Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASE-25.000MHZ-E-T is determined by strict equivalence in the following critical parameters:

• Frequency: 25 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm footprint (exact match required)

The substitute part ASE-25.000MHZ-L-C-T meets all critical electrical and mechanical parameters. Differences in frequency stability and operating temperature range represent performance enhancements rather than compatibility constraints, allowing this part to function as a direct substitute in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-25.000MHZ-E-T and ASE-25.000MHZ-L-C-T are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

The ASE-25.000MHZ-E-T is appropriate for applications with operating temperature requirements limited to -20°C to 70°C and frequency stability tolerance of ±100ppm.

The ASE-25.000MHZ-L-C-T provides enhanced performance specifications with extended operating temperature range (-40°C to 85°C) and improved frequency stability (±50ppm). This substitute is suitable for applications requiring operation across wider temperature extremes or tighter frequency tolerance specifications. Both parts maintain identical electrical output characteristics, current consumption, and physical form factor, ensuring direct compatibility in PCB layouts and circuit designs.

Frequently Asked Questions (FAQ)

Q: Can ASE-25.000MHZ-L-C-T replace ASE-25.000MHZ-E-T in existing designs?

A: Yes. Both parts share identical frequency, output type, supply voltage, enable/disable function, package type, and physical dimensions. The substitute part meets or exceeds all electrical specifications of the main part.

Q: What are the key differences between these two oscillators?

A: The ASE-25.000MHZ-L-C-T offers improved frequency stability (±50ppm versus ±100ppm) and extended operating temperature range (-40°C to 85°C versus -20°C to 70°C). All other electrical and mechanical parameters remain identical.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the same 4-SMD, No Lead package with identical 3.20mm x 2.50mm footprint and 1.20mm maximum height. PCB layouts, solder pad designs, and assembly processes require no modification.

Q: Do both parts require the same supply voltage and current handling?

A: Yes. Both oscillators operate at 3.3V supply with maximum current consumption of 13mA during normal operation and 10µA during disable mode. Power supply design and decoupling requirements remain unchanged.

Q: Which part should be selected for industrial temperature applications?

A: The ASE-25.000MHZ-L-C-T is specified for -40°C to 85°C operation, making it suitable for industrial temperature environments. The ASE-25.000MHZ-E-T is limited to -20°C to 70°C.
