Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence in the following parameters: capacitance value, tolerance, physical dimensions (diameter, height, lead spacing), mounting type, and polarization. Voltage rating substitution follows a unidirectional rule: a capacitor with higher voltage rating can substitute for one with lower voltage rating when all other parameters remain identical. Extended lifetime ratings (4000 Hrs vs. 2000 Hrs) represent improved reliability without affecting electrical compatibility. Lead spacing variations (0.079" vs. 0.098") indicate different mechanical footprints and are not interchangeable without PCB redesign. Manufacturer differences do not affect substitution eligibility when all electrical and mechanical parameters align.

Engineering Selection Recommendations

Direct substitution of 860020472001 is limited to Würth Elektronik parts within the WCAP-ATG5 series that maintain identical lead spacing of 0.079" (2.00mm): 860020572001 (35 V), 860020672008 (50 V), and 860020772008 (63 V). These parts are Active status and ROHS3 compliant, ensuring continued availability and regulatory compliance.

The Würth Elektronik 860160672005 offers extended lifetime (4000 Hrs @ 105°C) at 50 V with identical mechanical footprint, suitable for applications requiring enhanced reliability margins.

Nichicon parts (UPS1E4R7MDD1TD, UPS1H4R7MDD1TD, UPS1J4R7MDD1TD, UPJ1K4R7MDD1TD, UPM1H4R7MDD1TD, UPS2A4R7MDD1TD) feature 0.098" (2.50mm) lead spacing and are classified as Obsolete. These parts are not recommended for new designs due to product status and require PCB layout modification for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a direct replacement? A: Yes, provided all other parameters remain identical. A 35 V, 50 V, or 63 V rated capacitor with matching capacitance, tolerance, dimensions, and lead spacing functions correctly in a 25 V circuit. Higher voltage rating provides additional safety margin without affecting circuit operation.

Q: What is the significance of lead spacing differences? A: Lead spacing determines PCB hole pattern compatibility. The 860020472001 uses 0.079" (2.00mm) spacing. Nichicon parts use 0.098" (2.50mm) spacing and require different PCB footprints. These are not mechanically interchangeable without PCB redesign.

Q: Why are Nichicon parts listed as Obsolete? A: Obsolete status indicates these parts are no longer in active production. While inventory may be available, long-term sourcing is not guaranteed. Active status parts from Würth Elektronik are recommended for new designs.

Q: Does manufacturer matter for substitution? A: Manufacturer does not affect electrical or mechanical compatibility when all specified parameters match. However, product status (Active vs. Obsolete) impacts long-term availability and supply chain reliability.

Q: What does ROHS3 compliance mean? A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive requirements, confirming absence of restricted materials. All listed parts maintain this compliance.

Q: Can I substitute a 2000 Hrs lifetime part with a 4000 Hrs lifetime part? A: Yes. Extended lifetime represents improved reliability and does not affect electrical compatibility. The 860160672005 (4000 Hrs @ 105°C) is a direct upgrade to 860020472001 in terms of reliability margin.
