Engineering Selection Recommendations

Both the original 860010772001 and substitute 860020772001 are classified as Obsolete products. Selection between these parts should be based on application-specific thermal requirements and ripple current handling capacity.

The 860010772001 operates within a -40°C to 85°C temperature range with a 2000-hour lifetime at 85°C. The 860020772001 extends the operating temperature range to -40°C to 105°C with a 2000-hour lifetime at 105°C, providing enhanced thermal performance for applications subject to elevated ambient temperatures or thermal stress conditions.

The ripple current specifications differ between the two parts. The 860010772001 supports 4 mA at 120 Hz and 6.8 mA at 100 kHz, while the 860020772001 supports 1.3 mA at 120 Hz and 2.21 mA at 100 kHz. Applications requiring higher ripple current handling should retain the original 860010772001 specification.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility. Direct mechanical and electrical interchangeability is confirmed for capacitance, voltage rating, tolerance, polarization, and package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 860020772001 directly replace the 860010772001 in all applications?

A: Direct mechanical and electrical replacement is possible for applications operating within the -40°C to 85°C temperature range. The substitute part maintains identical capacitance (0.1 µF), voltage rating (63 V), tolerance (±20%), and physical dimensions. However, applications requiring the higher ripple current specifications of the original part should evaluate the reduced ripple current capacity of the substitute before implementation.

Q: What is the primary difference between these two parts?

A: The primary differences are the operating temperature range and ripple current specifications. The 860020772001 supports operation up to 105°C compared to 85°C for the 860010772001, and provides a 2000-hour lifetime at the higher temperature. The ripple current capacity is lower in the substitute part across both frequency ranges.

Q: Are both parts suitable for new designs?

A: Both parts are classified as Obsolete. For new designs, consultation with Würth Elektronik is recommended to identify current-generation aluminum electrolytic capacitors with equivalent or superior specifications.

Q: Do the parts have identical physical dimensions?

A: Yes. Both parts share identical lead spacing (0.079" / 2.00 mm), case diameter (0.197" / 5.00 mm), and seated height (0.492" / 12.50 mm). PCB layout and mechanical clearance requirements are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical REACH and ECCN classifications.
