Substitute Part Grouping Explanation

Substitution of the 860010272005 is determined by the following critical parameters:

Capacitance Value: Must remain 100 µF
Voltage Rating: Minimum 10 V (higher ratings are acceptable as upgrades)
Tolerance: ±20% (standard for aluminum electrolytic capacitors)
Package Dimensions: Lead spacing 0.079" (2.00 mm), diameter 0.197" (5.00 mm), height 0.492" (12.50 mm)
Mounting Type: Through Hole configuration
Polarization: Polar

Substitute parts are grouped into two categories:

Direct Substitutes maintain identical voltage ratings (10 V) and may offer extended operating temperature ranges or improved lifetime specifications while preserving mechanical and electrical compatibility.

Upgrade Substitutes feature higher voltage ratings (16 V) or extended temperature ranges (-55°C to 105°C) while maintaining the same capacitance, tolerance, and physical dimensions. These provide enhanced performance margins for demanding applications.

Engineering Selection Recommendations

Würth Elektronik WCAP-ATG5 Series (860020272005, 860020372006): These parts are Active status components offering extended operating temperature capability to 105°C compared to the original 85°C maximum. The WCAP-ATG5 series maintains identical physical dimensions and lead spacing, ensuring direct mechanical compatibility. Selection is appropriate when thermal margin improvement is required without voltage rating changes.

Würth Elektronik WCAP-ATUL Series (860040272001): This Active status part provides doubled lifetime specification (4000 hours at 105°C versus 2000 hours at 85°C) while maintaining 10 V voltage rating and identical package dimensions. The WCAP-ATUL series is suitable for applications requiring extended operational life in elevated temperature environments.

Würth Elektronik WCAP-ATLI and WCAP-ATLL Series (860080272003, 860160272009, 860160372011): These Active status components extend the lower operating temperature limit to -55°C, enabling use in extreme cold environments. The WCAP-ATLL series additionally provides 4000-hour lifetime at 105°C with 16 V voltage rating upgrade, offering maximum performance margin.

Voltage Rating Upgrades (860010372006, 860020372006, 860160372011): These 16 V rated parts are electrically compatible with 10 V circuit requirements and provide additional voltage safety margin. All maintain identical capacitance, tolerance, and physical dimensions.

Nichicon UHE1A101MDD1TD and UPS1A101MDD1TD: These parts are classified as Obsolete and should not be selected for new designs. Lead spacing differs at 0.098" (2.50 mm) versus the original 0.079" (2.00 mm), requiring PCB layout modification.

Rubycon 10YXF100MEFCT15X11: This part carries "Not For New Designs" status and features non-standard lead spacing of 0.098" (2.50 mm), necessitating PCB redesign for implementation.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor in place of the 10 V original?

A: Yes. Higher voltage ratings are electrically compatible with lower voltage circuit requirements. The 16 V parts (860010372006, 860020372006, 860160372011) provide additional voltage safety margin and are direct mechanical substitutes with identical package dimensions and lead spacing.

Q: What is the difference between WCAP-ATG8, WCAP-ATG5, WCAP-ATUL, WCAP-ATLI, and WCAP-ATLL series?

A: These series differ in lifetime specifications and operating temperature ranges. WCAP-ATG8 provides 2000 hours at 85°C with -40°C to 85°C range. WCAP-ATG5 extends to 105°C operation. WCAP-ATUL and WCAP-ATLL offer 4000-hour lifetimes at 105°C. WCAP-ATLI and WCAP-ATLL extend the lower temperature limit to -55°C for cold environment applications.

Q: Are Nichicon UHE1A101MDD1TD and UPS1A101MDD1TD suitable replacements?

A: These Nichicon parts are classified as Obsolete and carry different lead spacing (0.098" versus 0.079"). While electrically compatible, they require PCB layout modification and should not be selected for new designs.

Q: Why does Rubycon 10YXF100MEFCT15X11 show "Not For New Designs" status?

A: This part is in end-of-life phase and carries non-standard lead spacing of 0.098" (2.50 mm) compared to the original 0.079" (2.00 mm). New designs should utilize Active status Würth Elektronik alternatives.

Q: What is the impact of different lead spacing on PCB compatibility?

A: Lead spacing of 0.079" (2.00 mm) versus 0.098" (2.50 mm) requires different PCB pad patterns. Parts with matching 0.079" (2.00 mm) lead spacing (all Würth Elektronik WCAP series) are direct mechanical substitutes. Parts with 0.098" (2.50 mm) spacing require PCB redesign.

Q: Which substitute offers the best reliability for high-temperature applications?

A: The Würth Elektronik WCAP-ATLL series (860160272009 at 10 V, 860160372011 at 16 V) provides the highest reliability specification with 4000-hour lifetime at 105°C and extended temperature range of -55°C to 105°C, all while maintaining Active product status.

Q: Are all recommended substitutes ROHS3 compliant?

A: All Würth Elektronik WCAP series substitutes maintain ROHS3 compliance and REACH Unaffected status consistent with the original 860010272005 component.
