Substitute Part Grouping Explanation

The FS32R274KSK2VMM qualifies as a direct substitute for the FS32R274KBK2VMM based on the following critical parameters:

• Identical core processor configuration: e200z4, e200z7 (2)
• Matching core size: 32-Bit Tri-Core
• Identical operating frequencies: 180MHz, 240MHz
• Identical program memory: 2MB FLASH (2M x 8)
• Identical EEPROM capacity: 64K x 8
• Identical RAM capacity: 1.5M x 8
• Identical voltage supply range: 1.19V ~ 5.5V
• Identical package: 257-LFBGA (14x14)
• Identical connectivity: CANbus, Ethernet, FlexRay, I2C, LINbus, SPI, ZipWire
• Identical peripherals: POR, PWM, WDT
• Identical operating temperature range: -40°C ~ 105°C (TA)

The primary difference is product status: the substitute part is Active, whereas the original is Obsolete. The packaging differs only in format (Tray vs. unspecified), which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FS32R274KSK2VMM is the direct substitute for the obsolete FS32R274KBK2VMM. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility. The substitute part carries Active product status, providing ongoing availability and manufacturer support.

The substitute part is ROHS3 compliant, whereas compliance status for the original part is not specified. The substitute part has a Moisture Sensitivity Level (MSL) of 3 (168 Hours) compared to MSL 1 (Unlimited) for the original. This difference requires adherence to appropriate moisture control procedures during storage and handling, as specified in IPC-A-610 standards for MSL 3 components.

For new designs and production transitions from the obsolete part, the FS32R274KSK2VMM provides full functional equivalence with improved regulatory compliance and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are the FS32R274KBK2VMM and FS32R274KSK2VMM pin-compatible?

A: Yes. Both parts use the identical 257-LFBGA (14x14) package with matching pinout, core processor configuration, and electrical specifications.

Q: What is the difference between these two parts?

A: The primary difference is product status. The FS32R274KBK2VMM is obsolete, while the FS32R274KSK2VMM is active. The substitute part is ROHS3 compliant and has an MSL rating of 3 (168 Hours) versus MSL 1 (Unlimited) for the original.

Q: Can I use FS32R274KSK2VMM as a direct replacement in existing designs?

A: Yes, the substitute part is electrically and mechanically equivalent. Existing PCB layouts, firmware, and system designs require no modification. Moisture handling procedures appropriate for MSL 3 components must be observed.

Q: What does MSL 3 (168 Hours) mean for the substitute part?

A: MSL 3 indicates the component must be used within 168 hours (7 days) of exposure to ambient conditions of 30°C and 85% relative humidity. Components must be stored in moisture-barrier packaging and baked according to IPC-A-610 standards if the time limit is exceeded.

Q: Is the substitute part available in the same packaging format?

A: The substitute part is supplied in Tray packaging, whereas the original packaging format is not specified. Both are surface-mount components in the 257-LFBGA package suitable for automated assembly.

Q: What is the ECCN classification for the substitute part?

A: The substitute part has ECCN 3A991A2, indicating it is subject to export control regulations. Verify compliance with applicable trade regulations for your jurisdiction and end-use application.
