Equivalent or alternative models (verify pinout and specs before use):

- Texas Instruments REF1004-1.2 (1.2 V micropower reference)

- Texas Instruments LM4040A-1.2 and LM4041-1.2 (fixed shunt references near 1.225 V, various tolerances)

- Texas Instruments TLV431/LMV431 (adjustable shunt references; not fixed 1.235 V, check suitability)

- Analog Devices ADR5041 (1.2 V shunt reference, low power)

- ON Semiconductor/Diodes Inc. LM4040/LM4041 series (1.2–5.0 V variants; check the 1.2 V option)

- Legacy LM385-1.2 (various vendors; lower performance, verify requirements)

If none of these meet your exact needs or if you require a drop-in match, please contact our sales team via the Y-IC website for guidance.
