HCPL-817-00CE Equivalent & Substitute Parts

Part Overview

The HCPL-817-00CE is a 5000Vrms optoisolator with transistor output manufactured by Broadcom Limited. This single-channel, 4-DIP through-hole component is designed for high-voltage isolation applications requiring galvanic separation between input and output circuits. The part is active and in production, with 1259 units currently in stock. Substitute parts are necessary when addressing supply chain constraints, inventory availability, or when design specifications allow for alternative Current Transfer Ratio (CTR) grades or operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-817-00CE is determined by the following critical parameters:

• Voltage - Isolation: Must equal 5000Vrms
• Package / Case: Must be 4-DIP (0.300", 7.62mm) for through-hole mounting compatibility
• Output Type: Must be Transistor
• Number of Channels: Must be 1
• Current - Output / Channel: Must support 50mA minimum
• Current Transfer Ratio (CTR): Acceptable range depends on application requirements; parts with CTR Min ≥ 50% @ 5mA and CTR Max ≥ 160% @ 5mA are functionally equivalent
• Operating Temperature Range: Extended ranges (-55°C to 110°C) are backward compatible with the base range (-30°C to 100°C)
• Compliance: All substitutes must maintain ROHS3 compliance and EAR99 classification

The HCPL-817-06CE is a parametric equivalent from the same manufacturer. The Vishay TCET series (TCET1103, TCET1106, TCET1107, TCET1108, TCET1109) and Lite-On LTV-817 provide cross-manufacturer alternatives with identical isolation voltage, package, and output specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Parametric Match): HCPL-817-06CE is the primary substitute, offering identical electrical specifications and operating temperature range as the HCPL-817-00CE. Both are Broadcom products with ROHS3 compliance and active production status. Inventory availability is higher for the HCPL-817-06CE (2300 units).

Cross-Manufacturer Alternatives:

Lite-On LTV-817 is suitable when extended operating temperature range (-55°C to 110°C) is required. Note that maximum output voltage is 35V compared to 70V for Broadcom and Vishay parts. This part has the highest inventory availability (565,646 units).

Vishay TCET1109 provides the closest CTR match to the HCPL-817-00CE (200% to 400% @ 5mA) with extended temperature range (-40°C to 100°C) and higher inventory (35,300 units). Vce saturation is 300mV versus 200mV for the Broadcom part.

Vishay TCET1108 offers a mid-range CTR (130% to 260% @ 5mA) with the highest inventory among Vishay options (45,200 units).

Vishay TCET1106 and TCET1107 provide lower CTR grades (100% to 300% and 80% to 160% respectively) suitable for applications with less stringent current transfer requirements.

Vishay TCET1103 operates at 10mA test current with CTR range of 100% to 200%, requiring circuit design consideration for the different test condition.

All substitutes maintain ROHS3 compliance, EAR99 classification, and MSL Level 1 rating. Selection should be based on CTR grade requirements, output voltage limits, and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can HCPL-817-06CE be used as a direct replacement for HCPL-817-00CE? A: Yes. Both parts are manufactured by Broadcom, share identical isolation voltage (5000Vrms), package (4-DIP), CTR specifications (200% to 400% @ 5mA), and operating temperature range (-30°C to 100°C). They are parametric equivalents.

Q: What is the main difference between Broadcom HCPL-817 and Vishay TCET series optoisolators? A: The primary differences are CTR grades and Vce saturation voltage. Broadcom HCPL-817-00CE has Vce saturation of 200mV maximum, while Vishay TCET series parts specify 300mV maximum. CTR specifications vary by TCET model grade. All maintain 5000Vrms isolation and 4-DIP packaging.

Q: Is the Lite-On LTV-817 compatible with the HCPL-817-00CE? A: The LTV-817 is pin-compatible and maintains 5000Vrms isolation and 4-DIP packaging. However, maximum output voltage is limited to 35V compared to 70V for the HCPL-817-00CE. Verify that your application does not require output voltages above 35V before substitution.

Q: Why do some substitute parts have different CTR test currents? A: Current Transfer Ratio is measured at a specified input current. TCET1103 is tested at 10mA while most other parts are tested at 5mA. Circuit design must account for the test current condition when selecting a substitute based on CTR specifications.

Q: Are all listed substitutes ROHS3 compliant? A: Yes. All substitute parts listed—HCPL-817-06CE, LTV-817, TCET1103, TCET1106, TCET1107, TCET1108, and TCET1109—are ROHS3 compliant with MSL Level 1 rating and EAR99 classification.

Q: Which substitute has the best inventory availability? A: Lite-On LTV-817 has the highest inventory at 565,646 units. Among Vishay options, TCET1108 has 45,200 units available. Broadcom HCPL-817-06CE has 2,300 units in stock.

Q: Can I use TCET1107 if my design requires high CTR? A: TCET1107 has a CTR range of 80% to 160% @ 5mA, which is lower than the HCPL-817-00CE (200% to 400% @ 5mA). Use TCET1109 (200% to 400% @ 5mA) or TCET1108 (130% to 260% @ 5mA) for higher CTR requirements.
