1206J2000271KAT Equivalent & Substitute Parts

Part Overview

The 1206J2000271KAT is a 270 pF ceramic capacitor manufactured by Knowles Syfer, rated at 200V with C0G/NP0 temperature coefficient in 1206 (3216 Metric) surface mount package. This component is currently active in production and widely used in automotive applications requiring stable capacitance across temperature ranges from -55°C to 125°C.

Substitute parts become necessary when the original manufacturer experiences supply constraints, discontinuation, or when design requirements allow for higher voltage ratings or improved tolerance specifications. The parts listed below maintain electrical and mechanical compatibility while offering alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1206J2000271KAT is determined by the following mandatory parameters:

• Capacitance value: 270 pF (exact match required)
• Package type: 1206 (3216 Metric) surface mount (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Voltage rating: 200V minimum (equal or higher acceptable)
• Tolerance: ±10% or better (tighter tolerance acceptable)
• Compliance: AEC-Q200, ROHS3, MSL 1

The substitute parts listed below meet all mandatory parameters. Voltage ratings exceed the original specification, providing design margin. Tolerance specifications are equal or superior to the original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the 1206J2000271KAT. Selection should be based on the following factors:

C1206C271JBGACAUTO (KEMET): This part is currently in active production status with 2384 units in stock. It offers improved tolerance (±5% versus ±10%) and higher voltage rating (630V versus 200V). The Tape & Reel packaging matches the original part format. This part is suitable for immediate procurement and long-term supply continuity.

CGA5C4C0G2J271J060AA (TDK Corporation): This part carries Last Time Buy status, indicating limited future availability. While it meets all electrical specifications with ±5% tolerance and 630V rating, procurement should be evaluated against long-term supply requirements. Cut Tape packaging differs from the original Tape & Reel format and may require adjustment to assembly processes.

Frequently Asked Questions (FAQ)

Q: Can C1206C271JBGACAUTO replace 1206J2000271KAT directly?

A: Yes. Both parts share identical capacitance (270 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 1206 package dimensions. The KEMET part provides higher voltage rating (630V) and tighter tolerance (±5%), making it electrically and mechanically compatible.

Q: What is the difference between the two substitute parts?

A: Both substitute parts meet the electrical requirements. The primary differences are manufacturer, product status, and packaging format. KEMET's C1206C271JBGACAUTO is in active production with Tape & Reel packaging. TDK's CGA5C4C0G2J271J060AA is Last Time Buy status with Cut Tape packaging.

Q: Does the higher voltage rating (630V) affect circuit performance?

A: No. Higher voltage rating does not degrade performance in circuits designed for 200V operation. The capacitance value, tolerance, and temperature coefficient remain the same. Higher voltage rating provides additional design margin and reliability.

Q: Are there any package dimension differences?

A: All three parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). Thickness varies slightly: original 0.063" (1.60mm), KEMET 0.069" (1.75mm), and TDK 0.030" (0.75mm). These variations remain within standard PCB assembly tolerances.

Q: What is the significance of AEC-Q200 rating?

A: AEC-Q200 certification confirms the part meets automotive-grade reliability standards for passive components. All three parts carry this certification, ensuring suitability for automotive applications.

Q: Does MSL 1 rating affect handling and storage?

A: MSL 1 (Unlimited) indicates no moisture sensitivity. All three parts can be stored and handled without special moisture control measures, simplifying inventory management and assembly processes.
