TPC816B C9G Equivalent & Substitute Parts

Part Overview

The TPC816B C9G is a 5000Vrms optoisolator with transistor output manufactured by Taiwan Semiconductor Corporation. This component features a single channel, 4-DIP through-hole package, and is classified as obsolete. The TPC816B C9G serves applications requiring galvanic isolation with DC input and transistor output configuration. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitute parts for the TPC816B C9G are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio (Min): 130% @ 5mA
• Current Transfer Ratio (Max): 260% @ 5mA
• Voltage - Output (Max): 70V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Rise / Fall Time (Typ): 4µs, 3µs
• Package / Case: 4-DIP
• Mounting Type: Through Hole
• Input Type: DC

The substitute parts FOD817B, HCPL-817-W0BE, and HCPL-817-W6BE meet all mandatory electrical and mechanical parameters. These parts are sourced from active manufacturers (onsemi and Broadcom Limited) and maintain full compliance with RoHS3 and REACH regulations.

Parameter Comparison

Engineering Selection Recommendations

FOD817B (onsemi): This substitute is an active product with extended operating temperature range (-55°C ~ 110°C), providing broader thermal performance than the TPC816B C9G. The FOD817B features a 4-DIP package with 0.300" (7.62mm) body height, which differs from the original 0.400" (10.16mm) dimension. This dimensional difference requires PCB layout verification for through-hole mounting compatibility. The FOD817B maintains full RoHS3 compliance and REACH unaffected status.

HCPL-817-W0BE (Broadcom Limited): This substitute maintains identical electrical specifications and operating temperature range (-30°C ~ 100°C) to the TPC816B C9G. The HCPL-817-W0BE uses the same 4-DIP package dimension (0.400", 10.16mm), ensuring direct mechanical compatibility. This part is an active product with full RoHS3 compliance and REACH unaffected status.

HCPL-817-W6BE (Broadcom Limited): This substitute is functionally equivalent to the HCPL-817-W0BE with identical electrical specifications, operating temperature range, and package dimensions (0.400", 10.16mm). The HCPL-817-W6BE is an active product with full RoHS3 compliance and REACH unaffected status.

All three substitute parts satisfy the mandatory electrical and regulatory requirements for direct replacement of the obsolete TPC816B C9G. Selection between FOD817B and the Broadcom HCPL-817 variants depends on package dimension requirements and thermal operating range specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can FOD817B be used as a direct replacement for TPC816B C9G in existing PCB designs?

A: FOD817B meets all electrical specifications but has a different 4-DIP package height (0.300" versus 0.400"). Through-hole mounting compatibility must be verified against PCB hole spacing and component clearance requirements before implementation.

Q: What is the primary difference between HCPL-817-W0BE and HCPL-817-W6BE?

A: Both parts are electrically and mechanically identical. They share the same electrical specifications, operating temperature range (-30°C ~ 100°C), and 4-DIP package dimensions (0.400", 10.16mm). Selection between these variants depends on supplier availability and packaging format (both supplied in tube packaging).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. FOD817B, HCPL-817-W0BE, and HCPL-817-W6BE are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does FOD817B have superior performance due to its extended operating temperature range?

A: FOD817B operates from -55°C to 110°C, compared to the TPC816B C9G range of -30°C to 100°C. This extended range is beneficial only for applications requiring operation outside the original temperature specification. All other electrical parameters are identical.

Q: Which substitute part provides the closest mechanical compatibility with TPC816B C9G?

A: HCPL-817-W0BE and HCPL-817-W6BE both use the identical 4-DIP package dimension (0.400", 10.16mm) as the TPC816B C9G, ensuring direct mechanical compatibility without PCB modification.

Q: Are these substitute parts available in high volume?

A: FOD817B (9674 pcs), HCPL-817-W0BE (916 pcs), and HCPL-817-W6BE (3022 pcs) are all available in stock as new original components from their respective manufacturers.
