Engineering Selection Recommendations
The MAX3674ECM2 is a direct functional equivalent to the obsolete MPC92433AE. Selection between these components should be based on the following factors:
Product Status: The MPC92433AE is obsolete. The MAX3674ECM2 carries Active product status, ensuring long-term availability and continued manufacturer support.
Compliance & Certifications: Both components share identical REACH, ECCN, and HTSUS classifications, confirming regulatory equivalence for procurement and export purposes. The MAX3674ECM2 additionally carries RoHS3 Compliance certification.
Inventory Availability: The MAX3674ECM2 is available in higher quantities (1645 Pcs) compared to the MPC92433AE (950 Pcs), supporting both immediate requirements and future production needs.
Packaging: Both components are supplied in 48-LQFP form factor with identical thermal and moisture sensitivity specifications, enabling direct PCB layout compatibility without redesign.
Frequently Asked Questions (FAQ)
Q: Can the MAX3674ECM2 directly replace the MPC92433AE on existing PCBs?
A: Yes. Both components share identical 48-LQFP package geometry, pinout configuration, supply voltage range (3.135V ~ 3.465V), operating temperature range (-40°C ~ 85°C), and functional specifications including PLL with bypass, LVCMOS/Crystal input, and LVPECL output. No PCB modifications are required.
Q: What is the frequency difference between these parts?
A: The MPC92433AE operates at a maximum frequency of 1.428GHz, while the MAX3674ECM2 operates at 1.36GHz. The MAX3674ECM2 frequency specification remains compatible with system requirements that do not mandate the full 1.428GHz capability of the original part.
Q: Are there any compliance or regulatory differences?
A: No. Both components share identical REACH, ECCN (EAR99), and HTSUS (8542.39.0001) classifications. The MAX3674ECM2 additionally carries RoHS3 Compliance certification, providing enhanced environmental compliance for new designs.
Q: What is the difference in packaging between the two parts?
A: Both components use 48-LQFP surface mount packages with 7x7mm dimensions. The MPC92433AE is supplied in standard packaging, while the MAX3674ECM2 is supplied in Tray packaging. Both maintain identical Moisture Sensitivity Level 3 (168 Hours) specifications.
Q: Why is the MPC92433AE listed as obsolete?
A: Obsolescence reflects the manufacturer's discontinuation of this product line. The MAX3674ECM2, with Active product status, represents the current equivalent offering from Microchip Technology and ensures continued availability for system support and new production.
