Key Parameters

Substitute Part Grouping Explanation

Substitution of the LD02YA151FAB2A is determined by strict equivalence in the following parameters:

• Capacitance Value: 150 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: C0G/NP0 (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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part LD025A151FAB2A meets all these criteria. The voltage rating of the substitute part (50V) exceeds the original specification (16V), which is permissible in substitution scenarios as higher voltage ratings provide additional design margin without affecting circuit performance in applications rated for 16V operation.

Parameter Comparison

Engineering Selection Recommendations

Both the LD02YA151FAB2A and LD025A151FAB2A are active production parts from KYOCERA AVX with identical electrical characteristics in capacitance, tolerance, and temperature coefficient. The substitute part LD025A151FAB2A provides equivalent functionality with an elevated voltage rating of 50V compared to the 16V specification of the main part. This voltage elevation does not introduce any performance degradation in circuits designed for 16V operation and may provide additional reliability margin in applications subject to transient voltage conditions. Both parts share identical physical dimensions, mounting characteristics, and moisture sensitivity ratings, ensuring direct mechanical and thermal compatibility on printed circuit boards. Selection between these parts may be based on inventory availability, supply chain considerations, or design margin requirements.

Frequently Asked Questions (FAQ)

Q: Can LD025A151FAB2A be used as a direct replacement for LD02YA151FAB2A?

A: Yes. The LD025A151FAB2A is electrically and mechanically compatible with LD02YA151FAB2A. Both parts have identical capacitance (150 pF), tolerance (±1%), temperature coefficient (C0G/NP0), package dimensions (0402), and operating temperature range (-55°C to 125°C). The higher voltage rating (50V vs. 16V) of the substitute part does not affect compatibility in 16V-rated applications.

Q: What is the significance of the voltage rating difference?

A: The LD025A151FAB2A operates at 50V maximum, while the LD02YA151FAB2A is rated for 16V maximum. In applications where the circuit voltage does not exceed 16V, the higher voltage rating of the substitute part provides additional design margin and does not alter electrical performance. The substitute part is suitable for any application where the original part was specified.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0402 (1005 Metric) form factor with identical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness of 0.022" (0.56mm). They are mechanically interchangeable on printed circuit boards without layout modifications.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both LD02YA151FAB2A and LD025A151FAB2A have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: Are there any compliance or certification differences?

A: Both parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8532.24.0020. No compliance differences exist between the main part and substitute.
