Substitute Part Grouping Explanation

Substitution for the 1812SC103MAT1A is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance value: 10000 pF (exact match required)
• Voltage rating: 1500V (1.5kV) minimum (equal or higher acceptable)
• Temperature coefficient: X7R (required for temperature stability)
• Package / Case: 1812 (4532 Metric) (exact match required for PCB compatibility)
• Physical dimensions: 0.181" L x 0.126" W x 0.110" max thickness (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)

Allowable Variations:

• Capacitance tolerance may vary (±10%, ±20%, or tighter tolerances are acceptable)
• Packaging format may differ (bulk, tape & reel, or other standard formats)
• Inventory availability and lead times may vary

The substitute part 1812SC103KAT1A meets all critical substitution criteria with identical electrical specifications except for improved capacitance tolerance (±10% versus ±20%), making it a direct equivalent for the 1812SC103MAT1A.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC103MAT1A and 1812SC103KAT1A are active production parts from KYOCERA AVX with identical compliance certifications. The 1812SC103KAT1A offers improved capacitance tolerance (±10% versus ±20%), which may provide tighter performance characteristics in applications requiring closer capacitance values. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements. Selection between these parts should be based on tolerance requirements for the specific application and packaging format availability (tape & reel versus other formats).

Frequently Asked Questions (FAQ)

Q: Can 1812SC103KAT1A replace 1812SC103MAT1A in my circuit?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance, voltage rating, temperature coefficient, and package dimensions. The substitute part features improved capacitance tolerance (±10% versus ±20%).

Q: What is the difference between these two parts?

A: The primary difference is capacitance tolerance. The 1812SC103MAT1A has ±20% tolerance, while the 1812SC103KAT1A has ±10% tolerance. Both parts are manufactured by KYOCERA AVX and share identical electrical ratings and physical dimensions.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1812 (4532 Metric) package with dimensions of 0.181" L x 0.126" W (4.60mm x 3.20mm) and maximum thickness of 0.110" (2.80mm). They are directly interchangeable on PCBs designed for this package size.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both the 1812SC103MAT1A and 1812SC103KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply.

Q: Can I use a higher voltage-rated part as a substitute?

A: Substitution is based on the specified parameters. Both parts are rated at 1500V (1.5kV). Parts with higher voltage ratings would not be considered equivalent substitutes for this specification.
