Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 890324026027CS is determined by the following critical parameters: capacitance value (1 µF), tolerance (±10%), dielectric material (polypropylene metallized), mounting type (through hole radial), physical dimensions, lead spacing, and safety rating (X2). Voltage rating represents the primary differentiator among available substitutes.

The substitute parts are grouped into two categories:

Direct Electrical Equivalent (Same Voltage Rating): Part 890324026027 maintains identical electrical specifications including 275V AC rating, capacitance, tolerance, and dielectric material. This part differs only in packaging designation (bulk without "CS" suffix).

Higher Voltage Rated Equivalents (Upgraded Voltage Rating): Parts 890334026027 and 890334026027CS feature 310V AC rating instead of 275V, representing a voltage upgrade while maintaining all other electrical and mechanical parameters. These parts belong to the WCAP-FTXX series versus the WCAP-FTX2 series of the main part.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active production status and full ROHS3 compliance, ensuring regulatory continuity for new designs and production environments. The 890324026027 provides direct substitution with identical electrical specifications and is suitable for applications requiring the original 275V AC rating specification.

The 890334026027 and 890334026027CS represent voltage-upgraded alternatives, offering 310V AC rating while preserving all other electrical and mechanical characteristics. These parts are applicable in designs where the circuit voltage margin permits higher-rated components or where supply chain optimization favors the WCAP-FTXX series. The "CS" suffix designation on 890334026027CS and 890324026027CS indicates packaging variant classification without affecting electrical performance.

Selection between substitute parts depends on circuit voltage requirements and design specifications. All substitutes maintain identical capacitance, tolerance, dielectric material, temperature range, physical dimensions, and lead spacing, ensuring PCB layout compatibility and functional equivalence within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can 890334026027 or 890334026027CS replace 890324026027CS in a 275V AC circuit?

A: Yes. Both 310V-rated parts are electrically and mechanically compatible with the 275V-rated main part. The higher voltage rating provides additional safety margin in the same physical package. All other parameters—capacitance, tolerance, dielectric material, dimensions, and lead spacing—are identical.

Q: What is the difference between 890324026027CS and 890324026027?

A: Both parts are identical in electrical and mechanical specifications. The "CS" suffix indicates a packaging designation variant. Both maintain 275V AC rating, 1 µF capacitance, and identical physical dimensions.

Q: Are the 890334026027 and 890334026027CS interchangeable?

A: Yes. These parts differ only in packaging designation (CS suffix). Both feature 310V AC rating and are mechanically and electrically identical in all other parameters.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All four parts share identical lead spacing (0.886" / 22.50mm), physical dimensions (1.024" L × 0.433" W), and radial through-hole mounting configuration. PCB layout compatibility is maintained across all substitutes.

Q: What applications are these capacitors designed for?

A: These 1 µF film capacitors are specified for EMI and RFI suppression applications with X2 safety rating, suitable for AC line filtering and noise suppression circuits.
