Product details
Overview
603-25-173JA4I8 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 603-25-173JA4I8 datasheet, 603-25-173JA4I8 pinout, 603-25-173JA4I8 application, or 603-25-173JA4I8 equivalent, key selection criteria include operating temperature range, load capacitance matching, aging specification (±5 PPM/10 years), soldering profile compliance (260°C/10 s), and RoHS-compliant gold termination.
Technical Context
This is a passive, two-terminal fundamental-mode AT-cut quartz crystal resonator - not an oscillator IC - requiring external sustaining circuitry (e.g., Pierce gate) to oscillate. It operates at 25.000 MHz with fixed 12 pF load capacitance and exhibits low drive-level sensitivity (≤0.1 mW) and tight thermal stability (±20 PPM over –40°C to +85°C).
The JA4 package is a ceramic leadless chip carrier (CLCC) with Au-plated terminations, MSL1 rating, and defined mechanical outline per IDT/RENESAS spec. Its 16.75 mg mass and 3.2 × 2.5 mm footprint support compact, high-density PCB layouts in space-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency | 25.000 MHz - exact fundamental resonance frequency; must match oscillator circuit's target frequency. |
| Frequency Tolerance @ 25°C | ±20 PPM Max - initial calibration accuracy at room temperature; impacts system timing margin before thermal drift. |
| Operating Temperature Range | –40°C to +85°C - validated performance envelope for industrial-grade operation without derating. |
| Load Capacitance (CL) | 12 pF - required external capacitive load for nominal frequency; mismatch causes measurable frequency shift. |
| Equivalent Series Resistance (ESR) | 50 Ω Max - limits minimum gain requirement of oscillator circuit; lower ESR eases start-up reliability. |
| Aging (10 years) | ±5 PPM Max - long-term frequency drift due to material stress relaxation; critical for uncalibrated systems. |
| Drive Level | 0.1 mW Max - maximum power dissipation to avoid crystal degradation or mode hopping. |
Pinout & Package
Package: 3.2 × 2.5 × 1.0 mm JA4 ceramic leadless chip carrier (CLCC), surface-mount, 2-pad configuration with Au-plated terminations, MSL1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pad 1 | Crystal Terminal A | One electrode of the quartz blank; connects to oscillator inverter input or output depending on topology. |
| Pad 2 | Crystal Terminal B | Opposite electrode; completes resonant loop with Pad 1; symmetric layout enables bidirectional placement. |
Key Features
| Feature | Design Value |
|---|---|
| Fundamental-mode resonance | Enables direct 25 MHz operation without overtone filtering complexity or spurious mode risk. |
| ±20 PPM frequency stability over –40°C to +85°C | Ensures timing consistency across full industrial temperature range without active compensation. |
| 12 pF load capacitance | Matches standard Pierce oscillator designs using common 22–27 pF external capacitors (with PCB stray C). |
| RoHS-compliant, Pb-free, Au termination | Supports lead-free reflow assembly and ensures corrosion resistance and solder-wettable reliability. |
| MSL1 rating | Permits unlimited floor life and eliminates bake-out requirements prior to SMT assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quartz crystal resonator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM3B-25.000MHZ-D2Y-T | Same 25 MHz, 12 pF CL, –40°C to +85°C, but ±10 PPM tolerance and 60 Ω ESR. | Tighter initial tolerance suits higher-accuracy UART or USB timing; higher ESR may require oscillator gain margin check. | Select when ±10 PPM initial accuracy is mandatory and board-level oscillator gain exceeds 5× ESR. |
| FA-238V-25.000M | 25 MHz, 12 pF CL, –40°C to +85°C, ±20 PPM, but 80 Ω ESR and 3.2 × 2.5 × 0.7 mm height. | Thinner profile fits ultra-low-profile modules; higher ESR demands verified oscillator loop gain. | Choose for height-constrained designs where 0.3 mm thickness reduction outweighs ESR trade-off. |
Compared with ABM3B-25.000MHZ-D2Y-T and FA-238V-25.000M, the 603-25-173JA4I8 offers balanced ESR (50 Ω), industry-standard height (1.0 mm), and guaranteed aging (±5 PPM/10 yr), making it optimal for long-lifecycle industrial control and medical devices where reliability trumps marginal tolerance improvement.

FAQ
What is the load capacitance requirement for the 603-25-173JA4I8?
The 603-25-173JA4I8 requires a 12 pF load capacitance to operate at its nominal 25.000 MHz frequency. This value must be realized by the sum of external capacitors, PCB trace capacitance, and input capacitance of the oscillator circuit. Deviations will cause measurable frequency offset - typically ±0.02% per 1 pF mismatch - so precise capacitor selection and layout are essential for the 603-25-173JA4I8.
Is the 603-25-173JA4I8 compatible with lead-free reflow processes?
Yes, the 603-25-173JA4I8 is fully compatible with lead-free reflow. It is rated for peak soldering temperatures up to 260°C for 10 seconds and features Au-plated terminations. Its MSL1 classification means no dry-pack or baking is required before assembly, simplifying manufacturing flow for the 603-25-173JA4I8 in high-volume SMT lines.
Does the 603-25-173JA4I8 require external capacitors to oscillate?
Yes, the 603-25-173JA4I8 is a passive crystal resonator and requires external load capacitors - typically two matched capacitors (e.g., 22 pF each) - to form a Pierce oscillator with an inverting gate or dedicated oscillator IC. The total effective load capacitance seen by the 603-25-173JA4I8 must equal 12 pF, including PCB parasitics and IC input capacitance.
What is the aging specification for the 603-25-173JA4I8 over time?
The 603-25-173JA4I8 has a maximum aging specification of ±5 PPM over 10 years under normal operating conditions. This long-term drift is caused by internal stress relaxation in the quartz blank and is measured after initial stabilization. It is a key differentiator for applications like medical devices or industrial controllers where calibration-free operation over product lifetime is required for the 603-25-173JA4I8.
Can the 603-25-173JA4I8 be used in automotive applications?
The 603-25-173JA4I8 is qualified for –40°C to +85°C operation and meets industrial reliability standards, but it is not AEC-Q200 qualified. For automotive cabin or ADAS modules operating within this temperature range and where qualification is not mandated by OEM, the 603-25-173JA4I8 is frequently deployed - however, full AEC-Q200 certification requires additional testing beyond the 603-25-173JA4I8 datasheet scope.
