Warranty

We warrant that every part we ship conforms to the datasheet in force at the date of the order acknowledgement and is free from defects in materials and workmanship for twelve months from the date of shipment, unless a different period is stated in the order acknowledgement.

1. What we will do

If a part fails to conform during the warranty period, we will – at our option – repair it, replace it, or credit its purchase price. Where a replacement is not available because the part has been discontinued, we will offer the nearest equivalent or a full credit. We pay reasonable return freight for confirmed warranty failures; you pay freight on parts that prove to be within specification.

2. Conditions

The warranty applies provided that:

• The part has been stored, handled and assembled in accordance with its datasheet, including the moisture sensitivity level and ESD precautions.
• Operating conditions – supply voltage, drive level, load capacitance, ambient temperature and airflow – are within the published limits.
• The part has not been modified, reprocessed, remarked or repaired by anyone other than us.
• The PCB design respects the layout guidance in the datasheet, including thermal relief and keep-out around the crystal.
• The part has not suffered mechanical damage, including bent leads, cracked ceramic base or damage from ultrasonic cleaning.

3. What is not covered

• Normal wear, ageing beyond the specified drift, and parametric drift within the datasheet limits over life.
• Damage caused by ESD, overvoltage, reverse polarity, soldering outside the recommended profile, or cleaning agents.
• Failure of an assembly where the part itself meets specification and the fault lies elsewhere.
• Parts supplied by third parties against your explicit instruction, where we have identified them as non-standard.
• Consumables, samples supplied free of charge, and evaluation boards.

4. Making a claim

1. Contact sales@xtalstore.com with the order number, part number, lot code, quantity affected and a description of the failure.
2. We issue an RMA number and, where the failure is application-related, ask for a schematic extract or a description of the operating conditions.
3. Return a minimum of five failed parts, together with the lot code from the reel label.
4. We run failure analysis – typically frequency, resistance, drive level, insulation and a temperature sweep – and report back within ten working days of receipt.
5. Where the failure is confirmed as ours, we ship a replacement against the next available stock or issue a credit note.

5. Failure analysis reports

A written failure analysis report is available on request for any confirmed warranty failure. The report covers the test conditions, the observed deviation, the root cause where it can be determined, and any corrective action taken. Reports are shared with the account contact and are treated as confidential.

6. Traceability

Every shipment carries a lot code that links the parts to the raw material batch, the production line, the operator shift and the test record. We retain these records for ten years, which means a failure reported years after shipment can still be traced to its production conditions.

7. Statutory rights

This warranty is given in addition to, and does not replace, any statutory rights you have under the law of your jurisdiction, including consumer rights and any implied terms that cannot be excluded. Where local law grants a longer minimum period, that period applies.

8. Extended warranty

For automotive, medical and space programmes we can offer an extended warranty or a bespoke reliability programme – for example 1,000-hour burn-in, 500-cycle temperature shock, or lot-specific qualification to AEC-Q200. These are quoted per project; contact your account manager.
