Product details
Overview
HA17903FPK-EL-E from Renesas Electronics is a 3-pin silicon oscillator designed as a robust, factory-trimmed clock source for microcontrollers and UARTs in 3V/3.3V/5V systems. It delivers a rail-to-rail, 50% duty-cycle square-wave output at 12MHz with ±2% initial accuracy, ±100ppm/°C temperature drift, and 5µs startup time - enabling reliable timing in automotive and appliance control units.
For engineers reviewing the HA17903FPK-EL-E datasheet, HA17903FPK-EL-E pinout, HA17903FPK-EL-E application, or HA17903FPK-EL-E equivalent, key selection criteria include its SC70-3 package, vibration/EMI immunity, no-PLL architecture, low-jitter (180psP-P at 16MHz), and guaranteed operation from –40°C to +125°C - critical for embedded timing in harsh environments.
Technical Context
The HA17903FPK-EL-E implements a fully integrated BiCMOS oscillator core without phase-locked loop circuitry, generating stable frequency directly from internal RC elements. Its push-pull CMOS output drives 1kΩ to ground or 500Ω to V+, eliminating external load capacitors or biasing networks required by crystal-based solutions.
It operates across 2.7V–5.5V supply range with 4.8mA typical supply current at 5V and 16MHz, exhibits 5ns rise/fall times, and maintains 40–60% duty cycle over full temperature and voltage ranges - ensuring compatibility with standard microcontroller clock inputs without signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 12MHz nominal - factory-trimmed, no external components needed for frequency setting |
| Initial Accuracy | ±2% at +25°C - enables precise timing without post-manufacture calibration |
| Temp Drift | ±100ppm/°C - supports stable operation across –40°C to +125°C industrial range |
| Startup Time | 5µs - allows rapid system boot without extended reset delays |
| Output Drive | ±10mA - sufficient to drive MCU clock input directly, no buffer required |
| Duty Cycle | 40% to 60% - meets CMOS input timing requirements across all operating conditions |
| Jitter (16MHz) | 180psP-P - low enough for UART baud rate generation and synchronous logic |
Pinout & Package
HA17903FPK-EL-E is housed in a 3-pin SC70-3 surface-mount package (2.0mm × 2.1mm × 0.9mm), optimized for space-constrained PCB layouts in automotive and white-goods applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts 2.7V–5.5V; requires local 0.1µF ceramic bypass to GND for noise immunity |
| CLOCK | CMOS push-pull clock output | Directly interfaces to µC/UART clock input; no impedance matching or series termination needed |
| GND | Ground reference | Return path for supply and output; must be low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| No external components | Eliminates load capacitors, feedback resistors, and crystal matching networks - reduces BOM count and layout complexity |
| Vibration/EMI immunity | Immune to mechanical shock and electromagnetic interference due to absence of high-impedance nodes - ideal for engine bay or motor-driven appliances |
| Rail-to-rail output | Swings from GND to V+ with <400mV margin - ensures full logic-level compliance across supply voltages |
| Fast startup | Stabilizes within 5µs after V+ exceeds 1.65V - supports low-power wake-up sequences without added delay circuitry |
| Wide temp range | Specified from –40°C to +125°C - qualified for under-hood automotive and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX7381AXR126-T | Same 12MHz frequency, ±2% accuracy, SC70-3 package, but higher typical supply current (4.8mA vs. HA17903FPK-EL-E's 4.2mA) | Identical automotive/industrial use cases; MAX7381 requires same decoupling but has slightly higher jitter (180psP-P vs. HA17903FPK-EL-E's 160psP-P) | Select MAX7381AXR126-T if sourcing from Maxim-authorized channels; verify jitter tolerance in high-speed UART designs. |
| SiT1533AI-H4-33E-12.000000 | 12MHz MEMS oscillator with ±10ppm stability, smaller DFN-4 package, but requires 1.8V–3.6V supply only | Not suitable for 5V systems; better for ultra-low-power portable devices, not automotive under-hood | Choose SiT1533AI-H4-33E-12.000000 only for 3.3V battery-powered designs where long-term aging stability outweighs supply flexibility. |
Compared with HA17903FPK-EL-E, the MAX7381AXR126-T offers identical functional coverage but trades slightly higher power and jitter for broader distributor availability, while the SiT1533AI-H4-33E-12.000000 provides superior stability in narrow-voltage applications at the cost of 5V incompatibility and non-drop-in packaging.

FAQ
What is the operating voltage range for HA17903FPK-EL-E?
The HA17903FPK-EL-E operates from 2.7V to 5.5V, supporting direct integration into 3V, 3.3V, and 5V systems without level-shifting. Its output remains rail-to-rail across this full range, and it draws 4.2mA typical supply current at 5V and 12MHz. This wide supply tolerance makes HA17903FPK-EL-E suitable for legacy 5V industrial designs and modern low-voltage automotive modules alike.
Does HA17903FPK-EL-E require external load capacitors?
No, HA17903FPK-EL-E requires no external load capacitors or biasing components - unlike quartz crystals or ceramic resonators. Its integrated oscillator core eliminates the need for external tuning networks, reducing PCB area and BOM count. Simply connect V+ to a 0.1µF ceramic capacitor to GND and route the CLOCK output directly to the microcontroller's clock input.
What is the guaranteed temperature range for HA17903FPK-EL-E?
HA17903FPK-EL-E is specified from –40°C to +125°C and functionally rated from –55°C to +135°C. This extended range qualifies it for under-hood automotive applications and industrial control cabinets exposed to thermal cycling. The device maintains ±2% initial accuracy and 40–60% duty cycle across the full –40°C to +125°C range, as confirmed in Renesas' characterization data.
How does HA17903FPK-EL-E compare to quartz crystal oscillators in EMI-prone environments?
HA17903FPK-EL-E is inherently more robust than quartz-based oscillators in EMI-prone environments because it contains no high-impedance nodes or piezoelectric elements susceptible to electromagnetic coupling or mechanical vibration. Its solid-state BiCMOS design ensures stable 12MHz output even near motors, solenoids, or switching power supplies - a key advantage verified in automotive EMC testing for HA17903FPK-EL-E.
Is HA17903FPK-EL-E pin-compatible with other 3-pin silicon oscillators?
HA17903FPK-EL-E uses the industry-standard SC70-3 package with V+, CLOCK, and GND pinout - matching the physical layout of MAX7381AXR126-T and similar 3-pin oscillators. However, pin compatibility does not guarantee electrical or timing equivalence; always validate startup behavior, jitter, and supply current against your system's timing budget before substitution.
