HC2E-HTM-AC200V-F Equivalent & Substitute Parts

Part Overview

The HC2E-HTM-AC200V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 200VAC coil. This chassis mount relay is rated for 3A switching capacity at 250VAC maximum and operates with a 6.6mA coil current. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications where this relay is specified in legacy equipment.

Substitute Part Grouping Explanation

The LY2F-AC200/220 from Omron Automation and Safety qualifies as a functional substitute for the HC2E-HTM-AC200V-F based on the following critical parameters:

Contact Configuration Match: Both relays feature DPDT (2 Form C) contact forms, enabling identical switching logic and circuit topology compatibility.

Coil Voltage Compatibility: The HC2E operates at 200VAC, while the LY2F operates at 220VAC. These voltages fall within the same AC supply class and are compatible in systems designed for 200-240VAC operation ranges.

Non-Latching Coil Type: Both relays use non-latching coil designs, maintaining identical operational behavior and control signal requirements.

Relay Classification: Both are general purpose relays with chassis mount configurations and plug-in termination styles, supporting direct mechanical and electrical integration.

Switching Voltage Rating: Both relays support 250VAC maximum switching voltage, meeting the same load switching requirements.

Coil Current Characteristics: The LY2F operates at 5.8mA coil current compared to the HC2E's 6.6mA, representing a 12% reduction in control power consumption while maintaining functional operation.

Sealed Construction: Both relays feature sealed designs, providing equivalent environmental protection.

Parameter Comparison

Engineering Selection Recommendations

The LY2F-AC200/220 is an active product from a major automation manufacturer, providing supply continuity for applications currently using the obsolete HC2E-HTM-AC200V-F. The substitute meets all critical functional requirements: identical DPDT contact configuration, compatible AC coil voltage class, and equivalent switching voltage ratings.

The LY2F offers enhanced current rating (10A versus 3A), providing design margin for applications with moderate load increases. The substitute's RoHS compliance status supports modern procurement and environmental regulatory requirements, whereas the HC2E's compliance status is not specified.

Timing differences exist: the LY2F operates and releases 5ms slower than the HC2E. Applications with strict timing constraints below 25ms should evaluate this parameter against system requirements. The LY2F's operating temperature range (-25°C to 55°C) is narrower than the HC2E (-40°C to 60°C), requiring verification for extreme temperature environments.

The LY2F's lower coil resistance (12.95 kOhms versus 33.33 kOhms) results in reduced control circuit impedance. Existing drive circuits designed for the HC2E's higher impedance should be evaluated for compatibility with the substitute's lower impedance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LY2F-AC200/220 directly replace the HC2E-HTM-AC200V-F in existing equipment?

A: Functional replacement is possible due to matching DPDT contact configuration and compatible AC coil voltage class. However, physical verification of mounting compatibility, termination pin alignment, and control circuit impedance matching is required before installation.

Q: What is the significance of the 20VAC difference between the HC2E's 200VAC and LY2F's 220VAC coil ratings?

A: Both voltages operate within the 200-240VAC AC supply class. The 220VAC rating is standard in many international markets. Substitution is valid in systems designed for this voltage range. Verify actual supply voltage in the application before selection.

Q: Why does the LY2F have a higher current rating (10A) than the HC2E (3A)?

A: The LY2F is designed for higher load switching capacity. This provides design margin and does not prevent substitution in applications requiring only 3A switching. The higher rating ensures adequate contact life and thermal performance.

Q: Are there timing implications when substituting the LY2F for the HC2E?

A: Yes. The LY2F operates and releases 5ms slower (25ms versus 20ms). Applications with timing-critical control sequences should evaluate whether this 25% increase in switching time affects system performance.

Q: What is the impact of the LY2F's lower coil resistance on the control circuit?

A: The LY2F's 12.95 kOhms resistance is significantly lower than the HC2E's 33.33 kOhms. This reduces impedance and may increase coil current draw from the control circuit. Existing drive circuits should be evaluated for current capacity compatibility.

Q: Does the LY2F's RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory advantage for new designs and modern procurement environments. It does not prevent substitution but indicates the LY2F meets current environmental standards, whereas the HC2E's compliance status is unspecified.

Q: How do the operating temperature ranges compare?

A: The HC2E operates from -40°C to 60°C, while the LY2F operates from -25°C to 55°C. The HC2E has a wider range. Applications operating below -25°C or above 55°C require the HC2E or alternative solutions.

Q: What packaging considerations apply to this substitution?

A: The HC2E uses 8-pin plug-in termination, while the LY2F uses plug-in termination without specified pin count. Physical socket compatibility must be verified before installation to ensure proper electrical connection.
