Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 890324028008CS are identified based on the following critical parameters that determine functional interchangeability:

Matching Parameters (Required for Substitution):

• Capacitance: 6.8 µF
• Tolerance: ±10%
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 105°C
• Mounting Type: Through Hole
• Package / Case: Radial
• Physical Dimensions: 41.50mm L x 22.50mm W
• Height - Seated (Max): 36.00mm
• Lead Spacing: 37.50mm
• Termination: PC Pins
• Ratings: X2
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Voltage Rating - AC: Higher ratings (310V) are acceptable substitutes for 275V applications, as they provide increased safety margin and are backward compatible in circuits designed for lower voltage operation.

The substitute parts 890334028008 and 890334028008CS belong to the WCAP-FTXX series and maintain identical mechanical and electrical characteristics except for elevated AC voltage rating, making them suitable replacements in applications where the original 275V specification can accommodate the higher 310V rated component.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (890334028008 and 890334028008CS) are active production components with ROHS3 compliance, matching the regulatory status of the main part. The primary distinction between the main part and substitutes is the AC voltage rating elevation from 275V to 310V.

Selection between 890324028008CS and its substitutes should be based on circuit voltage requirements. The 310V rated alternatives provide increased voltage margin and are electrically compatible with applications designed for 275V operation. All three parts maintain identical mechanical form factors, thermal characteristics, and dielectric properties, ensuring direct PCB compatibility without layout modifications.

Inventory availability differs across the three options, with 890334028008 offering the highest stock level at 912 units.

Frequently Asked Questions (FAQ)

Q: Can I use the 890334028008 or 890334028008CS as a direct replacement for the 890324028008CS?

A: Yes. Both substitute parts maintain identical capacitance (6.8 µF), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 105°C), and physical dimensions (41.50mm x 22.50mm, 36.00mm height, 37.50mm lead spacing). The 310V AC rating of the substitutes is compatible with 275V applications, providing additional voltage safety margin.

Q: What is the difference between 890334028008 and 890334028008CS?

A: Both parts are electrically and mechanically identical 310V rated 6.8 µF film capacitors. The primary difference is series designation (WCAP-FTXX) and inventory availability. 890334028008 has 912 units in stock, while 890334028008CS has 744 units in stock.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts share identical physical dimensions, lead spacing (37.50mm), and radial through-hole mounting configuration. PCB footprints and assembly processes require no modification.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and maintain X2 ratings. Regulatory and environmental compliance is equivalent across the main part and substitutes.

Q: Why would I choose the 275V rated part over the 310V alternatives?

A: Component selection should align with circuit design specifications. If the application is specifically designed for 275V operation and inventory of the original part is available, maintaining the original specification may be preferred for design consistency and documentation purposes.
