CROSS-REFERENCE ALTERNATIVE
COS4047B is a Chinese-manufactured Multivibrator / Oscillator IC from COSINE (科山芯创) that cross-references to CD4047B.
It is a SOP14 device positioned as a domestic-supply option against the imported: shorter lead times, no allocation risk and a stable price for volume production. Because the parts are not pin-identical in every case, the engineering checklist below lists what to verify before you commit.

COS4047B — Multivibrator / Oscillator IC, alternative to CD4047B
COS4047B is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for CD4047B. Imported parts in this class are frequently subject to allocation, long lead times and steep price swings. A Chinese-manufactured equivalent removes that exposure: the parts are production-validated in industrial, consumer and automotive designs and ship from stock on a short lead time.
Cross-reference chart — which imported parts does COS4047B replace?
Every imported part number that COS4047B is published as a cross-reference alternative to, per the COSINE (科山芯创) 2025 selection table:
| imported part number | brand | Replaced by (this part) |
|---|---|---|
| CD4047B | — | COS4047B |
Cross-reference means functional equivalence in the same application role. It is not a blanket claim of pin-for-pin identity — confirm package, pinout and the parameters listed below before you release a design change.

What to verify before substituting COS4047B
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Supply voltage range across the full CD4000-series window (3 V to 18 V class)
- Astable vs monostable mode configuration and the timing R/C pins used
- Timing equation and the external R/C values — the formula must match to keep the same frequency
- Output drive current and whether the needed buffering
- Trigger and retrigger input behaviour and edge requirements
- Package and pinout, including unused-input handling
Typical applications
- Timing and pulse generation
- Frequency division and clock generation
- Oscillator and tone generation
- Sequencing and delay circuits
- Legacy CD4000-series logic replacement
- Test and instrumentation timing
