Substitute Part Grouping Explanation

Substitute parts for the 890324023023CS are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Physical dimensions: 0.512" L x 0.276" W with 0.394" lead spacing (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ratings classification: X2 (exact match required)

Secondary Consideration:

• Voltage Rating - AC: Substitutes may exceed the original 275V rating, provided all other parameters remain identical. Higher voltage ratings maintain backward compatibility in AC applications.

The substitute parts listed below meet all primary matching criteria. Voltage rating variations are noted in the parameter comparison table.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original component. Selection between substitute options is determined by voltage rating requirements and series availability:

890324023023: Direct parametric equivalent with identical 275V AC rating. Belongs to WCAP-FTX2 series. Use when voltage rating specification is critical to circuit design.

890334023023 and 890334023023CS: Parametric equivalents with elevated 310V AC rating. Belong to WCAP-FTXX series. The higher voltage rating provides additional safety margin in AC applications while maintaining all other electrical and mechanical specifications. 890334023023CS offers significantly higher inventory availability (22413 units) compared to 890334023023 (1759 units).

All substitute parts are suitable for EMI and RFI suppression applications with X2 ratings classification. Physical footprint and lead spacing are identical across all options, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can 890334023023CS substitute for 890324023023CS in my circuit?

A: Yes. Both parts share identical capacitance (0.1 µF), tolerance (±10%), dielectric material (polypropylene metallized), mounting type (through hole radial), physical dimensions (0.512" L x 0.276" W with 0.394" lead spacing), operating temperature range (-40°C ~ 105°C), and X2 ratings. The 890334023023CS features a higher AC voltage rating (310V versus 275V), which is compatible with circuits designed for 275V operation.

Q: What is the difference between WCAP-FTX2 and WCAP-FTXX series?

A: Both series contain 0.1 µF film capacitors with polypropylene metallized dielectric in radial through-hole configuration. The primary difference is voltage rating: WCAP-FTX2 series is rated for 275V AC, while WCAP-FTXX series is rated for 310V AC. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (890324023023, 890334023023, and 890334023023CS) are ROHS3 compliant, matching the compliance status of the original 890324023023CS component.

Q: Can I use a 310V rated capacitor in place of a 275V rated capacitor?

A: Yes. A higher voltage rating provides additional electrical stress margin and is functionally compatible in circuits designed for lower voltage operation. The 890334023023 and 890334023023CS (310V rated) are suitable replacements for the 890324023023CS (275V rated) in AC applications.

Q: Do all substitute parts have identical physical dimensions?

A: Yes. All substitute parts share identical dimensions: 0.512" L x 0.276" W (13.00mm x 7.00mm) with 0.394" (10.00mm) lead spacing and 0.532" (14.60mm) maximum seated height. Direct board-level substitution is supported without layout modifications.

Q: Which substitute part has the best inventory availability?

A: 890334023023CS offers the highest inventory availability with 22413 units in stock, compared to 890324023023 (2506 units), 890334023023 (1759 units), and the main part 890324023023CS (1547 units).
