EC2-12NJ General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The EC2-12NJ is a general purpose relay manufactured by KEMET, classified as a DPDT (Double Pole Double Throw, 2 Form C) relay with a 12VDC coil voltage and 2A contact rating. This through-hole mounted relay is designed for general switching applications requiring non-latching operation across industrial and commercial environments. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to address packaging variations, inventory availability, or specific application requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EC2-12NJ are identified based on strict electrical and mechanical parameter equivalence within the EC2 series. The substitution logic is based on the following critical parameters that must remain identical:

• Contact Form: DPDT (2 Form C)
• Coil Voltage: 12VDC
• Contact Rating (Current): 2 A
• Switching Voltage: 250VAC, 220VDC - Max
• Coil Current: 11.7 mA
• Coil Type: Non Latching
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -40°C ~ 85°C
• Contact Material: Silver Alloy, Gold Alloy
• Coil Resistance: 1.03 kOhms
• Must Operate Voltage: 9 VDC
• Must Release Voltage: 1.2 VDC
• Operate Time: 2 ms
• Release Time: 1 ms

The EC2-12NU is classified as a parametric equivalent within the EC2 series. Variations between the main part and substitute are limited to packaging configuration only, with no electrical or mechanical performance differences.

Parameter Comparison

Engineering Selection Recommendations

Both the EC2-12NJ and EC2-12NU are Active product status components manufactured by KEMET with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined by packaging requirements and inventory availability rather than electrical or mechanical performance differences.

The EC2-12NJ is supplied in standard packaging configuration, while the EC2-12NU is supplied in tube packaging. Both parts are suitable for through-hole PCB assembly applications requiring DPDT relay functionality with 12VDC coil voltage and 2A contact rating.

For applications requiring specific packaging formats for automated assembly processes, the tube-packaged EC2-12NU may be preferred. For applications with flexible packaging requirements, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can EC2-12NU be used as a direct replacement for EC2-12NJ?

A: Yes. The EC2-12NU is a parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging format (tube versus standard). Both parts are functionally interchangeable in circuit applications.

Q: What is the difference between EC2-12NJ and EC2-12NU?

A: The parts are electrically and mechanically identical. The EC2-12NJ uses standard packaging while the EC2-12NU uses tube packaging. This distinction affects handling, storage, and automated assembly compatibility only.

Q: Are both parts RoHS compliant?

A: Yes. Both EC2-12NJ and EC2-12NU are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the coil voltage requirement for these relays?

A: Both parts require 12VDC coil voltage. The must-operate voltage is 9VDC minimum and must-release voltage is 1.2VDC maximum.

Q: What contact rating do these relays support?

A: Both parts support 2A contact rating with maximum switching voltage of 250VAC or 220VDC.

Q: Are these relays suitable for high-temperature applications?

A: Both parts operate across the temperature range of -40°C to 85°C, suitable for industrial and commercial environments within this specification.

Q: What is the through-hole termination style?

A: Both parts use PC Pin termination style for direct PCB mounting through standard plated through-holes.

Q: What is the switching speed of these relays?
