Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 860010678023 is determined by the following mandatory parameters:

• Capacitance value of 820 µF (exact match required)
• Voltage rating of 50 V (exact match required)
• Tolerance of ±20% (exact match required)
• Radial, Can package configuration (exact match required)
• Lead spacing of 0.197" (5.00 mm) (exact match required)
• Through Hole mounting type (exact match required)
• Polar electrolytic capacitor (exact match required)

Parts meeting these criteria are considered electrically and mechanically compatible. Performance characteristics such as lifetime rating, operating temperature range, ripple current capacity, and ESR may vary between substitutes and are documented for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

All three parts are classified as Active products and meet ROHS3 compliance requirements. Selection between these substitutes should be based on the following criteria:

860010678023 (Würth Elektronik WCAP-ATG8): Primary specification with baseline thermal performance. Suitable for applications operating within -40°C to 85°C temperature range.

860020678025 (Würth Elektronik WCAP-ATG5): Direct manufacturer alternative with extended operating temperature range to 105°C. Maintains identical physical dimensions and lead spacing. Ripple current capacity is reduced compared to the primary part.

UBY1H821MHL1TO (Nichicon UBY): Extended performance option with operating temperature range to 135°C and 3000-hour lifetime rating at 135°C. Specified ESR of 44 mOhm at 100 kHz provides measurable performance data. Diameter is 0.492" (12.50 mm) versus 0.512" (13.00 mm) for Würth parts. REACH Status is listed as Affected. Ripple current capacity is highest among the three options.

Frequently Asked Questions (FAQ)

Q: Can the UBY1H821MHL1TO be used as a direct replacement for the 860010678023?

A: The UBY1H821MHL1TO meets all mandatory electrical parameters (capacitance, voltage, tolerance, polarization) and mechanical parameters (lead spacing, height, through-hole mounting). However, the can diameter differs by 0.020" (0.50 mm). PCB layout and mechanical clearance must be verified before substitution.

Q: What is the difference between the two Würth Elektronik parts?

A: Both 860010678023 and 860020678025 share identical physical dimensions and lead spacing. The primary differences are operating temperature range (85°C versus 105°C maximum) and ripple current specifications. The 860020678025 is rated for higher temperature operation but with lower ripple current capacity.

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

A: The UBY1H821MHL1TO from Nichicon provides the highest operating temperature rating (-40°C to 135°C) and longest lifetime specification (3000 hours at 135°C). It also offers the highest ripple current capacity at both 120 Hz and 100 kHz.

Q: Are all three parts RoHS compliant?

A: All three parts are ROHS3 Compliant. The UBY1H821MHL1TO has REACH Status listed as Affected, while the Würth Elektronik parts are REACH Unaffected.

Q: What does the ±20% tolerance mean for capacitance?

A: The ±20% tolerance indicates that the actual capacitance value may vary between 656 µF and 984 µF from the nominal 820 µF specification. This tolerance applies equally to all three substitute options.
