Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812SC151KAT1A\SB are identified based on the following criteria:

Primary Matching Parameters:

• Capacitance: 150 pF (exact match required)
• Tolerance: ±10% (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)

Variable Parameters Allowing Substitution:

• Voltage - Rated: Equal to or greater than 1500V
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general-purpose applications)
• Manufacturer: Different manufacturers permitted if all other parameters align

The substitute parts listed below maintain identical capacitance, tolerance, package, and mounting specifications while offering equal or enhanced voltage ratings and alternative temperature coefficient options suitable for the same application space.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full RoHS3 compliance with REACH unaffected designation. Selection between the main part and substitutes depends on voltage requirement specifications for the application circuit.

1812SC151KAT1A\SB (Main Part): Use when circuit design specifies 1500V rated voltage with X7R temperature coefficient characteristics. Suitable for general-purpose high-voltage applications within the 1.5kV specification envelope.

1812GA151KAT1A (Upgrade Substitute): Use when circuit design permits 2000V rated voltage with C0G/NP0 temperature coefficient. Offers higher voltage margin while maintaining identical footprint and capacitance. Thickness increases to 0.087" (2.20mm); verify PCB assembly clearance before substitution.

C4532C0G3F151K160KA (MFR Recommended Substitute): Use when circuit design permits 3000V rated voltage with C0G/NP0 temperature coefficient. Provides maximum voltage headroom for high-voltage applications. Slight dimensional variation in length (0.177" vs 0.181") and thickness (0.071" vs 0.087") requires PCB footprint verification. Highest inventory availability (24,949 units) supports supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 1812GA151KAT1A replace 1812SC151KAT1A\SB in any application?

A: Yes, provided the circuit design permits operation at 2000V rated voltage. The substitute maintains identical capacitance (150 pF), tolerance (±10%), package footprint (1812/4532 Metric), and mounting type. The increased thickness of 0.087" (2.20mm) versus 0.071" (1.80mm) requires verification of PCB assembly clearance and component placement constraints.

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

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides ±30 ppm/°C capacitance stability across the same range. Both are acceptable for general-purpose applications; selection depends on circuit performance requirements for temperature-dependent capacitance variation.

Q: Is C4532C0G3F151K160KA physically compatible with the 1812 footprint?

A: The C4532C0G3F151K160KA maintains the 1812 (4532 Metric) package designation with identical width (0.126" / 3.20mm) and height (0.071" / 1.80mm). Length is 0.177" (4.50mm) versus 0.181" (4.60mm) for the main part. This 0.004" (0.10mm) difference is within standard PCB footprint tolerance; however, verify specific PCB design files to confirm placement compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts maintain RoHS3 compliance and REACH unaffected status, suitable for applications requiring environmental regulatory compliance.

Q: Which substitute offers the best supply chain availability?

A: C4532C0G3F151K160KA (TDK Corporation) maintains the highest inventory level at 24,949 units in stock, compared to 1124 units for 1812GA151KAT1A and 946 units for the main part 1812SC151KAT1A\SB.
