Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC272MAT1A is determined by the following critical parameters:

• Capacitance Value: 2700 pF (exact match required)
• Voltage Rating: 2000V (2kV) minimum (equal or higher acceptable)
• Temperature Coefficient: X7R (required for temperature stability)
• Package / Case: 1812 (4532 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical Dimensions: 0.181" L x 0.126" W, 0.071" max thickness (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part 1812GC272KAT1A meets all critical parameters with an improved tolerance specification (±10% versus ±20%), making it functionally equivalent and directly interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812GC272MAT1A and 1812GC272KAT1A are Active products manufactured by KYOCERA AVX with identical electrical ratings, temperature performance, and physical form factors. The substitute part 1812GC272KAT1A offers improved capacitance tolerance (±10% versus ±20%), providing tighter value control for precision circuit applications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on tolerance requirements and packaging availability (Tape & Reel for the substitute).

Frequently Asked Questions (FAQ)

Q: Can 1812GC272KAT1A replace 1812GC272MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (2700 pF), voltage rating (2000V), temperature coefficient (X7R), package (1812), and physical dimensions. The substitute offers improved tolerance specification.

Q: What is the significance of the tolerance difference (±20% vs ±10%)?

A: Tolerance defines the acceptable deviation from the nominal capacitance value. The ±10% tolerance of 1812GC272KAT1A provides tighter capacitance control, beneficial for circuits requiring precise capacitive values. The ±20% tolerance of 1812GC272MAT1A is acceptable for general-purpose applications with wider tolerance margins.

Q: Are there packaging differences between these parts?

A: The main part 1812GC272MAT1A uses standard packaging, while the substitute 1812GC272KAT1A is supplied in Tape & Reel (TR) format. Both are surface mount components with identical footprints and mounting requirements.

Q: Do both parts meet current compliance standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions (1812 / 4532 Metric), mounting type (Surface Mount, MLCC), and electrical ratings ensure direct PCB footprint compatibility and functional interchangeability.
