Parameter Comparison

Engineering Selection Recommendations

The TLP785(D4-GR,F) is the designated substitute for the obsolete TLP732(D4-GR,F) based on the following engineering criteria:

• Product Lifecycle Status: The TLP732 is obsolete with no active manufacturing support. The TLP785 maintains active product status with current availability and ongoing supplier support.
• Regulatory Alignment: Both components share identical ECCN and HTSUS classifications, ensuring equivalent export control and tariff treatment.
• Compliance Certification: The TLP785 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions applicable to electronic components.
• Physical Compatibility: Identical 4-DIP package footprint and through-hole mounting configuration enable direct PCB layout compatibility without redesign.
• Electrical Performance: The TLP785 provides specified isolation voltage (5000Vrms), output voltage rating (80V), and output current capability (50mA) suitable for standard optoisolator applications.
• Inventory Availability: TLP785 stock of 947 units ensures procurement reliability compared to the limited TLP732 inventory of 876 units.

Frequently Asked Questions (FAQ)

Q: Can the TLP785(D4-GR,F) be used as a direct replacement for the TLP732(D4-GR,F)?

A: Yes. Both components share identical 4-DIP package dimensions, through-hole mounting configuration, and single-channel transistor output topology. The TLP785 provides specified electrical performance parameters (5000Vrms isolation, 80V output, 50mA output current) suitable for standard optoisolator circuit applications.

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

A: The primary difference is product lifecycle status. The TLP732 is obsolete with no active manufacturing, while the TLP785 is an active product with current supplier support. The TLP785 includes ROHS3 compliance certification and specified electrical parameters. Both maintain identical regulatory classifications (ECCN EAR99, HTSUS 8541.49.8000).

Q: Are there any packaging or mounting considerations when substituting?

A: No. Both components use identical 4-DIP (0.300", 7.62mm) through-hole packaging. No PCB layout modifications or mounting hardware changes are required for substitution.

Q: What is the moisture sensitivity level difference?

A: The TLP732 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The TLP785 lists MSL as Not Applicable, which is typical for through-hole components with minimal moisture absorption characteristics. Both are suitable for standard storage and handling conditions.

Q: How do the electrical specifications compare?

A: The TLP785 provides complete electrical specifications: 5000Vrms isolation voltage, 80V maximum output voltage, 50mA output current per channel, and -55°C to 110°C operating temperature range. The TLP732 specifications are not provided in available documentation. The TLP785 specifications represent standard performance for single-channel Toshiba optoisolators in this package class.

Q: Is the TLP785 suitable for new designs?

A: Yes. The TLP785 is an active product with current manufacturing support, ROHS3 compliance, and specified electrical performance parameters. It is appropriate for both replacement applications and new circuit designs requiring single-channel optoisolation with 5000Vrms isolation rating.
