Substitute Part Grouping Explanation

Substitute parts for the TL28L92IFR are identified based on the following critical parameters that must remain equivalent:

• Manufacturer: Texas Instruments (same design lineage)
• Number of Channels: 2 DUART channels
• FIFO Depth: 16 Byte
• Data Rate: 1Mbps maximum
• Supply Voltage Range: 3.3V and 5V operation
• Package Type: 44-QFP (10x10) Surface Mount
• Functional Features: Configurable GPIO, Internal Oscillator, Timer/Counter, Modem Control, False Start Bit Detection
• Compliance: ROHS3 Compliant, Moisture Sensitivity Level 3
• Product Status: Active

The TL28L92FR qualifies as a parametric equivalent based on identical electrical specifications, package configuration, and feature set across all critical selection criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the TL28L92IFR and TL28L92FR maintain Active product status from Texas Instruments, ensuring continued manufacturing support and availability. Both parts carry identical ROHS3 compliance certification and REACH unaffected status, meeting environmental and regulatory requirements. The electrical specifications, package configuration, and functional feature set are equivalent across both parts, supporting direct substitution in applications requiring dual UART channels with 16-byte FIFO, modem control, and false start bit detection at 1Mbps data rates across 3.3V and 5V supply domains. Selection between these parts may be based on inventory availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the TL28L92FR replace the TL28L92IFR in existing designs?
