Crystals Procurement Notes

Verify the specific suffix 'BA38' against official Suntsu datasheets to confirm temperature range and stability specifications, as suffix variations often denote critical environmental or electrical differences. Ensure compatibility with 19 pF load capacitance requirements in the target circuit design. Cross-reference RoHS compliance status if restricted substances are a concern for your manufacturing process. Confirm package dimensions match your PCB footprint exactly before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency is required with ±30 ppm stability over an extended industrial temperature range. The 19 pF load capacitance must match the oscillator circuit's external capacitor values to ensure accurate frequency output. Consider the 4-SMD no-lead package for space-constrained designs requiring reflow soldering compatibility. Evaluate ESR limits against driver circuit capabilities to guarantee reliable startup and sustained oscillation.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics, Inc., which offers various frequency and package options. The SXT21419BA38 variant specifically targets applications needing wider temperature tolerance compared to commercial grade parts. Similar models in the series may differ in load capacitance, frequency, or operating temperature ranges, necessitating careful comparison of datasheet parameters when substituting or designing around this component family.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 19 pF load capacitance, 4-SMD package, and -30°C to +85°C temperature range. Verify that alternative components maintain identical ±30 ppm stability and 100 Ohm ESR specifications. Check pinout compatibility despite the leadless design, as internal electrode configurations may vary between manufacturers.
