Key Parameters

Substitute Part Grouping Explanation

Substitution of the LD033C104JAB4A is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±5% (electrical performance specification)
• Voltage rating: 25V (minimum required rating)
• Temperature coefficient: X7R (temperature stability characteristic)
• Package: 0603 (1608 Metric) (physical and electrical footprint compatibility)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)
• Moisture sensitivity: MSL 1 (handling and storage requirements)

The substitute part C0603C104J3RAL7867 manufactured by KEMET meets all these criteria, enabling direct functional and physical replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the LD033C104JAB4A and C0603C104J3RAL7867 are Active product status components with identical electrical specifications and compatible physical dimensions. The KEMET substitute provides 6160 pieces in stock inventory compared to 1165 pieces for the KYOCERA AVX original part, offering improved supply availability. Both components carry EAR99 ECCN classification and identical HTSUS codes. The KEMET part is REACH Unaffected while the KYOCERA AVX part is REACH Affected; however, both are RoHS non-compliant. Physical dimensions show negligible variation (width difference of 0.01mm, thickness difference of 0.03mm) within standard manufacturing tolerances for 0603 package components. Selection between these parts should be based on procurement lead time, cost considerations, and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can C0603C104J3RAL7867 be used as a direct replacement for LD033C104JAB4A?

A: Yes. Both parts share identical electrical specifications (0.1 µF, ±5%, 25V, X7R) and are packaged in 0603 (1608 Metric) surface mount format. Physical dimensions are within standard manufacturing tolerances for this package class.

Q: Are there any compliance differences between these parts?

A: Both parts carry EAR99 ECCN and 8532.24.0020 HTSUS classifications. The KEMET part is REACH Unaffected while the KYOCERA AVX part is REACH Affected. Both are RoHS non-compliant. Compliance requirements should be verified against your specific application and regional regulations.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates a temperature coefficient of ±15% over the -55°C to 125°C operating range. This specification ensures stable capacitance performance across the full operating temperature range for both parts, making them suitable for general purpose and bypass/decoupling applications.

Q: Do the minor dimensional differences affect PCB layout?

A: No. The width difference of 0.01mm (1.60mm vs 1.60mm nominal) and thickness difference of 0.03mm (0.90mm vs 0.87mm) are within standard manufacturing tolerances for 0603 package components and do not require PCB layout modifications.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture bake requirements. Both parts can be stored and handled under standard conditions without special moisture control procedures.
