RY612005 Equivalent & Substitute Parts

Part Overview

The RY612005 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays. This through-hole mounted relay features a single pole double throw (SPDT) contact configuration with an 8A contact rating and 5VDC coil voltage. The relay is designed for applications requiring non-latching operation with sealed construction and silver nickel contact material. The RY612005 maintains active product status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain component availability across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RY612005 general purpose relay are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Coil Voltage: 5VDC (determines circuit compatibility and power supply requirements)
• Contact Form: SPDT (1 Form C) (determines switching capability and circuit topology)
• Contact Rating (Current): 8 A (determines load capacity)
• Switching Voltage (Max): 400VAC (determines maximum voltage the relay can switch)
• Coil Current: 44.6 mA (determines drive circuit requirements)
• Coil Type: Non Latching (determines operational behavior)
• Mounting Type: Through Hole (determines PCB assembly compatibility)
• Termination Style: PC Pin (determines connection method)
• Seal Rating: Sealed - Fully (determines environmental protection level)
• Operating Temperature Range: -40°C ~ 70°C (determines thermal operating envelope)
• Contact Material: Silver Nickel (AgNi) (determines contact reliability and performance characteristics)
• Coil Resistance: 112 Ohms (determines electrical load characteristics)
• Must Operate Voltage: 3.5 VDC (determines minimum activation threshold)
• Must Release Voltage: 0.5 VDC (determines deactivation threshold)
• Operate Time: 9 ms (determines switching speed)
• Release Time: 5 ms (determines release speed)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.
