Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC272MAT3A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 2700 pF (no tolerance variation in nominal value)
• Voltage Rating: Must be 2000V (2kV) minimum
• Temperature Coefficient: Must be X7R
• Package Format: Must be 1812 (4532 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.181" L x 0.126" W (4.60mm x 3.20mm) and 0.071" (1.80mm) thickness
• Compliance: Must maintain RoHS3 compliance and REACH unaffected status

The identified substitute part 1812GC272KAT1A meets all electrical and mechanical equivalence criteria. The primary distinction is the tolerance specification: the substitute offers ±10% tolerance compared to the main part's ±20% tolerance, representing an upgrade in precision without altering functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812GC272MAT3A and 1812GC272KAT1A are Active product status components manufactured by KYOCERA AVX with identical electrical specifications and mechanical compatibility. Selection between these parts is based on the following engineering criteria:

1812GC272MAT3A is appropriate for applications where ±20% capacitance tolerance is acceptable and bulk packaging is preferred.

1812GC272KAT1A is appropriate for applications requiring tighter capacitance tolerance (±10%) and where Tape & Reel packaging format is required for automated assembly processes. This substitute provides enhanced precision without compromising electrical or mechanical compatibility.

Both components maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all applicable jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can 1812GC272KAT1A be used as a direct replacement for 1812GC272MAT3A?

A: Yes. Both parts are electrically and mechanically equivalent. The substitute offers improved tolerance specification (±10% versus ±20%) and is supplied in Tape & Reel packaging format instead of bulk packaging.

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

A: Tolerance defines the allowable deviation from the nominal 2700 pF capacitance value. The ±10% tolerance of the substitute part provides a tighter specification band, resulting in more precise capacitance values. This is an upgrade in component precision and does not create compatibility issues in applications designed for the ±20% tolerance part.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1812 (4532 Metric) package with identical dimensions: 0.181" L x 0.126" W (4.60mm x 3.20mm) and maximum thickness of 0.071" (1.80mm). They are mechanically interchangeable on PCBs designed for this package format.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly processes and high-volume production. The electrical and mechanical properties of the component are identical; only the delivery format differs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 1812GC272MAT3A and 1812GC272KAT1A are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). They meet identical regulatory and environmental requirements.
