Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the KGM43AR72D333JV are determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.033 µF
• Tolerance: ±5%
• Package / Case: 1812 (4532 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical footprint: 0.177" L x 0.126" W (4.50mm x 3.20mm)

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 200V
• Temperature Coefficient: X7R, C0G, or NP0 (all provide stable capacitance across the operating temperature range)
• Operating Temperature Range: Must support minimum -55°C to 125°C
• RoHS and REACH compliance status

The substitute parts listed below meet all mandatory matching parameters and maintain electrical compatibility through equal or superior voltage ratings and temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed are active production components with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

KGM43AR72D333JV (KYOCERA AVX): Primary specification part with 200V rating and X7R temperature coefficient. Suitable for standard general purpose applications within the specified voltage and temperature parameters.

C1812C333JAGAC7800 (KEMET): Upgrade option with 250V voltage rating and C0G/NP0 temperature coefficient. The C0G/NP0 characteristic provides superior temperature stability compared to X7R. Reduced thickness (1.10mm vs 1.40mm) may offer advantages in space-constrained designs. Suitable for applications requiring enhanced temperature stability.

C4532NP02J333J200KA (TDK Corporation): High-voltage rated option at 630V with C0G/NP0 temperature coefficient and extended operating temperature range to 150°C. Increased thickness (2.20mm) accommodates the higher voltage rating. Suitable for applications requiring significant voltage margin or elevated temperature operation beyond 125°C.

Frequently Asked Questions (FAQ)

Q: Can C1812C333JAGAC7800 or C4532NP02J333J200KA be used as direct replacements for KGM43AR72D333JV?

A: Yes. Both substitute parts maintain identical capacitance (0.033 µF), tolerance (±5%), and physical footprint (1812/4532 Metric). The higher voltage ratings (250V and 630V respectively) provide electrical compatibility with the 200V specification. All three parts are surface mount MLCCs with MSL 1 rating and ROHS3 compliance.

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

A: X7R provides ±15% capacitance variation across -55°C to 125°C. C0G/NP0 provides superior stability with ±0.3% variation across the same temperature range. Both meet the operating temperature requirements of the original specification. C0G/NP0 is preferred for applications requiring tighter capacitance tolerance across temperature extremes.

Q: Are there physical space considerations when substituting these parts?

A: Yes. The C1812C333JAGAC7800 has reduced thickness (1.10mm) compared to the original (1.40mm), allowing use in space-constrained PCB designs. The C4532NP02J333J200KA has increased thickness (2.20mm) due to its 630V rating; verify PCB clearance before selection. All three maintain identical length and width dimensions (4.50mm x 3.20mm).

Q: Which substitute part should be selected for maximum design margin?

A: The C4532NP02J333J200KA offers the highest voltage rating (630V) and extended temperature range (-55°C to 150°C), providing maximum design margin. However, verify that the increased thickness (2.20mm) is compatible with PCB layout constraints.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. Inventory availability varies by manufacturer and distributor.
