K331M15X7RF5TL2 Equivalent & Substitute Parts

Part Overview

The K331M15X7RF5TL2 is a 330 pF ceramic capacitor rated at 50V with X7R temperature coefficient, manufactured by Vishay Beyschlag/Draloric/BC Components. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently active in production with inventory availability. Substitute parts may be required due to packaging format changes, tolerance specifications, or temperature coefficient requirements for specific circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K331M15X7RF5TL2 is determined by the following critical parameters: capacitance value (330 pF), voltage rating (50V), mounting type (through hole radial), physical dimensions, and lead spacing. All substitute parts must maintain identical capacitance, voltage rating, and mechanical compatibility to ensure direct board-level replacement without circuit redesign.

The two qualified substitute parts differ in tolerance specification and temperature coefficient:

K331K15X7RF5TL2: Maintains X7R temperature coefficient with improved tolerance (±10% versus ±20%), available in Cut Tape packaging instead of Tape & Reel.

K331J15C0GF5TL2: Substitutes the temperature coefficient to C0G/NP0 with tighter tolerance (±5%), also available in Cut Tape packaging. This represents a functional upgrade for applications requiring superior temperature stability and capacitance accuracy.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance, ensuring regulatory and supply chain continuity. The K331K15X7RF5TL2 provides direct functional substitution with improved tolerance specification while retaining X7R temperature characteristics. The K331J15C0GF5TL2 offers enhanced performance through C0G/NP0 temperature coefficient and ±5% tolerance, suitable for applications requiring superior capacitance stability across temperature extremes. Selection between substitute parts depends on circuit tolerance requirements and temperature coefficient specifications rather than electrical performance limitations.

Frequently Asked Questions (FAQ)

Q: Can K331K15X7RF5TL2 replace K331M15X7RF5TL2 directly on the PCB?

A: Yes. Both parts share identical capacitance (330 pF), voltage rating (50V), temperature coefficient (X7R), physical dimensions, and lead spacing. The K331K15X7RF5TL2 provides improved tolerance (±10% versus ±20%) with no circuit modifications required.

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

A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance drift across temperature. The K331J15C0GF5TL2 with C0G/NP0 is suitable for precision applications requiring tighter capacitance tolerance.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical specifications remain identical between Tape & Reel and Cut Tape formats.

Q: Are all substitute parts available in equivalent quantities?

A: K331K15X7RF5TL2 and K331J15C0GF5TL2 show higher inventory levels (33,820 and 21,021 units respectively) compared to the main part (735 units), providing improved supply availability.

Q: Can tolerance specifications be mixed within a single circuit design?

A: Tolerance selection depends on circuit requirements. Applications tolerating ±20% variation can use K331M15X7RF5TL2. Applications requiring tighter tolerance should specify K331K15X7RF5TL2 (±10%) or K331J15C0GF5TL2 (±5%).
