Key Parameters

Substitute Part Grouping Explanation

Direct electrical and mechanical substitutes for the C1206C103K1RAC are determined by strict equivalence across the following parameters:

Required Matching Parameters:

• Capacitance: 10000 pF
• Tolerance: ±10%
• Voltage Rating: 100V (minimum)
• Temperature Coefficient: X7R
• Package / Case: 1206 (3216 Metric)
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Surface Mount, MLCC

Substitution Categories:

Direct Equivalents (Identical Specifications): Parts meeting all electrical and mechanical requirements with 100V rated voltage.

Upgraded Alternatives (Higher Voltage Rating): Parts with identical capacitance, tolerance, and package but rated at higher voltage (200V), providing design margin without electrical compromise.

Parameter Comparison

Engineering Selection Recommendations

12061C103KAT9A (KYOCERA AVX): Direct equivalent meeting all electrical specifications with ROHS3 compliance. Optimal for new designs and legacy replacements with highest inventory availability (747 pcs). Lowest physical thickness (0.037") supports space-constrained applications.

C1206C103K1RAC7800 (KEMET): Direct equivalent with ROHS3 compliance and active product status. Largest inventory (2785 pcs) ensures supply chain continuity. Thickness of 0.035" provides flexibility in PCB assembly processes. Suitable for bypass and decoupling applications.

C1206N103K1XMH (KEMET): Direct equivalent qualified to MIL-PRF-55681 standard (CDR32 series) for high-reliability applications. RoHS non-compliant; selection limited to legacy systems or requirements explicitly waiving RoHS certification. Maximum thickness (0.063") identical to original part.

12062C103KAT9A (KYOCERA AVX): Upgraded substitute with 200V rated voltage while maintaining identical capacitance, tolerance, and package. Selection appropriate for designs requiring increased voltage margin. ROHS3 compliant with active product status.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete C1206C103K1RAC with any of these parts directly on the PCB?

A: Yes. All listed direct equivalents (12061C103KAT9A, C1206C103K1RAC7800, and C1206N103K1XMH) are electrically and mechanically interchangeable with identical capacitance (10000 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), and 1206 package dimensions. Thickness variations (0.035" to 0.063") remain within PCB assembly tolerances.

Q: What is the difference between the direct equivalents and the upgraded part 12062C103KAT9A?

A: The 12062C103KAT9A has an identical capacitance, tolerance, and package but is rated at 200V instead of 100V. It provides increased voltage margin in applications where the original 100V rating is sufficient but additional headroom is beneficial. All other electrical and mechanical parameters remain equivalent.

Q: Which substitute should I choose for RoHS compliance?

A: All substitutes except C1206N103K1XMH are ROHS3 compliant. Select 12061C103KAT9A, C1206C103K1RAC7800, or 12062C103KAT9A for designs requiring RoHS certification.

Q: Does the thickness variation between substitutes affect PCB assembly?

A: Physical thickness ranges from 0.035" (C1206C103K1RAC7800) to 0.063" (C1206N103K1XMH). All variations fall within standard MLCC 1206 package tolerances and present no assembly complications. Select based on application requirements rather than thickness.

Q: What applications are these capacitors suitable for?

A: Direct equivalents support general-purpose applications. C1206C103K1RAC7800 is specifically qualified for bypass and decoupling circuits. C1206N103K1XMH is qualified for high-reliability applications under MIL-PRF-55681 standard.

Q: Are these parts subject to lead-time constraints?

A: C1206C103K1RAC7800 has the highest inventory (2785 pcs), followed by 12062C103KAT9A (755 pcs) and 12061C103KAT9A (747 pcs). C1206N103K1XMH has the lowest inventory (1114 pcs) among active substitutes.
