MC3672

MC3672 is an obsolete 3-axis digital accelerometer from MEMSIC in a 1.29 × 1.09 × 0.74 mm CSP-8 package — EOL since the 2023-07-03 notice, with MEMSIC recommending MC3630/MC3632/MC3635 as replacements. The tiny CSP footprint was the selection point for space-constrained motion sensing before discontinuation. Selection advice: for new designs, qualify one of the MEMSIC-recommended replacements (MC3630/MC3632/MC3635) and verify range and interface against the datasheet; for repairs and last-time builds, send quantity and date-code requirements with your RFQ and we will check what can still be sourced with traceability. Parameters verified against the MEMSIC datasheet.

Sourcing note

Confirm measurement range, accuracy, package orientation, calibration and environmental requirements.

Before you request a quote

Do not design in — part is obsolete
MEMSIC issued the end-of-life notice for MC3672 on 2023-07-03 and distributors list it as Obsolete. For new designs use the manufacturer-recommended replacements MC3630, MC3632 or MC3635, and confirm footprint, supply and register-map compatibility against the replacement datasheet before committing.
Verify traceability on any offered parts
Any MC3672 offered today comes from leftover channel supply rather than factory production. Request date code, lot code and original packing, and confirm the parts match the CSP-8 ordering information in the MC3672 datasheet before purchase.

COMMON QUESTIONS

MC3672 FAQ

Is MC3672 still in production?

The manufacturer lists MC3672 as Obsolete. Manufacturer-channel supply is therefore lot-dependent and must be confirmed per RFQ — tell us your quantity and date-code requirements and we will check what can still be sourced. If you are designing this part in, ask us about an approved replacement before committing the BOM.

What are the key specifications of MC3672?

From the verified technical profile: Lifecycle status: Obsolete — EOL notice 2023-07-03; Manufacturer-recommended replacements: MC3630 / MC3632 / MC3635; Axes: X, Y, Z (3-axis). These are the catalog-recorded values for MC3672 — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
