1812HC102MAT1A Equivalent & Substitute Parts

Part Overview

The 1812HC102MAT1A is a 1000 pF ceramic capacitor rated for 3000V (3kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) package format. 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 in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and performance upgrades where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812HC102MAT1A is determined by the following critical parameters: capacitance value (1000 pF), voltage rating (3000V minimum), temperature coefficient (X7R), package format (1812/4532 Metric), and mounting type (Surface Mount MLCC). All identified substitutes maintain these core electrical and mechanical specifications.

Substitutes are categorized as follows:

Direct Manufacturer Equivalents maintain identical electrical specifications and packaging format, differing only in tolerance or series designation. These parts are interchangeable without circuit redesign.

Upgrade Parts offer improved tolerance (±10% versus ±20%) while maintaining all other electrical and mechanical parameters. These parts provide enhanced capacitance stability and are suitable for applications requiring tighter component specifications.

Parametric Equivalents match all electrical specifications and package dimensions but differ in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). These parts are electrically and mechanically compatible but may require different handling procedures.

Cross-Manufacturer Alternatives from different manufacturers (KEMET) meet identical electrical specifications and package requirements, providing supply chain flexibility while maintaining performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 1812HC102MAT1A specification.

For direct replacement without circuit modification: Select KGM43FR73U102MV, which maintains identical electrical specifications, tolerance, and package dimensions. This part is suitable for applications where the original part number is unavailable.

For improved capacitance stability: Select either 1812HC102KAT1A or KGM43FR73U102KV, both offering ±10% tolerance versus the original ±20%. These upgrades are appropriate for circuits requiring tighter capacitance control while maintaining all other electrical and mechanical parameters.

For alternative packaging format: Select 1812HC102MAT1A in Cut Tape & Digi-Reel® format when tape-and-reel packaging is not required, or C1812C102KHRAC7800 from KEMET for cross-manufacturer supply chain diversification.

For compact form factor with cross-manufacturer option: Select C1812C102KHRAC7800 (KEMET), which provides ±10% tolerance, reduced thickness (1.80mm versus 2.20mm), and lower ESL characteristics while maintaining 3000V rating and X7R temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can KGM43FR73U102MV be used as a direct replacement for 1812HC102MAT1A?

A: Yes. Both parts share identical capacitance (1000 pF), tolerance (±20%), voltage rating (3000V), temperature coefficient (X7R), and package format (1812/4532 Metric). The thickness difference of 0.01mm (2.21mm versus 2.20mm) is within standard manufacturing tolerances and does not affect mechanical compatibility.

Q: What is the advantage of selecting 1812HC102KAT1A or KGM43FR73U102KV over the original part?

A: These parts offer ±10% capacitance tolerance compared to the original ±20% tolerance. This tighter tolerance specification provides improved capacitance stability and is suitable for applications requiring more precise component values. All other electrical and mechanical parameters remain identical.

Q: Are KEMET C1812C102KHRAC7800 and KYOCERA AVX parts electrically equivalent?

A: Yes. The KEMET part maintains the same capacitance (1000 pF), voltage rating (3000V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The KEMET part offers ±10% tolerance and features lower ESL. Physical dimensions differ slightly (4.50mm length versus 4.60mm, and 1.80mm thickness versus 2.20mm), but both conform to 1812 (4532 Metric) package specifications.

Q: Does packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly procedures. Electrical performance and mechanical compatibility remain identical regardless of packaging format.

Q: Which substitute part offers the best inventory availability?

A: KGM43FR73U102KV provides the highest inventory level at 3091 pieces, followed by 1812HC102KAT1A at 2400 pieces. Both are upgrade parts with ±10% tolerance.
