Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP719(D4-TP,F) is determined by the following critical parameters that must remain constant or improve:

Mandatory Matching Parameters:

• Voltage - Isolation: 5000Vrms (galvanic isolation requirement)
• Number of Channels: 1 (single channel configuration)
• Current - Output / Channel: 8mA (output current capability)
• Current - DC Forward (If) (Max): 25mA (input current specification)
• Mounting Type: Surface Mount (PCB assembly compatibility)

Performance Parameters:

• Turn On / Turn Off Time: 800ns maximum (switching speed requirement)
• Voltage - Forward (Vf): 1.65V typical (input LED forward voltage)

The TLP2719(D4-TP,E) qualifies as a direct substitute because it maintains all mandatory parameters while offering enhanced specifications including active product status, improved common mode transient immunity (10kV/µs), and extended voltage supply range (4.5V ~ 20V). The output type transitions from transistor to open collector, which represents a functional enhancement for logic-level applications while maintaining electrical compatibility in standard isolation circuits.

Engineering Selection Recommendations

The TLP2719(D4-TP,E) is the manufacturer-recommended substitute for the obsolete TLP719(D4-TP,F). Selection of this substitute is based on the following engineering criteria:

Product Status & Availability: The TLP719(D4-TP,F) is classified as obsolete, making long-term supply and support unavailable. The TLP2719(D4-TP,E) maintains active product status with confirmed inventory availability (1555 pcs in stock), ensuring supply chain continuity for new designs and production requirements.

Electrical Compatibility: The substitute maintains all critical electrical parameters including 5000Vrms isolation voltage, 8mA output current, 25mA maximum input current, and 800ns switching times. These specifications ensure functional equivalence in isolation and switching applications.

Compliance & Certification: Both components carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, confirming regulatory and trade compliance equivalence. The TLP2719(D4-TP,E) includes Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited shelf life under standard storage conditions.

Output Configuration Enhancement: The transition from transistor output to open collector output represents a functional improvement for logic-level signal processing, providing superior noise immunity and compatibility with standard digital logic circuits while maintaining electrical isolation performance.

Temperature Operating Range Consideration: The substitute operates across -40°C to 100°C compared to the original -55°C to 100°C range. Applications requiring operation below -40°C require design review and alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the TLP2719(D4-TP,E) be used as a direct replacement for the TLP719(D4-TP,F) in existing designs?

A: Yes, the TLP2719(D4-TP,E) is the manufacturer-recommended substitute and maintains all critical electrical parameters including isolation voltage, output current, input current, and switching speed. The open collector output configuration is functionally compatible with standard isolation circuit topologies. PCB layout modifications may be required due to minor package width variation (6.80mm vs 7.50mm).

Q: What is the difference between transistor output and open collector output?

A: The TLP719(D4-TP,F) features a transistor output that provides direct switching capability. The TLP2719(D4-TP,E) features an open collector output that requires an external pull-up resistor for logic-level signal generation. Open collector configuration provides improved noise immunity and compatibility with standard digital logic circuits.

Q: Are there package compatibility issues between these components?

A: Both components use 6-SOIC surface mount packages. The TLP719(D4-TP,F) has a package width of 0.268" (6.80mm), while the TLP2719(D4-TP,E) has a width of 0.295" (7.50mm). This 0.027" (0.70mm) difference falls within standard 6-SOIC tolerance specifications and does not affect PCB footprint compatibility for most applications. Verify specific PCB layout constraints for high-density designs.

Q: What is the operating temperature range difference, and does it affect substitution?

A: The TLP719(D4-TP,F) operates from -55°C to 100°C, while the TLP2719(D4-TP,E) operates from -40°C to 100°C. The substitute has a narrower low-temperature range. Applications requiring operation below -40°C must retain the original component or select an alternative optoisolator with extended low-temperature specifications.

Q: Are the input LED forward voltage specifications compatible?

A: Yes. The TLP719(D4-TP,F) specifies 1.65V typical forward voltage, while the TLP2719(D4-TP,E) specifies 1.6V typical. This 0.05V difference is negligible and falls within standard component tolerance. Input drive circuits designed for the original component operate within specification for the substitute.

Q: What is the significance of the Common Mode Transient Immunity (CMTI) specification in the substitute?

A: The TLP2719(D4-TP,E) specifies 10kV/µs CMTI, which is not listed for the original TLP719(D4-TP,F). This parameter indicates the rate of change of common mode voltage that the optoisolator can withstand without false triggering. The substitute's specified CMTI provides enhanced noise immunity in high-speed switching applications and represents a performance improvement over the original component.

Q: Is the Moisture Sensitivity Level (MSL) rating important for component handling?

A: Yes. The TLP2719(D4-TP,E) carries MSL 1 rating, indicating unlimited shelf life under standard storage conditions (less than 30°C and 85% relative humidity). This eliminates moisture bake-out requirements and simplifies inventory management compared to components with higher MSL ratings.

Q: What certifications and compliance standards apply to both components?

A: Both the TLP719(D4-TP,F) and TLP2719(D4-TP,E) carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. These designations confirm equivalent regulatory and trade compliance status for export control and tariff purposes.
