Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance with REACH unaffected designation. Selection between substitutes is determined by packaging and inventory requirements:

LTV-814HS and LTV-814HS-TA1 are suitable for applications requiring higher maximum forward current (150 mA) and support higher input current levels (100 mA reference). These parts differ in packaging format only (Tube versus Tape & Reel).

LTV-814S, LTV-814S-TA, and LTV-814S-TA1 maintain electrical characteristics closer to the original HCPL-814-56AE, with identical forward voltage (1.2V) and maximum forward current (50 mA). These parts offer extended operating temperature range (-30°C to 110°C) and are available in multiple packaging formats. The LTV-814S-TA1 variant provides the highest inventory availability at 60,300 units.

Frequently Asked Questions (FAQ)

Q: Can LTV-814HS parts replace HCPL-814-56AE in all applications?

A: LTV-814HS parts are electrically compatible for isolation voltage, output type, and package footprint. However, they operate at different current transfer ratio specifications (20-80% @ 100mA versus 50-150% @ 1mA). Verify that your circuit design accommodates these parameter differences before substitution.

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

A: LTV-814S parts support maximum forward current of 50 mA and offer extended operating temperature range to 110°C. LTV-814HS parts support maximum forward current of 150 mA with standard operating temperature range to 100°C. Both maintain 5000Vrms isolation and identical package specifications.

Q: How do packaging formats affect component selection?

A: Packaging format (Tube, Tape & Reel, or Cut Tape) affects assembly process compatibility and inventory handling but does not alter electrical performance. Select based on your manufacturing equipment and supply chain requirements. All formats use identical 4-SMD, Gull Wing package footprints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original HCPL-814-56AE.

Q: Which substitute offers the best inventory availability?

A: LTV-814S-TA1 provides the highest inventory level at 60,300 units in stock, followed by HCPL-814-56AE at 45,300 units.
