CROSS-REFERENCE ALTERNATIVE
COSTLVH431M is a Chinese-manufactured Voltage Reference from COSINE (科山芯创) that cross-references to TLVH431 (TI).
It is a SOT23-3 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.

COSTLVH431M — Voltage Reference, alternative to TLVH431
COSTLVH431M is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for TLVH431 (TI). 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 COSTLVH431M replace?
Every imported part number that COSTLVH431M 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) |
|---|---|---|
| TLVH431 | TI | COSTLVH431M |
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 COSTLVH431M
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Output voltage option: adjustable shunt reference or fixed output, and the reference voltage the design is built around
- Initial accuracy and temperature coefficient over the operating range
- Cathode (operating) current range, including the minimum current needed to regulate
- Dynamic output impedance and its effect on load regulation
- Suffix differences within the same family: the A/M/L suffixes denote different accuracy and voltage grades
- Package and pinout — SOT-23-3 pin assignments must match
- Turn-on and settling behaviour
Typical applications
- ADC and DAC reference inputs
- Power-supply feedback and regulation
- Comparator threshold generation
- Precision measurement and metering
- Shunt-regulator substitution in legacy designs
- Battery monitoring and protection
