Substitute Part Grouping Explanation

Substitute parts for the 860010278021 are organized into three categories based on allowed parameter variations:

Direct Substitutes (Same Voltage, Same Lifetime Temperature):

860020278022: Identical electrical specifications (2700 µF, 10 V, ±20%) with extended operating temperature range (-40°C ~ 105°C) and higher ripple current capability. Series WCAP-ATG5 provides equivalent performance at elevated ambient temperatures.

Upgrade Substitutes (Higher Voltage Rating):

860010378022: Upgraded to 16 V rating while maintaining 2700 µF capacitance and ±20% tolerance. Same lifetime (2000 Hrs @ 85°C) and series (WCAP-ATG8). Provides voltage margin for applications requiring higher transient protection.
860020378022: Upgraded to 16 V rating with extended operating temperature (-40°C ~ 105°C) and series WCAP-ATG5. Combines voltage upgrade with thermal performance enhancement.

Extended Lifetime Substitutes (Enhanced Reliability):

860160278040: Maintains 10 V rating and 2700 µF capacitance with significantly extended lifetime (7000 Hrs @ 105°C) and expanded operating temperature range (-55°C ~ 105°C). Series WCAP-ATLL provides superior long-term reliability.
UPA1A272MHD1TO (Nichicon): Cross-manufacturer substitute with identical electrical specifications (2700 µF, 10 V, ±20%) and extended lifetime (5000 Hrs @ 105°C). Operating temperature range -55°C ~ 105°C. Mechanical dimensions vary slightly (0.492" Dia, 0.866" Height).

Substitution Logic: All substitute parts maintain the core electrical parameters (2700 µF capacitance, ±20% tolerance) and mechanical compatibility (lead spacing 5.00 mm, through-hole radial mounting). Substitution is permitted when the substitute part meets or exceeds the original specifications for voltage rating, operating temperature range, and lifetime at rated temperature. Mechanical dimensions remain within acceptable tolerance for standard through-hole PCB layouts.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): Select 860020278022 when inventory of the original 860010278021 is unavailable. This part maintains identical electrical performance with the added benefit of extended operating temperature capability to 105°C, making it suitable for applications with higher ambient thermal conditions.

For Voltage Margin Applications: Select 860010378022 or 860020378022 when circuit design requires higher voltage headroom for transient protection or when operating conditions may expose the capacitor to voltage spikes. The 16 V rating provides additional safety margin while maintaining the same 2700 µF capacitance and mechanical form factor.

For Extended Lifetime Requirements: Select 860160278040 for applications demanding superior long-term reliability. The 7000-hour lifetime at 105°C and expanded temperature range (-55°C ~ 105°C) address demanding industrial or automotive environments. This part is within the same manufacturer family (Würth Elektronik) and maintains identical mechanical compatibility.

For Cross-Manufacturer Substitution: The Nichicon UPA1A272MHD1TO provides equivalent electrical performance with 5000-hour lifetime at 105°C. Mechanical dimensions vary slightly (0.492" diameter, 0.866" height versus 0.512" diameter, 0.846" height). Verify PCB layout clearances before selection. This part is REACH Affected, requiring compliance verification for regulated applications.

All substitute parts are Active product status and ROHS3 compliant, ensuring regulatory compliance and continued availability.

Frequently Asked Questions (FAQ)

Q: Can 860020278022 be used as a direct replacement for 860010278021? A: Yes. Both parts share identical capacitance (2700 µF), tolerance (±20%), and voltage rating (10 V). The 860020278022 extends the operating temperature range to 105°C, making it a compatible direct substitute with enhanced thermal performance.

Q: What is the difference between the 10 V and 16 V rated parts? A: The 16 V rated parts (860010378022 and 860020378022) provide higher voltage margin for transient protection. They maintain the same 2700 µF capacitance and mechanical dimensions. Select 16 V versions when circuit design requires voltage headroom or when operating conditions include voltage spikes.

Q: Why does the Nichicon UPA1A272MHD1TO have different mechanical dimensions? A: The Nichicon part has a slightly smaller diameter (0.492" versus 0.512") and slightly taller height (0.866" versus 0.846"). Lead spacing remains identical at 5.00 mm. Verify PCB layout clearances and hole positioning before substitution.

Q: Which substitute part offers the longest operational lifetime? A: The 860160278040 provides 7000 hours at 105°C, the highest lifetime rating among all listed substitutes. This part is recommended for applications requiring maximum long-term reliability.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant. The Nichicon UPA1A272MHD1TO is REACH Affected, requiring compliance verification for applications subject to REACH regulations.

Q: Can I use a 16 V rated part in place of a 10 V rated part? A: Yes. Higher voltage ratings are backward compatible in applications designed for lower voltages. The 16 V parts (860010378022 and 860020378022) can substitute for 10 V applications without electrical or mechanical issues.

Q: What is the lead spacing for all these parts? A: All parts maintain 0.197" (5.00 mm) lead spacing, ensuring compatibility with standard through-hole PCB layouts designed for the original 860010278021.
