Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC471MAT3A\SB is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance: 470 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 1500V
• Tolerance: Equal to or tighter than ±20%
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)
• Thickness: Up to 0.087" (2.20mm) maximum

All identified substitute parts maintain identical capacitance, package, and mounting specifications while offering enhanced electrical performance through higher voltage ratings and improved tolerance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by KYOCERA AVX with ROHS3 compliance and MSL 1 rating, matching the environmental and regulatory status of the original 1812SC471MAT3A\SB component.

For applications requiring improved tolerance specifications: 1812GA471JAT1A (±5% tolerance) and 1812GA471KAT1A or 1812GC471KAT1A (±10% tolerance) provide tighter capacitance control than the original ±20% specification.

For applications requiring higher voltage margin: 1812GC471KAT1A (2000V rating) and 1812HC471KAT1A or KGM43ER73U471KV (3000V rating) offer increased voltage headroom while maintaining the same physical footprint and operating temperature range.

For applications requiring C0G/NP0 temperature coefficient: 1812GA471JAT1A and 1812GA471KAT1A provide superior temperature stability compared to the X7R coefficient of the original part.

For applications with strict PCB thickness constraints: 1812GC471KAT1A, 1812HC471KAT1A, and KGM43ER73U471KV maintain the original 0.071" (1.80mm) maximum thickness, while 1812GA471JAT1A and 1812GA471KAT1A have increased thickness of 0.087" (2.20mm).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating in place of the 1812SC471MAT3A\SB?

A: Yes. All substitute parts with voltage ratings of 2000V or 3000V are electrically compatible with applications designed for 1500V operation. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance.

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

A: X7R capacitors exhibit ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 capacitors maintain superior stability with minimal capacitance variation across temperature. Selection depends on circuit requirements for temperature stability.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: All substitute parts use the identical 1812 (4532 Metric) package with 0.181" L x 0.126" W footprint. However, 1812GA471JAT1A and 1812GA471KAT1A have maximum thickness of 0.087" (1.80mm) compared to 0.071" for other parts. Verify PCB clearance if height is constrained.

Q: Which substitute part offers the best tolerance specification?

A: 1812GA471JAT1A provides the tightest tolerance at ±5%, compared to ±10% for other substitutes and ±20% for the original part.

Q: Can I mix different substitute parts in the same production run?

A: All substitute parts are manufactured by KYOCERA AVX with identical ROHS3 compliance and MSL 1 ratings. Mixing is permissible from a regulatory and environmental standpoint. However, verify that tolerance and voltage specifications meet circuit requirements for each application instance.

Q: What is the inventory status of substitute parts?

A: 1812HC471KAT1A has the highest inventory at 8662 pieces, followed by 1812GA471JAT1A at 3300 pieces and 1812GC471KAT1A at 2300 pieces. Availability should be confirmed with the supplier for production quantities.
