TLP719F(D4-TP,F) Equivalent & Substitute Parts

Part Overview

The TLP719F(D4-TP,F) is a photocoupler 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 alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical isolation performance, channel configuration, and output characteristics while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP719F(D4-TP,F) is determined by the following critical parameters:

Isolation Voltage: The substitute must maintain 5000Vrms isolation rating to preserve galvanic separation in the application circuit.

Channel Configuration: Single channel (1 channel) requirement must be maintained for pin-compatible replacement.

Input Type: DC input specification must be preserved for signal compatibility.

Output Current Rating: The 8mA output current per channel establishes the maximum load-driving capability that substitute parts must support.

Forward Current (If) Maximum: The 25mA maximum DC forward current on the input side defines the LED drive capability of the optoisolator.

Mounting Type and Package: Surface mount configuration with 6-pin SOIC package footprint ensures mechanical and electrical compatibility on printed circuit boards.

Compliance and Status: Active product status with current manufacturing availability and RoHS3 compliance ensure long-term supply chain viability and regulatory conformance.

The TLP2719(D4-TP4,E) qualifies as a substitute based on matching isolation voltage, channel count, input type, output current rating, forward current specification, surface mount configuration, and active product status with enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TLP2719(D4-TP4,E) is the qualified substitute for the obsolete TLP719F(D4-TP,F) based on the following engineering criteria:

Electrical Equivalence: Both devices maintain identical isolation voltage (5000Vrms), single channel configuration, DC input type, 8mA output current per channel, 25mA maximum forward current, and 800ns propagation delay specifications. These parameters ensure functional compatibility in isolation and signal transmission applications.

Product Status and Supply Chain: The TLP2719(D4-TP4,E) holds active product status with 988 units in current inventory, providing immediate availability and long-term manufacturing support. The obsolete status of the TLP719F(D4-TP,F) eliminates future procurement viability.

Compliance and Certifications: The TLP2719(D4-TP4,E) carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both devices share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Package Compatibility: Both devices utilize 6-SOIC surface mount packages with identical pin counts. The TLP2719(D4-TP4,E) package width (7.50mm) is slightly larger than the TLP719F(D4-TP,F) (6.80mm), but both conform to standard 6-SOIC footprint specifications and are compatible with existing PCB layouts designed for 6-pin SOIC components.

Operating Temperature Consideration: The TLP2719(D4-TP4,E) operating temperature range (-40°C ~ 100°C) is narrower than the TLP719F(D4-TP,F) (-55°C ~ 100°C) at the lower temperature limit. Applications requiring operation below -40°C must evaluate alternative substitutes or confirm that the narrower range meets system requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLP2719(D4-TP4,E) directly replace the TLP719F(D4-TP,F) in existing designs?

A: The TLP2719(D4-TP4,E) provides electrical and functional equivalence for the TLP719F(D4-TP,F) across all critical isolation, channel, input, output, and timing parameters. Both devices use 6-SOIC surface mount packages with identical pin counts. PCB layout compatibility is maintained. However, the operating temperature range of the substitute is narrower at the lower limit (-40°C versus -55°C), which must be evaluated against application requirements.

Q: What are the key differences between these two optoisolators?

A: The primary differences are product status (TLP719F is obsolete; TLP2719 is active), operating temperature range (TLP719F: -55°C to 100°C; TLP2719: -40°C to 100°C), package width (TLP719F: 6.80mm; TLP2719: 7.50mm), and compliance certifications (TLP2719 carries RoHS3 and REACH documentation). Electrical performance parameters including isolation voltage, output current, forward current, and propagation delay are identical.

Q: Are there pin-to-pin compatibility concerns between these parts?

A: Both devices use 6-pin SOIC packages with identical pin counts and standard SOIC pin spacing. Pin-to-pin compatibility is maintained for direct PCB replacement. The slightly larger package width of the TLP2719(D4-TP4,E) does not affect pin alignment or electrical connections on standard 6-SOIC footprints.

Q: What output type difference exists between the TLP719F and TLP2719?

A: The TLP719F(D4-TP,F) features transistor output, while the TLP2719(D4-TP4,E) features open collector output. Both output types provide 8mA maximum output current per channel and are compatible with standard logic and analog circuits. Open collector output offers flexibility for pull-up resistor selection and multi-device wired-OR configurations.

Q: Does the TLP2719(D4-TP4,E) support the same isolation voltage as the TLP719F(D4-TP,F)?

A: Yes. Both devices maintain 5000Vrms isolation voltage rating, ensuring equivalent galvanic separation between input and output circuits.

Q: What is the significance of the narrower operating temperature range in the TLP2719(D4-TP4,E)?

A: The TLP2719(D4-TP4,E) operates from -40°C to 100°C, compared to the TLP719F(D4-TP,F) range of -55°C to 100°C. Applications requiring operation below -40°C must confirm that the substitute's temperature range meets system specifications. Most commercial and industrial applications operate within the -40°C to 100°C range.

Q: Is the TLP2719(D4-TP4,E) available in the same packaging format?

A: Both devices are supplied in 6-SOIC surface mount packages. The TLP2719(D4-TP4,E) is available in Tape & Reel (TR) packaging format, which is standard for high-volume production. The TLP719F(D4-TP,F) packaging format is not specified in the available data.

Q: What compliance certifications does the TLP2719(D4-TP4,E) carry?

A: The TLP2719(D4-TP4,E) is RoHS3 compliant and REACH unaffected. Both devices share EAR99 export control classification and 8541.49.8000 HTSUS tariff code.
