Equivalent & Substitute Parts for 1812CC103MAT3A\SB

Part Overview

The 1812CC103MAT3A\SB is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 630V with X7R temperature coefficient and 1812 (4532 Metric) package form factor. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified to address application requirements for higher voltage ratings, improved tolerance specifications, or alternative manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812CC103MAT3A\SB are qualified based on the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 10000 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Voltage Rating: Equal to or greater than 630V
• Operating Temperature Range: -55°C to 125°C (exact match required)

Mechanical Parameters (Must Match or Be Compatible):

• Package / Case: 1812 (4532 Metric) form factor
• Mounting Type: Surface Mount, MLCC
• Physical dimensions compatible with 1812 footprint

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

All substitute parts maintain identical capacitance, temperature coefficient, and operating temperature specifications. Voltage ratings in substitute parts are rated at 1000V (1kV), providing increased voltage margin over the original 630V specification. Tolerance specifications vary between ±10% and ±20% across substitute options.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring continued regulatory compliance and long-term component availability. The three substitute options provide voltage ratings of 1000V (1kV), exceeding the original 630V specification and offering increased design margin for high-voltage applications.

1812AC103KAT1A (KYOCERA AVX): Offers ±10% tolerance with 1000V rating. Thickness specification is 0.087" (2.20mm), compatible with 1812 footprint requirements. Tape & Reel packaging available with 2540 units in stock.

KGM43FR73A103MV (KYOCERA AVX, KGM - HV Series): Maintains ±20% tolerance matching the original part, with 1000V rating. Thickness specification is 0.087" (2.21mm). Tape & Reel packaging available with 2712 units in stock.

C4532X7R3A103K200KA (TDK Corporation): Provides ±10% tolerance with 1000V rating. Physical dimensions are 0.177" L x 0.126" W (4.50mm x 3.20mm) with 0.087" (2.20mm) thickness, compatible with 1812 footprint. Tape & Reel packaging available with 86839 units in stock.

Frequently Asked Questions (FAQ)

Q: Can I use a 1000V rated capacitor in place of a 630V rated capacitor?

A: Yes. The substitute parts rated at 1000V (1kV) are electrically compatible with applications designed for 630V operation. Higher voltage ratings provide increased safety margin and do not degrade performance in lower-voltage applications.

Q: What is the difference between ±10% and ±20% tolerance specifications?

A: Tolerance defines the allowable deviation from the nominal 10000 pF capacitance value. ±10% tolerance allows deviation between 9000 pF and 11000 pF, while ±20% tolerance allows deviation between 8000 pF and 12000 pF. Applications requiring tighter capacitance control should select ±10% tolerance options.

Q: Are all substitute parts mechanically compatible with the 1812 footprint?

A: Yes. All substitute parts use the 1812 (4532 Metric) package form factor with compatible physical dimensions and Surface Mount, MLCC mounting type. Thickness variations (0.087" to 0.071") remain within standard 1812 package specifications.

Q: Can I substitute between KYOCERA AVX and TDK Corporation parts?

A: Yes. The TDK Corporation part C4532X7R3A103K200KA maintains identical electrical specifications, package form factor, and compliance certifications, making it a direct substitute for KYOCERA AVX parts in this application.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, requiring no special moisture control during storage, handling, or assembly. These components can be stored and used without desiccant packaging or time-limited shelf life restrictions.
