EEE-1HAR22AR Equivalent & Substitute Parts

Part Overview

The EEE-1HAR22AR is a 0.22 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications with AEC-Q200 compliance and operates across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HAR22AR is determined by the following critical parameters:

• Capacitance Value: Must be 0.22 µF
• Voltage Rating: Must be 50 V or higher
• Tolerance: ±20% or tighter
• Package Type: Radial, Can - SMD format
• Mounting Type: Surface Mount with compatible land pattern (0.169" L x 0.169" W / 4.30mm x 4.30mm)
• Polarization: Polar configuration
• Operating Temperature: Must support -40°C ~ 85°C range
• Automotive Compliance: AEC-Q200 rated
• Environmental Compliance: ROHS3 Compliant

The substitute part UZR1HR22MCL1GB from Nichicon meets all critical electrical and mechanical parameters, enabling direct functional replacement in the specified application.

Parameter Comparison

Engineering Selection Recommendations

The UZR1HR22MCL1GB from Nichicon is a qualified substitute for the obsolete EEE-1HAR22AR. Both components carry AEC-Q200 automotive certification and ROHS3 compliance, meeting regulatory requirements for automotive applications. The electrical specifications—capacitance, voltage rating, tolerance, and ripple current characteristics—are identical across both parts.

The primary distinction is the rated lifetime at 85°C: the Panasonic part specifies 2000 hours while the Nichicon substitute specifies 1000 hours. This difference should be evaluated against the specific thermal and operational profile of the target application. Both parts maintain identical physical dimensions and land pattern compatibility, ensuring direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the UZR1HR22MCL1GB replace the EEE-1HAR22AR in existing designs?

A: Yes. Both parts share identical electrical ratings (0.22 µF, 50 V, ±20%), package geometry (Radial, Can - SMD), and land pattern dimensions (0.169" L x 0.169" W). No PCB modifications are required for direct substitution.

Q: What is the significance of the different lifetime ratings?

A: The EEE-1HAR22AR is rated for 2000 hours at 85°C, while the UZR1HR22MCL1GB is rated for 1000 hours at 85°C. The selection between these parts should account for the expected operating temperature profile and mission duration of the application. Higher thermal stress or extended mission life may favor the Panasonic part if available.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the EEE-1HAR22AR and UZR1HR22MCL1GB carry AEC-Q200 certification and are rated for automotive use across the -40°C to 85°C operating temperature range.

Q: What is the packaging difference between these parts?

A: The EEE-1HAR22AR is supplied in standard packaging, while the UZR1HR22MCL1GB is supplied in Tape & Reel (TR) format. This affects procurement and assembly handling but does not impact electrical or mechanical compatibility.

Q: Are there compliance or environmental concerns with either part?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
