1812HC471MATME Equivalent & Substitute Parts

Part Overview

The 1812HC471MATME is a 470 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 3000V (3kV) operation with X7R temperature coefficient characteristics. This Surface Mount MLCC (Multilayer Ceramic Capacitor) in 1812 (4532 Metric) package format is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching core electrical specifications and mechanical compatibility within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812HC471MATME is determined by the following mandatory parameters:

• Capacitance value: 470 pF (exact match required)
• Voltage rating: 3000V (3kV) minimum
• Temperature coefficient: X7R (ensures stable performance across -55°C to 125°C)
• Package format: 1812 (4532 Metric) surface mount
• Physical dimensions: 0.181" L × 0.126" W, maximum thickness 0.071"
• Mounting type: Surface Mount MLCC
• Compliance: ROHS3 and REACH requirements

The identified substitute parts 1812HC471KAT1A and KGM43ER73U471KV meet all mandatory electrical and mechanical parameters. Both parts are manufactured by KYOCERA AVX, maintain identical capacitance, voltage rating, temperature coefficient, and package specifications. Tolerance variations (±10% versus ±20%) and packaging format differences (Tape & Reel) represent upgrades in precision and handling convenience without affecting core substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1812HC471MATME, 1812HC471KAT1A, and KGM43ER73U471KV—are active production components from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

The 1812HC471MATME with ±20% tolerance is suitable for general-purpose high-voltage applications where capacitance variation within this range is acceptable. The 1812HC471KAT1A and KGM43ER73U471KV both offer improved tolerance specification at ±10%, providing tighter capacitance control for circuits requiring greater precision. Both substitute parts are supplied in Tape & Reel packaging, which is standard for automated assembly processes.

The KGM43ER73U471KV is designated as part of the KGM - HV series, indicating specialized high-voltage design optimization. All parts maintain identical physical footprint compatibility and thermal performance characteristics across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 1812HC471KAT1A directly replace 1812HC471MATME in existing designs?

A: Yes. Both parts share identical capacitance (470 pF), voltage rating (3kV), temperature coefficient (X7R), package format (1812), and physical dimensions. The primary difference is improved tolerance specification (±10% versus ±20%), which represents an upgrade in precision without affecting mechanical or electrical compatibility.

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

A: The ±10% tolerance in 1812HC471KAT1A and KGM43ER73U471KV provides tighter capacitance control compared to the ±20% specification of 1812HC471MATME. This is beneficial for applications requiring more precise capacitance values, though both tolerance levels remain within the X7R temperature coefficient stability range across -55°C to 125°C.

Q: Are there packaging differences between these parts?

A: The 1812HC471MATME is available in standard packaging, while 1812HC471KAT1A and KGM43ER73U471KV are supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly processes. Both packaging formats contain identical components with the same electrical specifications.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. They are all active production components suitable for current design implementations.

Q: Is the KGM43ER73U471KV series designation significant for substitution?

A: The KGM - HV series designation indicates high-voltage optimization within the KYOCERA AVX product line. This does not affect substitution compatibility; it reflects the manufacturer's design focus for this particular part variant. All electrical and mechanical parameters remain equivalent to the other substitute options.
