EEE-HA1HR33R Equivalent & Substitute Parts

Part Overview

The EEE-HA1HR33R is a 0.33 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for 1000 hours at 105°C and meets AEC-Q200 automotive standards. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the EEE-HA1HR33R is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 0.33 µF (exact match required)
• Voltage rating: 50 V (minimum acceptable)
• Tolerance: ±20% (matching tolerance band)
• Package configuration: Radial, Can - SMD (physical and electrical compatibility)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Physical dimensions: 0.157" diameter, surface mount land size 0.169" L x 0.169" W (footprint compatibility)
• Thermal rating: 1000 Hrs @ 105°C (operational lifetime equivalence)
• Operating temperature range: -40°C ~ 105°C (environmental compatibility)

The substitute part UZT1HR33MCL1GB meets all these criteria and is qualified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The UZT1HR33MCL1GB from Nichicon is a qualified direct substitute for the obsolete EEE-HA1HR33R. Both components share identical electrical specifications (capacitance, voltage rating, tolerance, and thermal lifetime) and are mechanically compatible with the same PCB footprint.

The Nichicon substitute features a reduced seated height (0.181" versus 0.213"), which provides a design advantage for space-constrained applications. Ripple current specifications are slightly lower on the substitute part, which remains acceptable for general purpose applications but may require evaluation in high-ripple-current automotive circuits where the original Panasonic part was specified.

The original EEE-HA1HR33R carried AEC-Q200 automotive qualification; the substitute part is designated for general purpose applications. For new automotive designs, component qualification status should be confirmed with the design authority.

Frequently Asked Questions (FAQ)

Q: Can the UZT1HR33MCL1GB be used as a direct replacement on existing PCBs designed for the EEE-HA1HR33R?

A: Yes. Both parts share identical capacitance (0.33 µF), voltage rating (50 V), tolerance (±20%), and surface mount land size (0.169" L x 0.169" W). The Nichicon substitute has a lower seated height (0.181" versus 0.213"), which is mechanically compatible with the original footprint.

Q: What are the key electrical differences between these two parts?

A: The electrical specifications are equivalent across capacitance, voltage rating, tolerance, operating temperature range, and thermal lifetime. Ripple current ratings differ slightly: the original Panasonic part is rated 5.1 mA @ 10 kHz, while the Nichicon substitute is rated 4.2 mA @ 10 kHz. This difference should be evaluated in applications with high AC ripple current requirements.

Q: Are there any compliance or certification differences?

A: The original EEE-HA1HR33R carries AEC-Q200 automotive qualification. The UZT1HR33MCL1GB is designated for general purpose applications. Both parts are REACH Unaffected and RoHS3 compliant (Nichicon). Automotive applications should confirm qualification requirements with the design authority.

Q: What is the difference in packaging between these parts?

A: The EEE-HA1HR33R is supplied in standard packaging, while the UZT1HR33MCL1GB is supplied in Tape & Reel (TR) format. Both are surface mount components with identical land sizes and are compatible with automated assembly equipment.
