Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the HCPL-817-36AE.

Lite-On LTV-817 Series (LTV-817S, LTV-817S-TA, LTV-817S-TA1): These parts provide extended operating temperature range (-55°C to 110°C) compared to the HCPL-817-36AE (-30°C to 100°C). Maximum output voltage is 35V, which is lower than the original part's 70V specification. Selection among these three variants depends on packaging format requirements: Tube for standard applications, Tape & Reel for high-volume automated assembly, or Cut Tape & Digi-Reel for mixed-volume procurement.

Isocom ISP817XSM: This part offers the highest isolation voltage specification at 5300Vrms and maximum output voltage of 80V, exceeding the HCPL-817-36AE's 70V rating. Operating temperature range matches the original part (-30°C to 100°C). Tube packaging is provided.

Lite-On LTV-816 Series (LTV-816S, LTV-816S-TA1): These parts provide extended operating temperature range (-50°C to 110°C) and maximum output voltage of 80V. Selection between Tube and Tape & Reel packaging depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can LTV-817S parts with 35V maximum output voltage replace the HCPL-817-36AE in applications requiring 70V output?

A: No. The LTV-817S maximum output voltage of 35V is insufficient for applications designed for the HCPL-817-36AE's 70V capability. ISP817XSM or LTV-816 series parts with 80V maximum output voltage are appropriate for such applications.

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

A: These three part numbers represent the same electrical device with different packaging formats. LTV-817S is supplied in Tube packaging for standard quantities. LTV-817S-TA is supplied in Tape & Reel format for high-volume automated pick-and-place assembly. LTV-817S-TA1 is supplied in Cut Tape & Digi-Reel format for mixed-volume orders. Electrical specifications and performance are identical.

Q: Are the substitute parts pin-compatible with the HCPL-817-36AE?

A: All substitute parts use the same 4-SMD gull wing package configuration. Pin compatibility is maintained across all listed alternatives.

Q: Which substitute part offers the widest operating temperature range?

A: The LTV-817S series (all three packaging variants) and LTV-816S series offer the widest operating temperature ranges at -55°C to 110°C and -50°C to 110°C respectively, compared to the HCPL-817-36AE's -30°C to 100°C range.

Q: What is the significance of the Current Transfer Ratio variation between parts?

A: The HCPL-817-36AE specifies 80% to 160% CTR @ 5mA, while substitute parts specify 50% to 600% CTR @ 5mA. The substitute parts have a wider acceptable range, which provides greater design flexibility but requires circuit design verification to ensure proper operation within the application's specific requirements.

Q: Is the ISP817XSM isolation voltage of 5300Vrms a functional advantage over 5000Vrms?

A: The ISP817XSM's 5300Vrms isolation exceeds the HCPL-817-36AE's 5000Vrms specification. This provides additional isolation margin in high-voltage applications but does not represent a functional requirement change for designs already qualified to 5000Vrms isolation.
