EB2-5NU-L General Purpose Relay DPDT 1A 5V Equivalent & Substitute Parts

Part Overview

The EB2-5NU-L is a general purpose relay manufactured by KEMET, classified as a Double Pole Double Throw (DPDT) surface mount component with a 5VDC coil voltage and 1A contact rating. This relay is designed for general switching applications requiring dual independent circuits with maximum switching capability of 250VAC or 220VDC. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary EB2-5NU-L is unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats are required for specific manufacturing processes. All substitute parts listed maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability within the same circuit design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2-5NU-L is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish direct interchangeability:

Electrical Equivalence Requirements:

• Coil voltage: 5VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 1 A
• Switching voltage: 250VAC, 220VDC maximum
• Coil current: 28 mA
• Coil resistance: 178 Ohms
• Must operate voltage: 3.75 VDC
• Must release voltage: 0.5 VDC
• Operate time: 2 ms
• Release time: 1 ms
• Operating temperature range: -40°C ~ 85°C

Mechanical Equivalence Requirements:

• Mounting type: Surface Mount
• Termination style: Gull Wing
• Contact material: Silver Alloy, Gold Alloy

Compliance Equivalence Requirements:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

All substitute parts listed below meet these criteria. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and are selected based on manufacturing process requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by KEMET and maintain active production status. Selection between the EB2-5NU-L and its substitutes is based on availability and packaging requirements rather than electrical performance differences.

Tape & Reel (TR) Packaging Options:

• EB2-5NU-L: Primary part, 7700 units in stock
• UB2-5NU-L: UB2 series equivalent, 2318 units in stock
• UD2-5NU-L: UD2 series equivalent, 2500 units in stock

Cut Tape (CT) Packaging Options:

• UB2-5NUN-L: UB2 series equivalent, 5900 units in stock
• UD2-5NUN-L: UD2 series equivalent, 2971 units in stock

All parts carry ROHS3 compliance certification and REACH unaffected status, confirming regulatory alignment for applications subject to environmental and hazardous substance restrictions. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related component degradation concerns.

Series designation (EB2, UB2, UD2) reflects internal KEMET product line organization and does not affect functional interchangeability. Component selection should prioritize inventory availability and packaging format compatibility with existing manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can EB2-5NU-L be directly replaced with UB2-5NU-L or UD2-5NU-L without circuit modification?

A: Yes. All substitute parts maintain identical electrical specifications including coil voltage, contact rating, switching voltage, timing characteristics, and operating temperature range. Direct substitution requires no circuit design changes.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Packaging format affects manufacturing process compatibility only. Tape & Reel packaging is used for automated pick-and-place assembly systems, while Cut Tape packaging is used for manual assembly or alternative handling processes. Electrical and mechanical performance are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. EB2-5NU-L, UB2-5NU-L, UB2-5NUN-L, UD2-5NU-L, and UD2-5NUN-L all carry ROHS3 compliance certification and REACH unaffected status.

Q: What does MSL 1 rating mean for component storage?

A: MSL 1 indicates unlimited shelf life under standard storage conditions. No moisture bake-out procedures are required prior to assembly, and the component does not degrade due to moisture absorption during storage.

Q: Can I use Cut Tape (CT) packaging in place of Tape & Reel (TR) packaging?

A: Substitution between packaging formats depends on manufacturing equipment compatibility. Cut Tape packaging is not compatible with automated tape-fed assembly systems designed for Tape & Reel format. Verify equipment specifications before substituting packaging types.

Q: Do all substitute parts have the same coil resistance?

A: Yes. All substitute parts maintain 178 Ohms coil resistance, ensuring identical power consumption and drive circuit requirements.

Q: What is the maximum switching voltage for these relays?

A: All parts support maximum switching voltage of 250VAC or 220VDC, with contact rating of 1A. Load calculations must account for both voltage and current limits.

Q: Are there any differences in contact material between substitute parts?

A: No. All parts use identical contact material composition: Silver Alloy and Gold Alloy. Contact material consistency ensures equivalent switching performance and contact reliability across all substitutes.
