CS1206KKX7RDBB102 Equivalent & Substitute Parts

Part Overview

The CS1206KKX7RDBB102 is a 1000 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, manufactured by YAGEO in 1206 (3216 Metric) surface mount package. This component is designed for applications requiring boardflex sensitivity and soft termination characteristics. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on matching electrical specifications, mechanical dimensions, and compliance certifications to ensure direct functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS1206KKX7RDBB102 is determined by the following critical parameters:

• Capacitance value: 1000 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 2000V (2kV) minimum (exact match required)
• Temperature coefficient: X7R (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The identified substitute parts 1206Y2K00102KJT and 1206Y2K00102KXT, both manufactured by Knowles Syfer under the FlexiCap™ series, meet all critical electrical and mechanical parameters. Both substitutes maintain identical capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications as the primary part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CS1206KKX7RDBB102 (YAGEO), 1206Y2K00102KJT (Knowles Syfer), and 1206Y2K00102KXT (Knowles Syfer)—are Active status components with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts may be based on inventory availability and lead time requirements. The Knowles Syfer FlexiCap™ series parts (1206Y2K00102KJT and 1206Y2K00102KXT) offer higher inventory levels (6110 and 23197 units respectively) compared to the YAGEO CS series (3573 units). All parts are suitable for direct substitution in boardflex-sensitive applications requiring soft termination characteristics.

Frequently Asked Questions (FAQ)

Q: Can 1206Y2K00102KJT or 1206Y2K00102KXT be used as direct replacements for CS1206KKX7RDBB102?

A: Yes. Both Knowles Syfer parts meet all critical electrical specifications (1000 pF, ±10%, 2000V, X7R) and mechanical requirements (1206 package, soft termination, boardflex sensitivity). All compliance certifications (ROHS3, MSL 1, REACH Unaffected, EAR99) are identical.

Q: Are there dimensional differences between these parts?

A: The primary part CS1206KKX7RDBB102 has a maximum thickness of 0.057" (1.45mm), while both Knowles Syfer substitutes have a maximum thickness of 0.063" (1.60mm). Length and width dimensions remain identical at 0.126" L x 0.063" W (3.20mm x 1.60mm). This thickness variation is within standard 1206 package tolerances and does not affect electrical performance or PCB assembly compatibility.

Q: What determines substitution eligibility for this capacitor?

A: Substitution is based on exact matching of capacitance (1000 pF), tolerance (±10%), voltage rating (2000V), temperature coefficient (X7R), package type (1206), mounting method (surface mount MLCC), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, MSL 1). Any deviation in these parameters disqualifies a part from direct substitution.

Q: Are all three parts suitable for boardflex-sensitive applications?

A: Yes. All three parts feature soft termination and are rated for boardflex-sensitive applications, making them functionally equivalent for this use case.
