EEE-1HAR33AR Equivalent & Substitute Parts

Part Overview

The EEE-1HAR33AR 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 2000 hours at 85°C and meets AEC-Q200 automotive qualification standards. The part is currently obsolete, making identification of functionally equivalent substitutes necessary for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HAR33AR 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% (as specified)
• Package Type: Radial, Can - SMD with 0.169" x 0.169" (4.30mm x 4.30mm) land size
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C minimum
• RoHS Compliance: ROHS3 Compliant

Two Nichicon aluminum electrolytic capacitors meet these substitution criteria: the UZR1HR33MCL1GB and UZS1HR33MCL1GB. Both parts match the capacitance, voltage, tolerance, package footprint, and environmental specifications of the original component. Differences in lifetime rating and product status are noted but do not preclude functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

UZS1HR33MCL1GB is the preferred substitute when lifetime performance matches the original specification requirement. This part maintains the 2000-hour rating at 85°C, identical to the EEE-1HAR33AR, and is ROHS3 compliant with MSL 1 rating. The seated height of 0.181" (4.60mm) is lower than the original 0.213" (5.40mm), providing improved PCB clearance. Both parts are obsolete, indicating limited future availability.

UZR1HR33MCL1GB is an alternative when reduced lifetime is acceptable for the application. This part provides 1000 hours at 85°C and is marked "Not For New Designs," indicating potential continued availability through existing inventory channels. The seated height of 0.156" (3.95mm) offers the most compact profile of the three options. Ripple current specifications are equivalent to the UZS1HR33MCL1GB series.

Both substitutes maintain electrical equivalence through matching capacitance, voltage rating, tolerance, and operating temperature range. PCB footprint compatibility is confirmed by identical land sizes. Selection between the two Nichicon options depends on application lifetime requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can UZR1HR33MCL1GB or UZS1HR33MCL1GB be used as direct replacements for EEE-1HAR33AR on existing PCBs?

A: Yes, both Nichicon parts are electrically and mechanically compatible. The land size is identical at 0.169" x 0.169" (4.30mm x 4.30mm). The seated heights differ slightly (UZR: 3.95mm, UZS: 4.60mm, original: 5.40mm), but all remain within typical PCB clearance tolerances for surface mount applications.

Q: What is the primary difference between UZR1HR33MCL1GB and UZS1HR33MCL1GB?

A: The primary difference is lifetime rating at 85°C. UZS1HR33MCL1GB matches the original 2000-hour specification, while UZR1HR33MCL1GB provides 1000 hours. Both maintain identical capacitance, voltage, tolerance, and operating temperature range. UZR is marked "Not For New Designs," while UZS is marked "Obsolete."

Q: Are these substitutes suitable for automotive applications?

A: The original EEE-1HAR33AR carries AEC-Q200 automotive qualification. The UZR1HR33MCL1GB also carries AEC-Q200 rating. The UZS1HR33MCL1GB does not list AEC-Q200 qualification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, UZR1HR33MCL1GB is the appropriate choice, with the understanding that its 1000-hour lifetime is half that of the original.

Q: What is the impact of the different ripple current ratings?

A: The original part specifies 3 mA at 120 Hz. Both Nichicon substitutes provide 2.8 mA at 120 Hz and 4.2 mA at 10 kHz. The slight reduction at low frequency (2.8 mA vs. 3 mA) is within typical design margins for this capacitor class and does not affect substitution eligibility.

Q: Why are all three parts marked as obsolete or "Not For New Designs"?

A: Product status reflects manufacturer discontinuation or design phase-out. Obsolete status indicates the part is no longer in active production. "Not For New Designs" indicates the manufacturer recommends against use in new designs but may maintain limited inventory. Both statuses necessitate substitute identification for ongoing production support.
