HC2E-L-AC48V-F Equivalent & Substitute Parts

Part Overview

The HC2E-L-AC48V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 48VAC coil. This socketable relay is designed for applications requiring 3A contact rating at 250VAC maximum switching voltage. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2E-L-AC48V-F is determined by the following critical parameters:

Contact Configuration: Both the main part and substitute must provide DPDT (2 Form C) contact arrangement to maintain circuit switching capability.

Coil Voltage Compatibility: The substitute coil voltage must operate within the system's 48VAC supply specification. The LY2N AC50 operates at 50VAC, which falls within acceptable tolerance for AC coil relays in industrial applications where ±10% voltage variation is standard.

Contact Rating: The substitute must support the required current-switching capacity. The HC2E-L-AC48V-F requires 3A minimum; the LY2N AC50 provides 10A, exceeding this requirement.

Mounting and Termination: Both relays feature socketable mounting with plug-in termination, ensuring mechanical and electrical compatibility in existing socket installations.

Coil Type: Both relays are non-latching, maintaining identical operational behavior.

Switching Voltage: Both relays support 250VAC maximum switching voltage, ensuring compatibility with the application's load voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

The LY2N AC50 serves as a functional equivalent for the obsolete HC2E-L-AC48V-F based on the following engineering criteria:

Electrical Compatibility: Both relays provide identical DPDT contact configuration and non-latching coil operation. The 50VAC coil voltage of the LY2N AC50 is compatible with 48VAC supply systems, as AC relay coils typically tolerate ±10% voltage variation. The substitute's 10A contact rating exceeds the original 3A requirement, providing additional margin for load current.

Mechanical Compatibility: Both relays feature socketable mounting with plug-in termination, enabling direct installation in existing HC-series relay sockets without modification.

Operational Differences: The LY2N AC50 exhibits 5 millisecond longer operate and release times (25 ms versus 20 ms). This difference is acceptable for general purpose relay applications where switching speed is not a critical timing parameter.

Temperature Range Consideration: The LY2N AC50 operates over -25°C to 55°C, which is narrower than the original -40°C to 60°C range. Applications requiring operation below -25°C or above 55°C must verify alternative substitutes or confirm that the LY2N AC50 meets the specific environmental requirements.

Product Availability: The LY2N AC50 is currently in active production with 1124 units in stock, ensuring long-term availability compared to the obsolete HC2E-L-AC48V-F.

Compliance: The LY2N AC50 is RoHS compliant, meeting modern environmental and regulatory standards for new equipment designs and replacements.

Frequently Asked Questions (FAQ)

Q: Can the LY2N AC50 be directly installed in place of the HC2E-L-AC48V-F?

A: Yes, provided the application's operating temperature range does not exceed -25°C to 55°C. Both relays feature identical DPDT contact configuration, socketable mounting, and plug-in 8-pin termination, enabling direct socket replacement without circuit modification.

Q: What is the significance of the 2VAC coil voltage difference between 48VAC and 50VAC?

A: AC relay coils are designed to operate within standard voltage tolerance bands, typically ±10%. The 2VAC difference represents approximately 4% variation, well within acceptable operating parameters for general purpose relays. No circuit modification is required.

Q: Does the higher 10A contact rating of the LY2N AC50 affect compatibility?

A: No. A higher contact rating indicates the substitute can safely handle greater current loads than the original 3A specification. This provides additional safety margin and does not compromise compatibility with applications designed for 3A operation.

Q: Are there any timing considerations when substituting the LY2N AC50?

A: The LY2N AC50 has 5 millisecond longer operate and release times (25 ms versus 20 ms). For general purpose relay applications, this difference is negligible. Applications with critical timing requirements below 25 milliseconds must verify that the substitute meets specific switching speed specifications.

Q: What is the impact of the narrower operating temperature range of the LY2N AC50?

A: The LY2N AC50 operates from -25°C to 55°C, compared to the original -40°C to 60°C. If the application requires operation below -25°C or above 55°C, the substitute is not suitable. Verify the actual operating environment before selection.

Q: Is the LY2N AC50 RoHS compliant?

A: Yes. The LY2N AC50 is RoHS compliant, meeting environmental and regulatory requirements for modern equipment. The original HC2E-L-AC48V-F RoHS status is not specified in available documentation.
