SR151C222MAT Equivalent & Substitute Parts

Part Overview

The SR151C222MAT is a 2200 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This through-hole radial component is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently in active production status with 855 units in stock.

Substitute parts are identified when equivalent electrical performance can be maintained while accommodating different tolerance specifications, packaging formats, or inventory availability constraints.

Substitute Part Grouping Explanation

The SR151C222KARTR2 qualifies as a direct substitute based on the following criteria:

Electrical Equivalence: Identical capacitance value (2200 pF), voltage rating (100V), and temperature coefficient (X7R) ensure functional compatibility in circuit applications.

Mechanical Compatibility: Matching lead spacing (0.100"), physical dimensions (0.150" L x 0.100" W), and radial through-hole mounting configuration allow direct board-level substitution without layout modifications.

Tolerance Consideration: The substitute part features ±10% tolerance compared to the original ±20% tolerance. This represents an upgrade in capacitance accuracy and does not restrict substitution in applications designed for the original tolerance specification.

Compliance Alignment: Both parts maintain ROHS3 compliance, identical operating temperature range, and equivalent regulatory status (REACH Unaffected, ECCN EAR99).

Packaging Difference: The substitute is supplied in Cut Tape (CT) format versus the original packaging specification, with significantly higher inventory availability (2506 units).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (SR151C222MAT): Use when original part number specification is required or when ±20% tolerance is explicitly called out in design documentation.

Substitute Selection (SR151C222KARTR2): Use when improved capacitance tolerance (±10%) is beneficial to circuit performance, when Cut Tape packaging is compatible with assembly processes, or when higher inventory availability is required to meet production schedules. Both parts maintain identical ROHS3 compliance and active production status, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can SR151C222KARTR2 be used as a direct replacement for SR151C222MAT?

A: Yes. Both parts share identical electrical specifications (2200 pF, 100V, X7R), mechanical dimensions, lead spacing, and mounting configuration. The substitute features improved tolerance (±10% versus ±20%), which does not restrict substitution in applications designed for the original part.

Q: What is the difference between the packaging formats?

A: SR151C222MAT is supplied in standard packaging, while SR151C222KARTR2 is supplied in Cut Tape (CT) format. Cut Tape packaging is compatible with automated pick-and-place assembly equipment and offers higher unit availability.

Q: Are both parts RoHS compliant?

A: Yes. Both SR151C222MAT and SR151C222KARTR2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the tolerance difference affect circuit performance?

A: The ±10% tolerance of SR151C222KARTR2 represents tighter capacitance control compared to the ±20% tolerance of SR151C222MAT. This upgrade does not negatively impact circuits designed for the original tolerance specification and may improve performance in applications sensitive to capacitance variation.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance across this full range.
