Littelfuse 59135
59135 variants from Littelfuse
59135 Overview
What changes between part numbers, and what to check before you lock the BOM — Magnetic Sensors.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 1-S-02-A, 1-T-02-F. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Magnetic 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 2 59135 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 |
|---|---|---|---|---|---|---|
| 59135-1-S-02-A | Proximity Sensor Reed NO 1.85cm 200VDC 140VAC 2-Pin | Littelfuse | Active | Compliant | In Stock | |
| 59135-1-T-02-F | Proximity Sensor Reed NO 1.71cm 200VDC 140VAC 2-Pin | Littelfuse | Active | Compliant | In Stock |

How to Choose the Right 59135 Magnetic 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 59135, 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 "59135" — include the full suffix (e.g. 1-S-02-A, 1-T-02-F). RFQ with reel/tube preference and required date code.
