Substitute Part Grouping Explanation

Substitution of the TLP9118(OGI-TL,F) is based on the following critical parameters that define functional equivalence within the optoisolator category:

Primary Substitution Criteria:

• Isolation Voltage Rating: Minimum 3750Vrms isolation capability
• Common Mode Transient Immunity (CMTI): Minimum 15kV/µs performance
• Channel Configuration: Single channel (1 channel) logic output topology
• Output Type: Open collector configuration
• Data Rate: 10MBd minimum throughput
• Supply Voltage Compatibility: 4.5V to 5.5V operating range
• Package Compatibility: Surface mount configuration with appropriate lead count
• Regulatory Compliance: EAR99 classification and automotive-grade qualification (AEC-Q101)

The TLX9378(TPL,F) meets all substitution criteria as an active, production-qualified alternative with equivalent electrical performance and enhanced availability.

Engineering Selection Recommendations

Primary Recommendation: TLX9378(TPL,F)

The TLX9378(TPL,F) is the designated substitute for the obsolete TLP9118(OGI-TL,F). Selection of this alternative is supported by the following engineering factors:

1. Product Status Transition: The TLX9378(TPL,F) maintains active production status with full manufacturing support, addressing the obsolescence of the original component.

2. Regulatory and Compliance Alignment: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, ensuring consistent export control and tariff treatment.

3. Automotive-Grade Qualification: The TLX9378(TPL,F) carries AEC-Q101 automotive qualification, providing enhanced reliability assurance for mission-critical applications.

4. Functional Equivalence: The substitute maintains the single-channel logic output optoisolator topology with open collector configuration, supporting direct functional replacement in circuit designs.

5. Supply Chain Continuity: Current inventory of 3747 units ensures procurement availability and reduces lead time risk compared to obsolete stock depletion.

6. Packaging Compatibility: Surface mount 6-SOIC configuration with 5 leads supports standard PCB assembly processes without requiring design modifications.
