TLP715(TP,F) Equivalent & Substitute Parts

Part Overview

The TLP715(TP,F) is a logic output optoisolator manufactured by Toshiba Semiconductor and Storage, designed for high-speed digital isolation applications. This device features a single-channel push-pull totem pole output configuration with 5000Vrms isolation capability and 10kV/µs common mode transient immunity. The component operates at data rates up to 5Mbps and is housed in a 6-SDIP gull wing surface mount package.

The TLP715(TP,F) is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP715(TP,F) is determined by the following critical parameters that must be maintained or exceeded:

Mandatory Matching Parameters:

• Number of Channels: 1
• Voltage - Isolation: 5000Vrms (minimum)
• Input Type: DC
• Output Type: Push-Pull, Totem Pole
• Mounting Type: Surface Mount
• Package Category: 6-pin SOIC variant

Parameters Allowing Improvement:

• Common Mode Transient Immunity: May be equal or higher
• Current - Output / Channel: May be equal or higher
• Propagation Delay: May be equal or lower (faster operation)
• Voltage - Supply Range: May be equal or wider
• Operating Temperature Range: May be equal or wider

The TLP2745(TP,E) qualifies as a direct substitute because it maintains all mandatory parameters while providing enhanced performance characteristics in CMTI, output current, propagation delay, and supply voltage range. Both devices are manufactured by Toshiba Semiconductor and Storage and share identical isolation voltage and channel configuration.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TLP715(TP,F) is classified as obsolete, while the TLP2745(TP,E) maintains active product status. Active status ensures continued manufacturing support, availability, and compliance with current industry standards.

Compliance and Certification: The TLP2745(TP,E) is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components. Both devices carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Performance Enhancement: The TLP2745(TP,E) provides measurable improvements across multiple performance parameters: 3x higher common mode transient immunity (30kV/µs vs. 10kV/µs), 2x higher output current capability (50mA vs. 25mA), and significantly faster propagation delay (120ns vs. 250ns). These enhancements do not compromise compatibility with applications designed for the TLP715(TP,F).

Package Consideration: Both devices use 6-SOIC surface mount packages. The TLP2745(TP,E) has a slightly wider body (7.50mm vs. 6.80mm). PCB layout verification is required to confirm physical fit within existing designs, though both packages are standard 6-pin SOIC variants.

Frequently Asked Questions (FAQ)

Q: Can the TLP2745(TP,E) directly replace the TLP715(TP,F) in existing designs?

A: The TLP2745(TP,E) is functionally compatible with the TLP715(TP,F) for all critical isolation and output characteristics. Both devices provide identical 5000Vrms isolation, single-channel DC input, and push-pull totem pole output configuration. Physical PCB layout must be verified due to the 0.70mm difference in package body width (6.80mm vs. 7.50mm).

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

A: The primary differences are: (1) Common Mode Transient Immunity is 30kV/µs for the TLP2745(TP,E) versus 10kV/µs for the TLP715(TP,F); (2) Output current is 50mA versus 25mA; (3) Propagation delay is 120ns versus 250ns; (4) Supply voltage range extends to 30V versus 20V; (5) Operating temperature range extends to 110°C versus 100°C; (6) Product status is active versus obsolete.

Q: Are there any electrical parameter limitations when substituting the TLP2745(TP,E)?

A: No electrical limitations exist. The TLP2745(TP,E) meets or exceeds all electrical specifications of the TLP715(TP,F). The substitute device provides enhanced performance without reducing any capability required by the original design.

Q: What is the significance of the package width difference?

A: The TLP2745(TP,E) body width is 7.50mm compared to 6.80mm for the TLP715(TP,F). This 0.70mm difference may affect PCB layout in space-constrained applications. Pin spacing and lead configuration remain identical for both 6-SOIC packages. Physical verification of available PCB space is necessary before component substitution.

Q: Does the TLP2745(TP,E) require different circuit design considerations?

A: No circuit design changes are required. The TLP2745(TP,E) operates within the same voltage supply range (4.5V minimum) and maintains identical isolation voltage and output type. The enhanced performance characteristics (higher CMTI, faster propagation delay, higher output current) provide design margin without requiring modification to existing circuits.

Q: What is the inventory status for these components?

A: The TLP715(TP,F) has 10,200 pieces in stock as new original inventory. The TLP2745(TP,E) has 2,100 pieces in stock as new original inventory in cut tape and digi-reel packaging formats.
