ASE-48.000MHZ-L-R-T Equivalent & Substitute Parts

Part Overview

The ASE-48.000MHZ-L-R-T is a 48 MHz crystal oscillator manufactured by Abracon LLC, designed for applications requiring a standard XO (Crystal Oscillator) with CMOS output and enable/disable functionality. This part operates at 3.3V supply voltage with ±25ppm frequency stability across an operating temperature range of -40°C to 85°C. The device is packaged in a 4-SMD, No Lead configuration with tape and reel packaging for automated assembly.

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility permits selection from qualified alternatives that maintain electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASE-48.000MHZ-L-R-T is determined by strict alignment with the following critical parameters:

Mandatory Compatibility Parameters:

• Frequency: 48 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)
• Physical Dimensions: 3.20mm x 2.50mm x 1.20mm max (exact match required)

Allowable Variation Parameters:

• Frequency Stability: ±25ppm to ±100ppm (wider tolerance acceptable)
• Operating Temperature Range: -40°C to 85°C (narrower range acceptable if application permits)
• Current Supply (Max): Up to 19mA (lower values acceptable)
• Current Supply (Disable): 10µA or lower (lower values acceptable)

Qualified substitutes maintain all mandatory parameters while permitting relaxation of frequency stability and operating temperature specifications where application requirements allow.

Parameter Comparison

Engineering Selection Recommendations

ASE-48.000MHZ-E-T (MFR Recommended): This Abracon LLC substitute maintains identical electrical specifications to the main part with the exception of frequency stability (±100ppm versus ±25ppm) and operating temperature range (-20°C to 70°C versus -40°C to 85°C). Selection of this part is appropriate for applications where the narrower temperature range and relaxed frequency stability are acceptable. All parts are ROHS3 compliant and carry Active product status.

ASE-48.000MHZ-L-C-T (MFR Recommended): This Abracon LLC substitute provides intermediate frequency stability (±50ppm) while maintaining the full operating temperature range (-40°C to 85°C) of the main part. This option offers a balance between the main part and the ASE-48.000MHZ-E-T variant. All electrical and mechanical parameters align with substitution requirements. ROHS3 compliance and Active product status are confirmed.

SXO32C3C481-48.000M (Direct Manufacturer): This Suntsu Electronics oscillator matches the main part's frequency stability (±25ppm) and operating temperature range (-40°C to 85°C). Current supply (Max) is 17mA, which is lower than the main part's 19mA specification. All mandatory electrical and mechanical parameters are compatible. ROHS3 compliance and Active product status are confirmed.

Frequently Asked Questions (FAQ)

Q: Can ASE-48.000MHZ-E-T be used as a direct replacement for ASE-48.000MHZ-L-R-T?

A: ASE-48.000MHZ-E-T is electrically compatible for applications where the operating temperature range of -20°C to 70°C and frequency stability of ±100ppm are acceptable. The narrower temperature specification and relaxed frequency tolerance represent the primary differences. Mechanical compatibility and all other electrical parameters are identical.

Q: What is the difference between ASE-48.000MHZ-L-C-T and the main part?

A: ASE-48.000MHZ-L-C-T differs only in frequency stability specification (±50ppm versus ±25ppm). The operating temperature range, current specifications, and all mechanical parameters remain identical. This part is suitable for applications where ±50ppm stability meets design requirements.

Q: Is SXO32C3C481-48.000M from a different manufacturer compatible?

A: SXO32C3C481-48.000M from Suntsu Electronics maintains all mandatory electrical and mechanical compatibility parameters. The maximum supply current is 17mA compared to 19mA for the main part. Frequency stability and operating temperature range match the main part specifications. Cross-manufacturer substitution is valid where supply chain requirements permit.

Q: What packaging differences exist between these parts?

A: ASE-48.000MHZ-L-R-T and ASE-48.000MHZ-E-T are supplied in Tape & Reel (TR) packaging. ASE-48.000MHZ-L-C-T is also supplied in Tape & Reel (TR) packaging. SXO32C3C481-48.000M is supplied in Bulk packaging. All parts share identical 4-SMD, No Lead package type and physical dimensions suitable for automated assembly.

Q: Are all substitute parts RoHS compliant?

A: All listed parts, including the main part and all substitutes, are ROHS3 compliant and carry Active product status. Moisture Sensitivity Level is 1 (Unlimited) for all Abracon parts. REACH status is Unaffected for all parts listed.
