RK73H1HTTC1003F

RK73H1HTTC1003F is a ROHM (ROHM Semiconductor) chip resistor from the RK73H series. It is a fixed-value surface-mount resistor. The marking “1003” indicates a resistance of 100 kΩ, and “F” denotes a ±1% tolerance. The RK73H family targets high-precision, stable performance with good long-term reliability in compact SMD packages, suitable for precision analog/digital circuits. For exact electrical specs (temperature coefficient, voltage rating, power rating, package size) see the ROHM RK73H1H/H series datasheet.

I don’t have enough data to identify RK73H1HTTC1003F or list equivalents. Please provide the manufacturer or a datasheet (or tell me the component type, key specs — e.g., resistor value/tolerance/configuration, or regulator voltage/current, package). With that I can quickly name direct equivalents (same specs and footprint).

Here are concise features for RK73H1HTTC1003F:
- Series/type: RK73H1H thick-film SMD chip resistor (RK73 family)
- Resistance: 10 kΩ (code 1003)
- Tolerance: ±1% (F)
- Temperature coefficient: H code (typical around 100 ppm/°C)
- Power rating: ~125 mW (typical for RK73 size)
- Termination: Ni barrier with Sn plating
- Compliance: RoHS compliant
- Package: Small RK73 SMD footprint, suitable for high-density PCB layouts
Applications: general precision resistor usage in compact, dense circuits.

I can’t reliably identify the pin count or function from the part number alone. RK73H1HTTC1003F appears to be a specific manufacturer part; I don’t have browsing access to pull its datasheet. Please either:
- Provide the manufacturer or a link to the datasheet, or
- Paste the part’s marking/description or a photo.
With that I’ll give the exact pin count and pin functions.
