Würth Elektronik 890334023021 Film Capacitor - Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 890334023021 is a 0.082 µF film capacitor rated for 310V AC operation, designed for EMI and RFI suppression applications. This radial polypropylene metallized capacitor features a through-hole mounting configuration with PC pin termination. The part is currently active in production with ROHS3 compliance and is suitable for industrial and commercial electronic circuits requiring reliable AC voltage filtering and noise suppression.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component standardization across multiple suppliers or packaging variants.

Substitute Part Grouping Explanation

Substitution for the Würth Elektronik 890334023021 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.082 µF (exact match required)
• Tolerance: ±10% (defines acceptable capacitance range)
• AC Voltage Rating: 310V (minimum threshold for circuit safety)
• Dielectric Type: Polypropylene (PP), Metallized (determines frequency response and stability)
• Mounting Configuration: Through Hole, Radial package with 0.394" (10.00mm) lead spacing (ensures PCB compatibility)
• Termination Style: PC Pins (mechanical and electrical interface requirement)
• Operating Temperature Range: -40°C to 105°C (thermal performance envelope)
• Compliance Standards: ROHS3 Compliant (regulatory requirement)

Substitute parts must match all parameters listed above. Deviations in any single parameter disqualify a part from direct substitution.
