1206AC472MAT1A Equivalent & Substitute Parts

Part Overview

The 1206AC472MAT1A 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 a wide operating temperature range of -55°C to 125°C. The part is currently active and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained while accommodating design flexibility, inventory availability, or manufacturing sourcing requirements. Substitution is valid only when all critical electrical and mechanical parameters remain within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity is determined by strict adherence to the following parameters:

• Capacitance: Must be 4700 pF (no deviation)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 1206 (3216 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must encompass -55°C to 125°C
• RoHS Status: Must be ROHS3 Compliant
• Moisture Sensitivity Level: Must be MSL 1 or better

The main part 1206AC472MAT1A carries a tolerance of ±20%. Substitute parts with ±10% tolerance represent improved tolerance specifications and are electrically compatible. All identified substitutes maintain identical capacitance, voltage rating, temperature coefficient, package dimensions, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts meet the electrical and mechanical requirements for direct replacement of 1206AC472MAT1A. Selection criteria are based on product status, compliance certifications, and inventory availability:

KYOCERA AVX 1206AC472KAT1A: Same manufacturer as the main part with improved ±10% tolerance specification. Product status is active with 3302 units in stock. Recommended for designs requiring tighter capacitance tolerance while maintaining manufacturer consistency.

KYOCERA AVX KGM31AR73A472KU: Belongs to the KGM - HV series from KYOCERA AVX with ±10% tolerance. Product status is active with 5942 units in stock. Suitable for high-voltage applications with enhanced inventory availability.

YAGEO CC1206KKX7RCBB472: Alternative manufacturer from YAGEO with ±10% tolerance specification. Product status is active with 9100 units in stock. Provides cross-manufacturer sourcing flexibility with highest inventory level among KYOCERA AVX alternatives.

Johanson Dielectrics Inc. VPDD102W472K1GV001E: Part of the HVS-PME series with ±10% tolerance and application focus on SMPS filtering. Product status is active with 262651 units in stock. Offers maximum inventory availability and specialized high-voltage filtering application support.

All substitute parts carry ROHS3 compliance, MSL 1 rating, and identical operating temperature range. Physical dimensions remain compatible with 1206 (3216 Metric) footprint requirements.

Frequently Asked Questions (FAQ)

Q: Can 1206AC472KAT1A replace 1206AC472MAT1A directly?

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 substitute has improved ±10% tolerance compared to the main part's ±20% tolerance, making it electrically compatible and functionally superior for tolerance-sensitive applications.

Q: What is the difference between KYOCERA AVX and YAGEO substitutes?

A: Both manufacturers provide equivalent electrical specifications: 4700 pF, 1000V, X7R, 1206 package, and -55°C to 125°C operating range. The primary difference is manufacturer sourcing. YAGEO CC1206KKX7RCBB472 offers higher inventory availability (9100 units) compared to KYOCERA AVX alternatives, providing supply chain flexibility.

Q: Are physical dimensions identical across all substitute parts?

A: All parts conform to the 1206 (3216 Metric) package standard. Minor dimensional variations exist within manufacturing tolerances: length ranges from 0.125" to 0.130" (3.18mm to 3.30mm), width is 0.062" to 0.063" (1.57mm to 1.60mm), and thickness ranges from 0.057" to 0.071" (1.45mm to 1.80mm). These variations remain within standard PCB footprint design margins for 1206 components.

Q: Why do substitute parts have ±10% tolerance instead of ±20%?

A: Tolerance specification is a manufacturing and quality parameter independent of substitution validity. The ±10% tolerance on substitute parts represents tighter capacitance control during manufacturing. Both ±20% and ±10% tolerances are acceptable for the same electrical function; ±10% simply provides higher precision.

Q: Is Johanson Dielectrics VPDD102W472K1GV001E suitable for general-purpose applications?

A: Yes. While the part is designated for SMPS filtering applications, it meets all electrical and mechanical requirements for general-purpose use. The 4700 pF capacitance, 1000V rating, X7R temperature coefficient, and 1206 package make it functionally equivalent to the main part across all application categories.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Handling, storage, and assembly processes are identical across all identified substitutes.
