1206J2000331GCT Equivalent & Substitute Parts

Part Overview

The 1206J2000331GCT is a 330 pF ceramic capacitor manufactured by Knowles Syfer, rated for 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 the operating temperature range of -55°C to 125°C. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 1206J2000331GCT is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 pF (exact match required)
• Voltage Rating: 200V (minimum acceptable rating)
• Temperature Coefficient: C0G/NP0 (ensures stable capacitance across temperature range)
• Package / Case: 1206 (3216 Metric) (ensures mechanical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (maintains assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (functional equivalence)
• Compliance: RoHS3 and REACH status (regulatory equivalence)

The substitute part KGM31BCG2D331FT from KYOCERA AVX meets all critical substitution criteria. While the substitute exhibits improved tolerance (±1% versus ±2%) and reduced thickness (0.037" versus 0.063"), these represent enhancements that do not compromise compatibility or introduce design risk.

Parameter Comparison

Engineering Selection Recommendations

Both the 1206J2000331GCT and KGM31BCG2D331FT are active production parts with full regulatory compliance. Selection between these parts is based on availability and design requirements:

The 1206J2000331GCT (Knowles Syfer) is the primary specification. Current inventory of 895 units supports immediate procurement.

The KGM31BCG2D331FT (KYOCERA AVX) is a direct substitute with enhanced specifications. The tighter tolerance (±1%) and reduced thickness (0.037" maximum) provide design margin without introducing compatibility concerns. Current inventory of 3855 units supports high-volume requirements and extended lead time mitigation.

Both parts satisfy identical electrical performance requirements, mechanical fit, and regulatory obligations. Selection may be driven by supply chain strategy, cost analysis, or design optimization preferences.

Frequently Asked Questions (FAQ)

Q: Can KGM31BCG2D331FT replace 1206J2000331GCT in existing designs?

A: Yes. Both parts are 1206 (3216 Metric) surface mount MLCCs with identical capacitance (330 pF), voltage rating (200V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). Mechanical footprint compatibility is confirmed. No design changes are required.

Q: What is the significance of the tolerance difference (±2% versus ±1%)?

A: The substitute part exhibits tighter tolerance, which represents improved capacitance accuracy. This does not create compatibility issues; it provides additional design margin. Applications requiring the original ±2% tolerance specification will continue to function within acceptable parameters with the ±1% substitute.

Q: Does the reduced thickness of KGM31BCG2D331FT affect assembly or performance?

A: No. The reduced thickness (0.037" versus 0.063" maximum) is a manufacturing improvement that does not affect electrical performance or assembly compatibility. The part maintains the same 1206 package footprint and mounting requirements.

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both 1206J2000331GCT and KGM31BCG2D331FT are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the moisture sensitivity rating for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.
