1206AC472MAT9A Equivalent & Substitute Parts

Part Overview

The 1206AC472MAT9A is a 4700 pF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage 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 and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1206AC472MAT9A is determined by strict equivalence in the following parameters:

• Capacitance value: 4700 pF (exact match required)
• Voltage rating: 1000V (1kV) minimum
• Temperature coefficient: X7R (ensures stable performance across operating range)
• Package: 1206 (3216 Metric) form factor
• Mounting type: Surface Mount, MLCC
• Compliance: ROHS3 and REACH status

The primary distinction among substitute parts is tolerance specification. The main part 1206AC472MAT9A carries ±20% tolerance, while all identified substitutes feature ±10% tolerance, representing improved capacitance accuracy. Physical dimensions remain within acceptable ranges for the 1206 package classification.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection among substitutes should be based on the following factors:

1206AC472KAT1A and KGM31AR73A472KU are both KYOCERA AVX products with ±10% tolerance improvement over the main part. KGM31AR73A472KU belongs to the KGM - HV series, specifically designed for high-voltage applications. Both are available in Tape & Reel packaging.

VPDD102W472K1GV001E is manufactured by Johanson Dielectrics Inc. and belongs to the HVS-PME series. This part exhibits slightly reduced physical dimensions (0.125" x 0.062" length and width, 0.067" maximum thickness) compared to the KYOCERA AVX alternatives, while maintaining full 1206 package classification compatibility. This part is specified for SMPS filtering applications and offers the highest inventory availability among all substitutes.

All substitute parts are electrically and mechanically compatible with the original 1206AC472MAT9A specification.

Frequently Asked Questions (FAQ)

Q: Can 1206AC472KAT1A directly replace 1206AC472MAT9A?

A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (1000V), temperature coefficient (X7R), package (1206), and operating temperature range (-55°C to 125°C). The primary difference is improved tolerance (±10% versus ±20%), which represents a specification upgrade.

Q: What is the significance of the ±10% tolerance in substitute parts?

A: The ±10% tolerance specification in substitute parts provides tighter capacitance accuracy compared to the ±20% tolerance of the main part. This allows for more precise circuit performance in applications where capacitance variation impacts circuit behavior.

Q: Is VPDD102W472K1GV001E mechanically compatible with the 1206AC472MAT9A footprint?

A: Yes. Although VPDD102W472K1GV001E exhibits slightly smaller physical dimensions (0.125" x 0.062" versus 0.130" x 0.063"), it remains classified as a 1206 (3216 Metric) package and is compatible with standard 1206 PCB footprints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory requirements of the original part.

Q: Which substitute part has the highest inventory availability?

A: VPDD102W472K1GV001E from Johanson Dielectrics Inc. has the highest inventory level at 262,651 pieces in stock.

Q: Can I use KGM31AR73A472KU in place of 1206AC472MAT9A?

A: Yes. KGM31AR73A472KU is a direct electrical and mechanical substitute. It is part of the KGM - HV series specifically engineered for high-voltage applications and offers ±10% tolerance with identical voltage and capacitance specifications.
