Pro-active Monitoring of Component life-cycles Regular component monitoring allows a user to anticipate problems before they occur. There are some excellent tools such as I.H.S Parts Intelligence® and BOM (Bill Of Materials) Intelligence® which track a component’s life-cycle, lead-time, and specification changes over time.
Ensure you are aware of Product Discontinuation Notices (PDN’s) which affect you
There are many Component Management Databases which can provide you with a PDN notification service. This can be generic: where you are shown everything, or specific: where you load BOM structures into the database and it then matches and highlights any PDN which affects your products.
Last-Time-Buy – What to forecast? LTB orders are inevitable, but a supplier with an established End- of-Life transition partner offers at least the hope of risk-free ongoing authorized stock and production if demand rises, re-designs are delayed, or in-service commitments extended.
Purchase from AUTHORISED Sources
There is a common misconception that once the original manufacturer stops making a component, unauthorized/grey market sources are the only option. Nothing could be further from the truth. The zero-risk option of an AUTHORISED after-market supplier like Rochester Electronics, should always be the number one choice.
The risk of counterfeit and simple poor-quality product from unauthorised sources represents a significant risk to production yield and failure rates (MTBR) in the field. Inferior or substandard “Testing” by unauthorized 3rd parties gives a veneer of confidence that “goodness” can be tested. In truth,

the testing is a poor partial copy of the original manufacturers test processes. Unauthorised component risks include: • Poor handling – resulting in mechanical or ESD damage.
• Poor storage – excessive heat, cold, or moisture during any part of its storage life. leading to: failed solderability or “pop-corning”
• Fake documentation. • Recovered, re-marked, or re- packaged components claiming to be something else. Original Components
manufacturers DO NOT provide guarantees for products purchased through unauthorised channels.
Sources like Rochester Electronics receive their stock exclusively from the manufacturers. Components never leave the authorized bubble and as a result Rochester are able to offer the original warranties and guarantees. Increasingly Rochester are also able to offer ongoing build from known-good-die and test product according to the original test procedures. Rochester produced parts are current date code with no solderability risk and are marked with the original manufacturer’s P/ No. 100% compliant with the original specification.
