Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between substitutes depends on application-specific requirements:

LTV-817S Series (Lite-On): Available in three packaging configurations (Tube, Tape & Reel, Cut Tape & Digi-Reel). These parts feature extended operating temperature range (-55°C ~ 110°C) and higher current transfer ratio maximum (600% @ 5mA). Maximum output voltage is 35V, which is lower than the HCPL-817-30LE.

ISP817XSM (Isocom Components): Offers the highest isolation voltage rating (5300Vrms) and maximum output voltage (80V). Operating temperature range matches the HCPL-817-30LE (-30°C ~ 100°C).

LTV-816S Series (Lite-On): Provides maximum output voltage of 80V with extended operating temperature range (-50°C ~ 110°C). Available in Tube and Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can LTV-817S variants replace HCPL-817-30LE in all applications?

A: LTV-817S parts are electrically compatible for isolation voltage, channel count, output type, and switching characteristics. However, the maximum output voltage is 35V compared to 70V for the HCPL-817-30LE. Applications requiring output voltages above 35V require ISP817XSM or LTV-816S series.

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

A: These are identical electrical parts with different packaging formats. LTV-817S is supplied in Tube, LTV-817S-TA in Tape & Reel (TR), and LTV-817S-TA1 in Cut Tape (CT) & Digi-Reel. Selection depends on assembly process requirements and volume.

Q: Is ISP817XSM a direct replacement for HCPL-817-30LE?

A: ISP817XSM meets all primary electrical parameters and exceeds isolation voltage specification (5300Vrms vs. 5000Vrms). The 4-SMD, Gull Wing package is mechanically compatible. Operating temperature range is identical.

Q: Why do substitute parts show higher current transfer ratio maximum (600% vs. 100%)?

A: Current transfer ratio specifications define the range of acceptable performance across manufacturing tolerance. Higher maximum values indicate broader acceptable performance bands and do not affect circuit operation when designed for the minimum specification.

Q: Can I use LTV-816S if I need higher output voltage?

A: Yes. LTV-816S provides 80V maximum output voltage, matching ISP817XSM. Both are suitable for applications exceeding the 70V output capability of HCPL-817-30LE.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the HCPL-817-30LE compliance profile.
