Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the 570BAC000804DG maintain identical electrical and mechanical parameters that define functional compatibility. Substitution is valid based on the following criteria:

Critical Parameters for Substitution:

• Frequency: 156.25 MHz (exact match required)
• Output: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (Reprogrammable) (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Current - Supply (Max): 108mA (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

The substitute parts 570BAB000118DG, 570BAB000544DG, and 570BAB001641DG are all members of the Si570 series and satisfy all critical electrical and mechanical parameters. These parts differ only in base product number designation (570BAB versus 570BAC) and certain compliance certifications, which do not affect functional performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts are active production components from Skyworks Solutions Inc. within the Si570 series. Selection between 570BAC000804DG and its substitutes should be based on the following factors:

Compliance Requirements: Parts 570BAB000118DG and 570BAB000544DG carry explicit ROHS3 Compliant and REACH Unaffected certifications. If your application or regional market requires these compliance certifications, these parts are preferred. The 570BAC000804DG and 570BAB001641DG do not specify these certifications in the provided data.

Inventory Availability: 570BAB000544DG has the highest inventory level at 110,121 pieces. 570BAB000118DG and 570BAB001641DG have moderate inventory at 1,279 and 1,030 pieces respectively. The main part 570BAC000804DG has 832 pieces available.

Functional Equivalence: All parts are functionally identical for circuit design purposes. PCB layout, schematic integration, and electrical performance will be equivalent across all four part numbers.

Frequently Asked Questions (FAQ)

Q: Can I substitute 570BAB000118DG for 570BAC000804DG in my design?

A: Yes. Both parts are electrically and mechanically identical. They share the same frequency (156.25 MHz), output type (LVDS), supply voltage (3.3V), package (8-SMD, No Lead), and all other critical parameters. No circuit redesign is required.

Q: What is the difference between the 570BAC and 570BAB base product numbers?

A: The base product number designation differs, but this does not affect electrical performance or physical compatibility. Both are Si570 series oscillators with identical specifications for the 156.25 MHz LVDS configuration.

Q: Are there any differences in current consumption between these parts?

A: The maximum supply current is 108mA for all parts. Part 570BAB000544DG additionally specifies a disable mode current of 75mA maximum, which is not specified for the other parts. This does not affect substitution compatibility.

Q: Do I need to update my PCB layout if I switch to a substitute part?

A: No. All parts use the same 8-SMD, No Lead package with identical dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm). PCB footprints and layouts are directly compatible.

Q: Which substitute part should I choose if compliance certifications are important?

A: If ROHS3 compliance and REACH unaffected status are required, select either 570BAB000118DG or 570BAB000544DG, as both explicitly carry these certifications in their specifications.

Q: Are all parts suitable for the same operating temperature range?

A: Yes. All four parts operate across the identical temperature range of -40°C to 85°C.
