Key Parameters

Substitute Part Grouping Explanation

Substitution of the F92500042 is determined by strict equivalence in the following critical parameters:

• Frequency: 25 MHz (exact match required)
• Frequency Tolerance: ±20ppm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C to 70°C (exact match required)
• Package / Case: 2-SMD, No Lead (exact match required)
• Physical Dimensions: 0.197" L x 0.126" W (5.00mm x 3.20mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

The following parameters may vary within acceptable engineering tolerances for substitution:

• Load Capacitance: 13pF to 20pF (circuit design dependent)
• ESR: 30 to 50 Ohms (circuit design dependent)
• Height - Seated: 1.30mm to 1.35mm (PCB assembly compatible)

All substitute parts listed maintain identical frequency, tolerance, stability, operating mode, temperature range, package type, and physical footprint as the original F92500042.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the F92500042 across critical parameters. Selection among substitute options is based on product status and compliance certifications:

CTS-Frequency Controls 445 Series (445C25B25M00000, 445C25C25M00000, 445C25D25M00000, 445C25E25M00000) parts are classified as Active products with ROHS3 compliance. These parts offer lower ESR values (40 Ohms) compared to the original F92500042 (50 Ohms) and provide load capacitance options ranging from 13pF to 20pF. The 445C25D25M00000 provides the closest electrical match with 18pF load capacitance identical to the original part.

The Abracon LLC ABM3-25.000MHZ-B2-T is classified as an Active product with ROHS3 compliance and offers the lowest ESR value (30 Ohms) among all substitutes. This part features 18pF load capacitance matching the original specification and a slightly reduced seated height of 1.30mm. REACH Affected status applies to this part.

All substitute parts are available in Tape & Reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 445C25B25M00000 (13pF load capacitance) be used as a direct replacement for the F92500042 (18pF load capacitance)?

A: Load capacitance differences require circuit design evaluation. The 445C25B25M00000 operates at 13pF versus the original 18pF specification. This parameter is circuit-dependent and must be validated against the oscillator circuit design to ensure frequency accuracy and startup characteristics remain within tolerance.

Q: What is the difference between the CTS 445 series parts and the Abracon ABM3 part?

A: The primary differences are ESR and load capacitance options. CTS 445 series parts offer ESR values of 40 Ohms with load capacitance options of 13pF, 16pF, 18pF, or 20pF. The Abracon ABM3-25.000MHZ-B2-T provides 30 Ohms ESR with 18pF load capacitance. All parts share identical frequency, tolerance, stability, operating temperature range, and physical package dimensions.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original F92500042 is RoHS compliant. Both certifications meet current environmental and hazardous substance restrictions.

Q: Can substitute parts be used interchangeably on existing PCBs designed for the F92500042?

A: Yes. All substitute parts maintain identical physical dimensions (0.197" L x 0.126" W / 5.00mm x 3.20mm), package type (2-SMD, No Lead), and mounting type (Surface Mount). The ABM3-25.000MHZ-B2-T has a slightly reduced seated height (1.30mm versus 1.35mm), which remains compatible with standard PCB assembly processes.

Q: Which substitute part should be selected for new designs?

A: Selection depends on circuit requirements and load capacitance specifications. The 445C25D25M00000 provides the closest electrical match with 18pF load capacitance and 40 Ohms ESR. The ABM3-25.000MHZ-B2-T offers lower ESR (30 Ohms) if circuit design permits. All parts are Active products with current manufacturing support.

Q: What is the inventory status of substitute parts?

A: 445C25B25M00000: 666 Pcs; 445C25C25M00000: 710 Pcs; 445C25D25M00000: 12,407 Pcs; 445C25E25M00000: 661 Pcs; ABM3-25.000MHZ-B2-T: 2,870 Pcs. All parts are available as New Original In Stock.
