KEMET EE2-3NUH General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The KEMET EE2-3NUH is an active general purpose relay with DPDT (2 Form C) contact configuration, designed for surface mount applications. This relay operates at 3VDC coil voltage with a 2A contact rating and supports switching voltages up to 250VAC or 220VDC maximum. The component is ROHS3 compliant and maintains an unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and commercial applications requiring reliable switching performance across extended temperature ranges from -40°C to 85°C.

Identifying equivalent and substitute parts is necessary when managing component availability, optimizing inventory levels, or addressing supply chain constraints while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KEMET EE2-3NUH relay are identified based on strict electrical and mechanical parameter matching within the EE2 series. The substitution logic is based on the following critical parameters that must remain identical:

Electrical Parameters:

• Coil voltage: 3VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A
• Switching voltage: 250VAC, 220VDC maximum
• Coil current: 46.7 mA
• Coil resistance: 64.3 Ohms
• Must operate voltage: 2.25 VDC
• Must release voltage: 0.3 VDC
• Operate time: 2 ms
• Release time: 1 ms

Mechanical Parameters:

• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 85°C
• Contact material: Silver Alloy, Gold Alloy

Compliance Parameters:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

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

Parameter Comparison

Engineering Selection Recommendations

The KEMET EE2-3NU is a direct parametric equivalent to the EE2-3NUH. Both components are manufactured by KEMET within the same EE2 series and share identical electrical specifications, mechanical characteristics, and compliance certifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

Both parts maintain active product status and full ROHS3 compliance with REACH unaffected designation, ensuring regulatory compliance for industrial and commercial applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, supporting long-term inventory management.

Frequently Asked Questions (FAQ)

Q: Can EE2-3NU be used as a direct replacement for EE2-3NUH?

A: Yes. The EE2-3NU is a parametric equivalent with identical electrical and mechanical specifications, including coil voltage, contact configuration, current rating, switching voltage, timing characteristics, and operating temperature range. Both components are ROHS3 compliant with MSL 1 rating.

Q: Are there any differences in packaging or termination between these parts?

A: No. Both parts use identical gull wing termination style and surface mount packaging in tube format. Physical footprint and PCB assembly compatibility are identical.

Q: What determines whether a relay can substitute for the EE2-3NUH?

A: Substitution requires matching all critical parameters: 3VDC coil voltage, DPDT contact form, 2A contact rating, 250VAC/220VDC switching voltage, 46.7mA coil current, 64.3 Ohms coil resistance, 2ms operate time, 1ms release time, gull wing termination, surface mount configuration, and -40°C to 85°C operating temperature range. Compliance certifications (ROHS3, MSL 1, REACH unaffected) must also align.

Q: Is there a performance difference between these equivalent parts?

A: No. Both parts are manufactured to identical specifications by KEMET and deliver equivalent electrical performance, switching characteristics, and reliability within the specified operating parameters.

Q: How should I select between EE2-3NUH and EE2-3NU?

A: Selection is based on component availability and inventory status. Both parts are functionally and mechanically interchangeable. Current inventory levels are 4378 pcs for EE2-3NUH and 2100 pcs for EE2-3NU.
