Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-817-36LE are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of Channels: 1
• Voltage - Isolation: 5000Vrms or higher
• Current Transfer Ratio (Min): 50% @ 5mA or higher
• Output Type: Transistor
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowed Variations:

• Voltage - Isolation: May exceed 5000Vrms
• Current Transfer Ratio (Max): May exceed 100%
• Voltage - Output (Max): May exceed 70V
• Operating Temperature: May extend beyond -30°C ~ 100°C
• Packaging Format: Tube, Tape & Reel (TR), or Cut Tape (CT) & Digi-Reel®

Substitute parts are grouped into three categories: Lite-On LTV-817 series (packaging variants), Lite-On LTV-816 series (extended temperature range), and Isocom ISP817XSM (higher isolation voltage).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

LTV-817S Series (Lite-On): These parts provide direct functional equivalence with extended operating temperature range (-55°C ~ 110°C) compared to the HCPL-817-36LE. The LTV-817S in Tube packaging, LTV-817S-TA in Tape & Reel format, and LTV-817S-TA1 in Cut Tape & Digi-Reel® format are electrically identical, differing only in packaging and supply format. Selection depends on procurement and assembly requirements.

LTV-816S Series (Lite-On): The LTV-816S and LTV-816S-TA1 offer extended operating temperature range (-50°C ~ 110°C) and higher maximum output voltage (80V versus 70V). These parts are suitable for applications requiring broader temperature performance.

ISP817XSM (Isocom): This part provides the highest isolation voltage rating (5300Vrms) and maximum output voltage (80V). Operating temperature range matches the HCPL-817-36LE (-30°C ~ 100°C). Selection is appropriate for applications requiring enhanced isolation specifications.

Frequently Asked Questions (FAQ)

Q: Can LTV-817S series parts directly replace HCPL-817-36LE in existing designs?

A: Yes. The LTV-817S, LTV-817S-TA, and LTV-817S-TA1 maintain identical electrical specifications for isolation voltage, current transfer ratio minimum, output current, and saturation voltage. The primary difference is extended operating temperature range (-55°C ~ 110°C versus -30°C ~ 100°C). Packaging format varies by part number suffix.

Q: What is the difference between LTV-817S, LTV-817S-TA, and LTV-817S-TA1?

A: These parts are electrically identical. LTV-817S is supplied in Tube packaging. LTV-817S-TA is supplied in Tape & Reel (TR) format for automated assembly. LTV-817S-TA1 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly equipment and procurement volume requirements.

Q: Why does ISP817XSM have a higher isolation voltage rating?

A: ISP817XSM is rated for 5300Vrms isolation versus 5000Vrms for the HCPL-817-36LE. This represents a higher isolation specification from Isocom Components. Both parts meet the minimum 5000Vrms requirement and are functionally compatible.

Q: Can I use LTV-816S in place of LTV-817S?

A: Yes, with consideration of output voltage requirements. LTV-816S provides 80V maximum output voltage compared to 35V for LTV-817S. If your circuit operates below 35V, both are compatible. LTV-816S also offers extended temperature range (-50°C ~ 110°C).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, matching the HCPL-817-36LE specifications.

Q: What is the Current Transfer Ratio difference between HCPL-817-36LE and substitute parts?

A: HCPL-817-36LE specifies 100% maximum Current Transfer Ratio at 5mA. All substitute parts specify 600% maximum at 5mA. Both maintain the 50% minimum specification. Higher maximum CTR in substitute parts does not affect compatibility; it represents improved performance margin.
