K331K15C0GF5TL2 Equivalent & Substitute Parts

Part Overview

The K331K15C0GF5TL2 is a 330 pF ceramic capacitor rated at 50V with C0G/NP0 temperature coefficient, manufactured by Vishay Beyschlag/Draloric/BC Components. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across temperature variations. The part is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: capacitance value (330 pF), voltage rating (50V minimum), mounting type (through hole radial), physical dimensions, and lead spacing. Temperature coefficient and tolerance variations are permitted within the constraints of the application requirements.

Two substitute parts are identified:

K331J15C0GF5TL2 qualifies as an upgrade substitute due to tighter tolerance (±5% versus ±10%) while maintaining identical capacitance, voltage rating, temperature coefficient (C0G/NP0), and physical dimensions. Packaging differs (Cut Tape versus Tape & Reel).

K331K15X7RF5TL2 qualifies as a manufacturer-recommended substitute with matching capacitance, voltage rating, tolerance (±10%), and physical dimensions. The temperature coefficient differs (X7R versus C0G/NP0), which affects temperature stability characteristics but maintains compatibility for general-purpose applications within the specified operating range.

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance. Selection between the main part and substitutes depends on specific application requirements:

K331J15C0GF5TL2 provides improved capacitance tolerance (±5%) for applications requiring tighter value control, with identical electrical and thermal characteristics. This part is suitable when tolerance specifications demand higher precision.

K331K15X7RF5TL2 is the manufacturer-recommended alternative, offering higher inventory availability. The X7R temperature coefficient exhibits greater capacitance variation across temperature extremes compared to C0G/NP0, but remains within the -55°C to 125°C operating range. This part is suitable for general-purpose applications where temperature stability is less critical than for C0G/NP0 specifications.

Packaging format differences (Tape & Reel versus Cut Tape) affect procurement and assembly processes but do not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can K331J15C0GF5TL2 be used as a direct replacement for K331K15C0GF5TL2?

A: Yes. Both parts share identical capacitance (330 pF), voltage rating (50V), temperature coefficient (C0G/NP0), physical dimensions, and lead spacing. K331J15C0GF5TL2 offers tighter tolerance (±5% versus ±10%), making it suitable for applications requiring improved capacitance accuracy.

Q: What is the primary difference between K331K15X7RF5TL2 and the main part?

A: The temperature coefficient differs. K331K15X7RF5TL2 uses X7R, which exhibits greater capacitance variation across temperature extremes compared to C0G/NP0. Both maintain the same capacitance value, voltage rating, tolerance, and physical dimensions. X7R is suitable for general-purpose applications; C0G/NP0 is preferred for temperature-sensitive circuits.

Q: Are packaging format differences significant for substitution?

A: Packaging format (Tape & Reel versus Cut Tape) affects procurement and assembly logistics but does not impact electrical performance or mechanical fit. Both formats are compatible with standard PCB assembly equipment.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which substitute part offers the best availability?

A: K331K15X7RF5TL2 has the highest inventory level (33,820 pcs) compared to K331J15C0GF5TL2 (21,021 pcs) and the main part (971 pcs).
