Does your product have a shelf-life or expiration date?

Harwin operates an internal Shelf Life policy for all connector products containing gold, tin and silver plated components. This policy states a shelf life of:

  • Tin and Silver plated components = 48 months.
  • Gold plated components = 60 months.

During this period the connectors are:

  • Stored in accordance with IEC 60721-3-1:2018 (Classification of groups of environmental parameters and their severities – Storage) Class 1K21 for the following categories:
    • Low Air Temperature: +5°C to High Air Temperature: +40°C
    • Low Relative Humidity: 5% to High Relative Humidity: 85%
  • Kept in the original sealed Harwin packaging at all times, complete with batch traceability numbers.

For connector products stored at Harwin, at the end of their respective shelf life duration, any components that have not been sold are destroyed and responsibly recycled.

Product held by our customers will continue to remain unaffected beyond the above dates for a further 24 months, for all of the respective plating finishes, but only if stored under the same conditions. Harwin therefore recommends that any components stored beyond these periods are tested for solderability prior to production processing.

This Policy is also available in PDF Format for download.
