Substitute Part Grouping Explanation

Substitution eligibility for the SI5374C-A-BL is determined by strict alignment across the following critical parameters:

• Maximum frequency: 808MHz
• Number of circuits: 4
• Output format support: CML, LVCMOS, LVDS, LVPECL
• Supply voltage range: 1.71V ~ 2.75V
• Operating temperature range: -40°C ~ 85°C
• Package type: 80-LBGA
• Mounting type: Surface Mount
• Base product series: SI5374

The SI5374C-A-GL meets all electrical and mechanical substitution criteria. This part shares identical functional specifications, output configurations, and thermal operating parameters. The primary distinction lies in product lifecycle status and RoHS compliance certification, which may influence design qualification and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The SI5374C-A-BL is the preferred selection for new designs due to its Active product status, which ensures long-term manufacturer support and availability. This part is suitable for applications where RoHS non-compliance is acceptable within the design and regulatory framework.

The SI5374C-A-GL serves as a functional equivalent for existing designs or applications where ROHS3 compliance is a requirement. However, this part carries a "Not For New Designs" designation, indicating that Skyworks Solutions Inc. is transitioning away from this variant. Selection of the SI5374C-A-GL should be limited to legacy system support, retrofit applications, or situations where RoHS3 certification is mandatory and the SI5374C-A-BL cannot be qualified.

Both parts are electrically and mechanically interchangeable within the specified operating parameters. PCB layout, thermal management, and signal integrity considerations remain identical between the two variants.

Frequently Asked Questions (FAQ)

Q: Are SI5374C-A-BL and SI5374C-A-GL pin-for-pin compatible?

A: Yes. Both parts use the 80-LBGA package with identical pinout, supply voltage requirements, and output signal specifications. Direct substitution on the PCB is possible without layout modifications.

Q: What is the difference between SI5374C-A-BL and SI5374C-A-GL?

A: The primary differences are product lifecycle status and RoHS compliance. The SI5374C-A-BL is Active and RoHS non-compliant. The SI5374C-A-GL is designated "Not For New Designs" and is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Can I use SI5374C-A-GL in a new design?

A: While electrically and mechanically equivalent, the SI5374C-A-GL carries a "Not For New Designs" status. New designs should prioritize the SI5374C-A-BL. Use of SI5374C-A-GL in new designs may result in future availability constraints and reduced manufacturer support.

Q: What does "Not For New Designs" mean?

A: This designation indicates that the manufacturer is phasing out this part variant. While existing inventory may be available, long-term supply cannot be guaranteed. New product development should use the Active variant (SI5374C-A-BL) to ensure sustained availability and support.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate within the same temperature range (-40°C ~ 85°C) and deliver identical frequency performance (808MHz maximum). Thermal management and performance characteristics are equivalent.

Q: What is the MSL rating for both parts?

A: Both SI5374C-A-BL and SI5374C-A-GL have an MSL rating of 3 (168 Hours), indicating identical moisture sensitivity and handling requirements.

Q: Which part should I select for RoHS-compliant applications?

A: The SI5374C-A-GL is ROHS3 compliant. However, due to its "Not For New Designs" status, consult with Skyworks Solutions Inc. regarding long-term availability and alternative RoHS-compliant solutions within the SI5374 series.
