UX54A00002 Equivalent & Substitute Parts

Part Overview

The UX54A00002 is a 100 MHz XO (Standard) HCSL Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ UX series. This crystal oscillator operates at 3.3V with Enable/Disable functionality, housed in a 6-SMD, No Lead package. The device is Active in product status and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Alternative models are identified to support supply chain flexibility and inventory optimization while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the UX54A00002 is determined by strict equivalence across the following critical parameters:

Frequency matching at 100 MHz ensures signal integrity in target applications. Output type HCSL maintains compatibility with receiving circuits designed for this logic standard. Supply voltage of 3.3V is non-negotiable for power distribution and signal level compatibility. Enable/Disable functionality must be present to support power management requirements. Frequency stability of ±25ppm ensures timing accuracy within application tolerances. Operating temperature range of -40°C ~ 85°C defines the thermal operating envelope. Package type 6-SMD, No Lead with identical physical dimensions (5.00mm x 3.20mm) and height (1.35mm maximum) ensures PCB layout compatibility without redesign. Surface mount mounting type and RoHS3 compliance are mandatory for manufacturing and regulatory requirements.

The NX5041D0100.000000 meets all these criteria as a parametric equivalent within the SaRonix-eCera™ product family.

*Current specifications differ between parts. The NX5041D0100.000000 exhibits higher maximum supply current (70mA vs 40mA) and higher disable current (40mA vs 10µA). These differences do not prevent substitution in applications where power supply capacity and thermal management accommodate the higher current draw.

Engineering Selection Recommendations

Both the UX54A00002 and NX5041D0100.000000 are Active products from Diodes Incorporated with identical ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on:

Supply chain availability and lead time requirements. Current consumption characteristics relative to power budget constraints. Thermal design considerations, particularly in applications with limited heat dissipation. Existing inventory and procurement agreements with component distributors.

No technical redesign is required to substitute between these parts, provided the application power supply and thermal design accommodate the current consumption differences noted in the parameter comparison table.

Frequently Asked Questions (FAQ)

Q: Can the NX5041D0100.000000 be used as a direct replacement for the UX54A00002 on existing PCBs?

A: Yes. Both parts share identical package dimensions (5.00mm x 3.20mm), height (1.35mm), and 6-SMD, No Lead configuration. No PCB layout modifications are required for mechanical or electrical compatibility.

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

A: The primary differences are maximum supply current (UX54A00002: 40mA; NX5041D0100.000000: 70mA) and disable mode current (UX54A00002: 10µA; NX5041D0100.000000: 40mA). All other electrical and mechanical parameters are identical.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical MSL 1 (Unlimited) moisture sensitivity ratings. No compliance documentation changes are required for substitution.

Q: Which part should be selected for power-constrained applications?

A: The UX54A00002 exhibits lower maximum supply current (40mA) and significantly lower disable current (10µA), making it preferable for applications with strict power budgets or extended battery life requirements.

Q: Are both parts available in the same packaging format?

A: Yes. Both the UX54A00002 and NX5041D0100.000000 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
