Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by strict equivalence in the following parameters:

Capacitance Value: Must be 4700 µF (no tolerance variation)
Voltage Rating: Must be 10 V or higher (higher voltage ratings are acceptable as they provide backward compatibility)
Polarization: Must remain Polar
Package Configuration: Must be Radial, Can with Through Hole mounting
Lead Spacing: Must be 0.197" (5.00 mm)
Physical Dimensions: Diameter and height must accommodate the PCB footprint

Secondary parameters that may vary between substitutes include operating temperature range, lifetime at temperature, ripple current capacity, and product status. These variations do not prevent substitution but indicate performance differences under specific operating conditions.

Engineering Selection Recommendations

Direct Substitutes (Active Status, Recommended for New Designs)

860020278025 (Würth Elektronik WCAP-ATG5) provides direct substitution with improved thermal performance. Operating temperature extends to 105°C with 2000-hour lifetime at that temperature. Physical dimensions remain compatible with the original footprint. This part is recommended when thermal margin improvement is required without design modification.

ECA-1AHG472B (Panasonic NHG-A) offers extended operating temperature range (-55°C to 105°C) and maintains Active product status. Slightly reduced ripple current capacity at 120 Hz (1.26 A) compared to the original. Suitable for applications requiring wider temperature operation.

EEU-FS1A472B (Panasonic FS-A) provides the highest ripple current capacity (2.552 A @ 120 Hz, 3.19 A @ 100 kHz) and extended lifetime (10000 hours @ 105°C). Recommended for high-ripple-current applications or designs requiring extended operational life. Maintains Active product status.

EEU-HD1C472B (Panasonic HD) operates at 16 V rating, providing voltage margin above the 10 V requirement. Extended temperature range (-55°C to 105°C) and Active product status. Suitable when voltage headroom is beneficial for circuit reliability.

Legacy Substitutes (Not For New Designs)

UVK1A472MHD1TO and UVR1A472MHD1TO (Nichicon) are classified as Not For New Designs. These parts maintain electrical equivalence but should not be selected for new product development. Use only when existing inventory must be consumed or when design refresh is not feasible.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor (EEU-HD1C472B) in place of the 10 V original?

A: Yes. Higher voltage ratings are backward compatible. The 16 V capacitor will function correctly in a 10 V circuit. This substitution provides additional voltage margin and may improve circuit reliability under transient conditions.

Q: What is the difference between the Nichicon UVK and UVR series?

A: Both UVK1A472MHD1TO and UVR1A472MHD1TO share identical electrical specifications (4700 µF, 10 V, 2000 Hrs @ 85°C) and physical dimensions. The primary difference is series designation. Both are classified as Not For New Designs and should be avoided in new product development.

Q: Which substitute offers the best ripple current performance?

A: EEU-FS1A472B (Panasonic FS-A) provides the highest ripple current capacity at 2.552 A @ 120 Hz and 3.19 A @ 100 kHz. This part is recommended for applications with high AC ripple current requirements.

Q: Are there physical dimension differences between substitutes?

A: Yes. The original 860010278024 has a diameter of 0.512" (13.00 mm) and height of 1.043" (26.50 mm). All substitute parts except 860020278025 have reduced diameter (0.492" / 12.50 mm) and slightly increased height (1.063" / 27.00 mm). Verify PCB layout clearance before substitution.

Q: Which substitute has the longest operational lifetime?

A: EEU-FS1A472B provides 10000 hours @ 105°C, compared to 2000 hours @ 85°C for the original. This extended lifetime is achieved through improved internal design and is suitable for applications requiring long-term reliability.

Q: Can I use these substitutes interchangeably in production?

A: No. While all listed parts meet the core electrical requirements (4700 µF, 10 V, ±20% tolerance), they differ in ripple current capacity, temperature performance, and product status. Select the specific part that matches your application's thermal, ripple current, and lifecycle requirements.

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

A: This designation indicates the manufacturer is phasing out the product. While the part remains functional and available, it should not be selected for new product development. Use Active-status alternatives for new designs to ensure long-term supply availability.
