Frequently Asked Questions (FAQ)

Q: Can the SG-8018CE 33.3333M-TJHSA0 directly replace the SG-310SCF 33.3333MB0?

A: Yes. Both parts share identical frequency (33.3333 MHz), CMOS output, frequency stability (±50ppm), 4-SMD No Lead package, and 3.20mm x 2.50mm dimensions. The substitute part operates within the original 3.3V supply specification and maintains compatible physical and electrical characteristics.

Q: What are the key differences between these parts?

A: The SG-8018CE 33.3333M-TJHSA0 extends the supply voltage range to 1.62V ~ 3.63V (versus fixed 3.3V), expands operating temperature to -40°C ~ 105°C (versus -20°C ~ 70°C), and features a slightly lower seated height (1.05mm versus 1.20mm). Maximum supply current increases from 4.5mA to 8.1mA.

Q: Are both parts RoHS compliant?

A: Yes. Both the SG-310SCF 33.3333MB0 and SG-8018CE 33.3333M-TJHSA0 are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does the substitute part require PCB layout modifications?

A: No. Both parts use identical 4-SMD, No Lead packaging with matching 3.20mm x 2.50mm footprints. The substitute part's lower seated height (1.05mm) is compatible with existing PCB designs.

Q: What is the product status of the substitute part?

A: The SG-8018CE 33.3333M-TJHSA0 is classified as Active, ensuring continued manufacturing and availability for new designs and production runs.
