Substitute Part Grouping Explanation

Substitution eligibility for the LFXP2-40E-5F484C is determined by strict equivalence across the following critical parameters:

• Logic element count: 40,000
• I/O pin count: 363
• RAM capacity: 906,240 bits
• Package designation: 484-BBGA
• Supply voltage range: 1.14V ~ 1.26V
• Operating temperature range: 0°C ~ 85°C
• Mounting configuration: Surface Mount

The LFXP2-40E-5FN484C meets all substitution criteria. The primary distinction between the main part and its substitute is the packaging format (tray versus bulk) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The LFXP2-40E-5FN484C is the direct functional equivalent of the LFXP2-40E-5F484C. Both devices share identical electrical specifications, logic capacity, I/O configuration, and thermal operating range.

The LFXP2-40E-5FN484C is classified as active product status, ensuring continued availability and manufacturing support. This part carries ROHS3 compliance certification, whereas the original part is non-compliant. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Are the LFXP2-40E-5F484C and LFXP2-40E-5FN484C pin-compatible?

A: Yes. Both parts use the 484-BBGA package with identical pin assignments, I/O count (363), and electrical specifications. Direct PCB-level substitution is supported.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete versus active) and packaging format (bulk versus tray). The electrical and functional specifications are identical.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance status reflects manufacturing process standards. The LFXP2-40E-5FN484C ROHS3 compliance indicates adherence to current environmental standards. Substitution is valid from an electrical and functional perspective.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across 0°C to 85°C (TJ) and maintain identical supply voltage specifications of 1.14V to 1.26V.

Q: What is the significance of the packaging format difference?

A: Tray packaging (LFXP2-40E-5FN484C) is standard for active production parts and facilitates automated assembly processes. Bulk packaging (LFXP2-40E-5F484C) was used for the obsolete variant. This difference does not affect electrical performance or functionality.
