SR155C222MAT Equivalent & Substitute Parts

Part Overview

The SR155C222MAT is a 2200 pF ceramic capacitor rated at 50V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently in active production status with 1047 units in stock.

Substitute parts are identified when electrical parameters remain compatible with circuit requirements while offering improvements in tolerance, voltage rating, or packaging options. Alternative sources ensure design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR155C222MAT is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 2200 pF (exact match required)
• Temperature coefficient: X7R (ensures equivalent temperature stability)
• Mounting type: Through Hole (maintains PCB assembly compatibility)
• Package type: Radial (preserves lead configuration and spacing)
• Lead spacing: 0.100" (2.54mm) (ensures footprint compatibility)
• Physical dimensions: 0.150" L x 0.100" W (3.81mm x 2.54mm) (maintains board layout compatibility)

Allowable Variations:

• Voltage rating: May be equal to or greater than 50V (higher ratings provide additional design margin)
• Tolerance: May be tighter than ±20% (improved tolerance provides better circuit performance)
• Packaging format: May differ (Bulk, Cut Tape) without affecting electrical function

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

SR155C222KAR Selection Criteria: This substitute maintains identical electrical specifications to the SR155C222MAT with the exception of improved tolerance (±10% versus ±20%). Both parts are rated at 50V and share all mechanical and thermal characteristics. Selection of SR155C222KAR is appropriate when tighter capacitance tolerance is required for circuit performance. Both parts carry ROHS3 compliance and active product status. Packaging is available in Bulk format with 1295 units in stock.

SR151C222KARTR2 Selection Criteria: This substitute provides a higher voltage rating of 100V while maintaining the 2200 pF capacitance and ±10% tolerance. The elevated voltage rating provides additional design margin in applications where the 50V rating of the main part may approach circuit stress limits. This part is also ROHS3 compliant with active product status. Packaging is available in Cut Tape (CT) format with 2506 units in stock, supporting automated assembly processes.

All three parts are manufactured by KYOCERA AVX within the SkyCap® SR series and maintain identical physical dimensions and lead spacing, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can SR155C222KAR be used as a direct replacement for SR155C222MAT? A: Yes. Both parts have identical capacitance (2200 pF), voltage rating (50V), temperature coefficient (X7R), physical dimensions, and lead spacing. SR155C222KAR offers improved tolerance (±10% versus ±20%), making it functionally equivalent with enhanced precision.

Q: What is the primary difference between SR155C222KAR and SR151C222KARTR2? A: The voltage rating differs. SR155C222KAR is rated at 50V, while SR151C222KARTR2 is rated at 100V. Both maintain 2200 pF capacitance and ±10% tolerance. The higher voltage rating of SR151C222KARTR2 provides additional design margin but does not affect physical compatibility.

Q: Are all three parts mechanically interchangeable? A: Yes. All three parts share identical physical dimensions (0.150" L x 0.100" W), lead spacing (0.100"), and radial package configuration. They mount directly to the same PCB footprint without modification.

Q: What packaging formats are available? A: SR155C222MAT and SR155C222KAR are supplied in Bulk packaging. SR151C222KARTR2 is supplied in Cut Tape (CT) format, suitable for automated pick-and-place assembly.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All maintain active product status with current manufacturing support.

Q: Which substitute should be selected for improved circuit performance? A: Selection depends on circuit requirements. For tighter capacitance tolerance, SR155C222KAR provides ±10% accuracy. For applications requiring higher voltage margin, SR151C222KARTR2 at 100V rating is appropriate. Both are electrically and mechanically compatible with the original SR155C222MAT design.
