LY2-DC6 Equivalent & Substitute Parts

Part Overview

The LY2-DC6 is a general purpose relay manufactured by Omron Automation and Safety, featuring a DPDT (2 Form C) contact configuration with a 6VDC coil. This socketable relay is designed for applications requiring 10A contact rating at switching voltages up to 250VAC or 125VDC. The part is currently active in production with 742 units in stock.

Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate application-specific requirements such as higher current ratings, extended temperature ranges, or alternative termination options.

Key Parameters

Substitute Part Grouping Explanation

The K10P-11D15-6 qualifies as a substitute for the LY2-DC6 based on the following critical parameters:

• Coil Voltage Match: Both relays operate on 6VDC coils
• Contact Configuration Match: Both feature DPDT (2 Form C) contact forms
• Coil Current Match: Both draw 150 mA coil current
• Coil Resistance Match: Both have 40 Ohms coil resistance
• Coil Type Match: Both are non-latching relays
• Socketable Mounting: Both support socketable mounting with plug-in termination

The K10P-11D15-6 provides enhanced specifications in contact rating (15A versus 10A) and extended operating temperature range (-45°C ~ 70°C versus -25°C ~ 55°C), making it suitable for applications requiring higher current capacity or broader temperature operation.

Parameter Comparison

Engineering Selection Recommendations

Both the LY2-DC6 and K10P-11D15-6 are active products with current manufacturing status and full compliance certifications. The LY2-DC6 maintains RoHS compliance and is REACH unaffected. The K10P-11D15-6 is ROHS3 compliant and REACH affected.

Selection between these parts depends on application requirements:

• LY2-DC6: Select when the 10A contact rating is sufficient and the -25°C ~ 55°C temperature range meets operational needs. This part supports switching voltages up to 250VAC and 125VDC.

• K10P-11D15-6: Select when higher current capacity (15A) is required or when extended temperature operation (-45°C ~ 70°C) is necessary. This part operates at reduced maximum switching voltage (120VAC). Faster switching times (13ms operate, 10ms release) may benefit time-sensitive applications.

Both parts share identical coil specifications (6VDC, 150mA, 40 Ohms) and socketable mounting, ensuring mechanical and electrical compatibility in relay socket applications.

Frequently Asked Questions (FAQ)

Q: Can the K10P-11D15-6 directly replace the LY2-DC6 in existing designs?

A: Yes, both relays share identical coil voltage (6VDC), contact configuration (DPDT), coil current (150mA), and socketable mounting. The K10P-11D15-6 provides higher current rating (15A vs 10A) and extended temperature range, making it a compatible upgrade. However, verify that the application does not require the higher switching voltage capability of the LY2-DC6 (250VAC/125VDC vs 120VAC for the substitute).

Q: What are the key differences in switching performance?

A: The K10P-11D15-6 operates faster with 13ms operate time and 10ms release time, compared to 25ms for both parameters on the LY2-DC6. The K10P-11D15-6 also has a lower must-operate voltage (4.5VDC vs 4.8VDC), providing slightly better sensitivity.

Q: Are there packaging or termination compatibility concerns?

A: Both relays use plug-in termination and socketable mounting. The K10P-11D15-6 offers additional quick-connect termination at 0.187" (4.7mm) spacing. Verify socket compatibility with your application's relay base before substitution.

Q: Which part should be selected for high-temperature applications?

A: The K10P-11D15-6 supports -45°C ~ 70°C operation, providing a 15°C higher upper temperature limit compared to the LY2-DC6 (-25°C ~ 55°C). Select the K10P-11D15-6 for applications requiring extended temperature range.

Q: Are there compliance differences between these parts?

A: The LY2-DC6 is RoHS compliant and REACH unaffected. The K10P-11D15-6 is ROHS3 compliant and REACH affected. Both meet current regulatory requirements for their respective markets.
