LD031A331JAB2A Equivalent & Substitute Parts Reference

Part Overview

The LD031A331JAB2A is a 330 pF ±5% 100V ceramic capacitor manufactured by KYOCERA AVX in the LD series. This surface mount multilayer ceramic capacitor (MLCC) features C0G/NP0 temperature coefficient characteristics and is housed in a 0603 (1608 Metric) package. The component is currently in active production status with 4486 pieces available in inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same capacitance value, voltage rating, tolerance, temperature coefficient, package size, and mounting type. Alternative models may be required due to packaging format availability, compliance certifications, or supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

LD031A331JAB2A (Original Part)

• Use when Tape & Reel packaging is required for automated assembly processes
• Suitable for applications where RoHS non-compliance is acceptable
• General purpose applications with no automotive qualification requirement

KAM15ACG2A331JT (Upgrade Substitute)

• Recommended for automotive applications requiring AEC-Q200 certification
• Provides ROHS3 compliance and REACH unaffected status
• Available in Cut Tape and Digi-Reel packaging formats
• Higher inventory availability (8976 pieces) supports production continuity

KGM15ACG2A331JT (Parametric Equivalent)

• Recommended for general purpose applications requiring ROHS3 compliance
• Highest inventory availability (21470 pieces) ensures supply chain reliability
• Tape & Reel packaging maintains compatibility with existing assembly equipment
• KGM series designation indicates C0G temperature coefficient specialization

All three parts maintain identical electrical performance and mechanical compatibility. Selection should be based on packaging format requirements, compliance certifications needed for the end application, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can KAM15ACG2A331JT replace LD031A331JAB2A in automotive applications? A: Yes. KAM15ACG2A331JT is qualified to AEC-Q200 automotive standards and maintains all electrical and mechanical parameters of the original part. It is suitable for automotive circuit designs.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) and Digi-Reel packaging provide smaller quantities on cut tape segments, suitable for lower-volume production or manual assembly processes.

Q: Are all three parts electrically interchangeable? A: Yes. LD031A331JAB2A, KAM15ACG2A331JT, and KGM15ACG2A331JT are electrically identical with 330 pF capacitance, ±5% tolerance, 100V rating, and C0G/NP0 temperature coefficient. They are mechanically compatible in 0603 (1608 Metric) package footprints.

Q: What does RoHS3 compliance mean? A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive 3 requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. KAM15ACG2A331JT and KGM15ACG2A331JT are ROHS3 compliant; LD031A331JAB2A is not.

Q: Does REACH unaffected status affect component performance? A: No. REACH unaffected status indicates the component does not contain substances of very high concern (SVHC) listed under REACH regulations. This is a regulatory compliance designation and does not impact electrical or mechanical performance.

Q: Which part should I select for new designs? A: For new designs, KGM15ACG2A331JT is recommended due to highest inventory availability (21470 pieces), ROHS3 compliance, and REACH unaffected status. For automotive applications, KAM15ACG2A331JT provides AEC-Q200 qualification.

Q: Can I mix different part numbers in the same assembly? A: Yes. All three parts are mechanically and electrically compatible and can be used interchangeably in the same circuit design without performance degradation.
