Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K391K10C0GF53L2 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 390 pF
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0
• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.098" (2.50mm)

Allowable Variation:

• Tolerance: May be tighter (lower tolerance value) than the original ±10%
• Physical dimensions: May vary within standard radial package specifications
• Inventory status: Independent of substitution eligibility

The K391J15C0GF53L2 qualifies as a substitute because it maintains all mandatory electrical parameters while offering improved tolerance specification (±5% versus ±10%), making it suitable for applications requiring tighter capacitance control.

Parameter Comparison

Engineering Selection Recommendations

Both the K391K10C0GF53L2 and K391J15C0GF53L2 are active production components with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

The K391J15C0GF53L2 provides tighter tolerance control (±5%) compared to the original part (±10%), making it suitable for circuits where capacitance precision is critical. Both parts maintain identical electrical performance across the full operating temperature range and are mechanically compatible for through-hole PCB assembly.

Selection between these parts should be based on tolerance requirements of the specific application and component availability.

Frequently Asked Questions (FAQ)

Q: Can K391J15C0GF53L2 be used as a direct replacement for K391K10C0GF53L2?

A: Yes. Both parts share identical capacitance (390 pF), voltage rating (50V), temperature coefficient (C0G/NP0), lead spacing (2.50mm), and mounting configuration. The K391J15C0GF53L2 offers improved tolerance specification, making it functionally compatible for direct substitution.

Q: What is the difference between ±10% and ±5% tolerance?

A: Tolerance defines the allowable deviation from the nominal capacitance value. The K391K10C0GF53L2 allows capacitance between 351 pF and 429 pF, while the K391J15C0GF53L2 allows 370.5 pF to 409.5 pF. Tighter tolerance (±5%) is beneficial for precision circuits but may not be necessary for general-purpose applications.

Q: Are there physical dimension differences between these parts?

A: Yes. The K391K10C0GF53L2 measures 0.142" L × 0.091" W with 0.205" seated height, while the K391J15C0GF53L2 measures 0.157" L × 0.102" W with 0.220" seated height. Both fit standard radial package footprints with 2.50mm lead spacing, but PCB layout clearance should be verified for the larger substitute.

Q: Do both parts meet current compliance requirements?

A: Yes. Both K391K10C0GF53L2 and K391J15C0GF53L2 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications requiring tighter capacitance control, the K391J15C0GF53L2 (±5%) is appropriate. For general-purpose applications where ±10% tolerance is acceptable, either part is suitable based on availability and cost considerations.
