ASE-16.000MHZ-LC-T Equivalent & Substitute Parts

Part Overview

The ASE-16.000MHZ-LC-T is a 16 MHz crystal oscillator manufactured by Abracon LLC, designed for applications requiring a standard XO (Crystal Oscillator) with CMOS output and enable/disable functionality. This component operates at 3.3V supply voltage and is housed in a compact 4-SMD, No Lead surface mount package. The part is currently in active production status with 1797 units available in inventory.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple suppliers is needed to optimize procurement and supply chain resilience.

Substitute Part Grouping Explanation

Substitution of the ASE-16.000MHZ-LC-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Frequency: 16 MHz
Output Type: CMOS
Supply Voltage: 3.3V
Function: Enable/Disable capability
Frequency Stability: ±50ppm
Operating Temperature Range: -40°C ~ 85°C
Current - Supply (Max): 7mA
Package / Case: 4-SMD, No Lead
Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
Height - Seated (Max): 0.047" (1.20mm)
Mounting Type: Surface Mount

The substitute part LFSPXO025494 from IQD Frequency Products meets all mandatory matching parameters. The primary difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), which does not affect electrical or mechanical compatibility in the application circuit.

Engineering Selection Recommendations

ASE-16.000MHZ-LC-T (Abracon LLC):

Active product status with established supply chain
ROHS3 compliant and REACH unaffected
Available in Cut Tape and Digi-Reel® packaging formats
Suitable for applications requiring standard packaging options

LFSPXO025494 (IQD Frequency Products):

Active product status with higher inventory availability (8117 units)
ROHS3 compliant and REACH unaffected
Available in Tape & Reel (TR) packaging format
Suitable for high-volume production environments where reel packaging is standard

Both parts carry identical electrical specifications and mechanical dimensions. Selection between these parts should be based on packaging requirements, supplier preference, and procurement volume considerations. Both parts satisfy regulatory compliance requirements (ROHS3, REACH unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can LFSPXO025494 be used as a direct replacement for ASE-16.000MHZ-LC-T?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical frequency (16 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), current specifications, package type (4-SMD, No Lead), and physical dimensions (0.126" L x 0.098" W, 0.047" height). The only difference is packaging format (Cut Tape versus Tape & Reel).

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is used for smaller quantities and manual assembly operations. Tape & Reel (TR) packaging is used for automated high-volume production. Both formats contain the same component; the difference is in how the parts are supplied and handled during assembly.

Q: Are there any compatibility issues with PCB layout or schematic design?

A: No. Both parts use identical 4-SMD, No Lead package dimensions and pinout. PCB footprints, schematic symbols, and circuit connections remain unchanged between the two parts.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both ASE-16.000MHZ-LC-T and LFSPXO025494 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the frequency stability specification, and does it differ between parts?

A: Both parts specify ±50ppm frequency stability across the operating temperature range of -40°C ~ 85°C. This specification is identical for both components.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and mechanical specifications are equivalent. Existing designs using ASE-16.000MHZ-LC-T can incorporate LFSPXO025494 without circuit modifications or re-qualification, provided the packaging format change does not conflict with assembly equipment or procurement specifications.
