Key Parameters

Substitute Part Grouping Explanation

Substitution for the K391K15C0GF53L2 is determined by the following critical parameters: capacitance value (390 pF), rated voltage (50V), temperature coefficient (C0G/NP0), mounting type (through-hole radial), and physical dimensions including lead spacing. The tolerance specification is not a limiting factor for substitution, as tighter tolerance variants (±5%) are functionally compatible with applications designed for ±10% tolerance. All substitute parts must maintain identical capacitance, voltage rating, temperature coefficient, and mechanical form factor to ensure direct board-level compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

The K391J15C0GF53L2 is a direct substitute for the K391K15C0GF53L2. Both parts are manufactured by Vishay Beyschlag/Draloric/BC Components within the Mono-Kap™ K series and share identical electrical and mechanical specifications with the exception of tolerance. The K391J15C0GF53L2 offers ±5% tolerance compared to the ±10% tolerance of the K391K15C0GF53L2, providing improved capacitance accuracy while maintaining full compatibility. Both parts are ROHS3 compliant, active in production status, and suitable for general-purpose applications across the -55°C to 125°C operating temperature range. Selection between these parts depends on application tolerance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can K391J15C0GF53L2 replace K391K15C0GF53L2 in existing designs?

A: Yes. The K391J15C0GF53L2 is a direct substitute with identical capacitance (390 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and physical dimensions. The tighter tolerance (±5% versus ±10%) does not prevent substitution and may improve circuit performance in tolerance-sensitive applications.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts share 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). No PCB layout modifications are required for substitution.

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

A: Tolerance specifies the allowable deviation from the nominal 390 pF capacitance value. The K391K15C0GF53L2 with ±10% tolerance allows capacitance between 351 pF and 429 pF. The K391J15C0GF53L2 with ±5% tolerance allows capacitance between 370.5 pF and 409.5 pF, providing tighter control over actual capacitance values.

Q: Are both parts RoHS compliant?

A: Yes. Both K391K15C0GF53L2 and K391J15C0GF53L2 are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What applications are these capacitors designed for?

A: Both parts are rated for general-purpose applications. The C0G/NP0 temperature coefficient ensures stable capacitance performance across the -55°C to 125°C operating temperature range, making them suitable for precision timing circuits, filtering, and coupling applications.
