EE2-9NU-L Equivalent & Substitute Parts

Part Overview

The EE2-9NU-L is a general purpose relay manufactured by KEMET, configured as a DPDT (2 Form C) surface mount component with a 9VDC coil voltage and 2A contact rating. This relay is classified as obsolete, necessitating identification of active equivalent components for ongoing design support and procurement continuity. The part operates across a temperature range of -40°C to 85°C and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EE2-9NU-L is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 9VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A minimum
• Switching voltage: 250VAC, 220VDC - Max
• Coil current: 15.6 mA
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 85°C
• Coil type: Non Latching

The V23079D1006B301 manufactured by TE Connectivity Potter & Brumfield Relays satisfies all mandatory matching parameters and is classified as an active product, providing direct functional equivalence for the obsolete EE2-9NU-L.

Engineering Selection Recommendations

The V23079D1006B301 is the direct equivalent substitute for the obsolete EE2-9NU-L. Selection of this substitute is based on the following factors:

Product Status: The V23079D1006B301 maintains active product status with TE Connectivity Potter & Brumfield Relays, ensuring ongoing availability and manufacturing support. The EE2-9NU-L is obsolete and no longer manufactured by KEMET.

Compliance Certifications: Both components satisfy EAR99 export classification and maintain equivalent HTSUS tariff codes (8536.41.0020). The V23079D1006B301 is RoHS compliant, meeting current regulatory requirements for electronic components.

Electrical Equivalence: All critical electrical parameters match precisely, including coil voltage, contact form, current rating, switching voltage, and coil current specifications. Coil resistance values differ by 1 Ohm (579 Ohms versus 578 Ohms), which is within acceptable tolerance for relay coil specifications.

Packaging Consideration: The V23079D1006B301 is supplied in Tape & Reel (TR) packaging, whereas the EE2-9NU-L packaging format is not specified. Tape & Reel packaging is standard for surface mount relay applications and is compatible with automated assembly processes.

Moisture Sensitivity: The EE2-9NU-L carries MSL 1 (unlimited moisture tolerance), while the V23079D1006B301 carries MSL 3 (168 hours). This represents a more stringent moisture handling requirement for the substitute part during storage and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the V23079D1006B301 directly replace the EE2-9NU-L in existing designs?

A: Yes. The V23079D1006B301 matches all mandatory electrical and mechanical parameters of the EE2-9NU-L, including coil voltage, contact configuration, current rating, switching voltage, and operating temperature range. Both components use identical gull wing termination for surface mount assembly.

Q: What is the significance of the coil resistance difference (579 Ohms versus 578 Ohms)?

A: The 1 Ohm difference is negligible and falls within standard manufacturing tolerances for relay coil specifications. This variance does not affect circuit performance or coil current draw, which remains at 15.6 mA for both components.

Q: How does the MSL 3 rating of the V23079D1006B301 differ from the MSL 1 rating of the EE2-9NU-L?

A: MSL 3 specifies a 168-hour moisture sensitivity limit, requiring controlled storage conditions and limiting the time between component removal from packaging and assembly. MSL 1 indicates unlimited moisture tolerance. Organizations using the V23079D1006B301 must implement appropriate moisture handling procedures during component storage and assembly operations.

Q: Are there differences in contact material composition between these relays?

A: The EE2-9NU-L specifies Silver Alloy and Gold Alloy contact materials. The V23079D1006B301 specifies Silver Nickel (AgNi) and Gold (Au) contact materials. Both material compositions are suitable for the 2A contact rating and 250VAC/220VDC switching voltage specifications.

Q: What is the operational timing difference between these components?

A: The EE2-9NU-L operates in 2 ms with 1 ms release time. The V23079D1006B301 operates in 4 ms with 4 ms release time. Applications requiring faster switching response should evaluate whether the extended timing of the V23079D1006B301 is acceptable for the intended circuit function.

Q: Is the Tape & Reel packaging of the V23079D1006B301 compatible with standard assembly equipment?

A: Yes. Tape & Reel (TR) packaging is the standard format for surface mount relay components and is fully compatible with automated pick-and-place assembly equipment used in modern electronics manufacturing.
