EE2-3NUX-L General Purpose Relay DPDT 2A 3V Equivalent & Substitute Parts

Part Overview

The EE2-3NUX-L is a general purpose relay manufactured by KEMET, configured as a DPDT (Double Pole Double Throw, 2 Form C) surface mount component with a 3VDC coil and 2A contact rating. This relay is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary to support existing designs, facilitate production continuity, and enable migration to active product alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EE2-3NUX-L is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to function as a direct substitute:

• Contact Form: DPDT (2 Form C) configuration
• Coil Voltage: 3VDC
• Contact Rating (Current): 2 A
• Switching Voltage: 250VAC, 220VDC - Max
• Coil Current: 46.7 mA
• Coil Resistance: 64.3 Ohms
• Mounting Type: Surface Mount
• Termination Style: Gull Wing
• Operating Temperature Range: -40°C ~ 85°C
• Contact Material: Silver Alloy, Gold Alloy
• Packaging: Tape & Reel (TR)
• RoHS Compliance: ROHS3 Compliant

The substitute parts EE2-3NUX-L, EE2-3NU-L, and EE2-3NUH-L are all members of the KEMET EE2 series and share identical electrical and mechanical specifications. The primary distinction is product status: EE2-3NU-L and EE2-3NUH-L are classified as Active products, while EE2-3NUX-L is Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

The EE2-3NUX-L is functionally equivalent to both EE2-3NU-L and EE2-3NUH-L across all electrical and mechanical parameters. The critical distinction is product lifecycle status:

EE2-3NUX-L is designated "Not For New Designs," indicating end-of-life classification. This part remains available in inventory (2544 Pcs) but should not be selected for new product development.

EE2-3NU-L is an Active product with equivalent specifications and lower inventory availability (2100 Pcs). This part is suitable for new designs and ongoing production.

EE2-3NUH-L is an Active product with identical specifications and the highest inventory availability (14030 Pcs). This part is the preferred selection for new designs and represents the most readily available alternative.

For existing designs currently using EE2-3NUX-L, direct substitution with either EE2-3NU-L or EE2-3NUH-L requires no circuit modifications, PCB layout changes, or firmware updates. All three parts are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance across all variants.

Frequently Asked Questions (FAQ)

Q: Can EE2-3NU-L or EE2-3NUH-L be used as direct replacements for EE2-3NUX-L in existing designs?

A: Yes. All three parts share identical electrical specifications (3VDC coil, 2A contact rating, 64.3 Ohm coil resistance, 46.7 mA coil current), mechanical configuration (DPDT, surface mount, gull wing termination), and environmental ratings (-40°C ~ 85°C operating range). No design modifications are required.

Q: What is the difference between EE2-3NU-L and EE2-3NUH-L?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: EE2-3NUH-L has significantly higher stock (14030 Pcs) compared to EE2-3NU-L (2100 Pcs). Both are Active products suitable for new designs.

Q: Why is EE2-3NUX-L marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status within KEMET's product portfolio. While existing inventory remains available, the manufacturer recommends transitioning to Active alternatives (EE2-3NU-L or EE2-3NUH-L) for long-term design support and supply chain continuity.

Q: Are there any packaging differences between these three parts?

A: No. All three parts are supplied in Tape & Reel (TR) packaging with identical moisture sensitivity level (MSL 1 - Unlimited), ensuring compatible handling and storage requirements.

Q: Do all three parts meet the same regulatory compliance standards?

A: Yes. EE2-3NUX-L, EE2-3NU-L, and EE2-3NUH-L are all ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements.

Q: What are the critical switching parameters that must match for substitution?

A: The switching voltage (250VAC, 220VDC - Max), contact form (DPDT), contact rating (2A), and contact material (Silver Alloy, Gold Alloy) must remain constant. All three parts maintain these specifications identically.

Q: Can these relays be used interchangeably on the same PCB assembly line?

A: Yes. All three parts have identical surface mount configuration, gull wing termination style, and tape & reel packaging, enabling seamless integration into existing assembly processes without tooling or fixture modifications.
