EEE-1ES4R7SR Equivalent & Substitute Parts

Part Overview

The Panasonic EEE-1ES4R7SR is a 4.7 µF, 25 V aluminum electrolytic capacitor in surface mount radial can package, rated for 1000 hours at 85°C with AEC-Q200 automotive qualification. This part is obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical performance within the specified capacitance, voltage, and ripple current parameters while accommodating mechanical and packaging variations.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Surface Mount (exact match required)
Package / Case: Radial, Can - SMD (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Lifetime @ 85°C: 1000 Hrs minimum (equal or greater acceptable)
Ripple Current Ratings: Must meet or exceed specified values at both 120 Hz and 10 kHz

Substitute parts may vary in physical dimensions (diameter and height), land size, ESR characteristics, and product status. Parts with extended lifetime ratings (2000 Hrs @ 85°C) are acceptable as they provide enhanced reliability margins.

Engineering Selection Recommendations

Primary Substitutes (Panasonic EEE-1EA Series)

EEE-1EA4R7SR and EEE-1EA4R7AR are direct electrical equivalents with extended 2000-hour lifetime ratings. Both parts are RoHS Compliant and maintain the same capacitance, voltage, and tolerance specifications. The primary consideration is physical footprint: these parts feature a larger 0.157" (4.00mm) diameter compared to the original 0.118" (3.00mm), requiring PCB layout verification. EEE-1EA4R7SR offers higher inventory availability (20,848 pcs) in Cut Tape & Digi-Reel packaging.

Secondary Substitutes (Nichicon UWX/UWJ Series)

UWX1E4R7MCL1GB and UWJ1E4R7MCL1GB provide equivalent electrical performance with 2000-hour lifetime ratings and ROHS3 compliance. These parts share the 0.157" (4.00mm) diameter footprint with Panasonic EEE-1EA variants. UWX1E4R7MCL1GB offers superior inventory (16,100 pcs) and maintains the original 0.213" (5.40mm) height. REACH status differs: UWJ1E4R7MCL1GB is REACH Affected, while UWX1E4R7MCL1GB is REACH Unaffected.

Automotive-Qualified Alternative (Nichicon UZR Series)

UZR1E4R7MCL1GB maintains the original 1000-hour lifetime rating with AEC-Q200 automotive qualification matching the main part. This part features a compact 0.156" (3.95mm) height and 0.157" (4.00mm) diameter. Ripple current ratings (16 mA @ 120 Hz, 24 mA @ 10 kHz) exceed the original specification. Inventory is limited (928 pcs).

Cross-Manufacturer Option (Cornell Dubilier AVE475M25B12T-F)

AVE475M25B12T-F provides 2000-hour lifetime with ROHS3 compliance and equivalent electrical specifications. This part exhibits significantly higher ripple current capability at 10 kHz (505.4 mA versus 20.4 mA), making it suitable for high-frequency applications. Physical dimensions are comparable to Panasonic EEE-1EA series. Product status is Obsolete.

Footprint Considerations

The original EEE-1ES4R7SR uses a 3.00mm diameter can with 3.30mm x 3.30mm land size. All substitute parts except UZR1E4R7MCL1GB use a larger 4.00mm diameter can with 4.30mm x 4.30mm land size. PCB layout modification is required for these substitutions. UZR1E4R7MCL1GB maintains the 4.00mm diameter but offers the most compact height (3.95mm).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a larger physical diameter on my existing PCB?

A: No. The original EEE-1ES4R7SR uses a 3.00mm diameter can, while most substitutes use 4.00mm diameter. This requires PCB layout modification and pad repositioning. Only UZR1E4R7MCL1GB maintains compatibility with the original 4.00mm diameter footprint if your PCB was designed for that size. Verify your PCB design specifications before selecting a substitute.

Q: What is the difference between EEE-1EA4R7SR and EEE-1EA4R7AR?

A: Both parts are electrically identical with 4.7 µF, 25 V, ±20% specifications and 2000-hour lifetime ratings. The primary difference is packaging: EEE-1EA4R7SR is supplied in Cut Tape & Digi-Reel format with 20,848 pcs inventory, while EEE-1EA4R7AR is supplied in Tape & Reel format with 3,191 pcs inventory. Select based on your procurement and assembly requirements.

Q: Why do some substitutes have higher ripple current ratings?

A: Ripple current capacity depends on internal construction and thermal design. Parts with higher ripple current ratings (such as AVE475M25B12T-F at 505.4 mA @ 10 kHz) provide additional margin for high-frequency switching applications. The original EEE-1ES4R7SR specifies 20.4 mA @ 10 kHz; all listed substitutes meet or exceed this requirement.

Q: Is the Nichicon UZR1E4R7MCL1GB suitable for automotive applications?

A: Yes. UZR1E4R7MCL1GB carries AEC-Q200 automotive qualification matching the original part. It maintains the 1000-hour lifetime rating at 85°C and operates across the -40°C to 85°C temperature range. This part is the preferred choice for automotive applications requiring direct functional equivalence.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" are available for purchase but are not recommended for new product development. Panasonic EEE-1EA series parts carry this status, indicating they may be phased out. However, they remain suitable for legacy product support and maintenance. For new designs, consider UZR1E4R7MCL1GB (automotive-qualified) or UWX1E4R7MCL1GB (general purpose).

Q: Are all substitutes RoHS compliant?

A: Panasonic EEE-1ES4R7SR does not specify RoHS status. Panasonic EEE-1EA series parts are RoHS Compliant. Nichicon UWX1E4R7MCL1GB, UWJ1E4R7MCL1GB, and UZR1E4R7MCL1GB are ROHS3 Compliant. Cornell Dubilier AVE475M25B12T-F is ROHS3 Compliant. Verify RoHS requirements for your application before final selection.

Q: What is the difference between REACH Unaffected and REACH Affected status?

A: REACH Unaffected parts contain no substances of concern under EU REACH regulations and require no additional documentation. REACH Affected parts (such as UWJ1E4R7MCL1GB) may contain regulated substances and require compliance documentation for EU distribution. Select REACH Unaffected parts for simplified supply chain management in regulated markets.
