LD02YA101FAB2A Equivalent & Substitute Parts

Part Overview

The LD02YA101FAB2A is a 100 pF ceramic capacitor manufactured by KYOCERA AVX, rated at 16V with C0G/NP0 temperature coefficient and ±1% tolerance. This surface mount multilayer ceramic capacitor (MLCC) in 0402 package is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with 714 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this component category.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LD02YA101FAB2A is determined by the following criteria:

Capacitance value must remain 100 pF with ±1% tolerance to maintain circuit performance. Temperature coefficient must be C0G/NP0 to ensure stable operation across the full operating temperature range of -55°C to 125°C. Package and mounting type must be identical: 0402 (1005 Metric) surface mount configuration. Moisture sensitivity level must be MSL 1 or better. Voltage rating may be equal to or higher than the original 16V specification, as higher voltage ratings provide backward compatibility in circuits designed for lower voltage operation.

The substitute part LD025A101FAB2A meets all substitution criteria with an upgraded voltage rating of 50V, maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The LD025A101FAB2A serves as a direct substitute for the LD02YA101FAB2A with the advantage of increased voltage rating (50V versus 16V). Both parts are manufactured by KYOCERA AVX within the same LD series and maintain identical electrical characteristics for capacitance, tolerance, and temperature coefficient. Both parts carry the same regulatory status: RoHS non-compliant, REACH Affected, and ECCN EAR99 classification. The substitute part is suitable for applications where the original 16V rating is adequate, as the higher voltage specification provides additional design margin without affecting circuit performance. Both parts are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can LD025A101FAB2A replace LD02YA101FAB2A in existing designs?

A: Yes. The substitute part maintains identical capacitance (100 pF), tolerance (±1%), temperature coefficient (C0G/NP0), package (0402), and physical dimensions. The 50V rating is compatible with circuits designed for 16V operation.

Q: Are there any physical differences between these parts?

A: No. Both parts share identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum thickness (0.022", 0.56mm). They are mechanically interchangeable in PCB layouts.

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

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the difference between these two parts?

A: The primary difference is the voltage rating: LD02YA101FAB2A is rated 16V, while LD025A101FAB2A is rated 50V. All other specifications remain identical.

Q: Are regulatory certifications identical?

A: Yes. Both parts share the same RoHS non-compliant status, REACH Affected designation, ECCN EAR99 classification, and HTSUS code 8532.24.0020.
