1812CC104MAT3A\SB Equivalent & Substitute Parts

Part Overview

The 1812CC104MAT3A\SB is a 0.1 µF ±20% 630V ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient in 1812 (4532 Metric) surface mount package. This component is classified as Active and maintains 760 pieces in current inventory. The part is ROHS3 compliant with MSL 1 rating, suitable for general purpose high voltage applications across the -55°C to 125°C operating temperature range.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting mechanical and compliance requirements for the 1812 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Capacitance: 0.1 µF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage Rating: 630V minimum (equal or higher voltage ratings are acceptable)
• Tolerance: ±20% or better (±10% tolerance represents improvement)
• Manufacturer: Different manufacturers permitted if all other parameters match

All substitute parts listed meet these criteria. Voltage ratings equal to or exceeding 630V maintain backward compatibility. Improved tolerance specifications (±10%) provide enhanced precision without compromising circuit function.

Parameter Comparison

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

1812CC104KAT1A (KYOCERA AVX) - Same manufacturer as primary part with improved ±10% tolerance and Active product status. Tape & Reel packaging supports automated assembly.

C1812C104KBRAC7800 (KEMET) - Active status with ±10% tolerance, Low ESL feature, and reduced thickness (1.55mm). Largest inventory availability (12,960 pcs) supports production volume requirements.

C1812C104KDRAC7800 (KEMET) - Active status with elevated 1000V rating providing additional voltage margin. ±10% tolerance and Low ESL characteristics. Suitable for applications requiring enhanced voltage headroom.

GRM43DR72J104KW01L (Murata Electronics) - Active status with ±10% tolerance and highest inventory level (107,400 pcs). GRM series provides established supply chain stability.

Legacy Status Parts (Not Recommended for New Designs):

C4532X7R2J104M230KA (TDK Corporation) - Marked "Not For New Designs" despite matching electrical specifications. Suitable only for replacement or legacy system maintenance.

SMK432B7104KM-T (Taiyo Yuden) - Marked "Not For New Designs" with ±10% tolerance. Inventory available (5,800 pcs) for legacy applications only.

All listed parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status consistent with the primary part specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute a part with ±10% tolerance for the original ±20% tolerance specification?

A: Yes. Improved tolerance (±10%) is a direct upgrade that maintains circuit compatibility while providing enhanced precision. The circuit design based on ±20% tolerance will function correctly with ±10% tolerance components.

Q: Are higher voltage rated parts (1000V vs 630V) suitable substitutes?

A: Yes. Higher voltage ratings provide additional safety margin and are electrically compatible. The C1812C104KDRAC7800 (1000V rating) operates within the same capacitance and temperature coefficient specifications while offering enhanced voltage headroom.

Q: What is the difference between packaging types (Tape & Reel vs Cut Tape)?

A: Both packaging types contain identical components. Tape & Reel (TR) supports continuous automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower volume or mixed component requirements. Selection depends on assembly process requirements, not electrical performance.

Q: Why are some parts marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development or production planning for that part number. While electrically equivalent and currently in stock, these parts should be used only for replacement or legacy system maintenance. Active status parts are recommended for new circuit designs to ensure long-term supply availability.

Q: Does physical size variation affect substitution compatibility?

A: All listed parts conform to the 1812 (4532 Metric) package specification. Minor dimensional variations in thickness (1.55mm to 2.70mm range) are within package tolerance and do not affect PCB assembly compatibility or electrical performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part's regulatory requirements.
