Substitute Part Grouping Explanation

Substitution for the TLP781F(GR-TP7,F) is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor (mandatory match)
• Current Transfer Ratio: 100% - 300% @ 5mA (mandatory match)
• Maximum Output Voltage: 80V (mandatory match)
• Maximum Output Current: 50mA (mandatory match)
• Package Type: 4-SMD, Gull Wing (mandatory match)
• Input Type: DC (mandatory match)

The identified substitutes maintain identical electrical performance specifications and mechanical compatibility, differing only in product status and packaging format (tape & reel versus individual packaging).

Parameter Comparison

Engineering Selection Recommendations

Both TLP785F(GR-TP7,F) and TLP785(GR-TP6,F) are direct functional equivalents to the obsolete TLP781F(GR-TP7,F). Selection between these alternatives is based on the following criteria:

TLP785F(GR-TP7,F) is the primary substitute, maintaining identical packaging format (4-SMD, Gull Wing) and supplier device package specification. This part carries active product status and is available in standard packaging configuration.

TLP785(GR-TP6,F) is a parametric equivalent available in tape & reel packaging format with significantly higher inventory availability (13,874 pcs). This part also carries active product status and RoHS compliance certification. Selection of this variant is appropriate for high-volume applications where tape & reel format is compatible with assembly processes.

Both substitutes maintain full electrical and mechanical compatibility with the original TLP781F(GR-TP7,F) specification across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can TLP785F(GR-TP7,F) be used as a direct replacement for TLP781F(GR-TP7,F)?

A: Yes. The TLP785F(GR-TP7,F) maintains identical electrical specifications, isolation voltage, output characteristics, and 4-SMD gull wing package configuration. The primary difference is product status: TLP785F is active while TLP781F is obsolete.

Q: What is the difference between TLP785F(GR-TP7,F) and TLP785(GR-TP6,F)?

A: Both parts are parametrically equivalent with identical electrical performance. The difference is packaging format: TLP785F(GR-TP7,F) uses standard packaging while TLP785(GR-TP6,F) is supplied in tape & reel format. TLP785(GR-TP6,F) also includes RoHS compliance certification.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All three parts share identical isolation voltage (5000Vrms), output type (transistor), current transfer ratio range (100-300% @ 5mA), maximum output voltage (80V), maximum output current (50mA), and 4-SMD gull wing package configuration.

Q: Which substitute should be selected for new designs?

A: For new designs, either TLP785F(GR-TP7,F) or TLP785(GR-TP6,F) is appropriate. Selection depends on packaging requirements: use TLP785F(GR-TP7,F) for standard packaging or TLP785(GR-TP6,F) for tape & reel format applications.

Q: Is RoHS compliance a factor in part selection?

A: TLP785(GR-TP6,F) carries explicit RoHS compliance certification. If RoHS compliance is a design requirement, this part is the specified choice. Both parts maintain identical electrical performance.
