SR211C222MAT Equivalent & Substitute Parts

Part Overview

The SR211C222MAT is a 2200 pF ceramic capacitor rated at 100V 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 689 units in stock.

Substitute parts become necessary when design requirements change, such as increased voltage ratings for circuit protection, improved tolerance specifications for precision applications, or when primary part availability is constrained. The substitute parts listed maintain the core 2200 pF capacitance and X7R temperature coefficient while offering variations in voltage rating and tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR211C222MAT is determined by the following criteria:

Core Requirements (Non-Negotiable):

• Capacitance: 2200 pF (exact match)
• Temperature Coefficient: X7R (exact match)
• Mounting Type: Through Hole (exact match)
• Package Type: Radial (exact match)
• Lead Spacing: 0.200" (5.08mm) (exact match)
• Operating Temperature Range: -55°C to 125°C (exact match)
• RoHS Status: ROHS3 Compliant (exact match)

Allowable Variations:

• Voltage Rating: May be equal to or greater than 100V
• Tolerance: May be equal to or tighter than ±20%
• Physical Dimensions: Minor variations permitted within radial package constraints
• Manufacturer: Different manufacturers acceptable if all core requirements met

All substitute parts listed meet these criteria. Voltage ratings range from 100V to 1000V, and tolerance specifications range from ±10% to ±20%.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are ROHS3 compliant and maintain active production status, ensuring long-term availability and regulatory compliance equivalent to the SR211C222MAT.

Direct Voltage-Matched Substitutes (100V Rating): The C317C222K1R5TA from KEMET provides an exact voltage match at 100V while offering improved tolerance (±10% versus ±20%). This part is suitable for applications where the original tolerance specification is acceptable and no voltage margin is required.

Elevated Voltage Substitutes (200V Rating): The C317C222K2R5TA and C322C222K2R5TA from KEMET both provide 200V ratings with ±10% tolerance. These parts are appropriate for designs requiring additional voltage margin or for circuits operating at higher potential. The C322C222K2R5TA maintains the same physical footprint as the SR211C222MAT (0.200" L x 0.125" W), while the C317C222K2R5TA uses a smaller footprint (0.150" L x 0.100" W).

High-Voltage Substitutes (630V and 1000V Ratings): The Murata Electronics RDER series parts (RDER72J222K2M1H03A at 630V and RDER73A222K2K1H03B or RDER73A222K2M1H03A at 1000V) are suitable for applications requiring substantial voltage headroom. These parts feature ±10% tolerance and maintain the X7R temperature coefficient. Lead spacing is 0.197" (5.00mm), which is compatible with 0.200" (5.08mm) spacing in most PCB designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SR211C222MAT with a higher voltage-rated part?

A: Yes. All substitute parts listed with voltage ratings of 100V or higher are electrically compatible. Higher voltage ratings provide additional safety margin in the circuit. Physical dimensions and lead spacing must be verified against your PCB layout.

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

A: Tolerance specifies the allowable deviation from the nominal 2200 pF capacitance value. The SR211C222MAT allows deviation between 1760 pF and 2640 pF (±20%), while substitute parts with ±10% tolerance allow deviation between 1980 pF and 2420 pF. Tighter tolerance (±10%) is suitable for precision applications where capacitance accuracy is critical.

Q: Are the Murata RDER parts compatible with my PCB designed for the SR211C222MAT?

A: The Murata RDER series has a lead spacing of 0.197" (5.00mm) compared to the SR211C222MAT at 0.200" (5.08mm). This 0.003" difference is typically accommodated in standard PCB designs with 0.200" spacing, but physical verification is necessary. The physical dimensions (length and width) are also slightly different; confirm against your PCB footprint.

Q: Which substitute part should I choose for general-purpose replacement?

A: The C317C222K1R5TA from KEMET provides a direct 100V voltage match with improved ±10% tolerance and is the most direct functional equivalent. For applications requiring voltage margin, the C317C222K2R5TA or C322C222K2R5TA at 200V are appropriate choices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the SR211C222MAT.
