Key Parameters

Substitute Part Grouping Explanation

Substitution of the UX72F62035 is determined by the following critical parameters:

• Frequency Match: 156.2578125 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Base Resonator Type: Crystal (exact match required)
• Oscillator Type: XO (Standard) (exact match required)
• Manufacturer Series: SaRonix-eCera™ UX (preferred for compatibility)
• RoHS and REACH Compliance: Required for regulatory alignment

The substitute part UX7BF62003 meets all critical substitution criteria while offering an Active product status and enhanced functionality through Enable/Disable capability.

Parameter Comparison

Engineering Selection Recommendations

The UX7BF62003 is the manufacturer-recommended substitute for the obsolete UX72F62035. Both components are manufactured by Diodes Incorporated within the same SaRonix-eCera™ UX series and share identical electrical specifications for frequency, output type, and supply voltage.

The UX7BF62003 offers the following advantages:

• Active Product Status: Currently in production with established supply chain availability (1151 Pcs in stock versus 758 Pcs for the obsolete part)
• Enhanced Compliance: ROHS3 Compliant certification provides alignment with current regulatory requirements
• Additional Functionality: Enable/Disable capability allows power management without requiring external switching
• Specified Performance Parameters: Frequency stability (±25ppm) and supply current specifications (70mA max, 100µA in disable mode) are documented

Both parts maintain identical operating temperature ranges (-40°C ~ 85°C), REACH compliance status, and LVPECL output characteristics. The substitute part is suitable for direct replacement in applications where the original UX72F62035 was specified.

Frequently Asked Questions (FAQ)

Q: Can the UX7BF62003 be used as a direct replacement for the UX72F62035?

A: Yes. Both parts operate at 156.2578125 MHz with LVPECL output at 3.3V supply voltage and share identical operating temperature ranges. The UX7BF62003 is the manufacturer-recommended substitute.

Q: What is the difference between the two parts?

A: The primary differences are product status (Obsolete vs. Active) and functionality. The UX7BF62003 includes Enable/Disable capability and provides documented frequency stability (±25ppm) and supply current specifications. Both parts are electrically equivalent for the core oscillator function.

Q: Are there any compatibility concerns with the Enable/Disable feature on the UX7BF62003?

A: The Enable/Disable function is an additional feature that does not affect compatibility. If the original design does not utilize this function, the UX7BF62003 operates as a standard oscillator. Designs that do not connect the enable pin will not be affected.

Q: Do both parts have the same physical dimensions?

A: The main part specifies dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm). The substitute part does not specify dimensions in the provided data. Physical compatibility should be verified against PCB layout requirements before implementation.

Q: What are the compliance differences between the two parts?

A: The UX72F62035 is RoHS Compliant; the UX7BF62003 is ROHS3 Compliant. Both maintain REACH Unaffected status. ROHS3 represents current regulatory alignment and is suitable for new designs and production runs.

Q: Which part should be selected for new designs?

A: The UX7BF62003 should be selected for new designs due to its Active product status, current compliance certifications, and established supply availability.
