Substitute parts are grouped into three categories:

Upgrade Substitutes (Lite-On LTV-817 Series): LTV-817S, LTV-817S-TA, and LTV-817S-TA1 differ in packaging format (Tube, Tape & Reel, Cut Tape) but maintain identical electrical specifications. These parts feature extended operating temperature range (-55°C ~ 110°C) and lower maximum output voltage (35V vs 70V).

Manufacturer Recommended Substitutes: LTV-816S and LTV-816S-TA1 (Lite-On LTV-816 Series) and ISP817XSM (Isocom) provide alternative sourcing with compatible isolation voltage and output characteristics. LTV-816S variants support extended temperature range (-50°C ~ 110°C) and higher maximum output voltage (80V). ISP817XSM offers higher isolation voltage (5300Vrms) and maximum output voltage (80V).

Parametric Equivalent: HCPL-817-36CE is a direct Broadcom equivalent with identical electrical specifications and operating temperature range, differing only in internal current transfer ratio binning.

Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, consistent with the HCPL-817-30CE. Selection between substitutes depends on specific application requirements:

For applications requiring extended operating temperature range below -30°C or above 100°C, the LTV-817 series (-55°C ~ 110°C), LTV-816 series (-50°C ~ 110°C), or ISP817XSM (-30°C ~ 100°C) are suitable alternatives. The LTV-817S-TA variant offers the highest inventory availability (9665 units) in Tape & Reel format for high-volume production.

For applications with output voltage requirements exceeding 70V, LTV-816S, LTV-816S-TA1, or ISP817XSM (80V maximum) provide higher voltage capability. ISP817XSM additionally offers 5300Vrms isolation voltage, exceeding the 5000Vrms specification of the main part.

The HCPL-817-36CE provides direct parametric equivalence within the Broadcom product line with identical operating temperature range and output voltage specifications, differing only in current transfer ratio binning characteristics.

All parts are active products with confirmed inventory availability and maintain identical mechanical compatibility with 4-SMD, Gull Wing surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can LTV-817S series parts directly replace HCPL-817-30CE in existing designs?

A: LTV-817S, LTV-817S-TA, and LTV-817S-TA1 are mechanically and electrically compatible for applications operating within -55°C to 110°C temperature range and requiring maximum output voltage of 35V or less. The 4-SMD Gull Wing package is identical. Current transfer ratio specifications differ (50-600% vs 200-400%), which may affect circuit design margins but does not prevent substitution in properly designed circuits.

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

A: These three parts are electrically identical but differ in packaging format. LTV-817S is supplied in Tube packaging, LTV-817S-TA in Tape & Reel (TR) format, and LTV-817S-TA1 in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and volume needs. LTV-817S-TA offers the highest inventory (9665 units).

Q: Is ISP817XSM a suitable substitute for high-voltage applications?

A: ISP817XSM is suitable for applications requiring maximum output voltage of 80V (compared to 70V for HCPL-817-30CE) and offers higher isolation voltage (5300Vrms vs 5000Vrms). Operating temperature range is identical (-30°C ~ 100°C). All other electrical parameters are compatible.

Q: Why do LTV-816S and LTV-816S-TA1 have higher maximum output voltage?

A: LTV-816S and LTV-816S-TA1 support 80V maximum output voltage compared to 70V for HCPL-817-30CE. These parts are suitable for applications requiring higher output voltage capability while maintaining all other electrical specifications including 5000Vrms isolation, 50mA output current, and 200mV Vce saturation.

Q: Can I use HCPL-817-36CE as a direct replacement?

A: HCPL-817-36CE is a parametric equivalent within the Broadcom HCPL-817 product line. It maintains identical isolation voltage (5000Vrms), output voltage (70V), operating temperature (-30°C ~ 100°C), and all mechanical specifications. The primary difference is current transfer ratio binning (200-400% vs other variants), which does not affect mechanical compatibility or basic functional operation.

Q: What are the key parameters that determine substitution compatibility?

A: Critical parameters for substitution are: 5000Vrms minimum isolation voltage, single channel configuration, transistor output type, 50mA output current capability, 4-SMD Gull Wing package, surface mount mounting type, and 200mV maximum Vce saturation. All listed substitutes meet these requirements. Secondary parameters such as operating temperature range and maximum output voltage may vary based on application needs.
