Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LD02YA101JAB2A are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 100 pF (exact match required)
• Temperature Coefficient: C0G, NP0 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Mechanical Parameters (Must Match):

• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Moisture Sensitivity Level: 1 (Unlimited)

Parameters Allowed to Differ:

• Voltage Rating: Substitutes rated at 50V are acceptable (higher voltage rating provides additional design margin)
• Tolerance: Substitutes with ±1% tolerance are acceptable (tighter tolerance is compatible)
• Manufacturer: KYOCERA AVX or KEMET

All three substitute parts meet these criteria and are direct functional replacements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products suitable for direct replacement of the LD02YA101JAB2A. Selection should be based on the following factors:

KYOCERA AVX LD025A101FAB2A: Offers the tightest tolerance specification (±1%) while maintaining the same manufacturer lineage. Rated at 50V, providing increased voltage margin. REACH Affected status matches the original part.

KYOCERA AVX LD025A101JAB2A: Maintains identical tolerance (±5%) to the original part while upgrading voltage rating to 50V. Largest inventory availability (33,538 pcs) among KYOCERA AVX options. REACH Affected status matches the original part.

KEMET C0402C101J5GAL7867: Cross-manufacturer alternative with 50V rating and ±5% tolerance. Highest inventory availability (60,042 pcs). REACH Unaffected status may be advantageous for certain supply chain requirements. Thickness specification is 0.022" (0.55mm), within acceptable tolerance.

All parts share identical electrical performance characteristics, mechanical compatibility, and environmental operating ranges. Selection among substitutes depends on tolerance requirements, voltage margin preferences, manufacturer preference, and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can LD025A101FAB2A and LD025A101JAB2A be used interchangeably with LD02YA101JAB2A?

A: Yes. Both parts maintain identical capacitance (100 pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and package dimensions (0402). The 50V voltage rating is a direct upgrade from 16V, providing additional design margin without affecting circuit performance.

Q: What is the difference between LD025A101FAB2A and LD025A101JAB2A?

A: The primary difference is tolerance specification. LD025A101FAB2A offers ±1% tolerance, while LD025A101JAB2A offers ±5% tolerance. Both are rated at 50V and are otherwise electrically and mechanically identical. Selection depends on tolerance requirements for the application.

Q: Is the KEMET C0402C101J5GAL7867 a suitable replacement?

A: Yes. The KEMET part meets all electrical and mechanical requirements: 100 pF capacitance, C0G/NP0 temperature coefficient, 50V rating, 0402 package, and -55°C ~ 125°C operating range. Thickness is 0.022" (0.55mm), which is within acceptable tolerance of the original 0.56mm specification.

Q: Does upgrading from 16V to 50V affect circuit design?

A: No. A higher voltage rating does not affect circuit performance when the applied voltage remains at or below the original 16V specification. The 50V-rated substitutes provide additional safety margin and reliability.

Q: Are there any compliance differences between substitutes?

A: All parts are RoHS non-compliant. KYOCERA AVX parts (LD025A101FAB2A and LD025A101JAB2A) are REACH Affected, matching the original part. The KEMET C0402C101J5GAL7867 is REACH Unaffected, which may be relevant for specific supply chain or regulatory requirements.

Q: Can these parts be used in high-frequency applications?

A: All parts feature C0G/NP0 temperature coefficient and identical package geometry, making them suitable for general purpose applications across the specified temperature range. Application-specific performance characteristics depend on circuit design requirements.
