SR752C224MAT Equivalent & Substitute Parts

Part Overview

The SR752C224MAT is a 0.22 µF ceramic capacitor rated at 200V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This through-hole radial component is designed for general-purpose applications and is currently in active production status with 711 units in stock.

Equivalent and substitute parts are necessary when the original SR752C224MAT becomes unavailable, when alternative packaging formats are required, or when design specifications allow for higher voltage ratings or improved tolerance characteristics. The substitute parts listed maintain the core electrical specifications (0.22 µF capacitance, X7R temperature stability, -55°C to 125°C operating range) while offering variations in voltage rating, tolerance, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR752C224MAT is determined by the following criteria:

Core Electrical Requirements (Non-Negotiable):

• Capacitance: 0.22 µF (exact match required)
• Temperature Coefficient: X7R (maintains temperature stability across operating range)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package Type: Radial (lead configuration)
• Lead Spacing: 0.200" (5.08mm) (PCB footprint compatibility)

Allowable Variations:

• Voltage Rating: 200V or higher (higher ratings provide design margin and are backward compatible)
• Tolerance: ±20% or tighter (tighter tolerances are acceptable upgrades)
• Lead Style: Formed Leads or Straight (both compatible with through-hole assembly)
• Packaging Format: Bulk or Cut Tape (inventory format does not affect electrical performance)

Substitute parts are grouped into three categories based on voltage rating: 200V direct equivalents, 250V upgrades, and higher voltage options (500V and 630V).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (200V Rating): The C340C224K2R5TA from KEMET is the primary direct equivalent. It maintains the 200V voltage rating while offering improved tolerance (±10% versus ±20%), is in active production status, and meets ROHS3 compliance. This part is suitable for direct substitution in existing designs.

Voltage Upgrade Options (250V and Higher): When circuit design margins permit, the 250V-rated parts (FK20X7R2E224KN000 and RDER72E series) and 630V-rated parts (RDER72J series) provide enhanced reliability through higher voltage headroom. All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original SR752C224MAT.

Product Status Consideration: The FK20X7R2E224KN000 from TDK is marked "Not For New Designs," indicating it is in end-of-life status. This part should be used only for legacy system maintenance or repair applications where design continuity is required. For new designs, select from parts with "Active" product status: C340C224K2R5TA, C340C224MCR5TA, RDER72E224K3K1H03B, RDER72E224K3M1H03A, RDER72J224K5B1H03B, or RDER72J224K5E1H03A.

Packaging Format: Bulk and Cut Tape packaging formats are functionally equivalent. Selection should be based on procurement volume and assembly line requirements. The Murata RDER72E224K3M1H03A is available in Cut Tape format with the highest inventory (6,681 units), while the RDER72J224K5E1H03A offers the largest stock in 630V rating (21,300 units in Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can I use a 250V or 630V rated capacitor in place of the 200V SR752C224MAT?

A: Yes. Higher voltage ratings are backward compatible with lower voltage applications. A 250V or 630V capacitor will function correctly in a circuit designed for 200V operation, providing additional safety margin. The capacitance (0.22 µF), temperature coefficient (X7R), and operating temperature range remain identical.

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

A: Tolerance specifies the allowable deviation from the nominal 0.22 µF capacitance value. The SR752C224MAT allows ±20% (0.176 µF to 0.264 µF), while substitute parts with ±10% tolerance (0.198 µF to 0.242 µF) provide tighter capacitance control. Tighter tolerance is an acceptable upgrade for applications requiring more precise capacitance values.

Q: Are the lead spacing differences between 0.200" and 0.197" significant?

A: The 0.003" (0.076mm) difference is within standard PCB manufacturing tolerances and does not affect interchangeability for through-hole assembly. Both lead spacings are compatible with standard 0.200" (5.08mm) pitch PCB footprints used for radial capacitors.

Q: What is the difference between Formed Leads and Straight leads?

A: Formed Leads are pre-bent for insertion into PCB holes, while Straight leads require manual bending or use of automated insertion equipment. Both styles are compatible with through-hole assembly. Lead style selection depends on assembly process capability and operator preference.

Q: Why is the FK20X7R2E224KN000 marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status and the manufacturer is discontinuing production. While existing inventory may be available, new designs should specify parts with "Active" product status to ensure long-term supply chain stability and continued manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, matching the regulatory compliance profile of the original SR752C224MAT. This ensures compatibility with environmental and hazardous substance regulations.

Q: Which substitute part has the best availability?

A: The RDER72J224K5E1H03A from Murata Electronics offers the highest inventory level at 21,300 units in Cut Tape packaging. For 250V applications, the RDER72E224K3M1H03A provides 6,681 units. For direct 200V equivalents, the C340C224K2R5TA from KEMET has 2,200 units available.
