HC3-HL-AC115V-F Equivalent & Substitute Parts

Part Overview

The HC3-HL-AC115V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a 3PDT (3 Form C) contact configuration with 115VAC coil voltage and 7A contact rating. This socketable relay includes a lighted indicator and operates across a temperature range of -50°C to 60°C. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications where this relay is specified in legacy equipment.

Substitute Part Grouping Explanation

Substitution for the HC3-HL-AC115V-F is determined by the following critical parameters: contact form (3PDT), mounting type (socketable), termination style (plug-in), coil type (non-latching), and coil voltage compatibility within the 110-120VAC range. The substitute parts identified maintain the same contact configuration and socketable design, ensuring mechanical and electrical compatibility in existing relay sockets.

Two substitute options are available:

Direct Substitute (MY3N-AC110/120): Maintains identical contact form (3PDT), socketable mounting, and plug-in termination. Coil voltage is 120VAC, which falls within the acceptable operating range for 115VAC applications. Contact rating is 5A, which is lower than the original 7A specification.

Similar Substitute (LY3N AC110/120): Maintains identical contact form (3PDT), socketable mounting, and plug-in termination. Coil voltage is 120VAC. Contact rating is 10A, which exceeds the original 7A specification and provides higher current capacity.

Engineering Selection Recommendations

MY3N-AC110/120 Selection: This Omron substitute is appropriate for applications where the original 7A contact rating can be reduced to 5A without compromising circuit performance. The MY3N-AC110/120 is RoHS compliant and active in production, ensuring long-term availability. The 120VAC coil voltage is compatible with 115VAC supply systems. Slower switching times (20ms operate/release versus 10ms) must be evaluated against application timing requirements.

LY3N AC110/120 Selection: This Omron substitute provides higher contact current capacity (10A) and is suitable for applications requiring equal or greater current handling than the original specification. The LY3N AC110/120 is RoHS compliant and active in production. The operating temperature range (-25°C to 55°C) is narrower than the original part and must be verified against system environmental requirements. Switching times are slower (25ms operate/release).

Both substitutes maintain socketable mounting and plug-in termination, ensuring compatibility with existing relay sockets designed for the HC3-HL series.

Frequently Asked Questions (FAQ)

Q: Can MY3N-AC110/120 directly replace HC3-HL-AC115V-F in all applications?

A: The MY3N-AC110/120 maintains mechanical and electrical compatibility through identical contact form (3PDT), socketable mounting, and plug-in termination. However, the contact rating is reduced from 7A to 5A. Applications must operate within the 5A maximum current limit. Switching times are also slower (20ms versus 10ms).

Q: What is the difference between the two substitute options?

A: The MY3N-AC110/120 has a 5A contact rating, while the LY3N AC110/120 has a 10A contact rating. Both maintain 3PDT configuration and socketable design. The LY3N operates at slower switching speeds (25ms) and has a narrower temperature range (-25°C to 55°C).

Q: Is the 120VAC coil voltage compatible with 115VAC systems?

A: Yes. Both substitute relays operate at 120VAC coil voltage and have must-operate voltages of 96VAC, which accommodates standard 115VAC supply systems with typical voltage variations.

Q: Are the substitute parts RoHS compliant?

A: Both MY3N-AC110/120 and LY3N AC110/120 are RoHS compliant. The original HC3-HL-AC115V-F RoHS status is not specified.

Q: What are the packaging considerations?

A: Both substitute parts are supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: How do switching times affect circuit performance?

A: The original HC3-HL-AC115V-F operates at 10ms (operate and release). MY3N-AC110/120 operates at 20ms, and LY3N AC110/120 at 25ms. Applications with timing-critical functions must evaluate whether slower switching times are acceptable.
