Crystals Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of approved substitutes such as the ECS-.327-7-34B-TR if original stock is unavailable. Ensure that replacement components meet identical electrical specifications including frequency, load capacitance, and ESR values to maintain circuit integrity.

Crystals Selection Notes

Select this component for applications requiring a standard 32.768 kHz reference with a 9 pF load capacitance. Consider the 100 kOhm ESR specification when designing oscillator circuits to ensure stable startup. Verify that the SMD footprint matches the 4.90mm x 1.80mm package dimensions required by the target PCB layout.

Crystals Part Context

This part belongs to the family of SMD tuning fork crystals produced by ECS Inc. These components are distinct from active oscillators, functioning as passive resonant elements that require an external oscillator circuit to generate a square wave output signal based on the quartz resonance.

Crystals Replacement Considerations

The ECS-.327-9-39-TR is listed as obsolete. Publicly confirmed substitute part numbers include the ECS-.327-7-34B-TR. Verify that any substitute maintains the same 32.768 kHz frequency and compatible load capacitance.
