HC2-H-AC115V Equivalent & Substitute Parts

Part Overview

The Panasonic Electric Works HC2-H-AC115V is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 115VAC coil voltage and 7A contact current. This socketable relay is designed for standard industrial switching applications. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HC2-H-AC115V are qualified based on the following critical parameters:

Primary Compatibility Criteria:

• Contact form must be DPDT (2 Form C)
• Mounting type must be socketable with plug-in termination
• Coil type must be non-latching
• Coil voltage must be compatible with 115VAC operation (acceptable range: 110-120VAC nominal)
• Contact rating must support minimum 7A switching capacity
• Maximum switching voltage must be at least 250VAC
• Operating temperature range must encompass or overlap the original specification

Identified Substitute Parts:

• KHAU-11A11-120 (TE Connectivity Potter & Brumfield Relays)
• MY2 AC110/120 (S) (Omron Automation and Safety)

Both substitutes meet the core functional requirements of DPDT socketable relay configuration with compatible coil voltage ratings and plug-in termination. Contact current ratings differ from the original specification and must be evaluated for application requirements.

Engineering Selection Recommendations

KHAU-11A11-120 (TE Connectivity Potter & Brumfield Relays):

• Active product status ensures ongoing availability and supply chain continuity
• RoHS3 compliant, meeting current environmental regulations
• Contact rating of 3A is lower than the original 7A specification; suitable only for applications requiring 3A or less
• Coil voltage of 120VAC is compatible with 115VAC nominal systems
• Must operate voltage of 102VAC is higher than the original 92VAC, requiring verification in low-voltage conditions

MY2 AC110/120 (S) (Omron Automation and Safety):

• Active product status with established supply availability
• RoHS compliant, meeting environmental standards
• Contact rating of 5A is lower than the original 7A specification; suitable for applications requiring 5A or less
• Coil voltage of 120VAC is compatible with 115VAC nominal systems
• Must operate voltage of 96VAC is closer to the original specification, providing better low-voltage performance
• Operating temperature range of -55°C ~ 70°C exceeds the original specification, offering extended cold-temperature capability

Frequently Asked Questions (FAQ)

Q: Can KHAU-11A11-120 directly replace HC2-H-AC115V in all applications? A: No. The KHAU-11A11-120 has a contact rating of 3A, which is lower than the original 7A rating. It is suitable only for applications where the switching current does not exceed 3A. The higher must-operate voltage (102VAC vs. 92VAC) may also affect performance in systems with lower supply voltages.

Q: Can MY2 AC110/120 (S) directly replace HC2-H-AC115V in all applications? A: No. The MY2 AC110/120 (S) has a contact rating of 5A, which is lower than the original 7A rating. It is suitable only for applications where the switching current does not exceed 5A. Applications requiring the full 7A capacity require evaluation of alternative solutions.

Q: What is the significance of the coil voltage difference (115VAC vs. 120VAC)? A: Both substitute parts operate at 120VAC nominal coil voltage, which is compatible with 115VAC systems in standard industrial applications. The voltage difference of 5V is within typical tolerance ranges for AC power distribution.

Q: Are the socketable mounting and plug-in termination identical across all three relays? A: Yes. All three relays feature socketable mounting with plug-in termination, ensuring mechanical and electrical compatibility in socket-based installations.

Q: What are the key differences in switching performance between these relays? A: The HC2-H-AC115V has operate and release times of 10ms each. The KHAU-11A11-120 has an operate time of 13ms and release time of 6ms. The MY2 AC110/120 (S) has operate and release times of 20ms each. Applications with timing-critical switching requirements must account for these differences.

Q: Are all three relays compliant with current environmental regulations? A: The KHAU-11A11-120 is RoHS3 compliant. The MY2 AC110/120 (S) is RoHS compliant. The original HC2-H-AC115V is obsolete and no longer subject to current compliance requirements. Both active substitutes meet current environmental standards.

Q: What is the operating temperature range difference? A: The HC2-H-AC115V operates from -50°C to 70°C. The KHAU-11A11-120 operates from -45°C to 70°C, with a 5°C reduction in minimum temperature. The MY2 AC110/120 (S) operates from -55°C to 70°C, extending the minimum temperature capability by 5°C below the original specification.
