Substitute Part Grouping Explanation

The substitute part 861141483004 is qualified as a direct equivalent based on the following matching parameters:

• Capacitance: 120 µF (identical)
• Tolerance: ±20% (identical)
• Voltage - Rated: 450 V (identical)
• Lead Spacing: 0.394" (10.00mm) (identical)
• Size / Dimension: 0.866" Dia (22.00mm) (identical)
• Height - Seated (Max): 1.693" (43.00mm) (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial, Can - Snap-In (identical)
• Polarization: Polar (identical)
• RoHS Status: ROHS3 Compliant (identical)

The substitute part differs in thermal performance characteristics, offering extended lifetime and higher maximum operating temperature, which represents an enhancement rather than a limitation for most applications.

Parameter Comparison

Engineering Selection Recommendations

Both parts are Active status components from Würth Elektronik with ROHS3 compliance and REACH unaffected status. The 861141483004 substitute provides extended thermal performance with 3000 hours lifetime at 105°C compared to 2000 hours at 85°C for the main part, and supports operation up to 105°C versus 85°C maximum. Selection between these parts depends on application thermal requirements and ripple current specifications. Both parts maintain identical mechanical footprint and electrical ratings for capacitance and voltage, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can 861141483004 be used as a direct replacement for 861011483005?

A: Yes. Both parts share identical capacitance (120 µF), voltage rating (450 V), tolerance (±20%), and mechanical dimensions including lead spacing, diameter, and height. The snap-in radial can package and through-hole mounting are identical, ensuring PCB compatibility without layout modifications.

Q: What are the key differences between these parts?

A: The primary differences are thermal performance metrics. The 861141483004 offers 3000 hours lifetime at 105°C maximum operating temperature, while the 861011483005 provides 2000 hours lifetime at 85°C maximum operating temperature. Ripple current specifications also differ: the 861011483005 supports higher ripple current at both 120 Hz (1.19 A vs 800 mA) and 100 kHz (1.6422 A vs 1.104 A).

Q: Which part should be selected for high-temperature applications?

A: The 861141483004 is suitable for applications requiring operation at temperatures up to 105°C. The 861011483005 is limited to 85°C maximum operating temperature.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. No compliance differences exist between the two parts.

Q: Will either part require PCB layout changes?

A: No. Both parts have identical lead spacing (0.394" / 10.00mm), diameter (0.866" / 22.00mm), and height (1.693" / 43.00mm), ensuring direct footprint compatibility without PCB modifications.
