1206GC471MAT1A Equivalent & Substitute Parts

Part Overview

The 1206GC471MAT1A is a 470 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 2000V (2kV) operation with X7R temperature coefficient and ±20% tolerance. This component is designed for general-purpose high-voltage applications requiring surface-mount multilayer ceramic capacitor (MLCC) technology in the 1206 (3216 Metric) package format. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching or superior electrical specifications, identical mechanical packaging, and compatible operating characteristics. Substitutes may offer improved tolerance grades (±10% vs ±20%) or alternative temperature coefficients (X7S vs X7R) while maintaining functional equivalence in circuit applications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among equivalent parts should be based on the following engineering considerations:

Same Manufacturer (KYOCERA AVX): 1206GC471KAT1A and KGM31AR73D471KU offer direct compatibility with existing supply chains and design validation. Both provide ±10% tolerance improvement over the original part specification.

Cross-Manufacturer Equivalents: C1206C471MGRAC7800 (KEMET), CC1206KKX7RDBB471 (YAGEO), VPDD202W471K1GV001E (Johanson Dielectrics), and C3216X7S3D471K130AA (TDK) are functionally equivalent with identical electrical ratings. Physical dimensions vary slightly within the 1206 footprint tolerance, with all parts maintaining compatibility with standard 1206 PCB layouts.

Temperature Coefficient Consideration: C3216X7S3D471K130AA uses X7S temperature coefficient instead of X7R. Both coefficients are acceptable for general-purpose applications within the -55°C to 125°C operating range. X7S provides slightly tighter capacitance stability across temperature extremes compared to X7R.

Tolerance Grade: Parts with ±10% tolerance (1206GC471KAT1A, KGM31AR73D471KU, CC1206KKX7RDBB471, VPDD202W471K1GV001E, C3216X7S3D471K130AA) are suitable direct replacements for the ±20% original part and offer improved circuit performance in applications requiring tighter capacitance accuracy.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 1206GC471MAT1A with a part having ±10% tolerance? A: Yes. Parts with ±10% tolerance (1206GC471KAT1A, KGM31AR73D471KU, CC1206KKX7RDBB471, VPDD202W471K1GV001E, C3216X7S3D471K130AA) are direct functional upgrades. The tighter tolerance provides improved capacitance accuracy without affecting circuit compatibility.

Q: What is the difference between X7R and X7S temperature coefficients? A: Both X7R and X7S are Class II ceramic dielectric materials suitable for general-purpose applications. X7S provides slightly tighter capacitance stability across the full -55°C to 125°C temperature range. Both maintain the same voltage rating and operating temperature limits for this 470 pF 2kV application.

Q: Are there physical dimension differences between substitute parts? A: Minor variations exist within the 1206 (3216 Metric) package specification. All listed parts are compatible with standard 1206 PCB footprints. Thickness ranges from 0.057" to 0.071" (1.45mm to 1.80mm), and length/width dimensions vary within ±0.004" (±0.10mm). These variations are within normal manufacturing tolerances and do not affect PCB assembly compatibility.

Q: Which substitute part has the highest inventory availability? A: C3216X7S3D471K130AA (TDK Corporation) has the highest reported inventory at 121,876 pieces. 1206GC471KAT1A (KYOCERA AVX) has 148,400 pieces available. Both parts offer excellent supply continuity for production applications.

Q: Can I use these parts interchangeably in existing designs? A: Yes, all listed substitute parts are electrically and mechanically compatible with the original 1206GC471MAT1A specification. No circuit redesign or PCB layout modification is required. Verify component placement clearances if switching between parts with different maximum thickness values (0.057" to 0.071").

Q: What compliance certifications apply to all substitute parts? A: All parts listed are ROHS3 compliant and REACH unaffected. All carry MSL 1 (unlimited) moisture sensitivity rating, indicating no special storage or handling requirements beyond standard component handling practices.
