Substitute Part Grouping Explanation

Substitution eligibility for the 860010280028 is determined by the following criteria:

• Identical capacitance value: 10000 µF
• Identical rated voltage: 10 V
• Identical tolerance: ±20%
• Identical polarization: Polar
• Identical package configuration: Radial, Can
• Identical mounting type: Through Hole
• Identical lead spacing: 0.295" (7.50mm)
• Identical physical dimensions: 0.630" Dia (16.00mm), 1.457" (37.00mm) height
• Compliance with ROHS3 and REACH requirements

The substitute part 860020280029 meets all these criteria. Variations in lifetime temperature rating and ripple current specifications do not preclude substitution when the core electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the 860010280028 and 860020280029 are Active status products from Würth Elektronik, maintaining full ROHS3 compliance and REACH unaffected status. The primary distinction between these parts is the operating temperature range and corresponding lifetime rating. The 860020280029 extends the maximum operating temperature to 105°C with a 2000-hour lifetime at that elevated temperature, compared to the 85°C maximum of the 860010280028. Selection between these parts depends on the thermal environment of the application. For applications operating consistently below 85°C, either part is suitable. For applications requiring operation at temperatures between 85°C and 105°C, the 860020280029 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 860020280029 be used as a direct replacement for the 860010280028 in existing designs?

A: Yes. Both parts share identical electrical specifications (10000 µF, 10 V, ±20% tolerance), identical physical dimensions, and identical lead spacing. The through-hole mounting configuration and radial can package are identical. No PCB layout modifications are required.

Q: What is the difference in ripple current ratings between these parts?

A: The 860010280028 is rated for 2.64 A @ 120 Hz and 3.3792 A @ 100 kHz. The 860020280029 is rated for 1.9 A @ 120 Hz and 2.432 A @ 100 kHz. These differences reflect the different thermal performance characteristics of each series but do not affect substitution eligibility when core electrical parameters match.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. Both carry the same ECCN (EAR99) and HTSUS classifications.

Q: Which part should be selected for high-temperature applications?

A: The 860020280029 is specified for operation up to 105°C with a 2000-hour lifetime at that temperature. The 860010280028 is limited to 85°C maximum. For applications requiring sustained operation above 85°C, the 860020280029 is the appropriate selection.

Q: Is the packaging format identical between these parts?

A: Yes. Both parts are supplied in Cut Tape (CT) packaging with identical lead spacing of 0.295" (7.50mm) and identical physical dimensions of 0.630" diameter by 1.457" maximum height.
