Substitute Part Grouping Explanation

Substitution for the K821K15C0GF53L2 is based on the following allowed parameters:

• Capacitance value: 820 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 50V (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Physical dimensions: 0.157" L x 0.102" W, lead spacing 0.098" (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part K821K15X7RF53L2 meets all these criteria. The primary difference is the temperature coefficient specification: X7R instead of C0G/NP0. Both temperature coefficients support the same operating temperature range and are suitable for general-purpose applications within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both K821K15C0GF53L2 and K821K15X7RF53L2 are active production parts with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application-specific requirements for temperature coefficient stability. The C0G/NP0 coefficient provides superior capacitance stability across temperature variations, while the X7R coefficient offers broader temperature performance characteristics within the same operating range. Both parts maintain the same physical footprint, electrical ratings, and compliance certifications, ensuring direct compatibility in through-hole radial mounting applications.

Frequently Asked Questions (FAQ)

Q: Can K821K15X7RF53L2 be used as a direct replacement for K821K15C0GF53L2?

A: Yes, within the constraints of application requirements. Both parts share identical capacitance (820 pF), tolerance (±10%), voltage rating (50V), operating temperature range (-55°C ~ 125°C), physical dimensions, and compliance certifications. The difference lies in temperature coefficient specification: C0G/NP0 versus X7R. Selection depends on the specific temperature stability requirements of your application.

Q: What is the difference between C0G/NP0 and X7R temperature coefficients?

A: C0G and NP0 are equivalent designations for temperature coefficients with minimal capacitance change across the operating temperature range. X7R is a broader temperature coefficient classification that also supports the -55°C ~ 125°C operating range. The choice between them is application-dependent based on required capacitance stability characteristics.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions of 0.157" L x 0.102" W (4.00mm x 2.60mm), lead spacing of 0.098" (2.50mm), and maximum seated height of 0.220" (5.60mm). They are mechanically interchangeable in through-hole radial mounting applications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both K821K15C0GF53L2 and K821K15X7RF53L2 are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications.

Q: What inventory status should I consider?

A: K821K15C0GF53L2 has 678 pieces in stock, while K821K15X7RF53L2 has 19,046 pieces in stock. Availability may influence selection based on project timeline and quantity requirements.
