HC2-HTM-AC200V-F Equivalent & Substitute Parts

Part Overview

The HC2-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 voltage and 7A contact rating. This relay is designed for chassis mount applications with plug-in, 8-pin termination. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications where continued operation is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-HTM-AC200V-F is determined by the following critical parameters:

Primary Compatibility Criteria:

• Contact form must be DPDT (2 Form C) to maintain circuit switching functionality
• Coil voltage must operate within the system's AC supply range (200VAC nominal)
• Contact current rating must equal or exceed 7A to handle the load
• Mounting type must be chassis mount with compatible termination
• Relay type must be general purpose, non-latching

Acceptable Variation Parameters:

• Coil voltage tolerance: Substitute coil voltages within ±10% of the original 200VAC specification are acceptable (180VAC–220VAC range)
• Contact current rating: Substitutes with equal or higher current ratings are acceptable
• Switching voltage: Must meet or exceed 250VAC maximum requirement
• Operating temperature range: Substitutes with equal or wider temperature ranges are acceptable
• Coil current and resistance: Minor variations acceptable if coil voltage compatibility is maintained

The LY2F-AC200/220 from Omron Automation and Safety meets these criteria with a 220VAC coil voltage (within acceptable tolerance), DPDT contact form, 10A contact rating (exceeds 7A requirement), and chassis mount configuration.

Parameter Comparison

Engineering Selection Recommendations

The LY2F-AC200/220 is a suitable substitute for the obsolete HC2-HTM-AC200V-F based on the following engineering factors:

Functional Compatibility: Both relays share identical contact form (DPDT), relay type (general purpose, non-latching), and mounting configuration (chassis mount, plug-in termination). The substitute's 220VAC coil voltage operates within acceptable tolerance of the original 200VAC specification for AC supply systems.

Performance Adequacy: The LY2F-AC200/220 provides a 10A contact rating, which exceeds the original 7A requirement, ensuring adequate margin for the intended load. Switching voltage specifications meet or exceed the original requirement.

Product Status and Compliance: The LY2F-AC200/220 is an active product currently manufactured by Omron Automation and Safety, ensuring availability and supply chain continuity. The substitute is RoHS compliant, meeting modern environmental and regulatory standards.

Operational Considerations: The substitute operates within a narrower temperature range (-25°C ~ 55°C versus -50°C ~ 70°C). Applications requiring operation below -25°C or above 55°C require verification of environmental conditions. Operate and release times are marginally longer (25 ms versus 20 ms), which is acceptable for general purpose relay applications unless timing-critical switching is required.

Termination Verification: Both relays use plug-in termination; however, physical pin configuration and socket compatibility must be verified during installation to ensure proper mechanical fit and electrical connection.

Frequently Asked Questions (FAQ)

Q: Can the LY2F-AC200/220 directly replace the HC2-HTM-AC200V-F without circuit modifications?

A: The LY2F-AC200/220 is functionally compatible for most general purpose relay applications. The 220VAC coil voltage is within acceptable tolerance for 200VAC systems. However, verify that the plug-in termination socket accommodates the substitute relay's pin configuration, as physical compatibility must be confirmed before installation.

Q: What is the significance of the coil voltage difference (200VAC versus 220VAC)?

A: The 220VAC coil voltage of the substitute is within ±10% tolerance of the original 200VAC specification. This variation is acceptable for AC supply systems, as industrial AC supplies typically operate within ±10% of nominal voltage. The substitute will operate reliably in circuits designed for 200VAC coils.

Q: Why does the substitute have a higher current rating (10A versus 7A)?

A: A higher contact current rating provides additional safety margin and does not negatively affect circuit operation. The substitute can safely handle loads up to 10A, while the original was rated for 7A. This is an advantage for applications with potential load growth or where additional margin is desired.

Q: Are there any timing differences between the original and substitute relays?

A: The LY2F-AC200/220 has slightly longer operate and release times (25 ms versus 20 ms). For general purpose relay applications, this 5 ms difference is typically negligible. Applications requiring precise timing control should evaluate whether this difference affects system performance.

Q: What is the operating temperature range difference, and does it matter?

A: The original HC2-HTM-AC200V-F operates from -50°C to 70°C, while the substitute operates from -25°C to 55°C. The substitute has a narrower range. If your application requires operation below -25°C or above 55°C, the substitute may not be suitable. For standard industrial environments (typically 0°C to 50°C), the substitute is adequate.

Q: Is the contact material difference (gold plating) significant?

A: The original includes gold plating on silver alloy contacts, while the substitute uses silver alloy without specified gold plating. Both materials are suitable for general purpose relay applications. Gold plating provides enhanced corrosion resistance in harsh environments; if your application requires this protection, contact material should be evaluated.

Q: What does RoHS compliance mean for the substitute?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the substitute meets environmental standards restricting lead, mercury, cadmium, and other hazardous materials. This is advantageous for modern applications and regulatory compliance, particularly in industries with environmental requirements.

Q: How do I verify physical compatibility before installation?

A: Obtain the mechanical drawings and pin configuration diagrams for both relays. Verify that the plug-in socket in your equipment accommodates the LY2F-AC200/220's pin layout and spacing. Contact the relay manufacturers or distributors for detailed dimensional specifications if drawings are unavailable.
