Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD03ZC102KAB2A is determined by the following criteria:

Fixed Parameters (Must Match):

• Capacitance: 1000 pF
• Temperature Coefficient: X7R
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C to 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage Rating: May be equal or higher than 10V
• Tolerance: May be ±10% or tighter (±5%)
• Manufacturer: KYOCERA AVX or KEMET
• Physical dimensions: Minor variations within 0603 package specification are acceptable

All substitute parts listed maintain identical capacitance, temperature coefficient, and package specifications while offering enhanced voltage ratings (50V, 100V, 200V) or improved tolerance specifications (±5% vs ±10%).

Parameter Comparison

Engineering Selection Recommendations

KYOCERA AVX Series (LD) Substitutes:

• LD031C102KAB2A (100V): Direct upgrade path within same manufacturer series. Maintains identical tolerance and package specifications. Recommended for applications requiring higher voltage margin. Significantly higher inventory availability (4577 pcs).
• LD032C102KAB2A (200V): Maximum voltage rating within KYOCERA AVX LD series. Suitable for high-voltage applications. Maintains all mechanical and electrical compatibility parameters.
• LD035C102KAB2A (50V): Mid-range voltage option within KYOCERA AVX LD series. Provides voltage headroom for standard applications. High inventory availability (4460 pcs).

KEMET Series (C0603C) Substitutes:

• C0603C102K1RAL7867 (100V, ±10%): Cross-manufacturer equivalent with identical electrical specifications to LD031C102KAB2A. Slightly reduced thickness (0.034" vs 0.035"). REACH Unaffected status differs from main part. Limited inventory (998 pcs).
• C0603C102K5RAL7867 (50V, ±10%): Cross-manufacturer equivalent with improved tolerance option available. Slightly reduced thickness. REACH Unaffected status. High inventory availability (7105 pcs).
• C0603C102J5RAL7867 (50V, ±5%): Tighter tolerance specification (±5%) for applications requiring improved capacitance accuracy. REACH Unaffected status. Highest inventory availability (5029 pcs).

All substitute parts maintain active product status and are available in Tape & Reel packaging. Selection should prioritize application voltage requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can LD03ZC102KAB2A be replaced with a higher voltage rated part? A: Yes. Higher voltage ratings (50V, 100V, 200V) are direct substitutes provided all other parameters remain constant: 1000 pF capacitance, X7R temperature coefficient, 0603 package, and ±10% tolerance (or tighter). Higher voltage ratings provide additional safety margin in the circuit.

Q: What is the difference between KYOCERA AVX LD series and KEMET C0603C series? A: Both manufacturers produce 1000 pF X7R 0603 ceramic capacitors with identical electrical performance. Physical dimensions are nearly identical (thickness varies by 0.001"). KEMET parts have REACH Unaffected status while KYOCERA AVX parts are REACH Affected. Both are RoHS non-compliant. Selection may depend on supply chain preference and inventory availability.

Q: Can I use C0603C102J5RAL7867 (±5% tolerance) instead of LD03ZC102KAB2A (±10% tolerance)? A: Yes. The ±5% tolerance is tighter and more stringent than ±10%, making it a compatible substitute. This provides improved capacitance accuracy for applications sensitive to tolerance variation. All other electrical and mechanical parameters are equivalent.

Q: Are there physical size differences between substitute parts? A: All parts conform to 0603 (1608 Metric) package specification. Maximum thickness varies slightly: KYOCERA AVX LD series is 0.035" (0.90mm) while KEMET C0603C series is 0.034" (0.87mm). These differences are within standard 0603 package tolerance and do not affect PCB assembly or circuit performance.

Q: Which substitute part has the best inventory availability? A: C0603C102K5RAL7867 (KEMET, 50V, ±10%) has the highest inventory at 7105 pcs, followed by C0603C102J5RAL7867 (KEMET, 50V, ±5%) at 5029 pcs. Within KYOCERA AVX LD series, LD031C102KAB2A (100V) offers 4577 pcs.

Q: What voltage rating should I select for my application? A: Select a voltage rating equal to or higher than your circuit's maximum operating voltage. For 10V applications, LD03ZC102KAB2A is sufficient. For improved margin, use 50V (LD035C102KAB2A or C0603C102K5RAL7867), 100V (LD031C102KAB2A or C0603C102K1RAL7867), or 200V (LD032C102KAB2A) rated parts.
