Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HAR33NR is determined by the following critical parameters:

• Capacitance Value: 0.33 µF (exact match required)
• Voltage Rating: 50 V (minimum; higher ratings acceptable)
• Tolerance: ±20% (matching tolerance band)
• Package Type: Radial, Can - SMD (physical and electrical compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Physical Dimensions: Diameter 0.157" (4.00 mm), Height ≤ 0.213" (5.40 mm), Land size 0.169" x 0.169" (4.30 mm x 4.30 mm)
• Operating Temperature Range: -40°C to 85°C minimum
• Polarization: Bi-Polar
• Compliance: RoHS3 and REACH requirements

The UWP1HR33MCL1GB meets all critical substitution parameters and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The UWP1HR33MCL1GB from Nichicon is a direct substitute for the obsolete EEE-1HAR33NR. Both components share identical electrical specifications (0.33 µF, 50 V, ±20% tolerance), physical package dimensions, and compliance certifications (RoHS3, REACH Unaffected). The Nichicon part is currently in active production status with confirmed inventory availability.

The primary difference is the rated lifetime at 85°C: the original Panasonic part specifies 2000 hours while the Nichicon substitute specifies 1000 hours. This difference should be evaluated against application requirements. The Nichicon part also exhibits slightly lower ripple current ratings (2.8 mA @ 120 Hz and 4.2 mA @ 10 kHz compared to 3 mA and 5.1 mA respectively), which may be relevant in high-ripple current applications.

Both components are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the UWP1HR33MCL1GB replace the EEE-1HAR33NR in automotive applications?

A: The UWP1HR33MCL1GB meets the electrical and physical requirements for direct substitution. However, the original EEE-1HAR33NR carries AEC-Q200 automotive qualification while the Nichicon part does not list this certification. Application-specific automotive qualification requirements should be confirmed before deployment.

Q: What is the impact of the different lifetime ratings (2000 Hrs vs. 1000 Hrs @ 85°C)?

A: The lifetime rating indicates expected operational duration under specified thermal stress. Applications requiring extended service life at elevated temperatures should account for the reduced lifetime specification of the substitute part.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. Both parts share identical diameter (0.157" / 4.00 mm), land size (0.169" x 0.169" / 4.30 mm x 4.30 mm), and mounting type (Surface Mount). The height difference of 0.004" (0.10 mm) is within typical PCB clearance tolerances.

Q: What packaging formats are available for the substitute part?

A: The UWP1HR33MCL1GB is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the EEE-1HAR33NR and UWP1HR33MCL1GB are RoHS3 compliant and REACH Unaffected, meeting current environmental standards for electronic components.
