Engineering Selection Recommendations

All identified substitute parts maintain active production status and ROHS3 compliance with MSL Level 1 rating. Selection between equivalent parts is determined by packaging format availability and operating temperature requirements.

Broadcom Limited HCPL-817 Series: HCPL-817-500E is functionally identical to HCPL-817-300E with identical electrical specifications. Differentiation is packaging format: HCPL-817-500E is supplied in Cut Tape and Digi-Reel format with higher inventory availability (12500 units).

Lite-On Inc. LTV-817 Series: LTV-817S, LTV-817S-TA, and LTV-817S-TA1 provide extended operating temperature range (-55°C ~ 110°C) compared to the HCPL-817-300E (-30°C ~ 100°C). Output voltage maximum is reduced to 35V. These parts are available in Tube, Tape & Reel, and Cut Tape formats respectively.

Isocom Components ISP817XSM: ISP817XSM offers the highest isolation voltage rating (5300Vrms) and maximum output voltage (80V). Operating temperature range matches the HCPL-817-300E (-30°C ~ 100°C). Supplied in Tube packaging.

Lite-On Inc. LTV-816 Series: LTV-816S and LTV-816S-TA1 provide extended operating temperature range (-50°C ~ 110°C) and maximum output voltage of 80V. Available in Tube and Tape & Reel formats respectively.

Frequently Asked Questions (FAQ)

Q: Can HCPL-817-500E directly replace HCPL-817-300E? A: Yes. HCPL-817-500E is electrically and mechanically identical to HCPL-817-300E. The difference is packaging format: HCPL-817-500E uses Cut Tape and Digi-Reel while HCPL-817-300E uses Tube packaging. Both maintain identical electrical performance across all specified parameters.

Q: What is the key difference between Broadcom HCPL-817 and Lite-On LTV-817 optoisolators? A: The LTV-817 series extends the operating temperature range to -55°C ~ 110°C compared to HCPL-817-300E at -30°C ~ 100°C. However, LTV-817 maximum output voltage is 35V versus 70V for HCPL-817-300E. All other electrical parameters remain equivalent.

Q: Is ISP817XSM compatible with HCPL-817-300E applications? A: ISP817XSM is electrically compatible with identical current transfer ratios, rise/fall times, and output current specifications. ISP817XSM provides higher isolation voltage (5300Vrms vs 5000Vrms) and higher maximum output voltage (80V vs 70V). Operating temperature range is identical (-30°C ~ 100°C).

Q: What packaging options are available for equivalent parts? A: Substitute parts are available in three packaging formats: Tube (standard reel), Cut Tape with Digi-Reel (individual tape strips), and Tape & Reel (continuous reel). All formats use identical 4-SMD Gull Wing surface mount package geometry.

Q: Can LTV-816S replace HCPL-817-300E in high-temperature applications? A: LTV-816S extends operating temperature to -50°C ~ 110°C and provides 80V maximum output voltage. All other electrical specifications match HCPL-817-300E. Selection depends on whether the application requires the extended temperature range and higher output voltage capability.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the HCPL-817-300E environmental and regulatory status.
