Key Parameters

Substitute Part Grouping Explanation

Substitution for LD033C102KAB2C is determined by the following critical parameters:

• Capacitance: Must be 1000 pF (exact match required)
• Tolerance: ±10% or tighter (±5% acceptable as upgrade)
• Temperature Coefficient: X7R (mandatory for stable performance across operating range)
• Package / Case: 0603 (1608 Metric) surface mount (physical and electrical compatibility)
• Operating Temperature: -55°C ~ 125°C (minimum requirement)
• Voltage Rating: Equal to or greater than 25V (higher voltage ratings provide design margin)

Substitute parts are grouped into two categories:

KYOCERA AVX Series (LD): Parts LD031C102KAB2A, LD032C102KAB2A, and LD035C102KAB2A maintain identical physical dimensions, temperature coefficient, and tolerance while offering higher voltage ratings (50V, 100V, 200V respectively).

KEMET Series (C0603C): Parts C0603C102J5RAL7867, C0603C102K5RAL7867, and C0603C102K1RAL7867 provide equivalent electrical performance with matching package and operating temperature range. C0603C102J5RAL7867 offers tighter ±5% tolerance. All KEMET parts have slightly different physical dimensions (0.031" width vs. 0.032" for KYOCERA AVX).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and are electrically and mechanically compatible with LD033C102KAB2C within the specified parameters.

KYOCERA AVX LD Series substitutes (LD031C102KAB2A, LD032C102KAB2A, LD035C102KAB2A) provide direct form-fit-function replacement with identical physical dimensions and REACH Affected status matching the original part. Selection among these depends on required voltage margin: LD035C102KAB2A (50V) for moderate margin, LD031C102KAB2A (100V) for higher margin, or LD032C102KAB2A (200V) for maximum margin.

KEMET C0603C Series substitutes (C0603C102J5RAL7867, C0603C102K5RAL7867, C0603C102K1RAL7867) offer REACH Unaffected status and are suitable where regulatory compliance differs from the original part. Physical dimensions are within 0.001" tolerance of the original. C0603C102J5RAL7867 provides tighter ±5% tolerance for applications requiring improved capacitance stability.

All parts share MSL 1 (Unlimited) moisture sensitivity, eliminating bake-out requirements. Voltage ratings of all substitutes equal or exceed the original 25V specification.

Frequently Asked Questions (FAQ)

Q: Can LD031C102KAB2A replace LD033C102KAB2C directly?

A: Yes. Both parts have identical capacitance (1000 pF), tolerance (±10%), temperature coefficient (X7R), package (0603), and operating temperature range (-55°C ~ 125°C). LD031C102KAB2A has a higher voltage rating (100V vs. 25V), which provides additional design margin without affecting circuit performance.

Q: What is the difference between KYOCERA AVX and KEMET substitutes?

A: KYOCERA AVX LD series parts maintain identical physical dimensions (0.063" x 0.032" x 0.035" max) and REACH Affected status. KEMET C0603C series parts have slightly smaller width (0.031" vs. 0.032") and thickness (0.034" vs. 0.035" max) with REACH Unaffected status. Both are mechanically compatible with standard 0603 footprints.

Q: Is C0603C102J5RAL7867 better than other substitutes?

A: C0603C102J5RAL7867 offers ±5% tolerance compared to ±10% for other parts, providing tighter capacitance control. Selection depends on application requirements for capacitance accuracy. All other electrical and mechanical parameters are equivalent to C0603C102K5RAL7867.

Q: Can I use a 200V rated capacitor (LD032C102KAB2A) in place of the 25V original?

A: Yes. Higher voltage ratings are electrically compatible and provide increased design margin. Physical dimensions remain identical. No circuit modifications are required.

Q: Are all substitute parts MSL 1?

A: Yes. All listed substitutes have MSL 1 (Unlimited) moisture sensitivity level, matching the original part. No special moisture control or bake-out procedures are required.

Q: What is the impact of REACH status differences?

A: KYOCERA AVX parts are REACH Affected; KEMET parts are REACH Unaffected. Selection depends on regulatory requirements for your application and supply chain. Electrical and mechanical performance are unaffected by REACH status.
