HC3-H-AC200V-F Equivalent & Substitute Parts

Part Overview

The HC3-H-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 socketable relay is rated for 7A at 250VAC maximum switching voltage and operates with a 6mA coil current. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

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

Contact configuration must remain 3PDT (3 Form C) to maintain circuit switching topology. Coil voltage must operate within the system's AC supply range; the 200VAC specification allows substitution with 220VAC coils where the must-operate and must-release voltage thresholds remain compatible. Contact current rating must equal or exceed 7A to handle the load without derating. Mounting type must be socketable to ensure mechanical compatibility with existing relay bases. Switching voltage rating must support 250VAC operation.

The LY3-AC200/220 from Omron Automation and Safety meets these substitution criteria through equivalent contact form, socketable mounting, compatible voltage operating windows, and superior current rating of 10A.

Parameter Comparison

Engineering Selection Recommendations

The LY3-AC200/220 is the qualified substitute for the HC3-H-AC200V-F based on the following factors:

The LY3-AC200/220 maintains active product status with current manufacturing support, eliminating supply chain risk associated with the obsolete HC3-H-AC200V-F. Both relays are RoHS compliant and carry identical ECCN classification (EAR99), ensuring regulatory consistency. The Omron substitute provides superior contact current rating (10A versus 7A), offering operational margin in the application. Socketable mounting and 3PDT contact configuration ensure direct mechanical and electrical compatibility. The 220VAC coil voltage operates within acceptable tolerance of the 200VAC original specification, with must-operate and must-release voltage parameters remaining within functional margins for AC supply systems.

The LY3-AC200/220 exhibits slightly extended response times (25ms versus 20ms) and narrower operating temperature range (-25°C to 55°C versus -50°C to 70°C), which must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the LY3-AC200/220 directly replace the HC3-H-AC200V-F in existing sockets?

A: Yes. Both relays feature socketable mounting with plug-in termination, enabling direct mechanical installation in existing relay bases designed for the HC3-H-AC200V-F.

Q: Is the 220VAC coil voltage compatible with a 200VAC supply?

A: The LY3-AC200/220 is rated for 220VAC nominal operation. In systems supplying 200VAC, the relay will operate below nominal voltage. The must-operate voltage of 176VAC confirms the relay will energize reliably at 200VAC supply. System voltage stability and tolerance must be verified to ensure consistent operation.

Q: What are the differences in response time between these relays?

A: The HC3-H-AC200V-F operates and releases in 20ms, while the LY3-AC200/220 requires 25ms for both operations. Applications with timing-critical switching sequences must account for this 5ms difference.

Q: Does the LY3-AC200/220 support the full temperature range of the original relay?

A: No. The LY3-AC200/220 operates from -25°C to 55°C, compared to the HC3-H-AC200V-F range of -50°C to 70°C. Applications requiring operation below -25°C or above 55°C must evaluate alternative substitutes or confirm the LY3-AC200/220 operates within the actual system temperature envelope.

Q: Are there packaging differences between these relays?

A: The HC3-H-AC200V-F uses 11-pin plug-in termination, while the LY3-AC200/220 uses standard plug-in termination. Pin configuration compatibility with the relay base must be verified before installation.

Q: What is the current rating advantage of the LY3-AC200/220?

A: The LY3-AC200/220 is rated for 10A contact current versus 7A for the HC3-H-AC200V-F. This 3A margin provides operational headroom for applications operating near the original relay's current limit.
