HC4E-HTM-AC240V Equivalent & Substitute Parts

Part Overview

The HC4E-HTM-AC240V is a general purpose relay manufactured by Panasonic Electric Works, featuring a 4PDT (4 Form C) contact configuration with a 240VAC coil and 2A contact rating. This socketable relay is designed for industrial control applications requiring multiple independent switching circuits. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC4E-HTM-AC240V are identified based on the following critical parameters that must align for functional compatibility:

• Contact Configuration: 4PDT (4 Form C) — maintains identical switching topology
• Coil Voltage: 240VAC — ensures direct coil compatibility without external voltage conversion
• Mounting Type: Socketable — allows direct mechanical and electrical replacement in existing socket bases
• Termination Style: Plug In — maintains compatibility with existing wiring and socket infrastructure
• Coil Type: Non Latching — preserves operational behavior (relay returns to de-energized state upon coil de-excitation)
• Must Operate Voltage: 192VAC minimum — ensures reliable operation within specified voltage tolerance
• Must Release Voltage: 72VAC maximum — defines voltage threshold for relay de-energization

The substitute part MY4N AC220/240 (S) meets all critical substitution criteria. While the contact rating is higher (3A versus 2A), this represents an upgrade in capability and does not compromise compatibility in applications designed for the original 2A specification.

Parameter Comparison

Engineering Selection Recommendations

The MY4N AC220/240 (S) is a direct functional substitute for the HC4E-HTM-AC240V. Both relays share identical contact configuration, coil voltage, mounting type, and switching characteristics. The substitute part offers the following advantages:

• Active Product Status: The MY4N AC220/240 (S) is currently in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Current Rating: The 3A contact rating provides additional margin over the original 2A specification, suitable for applications requiring higher switching capacity.
• Expanded Operating Temperature Range: The -55°C to 70°C range exceeds the original -40°C to 60°C specification, enabling deployment in more demanding thermal environments.
• RoHS Compliance: The substitute part meets RoHS requirements, supporting compliance with modern environmental and regulatory standards.
• Lower Coil Current: The 4.2mA coil current is slightly lower than the original 5mA, reducing power consumption in control circuits.

Frequently Asked Questions (FAQ)

Q: Can the MY4N AC220/240 (S) be directly installed in the socket designed for the HC4E-HTM-AC240V?

A: Yes. Both relays feature socketable mounting with plug-in termination, enabling direct mechanical and electrical replacement without socket modification.

Q: Does the higher 3A contact rating of the MY4N AC220/240 (S) affect compatibility with circuits designed for 2A?

A: No. The higher contact rating represents increased capability and does not compromise operation in circuits specified for 2A switching. The relay will function correctly in all applications where the original 2A relay was used.

Q: Are the coil voltage and operating voltage thresholds identical between the two relays?

A: Yes. Both relays operate on 240VAC coil voltage with identical must-operate (192VAC) and must-release (72VAC) voltage thresholds, ensuring equivalent performance in voltage-sensitive applications.

Q: What is the significance of the MY4N AC220/240 (S) being RoHS compliant?

A: RoHS compliance indicates the substitute part meets restrictions on hazardous substances, supporting deployment in systems subject to environmental regulations and modern procurement standards.

Q: Are the switching times identical between the HC4E-HTM-AC240V and MY4N AC220/240 (S)?

A: Yes. Both relays have 20ms operate time and 20ms release time, maintaining identical switching speed characteristics for timing-critical control applications.
