K331M15X7RF5TH5 Equivalent & Substitute Parts

Part Overview

The K331M15X7RF5TH5 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. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained while offering improved tolerance or packaging alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K331M15X7RF5TH5 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 330 pF (exact match required)
• Voltage Rating: 50V (equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Physical Dimensions: 0.157" L x 0.102" W (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Tolerance: May be tighter (improved from ±20% to ±10% or ±5%)
• Temperature Coefficient: May be upgraded from X7R to C0G/NP0 (more stable)
• Packaging Format: May differ (Tape & Reel to Cut Tape acceptable)

Two substitute parts meet these criteria with improved tolerance specifications while maintaining identical electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

K331K15X7RF5TH5 (Upgrade Substitute): This part provides improved tolerance of ±10% compared to the original ±20%, while maintaining identical X7R temperature coefficient and all mechanical specifications. Both parts are ROHS3 compliant and REACH unaffected. The primary difference is packaging format (Cut Tape versus Tape & Reel) and significantly higher inventory availability. This substitute is suitable for applications where tighter capacitance tolerance is beneficial without requiring temperature coefficient modification.

K331J15C0GF5TH5 (Manufacturer Recommended Substitute): This part upgrades both tolerance to ±5% and temperature coefficient to C0G/NP0, providing superior stability across the operating temperature range compared to X7R. All mechanical dimensions, lead spacing, and mounting characteristics remain identical. Both parts are ROHS3 compliant and REACH unaffected. This substitute is recommended for applications requiring maximum capacitance stability and precision, with the highest inventory availability of the three options.

All three parts are active products from the same manufacturer series and maintain full electrical and mechanical compatibility for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can K331K15X7RF5TH5 be used as a direct replacement for K331M15X7RF5TH5?

A: Yes. Both parts have identical capacitance (330 pF), voltage rating (50V), temperature coefficient (X7R), and all mechanical specifications including lead spacing (5.00mm) and physical dimensions. The K331K15X7RF5TH5 offers improved tolerance (±10% versus ±20%) and is a direct board-level substitute.

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

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance variation across temperature. The K331J15C0GF5TH5 uses C0G/NP0 for applications requiring maximum temperature stability.

Q: Are there packaging differences between these parts?

A: The K331M15X7RF5TH5 is supplied in Tape & Reel (TR) format. Both substitute parts (K331K15X7RF5TH5 and K331J15C0GF5TH5) are supplied in Cut Tape (CT) format. All three have identical component specifications and board-level compatibility.

Q: Which substitute should be selected for general-purpose applications?

A: The K331K15X7RF5TH5 is suitable for general-purpose applications, offering improved tolerance while maintaining the same temperature coefficient. The K331J15C0GF5TH5 is recommended when superior temperature stability and tolerance precision are required.

Q: Are all three parts RoHS and REACH compliant?

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

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts have identical lead spacing (5.00mm), physical dimensions (4.00mm x 2.60mm), and height (6.60mm maximum seated height), enabling direct substitution without PCB layout modifications.
