Substitute Part Grouping Explanation

Substitution eligibility for the Würth Elektronik 860080478021 is determined by the following criteria:

• Capacitance value: 1200 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Physical dimensions: 0.512" diameter × 0.846" height (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Polarization: Polar (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The substitute part Würth Elektronik 860160478029 meets all mandatory electrical and mechanical parameters. Differences in lifetime rating, ripple current specifications, and impedance do not affect substitution eligibility as these represent performance enhancements rather than compatibility constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 860080478021 and 860160478029 are Active products with ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on application-specific requirements:

The 860080478021 (WCAP-ATLI series) provides a 5000-hour lifetime rating at 105°C with lower impedance (25 mOhms) and higher ripple current capability (2.39 A @ 100 kHz).

The 860160478029 (WCAP-ATLL series) provides an extended 10000-hour lifetime rating at 105°C. This part is suitable for applications requiring longer operational life under elevated temperature conditions.

Both parts are mechanically and electrically interchangeable within the specified parameter constraints. Packaging format differs (Tape & Box versus Cut Tape), which may affect procurement and handling procedures but does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 860160478029 be used as a direct replacement for the 860080478021?

A: Yes. Both parts share identical electrical specifications (1200 µF, 25 V, ±20% tolerance) and mechanical dimensions (0.512" diameter, 0.846" height, 5.00 mm lead spacing). The 860160478029 offers extended lifetime (10000 hours versus 5000 hours at 105°C) and is a direct substitute.

Q: What is the difference in packaging between these two parts?

A: The 860080478021 is supplied in Tape & Box (TB) format, while the 860160478029 is supplied in Cut Tape (CT) format. Both are through-hole radial capacitors with identical footprints and mounting requirements.

Q: Are there any impedance or ripple current differences that affect compatibility?

A: The 860160478029 has higher impedance (82 mOhms versus 25 mOhms) and lower ripple current rating (2.028 A versus 2.39 A at 100 kHz). These differences do not prevent substitution but should be evaluated for applications with specific ripple current or impedance requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH Unaffected, meeting equivalent regulatory requirements for this product category.
