EEE-1HA4R7NP Equivalent & Substitute Parts

Part Overview

The EEE-1HA4R7NP is a 4.7 µF, 50 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in Surface Mount Device (SMD) packaging. This component is rated for automotive applications with AEC-Q200 compliance and features a 2000-hour lifetime at 85°C. The part is currently in active production status with 1773 units available in inventory. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same capacitance, voltage rating, and SMD package footprint.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-1HA4R7NP is determined by the following criteria:

• Capacitance value must be 4.7 µF
• Voltage rating must be 50 V or higher
• Tolerance must be ±20% or tighter
• Package must be Radial, Can - SMD with identical land size (0.260" L x 0.260" W / 6.60mm x 6.60mm)
• Mounting type must be Surface Mount
• Polarization must be Bi-Polar
• Operating temperature range must encompass -40°C ~ 85°C
• RoHS3 compliance is required

The substitute part UWP1H4R7MCL1GB from Nichicon meets all electrical and mechanical compatibility requirements for direct substitution in the same PCB footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the EEE-1HA4R7NP and UWP1H4R7MCL1GB are active production components with ROHS3 compliance and MSL 1 rating. The primary distinction between these parts is the rated lifetime at 85°C: the Panasonic part provides 2000 hours while the Nichicon substitute provides 1000 hours. Additionally, the Panasonic part carries AEC-Q200 automotive qualification, whereas the Nichicon part is rated for general purpose applications. The Nichicon substitute exhibits lower ripple current ratings at both 120 Hz and 10 kHz frequencies. Selection between these parts should be based on application-specific requirements for thermal lifetime and ripple current handling capacity.

Frequently Asked Questions (FAQ)

Q: Can the UWP1H4R7MCL1GB be used as a direct replacement for the EEE-1HA4R7NP?

A: Yes, the UWP1H4R7MCL1GB meets the core electrical and mechanical compatibility requirements. Both parts share identical capacitance (4.7 µF), voltage rating (50 V), tolerance (±20%), package footprint (0.260" x 0.260" land size), and operating temperature range (-40°C ~ 85°C). PCB layout and reflow profiles remain unchanged.

Q: What are the differences in thermal performance between these parts?

A: The EEE-1HA4R7NP is rated for 2000 hours at 85°C, while the UWP1H4R7MCL1GB is rated for 1000 hours at 85°C. Applications requiring extended thermal life at elevated temperatures should prioritize the Panasonic part.

Q: Does the height difference affect PCB assembly?

A: The seated height difference is minimal (0.213" vs 0.217", or 5.40mm vs 5.50mm). This 0.1mm variance is within standard PCB assembly tolerances and does not require design modifications.

Q: What is the significance of AEC-Q200 compliance on the Panasonic part?

A: AEC-Q200 certification indicates the Panasonic part meets automotive industry reliability standards. The Nichicon substitute is rated for general purpose applications. Selection depends on whether the application requires automotive-grade qualification.

Q: Are the ripple current ratings interchangeable?

A: No. The EEE-1HA4R7NP supports higher ripple currents (31 mA @ 120 Hz, 52.7 mA @ 10 kHz) compared to the UWP1H4R7MCL1GB (20 mA @ 120 Hz, 30 mA @ 10 kHz). Applications with high AC ripple current requirements should use the Panasonic part.
