LY2-AC6 Equivalent & Substitute Parts

Part Overview

The Omron LY2-AC6 is a general purpose relay with DPDT (2 Form C) contact configuration rated for 10A at 6VAC coil voltage. This socketable relay is designed for applications requiring reliable switching of AC and DC loads. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

The K10P-11A15-6 from TE Connectivity Potter & Brumfield Relays qualifies as a substitute for the LY2-AC6 based on the following critical parameters:

• Coil voltage matches at 6VAC
• Contact form is identical: DPDT (2 Form C)
• Mounting type is socketable with plug-in termination
• Coil type is non-latching
• Relay type is general purpose
• Contact material is silver-based (Silver Cadmium Oxide)

The K10P-11A15-6 has a higher current rating (15A versus 10A), which provides additional capacity for the same coil voltage and contact configuration. This uprating is acceptable for applications originally designed for the 10A LY2-AC6.

Parameter Comparison

Engineering Selection Recommendations

The K10P-11A15-6 is an active product from a major relay manufacturer, ensuring long-term availability for replacement applications. The substitute part maintains functional equivalence through matching coil voltage, contact configuration, and socketable mounting.

The K10P-11A15-6 offers improved performance characteristics including faster switching times (13ms operate, 10ms release versus 25ms for both), wider operating temperature range (-45°C to 70°C), and higher current capacity (15A). These enhancements make it suitable for direct substitution in legacy equipment.

RoHS compliance status differs between the parts. The original LY2-AC6 is RoHS compliant, while the K10P-11A15-6 is RoHS non-compliant. Applications subject to RoHS requirements must account for this difference in material composition and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can the K10P-11A15-6 directly replace the LY2-AC6 in existing equipment?

A: Yes. Both relays share identical coil voltage (6VAC), contact form (DPDT), mounting type (socketable), and termination style (plug-in). The higher current rating of the K10P-11A15-6 (15A) is compatible with applications designed for 10A operation.

Q: What are the key differences between these two relays?

A: The K10P-11A15-6 has a higher current rating (15A vs 10A), faster switching times (13ms/10ms vs 25ms/25ms), wider operating temperature range (-45°C to 70°C vs -25°C to 55°C), and different contact material (Silver Cadmium Oxide vs Silver Alloy). The K10P-11A15-6 is RoHS non-compliant while the LY2-AC6 is RoHS compliant.

Q: Are there packaging differences between these relays?

A: The LY2-AC6 uses standard packaging, while the K10P-11A15-6 is supplied in trays. Both are socketable with plug-in termination, ensuring mechanical compatibility in standard relay sockets.

Q: What is the coil current difference and does it matter?

A: The LY2-AC6 draws 183 mA while the K10P-11A15-6 draws 200 mA. This 17 mA difference is minimal and should not impact most control circuit designs. Verify that the coil supply circuit can accommodate the slightly higher current draw.

Q: How do the switching voltage ratings compare?

A: The LY2-AC6 is rated for 250VAC and 125VDC maximum switching voltage. The K10P-11A15-6 is rated for 120VAC maximum. Applications requiring switching of higher DC voltages should account for this reduced rating on the substitute part.
