Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K331M15X7RH53L2 is determined by the following critical parameters:

• Capacitance value: 330 pF (exact match required)
• Voltage rating: 100V minimum (equal or higher acceptable)
• Temperature coefficient: X7R (required for temperature stability)
• Mounting type: Through hole radial (physical compatibility)
• Package dimensions and lead spacing: Must match for PCB compatibility
• RoHS and REACH compliance status

The K331K15X7RH53L2 qualifies as a direct substitute based on identical capacitance, voltage rating, temperature coefficient, mounting configuration, and physical dimensions. The primary difference is tolerance specification, which is tighter (±10% versus ±20%), making this part suitable for applications requiring improved capacitance accuracy.

Engineering Selection Recommendations

The K331K15X7RH53L2 is a valid substitute for the K331M15X7RH53L2 in applications where the tighter tolerance specification (±10%) is acceptable or beneficial. Both parts maintain identical electrical performance across the specified operating temperature range and are fully compliant with ROHS3 and REACH requirements. The substitute part offers improved capacitance accuracy, which may be advantageous in precision filtering, timing, or tuning circuits. Physical compatibility is confirmed through identical package dimensions and lead spacing, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can K331K15X7RH53L2 be used as a direct replacement for K331M15X7RH53L2?

A: Yes. Both parts share identical capacitance (330 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical dimensions. The substitute features tighter tolerance (±10% versus ±20%), which is compatible with applications designed for the original part.

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

A: Tolerance defines the acceptable deviation from the nominal capacitance value. The K331M15X7RH53L2 allows capacitance between 264 pF and 396 pF, while the K331K15X7RH53L2 allows 297 pF to 363 pF. The tighter tolerance of the substitute provides more predictable capacitance values for precision applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical package dimensions (0.157" L x 0.102" W / 4.00mm x 2.60mm), height (0.220" / 5.60mm maximum), and lead spacing (0.098" / 2.50mm). No PCB layout modifications are required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both K331M15X7RH53L2 and K331K15X7RH53L2 are ROHS3 compliant and REACH unaffected, meeting the same environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For general-purpose applications where ±20% tolerance is acceptable, either part is suitable. For circuits requiring tighter capacitance accuracy, the K331K15X7RH53L2 with ±10% tolerance is the preferred choice.
