Product details

27 MHz MEMS XO with AEC-Q100 Grade 1 temperature range

The DSC1001AL5-027.0000: The MEMS resonator provides better shock and vibration tolerance than quartz, which matters for chassis-mounted ECUs and transmission controllers.

Standby power-down and wide supply range

A standby (power-down) function drops the supply current to 15 µA max when the enable pin is pulled low — useful for battery-backed modules that must preserve the clock reference only during active operation. The supply voltage range spans 1.8V to 3.3V, so the same oscillator can serve as a common reference for 1.8V and 3.3V logic domains without a level translator. Active current draw is 7.2 mA max at full speed — low enough that thermal rise in the no-lead package is negligible even in a confined ECU enclosure.

Sourced through independent distribution, this part is quoted to order against the BOM quantity.

Frequently asked questions

Where can I buy DSC1001AL5-027.0000 and how is it quoted?

The DSC1001AL5-027.0000 is an active-production part from Microchip Technology. No stock-holding claim is made; each order is sourced per request.

Is DSC1001AL5-027.0000 suitable for automotive applications?

Yes — it carries an AEC-Q100 rating and operates from -40°C to +105°C, which covers under-hood and engine-bay ambient temperatures. The MEMS resonator also provides better shock and vibration tolerance than quartz, making it suitable for chassis-mounted ECUs.

Does DSC1001AL5-027.0000 have a standby power-down feature?

Yes — the standby (power-down) function reduces supply current to 15 µA max when the enable pin is pulled low. This is useful for battery-backed modules that only need the clock reference during active operation.

Can DSC1001AL5-027.0000 replace a standard 27 MHz quartz oscillator?

It is a direct functional replacement for a 27 MHz quartz oscillator in terms of frequency and CMOS output, but the MEMS resonator and AEC-Q100 qualification make it a higher-reliability choice for automotive and industrial environments. The 4-SMD no-lead package is pin-compatible with many standard 7.0×5.0 mm XO footprints — confirm the pad layout against your existing quartz oscillator before committing.
