Key Parameters

Substitute Part Grouping Explanation

Substitution of the C317C331K2R5CA is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 330 pF (fixed)
• Voltage rating: Equal to or greater than 200V
• Temperature coefficient: X7R or C0G/NP0 (C0G/NP0 represents an upgrade path)
• Mounting type: Through hole radial configuration
• Lead spacing: 0.200" (5.08mm)
• Operating temperature range: -55°C to 125°C minimum

Substitution Categories:

1. Direct Equivalent (Same Specifications): Parts maintaining identical electrical specifications with improved product status or packaging
2. Tolerance Upgrade: Parts with ±5% tolerance (tighter tolerance than ±10%)
3. Voltage Upgrade: Parts rated at 250V or 500V (higher voltage rating than 200V)
4. Temperature Coefficient Upgrade: Parts with C0G/NP0 coefficient (superior temperature stability compared to X7R)

All substitute parts maintain the same 330 pF capacitance, -55°C to 125°C operating range, through-hole radial mounting, and 0.200" lead spacing as the original component.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

C317C331K2R5TA is the primary direct replacement for C317C331K2R5CA. Both parts maintain identical electrical specifications: 330 pF ±10% at 200V with X7R temperature coefficient. The C317C331K2R5TA is active product status and ROHS3 compliant, addressing the obsolescence of the original part while preserving all electrical and mechanical characteristics. This part is suitable for direct substitution in existing designs without circuit modification.

Tolerance Upgrade Path:

C317C331J2G5TA provides a tolerance upgrade to ±5% while maintaining 200V rating and X7R temperature coefficient. This part is active and ROHS3 compliant. The tighter tolerance specification improves circuit performance in applications requiring enhanced capacitance accuracy. Physical dimensions remain compatible with the original part.

Voltage Upgrade Path:

C317C331KCR5TA offers a voltage rating upgrade to 500V while maintaining ±10% tolerance and X7R temperature coefficient. This part is active and ROHS3 compliant. The higher voltage rating provides additional design margin in high-voltage applications. Physical dimensions are slightly larger (0.120" width vs. 0.100"), requiring verification of PCB layout compatibility.

Temperature Coefficient Upgrade Path:

Parts with C0G/NP0 temperature coefficient (C317C331J2G5TA, C322C331J2G5TA, C323C331J2G5TA, C322C331JCG5TA, C322C331KAG5TA, C323C331KAG5TA, C328C331JAG5TA, C328C331KAG5TA) provide superior temperature stability compared to X7R. All are active product status and ROHS3 compliant. These parts are suitable for applications requiring stable capacitance across the full operating temperature range.

Voltage and Tolerance Combination Upgrades:

C322C331JCG5TA combines 500V rating with ±5% tolerance and C0G/NP0 coefficient, providing maximum performance specifications. C322C331KAG5TA and C323C331KAG5TA offer 250V rating with ±10% tolerance and C0G/NP0 coefficient. C328C331JAG5TA and C328C331KAG5TA provide 250V rating with C0G/NP0 coefficient and ±5% or ±10% tolerance respectively.

Frequently Asked Questions (FAQ)

Q: Can C317C331K2R5TA be used as a direct replacement for C317C331K2R5CA?

A: Yes. C317C331K2R5TA is the direct equivalent with identical electrical specifications (330 pF ±10% 200V X7R). The primary difference is product status (active vs. obsolete) and RoHS compliance. Physical dimensions and lead spacing are identical, allowing direct PCB substitution.

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

A: X7R temperature coefficient specifies capacitance change of ±15% across the -55°C to 125°C operating range. C0G/NP0 temperature coefficient specifies capacitance change of 0±30 ppm/°C, providing significantly superior temperature stability. C0G/NP0 parts are suitable for applications requiring stable capacitance performance across temperature extremes.

Q: Can I use a 500V rated capacitor in place of a 200V rated capacitor?

A: Yes. Voltage rating represents the maximum safe operating voltage. A 500V rated capacitor (C317C331KCR5TA or C322C331JCG5TA) can be used in a 200V application. However, physical dimensions may differ, requiring PCB layout verification. The 500V parts are slightly larger and may not fit in space-constrained designs.

Q: What does ±10% tolerance mean compared to ±5%?

A: Tolerance specifies the allowable deviation from the nominal capacitance value. A 330 pF ±10% capacitor has actual capacitance between 297 pF and 363 pF. A 330 pF ±5% capacitor has actual capacitance between 313.5 pF and 346.5 pF. Tighter tolerance (±5%) provides more precise capacitance values for applications requiring higher accuracy.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original C317C331K2R5CA is RoHS non-compliant. Substitution with any listed part ensures regulatory compliance for new designs and manufacturing.

Q: Do the larger package sizes (C322C, C323C, C328C series) fit in the same PCB footprint as the original C317C?

A: No. The C322C, C323C, and C328C series have larger physical dimensions and greater height. C322C and C323C parts measure 0.200" x 0.125" with heights of 0.260" and 0.300" respectively, compared to the C317C at 0.150" x 0.100" with 0.200" height. PCB layout must be verified before substitution. The C317C331J2G5TA maintains identical dimensions to the original part.

Q: Which substitute part offers the best overall performance upgrade?

A: C322C331JCG5TA provides maximum performance specifications: 500V voltage rating, ±5% tolerance, and C0G/NP0 temperature coefficient. This part is suitable for demanding applications requiring high voltage margin, precise capacitance, and stable temperature performance. Physical dimensions require PCB layout verification.

Q: Can I substitute parts with different lead spacing?

A: No. All listed substitute parts maintain 0.200" (5.08mm) lead spacing, matching the original component. Lead spacing is a critical mechanical parameter that determines PCB footprint compatibility. Parts with different lead spacing are not interchangeable.
