Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors in this category is determined by strict equivalence in the following parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Physical dimensions: Lead spacing 10.00 mm, case diameter 22.00 mm, height 28.00 mm (exact match required)
• Operating temperature range: -25°C to 85°C (exact match required)
• Polarization: Polar (exact match required)

The substitute part 861221483002 meets all these criteria. The primary distinction between the main part and its substitute is the rated lifetime at 85°C, which increases from 2000 hours to 3000 hours, representing an upgrade in thermal endurance without modification to electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 861101483003 and 861221483002 are active production parts from Würth Elektronik with identical ROHS3 and REACH compliance certifications. The 861221483002 provides extended thermal lifetime (3000 hours at 85°C versus 2000 hours), making it suitable for applications requiring enhanced reliability in elevated temperature environments. Both parts maintain identical electrical ratings, mechanical dimensions, and mounting specifications, ensuring direct interchangeability in circuit board layouts. Selection between these parts should be based on application lifetime requirements and thermal stress conditions.

Frequently Asked Questions (FAQ)

Q: Can 861221483002 be used as a direct replacement for 861101483003?

A: Yes. Both parts share identical capacitance (82 µF), voltage rating (450 V), tolerance (±20%), physical dimensions (22.00 mm diameter, 28.00 mm height, 10.00 mm lead spacing), mounting type (through hole), and package configuration (radial, can snap-in). The substitute part is mechanically and electrically interchangeable.

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

A: The rated lifetime at 85°C differs: 861101483003 is rated for 2000 hours, while 861221483002 is rated for 3000 hours. This represents an upgrade in thermal endurance without changes to electrical specifications or physical dimensions.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8532.22.0040).

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Lead spacing (10.00 mm), case diameter (22.00 mm), and seated height (28.00 mm) are identical for both parts, ensuring compatibility with existing through-hole pad layouts.

Q: Are ripple current ratings identical?

A: Ripple current ratings are similar but not identical. At 120 Hz, 861101483003 is rated for 890 mA while 861221483002 is rated for 860 mA. At 100 kHz, 861101483003 is rated for 1.3617 A while 861221483002 is rated for 1.3158 A. Both ratings remain within acceptable ranges for general purpose applications.
