Substitute Part Grouping Explanation

Substitute parts for the HCPL-817-360E are qualified based on the following critical parameters:

Voltage - Isolation: 5000Vrms minimum (5300Vrms acceptable for enhanced margin)
Output Type: Transistor
Number of Channels: 1
Current Transfer Ratio: 50% minimum @ 5mA, 600% maximum @ 5mA
Current - Output / Channel: 50mA
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing
Rise / Fall Time: 4µs, 3µs

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original HCPL-817-360E. Selection among substitutes should be based on packaging requirements and application-specific output voltage margins.

For applications requiring maximum output voltage headroom, ISP817XSM (80V max) and LTV-816S / LTV-816S-TA1 (80V max) provide enhanced margin over the original 70V specification. These parts are suitable for circuits operating near the upper voltage limits of the HCPL-817-360E.

For applications with output voltage requirements below 35V, LTV-817S, LTV-817S-TA, and LTV-817S-TA1 provide equivalent functionality with extended operating temperature range (-55°C to 110°C) compared to the original part (-30°C to 100°C).

Packaging selection between tube, tape & reel, and cut tape formats should align with production volume and assembly process requirements. All substitute parts are available in equivalent quantities from current inventory.

Frequently Asked Questions (FAQ)

Q: Can LTV-817S be used as a direct replacement for HCPL-817-360E?

A: Yes. LTV-817S maintains identical isolation voltage (5000Vrms), current transfer ratio (50% to 600% @ 5mA), output current (50mA), and switching characteristics (4µs rise, 3µs fall). The 4-SMD gull wing package is mechanically and electrically compatible. The lower maximum output voltage (35V vs 70V) is acceptable for applications not requiring the full voltage margin of the original part.

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

A: These three parts are electrically identical. The differences are packaging format only: LTV-817S is supplied in tube packaging, LTV-817S-TA in tape & reel format, and LTV-817S-TA1 in cut tape with Digi-Reel format. Selection depends on assembly process requirements and volume.

Q: Why does ISP817XSM have a higher isolation voltage (5300Vrms) than the original part?

A: ISP817XSM is manufactured by Isocom Components and exceeds the minimum isolation requirement of 5000Vrms. The higher rating provides additional safety margin and is fully compatible with circuits designed for 5000Vrms isolation. All other electrical parameters remain equivalent.

Q: Are LTV-816S and LTV-816S-TA1 suitable substitutes?

A: Yes. LTV-816S and LTV-816S-TA1 are qualified substitutes with identical isolation voltage, current transfer ratio, and output current specifications. These parts feature maximum output voltage of 80V, exceeding the original 70V specification, and extended operating temperature range (-50°C to 110°C). The difference in part number (816 vs 817) reflects manufacturer series designation but does not affect functional compatibility.

Q: What packaging format should I select for high-volume production?

A: Tape & reel (TR) formats such as LTV-817S-TA and LTV-816S-TA1 are optimized for automated assembly processes. Cut tape formats such as LTV-817S-TA1 provide flexibility for mixed-volume production. Tube packaging is suitable for lower-volume or manual assembly applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the regulatory status of the original HCPL-817-360E.
