Frequently Asked Questions (FAQ)

Q: Can CDC706PW directly replace CDC706PWG4 in existing designs? A: Yes. CDC706PW maintains identical electrical specifications, supply voltage range, operating temperature range, frequency capability, and 20-TSSOP package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between CDC706PW and CDCE706PW? A: Both parts are electrically and mechanically equivalent. The primary difference is product status: CDC706PW is designated "Not For New Designs," while CDCE706PW carries active status. For new designs, CDCE706PW is the preferred selection. For legacy system support, CDC706PW remains available.

Q: Are all substitute parts RoHS compliant? A: Yes. CDC706PWG4, CDC706PW, and CDCE706PW are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental standards.

Q: Does package compatibility extend to PCB layout? A: Yes. All three parts use the identical 20-TSSOP (0.173", 4.40mm Width) package, ensuring footprint and pinout compatibility on existing PCB designs.

Q: Are there any supply voltage or temperature derating considerations between substitutes? A: No. All substitute parts operate identically across the 3V to 3.6V supply range and -40°C to 85°C temperature range with no derating differences.
