Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 890324026020CS are identified based on the following critical parameters:

• Capacitance Value: 0.68 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Lead Spacing: 0.886" (22.50mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Voltage Rating - AC: 275V or higher (equal or greater acceptable)
• Compliance: ROHS3 Compliant, X2 Rating (exact match required)

Two substitute categories exist: direct parametric equivalents at 275V AC and higher-rated variants at 310V AC that maintain all other specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (275V AC Rating):

• 890324026020: Identical electrical and mechanical specifications to the main part. Differs only in packaging designation (no "CS" suffix). Both maintain ROHS3 compliance and Active product status.

Higher Voltage Rated Alternatives (310V AC Rating):

• 890334026020CS and 890334026020: These parts provide increased voltage headroom at 310V AC while maintaining all other electrical and mechanical parameters. The series designation changes from WCAP-FTX2 to WCAP-FTXX. Both are ROHS3 compliant and Active. These are suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

All substitute parts maintain identical physical dimensions, lead spacing, termination type, and temperature operating range, ensuring direct mechanical and electrical compatibility in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can 890324026020 be used as a direct replacement for 890324026020CS? A: Yes. Both parts are parametric equivalents with identical electrical specifications (0.68 µF, ±10%, 275V AC) and mechanical dimensions. The difference is packaging designation only.

Q: What is the difference between the 275V and 310V rated parts? A: The 890334026020CS and 890334026020 are rated for 310V AC compared to 275V AC for the main part. All other specifications—capacitance, tolerance, dielectric material, physical dimensions, and lead spacing—remain identical. The higher voltage rating provides additional safety margin in high-voltage applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (890324026020, 890334026020CS, and 890334026020) are ROHS3 compliant and maintain X2 ratings for EMI/RFI suppression applications.

Q: Can the 310V rated parts be used in place of the 275V rated main part? A: Yes. Higher voltage-rated capacitors are functionally compatible in circuits designed for lower voltage operation. The 310V variants provide equivalent or superior performance in 275V applications.

Q: Do all substitute parts have the same physical footprint? A: Yes. All parts share identical dimensions (1.024" L x 0.295" W, 26.00mm x 7.50mm), height (0.610" / 15.50mm), and lead spacing (0.886" / 22.50mm), ensuring direct PCB compatibility without layout modifications.

Q: What applications are these capacitors designed for? A: These film capacitors are specified for EMI and RFI suppression in electronic circuits. The X2 rating indicates suitability for AC mains filtering applications.
