Product details

Overview

603-25-150JA4C8 from Integrated Device Technology (IDT) is a 25.000 MHz fundamental-mode quartz crystal resonator in a 3.2 × 2.5 × 1.0 mm JA4 CLCC package, with ±20 ppm frequency tolerance and stability over 0°C to +70°C, rated for 50 Ω max ESR and 8 pF load capacitance, used as a precision timing reference in microcontroller clock trees and USB-compliant peripheral interfaces.

For engineers reviewing the 603-25-150JA4C8 datasheet, 603-25-150JA4C8 pinout, 603-25-150JA4C8 application, or 603-25-150JA4C8 equivalent, key selection criteria include operating temperature range (0°C to +70°C), RoHS-compliant gold termination, MSL1 soldering profile, and compatibility with standard 8 pF load-capacitance oscillator circuits.

Technical Context

This is a passive two-terminal AT-cut quartz crystal resonator operating in fundamental mode at 25.000 MHz, designed for parallel-resonant oscillator configurations requiring 8 pF load capacitance. It exhibits low aging (±5 ppm/year) and tight thermal stability (±20 ppm over full operating range).

The JA4 ceramic leadless chip carrier (CLCC) package features gold-plated terminations, supports reflow soldering at 260°C for 10 seconds, and is rated Moisture Sensitivity Level 1 - indicating unlimited floor life under dry storage conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Frequency	25.000 MHz - precise fundamental oscillation frequency for synchronous digital timing.
Frequency Tolerance	±20 ppm at 25°C - ensures initial accuracy within 0.0005 ms deviation per second at room temperature.
Frequency Stability	±20 ppm over 0°C to +70°C - guarantees consistent timing across commercial-temperature embedded operation.
Load Capacitance	8 pF - requires external capacitors totaling 8 pF in parallel-resonant Pierce oscillator design.
ESR	50 Ω max - enables reliable start-up and stable oscillation with low-power CMOS oscillator circuits.
Aging	±5 ppm/year - limits long-term drift in time-critical applications such as real-time clocks or serial communication baud rate generation.

Pinout & Package

Package: 3.2 × 2.5 × 1.0 mm JA4 ceramic leadless chip carrier (CLCC) with gold-plated terminations, MSL1 rating, and RoHS-compliant Pb-free construction.

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, 3.2 × 2.5 mm footprint, but ±10 ppm tolerance and −20°C to +70°C range.	Higher initial accuracy; narrower temp range excludes extended commercial use cases.	Select when tighter initial calibration is prioritized over wide-temperature flexibility.
ECX-32-25.000M	Same frequency and package size, but ±30 ppm tolerance, 100 Ω ESR max, and −40°C to +85°C range.	Looser tolerance and higher ESR reduce oscillator margin; wider temp range suits harsher environments.	Choose only if operating below 0°C or above +70°C is required and circuit supports higher ESR.

Compared with ABM3B-25.000MHZ-D2Y-T and ECX-32-25.000M, the 603-25-150JA4C8 offers balanced performance: ±20 ppm tolerance and 0°C to +70°C range suit mainstream industrial and consumer designs, while its 50 Ω ESR and MSL1 rating ensure robust manufacturability and oscillator reliability without over-specifying cost or complexity.

FAQ

What is the operating temperature range specified for the 603-25-150JA4C8?

The 603-25-150JA4C8 is rated for an operating temperature range of 0°C to +70°C, as confirmed in the official IDT datasheet revision B. This range applies to frequency stability and electrical performance specifications. Storage temperature extends from −40°C to +85°C, but functional operation outside 0°C to +70°C is not guaranteed. The 603-25-150JA4C8 must be used within this commercial-grade envelope to meet its ±20 ppm stability specification.

Does the 603-25-150JA4C8 require external load capacitors, and if so, what value?

Yes, the 603-25-150JA4C8 requires external load capacitors totaling 8 pF in a standard Pierce oscillator configuration. This value is defined as the nominal load capacitance (CL) in the datasheet and must be matched by the sum of external capacitors plus PCB stray capacitance. Using incorrect CL values will shift the actual oscillation frequency away from 25.000 MHz. The 603-25-150JA4C8 itself does not integrate load capacitance.

Is the 603-25-150JA4C8 RoHS compliant and lead-free?

Yes, the 603-25-150JA4C8 is explicitly stated as RoHS compliant and Pb-free in the IDT datasheet. Its termination finish is gold, and it meets JEDEC J-STD-020 moisture sensitivity level 1 requirements. No lead-containing materials are used in the ceramic package, electrodes, or plating. The 603-25-150JA4C8 conforms to EU Directive 2011/65/EU and subsequent amendments.

What is the maximum drive level rating for the 603-25-150JA4C8, and why does it matter?

The 603-25-150JA4C8 has a maximum drive level rating of 0.3 mW. Exceeding this level risks accelerated aging, frequency drift, or crystal fracture due to excessive mechanical stress. Oscillator circuit design must limit power dissipation in the crystal using appropriate feedback resistor and inverter gain settings. Staying within 0.3 mW ensures the 603-25-150JA4C8 maintains its ±5 ppm/year aging spec and long-term reliability.

Can the 603-25-150JA4C8 be used in place of the 603-25-150JA4I variant?

No - the 603-25-150JA4C8 is rated for 0°C to +70°C operation, while the 603-25-150JA4I is qualified for −40°C to +85°C. Although both share identical frequency, ESR, and package, substituting the 603-25-150JA4C8 in extended-temperature applications violates its specified operating range and voids the ±20 ppm stability guarantee. The 603-25-150JA4C8 is not a drop-in replacement for the 603-25-150JA4I in industrial or automotive contexts.
