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.

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.

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. Contact Charcroft’s obsolescence team on obsolescence@charcroft.com for more information on parts list auditing or for alternatives to obsolete passives.

Company acquisitions can also mean that apparently obsolete passives are available under a new manufacturer name. The 'who are they now' page shows how companies have changed.
