Key Parameters

Substitute Part Grouping Explanation

The ASE-33.333MHZ-L-C-T qualifies as a substitute based on the following critical parameters:

Electrical compatibility is maintained through identical frequency (33.333 MHz), output type (CMOS), supply voltage (3.3V), and enable/disable function. The maximum supply current (13mA) and disable current (10µA) remain unchanged.

Mechanical compatibility is confirmed through identical package type (4-SMD, No Lead), physical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm), and seated height (0.047" / 1.20mm).

Compliance and environmental specifications remain consistent: both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) rating.

The substitute part differs in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and offers improved frequency stability (±50ppm versus ±100ppm) and extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-33.333MHZ-E-T and ASE-33.333MHZ-L-C-T are Active products from Abracon LLC with full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on application requirements and supply chain considerations.

The ASE-33.333MHZ-E-T is suitable for applications with standard operating temperature requirements (-20°C ~ 70°C) and standard frequency stability tolerance (±100ppm).

The ASE-33.333MHZ-L-C-T provides enhanced performance characteristics with extended operating temperature range (-40°C ~ 85°C) and improved frequency stability (±50ppm), making it appropriate for applications requiring tighter timing specifications or operation in wider temperature environments. The alternative packaging format (Cut Tape & Digi-Reel®) may influence procurement and assembly logistics.

Both parts maintain identical electrical performance in terms of supply current, disable current, and functional operation, ensuring direct substitution capability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can ASE-33.333MHZ-L-C-T be used as a direct replacement for ASE-33.333MHZ-E-T?

A: Yes. Both parts share identical frequency (33.333 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, package type (4-SMD, No Lead), physical dimensions, and current specifications. The parts are electrically and mechanically interchangeable.

Q: What are the differences between these two parts?

A: The primary differences are packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), frequency stability (±100ppm versus ±50ppm), and operating temperature range (-20°C ~ 70°C versus -40°C ~ 85°C). The substitute part offers improved stability and wider temperature operation.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects supply chain and assembly handling only. Once mounted on the PCB, both parts perform identically in the circuit.

Q: Are both parts RoHS compliant?

A: Yes. Both ASE-33.333MHZ-E-T and ASE-33.333MHZ-L-C-T are ROHS3 Compliant and REACH Unaffected.

Q: Which part should I select for a temperature-critical application?

A: For applications requiring operation beyond -20°C ~ 70°C, the ASE-33.333MHZ-L-C-T with its -40°C ~ 85°C operating range is the appropriate selection.

Q: Which part should I select for timing-critical applications?

A: For applications requiring tighter frequency tolerance, the ASE-33.333MHZ-L-C-T with ±50ppm stability is the appropriate selection compared to the ±100ppm of the ASE-33.333MHZ-E-T.
