TPC816S1D RAG Equivalent & Substitute Parts

Part Overview

The TPC816S1D RAG is an optoisolator with transistor output manufactured by Taiwan Semiconductor Corporation. This component provides 5000Vrms isolation with a single channel in a 4-SOP surface mount package. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The TPC816S1D RAG operates across a temperature range of -30°C to 100°C and delivers a current transfer ratio between 300% and 600% at 5mA input current.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPC816S1D RAG is determined by strict equivalence across the following critical parameters:

Isolation Voltage: All substitute parts must maintain 5000Vrms isolation rating.

Channel Configuration: Single channel requirement must be preserved.

Current Transfer Ratio: Minimum 300% and maximum 600% at 5mA input current.

Output Characteristics: Transistor output type with maximum output voltage of 70V and maximum output current of 50mA per channel.

Saturation Voltage: Vce saturation maximum of 200mV.

Switching Performance: Rise and fall times of 4µs and 3µs respectively.

Package Compatibility: 4-SMD, Gull Wing surface mount configuration.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status.

The substitute parts listed below meet all these electrical and mechanical parameters, enabling direct functional replacement in applications currently using the TPC816S1D RAG.

Engineering Selection Recommendations

FOD817DSD (onsemi): This substitute part is manufactured by onsemi and carries active product status, ensuring long-term availability and support. The FOD817DSD meets all electrical parameters of the TPC816S1D RAG and provides an extended operating temperature range of -55°C to 110°C, offering broader thermal performance. This part is suitable for applications requiring enhanced temperature margin beyond the original specification.

HCPL-817-50DE (Broadcom Limited): This parametric equivalent is manufactured by Broadcom Limited with active product status. The HCPL-817-50DE maintains identical electrical specifications and operating temperature range to the TPC816S1D RAG. This part is available in Cut Tape and Digi-Reel packaging, matching the original packaging format.

HCPL-817-56DE (Broadcom Limited): Also manufactured by Broadcom Limited with active product status, the HCPL-817-56DE provides full electrical equivalence to the TPC816S1D RAG. This variant is supplied in Tape & Reel packaging format and maintains the same operating temperature range and electrical characteristics.

All three substitute parts comply with ROHS3 regulations and carry REACH unaffected status, meeting current environmental and regulatory requirements. Selection between these options depends on packaging requirements, supplier availability, and thermal performance needs for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the FOD817DSD replace the TPC816S1D RAG in all applications?

A: The FOD817DSD meets all critical electrical parameters of the TPC816S1D RAG, including isolation voltage, current transfer ratio, output voltage and current ratings, and switching characteristics. The extended operating temperature range of -55°C to 110°C provides additional thermal margin. Substitution is valid for applications operating within the original -30°C to 100°C range. Physical package compatibility is confirmed as both use 4-SMD, Gull Wing surface mount configuration.

Q: What is the difference between HCPL-817-50DE and HCPL-817-56DE?

A: The HCPL-817-50DE and HCPL-817-56DE are electrically identical and meet all parameters of the TPC816S1D RAG. The primary difference is packaging format: HCPL-817-50DE is supplied in Cut Tape and Digi-Reel format, while HCPL-817-56DE is supplied in Tape & Reel format. Selection depends on manufacturing process requirements and supplier inventory.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all three substitute parts (FOD817DSD, HCPL-817-50DE, and HCPL-817-56DE) are ROHS3 compliant and carry REACH unaffected status, meeting current environmental regulations.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: 5000Vrms isolation voltage, single channel configuration, 300% to 600% current transfer ratio at 5mA, transistor output type, 70V maximum output voltage, 50mA maximum output current, 200mV maximum Vce saturation, 4µs and 3µs rise and fall times, and 4-SMD Gull Wing surface mount package.

Q: Can the FOD817DSD be used in applications with temperature extremes beyond -30°C to 100°C?

A: The FOD817DSD operates across -55°C to 110°C, extending the lower and upper temperature limits compared to the TPC816S1D RAG. Applications requiring operation below -30°C or above 100°C can utilize the FOD817DSD within its specified temperature range.

Q: Are there any differences in moisture sensitivity between the main part and substitutes?

A: No. The TPC816S1D RAG and all three substitute parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
