TE Connectivity HPP845E
HPP845E variants from TE Connectivity
HPP845E Overview
What changes between part numbers, and what to check before you lock the BOM — Sensors.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 5 distinct suffix patternsExamples: 031R4, 031R5, 034R5, 131R4, 131R5. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Sensors — 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 Variants
Compare 5 HPP845E part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |

How to Choose the Right HPP845E Sensors
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For HPP845E, 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 "HPP845E" — include the full suffix (e.g. 031R4, 031R5, 034R5). RFQ with reel/tube preference and required date code.
