Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A331M15X7RH5TAA are qualified based on the following criteria:

Core Matching Parameters:

• Capacitance value: 330 pF (exact match required)
• Voltage rating: 100V (minimum requirement)
• Mounting type: Through Hole (axial configuration)
• Operating temperature range: -55°C to 125°C (minimum coverage required)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Tolerance: May be tighter (±10% or ±5%) than the original ±20%
• Temperature coefficient: May be upgraded from X7R to C0G/NP0 for improved stability
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) are interchangeable for component sourcing
• Physical dimensions: Minor variations acceptable within axial through-hole form factor constraints

Parameter Comparison

Engineering Selection Recommendations

A331K15X7RH5TAA is a direct upgrade within the Vishay product family, offering improved tolerance (±10% versus ±20%) while maintaining identical electrical and mechanical specifications. Both parts share the same capacitance, voltage rating, temperature coefficient, and physical dimensions. This substitute is suitable for applications requiring tighter capacitance tolerance without design modification.

C410C331J1G5TA7200 from KEMET provides superior tolerance (±5%) and upgraded temperature coefficient (C0G/NP0 versus X7R), resulting in improved temperature stability and lower capacitance drift. Physical dimensions are slightly larger (0.100" Dia x 0.170" L versus 0.098" Dia x 0.150" L). This substitute is applicable in designs where PCB layout accommodates the minor size increase and where enhanced temperature stability is beneficial. All three parts maintain ROHS3 compliance and identical voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can A331K15X7RH5TAA replace A331M15X7RH5TAA directly?

A: Yes. Both parts are identical in capacitance (330 pF), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical dimensions (0.098" Dia x 0.150" L). The A331K15X7RH5TAA offers tighter tolerance (±10% versus ±20%), making it a direct functional upgrade.

Q: What are the differences between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change over the -55°C to 125°C temperature range. C0G/NP0 provides superior stability with minimal capacitance change across temperature. The C410C331J1G5TA7200 with C0G/NP0 is suitable for applications requiring predictable capacitance performance across temperature extremes.

Q: Will C410C331J1G5TA7200 fit in the same PCB footprint?

A: The C410C331J1G5TA7200 has slightly larger dimensions (0.100" Dia x 0.170" L) compared to the original (0.098" Dia x 0.150" L). PCB layout must accommodate this minor size increase. Both maintain straight lead style and axial through-hole mounting compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. A331M15X7RH5TAA, A331K15X7RH5TAA, and C410C331J1G5TA7200 are all ROHS3 Compliant.

Q: What tolerance should I specify for my design?

A: Tolerance selection depends on circuit requirements. Use ±20% (A331M15X7RH5TAA) for general-purpose applications with loose tolerances. Use ±10% (A331K15X7RH5TAA) for improved accuracy. Use ±5% (C410C331J1G5TA7200) for precision circuits requiring tight capacitance control.
