Product details
Overview
603-25-173JA4I from Renesas Electronics (formerly IDT) is a 25.000 MHz fundamental-mode quartz crystal resonator in a 3.2 × 2.5 × 1.0 mm JA4 CLCC package, rated for ±20 PPM frequency tolerance and stability over –40°C to +85°C, with 12 pF load capacitance and ≤50 Ω ESR - used as a precision timing reference in industrial microcontrollers and communication PHYs.
For engineers reviewing the 603-25-173JA4I datasheet, 603-25-173JA4I pinout, 603-25-173JA4I application, or 603-25-173JA4I equivalent, key selection criteria include operating temperature range, load capacitance matching, aging specification (±5 PPM over 10 years), soldering profile compliance (260°C/10 s), and RoHS-compliant gold termination.
Technical Context
This is a passive, two-terminal AT-cut fundamental-mode quartz crystal designed for parallel-resonant operation with external load capacitors. It requires no internal circuitry or power supply and functions solely as a mechanical resonance element stabilized by precise crystal cut and electrode metallization.
Its JA4 package is a ceramic leadless chip carrier (CLCC) with Au-plated terminations, MSL-1 rating, and defined mechanical dimensions (3.2 × 2.5 × 1.0 mm). The device operates exclusively in fundamental mode - no overtone capability - and specifies drive level ≤0.1 mW to prevent activity dips or accelerated aging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency | 25.000 MHz - exact nominal oscillation frequency at 25°C with 12 pF load |
| Frequency Tolerance | ±20 PPM max at 25°C - defines initial calibration accuracy before aging or thermal drift |
| Frequency Stability | ±20 PPM max over –40°C to +85°C - constrains total thermal variation in end-equipment operation |
| Load Capacitance (CL) | 12 pF - required external capacitor value per terminal for specified frequency accuracy |
| ESR | ≤50 Ω - limits negative resistance margin needed from oscillator circuit for reliable startup |
| Aging (10 yr) | ±5 PPM max - sets long-term frequency drift budget for maintenance-free deployments |
| Operating Temp | –40°C to +85°C - validated performance range for industrial-grade embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal resonator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM3B-25.000MHZ-D2Y-T | Same 25 MHz, 12 pF CL, ±20 PPM tol/stab, but 3.2 × 2.5 × 0.75 mm height and 100 Ω max ESR | Higher ESR reduces oscillator margin; thinner profile may affect board-level mechanical stress coupling | Select if footprint compatibility exists and oscillator negative resistance ≥150 Ω |
| FA-238 25.0000MAA | 25 MHz, 12 pF CL, ±10 PPM tol (tighter), but only ±15 PPM stability over –20°C to +70°C and 80 Ω max ESR | Narrower temp range and higher ESR limit use in extended-temperature industrial or automotive contexts | Prefer where tighter initial tolerance is prioritized over full –40°C to +85°C stability |
Compared with ABM3B-25.000MHZ-D2Y-T and FA-238 25.0000MAA, the 603-25-173JA4I provides superior thermal stability across the full industrial range and lower ESR for margin-critical oscillator designs - making it optimal for high-reliability, wide-temperature applications despite slightly larger height.

FAQ
What is the load capacitance requirement for the 603-25-173JA4I?
The 603-25-173JA4I requires a 12 pF load capacitance for nominal 25.000 MHz operation. This value must be implemented externally using two matched capacitors (typically 22–24 pF each to ground) in series with the crystal terminals, accounting for PCB stray capacitance. Deviations from 12 pF will shift the actual oscillation frequency proportionally.
Does the 603-25-173JA4I support overtone modes?
No, the 603-25-173JA4I operates exclusively in fundamental mode, as confirmed by its datasheet specification of "Fundamental" resonance mode. It is not designed or characterized for third- or fifth-overtone operation, and attempting to force overtone excitation may result in unreliable startup or increased jitter.
What is the maximum recommended drive level for the 603-25-173JA4I?
The 603-25-173JA4I has a maximum drive level of 0.1 mW. Exceeding this level risks accelerating aging, inducing activity dips, or causing permanent frequency shift. Oscillator circuit design must ensure power dissipation in the crystal remains below this threshold - typically verified via current measurement at the crystal terminals.
Is the 603-25-173JA4I compatible with lead-free reflow processes?
Yes, the 603-25-173JA4I is qualified for lead-free reflow with a maximum soldering temperature of 260°C for 10 seconds, and carries Moisture Sensitivity Level (MSL) 1 - meaning it can be stored indefinitely at ambient conditions without baking prior to assembly.
How does the aging specification of the 603-25-173JA4I impact long-term system accuracy?
The 603-25-173JA4I specifies ±5 PPM maximum aging over 10 years, directly limiting cumulative frequency drift in deployed systems. For example, in a 25 MHz clock, this equates to <±125 Hz drift after a decade - critical for time-sensitive applications like utility metering or telecom synchronization where recalibration is impractical.
