Substitute Part Grouping Explanation

Substitution of the EEE-1HAR47AR is determined by strict equivalence across the following critical parameters:

Capacitance Value: 0.47 µF (exact match required)
Voltage Rating: 50 V (minimum acceptable rating)
Tolerance: ±20% (electrical performance tolerance)
Lifetime Rating: 2000 Hrs @ 85°C (thermal endurance specification)
Operating Temperature Range: -40°C ~ 85°C (environmental operating limits)
Package Type: Radial, Can - SMD (physical and mounting compatibility)
Physical Dimensions: 0.157" Dia (4.00mm) and height compatibility (PCB layout fit)
Surface Mount Land Size: 0.169" L × 0.169" W (4.30mm × 4.30mm) (pad pattern compatibility)
Polarization: Polar (electrical polarity requirement)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The Nichicon UZS1HR47MCL1GB meets all critical substitution criteria and is identified as a direct functional equivalent.

Engineering Selection Recommendations

The Nichicon UZS1HR47MCL1GB is a direct functional substitute for the obsolete Panasonic EEE-1HAR47AR based on electrical and mechanical parameter equivalence. Both components are ROHS3 compliant and meet the specified operating temperature and lifetime requirements.

The UZS1HR47MCL1GB offers a lower profile height (0.181" vs. 0.213"), which provides additional PCB layout flexibility without compromising electrical performance. The ripple current specification of the substitute is 4 mA at 120 Hz compared to 5 mA for the original part; this represents a conservative design margin and does not restrict substitution in applications where the original 5 mA specification was met.

Both parts carry limited product status designations (Obsolete and Not For New Designs), indicating that long-term availability may be constrained. Inventory verification is recommended prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the Nichicon UZS1HR47MCL1GB be used as a direct replacement for the Panasonic EEE-1HAR47AR?

A: Yes. Both components share identical capacitance (0.47 µF), voltage rating (50 V), tolerance (±20%), lifetime rating (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), package type (Radial, Can - SMD), and surface mount land pattern (0.169" L × 0.169" W). The substitute is physically compatible with existing PCB layouts.

Q: What is the difference in physical height between these parts?

A: The Panasonic EEE-1HAR47AR has a maximum seated height of 0.213" (5.40mm), while the Nichicon UZS1HR47MCL1GB has a maximum seated height of 0.181" (4.60mm). The Nichicon part is 0.032" (0.80mm) lower profile, which may provide additional clearance in space-constrained applications.

Q: Are there differences in ripple current specifications?

A: The Panasonic part specifies 5 mA ripple current at 120 Hz, while the Nichicon substitute specifies 4 mA at 120 Hz. The lower ripple current rating of the substitute does not restrict substitution in applications where the original 5 mA specification was satisfied.

Q: Do both parts meet automotive compliance standards?

A: The Panasonic EEE-1HAR47AR carries AEC-Q200 automotive qualification. The Nichicon UZS1HR47MCL1GB does not list AEC-Q200 certification in the provided specifications. For automotive applications requiring AEC-Q200 compliance, this difference must be evaluated against application requirements.

Q: What is the packaging difference between these parts?

A: The Panasonic EEE-1HAR47AR is supplied in standard packaging. The Nichicon UZS1HR47MCL1GB is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. Both the Panasonic EEE-1HAR47AR and Nichicon UZS1HR47MCL1GB are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited).
