Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 890324022017CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Capacitance value: 0.068 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: 10.00mm x 6.00mm (exact match required)
• Lead spacing: 7.50mm (exact match required)
• Termination: PC Pins (exact match required)

Parameters Allowing Variation:

• Voltage Rating - AC: Substitutes with equal or higher voltage ratings are acceptable
• Series designation: May differ (WCAP-FTX2 vs. WCAP-FTXX)
• Manufacturer part number suffix: Variations in suffix notation (CS vs. non-CS) are acceptable when all other parameters align

The substitute parts 890324022017, 890334022017, and 890334022017CS meet the critical parameter requirements. Parts 890334022017 and 890334022017CS feature upgraded AC voltage ratings (310V vs. 275V), providing enhanced voltage margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original component. The 890324022017 provides direct electrical and mechanical equivalence to the 890324022017CS, differing only in part number suffix notation while maintaining identical specifications.

The 890334022017 and 890334022017CS variants offer upgraded AC voltage ratings of 310V compared to the 275V specification of the main part. This voltage elevation provides additional safety margin in applications where the circuit voltage may approach the component's rated limit. The higher voltage rating does not compromise performance at the original 275V operating point and remains compatible with all mechanical and thermal specifications.

Selection between the 275V-rated parts (890324022017CS and 890324022017) and the 310V-rated alternatives (890334022017 and 890334022017CS) depends on circuit voltage requirements and design margin considerations. All four parts are suitable for EMI and RFI suppression applications within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can 890334022017 or 890334022017CS be used as direct replacements for 890324022017CS?

A: Yes. Both parts maintain identical capacitance (0.068 µF), tolerance (±10%), dielectric material (polypropylene metallized), physical dimensions (10.00mm x 6.00mm), lead spacing (7.50mm), and all other mechanical specifications. The 310V AC rating provides equal or superior performance to the 275V specification.

Q: What is the difference between 890324022017CS and 890324022017?

A: These parts are parametrically equivalent. Both feature 0.068 µF capacitance, 275V AC rating, and identical physical dimensions. The suffix notation (CS vs. non-CS) represents packaging or distribution channel designation but does not affect electrical or mechanical performance.

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

A: Yes. All four parts share identical dimensions of 10.00mm x 6.00mm with 12.50mm maximum seated height and 7.50mm lead spacing. PCB layout and mechanical clearance requirements remain unchanged across all substitutes.

Q: What is the significance of the X2 rating?

A: The X2 rating indicates the component's safety classification for AC mains applications, confirming suitability for EMI and RFI suppression in power line filtering circuits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory conformance for applications requiring restricted substance compliance.

Q: Should I select the 310V-rated parts over the 275V-rated parts?

A: Selection depends on circuit voltage specifications. If the application operates at or near 275V AC, the 310V-rated alternatives provide additional voltage margin. If the circuit is designed for 275V operation, either voltage rating is acceptable.
