Engineering Selection Recommendations

All substitute parts maintain active product status and full RoHS3 compliance, ensuring regulatory equivalence with the HCPL-814-36AE. The LTV-814 series from Lite-On Inc. provides direct functional substitution across all critical electrical parameters.

LTV-814HS and LTV-814HS-TA1 support higher maximum output current (80mA versus 50mA), providing additional design margin for applications requiring higher load current. These variants are suitable for designs where increased output current capacity is beneficial or required.

LTV-814S, LTV-814S-TA, and LTV-814S-TA1 maintain identical maximum output current (50mA) and forward voltage characteristics to the HCPL-814-36AE, offering direct pin-compatible replacement. The LTV-814S series extends the operating temperature range to 110°C, providing enhanced thermal performance for high-temperature environments.

Packaging format selection (Tube, Tape & Reel, or Cut Tape & Digi-Reel®) depends on manufacturing process requirements and volume considerations. All packaging formats are compatible with standard surface mount assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can LTV-814HS parts replace HCPL-814-36AE in existing designs?

A: Yes. The LTV-814HS maintains all critical electrical parameters including 5000Vrms isolation, 35V maximum output voltage, 200mV Vce saturation, and identical package configuration. The higher maximum output current (80mA) is a superset capability and does not affect compatibility.

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

A: The primary difference is maximum output current per channel: LTV-814S supports 50mA (matching HCPL-814-36AE), while LTV-814HS supports 80mA. Both maintain identical isolation voltage, output voltage, and saturation characteristics. LTV-814S variants also extend the operating temperature range to 110°C.

Q: Are packaging format differences significant for substitution?

A: Packaging format (Tube, Tape & Reel, Cut Tape & Digi-Reel®) affects manufacturing and handling processes but does not impact electrical performance or circuit compatibility. Selection depends on assembly line requirements and volume needs. All formats use identical 4-SMD, Gull Wing package geometry.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All LTV-814 series substitutes are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the HCPL-814-36AE compliance profile. REACH status is unaffected for all variants.

Q: Can LTV-814S-TA1 be used in applications requiring -30°C to 100°C operation?

A: Yes. The LTV-814S-TA1 operating range of -30°C to 110°C encompasses the -30°C to 100°C requirement, providing full compatibility and additional thermal margin.
