Oscillators Procurement Notes

Verify the specific suffix 'T3' against official MMD documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required 3.3V supply and load capacitance parameters. Cross-reference the part number with authorized distributors to confirm RoHS compliance status and availability. Validate that the component meets the intended environmental temperature requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this oscillator when a precise 4 MHz reference is required for digital logic circuits. Consider the ±25 ppm stability tolerance relative to system timing accuracy needs. Evaluate the 14 mA current draw against available power budgets. Confirm the 3.3V supply compatibility with the target circuit's voltage levels and interface requirements.

Oscillators Part Context

This component belongs to the MSH series of surface-mount crystal oscillators from MMD Components. The series offers various frequencies optimized for general-purpose timing applications. The MSH302548AH-4.000MHZ-T3 specifically targets designs requiring a 4 MHz clock signal with standard HCMOS compatibility and moderate stability.

Oscillators Replacement Considerations

Compatible substitutes include other 4 MHz HCMOS oscillators from MMD or third-party manufacturers with identical 3.3V operation and similar footprint dimensions. Verify pinout compatibility and electrical characteristics such as drive level and load capacitance before substitution.
