Würth Elektronik 860010478019 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 860010478019 is a 1500 µF, 25 V aluminum electrolytic capacitor in radial configuration with a rated lifetime of 2000 hours at 85°C. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications (capacitance, voltage rating, tolerance, polarization) and mechanical compatibility (lead spacing, package type, mounting configuration) are maintained across different manufacturers or enhanced performance variants within the same electrical class.

Substitute Part Grouping Explanation

Substitution eligibility for the 860010478019 is determined by strict equivalence in the following parameters: capacitance value (1500 µF), voltage rating (25 V), tolerance (±20%), polarization (polar), and mechanical compatibility (radial can package, 0.197" lead spacing, through-hole mounting). Substitute parts are grouped into two categories:

Direct Substitutes: Parts maintaining identical electrical specifications and mechanical dimensions with potential variations in thermal performance or series designation.

Upgrade Substitutes: Parts exceeding the baseline thermal performance (extended lifetime at elevated temperature or expanded operating temperature range) while maintaining all core electrical and mechanical parameters.

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the main part 860010478019. Selection between direct and upgrade substitutes is determined by application thermal requirements and operating environment specifications.

The Würth Elektronik 860020478020 provides direct substitution with extended upper operating temperature to 105°C while maintaining identical mechanical footprint and lead spacing.

The Würth Elektronik 860160478030 offers upgrade performance with 7000-hour lifetime rating at 105°C and expanded lower operating temperature to -55°C, suitable for applications requiring extended thermal durability.

The Rubycon 25ZLJ1500MGA12.5X20 and Panasonic EEU-FR1E152B both provide 10000-hour lifetime ratings at 105°C. Minor dimensional variations exist: both feature 0.492" diameter (12.50 mm) versus 0.512" (13.00 mm) on the main part, and 0.866" height (22.00 mm) versus 0.846" (21.50 mm). These dimensional differences remain within radial can package classification and do not affect electrical performance or lead spacing compatibility.

Frequently Asked Questions (FAQ)

Q: Can 860020478020 be used as a direct replacement for 860010478019?

A: Yes. Both parts share identical capacitance (1500 µF), voltage rating (25 V), tolerance (±20%), lead spacing (0.197" / 5.00 mm), and mechanical package dimensions. The 860020478020 extends the upper operating temperature limit to 105°C and increases the rated lifetime to 2000 hours at that temperature, making it suitable for applications operating at higher ambient temperatures.

Q: What are the dimensional differences between the main part and the Rubycon/Panasonic substitutes?

A: The Rubycon 25ZLJ1500MGA12.5X20 and Panasonic EEU-FR1E152B both feature a 0.492" (12.50 mm) diameter versus 0.512" (13.00 mm) on the 860010478019, and a height of 0.866" (22.00 mm) versus 0.846" (21.50 mm). Lead spacing remains constant at 0.197" (5.00 mm) across all parts. These dimensional variations are within radial can package tolerances and do not affect PCB layout compatibility or electrical function.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts are through-hole mounted radial can capacitors with identical lead spacing of 0.197" (5.00 mm), ensuring PCB footprint compatibility with the original 860010478019.

Q: Which substitute offers the longest operational lifetime?

A: Both the Rubycon 25ZLJ1500MGA12.5X20 and Panasonic EEU-FR1E152B provide 10000-hour lifetime ratings at 105°C, representing the highest thermal durability among the listed substitutes.

Q: Do all parts comply with RoHS and REACH regulations?

A: Yes. All listed parts, including the main part 860010478019, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
