Why is it required that the components provided by kitting suppliers must be DC within 2 years?

Selecting component lots within two years mainly serves four purposes:

Quality & Reliability
- Warranty coverage: lots remain within the manufacturer’s warranty period under specified storage/transport conditions.
- Reduced degradation: shorter storage time minimizes moisture ingress and lead oxidation, lowering soldering defects and field failures.
Technical Support & After-Sales Service
- Traceability: newer lots are easier to track, ensuring faster OEM technical support.
- Recall readiness: defects can be quickly isolated and recalled, limiting liability.
Performance Consistency & Optimization
- Process uniformity: production parameters are more consistent, yielding stable electrical characteristics.
- Latest revisions: devices are more likely to incorporate bug fixes and performance tweaks released within the past two years.
Market Practice & Supply-Chain Efficiency
- Industry norm: most industrial and commercial customers mandate <2-year lots to uphold product quality and market reputation.
- Availability: fresher inventory enjoys better market liquidity, enabling faster procurement and shorter lead times.

In conclusion, limiting component lots to within two years is a standard requirement for our component kitting suppliers. This policy balances quality assurance, technical support, product consistency and market expectations, minimizing quality risks and enhancing both stability and competitiveness.
