Engineering Selection Recommendations
All substitute parts listed maintain ROHS3 compliance and active product status. Selection between substitute parts depends on circuit voltage requirements and tolerance specifications:
For applications requiring voltage margins above 630V, the 1812AC102KAT1A and 1812AC102MAT1A provide 1000V rating in the same 0.071" thickness. The 1812GC102KAT1A and 1812GC102MAT1A offer 2000V rating, while 1812HC102KAT1A and KGM43FR73U102KV provide 3000V rating with increased thickness of 0.087" to 0.087" (2.21mm).
For tolerance-critical applications, parts with ±10% tolerance (1812AC102KAT1A, 1812GC102KAT1A, 1812HC102KAT1A, 1812WC102KAT1A, KGM43ER73D102KV, KGM43FR73U102KV) provide tighter specifications than the original ±20% tolerance.
The KGM series (KGM43ER73D102KV, KGM43ER73D102MV, KGM43FR73U102KV) represents the KGM - HV product line with equivalent electrical performance to the standard 1812 series.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with higher voltage rating in place of the 1812CC102MAT3A?
A: Yes. All substitute parts with equal or higher voltage ratings are electrically compatible. A 1000V-rated part operates safely in a 630V circuit. Higher voltage ratings provide additional safety margin and do not degrade circuit performance.
Q: What is the difference between ±10% and ±20% tolerance parts?
A: Tolerance specifies the allowable deviation from the nominal 1000 pF capacitance value. ±10% tolerance parts range from 900 pF to 1100 pF, while ±20% tolerance parts range from 800 pF to 1200 pF. Applications requiring precise capacitance values should use ±10% tolerance parts.
Q: Are the 1812HC102KAT1A and KGM43FR73U102KV interchangeable?
A: Both parts have identical electrical specifications (1000 pF, ±10%, 3000V, X7R, -55°C ~ 125°C) and package footprint (1812). The primary difference is the thickness: 1812HC102KAT1A is 0.087" (2.20mm) while KGM43FR73U102KV is 0.087" (2.21mm). This minimal difference does not affect interchangeability in standard applications.
Q: Does changing from 1812CC102MAT3A to 1812WC102KAT1A affect PCB layout?
A: The footprint remains identical (1812 / 4532 Metric, 0.181" L x 0.126" W). However, the thickness increases from 0.071" (1.80mm) to 0.110" (2.80mm). Verify clearance in the Z-axis direction for components or enclosures in close proximity.
Q: What packaging options are available for substitute parts?
A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats. Verify packaging compatibility with your assembly process before selection.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All parts listed maintain ROHS3 compliance and are suitable for applications requiring RoHS certification.
