FH2400048 Equivalent & Substitute Parts

Part Overview

The FH2400048 is a 24 MHz crystal oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FH series. This surface mount crystal is designed for fundamental mode operation across industrial temperature ranges (-40°C to 85°C). The component is actively produced and widely used in timing and frequency control applications requiring precise 24 MHz reference signals. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FH2400048 is determined by the following critical parameters:

• Frequency Match: 24 MHz (exact)
• Frequency Stability: ±20ppm (exact)
• Operating Mode: Fundamental (exact)
• Operating Temperature Range: -40°C to 85°C (exact)
• Package Type: 4-SMD, No Lead (exact)
• Mounting Type: Surface Mount (exact)
• RoHS Compliance: ROHS3 Compliant (required)

The identified substitute parts maintain identical frequency, stability, operating mode, temperature range, package configuration, and RoHS compliance. Variations in load capacitance (10pF vs. 12pF) and ESR (100 Ohms vs. 60 Ohms) are within acceptable engineering tolerances for crystal oscillator applications and do not preclude functional equivalence when circuit design accommodates these parameter differences.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements. The ABM11-24.000MHZ-D2X-T3 (Abracon LLC) and LFXTAL069383 (IQD Frequency Products) are electrically and mechanically compatible with the FH2400048 for applications requiring 24 MHz fundamental mode operation across the -40°C to 85°C temperature range.

Selection between the main part and substitutes should be based on:

• Availability and lead time requirements
• Circuit design accommodation for load capacitance variation (10pF vs. 12pF)
• ESR tolerance in the application (60 Ohms vs. 100 Ohms)
• Supplier qualification and procurement policies
• Cost considerations

All three parts are suitable for direct substitution in 4-SMD surface mount applications with identical package footprints.

Frequently Asked Questions (FAQ)

Q: Can the ABM11-24.000MHZ-D2X-T3 directly replace the FH2400048?

A: Yes. Both parts operate at 24 MHz with ±20ppm stability in fundamental mode across -40°C to 85°C. The 4-SMD, No Lead package is identical. Load capacitance differs (10pF vs. 12pF) and ESR differs (100 Ohms vs. 60 Ohms), but these variations are within acceptable engineering tolerances for crystal oscillator circuits.

Q: What is the difference between the LFXTAL069383 and the FH2400048?

A: Both parts are 24 MHz crystals with ±20ppm stability, identical operating temperature range, and 4-SMD, No Lead packaging. The LFXTAL069383 has 10pF load capacitance and 100 Ohms ESR compared to the FH2400048's 12pF and 60 Ohms. Physical dimensions vary slightly (2.50mm x 2.00mm for both, but height differs: 0.70mm vs. 0.60mm).

Q: Are there any compliance differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 under export control regulations.

Q: Does load capacitance affect substitution compatibility?

A: Load capacitance is a circuit design parameter. The FH2400048 specifies 12pF while both substitutes specify 10pF. Circuit design must accommodate this difference. Consult oscillator circuit design specifications to confirm compatibility.

Q: What is the significance of ESR differences?

A: ESR (Equivalent Series Resistance) affects crystal startup time and power consumption. The FH2400048 has 60 Ohms ESR while substitutes have 100 Ohms. Higher ESR may require circuit design adjustment. Verify circuit specifications support 100 Ohms ESR operation.
