Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 403WF24012IMR is determined by strict alignment of the following critical parameters: frequency (24 MHz), frequency tolerance (±10ppm), load capacitance (4pF), operating temperature range (-40°C to 85°C), operating mode (Fundamental), package type (4-SMD, No Lead), and mounting configuration (Surface Mount). All identified substitute parts meet these core electrical and mechanical requirements. Variations in ESR and physical dimensions are permitted within the constraints of the 4-SMD, No Lead package family, as these do not compromise functional compatibility in standard crystal oscillator circuit applications. All substitute parts maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

ABM8W-24.0000MHZ-4-D1X-T3 is the parametric equivalent to 403WF24012IMR, matching all critical electrical specifications including 50 Ohms ESR and identical package dimensions (3.20mm x 2.50mm). This part is recommended as the primary substitute when direct replacement is required without design modification. Both parts maintain identical form factor and height characteristics, enabling direct PCB layout compatibility.

ABM10W-24.0000MHZ-4-D1X-T3 and ABM11W-24.0000MHZ-4-D1X-T3 are functionally compatible alternatives with higher ESR values (80 Ohms and 100 Ohms respectively) and reduced package dimensions. These parts are suitable for applications where circuit design accommodates higher ESR characteristics and where compact form factor provides design advantages. Both maintain full electrical compatibility across frequency, tolerance, load capacitance, and temperature specifications.

All substitute parts carry Active product status, ROHS3 compliance, and REACH Unaffected designation, meeting current regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can ABM10W-24.0000MHZ-4-D1X-T3 or ABM11W-24.0000MHZ-4-D1X-T3 be used as direct drop-in replacements for 403WF24012IMR?

A: ABM10W and ABM11W parts are electrically compatible but feature different package dimensions and higher ESR values. ABM10W measures 2.50mm x 2.00mm (versus 3.20mm x 2.50mm) with 80 Ohms ESR, and ABM11W measures 2.00mm x 1.60mm with 100 Ohms ESR. These differences require circuit design verification and potential PCB layout modification. ABM8W-24.0000MHZ-4-D1X-T3 is the true direct replacement with identical dimensions and ESR.

Q: What is the significance of ESR variation among these parts?

A: ESR (Equivalent Series Resistance) affects crystal oscillator circuit performance, particularly startup behavior and drive level. The 403WF24012IMR and ABM8W both specify 50 Ohms ESR. ABM10W (80 Ohms) and ABM11W (100 Ohms) require circuit design confirmation to ensure oscillator stability and proper frequency accuracy within the specified ±10ppm tolerance. Higher ESR may increase power consumption and affect startup time.

Q: Are all substitute parts available in the same packaging format?

A: All parts are supplied in Tape & Reel (TR) packaging for automated assembly. However, physical package dimensions differ: 403WF24012IMR and ABM8W share 3.20mm x 2.50mm dimensions, ABM10W measures 2.50mm x 2.00mm, and ABM11W measures 2.00mm x 1.60mm. PCB footprint compatibility must be verified before substitution.

Q: Do these parts meet the same regulatory and compliance standards?

A: All parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under export control regulations. Compliance profiles are equivalent across all listed parts.

Q: What is the difference between Frequency Tolerance and Frequency Stability?

A: Frequency Tolerance (±10ppm) specifies the initial accuracy at room temperature during manufacturing. Frequency Stability (±20ppm) defines the maximum frequency variation across the full operating temperature range (-40°C to 85°C). All listed parts meet identical specifications for both parameters.
