Substitute Part Grouping Explanation

Substitute parts for the ASE-18.432MHZ-L-R-T must maintain compatibility across the following critical parameters:

Frequency matching at 18.432 MHz is mandatory for all substitutes. Output type must remain CMOS to ensure signal integrity with existing circuit designs. Supply voltage of 3.3V is required for direct replacement without circuit modification. Enable/Disable functionality must be preserved to maintain power management capabilities. Package type (4-SMD, No Lead) and physical dimensions (3.20mm x 2.50mm, 1.20mm maximum height) ensure mechanical compatibility with PCB layouts and assembly processes. Operating temperature range (-40°C to 85°C) and supply current specifications (7mA maximum, 10µA disable mode) must be met or exceeded. RoHS3 compliance and MSL Level 1 rating are required for regulatory and manufacturing compatibility.

The identified substitute ASE-18.432MHZ-L-C-T meets all mandatory compatibility criteria while offering alternative frequency stability characteristics suitable for different application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-18.432MHZ-L-R-T and ASE-18.432MHZ-L-C-T are Active status products from Abracon LLC with full ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001). The primary distinction between these parts is frequency stability: the main part offers ±25ppm stability, while the substitute provides ±50ppm stability. Selection between these parts depends on application-specific frequency accuracy requirements. Both parts are suitable for direct PCB substitution without layout or assembly modifications due to identical package specifications and electrical characteristics. Compliance certifications and moisture sensitivity ratings are equivalent, ensuring manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can ASE-18.432MHZ-L-C-T replace ASE-18.432MHZ-L-R-T in existing designs?

A: Yes, direct substitution is possible. Both parts share identical frequency, output type, supply voltage, package dimensions, and operating temperature range. The frequency stability difference (±50ppm vs ±25ppm) is the only electrical distinction and must be evaluated against application requirements.

Q: What is the difference between the two part numbers?

A: The parts differ in frequency stability specification. ASE-18.432MHZ-L-R-T provides ±25ppm stability, while ASE-18.432MHZ-L-C-T provides ±50ppm stability. All other electrical and mechanical parameters are identical.

Q: Are the packages physically identical?

A: Yes. Both parts use 4-SMD, No Lead packaging with dimensions of 3.20mm x 2.50mm and maximum height of 1.20mm. PCB footprints and assembly processes are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Moisture sensitivity level is 1 (Unlimited) for both.

Q: Which part should I select for my application?

A: Selection depends on frequency accuracy requirements. Applications requiring tighter frequency tolerance should use ASE-18.432MHZ-L-R-T (±25ppm). Applications with less stringent frequency accuracy can use ASE-18.432MHZ-L-C-T (±50ppm).

Q: Are there any supply current differences?

A: No. Both parts have identical maximum supply current (7mA) and disable mode current (10µA) specifications.
