1206J2000271GCT Equivalent & Substitute Parts

Part Overview

The 1206J2000271GCT is a 270 pF ceramic capacitor manufactured by Knowles Syfer, rated at 200V with C0G/NP0 temperature coefficient and ±2% tolerance. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit higher voltage ratings.

Substitute Part Grouping Explanation

Substitute parts for the 1206J2000271GCT are qualified based on the following electrical and mechanical parameters:

• Capacitance value: 270 pF (exact match required)
• Tolerance: ±2% (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The identified substitute parts meet all these criteria. The voltage rating of substitute parts exceeds the original specification (500V vs. 200V), which is permissible in applications where the circuit design allows higher voltage-rated components. Physical dimensions remain compatible with the 1206 package footprint.

Parameter Comparison

Engineering Selection Recommendations

All three parts—the primary 1206J2000271GCT and the two substitute options C1206C271GCGAC7800 and KGM31VCG2H271GU—maintain active product status and full ROHS3 compliance. Selection between these parts should be based on availability, packaging preference, and physical space constraints.

The KEMET C1206C271GCGAC7800 offers the lowest maximum thickness at 0.043" (1.10mm), making it suitable for space-constrained applications. The KYOCERA AVX KGM31VCG2H271GU provides the highest inventory availability at 11,528 pieces and is supplied in Tape & Reel packaging. The original Knowles Syfer part maintains the lowest voltage rating at 200V, appropriate for circuits designed to that specification.

All parts share identical electrical characteristics: 270 pF capacitance, ±2% tolerance, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. The substitute parts' higher voltage ratings (500V) do not compromise performance in applications rated for 200V operation.

Frequently Asked Questions (FAQ)

Q: Can the KEMET C1206C271GCGAC7800 or KYOCERA AVX KGM31VCG2H271GU be used as direct replacements for the Knowles Syfer 1206J2000271GCT?

A: Yes. Both substitute parts meet all electrical and mechanical specifications. The 1206 package footprint is identical across all three parts. The higher voltage ratings of the substitute parts (500V vs. 200V) are compatible with circuits designed for 200V operation.

Q: What is the significance of the C0G/NP0 temperature coefficient designation?

A: C0G and NP0 are equivalent designations indicating zero temperature coefficient. This means the capacitance value remains stable across the operating temperature range of -55°C to 125°C, with negligible drift. All three parts share this characteristic.

Q: Are there physical space differences between these parts?

A: Yes. While all parts use the 1206 (3216 Metric) package with identical length and width (3.20mm x 1.60mm), thickness varies: the Knowles Syfer part is 1.60mm thick, the KEMET part is 1.10mm thick, and the KYOCERA AVX part is 1.22mm thick. For applications with height constraints, the KEMET option provides the smallest profile.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts share this classification.

Q: Are all parts ROHS3 compliant?

A: Yes. The 1206J2000271GCT, C1206C271GCGAC7800, and KGM31VCG2H271GU are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
