NJM78L variants from Nisshinbo Micro Devices Inc.
NJM78L Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
NJM78L is a Nisshinbo Micro Devices Inc. order-code family — not a single orderable MPN. This page lists 4 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: TO-243AA | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 85°C | Output Type: Fixed | Voltage Input Max: 30V | Supplier Device Package: SOT-89 Other listed variants describe: Package: TO-243AA | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 85°C | Output Type: Fixed | Voltage Input Max: 35V | Supplier Device Package: SOT-89-3; Package: TO-243AA | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 85°C | Output Type: Fixed | Voltage Input Max: 40V | Supplier Device Package: SOT-89.
Across listed variants, watch these parameters: packages: TO-243AA.
Suffix examples in this family: 08UA-TE1, 09UA-TE1, 12UA-TE1, 18UA-TE1. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: NJM78L08UA-TE1, NJM78L09UA-TE1, NJM78L12UA-TE1, NJM78L18UA-TE1.
Key Features
- Footprint / package: TO-243AASingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 4 distinct suffix patternsExamples: 08UA-TE1, 09UA-TE1, 12UA-TE1, 18UA-TE1. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Integrated Circuits (ICs) — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on NJM78L map to package, grade, and reel options.
NJM78L uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 08UA-TE1, 09UA-TE1, 12UA-TE1, 18UA-TE1.
Full MPN examples: NJM78L08UA-TE1, NJM78L09UA-TE1, NJM78L12UA-TE1, NJM78L18UA-TE1.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right NJM78L Integrated Circuits (ICs)
Match the footprint first
Packages here: TO-243AA. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For NJM78L, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "NJM78L" — include the full suffix (e.g. 08UA-TE1, 09UA-TE1, 12UA-TE1). RFQ with reel/tube preference and required date code.
