Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K331M10X7RH53L2 is determined by the following critical parameters:

• Capacitance value must remain 330 pF
• Voltage rating must be equal to or greater than 100V
• Temperature coefficient must be X7R to maintain thermal stability
• Mounting type must be Through Hole with Radial configuration
• Lead spacing must be 0.098" (2.50mm) to ensure PCB compatibility
• RoHS3 compliance must be maintained

The K331K15X7RH53L2 qualifies as a substitute because it maintains identical capacitance, voltage rating, temperature coefficient, mounting configuration, and lead spacing. The primary difference is a tighter tolerance specification (±10% versus ±20%), which represents an upgrade in precision without compromising electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the K331M10X7RH53L2 and K331K15X7RH53L2 are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current production designs. The K331K15X7RH53L2 offers improved tolerance performance (±10% versus ±20%), which may be advantageous in applications requiring tighter capacitance specifications. However, the substitute part has slightly larger physical dimensions and height, requiring verification of available PCB space. Lead spacing remains identical at 0.098" (2.50mm), ensuring footprint compatibility. Selection should be based on tolerance requirements and available board real estate.

Frequently Asked Questions (FAQ)

Q: Can K331K15X7RH53L2 be used as a direct replacement for K331M10X7RH53L2?

A: Yes, provided PCB layout accommodates the larger physical dimensions (0.157" x 0.102" versus 0.142" x 0.091") and increased height (0.220" versus 0.205"). Lead spacing is identical, ensuring electrical compatibility.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs: K331M10X7RH53L2 has ±20% tolerance, while K331K15X7RH53L2 has ±10% tolerance. Both maintain identical capacitance, voltage rating, and temperature coefficient.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts feature X7R temperature coefficient and operate across -55°C to 125°C, providing stable capacitance performance throughout this range.

Q: Do dimensional differences affect circuit performance?

A: No. Dimensional differences do not affect electrical performance. However, physical size must be verified against PCB layout constraints before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both K331M10X7RH53L2 and K331K15X7RH53L2 are ROHS3 compliant and REACH unaffected.
