Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 890324027025CS are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Capacitance value: 3.3 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: 1.220" L x 0.610" W with 1.083" lead spacing (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ratings classification: X2 (exact match required)

Secondary Allowable Variation:

• Voltage Rating - AC: Substitutes with equal or higher voltage ratings are acceptable. The main part operates at 275V AC; substitutes rated at 310V AC provide enhanced voltage margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. The 890324027025 provides direct parametric equivalence with identical voltage rating (275V AC) and series designation (WCAP-FTX2). The 890334027025 and 890334027025CS variants operate at 310V AC within the WCAP-FTXX series, offering increased voltage margin while preserving all mechanical and electrical specifications. Selection between 275V and 310V rated variants depends on circuit design requirements and available voltage headroom in the application.

Frequently Asked Questions (FAQ)

Q: Can the 890334027025 or 890334027025CS be used as a direct replacement for the 890324027025CS?

A: Yes. Both 310V-rated variants are functionally equivalent substitutes. They maintain identical capacitance (3.3 µF), tolerance (±10%), dielectric material (polypropylene metallized), physical dimensions (1.220" L x 0.610" W), lead spacing (1.083"), and operating temperature range (-40°C ~ 105°C). The higher voltage rating provides additional safety margin in applications where the circuit voltage does not exceed 310V AC.

Q: What is the difference between the 890324027025 and 890324027025CS?

A: These parts are parametrically equivalent. Both are rated at 275V AC, belong to the WCAP-FTX2 series, and share identical electrical and mechanical specifications. The "CS" designation indicates bulk packaging, while the non-CS variant also uses bulk packaging. Both are suitable for direct substitution.

Q: Are the WCAP-FTX2 and WCAP-FTXX series interchangeable?

A: The 890324027025 and 890324027025CS belong to the WCAP-FTX2 series (275V rating), while the 890334027025 and 890334027025CS belong to the WCAP-FTXX series (310V rating). All four parts are mechanically and electrically compatible substitutes for the specified application parameters. Series designation reflects internal design variations; functional compatibility is determined by the matching parameters listed in this document.

Q: Will substituting a 310V-rated part affect circuit performance?

A: No. A higher voltage rating does not alter capacitance value, tolerance, dielectric properties, or physical form factor. The 310V rating provides increased voltage withstand capability without changing the capacitor's electrical behavior in the circuit.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (890324027025, 890334027025, and 890334027025CS) maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for current manufacturing and assembly processes.
