Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSB41BA3APFPG4 is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: IEEE 1394 transceiver functionality
• Electrical Specifications: Supply voltage range 1.65V ~ 3.6V
• Package Compatibility: 80-TQFP Exposed Pad / 80-HTQFP (12x12) surface mount configuration
• Base Product Designation: TSB41BA3 series
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status
• Moisture Sensitivity: MSL 3 (168 Hours)

The substitute part TSB41BA3APFP maintains identical electrical and mechanical specifications while differing only in packaging designation suffix and product availability status.

Parameter Comparison

Engineering Selection Recommendations

The TSB41BA3APFP is the direct equivalent substitute for the TSB41BA3APFPG4. Both parts share identical electrical specifications, package geometry, and regulatory compliance certifications. The primary distinction is product lifecycle status: the original part is discontinued, while the substitute remains available as a Last Time Buy offering.

Selection of TSB41BA3APFP is appropriate for applications requiring IEEE 1394 transceiver functionality within the specified voltage range and package constraints. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Are TSB41BA3APFPG4 and TSB41BA3APFP electrically identical?

A: Yes. Both parts operate at identical supply voltage ranges (1.65V ~ 3.6V), implement the same IEEE 1394 protocol, and are housed in equivalent 80-TQFP Exposed Pad packages with 80-HTQFP (12x12) physical dimensions.

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

A: The suffix designations (G4 versus no suffix) reflect packaging lot codes and product lifecycle tracking. The core silicon and electrical performance are equivalent.

Q: Can TSB41BA3APFP be used as a direct replacement in existing PCB designs?

A: Yes. Identical package geometry, pin configuration, and electrical specifications enable direct substitution without PCB redesign or layout modifications.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, MSL 3 moisture sensitivity rating, and identical ECCN and HTSUS classifications.

Q: Why is the original part discontinued?

A: Product discontinuation reflects Texas Instruments' lifecycle management. The substitute TSB41BA3APFP remains available under Last Time Buy status, providing a defined procurement window for legacy design support.
