Spectra Products

Supply Chain Resilience (SCR)

Supply Chain Resilience is a Spectra product designed for organizations that purchase components, such as OEMs and EMSs. By providing daily supply chain indicators for millions of parts based on tens of millions of daily data points, SCR improves revenue predictability and helps organizations shift from reactive to proactive supply chain management strategies.

Electronic Design to Delivery Index (EDDI)

Spectra's EDDI is a free and comprehensive report that can help you access important industry insights and empower you to navigate the electronics industry supply chain and make better business decisions. It provides a macroeconomic view of the supply and demand trends for 8 major component categories and 15 subcategories, with sourcing data backed by over 20 million parts.

Use Cases for SCR

Smarter Procurement Planning

Use Spectra insights to discover parts with the highest availability risk, as well as risky parts that have recently been restocked. Power your exception handling using Spectra's risk scoring, prioritizing purchases of the riskiest parts and increasing the effectiveness of your procurement teams.

Optimize Safety Stock and Carrying Costs

Discover which high-risk parts on your BOMs require safety stock, while streamlining your inventory of low-risk parts. Make the space on your warehouse shelves count.

Identify Gaps in Alternates

Find out which of your FFF Alternates are effectively mitigating your supply chain risk, and which are sources of hidden availability risk.

Monitor Supply Chain Risk across Your Organization

Discover supply chain risk trends across product categories, monitor changes over the short and long term, and identify the strengths and weaknesses within BOMs of tens of thousands of parts.

How to Use SCR

SCR is designed to process your entire approved part list at once as a batch. There are two ways to use SCR:

  1. Programmatically through the Nexar API
  2. Manually through the Nexar Portal

To use SCR through the Nexar API, follow the instructions in our guide.

To use SCR through the Nexar Portal, you will need a Comma-Separated Values (CSV) file containing all parts that you wish to gather SCR data on. The CSV should include the following columns:

  • Manufacturer part number (MPN) - the part number assigned by the manufacturer. Used with the manufacturer name to uniquely identify a part. For best results, ensure these are full MPNs, and any MPNs containing special characters (especially commas) are surrounded by double quotes.
  • Manufacturer name - the name of the manufacturer of the part. Used with the MPN to uniquely identify a part. The articles here describe how to find a valid manufacturer name.
  • Internal part number (PN) - an ID specific to your parts list that allows parts to be grouped (e.g. as a set of alternates). Parts with the same PN will be considered together in IPN Historical Procurability calculations (see below) but will otherwise be ignored. If you do not want to group parts, this can be a unique ID for the part (e.g. the line number in the file).
  • Estimated Annual Usage (EAU) - the planned or estimated annual usage, in pieces, of your part. It is used to calculate the procurability of a part by comparing it to market availability. Our procurability calculations assume that you will not be able to purchase the entire stock from the market at any given time (as stock is often spread across several suppliers), and it also assumes you will not attempt to buy your entire annual usage in one buy. If you are attempting to purchase a year’s worth of usage in advance, we recommend increasing this to 200-400% of your annual usage. A part will be considered "procurable" if the stock level for the part is greater than or equal to the input EAU value.

The first row of the CSV should consist of column headers. Your CSV may contain additional columns beyond these, but the preceding four columns are the minimum necessary input data.

Use the following steps to augment your report with Spectra data:

  1. Navigate to the Nexar Portal at, log in, and select the SCR tab in the left menu bar.
    • If you don't see the SCR option in your left menu bar, your SCR access may not have been activated yet. Contact your account executive to activate it.
  2. Select the Start New Report button.
  3. Select your CSV file by dragging and dropping it into the browser window, or select the Browse button to select the file. Once you have selected the file, select the Next button in the bottom right corner.
  4. In order to ensure we interpret your data correctly, we need to map your CSV columns to our data model. Use the drop-down menus to select each column name from your CSV that maps to the corresponding required field. When you have completed your selections, select Submit in the bottom right corner.
  5. Your CSV will now be uploaded and processed. Processing generally takes around 10 minutes, and may take longer for large files (more than 100,000 rows). The SCR page may need to be refreshed to show an updated job status.
  6. Once your report has finished processing, you may select the expand symbol at the right end of the row to pop out a small dashboard giving some general supply chain insights on your report.
  7. To download the full report, select the download symbol next to the report.
