Substitute Part Grouping Explanation

Substitution of the EEE-1HA4R7AR is determined by strict equivalence in the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 50 V (minimum; higher ratings acceptable)
Tolerance: ±20% (standard tolerance for this category)
Ripple Current: Must support 23 mA @ 120 Hz and 39.1 mA @ 10 kHz minimum
Operating Temperature: Must support -40°C ~ 85°C minimum range

Mechanical Equivalence Criteria:

Package: Radial, Can - SMD (surface mount only)
Physical Diameter: 0.197" (5.00mm) preferred; 0.157" (4.00mm) acceptable with land size verification
Height: Must not exceed 0.240" (6.10mm) for standard PCB clearance
Land Size: 0.209" L x 0.209" W (5.30mm x 5.30mm) preferred; variations acceptable if within assembly tolerances
Polarization: Polar (required)
Mounting: Surface Mount (required)

Compliance Criteria:

RoHS Status: RoHS Compliant or ROHS3 Compliant
Moisture Sensitivity: MSL 1 (Unlimited)
AEC-Q200 rating preferred for automotive applications

Substitutes are grouped into four categories based on their relationship to the main part: Direct (same electrical and mechanical specifications with improved product status), Upgrade (enhanced thermal performance or extended lifetime), Similar (minor dimensional or performance variations), and Parametric Equivalent (same core electrical parameters with acceptable mechanical variations).

Engineering Selection Recommendations

For Active Product Designs:

The Panasonic EEE-HD1H4R7R and EEE-HB1H4R7AR/EEE-HB1H4R7R series are the primary recommended substitutes. Both are Active status parts with ROHS3 compliance. The EEE-HD series offers extended thermal performance (5000 Hrs @ 105°C) and higher operating temperature range (-40°C ~ 105°C), suitable for applications requiring enhanced reliability margins. The EEE-HB series maintains the same 2000-hour lifetime at 85°C as the original part but extends the upper operating temperature to 105°C, providing thermal headroom without significant performance trade-offs. Both maintain identical electrical specifications and land size compatibility.

For Compact PCB Layouts:

The EEE-1HA4R7WAR offers a smaller physical footprint (0.157" diameter vs. 0.197") while maintaining Active product status and ROHS3 compliance. This part is suitable where PCB space constraints exist, though the reduced diameter and land size (0.169" x 0.169") must be verified against assembly equipment capabilities.

For Cross-Manufacturer Substitution:

The KEMET EDK475M050A9DAA provides electrical equivalence with Active status and ROHS3 compliance. The land size is slightly wider (0.209" x 0.256" vs. 0.209" x 0.209"), requiring verification of PCB routing and assembly compatibility. The Chemi-Con EMVA500ARA4R7MD55G offers a compact alternative with identical electrical specifications and Active status, though the smaller footprint (0.157" diameter) requires assembly process validation.

For Legacy System Support:

The EEE-1HA4R7SR and EEE-1HA4R7WR remain available in inventory with identical or similar specifications to the original part. Both carry "Not For New Designs" status but maintain RoHS compliance and are suitable for repair and maintenance of existing systems where exact form-factor matching is required.

Avoid for New Designs:

Nichicon UWJ1H4R7MCL1GB and UWX1H4R7MCL1GB are Obsolete status parts. While electrically equivalent and ROHS3 compliant, their obsolete status limits long-term availability and supply chain reliability for new product development.

Frequently Asked Questions (FAQ)

Q: Can I use EEE-HD1H4R7R as a direct replacement for EEE-1HA4R7AR?

A: Yes. The EEE-HD1H4R7R is electrically and mechanically compatible. It provides improved thermal performance (5000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and extended operating temperature range. The physical dimensions are compatible with the original PCB layout, though the height increases from 0.213" to 0.240". Verify clearance above the component before implementation.

Q: What is the difference between EEE-HB1H4R7AR and EEE-HB1H4R7R?

A: Both parts are electrically and mechanically identical. The difference is in packaging: EEE-HB1H4R7AR is supplied in Tape & Reel (TR) format, while EEE-HB1H4R7R is also supplied in Tape & Reel. Both are Active status with ROHS3 compliance and 2000 Hrs @ 105°C lifetime rating.

Q: Can I use the smaller EEE-1HA4R7WAR in place of the original part?

A: Electrical substitution is valid. The EEE-1HA4R7WAR has identical capacitance, voltage, and tolerance. However, the physical diameter is smaller (0.157" vs. 0.197") and the land size is reduced (0.169" x 0.169" vs. 0.209" x 0.209"). PCB layout and assembly equipment must be verified to accommodate the smaller footprint. The lifetime rating is lower (1000 Hrs @ 85°C vs. 2000 Hrs @ 85°C).

Q: Why is the KEMET EDK475M050A9DAA land size different?

A: The KEMET part has a wider land size (0.209" x 0.256" vs. 0.209" x 0.209"). This is a manufacturing variation between suppliers. Verify that the PCB routing and solder mask design accommodate the wider dimension. The electrical performance and physical diameter remain compatible.

Q: Are Nichicon UWJ and UWX parts still available?

A: Both Nichicon series are marked Obsolete. While current inventory exists, long-term availability is not guaranteed. For new designs or long-term product support, use Active status alternatives such as the Panasonic EEE-HB or EEE-HD series.

Q: What does "Not For New Designs" mean for the original EEE-1HA4R7AR?

A: This status indicates that Panasonic has superseded this part in their product line. While the part remains available and functional, it is not recommended for new product development. Active status alternatives (EEE-HB, EEE-HD series) should be used for designs entering production.

Q: Can I mix different manufacturers in the same assembly?

A: Yes, provided all parts meet the electrical and mechanical requirements. Verify that all substitutes are qualified for your application's environmental, thermal, and reliability requirements. Cross-manufacturer substitution may require additional qualification testing depending on your industry standards.

Q: What is the impact of using a part with higher operating temperature range?

A: Parts with extended operating temperature ranges (such as EEE-HB and EEE-HD series rated to 105°C vs. the original 85°C) provide additional thermal margin and are fully backward compatible. There is no negative impact; the higher rating simply indicates the part can operate safely at higher temperatures if required by the application.
