Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBF550015 is determined by the following critical parameters that must remain consistent across equivalent parts:

• Frequency: 151.25 MHz (exact match required)
• Output Type: PECL (electrical interface compatibility)
• Supply Voltage: 2.5V (power supply compatibility)
• Package Dimensions: 0.276" L x 0.197" W / 7.00mm x 5.00mm (physical fit requirement)
• Operating Temperature Range: -40°C to 85°C (thermal specification)

The substitute part UX7BF55002 maintains these core electrical and mechanical parameters, enabling direct functional replacement in applications currently using the obsolete PBF550015.

Parameter Comparison

Engineering Selection Recommendations

The UX7BF55002 serves as the direct substitute for the obsolete PBF550015. Both components are manufactured by Diodes Incorporated and maintain identical electrical specifications for frequency, output type, and supply voltage. The substitute part carries Active product status, ensuring continued availability and manufacturing support. Both parts meet RoHS compliance requirements, with the substitute offering ROHS3 compliance. REACH compliance status is equivalent across both parts. Selection of the UX7BF55002 is appropriate for applications requiring replacement of the PBF550015 in existing designs or for new implementations requiring this frequency and output specification.

Frequently Asked Questions (FAQ)

Q: Can the UX7BF55002 directly replace the PBF550015 in existing designs?

A: Yes. Both parts share identical frequency (151.25 MHz), output type (PECL), supply voltage (2.5V), and operating temperature range (-40°C to 85°C). The electrical and mechanical compatibility enables direct substitution.

Q: What is the significance of the product status change from Obsolete to Active?

A: The PBF550015 is classified as Obsolete, indicating discontinued manufacturing. The UX7BF55002 maintains Active status, ensuring ongoing availability, manufacturing support, and compliance with current regulatory standards.

Q: Are there compliance differences between the two parts?

A: Both parts are REACH Unaffected. The substitute part carries ROHS3 Compliant status compared to RoHS Compliant for the original part, representing alignment with current regulatory requirements.

Q: What parameters must remain unchanged when selecting a substitute?

A: Frequency (151.25 MHz), output type (PECL), supply voltage (2.5V), package dimensions (7.00mm x 5.00mm), and operating temperature range (-40°C to 85°C) are the critical parameters determining substitution compatibility.

Q: Is the package size identical between both parts?

A: Package dimensions are specified as 0.276" L x 0.197" W (7.00mm x 5.00mm) for the PBF550015. Verify package specifications for the UX7BF55002 during component procurement to confirm physical fit in existing PCB layouts.
