NE555DR is the industry-standard 555 precision timer from Texas Instruments in an 8-pin SOIC package, for oscillation, delay and pulse-generation circuits. Its advantage is ubiquity: the 555 architecture has been in continuous production for decades, so designs, application notes and engineer familiarity are universal — but that ubiquity is also the procurement risk, because the open market carries remarked and substandard copies. Selection advice: DR denotes SOIC-8 on tape and reel; always quote the full NE555DR code and require lot and date-code traceability rather than accepting loose or unmarked stock. For new designs, confirm whether your circuit needs the bipolar NE555 or the CMOS LMC555 variant — they are not interchangeable in all applications.
Ordering-code highlights reviewed against official manufacturer documentation.
NE555 is available in the following manufacturer order codes. They share the same Precision timer design; the table highlights package, packing and ordering differences. Quote the exact code your BOM needs.
| Order code | Package | Packing | Key difference |
|---|---|---|---|
| NE555DR | SOIC-8 | — | — |
| NE555P | PDIP-8 | TUBE | Package/pins: PDIP (P), 8 pins; NE555DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is TUBE, 50 per pack; NE555DR is LARGE T&R, 2,500 per pack. |
| NE555PWR | TSSOP-8 | LARGE T&R | Package/pins: TSSOP (PW), 8 pins; NE555DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 2,000 per pack; NE555DR is LARGE T&R, 2,500 per pack. |

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — NE555P: Package/pins: PDIP (P), 8 pins; NE555DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is TUBE, 50 per pack; NE555DR is LARGE T&R, 2,500 per pack.; NE555PWR: Package/pins: TSSOP (PW), 8 pins; NE555DR is SOIC (D), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 2,000 per pack; NE555DR is LARGE T&R, 2,500 per pack.. NE555DR itself is the SOIC-8 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.
From the verified technical profile: Function: General-purpose single timer; Operating modes: Astable and monostable; Operating supply: 4.5 V to 16 V. These are the catalog-recorded values for NE555DR — always re-check them against the manufacturer datasheet revision quoted on your BOM before finalizing the design.
