Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP719F(TP,F) is based on the following critical parameters that must align between the main part and substitute candidates:

Isolation Voltage: 5000Vrms isolation rating is the primary electrical requirement for galvanic isolation performance.

Number of Channels: Single-channel configuration must be maintained for circuit compatibility.

Input Type: DC input specification must be preserved.

Current - Output / Channel: 8mA output current capability must be supported.

Voltage - Forward (Vf): Input diode forward voltage characteristics must be compatible with existing drive circuits.

Current - DC Forward (If) (Max): Maximum input current rating of 25mA must be met or exceeded.

Mounting Type: Surface mount requirement must be maintained for PCB assembly compatibility.

Operating Temperature Range: The substitute must support the required temperature envelope or a compatible subset thereof.

The TLP2719(TP4,E) qualifies as a substitute based on these parameters. While the output type differs (open collector versus transistor with base), both configurations provide isolated switching capability within the specified electrical constraints.

Parameter Comparison

Engineering Selection Recommendations

The TLP2719(TP4,E) is available as an active product with current manufacturing support, addressing the obsolescence status of the TLP719F(TP,F). Both components share identical isolation voltage (5000Vrms), single-channel configuration, input type (DC), output current capability (8mA), and forward voltage characteristics within acceptable tolerance.

The TLP2719(TP4,E) carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The operating temperature range of the substitute (-40°C ~ 100°C) covers the upper portion of the original specification (-55°C ~ 100°C); applications requiring operation below -40°C require verification against specific system requirements.

Package dimensions differ slightly between the two components (6.80mm versus 7.50mm width). PCB layout verification is necessary to confirm physical fit within existing footprints.

The primary design consideration is the output configuration change from transistor with base to open collector. This difference affects circuit interface requirements and must be evaluated against the specific application's output stage design.

Frequently Asked Questions (FAQ)

Q: Can the TLP2719(TP4,E) directly replace the TLP719F(TP,F) in existing designs?

A: Direct replacement requires circuit-level evaluation. Both components provide 5000Vrms isolation with 8mA output current and compatible input characteristics. The output stage differs (transistor with base versus open collector), necessitating verification that the receiving circuit can accommodate the open collector configuration.

Q: What is the impact of the package dimension difference?

A: The TLP2719(TP4,E) has a 6-SOIC package width of 7.50mm compared to 6.80mm for the TLP719F(TP,F). Both are 6-pin SOIC packages. PCB footprint compatibility must be confirmed; the slightly larger width may require layout adjustment depending on component spacing constraints.

Q: Does the TLP2719(TP4,E) support the full temperature range of the original part?

A: The TLP2719(TP4,E) operates from -40°C to 100°C, while the TLP719F(TP,F) operates from -55°C to 100°C. Applications requiring operation below -40°C must confirm compatibility with system temperature requirements.

Q: Are there compliance differences between these components?

A: The TLP2719(TP4,E) is ROHS3 compliant and REACH unaffected. The TLP719F(TP,F) compliance status is not specified in available documentation. Both components carry EAR99 ECCN classification and identical HTSUS codes.

Q: What is the significance of the output type difference?

A: The TLP719F(TP,F) provides a transistor output with accessible base connection, allowing direct base current control. The TLP2719(TP4,E) provides open collector output, requiring external pull-up resistor configuration. Circuit design must accommodate this interface difference.

Q: Is the TLP2719(TP4,E) the only available substitute?

A: Based on the provided substitute list, the TLP2719(TP4,E) is the manufacturer-recommended equivalent. Other optoisolators with 5000Vrms isolation and single-channel configuration may exist in the market; component selection should prioritize parts meeting all specified electrical and mechanical parameters.
