Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters:

Primary Matching Criteria:

Capacitance: 1000 pF (exact match required)
Voltage Rating: 100V minimum (equal or higher acceptable)
Package: 0805 (2012 Metric) surface mount
Temperature Coefficient: X7R (same dielectric type)
Tolerance: ±5% (same or tighter tolerance acceptable)

Grouping Categories:

Category 1: Direct Equivalents (X7R, ±5%, 100V) Parts with identical electrical specifications and X7R dielectric. These are pin-compatible replacements with no circuit redesign required.

Category 2: Upgraded Specifications (C0G/NP0, ±1% or ±2%, 100V) Parts with superior temperature stability (C0G/NP0 dielectric) and tighter tolerance (±1% or ±2%). These provide enhanced performance in temperature-sensitive applications while maintaining 100V rating.

Category 3: Higher Voltage Rating (X7R, ±5%, 200V) Parts with elevated voltage rating (200V) and X7R dielectric. These provide additional voltage margin and are suitable for applications requiring higher voltage headroom.

Engineering Selection Recommendations

For Direct Replacement (No Circuit Redesign): Select from X7R dielectric parts with ±5% tolerance and 100V rating: KGM21NR72A102JM, KGM21NR72A102JT, C0805C102J1RAC7800, CC0805JRX7R0BB102, or CL21B102JCANNNC. All are Active status, ROHS3 compliant, and MSL 1 rated. These maintain identical electrical performance and circuit behavior.

For Enhanced Temperature Stability: Select C0G/NP0 dielectric parts (KGM21BCG2A102FT, KGM21BCG2A102GT, C0805C102F1GAC7800, C0805C102G1GAC7800) when applications require superior temperature coefficient performance. These offer ±1% or ±2% tolerance with improved stability across the -55°C to 125°C operating range.

For Higher Voltage Margin: Select KGM21NR72D102JT (200V rating) when circuit design requires additional voltage headroom or when operating near maximum voltage limits of the original 100V specification.

Compliance Verification: All listed substitutes are Active status, ROHS3 compliant, and MSL 1 rated, matching the original part's regulatory and environmental certifications.

Frequently Asked Questions (FAQ)

Q: Can I use a C0G/NP0 dielectric part as a substitute for the X7R original? A: Yes. C0G/NP0 parts (KGM21BCG2A102FT, KGM21BCG2A102GT, C0805C102F1GAC7800, C0805C102G1GAC7800) are functionally compatible. They provide superior temperature stability and tighter tolerance, making them suitable upgrades for temperature-sensitive circuits.

Q: What is the difference between the KYOCERA AVX KGM21NR72A102JM and KGM21NR72A102JT? A: Both parts are identical in electrical specifications (1000 pF, ±5%, 100V, X7R, 0805). The difference is in packaging designation (JM vs. JT). Both are suitable direct replacements.

Q: Can I use the 200V rated part (KGM21NR72D102JT) in place of the 100V original? A: Yes. The 200V rated part is electrically compatible and provides additional voltage margin. It is a valid substitute for applications where higher voltage rating is acceptable or beneficial.

Q: Are there thickness variations among substitute parts? A: Yes. Thickness ranges from 0.028" (0.70mm) to 0.039" (1.00mm). Verify PCB layout and component clearance requirements before substitution if board space is constrained.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All listed substitutes are MSL 1 (Unlimited), matching the original part's moisture sensitivity rating.

Q: Which substitute offers the best availability? A: CL21B102JCANNNC (Samsung Electro-Mechanics) has the highest inventory at 122,177 pieces. KGM21NR72A102JT (KYOCERA AVX) has 47,340 pieces available.
