Substitute Part Grouping Explanation

Substitution of the SPC5604EEF1MLH is determined by strict equivalence across the following critical parameters:

• Core Architecture: e200z0h processor with 32-bit single-core configuration
• Memory Configuration: 512KB FLASH, 96KB RAM, 64KB EEPROM
• Clock Speed: 64MHz operation
• Voltage Range: 3V ~ 3.6V supply compatibility
• Peripheral Set: CANbus, Ethernet, I2C, LINbus, SCI, SPI connectivity
• I/O Count: 39 I/O pins
• Package: 64-LQFP (10x10) surface mount form factor
• Compliance: ROHS3 and REACH compliance status

Substitute parts maintain identical electrical and functional specifications. Variations in packaging type (Tray vs. Bulk) and product status (Active vs. Discontinued) do not affect electrical compatibility or functional operation.

Parameter Comparison

Engineering Selection Recommendations

SPC5604EEF2MLH is the primary direct substitute. This part maintains identical electrical and functional specifications to the SPC5604EEF1MLH while offering active product status and higher inventory availability (12,430 units). Both parts are ROHS3 compliant with matching MSL ratings. The packaging difference (Tray vs. unspecified) does not affect electrical compatibility.

SPC5603EEF2MLH is a parametric equivalent offering identical core functionality, memory configuration, and connectivity. Active product status and ROHS3 compliance align with the original part's compliance profile. Lower inventory (1,045 units) may impact lead time considerations.

SPC5604ESF2MLH is a parametric equivalent from Freescale Semiconductor with identical electrical specifications and memory configuration. Active product status supports long-term availability. Compliance documentation (RoHS and MSL) is not specified in available data; verification of regulatory compliance may be required for applications with strict compliance mandates.

Selection should prioritize SPC5604EEF2MLH for direct replacement due to active status, inventory availability, and confirmed compliance certifications. Alternative parts are suitable where supply constraints exist, provided compliance requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can SPC5604EEF2MLH directly replace SPC5604EEF1MLH in existing designs?

A: Yes. Both parts share identical electrical specifications, memory configuration, clock speed, voltage range, I/O count, and peripheral set. The 64-LQFP package and pin configuration are identical, enabling direct PCB-level substitution without design modification.

Q: What is the difference between SPC5604EEF1MLH and SPC5604EEF2MLH?

A: The parts are electrically and functionally identical. The primary difference is product status: SPC5604EEF1MLH is discontinued, while SPC5604EEF2MLH is active. Packaging type differs (unspecified vs. Tray), but this does not affect electrical operation or compatibility.

Q: Is SPC5603EEF2MLH compatible with designs using SPC5604EEF1MLH?

A: Yes. SPC5603EEF2MLH maintains identical core processor, memory configuration, clock speed, voltage range, I/O count, and peripheral connectivity. The 64-LQFP package and pin configuration are identical, supporting direct substitution.

Q: What does the packaging type (Tray vs. Bulk) mean for component selection?

A: Packaging type refers to the quantity and format of delivery (Tray for organized quantities, Bulk for loose components). This affects handling, storage, and logistics but does not alter electrical specifications or functional compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: SPC5604EEF2MLH and SPC5603EEF2MLH are confirmed ROHS3 compliant. SPC5604ESF2MLH compliance status is not specified in available documentation and should be verified if regulatory compliance is required.

Q: Can I use SPC5604ESF2MLH from Freescale Semiconductor as a substitute?

A: Yes, from an electrical and functional standpoint. SPC5604ESF2MLH maintains identical core specifications and memory configuration. However, verify compliance certifications (RoHS, REACH, MSL) with the supplier if your application requires specific regulatory compliance.

Q: What inventory considerations should guide part selection?

A: SPC5604EEF2MLH offers the highest inventory (12,430 units), supporting immediate availability. SPC5603EEF2MLH (1,045 units) and SPC5604ESF2MLH (1,083 units) have lower stock levels. For time-sensitive applications, prioritize SPC5604EEF2MLH.
