Product details
Overview
603-24-127JA4I from Integrated Device Technology, Inc. is a 24.000 MHz fundamental-mode quartz crystal resonator in a 3.2 × 2.5 × 1.0 mm JA4 CLCC package, with ±30 ppm frequency tolerance and stability over −40°C to +85°C, designed for precision clock generation in industrial microcontrollers and communication interfaces.
For engineers reviewing the 603-24-127JA4I datasheet, 603-24-127JA4I pinout, 603-24-127JA4I application, or 603-24-127JA4I equivalent, key selection considerations include load capacitance (12 pF), max ESR (90 Ω), aging (±5 ppm/yr), RoHS-compliant gold termination, and MSL1 reflow compatibility.
Technical Context
This 24 MHz fundamental-mode crystal operates with 12 pF load capacitance and supports stable oscillation in Pierce-type oscillator circuits. Its ±30 ppm frequency tolerance and stability are specified across the full −40°C to +85°C operating range, meeting industrial timing requirements.
The device uses AT-cut quartz with gold-plated terminations and exhibits low aging (±5 ppm/year) and low drive level sensitivity (≤0.1 mW), ensuring long-term frequency integrity in battery-powered and thermally variable environments.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ABM3B-24.000MHZ-D2Y-T | Same 24 MHz, 12 pF CL, but ±20 ppm tolerance and 70 Ω max ESR; 3.2 × 2.5 × 0.75 mm height | Better short-term stability; slightly lower profile may affect board-level mechanical clearance | Select when tighter initial calibration or reduced Z-height is prioritized over aging spec |
| ECX-32C24.000M | Same frequency and CL, but ±50 ppm tolerance, 100 Ω max ESR, and −30°C to +85°C range | Lower cost; wider tolerance and narrower low-temp limit reduce suitability for cold-start industrial use | Select for cost-sensitive consumer applications where −40°C operation is not required |
Compared with ABM3B-24.000MHZ-D2Y-T and ECX-32C24.000M, the 603-24-127JA4I provides balanced industrial-grade performance: tighter aging (±5 ppm/yr), full −40°C capability, and MSL1 process compatibility-making it optimal for long-lifecycle, thermally demanding embedded designs.

FAQ
What is the load capacitance requirement for the 603-24-127JA4I?
The 603-24-127JA4I requires a 12 pF load capacitance to operate at its nominal 24.000 MHz frequency. This value must be matched by the external capacitors in the oscillator circuit-typically two equal-value capacitors (e.g., 22 pF each) to ground, accounting for PCB stray capacitance. Deviations from 12 pF will shift the output frequency proportionally.
Is the 603-24-127JA4I suitable for reflow soldering per J-STD-020?
Yes, the 603-24-127JA4I is rated MSL1 and qualified for standard Pb-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. No pre-baking is required, and the device maintains parameter integrity after exposure, making it compatible with high-volume automated SMT assembly lines.
Does the 603-24-127JA4I support operation below −40°C?
No-the 603-24-127JA4I is specified for operation from −40°C to +85°C. Its frequency stability and ESR are guaranteed only within this range. Operation below −40°C may result in increased ESR, degraded startup reliability, or out-of-spec frequency deviation, and is not characterized or warranted by IDT.
What is the maximum recommended drive level for the 603-24-127JA4I?
The maximum recommended drive level for the 603-24-127JA4I is 0.1 mW. Exceeding this level accelerates aging and may cause activity dips or long-term frequency drift. Oscillator circuit design must ensure the crystal's effective power dissipation remains at or below this threshold under all operating conditions.
How does aging affect long-term performance of the 603-24-127JA4I?
Aging for the 603-24-127JA4I is specified at ±5 ppm per year maximum. This cumulative drift occurs due to material stress relaxation and electrode contamination over time. In systems requiring decade-level timing accuracy-such as utility metering or remote monitoring-the 603-24-127JA4I's low aging rate helps maintain synchronization without periodic hardware recalibration.
