EEE-1HSR33SR Equivalent & Substitute Parts

Part Overview

The EEE-1HSR33SR 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 85°C and meets AEC-Q200 automotive specifications. The part is currently obsolete, making identification of equivalent substitutes necessary for ongoing production support and design continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HSR33SR is determined by the following core parameters:

Capacitance value: 0.33 µF (exact match required)
Voltage rating: 50 V (minimum requirement)
Tolerance: ±20% (acceptable range)
Polarization: Polar (required for electrolytic type)
Package type: Radial, Can - SMD (physical and electrical compatibility)
Mounting type: Surface Mount (assembly process compatibility)
Operating temperature range: -40°C ~ 85°C (minimum requirement)
Moisture sensitivity: MSL 1 (unlimited shelf life)

The identified substitutes meet these core electrical and mechanical parameters. Variations in physical dimensions, ripple current ratings, and lifetime specifications are secondary considerations that do not prevent functional substitution when the primary parameters align.

Engineering Selection Recommendations

Both Nichicon substitutes meet the core electrical specifications of the EEE-1HSR33SR. Selection between them depends on application requirements and product lifecycle status:

UZR1HR33MCL1GB is designated "Not For New Designs" but maintains the same 1000-hour lifetime specification as the original part. This substitute is suitable for legacy system support and field replacements where design continuity is prioritized.

UZS1HR33MCL1GB offers extended lifetime of 2000 hours at 85°C and carries ROHS3 compliance certification. This substitute is appropriate for new designs requiring enhanced reliability margins and environmental compliance. The obsolete status does not preclude its use in production applications.

Physical dimension differences exist between the original and both substitutes. The EEE-1HSR33SR has a smaller diameter (3.00mm) and greater height (5.40mm) compared to the Nichicon alternatives (4.00mm diameter). PCB layout modifications may be required to accommodate the different land sizes (3.30mm versus 4.30mm).

Frequently Asked Questions (FAQ)

Q: Can UZR1HR33MCL1GB and UZS1HR33MCL1GB be used interchangeably with EEE-1HSR33SR?

A: Both Nichicon parts meet the electrical specifications (0.33 µF, 50 V, ±20%, -40°C to 85°C, polar, surface mount). However, physical dimensions differ. PCB footprint verification is required before substitution. The Nichicon parts have larger diameters and different land sizes, necessitating layout review.

Q: What is the difference between UZR1HR33MCL1GB and UZS1HR33MCL1GB?

A: Both are 0.33 µF, 50 V Nichicon aluminum electrolytic capacitors in surface mount radial can packages. The primary difference is lifetime rating: UZR1HR33MCL1GB is rated 1000 hours at 85°C (matching the original), while UZS1HR33MCL1GB is rated 2000 hours at 85°C. UZS1HR33MCL1GB also carries ROHS3 compliance certification.

Q: Why are the physical dimensions different between the original and substitutes?

A: Different manufacturers use different case designs for equivalent capacitance and voltage ratings. The Nichicon parts use a larger diameter can (4.00mm versus 3.00mm) but are shorter in height. These dimensional differences require PCB footprint validation before implementation.

Q: Are there packaging differences between these parts?

A: The EEE-1HSR33SR packaging format is not specified in available data. Both Nichicon substitutes are supplied in Tape & Reel (TR) packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to these substitutes?

A: The original EEE-1HSR33SR carries AEC-Q200 automotive rating. UZR1HR33MCL1GB maintains AEC-Q200 compliance. UZS1HR33MCL1GB does not specify AEC-Q200 rating but carries ROHS3 compliance. For automotive applications, UZR1HR33MCL1GB is the preferred substitute.

Q: Can I use these substitutes in automotive applications?

A: UZR1HR33MCL1GB carries AEC-Q200 certification and is suitable for automotive use. UZS1HR33MCL1GB does not specify AEC-Q200 rating; verify compliance requirements with your application specifications before selection.
