Key Parameters

Substitute Part Grouping Explanation

Substitution of the B32522C0105K000 is determined by the following critical parameters:

• Capacitance value: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polyester PET, Metallized - Stacked (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Physical dimensions and lead spacing: 18.00mm x 5.00mm, 15.00mm lead spacing (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Termination type: PC Pins (exact match required)

The B32522C1105K000 qualifies as a parametric equivalent because it maintains all critical electrical and mechanical parameters while offering an elevated DC voltage rating of 100V compared to the original 63V specification. This higher voltage rating provides additional design margin without altering form factor, capacitance, tolerance, dielectric composition, or thermal characteristics.
