EE2-4.5NUX Equivalent & Substitute Parts

Part Overview

The EE2-4.5NUX is a general purpose relay manufactured by KEMET, classified as a DPDT (2 Form C) surface mount component with a 4.5VDC coil voltage and 2A contact rating. This relay is designed for applications requiring double-pole, double-throw switching functionality in compact surface mount packages. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EE2-4.5NUX are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Coil voltage specification (4.5VDC), contact form configuration (DPDT / 2 Form C), contact current rating (2A), switching voltage capability (250VAC, 220VDC maximum), mounting technology (surface mount), termination style (gull wing), operating temperature range (-40°C to 85°C), coil resistance (145 Ohms), and coil current draw (31.1 mA). Additionally, substitute parts must maintain compliance with RoHS3 requirements and possess MSL rating of 1 (unlimited moisture sensitivity level).

The EE2-4.5NU is identified as a parametric equivalent substitute, sharing all critical electrical characteristics and mechanical specifications with the primary part number EE2-4.5NUX within the KEMET EE2 relay series.

Parameter Comparison

Engineering Selection Recommendations

Both the EE2-4.5NUX and EE2-4.5NU are Active status products manufactured by KEMET within the EE2 relay series. Selection between these parts is based on availability and procurement requirements rather than technical differentiation. Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory conformance for applications in restricted substance environments. The EE2-4.5NU currently maintains higher inventory availability (4087 pieces) compared to the EE2-4.5NUX (2000 pieces), which may influence procurement decisions for high-volume applications or extended lead time mitigation. All electrical parameters, mechanical specifications, and performance characteristics are identical between the two part numbers, ensuring direct functional interchangeability in circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Are EE2-4.5NUX and EE2-4.5NU electrically identical?

A: Yes. Both parts share identical coil voltage (4.5VDC), contact rating (2A), switching voltage capability (250VAC, 220VDC maximum), coil resistance (145 Ohms), coil current (31.1 mA), and all timing specifications (2ms operate time, 1ms release time). They are parametric equivalents.

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

A: Yes. Both parts are surface mount DPDT relays with gull wing termination, identical operating temperature range (-40°C to 85°C), and matching contact material composition (silver alloy, gold alloy). No circuit modifications or PCB layout changes are required.

Q: What are the key parameters that define substitution eligibility for this relay category?

A: Substitution eligibility is determined by matching coil voltage, contact form (DPDT), contact current rating (2A), switching voltage specification, mounting type (surface mount), termination style (gull wing), operating temperature range, coil resistance, and compliance certifications (RoHS3, REACH status).

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both EE2-4.5NUX and EE2-4.5NU carry MSL rating 1 (unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, classified under ECCN EAR99, and share identical HTSUS code 8536.41.0020. Regulatory status is equivalent.

Q: What is the difference between the two part numbers if all specifications are identical?

A: The part numbers differ in packaging or internal manufacturing designation within KEMET's product line, but this does not affect electrical performance, mechanical compatibility, or functional operation. Both are Active status products suitable for new designs.
