ASE-8.000MHZ-L-R-T Equivalent & Substitute Parts

Part Overview

The ASE-8.000MHZ-L-R-T is an 8 MHz XO (Standard) CMOS oscillator manufactured by Abracon LLC, designed for applications requiring a 3.3V enable/disable function in a compact 4-SMD, No Lead surface mount package. The part is Active status and widely used in digital timing and clock generation circuits. Substitute parts may be required due to packaging availability, inventory constraints, or specific application packaging preferences while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution for the ASE-8.000MHZ-L-R-T is determined by strict equivalence across the following critical parameters:

• Frequency: 8 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, Height 0.047" max (exact match required)

The primary difference between the main part and its substitute is the packaging format: Tape & Reel (TR) versus Cut Tape (CT) & Digi-Reel®. Both formats contain electrically and mechanically identical components and are suitable for automated assembly processes. Frequency stability tolerance may vary between substitute options and should be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-8.000MHZ-L-R-T and ASE-8.000MHZ-L-C-T are Active status products from Abracon LLC with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on packaging format requirements and frequency stability tolerance specifications.

The ASE-8.000MHZ-L-R-T (Tape & Reel) is suitable for high-volume automated assembly operations where continuous reel feeding is standard. The ASE-8.000MHZ-L-C-T (Cut Tape & Digi-Reel®) provides flexibility for lower-volume production runs or mixed-component assembly scenarios.

The frequency stability difference (±25ppm versus ±50ppm) is the only electrical parameter variance. Applications with stringent frequency accuracy requirements should specify the ±25ppm tolerance part. Applications with relaxed frequency tolerance specifications may use either variant.

Frequently Asked Questions (FAQ)

Q: Can ASE-8.000MHZ-L-C-T be used as a direct replacement for ASE-8.000MHZ-L-R-T?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only: Tape & Reel versus Cut Tape & Digi-Reel®. PCB footprint, pinout, and electrical performance are identical.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place equipment in high-volume production. Cut Tape (CT) & Digi-Reel® packaging provides components in tape segments or alternative reel formats, suitable for lower-volume assembly or mixed-component runs.

Q: Does the frequency stability difference affect circuit compatibility?

A: Frequency stability tolerance (±25ppm versus ±50ppm) affects long-term frequency accuracy. Applications requiring precise frequency control should use the ±25ppm variant. Applications with relaxed frequency tolerance specifications can use either part.

Q: Are both parts RoHS compliant?

A: Yes. Both ASE-8.000MHZ-L-R-T and ASE-8.000MHZ-L-C-T are ROHS3 compliant.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

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

A: Yes, provided the design accommodates the frequency stability tolerance of the selected part. No circuit redesign is required for packaging format changes.
