Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete LY2F-FD AC24 is determined by strict equivalence across the following critical parameters:

• Coil voltage specification (24VAC)
• Contact configuration (DPDT / 2 Form C)
• Current rating (10A)
• Switching voltage capability (250VAC, 125VDC maximum)
• Coil current draw (46 mA)
• Mounting type (Chassis Mount)
• Termination style (Plug In)
• Operating temperature range (-25°C ~ 55°C)
• Contact material (Silver Alloy)
• Coil resistance (180 Ohms)

The LY2F-AC24 meets all these criteria and is classified as an active product, making it a direct parametric equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The LY2F-AC24 is the direct active equivalent for the obsolete LY2F-FD AC24. Both parts are manufactured by Omron Automation and Safety and share identical electrical and mechanical specifications. The LY2F-AC24 maintains full RoHS compliance and the same MSL rating, ensuring compatibility with current supply chain and regulatory requirements. Selection of the LY2F-AC24 for replacement applications eliminates obsolescence risk while preserving all functional and performance characteristics of the original specification.
