Substitute Part Grouping Explanation

Substitute parts for the 890324023007CS are grouped based on strict electrical and mechanical parameter matching:

Group 1 - Direct Parametric Equivalents (275V AC Rating):

• 890324023007: Identical electrical specifications and mechanical dimensions. Differs only in packaging designation (non-CS variant). Same series (WCAP-FTX2), same inventory availability classification.

Group 2 - Voltage-Rated Equivalents (310V AC Rating):

• 890334023007
• 890334023007CS

These parts maintain identical capacitance (0.012 µF), tolerance (±10%), dielectric material (Polypropylene metallized), operating temperature range (-40°C ~ 105°C), and mechanical configuration (radial, through-hole, 10.00mm lead spacing). The distinguishing parameter is the elevated AC voltage rating of 310V, which exceeds the 275V requirement of the main part. These parts belong to the WCAP-FTXX series and are suitable for applications where higher voltage margin is acceptable or required.

Parameter Comparison

Engineering Selection Recommendations

890324023007 (Direct Equivalent): This part is the primary substitute for 890324023007CS. Both maintain identical electrical and mechanical specifications with 275V AC rating. Selection between these two variants depends on packaging and procurement requirements, as both are Active status products with full ROHS3 compliance.

890334023007 and 890334023007CS (Higher Voltage Rating): These parts are suitable substitutes when circuit design permits or requires a higher voltage margin. The 310V AC rating provides additional safety margin above the 275V specification. Both parts maintain identical capacitance, tolerance, dielectric material, and mechanical configuration. These are appropriate for applications where voltage derating or system reliability improvements are prioritized. Both are Active status products with ROHS3 compliance.

All substitute parts are manufactured by Würth Elektronik, maintain X2 safety ratings for EMI/RFI suppression, and are compliant with REACH and EAR99 export classifications.

Frequently Asked Questions (FAQ)

Q: Can 890334023007 or 890334023007CS be used as direct replacements for 890324023007CS?

A: Yes. These parts share identical capacitance (0.012 µF), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and mechanical configuration (radial, through-hole, 10.00mm lead spacing). The 310V AC rating exceeds the 275V requirement, making them electrically compatible. Circuit board layout and lead spacing are identical.

Q: What is the difference between 890324023007CS and 890324023007?

A: Both parts are parametrically identical with 275V AC rating, 0.012 µF capacitance, and matching mechanical dimensions. The difference is in packaging designation (CS variant). Both are Active status products suitable for direct substitution.

Q: Are the 310V-rated parts (890334023007 series) suitable for 275V AC applications?

A: Yes. The 310V AC rating is a higher specification than the 275V requirement. These parts are electrically compatible and provide additional voltage margin. Selection depends on circuit design requirements and availability.

Q: Do all substitute parts have identical physical dimensions?

A: Yes. All listed substitute parts share identical radial package dimensions: 0.512" L x 0.197" W (13.00mm x 5.00mm), with 0.453" (11.50mm) maximum seated height and 0.394" (10.00mm) lead spacing. They are mechanically interchangeable on PCBs designed for the main part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (890324023007, 890334023007, 890334023007CS) are ROHS3 compliant and maintain Active product status with identical environmental and regulatory certifications.

Q: What applications are these capacitors designed for?

A: All parts in this substitution group are rated for EMI and RFI suppression with X2 safety ratings, suitable for power line filtering and electromagnetic interference mitigation in AC circuits.
