Parameter Comparison

Engineering Selection Recommendations

The 545CAA62M5000ACG is the recommended substitute for the 545CAA62M5000ABG. The primary distinction is product lifecycle status: the main part is designated Not For New Designs, while the substitute maintains Active status within the same Ultra™ Si545 series. Both components demonstrate identical electrical and mechanical specifications, ensuring direct functional equivalence. The substitute part offers the advantage of ongoing manufacturer support and availability for both new designs and production continuity. Both parts maintain ROHS3 compliance and MSL Level 1 rating, supporting applications requiring environmental and regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the 545CAA62M5000ACG directly replace the 545CAA62M5000ABG in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including frequency, output type, supply voltage range, current consumption, package dimensions, and operating temperature range. No circuit modifications are required.

Q: What is the significance of the product status difference?

A: The main part (545CAA62M5000ABG) carries a Not For New Designs designation, indicating the manufacturer is transitioning away from this variant. The substitute (545CAA62M5000ACG) maintains Active status, ensuring continued availability and manufacturer support for both new production and design initiatives.

Q: Are the supply voltage specifications equivalent between the two parts?

A: Yes. The main part specifies 1.8V, 2.5V, 3.3V as discrete voltage options, while the substitute specifies 1.8V ~ 3.3V as a continuous range. Both support operation across the identical voltage envelope required for typical applications.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts maintain Moisture Sensitivity Level 1 (Unlimited) rating and ROHS3 compliance, supporting applications with equivalent environmental and regulatory requirements.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use identical 6-SMD, No Lead packaging with matching physical dimensions (0.276" L x 0.197" W / 7.00mm x 5.00mm) and maximum seated height (0.056" / 1.43mm), ensuring PCB layout and assembly compatibility.
