Equivalent & Substitute Parts for 860040375010

Part Overview

The Würth Elektronik 860040375010 is a 1000 µF, 16 V aluminum electrolytic capacitor in radial configuration with a 7000-hour lifetime rating at 105°C. This component is classified as Active product status and is suitable for general-purpose applications requiring through-hole mounting in standard 5.00 mm lead spacing.

Substitute parts are necessary when the primary component becomes unavailable, when design requirements demand extended operational lifetime, or when upgraded voltage ratings are required for enhanced circuit margin. The following equivalent and substitute parts maintain core electrical and mechanical compatibility while offering variations in performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 860040375010 is determined by the following mandatory parameters:

• Capacitance: Must equal 1000 µF
• Voltage Rating: Must be ≥16 V (equal or higher voltage rating is acceptable)
• Tolerance: Must be ±20%
• Polarization: Must be Polar
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial, Can
• Lead Spacing: Must be 0.197" (5.00 mm)
• Case Diameter: Must be 0.394" (10.00 mm)
• Operating Temperature Range: Must support -40°C to 105°C
• RoHS Status: Must be ROHS3 Compliant

All substitute parts listed below satisfy these mandatory criteria. Variations in lifetime rating, impedance, and ripple current capacity are secondary performance characteristics that do not prevent substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (16 V Rating)

The parts 16YXF1000MEFCT810X20, 16ZLJ1000MT810X16, EEU-FR1C102B, and UHE1C102MPD1TD are direct electrical equivalents with identical 16 V voltage rating and 1000 µF capacitance. Selection among these should prioritize Active product status for new designs. The Rubycon 16ZLJ1000MT810X16 and Panasonic EEU-FR1C102B both carry Active status and offer improved performance metrics: the ZLJ series provides extended 10000-hour lifetime and lower impedance (38 mOhms), while the FR-A series (EEU-FR1C102B) offers the lowest impedance at 28 mOhms with 8000-hour lifetime.

Parts marked "Not For New Designs" (16YXF1000MEFCT810X20 and UHE1C102MPD1TD) are suitable only for legacy system maintenance or repair applications where the original part number must be matched.

Upgraded Substitute (25 V Rating)

The Panasonic EEU-FR1E102B operates at 25 V, providing higher voltage margin than the 16 V main part. This part is classified as Active and offers superior performance: 10000-hour lifetime, lowest impedance (20 mOhms), and highest ripple current capacity. This upgrade is applicable when circuit design permits higher voltage rating and when extended operational lifetime is beneficial.

Mechanical Compatibility

All substitute parts maintain the required 5.00 mm lead spacing and 10.00 mm case diameter. Height variations range from 0.689" to 0.866", which may affect PCB layout in space-constrained applications. The Rubycon ZLJ series offers the most compact height at 0.689".

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of a 16 V capacitor?

A: Yes. The Panasonic EEU-FR1E102B (25 V) is a valid substitute for the 860040375010 (16 V). Higher voltage ratings provide additional safety margin and do not degrade circuit performance. The 25 V part occupies the same footprint and maintains all mechanical compatibility requirements.

Q: What is the difference between Active and "Not For New Designs" product status?

A: Active parts are currently manufactured and recommended for new circuit designs. Parts marked "Not For New Designs" are in production but intended only for legacy system support or repair. For new applications, select from Active-status alternatives: 16ZLJ1000MT810X16, EEU-FR1C102B, or EEU-FR1E102B.

Q: Does impedance variation affect substitutability?

A: Impedance differences do not prevent substitution but may influence performance in high-frequency ripple current applications. Lower impedance (20–28 mOhms) provides better high-frequency performance. The main part (860040375010) has 46 mOhms impedance; substitutes range from 20 to 78 mOhms. Verify ripple current requirements against the specific substitute's rated capacity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the main part's environmental compliance. The Nichicon UHE1C102MPD1TD is REACH Affected; all others are REACH Unaffected.

Q: What is the significance of lifetime rating differences?

A: Lifetime rating indicates operational hours at maximum temperature (105°C). The main part is rated 7000 hours; substitutes range from 7000 to 10000 hours. Extended lifetime (10000 hours) provides longer service life in continuous-duty applications. This is a performance enhancement, not a substitution barrier.

Q: Can I substitute based on lead spacing alone?

A: No. Lead spacing (5.00 mm) is necessary but not sufficient for substitution. All mandatory parameters must be matched: capacitance (1000 µF), voltage rating (≥16 V), tolerance (±20%), polarization (Polar), mounting type (Through Hole), package (Radial, Can), case diameter (10.00 mm), and temperature range (-40°C to 105°C).
