PXC500008 Equivalent & Substitute Parts

Part Overview

The PXC500008 is a 125 MHz XO (Standard) LVDS Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ PX series. This surface mount crystal oscillator operates at 3.3V with enable/disable functionality and is housed in a 6-SMD, No Lead package. The device is currently in active production status with 970 pieces available in new original inventory.

Alternative models become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component substitution within equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PXC500008 is determined by strict alignment of the following parameters:

• Frequency: 125 MHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Enable/Disable Function: Present (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Physical Footprint: 7.00mm x 5.00mm (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature: -20°C ~ 70°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The SXO75L3C271-125.000M from Suntsu Electronics, Inc. meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

*Compatible: SXO75L3C271-125.000M operates within acceptable parameters. Higher supply current (60mA vs 47mA) and lower seated height (1.70mm vs 2.00mm) do not prevent substitution in standard applications.

Engineering Selection Recommendations

Both the PXC500008 and SXO75L3C271-125.000M are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability and lead time requirements
• Supply chain preferences and established vendor relationships
• Current inventory levels (PXC500008: 970 pcs; SXO75L3C271-125.000M: 4739 pcs)
• PCB assembly process compatibility with the 1.70mm vs 2.00mm height difference

Both components are suitable for direct substitution in applications requiring 125 MHz LVDS oscillation with 3.3V supply and enable/disable control.

Frequently Asked Questions (FAQ)

Q: Can SXO75L3C271-125.000M replace PXC500008 in existing designs?

A: Yes. Both parts share identical electrical specifications (125 MHz, LVDS output, 3.3V supply, ±25ppm stability, -20°C to 70°C operation) and the same 6-SMD, No Lead package footprint (7.00mm x 5.00mm). The SXO75L3C271-125.000M has a lower seated height (1.70mm vs 2.00mm), which is compatible with standard PCB assembly processes.

Q: What is the difference in supply current between these parts?

A: The PXC500008 specifies a maximum supply current of 47mA, while the SXO75L3C271-125.000M specifies 60mA. This difference does not prevent substitution; the higher current specification of the Suntsu part is within acceptable operating margins for typical 3.3V supply designs.

Q: Are both parts RoHS compliant?

A: Yes. Both the PXC500008 and SXO75L3C271-125.000M are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available?

A: The PXC500008 is available in tape and reel packaging. The SXO75L3C271-125.000M is available in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Are there any frequency or stability differences?

A: No. Both parts operate at exactly 125 MHz with ±25ppm frequency stability and identical enable/disable functionality.
