Key Parameters

Substitute Part Grouping Explanation

The Würth Elektronik 861111485024 qualifies as a direct substitute based on the following criteria:

• Identical capacitance value: 120 µF
• Identical tolerance: ±20%
• Identical rated voltage: 450 V
• Identical lifetime specification: 2000 Hrs @ 105°C
• Identical operating temperature range: -25°C ~ 105°C
• Identical ripple current specifications at both 120 Hz and 100 kHz
• Identical lead spacing: 0.394" (10.00 mm)
• Identical diameter: 1.181" (30.00 mm)
• Identical mounting type: Through Hole
• Identical package type: Radial, Can - Snap-In
• Identical RoHS compliance: ROHS3 Compliant

The substitute part belongs to the WCAP-AIL5 series, compared to the WCAP-AIG5 series of the main part. The only dimensional difference is the seated height, which varies between the two parts.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 861021485021 and substitute part 861111485024 are Active status components manufactured by Würth Elektronik with ROHS3 compliance. Selection between these parts should be based on physical space constraints within the assembly. The main part has a maximum seated height of 1.299" (33.00 mm), while the substitute part has a maximum seated height of 1.102" (28.00 mm). Applications with vertical space limitations may benefit from the substitute part's reduced height. Both parts maintain identical electrical performance specifications and are suitable for general purpose applications requiring 120 µF capacitance at 450 V rated voltage.

Frequently Asked Questions (FAQ)

Q: Can 861111485024 be used as a direct replacement for 861021485021?

A: Yes. Both parts share identical electrical specifications including capacitance, voltage rating, tolerance, ripple current ratings, and operating temperature range. The primary difference is the seated height dimension.

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

A: The seated height differs. The 861021485021 has a maximum seated height of 1.299" (33.00 mm), while the 861111485024 has a maximum seated height of 1.102" (28.00 mm). All other dimensions, including lead spacing and diameter, are identical.

Q: Are both parts suitable for the same applications?

A: Yes, both parts are rated for general purpose applications and maintain identical electrical performance across the specified operating temperature range of -25°C to 105°C.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant and maintain Active product status from Würth Elektronik.

Q: Which part should I select if space is limited?

A: If vertical clearance is constrained, the 861111485024 with its reduced seated height of 1.102" (28.00 mm) may be the appropriate choice, provided the assembly layout accommodates the WCAP-AIL5 series form factor.
