Equivalent & Substitute Parts for 890324023019CS

Part Overview

The Würth Elektronik 890324023019CS is a 0.068 µF film capacitor rated for 275V AC operation with polypropylene dielectric material and metallized construction. This component is classified as Active product status and is designed for EMI and RFI suppression applications in electronic circuits. The radial through-hole mounting configuration and X2 safety rating make it suitable for AC line filtering and noise suppression in power supply circuits. Substitute parts are necessary when inventory constraints, voltage margin requirements, or series availability necessitate alternative component selection while maintaining circuit performance and safety compliance.

Substitute Part Grouping Explanation

Substitution eligibility for the 890324023019CS is determined by the following critical parameters: capacitance value (0.068 µF), tolerance (±10%), dielectric material (polypropylene metallized), mounting type (through-hole radial), lead spacing (10.00mm), and safety rating (X2). The voltage rating may be equal to or greater than the original specification without functional degradation. All substitute parts must maintain identical physical dimensions, termination type (PC pins), and operating temperature range to ensure mechanical and electrical compatibility within the circuit board layout and thermal environment.

The substitute parts identified are grouped into two categories:

Category 1 - Direct Parametric Equivalent (Same Voltage Rating):

890324023019: Identical specifications to the main part, differentiated only by packaging designation suffix

Category 2 - Voltage-Upgraded Equivalent (Higher Voltage Rating):

890334023019 and 890334023019CS: Rated for 310V AC instead of 275V AC, providing increased voltage margin while maintaining all other electrical and mechanical parameters

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and environmental conformance equivalent to the original component. The 890324023019 variant provides direct substitution with identical electrical specifications and is suitable for applications where the original part number is unavailable.

The 890334023019 and 890334023019CS variants operate at 310V AC rating, providing a 35V margin above the original 275V specification. These parts are mechanically and electrically compatible with circuits designed for the 890324023019CS and may be selected when enhanced voltage headroom is required or when the higher-rated variants offer superior inventory availability. The series designation change from WCAP-FTX2 to WCAP-FTXX reflects internal Würth Elektronik product line differentiation and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can 890334023019CS be used as a direct replacement for 890324023019CS?

A: Yes. The 890334023019CS is mechanically and electrically compatible. The primary difference is the increased AC voltage rating (310V versus 275V). This higher rating does not degrade performance in circuits designed for 275V operation and may provide additional safety margin in applications subject to voltage transients.

Q: What is the difference between 890324023019 and 890324023019CS?

A: Both parts are parametrically identical with 0.068 µF capacitance and 275V AC rating. The difference is the packaging designation suffix (CS versus non-CS). Both are suitable for direct substitution in the same circuit application.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All substitute parts share identical physical dimensions: 0.512" L x 0.276" W (13.00mm x 7.00mm) with 0.394" (10.00mm) lead spacing. They are mechanically interchangeable on circuit boards designed for the original component.

Q: Can these capacitors be used in DC circuits?

A: No. These components are rated for AC operation only. The X2 safety rating and design specifications are specific to AC line filtering and EMI suppression applications. DC voltage rating is not specified for this product category.

Q: What is the significance of the X2 safety rating?

A: The X2 rating indicates these capacitors are approved for use across the AC mains line with a maximum voltage of 275V AC (or 310V AC for the upgraded variants). This rating ensures the component meets safety standards for direct connection to power supply circuits.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -40°C to 105°C, ensuring thermal compatibility in the same circuit environment.
