Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP190B(COSTPLUC,F is determined by the following critical parameters:

Functional Equivalence Criteria:

• Single-channel photovoltaic optoisolator architecture
• Photovoltaic output type for isolated power generation
• Surface mount technology compatibility
• DC input type

Electrical Compatibility Parameters:

• Isolation voltage rating (minimum 2500Vrms required)
• Output voltage capability (maximum 8V or greater)
• Output current per channel (minimum 12µA or greater)
• Operating temperature range encompassing -40°C to 85°C

Physical Compatibility Parameters:

• Surface mount package configuration
• 4-lead device structure
• Pin-compatible or functionally equivalent pinout

The TLP3905(TPL,E meets these substitution criteria through enhanced electrical specifications while maintaining functional compatibility with the obsolete TLP190B(COSTPLUC,F.

Parameter Comparison

Engineering Selection Recommendations

The TLP3905(TPL,E serves as the active equivalent for the obsolete TLP190B(COSTPLUC,F based on the following engineering factors:

Product Status Alignment: The TLP3905(TPL,E maintains active production status with Toshiba Semiconductor and Storage, ensuring long-term availability and supply chain continuity compared to the obsolete TLP190B(COSTPLUC,F.

Electrical Performance: The TLP3905(TPL,E provides enhanced isolation voltage (3750Vrms versus 2500Vrms), increased output current capability (30µA typical versus 12µA), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). These parameters represent improvements over the original specification without introducing incompatibility.

Compliance and Certifications: The TLP3905(TPL,E is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both devices share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Package Consideration: The TLP3905(TPL,E utilizes a 6-SOIC package format compared to the 6-SMD gull wing package of the TLP190B(COSTPLUC,F. PCB layout modification is required for physical integration.

Frequently Asked Questions (FAQ)

Q: Can the TLP3905(TPL,E directly replace the TLP190B(COSTPLUC,F without circuit modification?

A: Electrical substitution is valid based on isolation voltage, output current, and temperature range parameters. However, physical substitution requires PCB layout changes due to different package formats (6-SOIC versus 6-SMD gull wing).

Q: What are the key electrical differences between these components?

A: The TLP3905(TPL,E provides higher isolation voltage (3750Vrms), greater output current (30µA typical), and wider operating temperature range (-40°C to 125°C). Output voltage is slightly lower (7V maximum versus 8V maximum). These differences favor the substitute in most isolation and temperature-critical applications.

Q: Is the TLP3905(TPL,E suitable for applications originally designed for the TLP190B(COSTPLUC,F?

A: Yes, provided the application can accommodate the different package footprint. The electrical parameters of the TLP3905(TPL,E meet or exceed the requirements of the original design.

Q: What is the significance of the product status difference?

A: The TLP190B(COSTPLUC,F is obsolete and no longer manufactured. The TLP3905(TPL,E is in active production, ensuring availability for new designs and ongoing production support.

Q: Are there packaging considerations for this substitution?

A: Yes. The TLP190B(COSTPLUC,F uses a 6-SMD (4 Leads) gull wing package, while the TLP3905(TPL,E uses a 6-SOIC package. PCB redesign is necessary to accommodate the different pin spacing and lead configuration.

Q: Do both components share the same compliance certifications?

A: Both devices are classified under ECCN EAR99 and HTSUS 8541.49.8000. The TLP3905(TPL,E additionally carries RoHS3 compliance and REACH unaffected status, meeting current regulatory standards.
