Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBC500002 is based on the following critical parameters:

• Frequency Match: 125 MHz (exact match required)
• Output Standard Compatibility: PECL or LVPECL (low-voltage variant of PECL, electrically compatible)
• Supply Voltage: 3.3V (exact match required)
• Physical Footprint: 7.00mm x 5.00mm (same package dimensions)
• Manufacturer: Diodes Incorporated (same manufacturer ecosystem)

The UX7BC50001 qualifies as a substitute because it maintains the same frequency, supply voltage, and physical dimensions while offering LVPECL output (a compatible low-voltage derivative of PECL) with enhanced operating temperature range and active product status.

Parameter Comparison

Engineering Selection Recommendations

The UX7BC50001 is the recommended substitute for the obsolete PBC500002 based on the following engineering criteria:

• Frequency Equivalence: Both components operate at 125 MHz, ensuring direct functional compatibility in clock distribution and timing applications.
• Output Standard Compatibility: LVPECL is a low-voltage variant of PECL with electrical compatibility at 3.3V supply. LVPECL receivers are designed to accept PECL-level signals, making this substitution viable for existing circuit designs.
• Supply Voltage Match: Identical 3.3V supply requirement eliminates power distribution modifications.
• Physical Compatibility: Matching 7.00mm x 5.00mm footprint allows direct PCB placement without layout redesign.
• Active Product Status: The UX7BC50001 is currently in active production, ensuring long-term availability and supply chain stability.
• Enhanced Compliance: ROHS3 compliance exceeds the RoHS Compliant status of the original part, meeting current regulatory requirements.
• Extended Operating Range: The -40°C ~ 85°C operating temperature range of the UX7BC50001 provides broader environmental coverage compared to the PBC500002's -20°C ~ 70°C range.

Frequently Asked Questions (FAQ)

Q: Can LVPECL output directly replace PECL output in existing designs?

A: Yes. LVPECL is a low-voltage variant of PECL designed for 3.3V operation. LVPECL outputs are electrically compatible with PECL receivers at 3.3V supply voltage. The UX7BC50001 operates within the same voltage domain as the PBC500002, ensuring signal integrity and compatibility.

Q: Are the physical dimensions identical between PBC500002 and UX7BC50001?

A: Yes. Both components share the same footprint of 0.276" L x 0.197" W (7.00mm x 5.00mm), allowing direct PCB placement without layout modifications.

Q: What is the difference between the operating temperature ranges?

A: The PBC500002 operates from -20°C ~ 70°C, while the UX7BC50001 operates from -40°C ~ 85°C. The UX7BC50001 provides extended temperature coverage, making it suitable for applications requiring broader environmental tolerance.

Q: Why is the PBC500002 marked as Obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by Diodes Incorporated. The UX7BC50001, with active product status, is the current production equivalent within the SaRonix-eCera™ oscillator family.

Q: Are there any compliance differences between the two parts?

A: The PBC500002 is RoHS Compliant, while the UX7BC50001 is ROHS3 Compliant. Both are REACH Unaffected. ROHS3 represents the current regulatory standard, making the UX7BC50001 more suitable for new designs and long-term supply chain compliance.

Q: What is the package type for the UX7BC50001?

A: The UX7BC50001 is packaged as 6-SMD, No Lead with a maximum seated height of 0.061" (1.55mm), suitable for surface mount assembly processes.
