Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1206Y5000222MXT is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 2200 pF
• Temperature coefficient: X7R
• Package designation: 1206 (3216 Metric)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C to 125°C minimum
• Soft termination feature requirement
• RoHS3 compliance status

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 500V
• Tolerance: Equal to or tighter than ±20%
• Physical dimensions: Within 1206 package specification limits
• MSL rating: Equal to or lower than 1

The substitute part CS1206KKX7RZBB222 meets all mandatory matching criteria and provides enhanced electrical performance through higher voltage rating (630V) and improved tolerance (±10%), making it functionally compatible for direct replacement in applications requiring the 1206Y5000222MXT.

Parameter Comparison

Engineering Selection Recommendations

The CS1206KKX7RZBB222 from YAGEO qualifies as a direct substitute for the 1206Y5000222MXT based on electrical and mechanical parameter alignment. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent handling and storage requirements. The substitute part provides enhanced performance margins through higher voltage rating (630V versus 500V) and tighter capacitance tolerance (±10% versus ±20%), making it suitable for applications where the original part is specified. Physical compatibility is confirmed through identical length and width dimensions, with the substitute thickness of 0.071" remaining within standard 1206 package specifications. Selection between these parts should be based on availability, cost considerations, and specific circuit design margins rather than functional compatibility constraints.

Frequently Asked Questions (FAQ)

Q: Can CS1206KKX7RZBB222 be used as a direct replacement for 1206Y5000222MXT?

A: Yes. Both parts share identical capacitance (2200 pF), temperature coefficient (X7R), package type (1206), and operating temperature range (-55°C to 125°C). The substitute meets or exceeds all electrical specifications and maintains equivalent compliance certifications.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (630V versus 500V), capacitance tolerance (±10% versus ±20%), and maximum thickness (0.071" versus 0.063"). The substitute provides higher voltage margin and tighter tolerance, both favorable for circuit performance.

Q: Are there any physical compatibility concerns with the substitute part?

A: No. Both parts use identical 1206 (3216 Metric) package dimensions for length and width (0.126" x 0.063"). The substitute thickness of 0.071" is within standard 1206 package specifications and compatible with standard PCB assembly processes.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating identical moisture handling and storage requirements with no shelf-life limitations.

Q: Are compliance certifications equivalent between these parts?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for use in restricted substance applications.

Q: Which part should be selected for new designs?

A: Selection should be based on availability and cost. From an engineering perspective, both parts are functionally equivalent. The substitute part's higher voltage rating and tighter tolerance may provide additional design margin in applications with stringent performance requirements.
