How to source an obsolete electronic component without buying a counterfeit
J.P. Electronics · Updated 28 August 2026
To source an obsolete electronic component safely, work through five steps in order: read the manufacturer’s own end-of-life notice, check remaining authorised stock, identify the manufacturer’s declared successor, evaluate a functional equivalent from another manufacturer, and only then consider the open market. Each step is lower risk than the one after it, and most obsolescence problems are solved before step five.
Step 1. Read the manufacturer’s notice, not a third-party listing
Every real obsolescence starts with a product discontinuation notice from the manufacturer. It gives the last order date, the last ship date, and usually a recommended replacement. Third-party feeds are often months out of date. J.P. Electronics checks the manufacturer’s own product page or notice, never a feed.
Step 2. Check what authorised stock is left
Between the last order date and the last ship date there is usually a window to place a final order. If your annual usage is known, this is the cheapest solution available and carries no qualification cost.
Step 3. Take the manufacturer’s successor seriously
Manufacturers usually name a replacement, and it is usually pin compatible. Where it is not, the difference is documented. This is the lowest-risk change you can make.
Step 4. Evaluate a functional equivalent from another manufacturer
When there is no successor, an equivalent from another line will usually do the job. Test before committing. Our line card spans both established and second-source manufacturers, which is exactly what this step needs.
Step 5. The open market, last and carefully
If you must buy on the open market, buy from someone who provides traceability documentation, and budget for incoming inspection. Our anti-counterfeit policy explains what documentation to expect from any legitimate source.
What to do before the next one happens
Tell your distributor which part numbers you depend on. Email sales@jpegroup.com with your critical parts list and we will pass on the manufacturer notices that affect it.
