Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LD02YC472KAB2A is determined by the following critical parameters that must remain constant:

• Capacitance Value: 4700 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowed Variation Parameter:

• Voltage - Rated: May be increased from 16V to higher ratings (50V or greater) while maintaining all other specifications. Higher voltage ratings provide enhanced design margin and are electrically compatible in applications designed for 16V operation.

The substitute part LD025C472KAB2A meets all constant parameter requirements while providing an upgraded voltage rating of 50V, making it suitable for applications requiring improved voltage headroom or higher reliability margins.

Parameter Comparison

Engineering Selection Recommendations

Both LD02YC472KAB2A and LD025C472KAB2A are Active status products from KYOCERA AVX with identical physical dimensions, electrical characteristics, and environmental specifications. Selection between these parts depends on application voltage requirements:

LD02YC472KAB2A (16V Rating): Select for applications with circuit voltage requirements at or below 16V where the rated voltage specification directly matches the design specification.

LD025C472KAB2A (50V Rating): Select for applications requiring voltage margin above 16V, applications with potential voltage transients, or designs where higher voltage rated components are preferred for reliability enhancement. The 50V rating provides 3.125x voltage derating factor relative to the 16V specification.

Both parts carry identical RoHS non-compliant and REACH Affected compliance status. Inventory availability favors LD025C472KAB2A with 10967 units in stock compared to 883 units for the main part.

Frequently Asked Questions (FAQ)

Q: Can LD025C472KAB2A replace LD02YC472KAB2A in a 16V circuit?

A: Yes. The LD025C472KAB2A is electrically and mechanically compatible. The 50V voltage rating exceeds the 16V circuit requirement, providing additional design margin. Physical dimensions, capacitance value, tolerance, temperature coefficient, and package form factor are identical.

Q: What is the primary difference between these two parts?

A: The sole difference is the voltage rating: LD02YC472KAB2A is rated 16V while LD025C472KAB2A is rated 50V. All other electrical and mechanical parameters are identical.

Q: Are there any package or mounting differences?

A: No. Both parts use the 0402 (1005 Metric) package with identical physical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness of 0.022" (0.56mm). Both are surface mount MLCCs with identical mounting requirements.

Q: What does the X7R temperature coefficient indicate?

A: X7R indicates the capacitance change over the operating temperature range of -55°C to 125°C. Both parts maintain this specification, ensuring stable capacitance performance across the full temperature range.

Q: Is moisture sensitivity a concern for these parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard handling and storage practices are sufficient.

Q: Can LD02YC472KAB2A be used in applications designed for 50V?

A: No. The LD02YC472KAB2A is rated for maximum 16V operation. Use LD025C472KAB2A for applications requiring 50V rated components.
