Key Parameters

Substitute Part Grouping Explanation

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

• Capacitance Value: Must match exactly at 4700 µF
• Voltage Rating: Must match exactly at 16 V
• Tolerance: Must match at ±20%
• Package Configuration: Must be Radial, Can with identical lead spacing (0.295" / 7.50 mm)
• Mounting Type: Must be Through Hole
• Polarization: Must be Polar
• Operating Temperature Range: Must encompass -55°C to 105°C minimum
• Compliance: Must maintain ROHS3 compliance and REACH Unaffected status

The Nichicon UPW1C472MHD6TN satisfies all mandatory substitution criteria. Physical dimensions remain compatible with existing PCB layouts, and electrical characteristics remain within acceptable operational parameters for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (860160381045): Würth Elektronik WCAP-ATLL series. Active product status with 1034 units in stock. Suitable for new designs and production applications requiring established supply chain reliability.

Substitute Component (UPW1C472MHD6TN): Nichicon UPW series. Product status is Not For New Designs. This component is suitable for replacement applications, field service, and legacy system maintenance where the primary component is unavailable. The substitute offers extended lifetime (8000 hours versus 7000 hours at 105°C) and lower impedance (20 mOhms versus 55 mOhms), providing improved performance characteristics in existing circuit topologies.

Both components maintain full ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across all markets.

Frequently Asked Questions (FAQ)

Q: Can UPW1C472MHD6TN be used as a direct replacement for 860160381045?

A: Yes. Both components share identical capacitance (4700 µF), voltage rating (16 V), tolerance (±20%), lead spacing (0.295" / 7.50 mm), and mounting configuration (Through Hole, Radial Can). Physical dimensions are compatible with existing PCB layouts. The maximum seated height difference is 0.020" (0.50 mm), which remains within standard PCB assembly tolerances.

Q: What is the difference in lifetime specifications?

A: The Nichicon UPW1C472MHD6TN provides 8000 hours at 105°C compared to 7000 hours for the Würth Elektronik 860160381045. This represents a 14% increase in rated operational lifetime under maximum temperature conditions.

Q: Are there impedance differences that affect circuit performance?

A: The Nichicon substitute exhibits lower impedance (20 mOhms versus 55 mOhms at 100 kHz). Lower impedance generally improves high-frequency ripple current handling and reduces voltage drop across the capacitor. This characteristic is beneficial in power supply and filtering applications.

Q: Why is the Nichicon part marked "Not For New Designs"?

A: Product status reflects manufacturer lifecycle management. The Nichicon UPW series is suitable for replacement and maintenance applications but is not recommended for new product development. For new designs, the Würth Elektronik 860160381045 (Active status) is the preferred selection.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both 860160381045 and UPW1C472MHD6TN are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
