HC3-HL-AC120V-F Equivalent & Substitute Parts

Part Overview

The HC3-HL-AC120V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with 120VAC coil voltage and 7A contact rating. This socketable relay includes a lighted indicator and is designed for plug-in termination applications. The product is currently obsolete, making equivalent and substitute parts necessary for system maintenance, repair, and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC3-HL-AC120V-F is determined by the following critical parameters:

• Contact Form: Must be 3PDT (3 Form C) to maintain circuit switching capability
• Coil Voltage: Must be 120VAC to ensure proper relay actuation in existing circuits
• Mounting Type: Must be socketable to fit existing relay sockets
• Termination Style: Must be plug-in compatible with current installations
• Contact Rating: Minimum 7A required; higher ratings are acceptable for load compatibility
• Switching Voltage: Must support 250VAC maximum switching voltage

Two substitute parts meet these criteria with varying contact current ratings and product status conditions.

Engineering Selection Recommendations

MY3N-AC110/120 (Direct Substitute)

The MY3N-AC110/120 is classified as a direct substitute and is the preferred choice for new designs and ongoing production. This Omron relay maintains full compatibility with the HC3-HL-AC120V-F across all critical parameters: 3PDT contact form, 120VAC coil voltage, socketable mounting, and plug-in termination. The MY3N-AC110/120 has an active product status and carries RoHS compliance certification, ensuring long-term availability and regulatory alignment. The contact rating of 5A is lower than the original 7A specification; applications requiring the full 7A capacity must be evaluated for load compatibility. The coil current of 8.4 mA is lower than the original 10.9 mA, resulting in reduced power consumption. Operating temperature range extends to -55°C and 70°C, providing broader environmental coverage than the original part.

LY3N-AC120 (Similar Substitute)

The LY3N-AC120 is classified as a similar substitute and meets all critical substitution parameters: 3PDT contact form, 120VAC coil voltage, socketable mounting, and plug-in termination. This Omron relay carries RoHS compliance certification. The contact rating of 10A exceeds the original 7A specification, providing higher current capacity for applications with increased load requirements. The operating temperature range of -25°C to 55°C is narrower than the original specification and does not extend to the original -50°C minimum. The product status is obsolete, limiting long-term availability. Operate and release times are 25 ms compared to the original 20 ms, representing a 5 ms delay increase in switching response.

Frequently Asked Questions (FAQ)

Q: Can the MY3N-AC110/120 be used in applications requiring 7A contact current?

A: The MY3N-AC110/120 has a 5A contact rating, which is lower than the original 7A specification. Applications must be evaluated to confirm that actual load current does not exceed 5A. If the application requires sustained 7A operation, the LY3N-AC120 with 10A rating is the appropriate choice.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes maintain all critical electrical and mechanical parameters within the original specifications. Similar substitutes meet the core substitution criteria but may have variations in secondary parameters such as contact rating, timing, or temperature range. Both classifications ensure functional compatibility in the specified application.

Q: Are both substitute relays compatible with existing HC3-HL-AC120V-F relay sockets?

A: Yes. Both the MY3N-AC110/120 and LY3N-AC120 are socketable relays with plug-in termination, matching the mounting and termination requirements of the original HC3-HL-AC120V-F.

Q: What is the impact of the lower coil current in the MY3N-AC110/120?

A: The MY3N-AC110/120 draws 8.4 mA compared to the original 10.9 mA. This reduction decreases power consumption in the coil circuit and may reduce heat generation. Existing drive circuits designed for the original 10.9 mA specification will operate the MY3N-AC110/120 without issue.

Q: Does the LY3N-AC120 operate at the same speed as the original relay?

A: The LY3N-AC120 has operate and release times of 25 ms compared to the original 20 ms. This 5 ms increase in switching time may be significant in time-critical applications. The MY3N-AC110/120 maintains the original 20 ms timing.

Q: Are the substitute relays RoHS compliant?

A: Yes. Both the MY3N-AC110/120 and LY3N-AC120 carry RoHS compliance certification. The original HC3-HL-AC120V-F RoHS status is not specified in the provided data.
