Substitute Part Grouping Explanation

Substitution of the ASE-33.000MHZ-E-T is determined by strict equivalence in the following critical parameters:

Frequency: 33 MHz (exact match required) Output Type: CMOS (exact match required) Supply Voltage: 3.3V (exact match required) Function: Enable/Disable (exact match required) Package / Case: 4-SMD, No Lead (exact match required) Mounting Type: Surface Mount (exact match required) Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required) Height - Seated (Max): 0.047" (1.20mm) (exact match required) Current - Supply (Max): 13mA (exact match required) Current - Supply (Disable) (Max): 10µA (exact match required) Moisture Sensitivity Level (MSL): 1 (Unlimited) (exact match required) RoHS Status: ROHS3 Compliant (exact match required)

Parameters that may vary within acceptable substitution criteria include Frequency Stability and Operating Temperature range, provided all other electrical and mechanical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-33.000MHZ-E-T and ASE-33.000MHZ-L-C-T are Active products from Abracon LLC with identical electrical and mechanical specifications for core oscillator function. Selection between these parts is based on application-specific requirements:

The ASE-33.000MHZ-E-T operates within -20°C to 70°C with ±100ppm frequency stability and is suitable for standard industrial temperature range applications.

The ASE-33.000MHZ-L-C-T operates within -40°C to 85°C with ±50ppm frequency stability and is suitable for extended temperature range and higher frequency stability applications.

Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity classification. Mechanical compatibility is confirmed across all dimensional and mounting parameters.

Frequently Asked Questions (FAQ)

Q: Can ASE-33.000MHZ-L-C-T replace ASE-33.000MHZ-E-T in existing designs?

A: Yes. Both parts share identical electrical output characteristics (33 MHz CMOS), supply voltage (3.3V), enable/disable function, and mechanical package specifications (4-SMD, No Lead, 3.20mm x 2.50mm x 1.20mm). The ASE-33.000MHZ-L-C-T provides enhanced frequency stability (±50ppm vs ±100ppm) and extended operating temperature range (-40°C to 85°C vs -20°C to 70°C), making it suitable as a direct substitute.

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

A: Frequency stability and operating temperature range differ. The ASE-33.000MHZ-L-C-T offers tighter frequency tolerance (±50ppm) and wider temperature operation (-40°C to 85°C) compared to the ASE-33.000MHZ-E-T (±100ppm, -20°C to 70°C). All other specifications, including package, pinout, and electrical performance, are identical.

Q: Are the physical packages identical?

A: Yes. Both parts use 4-SMD, No Lead packaging with identical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.047" (1.20mm). PCB footprints and reflow profiles are compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and share the same HTSUS code (8542.39.0001). Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: Which part should be selected for high-temperature applications?

A: The ASE-33.000MHZ-L-C-T is specified for -40°C to 85°C operation and is appropriate for applications requiring extended temperature range. The ASE-33.000MHZ-E-T is limited to -20°C to 70°C.

Q: Which part should be selected for applications requiring tighter frequency tolerance?

A: The ASE-33.000MHZ-L-C-T provides ±50ppm frequency stability, compared to ±100ppm for the ASE-33.000MHZ-E-T. Selection depends on application frequency accuracy requirements.
