KEMET EE2-4.5NUX-L General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The KEMET EE2-4.5NUX-L is an Active status general purpose relay with DPDT (2 Form C) contact configuration, designed for surface mount applications. This relay operates at 4.5VDC coil voltage with 2A contact rating and is suitable for switching applications up to 250VAC or 220VDC. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the EE2 series, ensuring direct functional interchangeability in circuit designs without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can EE2-4.5NU-L be used as a direct replacement for EE2-4.5NUX-L?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (coil voltage, contact form, contact rating, switching voltage, coil current, coil resistance, timing parameters) and mechanical specifications (surface mount, gull wing termination, operating temperature range). They are functionally interchangeable.

Q: Are there differences between EE2-4.5NUX-L and EE2-4.5NUH-L?

A: No electrical or mechanical differences exist between these parts. All critical parameters including coil voltage (4.5VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC/220VDC), and operating temperature range (-40°C to 85°C) are identical.

Q: Do all substitute parts have the same packaging?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly processes.

Q: What determines substitutability for this relay series?

A: Substitutability is determined by equivalence in coil voltage, contact form, contact rating, switching voltage, coil current, coil resistance, timing characteristics (operate and release times), operating temperature range, contact material composition, and compliance certifications (RoHS3, REACH status).

Q: Are there any performance differences in switching speed or contact reliability?

A: No. All substitute parts maintain identical operate time (2 ms), release time (1 ms), must operate voltage (3.38 VDC), must release voltage (0.45 VDC), and contact material composition (Silver Alloy, Gold Alloy).

Q: Can these relays be used in temperature-sensitive applications?

A: Yes. All parts are rated for the same operating temperature range of -40°C to 85°C, supporting deployment in industrial and automotive environments within this specification.
