N-02-AC110/120 affect compatibility?

A: No. The lower coil current (8.4mA versus 10.9mA) indicates improved efficiency and does not affect control circuit compatibility. The relay will operate reliably with standard 120VAC control circuits.

Q: Is the MY4N-02-AC110/120 suitable for new equipment designs?

A: Yes. The MY4N-02-AC110/120 is an active product with RoHS Compliance certification, making it appropriate for new equipment designs and system upgrades requiring modern regulatory compliance.
