Substitute Part Grouping Explanation

Substitute parts are classified based on the following substitution criteria:

Parametric Equivalent: Parts matching all critical electrical parameters (capacitance, tolerance, voltage rating, temperature coefficient) and mechanical specifications (package, dimensions, mounting type) with identical or superior performance characteristics.

Upgrade Parts: Parts offering improved specifications (tighter tolerance, higher voltage rating, or enhanced temperature coefficient) while maintaining the same capacitance value, package, and mounting compatibility. These parts provide enhanced reliability margins and are direct functional upgrades.

Direct Equivalents: Parts from alternative manufacturers meeting identical electrical and mechanical specifications, enabling cross-manufacturer sourcing without design modification.

The following parameters determine substitution validity:

Capacitance value: 0.082 µF (fixed)
Package / Case: 1206 (3216 Metric) (fixed)
Mounting Type: Surface Mount, MLCC (fixed)
Operating Temperature Range: -55°C to 125°C (fixed)
Voltage Rating: 50V minimum (equal or higher acceptable)
Tolerance: ±10% or tighter (tighter tolerance acceptable)

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 50V specification?

A: Yes. Parts rated for 100V (C1206C823K1RAC7800) or 250V (C1206C823KARAC7800) are direct upgrades. Higher voltage ratings provide additional safety margin and are electrically compatible with 50V circuit requirements. No design modification is required.

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

A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% variation per °C. C0G/NP0 is suitable for precision timing, filtering, and frequency-critical applications. Both are acceptable substitutes; selection depends on application requirements.

Q: Are tighter tolerance parts (±5%) direct substitutes for ±10% parts?

A: Yes. Tighter tolerance parts (±5%) are direct upgrades and fully compatible. They provide improved capacitance accuracy without design modification. Parts KGM31BR71H823JT, C1206C823J5RAC7800, and C1206C823J5GAC7800 offer this upgrade.

Q: Does package thickness affect substitution compatibility?

A: Package thickness may impact board layout and component clearance. The original part is 0.037" (0.94mm). KEMET parts are typically 0.035" (0.88mm), offering improved space efficiency. YAGEO CC1206KRX7R9BB823 is 0.075" (1.90mm) and requires verification of board clearance before substitution.

Q: Can I substitute parts from different manufacturers?

A: Yes. KEMET (C1206C823K5RAC7800) and YAGEO (CC1206KRX7R9BB823) parts meet identical electrical and mechanical specifications. All parts are ROHS3 compliant and carry equivalent certifications. Cross-manufacturer substitution is valid for this product category.

Q: What inventory considerations should guide part selection?

A: KGM31BR71H823JT (KYOCERA AVX) offers the highest inventory (12882 Pcs), followed by C1206C823KARAC7800 (16119 Pcs) and C1206C823K1RAC7800 (13954 Pcs). Original part 12065C823KAT2P has 907 Pcs available. Inventory levels may influence lead time and cost considerations.
