Key Parameters

Substitute Part Grouping Explanation

Substitution of the F62500047 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Frequency: 25 MHz (exact match required)
• Frequency Tolerance: ±20ppm (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 2-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variations:

• ESR (Equivalent Series Resistance): 30 to 50 Ohms (within acceptable operating range)
• Physical dimensions: Minor variations permitted within SMD package tolerances
• Packaging format: Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR) formats are interchangeable

All substitute parts listed below meet these criteria and are qualified for direct replacement in applications designed for the F62500047.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (18pF Load Capacitance - Exact Match):

The 445I23D25M00000 (CTS-Frequency Controls), ABM3-25.000MHZ-D2Y-T (Abracon LLC), ECS-250-18-23A-JGN-TR (ECS Inc.), and H130A-25.000-18-F-2030-EXT-TR (Raltron Electronics) are direct functional equivalents with identical 18pF load capacitance. All are active production parts with ROHS3 compliance. The 445I23D25M00000 offers the highest inventory availability (253,883 pcs) and lowest ESR at 40 Ohms. The ABM3-25.000MHZ-D2Y-T and ECS-250-18-23A-JGN-TR feature 30 Ohms ESR, providing improved performance margin. Selection among these should be based on supply chain availability, packaging format preference (Tape & Reel vs. Cut Tape), and circuit design requirements for ESR characteristics.

Secondary Substitutes (Alternate Load Capacitance):

The 445I23C25M00000 (16pF), 445I23B25M00000 (13pF), and 445I23E25M00000 (20pF) are suitable only when circuit design specifications permit load capacitance variation. These parts maintain identical frequency, tolerance, stability, and temperature range but require circuit validation to confirm compatibility with the application's oscillator design.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute crystal with different load capacitance (13pF, 16pF, or 20pF) instead of 18pF?

A: Load capacitance directly affects oscillator frequency calibration. Substitution with alternate load capacitance values (445I23B25M00000 at 13pF, 445I23C25M00000 at 16pF, or 445I23E25M00000 at 20pF) is only permissible if your circuit design explicitly supports these values. Verify oscillator circuit documentation and perform frequency validation testing before deployment.

Q: What is the significance of ESR differences between substitute parts?

A: ESR (Equivalent Series Resistance) affects crystal startup characteristics and power consumption. The F62500047 specifies 50 Ohms ESR. Substitute parts with lower ESR values (30 to 40 Ohms) provide improved startup margin and reduced power draw. This represents a performance enhancement and does not create compatibility issues.

Q: Are Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging formats interchangeable?

A: Both packaging formats contain identical components and are mechanically compatible with standard SMD assembly equipment. Selection between formats depends on production volume, handling equipment capability, and supply chain logistics. No electrical or functional differences exist between packaging formats.

Q: Why is the F62500047 listed as obsolete?

A: Obsolete status indicates the manufacturer (Diodes Incorporated) has discontinued production. Active substitute parts from CTS-Frequency Controls, Abracon LLC, ECS Inc., and Raltron Electronics provide equivalent functionality with ongoing manufacturing support and improved compliance certifications (ROHS3).

Q: Do all substitute parts meet the same temperature and compliance requirements?

A: All listed substitutes maintain the -40°C to 85°C operating temperature range and ±20ppm frequency tolerance. All active production substitutes carry ROHS3 compliance. The original F62500047 carries RoHS Compliant status. Verify specific REACH and ECCN requirements for your application and supply chain.

Q: Can I mix different substitute part numbers in the same production batch?

A: Yes, all listed 18pF load capacitance substitutes (445I23D25M00000, ABM3-25.000MHZ-D2Y-T, ECS-250-18-23A-JGN-TR, H130A-25.000-18-F-2030-EXT-TR) are functionally equivalent and can be used interchangeably within the same design. However, maintain consistent part selection within individual production runs to simplify traceability and quality documentation.
