Substitute Part Grouping Explanation

Substitution of the 860010272001 is determined by the following criteria:

Direct Equivalents maintain identical capacitance (22 µF), tolerance (±20%), voltage rating (10 V), and mechanical dimensions while varying thermal performance characteristics or series designation.

Voltage Upgrades increase the rated voltage from 10 V to 16 V, 25 V, 35 V, or 50 V while maintaining 22 µF capacitance and ±20% tolerance. These are suitable when circuit voltage margins require enhancement.

Thermal Performance Upgrades extend the rated lifetime from 2000 hours at 85°C to 2000 hours at 105°C, enabling operation in higher ambient temperature environments.

Combined Upgrades provide both increased voltage rating and extended thermal performance in a single part number.

All substitute parts maintain identical mechanical compatibility (lead spacing, case diameter, height, through-hole mounting) and comply with ROHS3 and REACH requirements.

Engineering Selection Recommendations

Direct Thermal Upgrade: The 860020272001 provides identical electrical specifications to the 860010272001 with extended thermal performance (105°C vs. 85°C). This part is suitable for applications requiring enhanced reliability in elevated ambient temperature environments while maintaining the original 10 V voltage rating.

Voltage Margin Enhancement: Parts 860010372002, 860010472003, 860010572003, and 860010672010 increase voltage ratings to 16 V, 25 V, 35 V, and 50 V respectively. These are applicable when circuit design requires additional voltage safety margins or when operating conditions exceed the original 10 V specification.

Combined Thermal and Voltage Upgrades: Parts 860020372002, 860020472004, 860020572004, 860020672011, and 860020773011 combine elevated voltage ratings with extended thermal performance (105°C). These are suitable for demanding applications requiring both voltage margin and thermal robustness.

Mechanical Compatibility Note: Part 860020773011 features a larger case diameter (0.248" vs. 0.197") due to its 63 V rating. Verify PCB layout compatibility before selection.

All substitute parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can 860020272001 be used as a direct replacement for 860010272001?

A: Yes. The 860020272001 maintains identical capacitance (22 µF), voltage rating (10 V), tolerance (±20%), and mechanical dimensions. The primary difference is extended thermal performance (2000 hours at 105°C vs. 85°C), making it suitable for higher ambient temperature applications.

Q: What is the difference between WCAP-ATG8 and WCAP-ATG5 series?

A: WCAP-ATG8 series is rated for 2000 hours at 85°C maximum temperature. WCAP-ATG5 series extends this to 2000 hours at 105°C. Both series maintain identical mechanical compatibility and electrical specifications at their respective voltage ratings.

Q: Can I use a higher voltage rated part as a substitute?

A: Yes. A capacitor rated for higher voltage (e.g., 860010372002 at 16 V) can replace a lower voltage rated part (860010272001 at 10 V) in the same circuit. The higher voltage rating provides additional safety margin. Verify that the mechanical dimensions are compatible with your PCB layout.

Q: Is 860020773011 mechanically compatible with the original 860010272001?

A: No. The 860020773011 has a larger case diameter (0.248" vs. 0.197") due to its 63 V rating. PCB layout verification is required before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 860010272001.

Q: What ripple current specifications apply to substitute parts?

A: Ripple current values vary by part number and voltage rating. Consult the detailed specifications for each substitute part to confirm ripple current performance at your operating frequency (120 Hz or 100 kHz) meets circuit requirements.
