Substitute Part Grouping Explanation

Substitution for the C0603C102J5RAC is determined by strict equivalence of electrical and mechanical parameters. The following criteria establish valid substitutes:

Primary Substitution Criteria:

• Capacitance value: 1000 pF (exact match required)
• Tolerance: ±5% (or tighter tolerance acceptable)
• Voltage rating: 50V minimum (higher voltage ratings acceptable as upgrades)
• Temperature coefficient: X7R (or equivalent stability)
• Package: 0603 (1608 Metric) surface mount
• Operating temperature: -55°C to 125°C minimum
• Mounting type: Surface Mount, MLCC

Substitution Categories:

Direct Equivalent: Parts with identical electrical specifications and 50V voltage rating, differing only in manufacturer and packaging format.

Upgrade Substitute: Parts with identical capacitance and tolerance but higher voltage rating (100V), providing enhanced design margin while maintaining all other specifications.

Similar Alternative: Parts with identical capacitance and voltage rating but different temperature coefficient (C0G/NP0 instead of X7R), offering improved temperature stability at the cost of different dielectric characteristics.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

The C0603C102J5RAC7867 manufactured by KEMET is the direct equivalent substitute. This part maintains all electrical parameters (1000 pF, ±5%, 50V, X7R) and mechanical specifications (0603 package, -55°C to 125°C operating range) of the original CDE component. The KEMET part is currently in active production status with substantial inventory availability (213,775 pcs), ensuring long-term supply continuity. Both parts are ROHS3 compliant and carry MSL 1 rating. The KEMET substitute is available in Tape & Reel packaging format, suitable for automated assembly processes.

For Enhanced Voltage Margin (Upgrade Path):

The 06031C102JA76A manufactured by KYOCERA AVX provides an upgrade substitute with doubled voltage rating (100V) while maintaining identical capacitance (1000 pF), tolerance (±5%), and X7R temperature coefficient. This part is suitable for applications requiring additional design margin or operating in higher voltage environments. The upgrade substitute is in active production status with 702 pcs in stock. Note that this part carries RoHS non-compliant status and REACH Affected designation, which may impact procurement for regulated applications.

For Improved Temperature Stability (Alternative Dielectric):

The 06035A102FA16A manufactured by KYOCERA AVX offers tighter tolerance (±1% versus ±5%) with C0G/NP0 temperature coefficient, providing superior temperature stability compared to X7R. This alternative maintains the 50V voltage rating and 0603 package format. The C0G/NP0 dielectric exhibits minimal capacitance variation across temperature extremes, making this part suitable for precision timing and filtering circuits. This part is in active production with 1,179 pcs available. RoHS non-compliant and REACH Affected status applies.

Frequently Asked Questions (FAQ)

Q: Can the KEMET C0603C102J5RAC7867 be used as a direct replacement for the obsolete CDE C0603C102J5RAC?

A: Yes. The KEMET part is a direct equivalent with identical electrical specifications (1000 pF, ±5%, 50V, X7R) and mechanical package (0603 surface mount). Both parts share the same operating temperature range (-55°C to 125°C), moisture sensitivity level (MSL 1), and RoHS3 compliance status. The parts are electrically and mechanically interchangeable.

Q: What is the difference between the 50V and 100V rated versions?

A: The 06031C102JA76A provides 100V voltage rating compared to the original 50V specification. Both maintain identical capacitance (1000 pF), tolerance (±5%), and X7R temperature coefficient. The higher voltage rating provides additional design margin and allows operation in higher voltage circuits. The 100V part is physically compatible with the 0603 package footprint.

Q: Why would I select the C0G/NP0 alternative over the X7R substitute?

A: The C0G/NP0 temperature coefficient (06035A102FA16A) provides superior temperature stability with ±1% tolerance compared to ±5% for X7R parts. C0G/NP0 dielectrics exhibit minimal capacitance drift across the -55°C to 125°C operating range, making them suitable for precision applications such as timing circuits, filters, and reference networks where temperature-induced capacitance variation must be minimized. X7R dielectrics are acceptable for general-purpose bypass and decoupling where moderate capacitance variation is tolerable.

Q: Are there packaging format differences between substitutes?

A: The KEMET C0603C102J5RAC7867 is supplied in Tape & Reel (TR) format for automated assembly. The KYOCERA AVX parts do not specify packaging format in the provided data. All three substitute options use identical 0603 (1608 Metric) surface mount package with compatible PCB footprints and reflow soldering processes.

Q: What compliance considerations apply to substitute selection?

A: The KEMET direct equivalent (C0603C102J5RAC7867) maintains ROHS3 compliance matching the original part. Both KYOCERA AVX substitutes are marked as RoHS non-compliant and REACH Affected. For applications requiring RoHS3 compliance, the KEMET substitute is the appropriate selection. For applications without RoHS restrictions, all three substitutes are technically valid based on electrical and mechanical parameters.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts carry MSL 1 (Unlimited) rating, identical to the original CDE part. MSL 1 indicates unlimited shelf life without moisture baking requirements, simplifying inventory management and assembly processes.
