K331M10X7RF5TH5 Equivalent & Substitute Parts

Part Overview

The K331M10X7RF5TH5 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 Active status and ROHS3 compliant. Substitute parts may be required due to packaging format availability, tolerance specifications, or inventory constraints while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the K331M10X7RF5TH5 is determined by the following criteria:

Critical Parameters (Must Match):

• Capacitance: 330 pF
• Voltage Rating: 50V
• Mounting Type: Through Hole
• Lead Spacing: 0.197" (5.00mm)
• Package Type: Radial

Allowable Variations:

• Tolerance: ±20%, ±10%, or ±5% (tighter tolerances are acceptable)
• Temperature Coefficient: X7R or C0G/NP0 (both provide stable performance across operating range)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)
• Physical dimensions: Minor variations in length and height are acceptable provided lead spacing remains constant

The two substitute parts listed below meet all critical parameters while offering alternative tolerance and temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are Active status components manufactured by Vishay Beyschlag/Draloric/BC Components and maintain ROHS3 compliance. Selection between the main part and substitutes depends on application-specific requirements:

K331M10X7RF5TH5 is suitable for applications where ±20% tolerance is acceptable and X7R temperature stability is required.

K331K15X7RF5TH5 provides improved tolerance specification (±10%) while maintaining X7R temperature coefficient characteristics, making it appropriate for circuits requiring tighter capacitance control.

K331J15C0GF5TH5 offers the tightest tolerance (±5%) with C0G/NP0 temperature coefficient, which provides superior temperature stability and is preferred for precision analog circuits and frequency-critical applications.

All parts share identical lead spacing and through-hole mounting configuration, ensuring direct board-level compatibility. Packaging format differences (Tape & Reel versus Cut Tape) do not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can K331K15X7RF5TH5 be used as a direct replacement for K331M10X7RF5TH5?

A: Yes. Both parts have identical capacitance (330 pF), voltage rating (50V), temperature coefficient (X7R), lead spacing (5.00mm), and mounting type (Through Hole Radial). The K331K15X7RF5TH5 offers improved tolerance (±10% versus ±20%), making it a compatible upgrade.

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

A: Both temperature coefficients provide stable capacitance across the -55°C to 125°C operating range. X7R allows ±15% capacitance change over temperature, while C0G/NP0 allows ±0.3% change, making C0G/NP0 suitable for precision applications requiring minimal temperature-dependent drift.

Q: Are there physical dimension differences between these parts?

A: The main part K331M10X7RF5TH5 has dimensions of 0.142" L x 0.091" W with 0.244" seated height. Substitutes K331K15X7RF5TH5 and K331J15C0GF5TH5 have dimensions of 0.157" L x 0.102" W with 0.260" seated height. Lead spacing remains constant at 0.197" (5.00mm) for all parts, ensuring PCB compatibility.

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

A: No. Packaging format affects only handling and assembly logistics. Electrical and mechanical specifications remain identical regardless of whether the part is supplied in Tape & Reel or Cut Tape format.

Q: Which substitute should be selected for cost optimization?

A: Selection should be based on application requirements rather than cost alone. K331M10X7RF5TH5 and K331K15X7RF5TH5 are suitable for general-purpose applications. K331J15C0GF5TH5 should be selected only when the tighter tolerance and superior temperature stability of C0G/NP0 are required by circuit design specifications.
