Substitute Part Grouping Explanation

Substitution is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications: 1000 pF capacitance, ±5% tolerance, 100V rating, X7R temperature coefficient, and 0805 package. These parts are interchangeable without circuit redesign.

Upgrade Substitutes - Tighter Tolerance (C0G/NP0) offer ±1% or ±2% tolerance with C0G/NP0 temperature coefficient instead of X7R. These provide superior stability and lower capacitance drift across temperature ranges, suitable for precision applications. Voltage rating remains 100V except where noted.

Upgrade Substitutes - Higher Voltage (X7R) maintain X7R temperature coefficient and ±5% tolerance but increase voltage rating to 200V. These provide additional voltage margin for the same capacitance and package.

Cross-Manufacturer Direct Equivalents from KEMET, YAGEO, and Samsung Electro-Mechanics provide identical 1000 pF, ±5%, 100V, X7R specifications in 0805 package with equivalent performance characteristics.

Engineering Selection Recommendations

For Direct Replacement: Select KGM21NR72A102JT (KYOCERA AVX), C0805C102J1RAC7800 (KEMET), or CL21B102JCANNNC (Samsung Electro-Mechanics). These maintain identical electrical specifications with 100V X7R 1000 pF ±5% ratings. All are Active status and ROHS3 compliant. CL21B102JCANNNC offers highest inventory availability at 122,177 pieces.

For Precision Applications: Select KGM21BCG2A102FT or KGM21BCG2A102GT (KYOCERA AVX) or C0805C102F1GAC7800 or C0805C102G1GAC7800 (KEMET). These upgrade substitutes provide C0G/NP0 temperature coefficient with tighter tolerance (±1% or ±2%), reducing capacitance variation across the -55°C to 125°C operating range. Suitable for circuits requiring stable capacitance values.

For Higher Voltage Margin: Select KGM21NR72D102JT (KYOCERA AVX). This maintains X7R characteristics and ±5% tolerance while providing 200V rating in the same 0805 package, offering additional voltage headroom for the same footprint.

All recommended substitutes are ROHS3 compliant, MSL 1 (Unlimited), and maintain identical package dimensions and mounting characteristics.

Frequently Asked Questions (FAQ)

Q: Can I use a C0G/NP0 capacitor as a substitute for the X7R 08051C102JAT2M?

A: Yes, if your circuit design permits. C0G/NP0 capacitors provide superior temperature stability and lower capacitance drift. However, verify that the tighter tolerance (±1% or ±2%) and different temperature coefficient characteristics are compatible with your circuit requirements. C0G/NP0 parts are typically used in precision applications where capacitance stability is critical.

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

A: X7R provides ±15% capacitance change across -55°C to 125°C. C0G/NP0 provides ±30 ppm/°C (approximately ±0.3% across the same range). C0G/NP0 is preferred for precision circuits; X7R is suitable for general-purpose applications.

Q: Can I substitute a 200V rated capacitor for the 100V 08051C102JAT2M?

A: Yes. The KGM21NR72D102JT (200V X7R) is a direct upgrade substitute. Higher voltage rating provides additional safety margin without affecting circuit performance. The 1000 pF capacitance and ±5% tolerance remain identical.

Q: Are there thickness differences between substitute parts?

A: Yes. Thickness varies from 0.028" (0.70mm) to 0.039" (1.00mm) depending on manufacturer and series. Verify PCB layout clearance if height-constrained. The 0805 package footprint remains identical across all substitutes.

Q: Which substitute has the best inventory availability?

A: CL21B102JCANNNC (Samsung Electro-Mechanics) offers 122,177 pieces in stock, providing the highest availability for immediate procurement.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original 08051C102JAT2M specification.
