KEMET EC2-3NJ General Purpose Relay DPDT 2A 3V - Equivalent & Substitute Parts

Part Overview

The KEMET EC2-3NJ is a general purpose relay with DPDT (Double Pole Double Throw) contact configuration, rated for 2A switching current at 3VDC coil voltage. This through-hole mounted relay is designed for applications requiring non-latching relay operation with silver alloy and gold alloy contacts. The part is currently active in production with 2200 units in stock.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and operational characteristics are maintained within the specified parameter ranges. Alternative models may be required due to packaging availability, supply chain considerations, or specific application mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

The EC2-3NU is a direct electrical and mechanical equivalent to the EC2-3NJ. Both parts are manufactured by KEMET within the active EC2 series and maintain identical specifications across all critical electrical parameters, contact ratings, timing characteristics, and environmental operating ranges.

Both parts are REACH Unaffected and classified under ECCN EAR99, with identical HTSUS coding (8536.41.0020), indicating equivalent regulatory and trade compliance status.

The primary distinction between these parts is packaging configuration. The EC2-3NJ is supplied in standard packaging, while the EC2-3NU is supplied in tube packaging. This difference does not affect electrical performance, mechanical compatibility, or functional operation in circuit applications.

Selection between EC2-3NJ and EC2-3NU should be based on packaging requirements and supply chain availability. Both parts are suitable for direct substitution in applications requiring a 3VDC DPDT general purpose relay with 2A contact rating and through-hole PC pin termination.

Frequently Asked Questions (FAQ)
