Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPPFXC8L-A7BP-44.736TS is determined by the following critical parameters:

• Frequency Match: 44.736 MHz (exact)
• Output Configuration: CMOS
• Supply Voltage: 3.3V
• Enable/Disable Function: Required
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Mounting Type: Surface Mount
• RoHS Compliance: Required

The substitute part 510CCA44M7360AAGR manufactured by Skyworks Solutions Inc. satisfies all mandatory substitution criteria. Both parts operate at the identical frequency with matching voltage supply, output type, and functional enable/disable capability across the same temperature range. Both are RoHS compliant and surface mount devices.

Parameter Comparison

Engineering Selection Recommendations

The 510CCA44M7360AAGR from Skyworks Solutions Inc. is an active product with full RoHS compliance and superior moisture sensitivity rating (MSL 1 vs. MSL 2). The substitute part delivers tighter frequency stability (±20ppm vs. ±45ppm) and improved disable mode current performance (18mA vs. 50µA), representing enhanced electrical characteristics.

Physical package differences exist: the Skyworks part uses a smaller 4-SMD no-lead package (7.00mm x 5.00mm x 1.80mm) compared to the Cardinal 4-SOJ package (14.50mm x 8.80mm x 4.70mm). PCB layout and footprint modifications are required for implementation.

Both parts maintain identical frequency, voltage supply, output type, and functional enable/disable capability. The substitute part's active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 510CCA44M7360AAGR directly replace the CPPFXC8L-A7BP-44.736TS without design changes?

A: Electrical substitution is valid. Both parts operate at 44.736 MHz with 3.3V supply, CMOS output, and enable/disable function. However, physical package differences require PCB footprint redesign. The Skyworks part uses a smaller 4-SMD no-lead package versus the Cardinal 4-SOJ package.

Q: What are the key differences between these two oscillators?

A: Frequency stability is tighter in the Skyworks part (±20ppm vs. ±45ppm). Disable mode current is lower (18mA vs. 50µA). Moisture sensitivity is superior (MSL 1 unlimited vs. MSL 2 one year). Physical dimensions are significantly smaller. Supply current in active mode is comparable (26mA vs. 25mA).

Q: Is the substitute part RoHS compliant?

A: Yes, the 510CCA44M7360AAGR is RoHS compliant, matching the compliance status of the original part.

Q: What is the impact of the different package types?

A: The 4-SOJ package (7.62mm pitch) differs from the 4-SMD no-lead package. PCB layout, footprint, and assembly process require modification. Component placement density may improve due to the smaller footprint of the Skyworks part.

Q: Are there any supply chain considerations?

A: The CPPFXC8L-A7BP-44.736TS is obsolete. The 510CCA44M7360AAGR is an active product with established supply availability, supporting long-term production continuity.
