HCPL-814-50AE Equivalent & Substitute Parts

Part Overview

The HCPL-814-50AE is a 5000Vrms optoisolator with transistor output manufactured by Broadcom Limited. This single-channel device is designed for high-voltage isolation applications requiring AC or DC input capability. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent isolation voltage, channel configuration, output type, and mounting specifications are maintained across the product lifecycle or when sourcing constraints require alternative manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the HCPL-814-50AE are qualified based on the following critical parameters that must remain constant:

Voltage - Isolation: 5000Vrms (mandatory match)
Number of Channels: 1 (mandatory match)
Output Type: Transistor (mandatory match)
Mounting Type: Surface Mount (mandatory match)
Package / Case: 4-SMD, Gull Wing (mandatory match)
Input Type: AC, DC (mandatory match)

The substitute parts listed below maintain these core electrical and mechanical specifications. Variations in Current Transfer Ratio, output current capacity, forward voltage, and operating temperature range are permitted within the optoisolator product family, as these parameters do not affect the fundamental isolation function or physical compatibility in standard circuit applications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full RoHS3 compliance. Selection between the HCPL-814-50AE and Lite-On LTV-814 series variants depends on packaging requirements and inventory availability:

HCPL-814-50AE (Broadcom): Original specification part supplied in Tape & Reel packaging. Maintains 50mA output current and 1.2V typical forward voltage.

LTV-814HS and LTV-814HS-TA1 (Lite-On): Support higher output current (80mA) and forward current (150mA maximum). LTV-814HS-TA1 provides Tape & Reel packaging equivalent to the original part. LTV-814HS is supplied in Tube packaging.

LTV-814S and LTV-814S-TA1 (Lite-On): Match the original part's 50mA output current and 1.2V forward voltage specifications. Operating temperature range extends to 110°C. LTV-814S-TA1 is available in Cut Tape and Digi-Reel packaging with highest inventory availability. LTV-814S is supplied in Tube packaging.

All substitute parts are electrically and mechanically compatible with the HCPL-814-50AE in standard 5000Vrms isolation applications.

Frequently Asked Questions (FAQ)

Q: Can LTV-814HS replace HCPL-814-50AE in all applications?

A: LTV-814HS maintains the same isolation voltage (5000Vrms), channel count (1), output type (transistor), and package (4-SMD, Gull Wing). The primary difference is increased output current capacity (80mA vs. 50mA) and higher forward voltage (1.4V vs. 1.2V). Compatibility depends on circuit design requirements for these parameters.

Q: What is the difference between LTV-814S and LTV-814HS?

A: Both are Lite-On optoisolators with 5000Vrms isolation. LTV-814S matches the original HCPL-814-50AE output current (50mA) and forward voltage (1.2V), with extended operating temperature to 110°C. LTV-814HS provides higher output current (80mA) and forward current capacity (150mA maximum) but operates to 100°C maximum.

Q: Does packaging affect electrical performance?

A: Packaging format (Tape & Reel, Tube, Cut Tape, Digi-Reel) does not affect electrical performance. Selection is based on assembly process requirements and inventory management. All variants maintain identical electrical specifications within their respective product lines.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The HCPL-814-50AE and all listed Lite-On substitutes (LTV-814HS, LTV-814HS-TA1, LTV-814S, LTV-814S-TA1) are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which substitute part has the highest inventory availability?

A: LTV-814S-TA1 is available with 60,300 pieces in stock, the highest among all listed alternatives.
