Substitute Part Grouping Explanation

Substitute parts for the 890324026003CS are grouped based on the following substitution criteria:

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

• Part number 890324026003 matches all electrical and mechanical parameters of the main part, including 275V AC voltage rating, 0.22 µF capacitance, and identical physical dimensions. This part differs only in packaging designation (Bulk vs. standard).

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

• Part numbers 890334026003 and 890334026003CS provide higher voltage rating (310V AC) while maintaining identical capacitance (0.22 µF), tolerance (±10%), dielectric material (Polypropylene metallized), physical dimensions, lead spacing, and operating temperature range. These parts belong to the WCAP-FTXX series and are suitable for applications requiring higher voltage margin.

All substitute parts maintain:

• Identical capacitance value and tolerance
• Identical physical dimensions and lead spacing
• Identical mounting type (Through Hole, Radial)
• Identical dielectric material (Polypropylene, Metallized)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical X2 rating classification
• ROHS3 compliance

Engineering Selection Recommendations

For Direct Replacement (890324026003): Select part number 890324026003 when exact parametric matching is required and packaging designation is the only acceptable variation. This part maintains identical electrical and mechanical specifications with active product status and full ROHS3 compliance.

For Voltage-Margin Applications (890334026003 or 890334026003CS): Select part numbers 890334026003 or 890334026003CS when circuit design permits higher voltage rating (310V AC vs. 275V AC). These parts provide increased voltage margin while maintaining all other electrical and mechanical parameters. Both variants are active products with ROHS3 compliance. The choice between 890334026003 and 890334026003CS depends on packaging requirements.

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory compliance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can 890324026003 be used as a direct replacement for 890324026003CS? A: Yes. Both parts are parametrically identical with matching capacitance (0.22 µF), voltage rating (275V AC), tolerance (±10%), dielectric material (Polypropylene metallized), physical dimensions, lead spacing, and operating temperature range. The difference is packaging designation only.

Q: Are the 310V AC rated parts (890334026003 and 890334026003CS) compatible with circuits designed for 275V AC? A: Yes. The 310V AC rated parts are electrically compatible with 275V AC circuit designs. Higher voltage rating provides additional safety margin and does not affect circuit operation at lower voltage levels. All other electrical and mechanical parameters remain identical.

Q: What is the difference between 890334026003 and 890334026003CS? A: Both parts are parametrically identical with 310V AC rating, 0.22 µF capacitance, and matching physical dimensions. The difference is packaging designation (Bulk vs. standard). Selection depends on procurement and inventory requirements.

Q: Do all substitute parts fit the same PCB footprint? A: Yes. All parts maintain identical physical dimensions (1.024" L x 0.236" W / 26.00mm x 6.00mm), lead spacing (0.886" / 22.50mm), and radial through-hole mounting type. Direct PCB compatibility is confirmed.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed carry ROHS3 compliance certification, ensuring regulatory compliance for applications subject to RoHS requirements.
