Product details

Active draw is 5 mA typical at 100 MHz.

Because the DSC1030BI1 uses a 4-SMD no-lead package (5.00 mm x 3.20 mm footprint, 0.90 mm seated height), any pin-compatible replacement must match the same 4-pad land pattern and 3V supply. No direct Microchip cross-reference is published; a functional equivalent from another MEMS oscillator vendor (e.g., SiTime, Abracon) would require verifying the standby logic polarity and output drive strength.

Package and mounting checklist

Surface-mount on a 4-SMD no-lead footprint — the 5.00 mm x 3.20 mm body has no exposed leads; the four pads are on the bottom.

Frequently asked questions

Is the DSC1030BI1-100.0000 obsolete?

Yes. Microchip lists the product status as Obsolete. There is no direct pin-compatible successor from Microchip for this exact order code. The part can be sourced through independent surplus channels; quantities are lot-specific and confirmed at RFQ.

What is the frequency stability of the DSC1030BI1-100.0000?

At 100 MHz, that translates to a maximum frequency deviation of ±5 kHz from the nominal output.

What is the difference between DSC1030BI1 and DSC1030BI2?

The evidence does not specify the BI2 variant. The BI1 suffix in the DSC1030 family typically encodes the output drive strength or standby polarity; confirm the BI2 datasheet for differences in output current or logic levels before substituting.
