Würth Elektronik 860010672001 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 860010672001 is a 0.1 µF aluminum electrolytic capacitor rated at 50 V with ±20% tolerance, designed for general-purpose applications. This radial, through-hole component features a 2000-hour lifetime at 85°C and operates across the temperature range of -40°C to 85°C. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution for the 860010672001 is determined by the following allowable parameters:

Capacitance: Must remain 0.1 µF (exact match required)
Tolerance: Must remain ±20% (exact match required)
Voltage Rating: May be equal to or greater than 50 V (uprating permitted)
Mounting Type: Must remain through-hole radial configuration
Physical Dimensions: Lead spacing, case diameter, and height must match or be compatible with PCB layout
Polarization: Must remain polar (aluminum electrolytic)
Compliance: RoHS3 compliance required

The two substitute parts identified—860010772001 and 860020772001—both maintain the core electrical specifications (0.1 µF, ±20% tolerance) while offering voltage uprating to 63 V. Both are physically compatible with the original part's footprint and mounting requirements.

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the original 860010672001 at the electrical and mechanical levels. The 860010772001 provides a direct upgrade path with identical thermal performance (2000 Hrs @ 85°C) and an increased voltage rating of 63 V, suitable for applications requiring enhanced voltage margin. The 860020772001 extends the operating temperature range to 105°C with the same 2000-hour lifetime specification at the higher temperature, making it appropriate for designs operating in elevated thermal environments.

All three parts are ROHS3 compliant and carry identical HTSUS and ECCN classifications, ensuring regulatory and export compliance consistency. Selection between the substitute options depends on application-specific thermal and voltage requirements rather than functional or compliance constraints.

Frequently Asked Questions (FAQ)

Q: Can 860010772001 or 860020772001 be used as direct replacements for 860010672001?

A: Yes. Both substitute parts maintain the same capacitance (0.1 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting configuration. The higher voltage ratings (63 V versus 50 V) represent an uprating that does not compromise compatibility.

Q: What is the difference between 860010772001 and 860020772001?

A: Both parts share the same electrical specifications and physical footprint. The primary difference is the operating temperature range and corresponding lifetime rating. The 860010772001 operates to 85°C with a 2000-hour lifetime at that temperature. The 860020772001 extends operation to 105°C with a 2000-hour lifetime at 105°C, indicating enhanced thermal performance suitable for higher-temperature applications.

Q: Are there packaging differences between these parts?

A: The main part (860010672001) is supplied in Tape & Box (TB) packaging. Both substitute parts are supplied in Cut Tape (CT) packaging. This difference affects procurement and handling but does not impact electrical or mechanical compatibility.

Q: Do all three parts have the same ripple current ratings?

A: No. The ripple current specifications differ across the three parts. The 860010672001 specifies 3.3 mA @ 120 Hz and 5.61 mA @ 100 kHz. The 860010772001 specifies 4 mA @ 120 Hz and 6.8 mA @ 100 kHz. The 860020772001 specifies 1.3 mA @ 120 Hz and 2.21 mA @ 100 kHz. These differences reflect the thermal design of each variant and should be considered in high-ripple-current applications.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry REACH Unaffected status, meeting current environmental and regulatory requirements.
