TLP719F(AD-TP,F) Equivalent & Substitute Parts

Part Overview

The TLP719F(AD-TP,F) is an optoisolator with transistor output manufactured by Toshiba Semiconductor and Storage. This component provides galvanic isolation up to 5000Vrms with a single channel configuration in a 6-SDIP gull wing surface mount package. The device is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. The TLP2719(TP4,E) serves as the primary substitute, offering enhanced specifications while maintaining core isolation and channel characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP719F(AD-TP,F) is determined by the following critical parameters that must remain constant or be exceeded:

Mandatory Matching Parameters:

• Voltage - Isolation: 5000Vrms (minimum requirement)
• Number of Channels: 1 channel
• Current - Output / Channel: 8mA (minimum capability)
• Current - DC Forward (If) (Max): 25mA (minimum capability)
• Mounting Type: Surface Mount

Performance Parameters:

• Turn On / Turn Off Time: 800ns maximum (switching speed requirement)
• Voltage - Forward (Vf): 1.65V typical (input LED forward voltage)
• Operating Temperature Range: Must encompass or exceed -55°C ~ 100°C

The TLP2719(TP4,E) qualifies as a substitute by meeting or exceeding all mandatory parameters while offering enhanced specifications including active product status, higher common mode transient immunity (10kV/µs), and extended supply voltage range (4.5V ~ 20V).

Parameter Comparison

Engineering Selection Recommendations

The TLP2719(TP4,E) is the appropriate substitute for the obsolete TLP719F(AD-TP,F) based on the following engineering criteria:

Product Status and Availability: The TLP2719(TP4,E) maintains active manufacturing status with 4334 units in stock, compared to the obsolete status of the TLP719F(AD-TP,F). This ensures long-term supply chain continuity and component availability for production and field replacement requirements.

Compliance and Certifications: The TLP2719(TP4,E) is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components. The Moisture Sensitivity Level rating of 1 (Unlimited) provides maximum flexibility for storage and handling conditions.

Electrical Parameter Equivalence: All critical electrical parameters match or exceed the original specification. The isolation voltage (5000Vrms), output current capability (8mA), forward current rating (25mA), and switching time characteristics (800ns) are identical. The operating temperature range of the TLP2719(TP4,E) (-40°C ~ 100°C) covers the upper portion of the original range; applications requiring operation below -40°C require design review.

Enhanced Specifications: The TLP2719(TP4,E) provides additional performance benefits including common mode transient immunity of 10kV/µs and a wider supply voltage range (4.5V ~ 20V), offering improved noise immunity and design flexibility.

Frequently Asked Questions (FAQ)

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

A: The TLP2719(TP4,E) meets all mandatory electrical parameters for substitution. However, the operating temperature minimum differs: TLP719F operates to -55°C while TLP2719 operates to -40°C. Applications requiring operation below -40°C require design modification or alternative component selection. Package dimensions differ slightly (6-SOIC 0.295" vs. 6-SDIP 0.268"), requiring PCB layout verification.

Q: What are the key differences between the TLP719F(AD-TP,F) and TLP2719(TP4,E)?

A: The primary differences are: (1) Output type changes from transistor to open collector logic output; (2) TLP2719 includes common mode transient immunity specification (10kV/µs); (3) TLP2719 specifies data rate capability (1MBd); (4) TLP2719 includes supply voltage range specification (4.5V ~ 20V); (5) TLP2719 is active product with current manufacturing and compliance certifications.

Q: Are there package compatibility considerations?

A: Both components use 6-pin surface mount packages but with different dimensions. TLP719F uses 6-SDIP gull wing (0.268" width, 6.80mm), while TLP2719 uses 6-SOIC (0.295" width, 7.50mm). PCB footprint verification is required before substitution. Pin configuration compatibility must be confirmed for the specific application circuit.

Q: What is the significance of the TLP2719 being an "open collector" output versus the TLP719F "transistor" output?

A: Both configurations provide transistor-based switching. The TLP2719 open collector output is optimized for logic-level applications with specified pull-up voltage range (4.5V ~ 20V), while the TLP719F transistor output operates with maximum output voltage of 20V. The TLP2719 is specifically designed for high-speed logic applications with 1MBd data rate capability.

Q: Is the TLP2719(TP4,E) suitable for applications requiring -55°C operation?

A: No. The TLP2719(TP4,E) minimum operating temperature is -40°C. Applications requiring operation at -55°C must either identify alternative components with extended low-temperature ratings or modify system design to operate within the -40°C ~ 100°C range.

Q: What compliance advantages does the TLP2719(TP4,E) provide?

A: The TLP2719(TP4,E) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The Moisture Sensitivity Level of 1 (Unlimited) eliminates moisture-related handling restrictions. The TLP719F(AD-TP,F) compliance status is not specified, making the TLP2719 the preferred choice for new designs and regulated applications.
