Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HAR22SR is determined by the following critical parameters:

• Capacitance Value: 0.22 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)
• Polarization: Polar (functional requirement)
• Operating Temperature Range: -40°C ~ 85°C (minimum coverage required)
• Automotive Compliance: AEC-Q200 certification (application requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

The substitute part UZR1HR22MCL1GB from Nichicon meets all critical substitution criteria, maintaining electrical specifications and compliance certifications while accommodating differences in lifetime rating and physical height within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

The UZR1HR22MCL1GB from Nichicon is a direct functional substitute for the EEE-1HAR22SR. Both components maintain identical electrical specifications (0.22 µF, 50 V, ±20% tolerance) and are certified to AEC-Q200 automotive standards with ROHS3 compliance. The substitute part features a reduced seated height (3.95mm versus 5.40mm), which provides improved PCB layout flexibility while maintaining identical land pattern dimensions for drop-in compatibility.

The primary distinction is the rated lifetime: the Nichicon part specifies 1000 hours at 85°C compared to the Panasonic original's 2000 hours. This difference should be evaluated against specific application duty cycles and thermal profiles. Both components are rated for the full -40°C to 85°C operating range and support identical ripple current specifications within acceptable engineering tolerances.

Frequently Asked Questions (FAQ)

Q: Can the UZR1HR22MCL1GB be used as a direct replacement for the EEE-1HAR22SR?

A: Yes. Both components share identical capacitance (0.22 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - SMD), and land pattern dimensions (4.30mm x 4.30mm). AEC-Q200 and ROHS3 certifications are maintained across both parts.

Q: What is the significance of the height difference between these parts?

A: The Nichicon substitute is 1.45mm shorter (3.95mm versus 5.40mm seated height). This reduced profile may provide design advantages in space-constrained applications while maintaining full electrical and mechanical compatibility with the original PCB footprint.

Q: How does the lifetime rating difference affect substitution suitability?

A: The Nichicon part is rated for 1000 hours at 85°C versus the Panasonic original's 2000 hours. Component selection should account for application-specific thermal stress and expected operational lifetime. Both ratings support standard automotive duty cycles.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the EEE-1HAR22SR and UZR1HR22MCL1GB carry AEC-Q200 certification, confirming suitability for automotive-grade applications with appropriate reliability and quality standards.

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

A: The UZR1HR22MCL1GB is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original EEE-1HAR22SR packaging format is not specified in the provided data.
