HC3-HTM-AC200V-F Equivalent & Substitute Parts

Part Overview

The HC3-HTM-AC200V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with a 200VAC coil. This chassis mount relay is rated for 7A switching current at 250VAC maximum and operates with a 6mA coil current. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where this relay is specified in legacy equipment.

Substitute Part Grouping Explanation

Substitution of the HC3-HTM-AC200V-F is determined by the following critical parameters:

Contact Configuration: 3PDT (3 Form C) contact form is mandatory for functional equivalence
Coil Voltage Class: 200VAC nominal coil voltage with acceptable operating range between 160VAC (must operate) and 220VAC nominal
Current Rating: Minimum 7A contact rating required; higher ratings are acceptable
Switching Voltage: 250VAC maximum switching capability required
Mounting and Termination: Chassis mount with plug-in termination style
Coil Type: Non-latching operation required
Relay Type: General purpose classification

The LY3F-AC200/220 from Omron Automation and Safety meets these substitution criteria with compatible electrical and mechanical parameters.

Engineering Selection Recommendations

The LY3F-AC200/220 is a suitable substitute for the HC3-HTM-AC200V-F based on the following factors:

Product Status: The Panasonic HC3-HTM-AC200V-F is obsolete, while the Omron LY3F-AC200/220 is active and in current production, ensuring long-term availability and supply chain continuity.
Electrical Compatibility: Both relays share identical 3PDT contact configuration and non-latching coil type. The Omron part operates at 220VAC nominal coil voltage, which is compatible with 200VAC supply circuits within standard industrial voltage tolerances.
Current Rating: The Omron relay is rated for 10A, exceeding the 7A requirement of the Panasonic part. This provides additional margin for switching capacity.
Switching Voltage: Both relays support 250VAC maximum switching voltage, meeting the electrical switching requirements.
Compliance: The Omron LY3F-AC200/220 is RoHS compliant, meeting modern environmental and regulatory standards.
Critical Differences: The Omron substitute has a narrower operating temperature range (-25°C to 55°C versus -50°C to 70°C) and slightly longer response times (25ms versus 20ms). Verify these parameters against specific application requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can the LY3F-AC200/220 directly replace the HC3-HTM-AC200V-F in existing equipment?

A: The LY3F-AC200/220 is electrically and mechanically compatible for most applications. However, verify that your equipment operates within the Omron relay's temperature range (-25°C to 55°C) and that the slightly longer response time (25ms versus 20ms) does not affect system timing requirements.

Q: What is the difference between 200VAC and 220VAC coil voltage?

A: The 220VAC coil voltage of the Omron relay is compatible with 200VAC supply circuits. Industrial power supplies typically operate within ±10% voltage tolerance, making 220VAC acceptable for 200VAC nominal systems. Verify your actual supply voltage before installation.

Q: Does the higher coil current of the Omron relay (9.9mA versus 6mA) affect circuit design?

A: The Omron relay draws 9.9mA compared to the Panasonic relay's 6mA. Verify that your control circuit can supply this additional current without exceeding component ratings or causing voltage drop issues.

Q: Are there any packaging or termination differences?

A: Both relays feature chassis mount construction with plug-in termination. The Panasonic part specifies 11-pin termination, while the Omron part uses standard plug-in termination. Confirm physical pin compatibility with your socket or wiring configuration before installation.

Q: What is the significance of the Panasonic relay being obsolete?

A: Obsolete status indicates the Panasonic HC3-HTM-AC200V-F is no longer manufactured. The Omron LY3F-AC200/220 is an active product in current production, ensuring availability for replacement and future procurement needs.

Q: Is the Omron relay RoHS compliant?

A: Yes, the LY3F-AC200/220 is RoHS compliant. The Panasonic part's compliance status is not specified in available documentation.
