Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEE-1HSR22SR is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 0.22 µF (exact match required)
• Voltage rating: 50 V (minimum acceptable)
• Tolerance: ±20% (matching specification)
• Lifetime rating: 1000 Hrs @ 85°C (minimum acceptable)
• Operating temperature range: -40°C ~ 85°C (minimum acceptable)
• Polarization: Polar (exact match required)
• Mounting type: Surface Mount (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Automotive compliance: AEC-Q200 (required for automotive applications)

The UZR1HR22MCL1GB from Nichicon meets all electrical equivalence criteria. Mechanical dimensions differ slightly due to manufacturer design variations, but both components utilize compatible surface mount land patterns within acceptable tolerances for standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The UZR1HR22MCL1GB from Nichicon is electrically and functionally equivalent to the EEE-1HSR22SR for applications requiring a 0.22 µF, 50 V aluminum electrolytic capacitor with automotive-grade AEC-Q200 compliance. Both components satisfy identical electrical specifications and thermal performance requirements.

The Nichicon substitute carries a "Not For New Designs" status, indicating limited long-term availability. For new design implementations, consultation with component suppliers is recommended to identify actively manufactured alternatives meeting the same electrical and compliance parameters.

Physical dimensions differ between the two components. PCB layout modifications may be necessary to accommodate the larger case diameter and different land pattern of the Nichicon part. Standard surface mount assembly processes remain compatible with both components.

Frequently Asked Questions (FAQ)

Q: Can the UZR1HR22MCL1GB directly replace the EEE-1HSR22SR without PCB modifications?

A: Electrical substitution is direct. Physical substitution requires PCB layout verification. The Nichicon part has a larger case diameter (4.00 mm vs. 3.00 mm) and different land pattern dimensions (4.30 × 4.30 mm vs. 3.30 × 3.30 mm). Existing PCB footprints designed for the Panasonic component may require adjustment.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the EEE-1HSR22SR and UZR1HR22MCL1GB carry AEC-Q200 automotive qualification and operate across the -40°C to 85°C temperature range required for automotive environments.

Q: What is the significance of the "Obsolete" and "Not For New Designs" product statuses?

A: The EEE-1HSR22SR is obsolete and no longer manufactured. The UZR1HR22MCL1GB is in limited production with restricted availability for new applications. Both statuses indicate supply constraints. For designs requiring long-term component availability, alternative suppliers should be evaluated.

Q: Do the ripple current specifications differ between these parts?

A: Ripple current at 120 Hz is identical (2 mA). At 10 kHz, the Panasonic part specifies 3.4 mA while the Nichicon part specifies 3 mA. Both values are within acceptable operating margins for standard circuit applications.

Q: What packaging formats are available for these components?

A: The EEE-1HSR22SR is supplied in standard packaging. The UZR1HR22MCL1GB is available in Tape & Reel (TR) format, suitable for automated assembly processes.
