The parts are out there if you know where to look.

Obsolescence Management
An active member of COG (Components Obsolescence Group), Charcroft can recommend alternatives to passives which are already obsolete and undertake Parts List Audits to reduce the risk of future obsolescence in new designs.

Sourcing Alternatives
Charcroft can source alternatives to passives from a part number, product description, NATO stock number or release specification. Typically, most obsolete passives can be replaced by a number of direct equivalents manufactured under different part numbers or mil-spec/BS/CECC numbers.



Company acquisitions can also mean that apparently obsolete passives are available under a new manufacturer name. Click on a company name below, or type a manufacturer name in the ‘Who Are They Now’ search engine, to find a list of changing company names.

Parts List Audits

Regular audits of parts lists can identify obsolete and obsolescent passives, providing time to plan a mitigation strategy. A typical audit can identify up to 5% of passives which are obsolete, or at risk of obsolescence.
