Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-817-30AE are qualified based on the following criteria:

Primary Matching Parameters:

• Voltage - Isolation: 5000Vrms or higher
• Number of Channels: 1
• Output Type: Transistor
• Package / Case: 4-SMD, Gull Wing
• Mounting Type: Surface Mount
• Input Type: DC
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV

Acceptable Variation Ranges:

• Current Transfer Ratio: Minimum 50% @ 5mA (HCPL-817-30AE specifies 80% minimum; substitutes may have lower minimums but must support circuit requirements)
• Voltage - Output (Max): 35V or higher (HCPL-817-30AE specifies 70V; substitutes with 35V or 80V are acceptable depending on application headroom)
• Operating Temperature: Must encompass or extend the -30°C ~ 100°C range
• Rise / Fall Time: 4µs, 3µs (consistent across all parts)

Substitutes are grouped by packaging configuration (Tube, Tape & Reel, Cut Tape) and manufacturer (Lite-On Inc., Isocom Components) while maintaining electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL Level 1 rating, matching the regulatory and environmental requirements of the HCPL-817-30AE.

LTV-817S Series (Lite-On Inc.): Available in three packaging options (Tube, Tape & Reel, Cut Tape & Digi-Reel). These parts provide extended operating temperature range (-55°C ~ 110°C) and are suitable for applications requiring broader thermal performance. Maximum output voltage is 35V, which is lower than the HCPL-817-30AE; circuit designs must accommodate this constraint.

ISP817XSM (Isocom Components): Offers the highest isolation voltage rating (5300Vrms) and maximum output voltage (80V), providing additional design margin. Operating temperature range matches the HCPL-817-30AE (-30°C ~ 100°C). This part is recommended for applications requiring enhanced isolation performance or higher output voltage headroom.

LTV-816S Series (Lite-On Inc.): Available in Tube and Tape & Reel packaging. Provides maximum output voltage of 80V and extended operating temperature range (-50°C ~ 110°C). These parts offer performance characteristics between the LTV-817S and ISP817XSM options.

Frequently Asked Questions (FAQ)

Q: Can LTV-817S parts substitute for HCPL-817-30AE in all applications?

A: LTV-817S parts are electrically equivalent for isolation voltage, channel count, output type, and switching characteristics. However, the maximum output voltage is 35V compared to 70V for the HCPL-817-30AE. Substitution is valid only if circuit design does not require output voltages exceeding 35V.

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

A: These part numbers represent the same electrical device in different packaging configurations. LTV-817S is supplied in Tube packaging, LTV-817S-TA in Tape & Reel (TR), and LTV-817S-TA1 in Cut Tape (CT) & Digi-Reel. Electrical performance is identical; selection depends on assembly process requirements and volume.

Q: Why does ISP817XSM have a higher isolation voltage rating (5300Vrms)?

A: ISP817XSM is manufactured by Isocom Components and meets a higher isolation specification. This provides additional safety margin in high-voltage isolation applications. The part is functionally equivalent to HCPL-817-30AE and can be used as a direct substitute with enhanced isolation performance.

Q: Are all substitute parts surface mount compatible with HCPL-817-30AE PCB layouts?

A: Yes. All substitute parts use 4-SMD, Gull Wing package configuration with surface mount technology, matching the HCPL-817-30AE footprint and assembly process requirements.

Q: What is the impact of different current transfer ratio specifications?

A: HCPL-817-30AE specifies 80% minimum CTR @ 5mA, while substitute parts specify 50% minimum. Lower minimum CTR values indicate broader device tolerance. Circuit designs must account for the lower guaranteed minimum when calculating input current requirements, though typical performance across all parts is similar.

Q: Can LTV-816S parts be used interchangeably with LTV-817S parts?

A: Both LTV-816S and LTV-817S are single-channel 5000Vrms optoisolators with identical switching characteristics and output current ratings. The primary difference is maximum output voltage: LTV-816S supports 80V while LTV-817S supports 35V. Selection depends on circuit output voltage requirements.
