KEMET EE2-5ND General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The KEMET EE2-5ND is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 2A switching capacity at 5VDC coil voltage. This surface mount component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement continuity. The EE2-5ND remains available in limited inventory (644 pieces), but active alternatives ensure long-term supply chain reliability and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KEMET EE2-5ND is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Coil voltage: 5VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 2 A minimum (exact match required)
• Switching voltage: 250VAC, 220VDC - Max (exact match required)
• Must operate voltage: 3.75 VDC (exact match required)
• Must release voltage: 0.5 VDC (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount (exact match required)
• Termination style: Gull Wing (exact match required)
• Contact material: Silver Alloy, Gold Alloy (exact match required)

Compliance Requirements:

• RoHS3 Compliant (exact match required)
• REACH Unaffected (exact match required)

The EE2-5NU qualifies as a direct substitute based on full alignment with all critical electrical, mechanical, and compliance parameters. Variations in coil current (28 mA vs. 40 mA) and coil resistance (178 Ohms vs. 125 Ohms) do not affect substitution eligibility, as these parameters remain within acceptable operational ranges for the specified application class.

Parameter Comparison

Engineering Selection Recommendations

The KEMET EE2-5NU is the direct substitute for the obsolete EE2-5ND. Both components are manufactured by KEMET within the EE2 series and maintain identical electrical and mechanical specifications across all critical parameters. The EE2-5NU holds active product status, ensuring ongoing availability and supply chain continuity.

Selection of the EE2-5NU is supported by:

Product Status: The EE2-5NU is classified as active, providing long-term procurement reliability compared to the obsolete EE2-5ND.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.

Electrical Equivalence: Identical coil voltage (5VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC, 220VDC - Max), and timing specifications (2 ms operate, 1 ms release) ensure functional interchangeability.

Mechanical Compatibility: Matching surface mount configuration with gull wing termination enables direct PCB layout compatibility without redesign.

Operational Parameters: Identical must-operate voltage (3.75 VDC), must-release voltage (0.5 VDC), and operating temperature range (-40°C ~ 85°C) confirm circuit-level compatibility.

The reduction in coil current from 40 mA to 28 mA in the EE2-5NU represents an efficiency improvement that does not compromise performance within the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can the EE2-5NU directly replace the EE2-5ND without PCB modifications?

A: Yes. Both components feature identical surface mount configuration with gull wing termination, enabling direct PCB layout compatibility. No redesign is required.

Q: What is the significance of the coil current difference (40 mA vs. 28 mA)?

A: The EE2-5NU operates at lower coil current while maintaining identical electrical performance across all critical parameters. This represents an efficiency improvement and does not affect circuit compatibility or relay function.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the EE2-5ND and EE2-5NU are ROHS3 compliant and REACH unaffected, meeting current manufacturing and environmental regulations.

Q: Why is the EE2-5ND classified as obsolete?

A: Product obsolescence reflects KEMET's product lifecycle management. The EE2-5NU serves as the active equivalent, ensuring continued availability of this relay specification.

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. The EE2-5NU is supplied in tube packaging, while the EE2-5ND packaging format is not specified. Packaging format does not affect component performance or PCB integration.

Q: What are the critical parameters for confirming substitution eligibility?

A: Substitution is confirmed by matching coil voltage (5VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC, 220VDC - Max), mounting type (surface mount), termination style (gull wing), and operating temperature range (-40°C ~ 85°C).

Q: Is the EE2-5NU suitable for new design implementations?

A: Yes. The EE2-5NU is classified as active and is the recommended component for new designs requiring a 5VDC DPDT general purpose relay with 2A contact rating and surface mount configuration.
