EE2-3NUX General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The EE2-3NUX is a general purpose relay manufactured by KEMET, classified as a DPDT (2 Form C) surface mount component with a 3VDC coil voltage and 2A contact rating. This relay is designed for switching applications requiring dual-pole, dual-throw functionality in compact surface mount packages. The part maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory optimization, or supply chain continuity while maintaining identical functional performance.

Substitute Part Grouping Explanation

Substitute parts for the EE2-3NUX are identified based on strict parametric equivalence within the KEMET EE2 series. All substitute parts maintain identical electrical and mechanical specifications across the following critical parameters: DPDT contact form, 3VDC coil voltage, 2A contact rating, 250VAC/220VDC maximum switching voltage, 64.3 Ohm coil resistance, 46.7 mA coil current, surface mount gull wing termination, -40°C to 85°C operating temperature range, and silver/gold alloy contact materials. All substitute parts retain Active product status, ROHS3 compliance, and REACH unaffected classification. Substitution is valid when these parameters are held constant across part selection.

Parameter Comparison

Engineering Selection Recommendations

All three parts—EE2-3NUX, EE2-3NU, and EE2-3NUH—are functionally equivalent and interchangeable for applications requiring a 3VDC DPDT general purpose relay with 2A contact rating and surface mount gull wing termination. Selection between these parts is based on availability and inventory status rather than electrical or mechanical differentiation. All parts maintain Active product status, ensuring continued manufacturer support and supply chain viability. ROHS3 compliance and REACH unaffected classification are uniform across all three options, satisfying regulatory requirements for industrial and commercial applications. The EE2-3NUH variant currently maintains the highest inventory level at 4378 pieces, followed by EE2-3NU at 2100 pieces, and EE2-3NUX at 826 pieces. Component selection should prioritize availability while maintaining design consistency within the EE2 series.
