Electronic Components Supply Chain Dataset

Dataset Description

This dataset contains 791 electronic components collected from the Nexar API, enriched with supply chain risk analysis and supplier information. The dataset combines general electronic components and telecom-specific components, designed for supply chain transparency research, risk assessment, and component sourcing analysis.

Dataset Summary

• Total Components: 791
• Source: Nexar API (via Octopart)
• Collection Date: 2024
• Primary Use Case: Supply chain risk analysis, component sourcing, Chinese manufacturer identification

Dataset Structure

Each component entry includes:

• Basic Information:

  • mpn: Manufacturer Part Number (unique identifier)
  • manufacturer: Manufacturer nam6e
  • manufacturer_country: Country of origin
  • category: Component category
  • description: Component description

• Supply Chain Data:

  • suppliers: Array of suppliers with stock levels, prices, and SKUs
  • datasheets: Array of datasheet URLs
  • alternatives: Alternative part numbers

• Risk Analysis:

  • is_chinese: Boolean flag indicating Chinese origin
  • confidence_score: Confidence in origin classification (0-1)
  • risk_score: Supply chain risk score (0-1)
  • risk_factors: Array of identified risk factors

• Raw Data:

  • nexar_data: Complete raw data from Nexar API

Dataset Statistics

• Top Manufacturers: Analog Devices (195), Texas Instruments (184), STMicroelectronics (100), Espressif Systems (63), GigaDevice (48)
• Datasheet Coverage: 81.2% (642/791 components)
• Chinese Components: 14 (1.8%) - Telecom-focused dataset with Western manufacturers
• Supplier Coverage: 97.6% (772/791 components have supplier information)
• Supplier Diversity: Multiple suppliers per component (DigiKey, Mouser, TME, etc.)

Use Cases

1. Supply Chain Risk Assessment: Identify components with high supply chain risks
2. Component Sourcing: Find alternative suppliers and pricing information
3. Research: Analyze electronic component market and supply chain dependencies
4. BOM Analysis: Assess Bill of Materials for supply chain vulnerabilities

Data Collection

The data was collected using the Nexar API (Octopart) from two sources:

1. General Components (404 components): Broad electronic component collection
2. Telecom Components (387 components): Focused on telecom/photonics components

Important: This dataset is for research and educational purposes only. The underlying component data is sourced from Octopart/Nexar. Users must comply with Octopart's Terms & Conditions when using this dataset.

Data was enriched with:

• Manufacturer country identification
• Chinese origin classification
• Supply chain risk scoring
• Supplier aggregation
• Datasheet links

Limitations

• Dataset size: 791 components (curated dataset, not exhaustive)
• Price and stock data may be outdated
• Risk scores are estimates based on origin and supply chain factors
• Telecom dataset has lower Chinese component percentage (1.8%) due to focus on Western manufacturers
• Some components may have incomplete supplier information
