Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-817-00LE is determined by strict equivalence in the following critical parameters:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor (mandatory match)
• Voltage - Output (Max): 70V (mandatory match)
• Current - Output / Channel: 50mA (mandatory match)
• Package / Case: 4-DIP (0.300", 7.62mm) (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Input Type: DC (mandatory match)

Substitute parts must maintain these electrical and mechanical specifications. Variations in Current Transfer Ratio, Rise/Fall Time, Vce Saturation, forward voltage, and operating temperature range are permitted within the scope of component selection, provided all mandatory parameters remain constant.

The HCPL-817-06LE (Broadcom Limited) is a parametric equivalent within the same manufacturer family. The TCET1103, TCET1106, TCET1107, TCET1108, and TCET1109 (Vishay Semiconductor Opto Division) are manufacturer-recommended alternatives that satisfy all mandatory electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the HCPL-817-00LE. The HCPL-817-06LE provides direct parametric equivalence within the Broadcom product family and is suitable for direct replacement in existing designs.

The Vishay TCET series (TCET1103, TCET1106, TCET1107, TCET1108, TCET1109) are manufacturer-recommended alternatives that satisfy all mandatory electrical and mechanical specifications. These parts differ in Current Transfer Ratio performance bands, allowing selection based on specific circuit requirements. The TCET1108 and TCET1109 offer higher current transfer ratios (130–400%), while TCET1103 and TCET1107 provide moderate ratios (80–200%). TCET1106 spans 100–300%.

All substitute parts support the same 4-DIP through-hole package, 5000Vrms isolation voltage, 70V maximum output voltage, and 50mA output current. Operating temperature ranges extend to -40°C for Vishay alternatives, providing broader environmental coverage compared to the -30°C lower limit of the Broadcom HCPL-817-00LE.

Frequently Asked Questions (FAQ)

Q: Can TCET1103, TCET1106, TCET1107, TCET1108, or TCET1109 be used as direct replacements for HCPL-817-00LE?

A: Yes. All Vishay TCET parts maintain identical isolation voltage (5000Vrms), output type (transistor), package (4-DIP through-hole), maximum output voltage (70V), and output current (50mA). These are the mandatory parameters for substitution. Differences in Current Transfer Ratio and Vce Saturation do not prevent functional replacement in applications where the circuit design accommodates the specified performance ranges.

Q: What is the difference between HCPL-817-06LE and HCPL-817-00LE?

A: The HCPL-817-06LE is a parametric equivalent manufactured by Broadcom Limited with identical electrical and mechanical specifications. Both parts share the same isolation voltage, output characteristics, package, and operating temperature range. Selection between them is based on inventory availability and supply chain considerations.

Q: How do the Vishay TCET parts differ from each other?

A: The TCET series differs in Current Transfer Ratio performance bands. TCET1103 operates at 100–200% @ 10mA, TCET1106 at 100–300% @ 5mA, TCET1107 at 80–160% @ 5mA, TCET1108 at 130–260% @ 5mA, and TCET1109 at 200–400% @ 5mA. All other electrical and mechanical parameters remain constant. Selection depends on the required current transfer ratio for the application circuit.

Q: Are there temperature range differences between Broadcom and Vishay alternatives?

A: Yes. The HCPL-817-00LE and HCPL-817-06LE operate from -30°C to 100°C. All Vishay TCET alternatives extend the lower operating limit to -40°C, providing broader environmental coverage. The upper limit remains 100°C across all parts.

Q: Do all substitute parts use the same 4-DIP package?

A: Yes. All listed substitute parts use 4-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical compatibility with existing PCB layouts and socket designs.

Q: What compliance certifications apply to these substitute parts?

A: All parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). REACH status is Unaffected for all listed components. ECCN classification is EAR99 and HTSUS code is 8541.49.8000 across all parts.
