Substitute Part Grouping Explanation

Substitution eligibility for the 890324027012CS is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 1.2 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 type: Radial (exact match required)
• Lead spacing: 1.083" (27.50mm) (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ratings classification: X2 (exact match required)

Secondary Substitution Criteria (Allowable Variation):

• Voltage Rating - AC: Equal to or greater than 275V
• Physical dimensions: Identical footprint and height
• Compliance certifications: ROHS3 and REACH status maintained

Parts meeting all primary criteria and maintaining or exceeding secondary criteria are classified as direct parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

890324027012 (Direct Parametric Equivalent): This part is a direct parametric equivalent to the 890324027012CS. All electrical and mechanical specifications are identical, including capacitance, tolerance, voltage rating, dielectric material, operating temperature range, and physical dimensions. Both parts are ROHS3 compliant and maintain active product status. This substitute provides identical circuit performance and PCB compatibility. Higher inventory availability (1138 units) may support supply chain requirements.

890334027012CS (Voltage-Rated Equivalent): This part meets all primary substitution criteria with one secondary parameter variation: the AC voltage rating is 310V compared to the 275V rating of the main part. The higher voltage rating provides additional safety margin in applications operating at or below 275V AC. All other specifications—capacitance, tolerance, dielectric material, temperature range, physical dimensions, and lead spacing—are identical. Both parts are ROHS3 compliant and active. This substitute is suitable for applications where elevated voltage headroom is beneficial or required by design specifications.

Frequently Asked Questions (FAQ)

Q: Can 890324027012 be used as a direct replacement for 890324027012CS? A: Yes. The 890324027012 is a direct parametric equivalent with identical electrical and mechanical specifications. Both parts share the same capacitance (1.2 µF), tolerance (±10%), voltage rating (275V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C to 105°C), and physical footprint. PCB layout and circuit performance remain unchanged.

Q: What is the difference between 890324027012CS and 890334027012CS? A: The primary difference is the AC voltage rating: 890324027012CS is rated for 275V AC, while 890334027012CS is rated for 310V AC. All other parameters—capacitance, tolerance, dielectric material, temperature range, and physical dimensions—are identical. The higher voltage rating of the 890334027012CS provides additional voltage margin and is suitable for applications requiring enhanced voltage headroom.

Q: Can 890334027012CS replace 890324027012CS in a 275V AC application? A: Yes. The 890334027012CS has a higher voltage rating (310V AC) and meets all other electrical and mechanical requirements of the 275V AC application. The elevated voltage rating does not negatively impact circuit performance in lower-voltage applications. Physical dimensions and lead spacing are identical, ensuring PCB compatibility.

Q: Are all three parts ROHS3 compliant? A: Yes. All three parts—890324027012CS, 890324027012, and 890334027012CS—are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these parts have identical physical dimensions? A: Yes. All three parts share identical physical dimensions: 1.220" L x 0.512" W (31.00mm x 13.00mm), with a maximum seated height of 0.886" (22.50mm) and lead spacing of 1.083" (27.50mm). They are mechanically interchangeable on PCBs designed for radial through-hole film capacitors with this footprint.
