Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HAR33SR is determined by the following mandatory parameters:

• Capacitance: 0.33 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Polarization: Polar (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in lifetime rating, ripple current specifications, and product status are noted but do not preclude functional equivalence within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both Nichicon alternatives satisfy the mandatory electrical and mechanical parameters for direct substitution of the EEE-1HAR33SR.

UZS1HR33MCL1GB is the preferred substitute, matching the original part's 2000-hour lifetime rating at 85°C and obsolete product status. This part maintains electrical performance equivalence across all specified parameters.

UZR1HR33MCL1GB is a secondary alternative with a reduced lifetime rating of 1000 hours at 85°C and "Not For New Designs" status. This part is electrically compatible but carries a shorter thermal endurance specification. Selection of this part requires confirmation that the reduced lifetime rating is acceptable for the intended application.

Both substitutes are ROHS3 compliant and carry AEC-Q200 automotive qualification (UZR1HR33MCL1GB) or equivalent compliance status, supporting use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can UZR1HR33MCL1GB be used as a direct replacement for EEE-1HAR33SR?

A: UZR1HR33MCL1GB meets all mandatory electrical and mechanical parameters. The 1000-hour lifetime at 85°C is lower than the original 2000-hour rating. Substitution is permissible if application requirements do not mandate the higher thermal endurance specification.

Q: What is the difference between UZS1HR33MCL1GB and UZR1HR33MCL1GB?

A: Both parts share identical capacitance, voltage, tolerance, package, and mounting specifications. The primary differences are lifetime rating (2000 Hrs vs. 1000 Hrs at 85°C), product status (Obsolete vs. Not For New Designs), and maximum seated height (4.60mm vs. 3.95mm). UZS1HR33MCL1GB provides longer thermal endurance.

Q: Are there height clearance considerations when substituting these parts?

A: Yes. The original EEE-1HAR33SR has a maximum seated height of 5.40mm. UZR1HR33MCL1GB measures 3.95mm and UZS1HR33MCL1GB measures 4.60mm. Both alternatives are shorter and will fit within the original footprint. Verify PCB layout clearance if height-constrained applications are present.

Q: Do all three parts use the same PCB land pattern?

A: Yes. All three parts specify identical surface mount land size of 0.169" L x 0.169" W (4.30mm x 4.30mm), enabling direct PCB layout compatibility without redesign.

Q: Are these parts suitable for automotive applications?

A: EEE-1HAR33SR and UZR1HR33MCL1GB carry AEC-Q200 automotive qualification. UZS1HR33MCL1GB does not list AEC-Q200 rating but is ROHS3 compliant. Confirm automotive qualification requirements with application specifications before final selection.
