Engineering Selection Recommendations

HCPL-T250-360E (Broadcom Limited)

This part is the direct equivalent of the HCPL-T250#360, maintaining identical electrical specifications and package configuration. It is currently in active production status with ROHS3 compliance. Selection of this substitute eliminates supply chain discontinuation risk while preserving all electrical and thermal operating parameters. Inventory availability is confirmed at 743 pieces.

LTV-3150S-TA1 (Lite-On Inc.)

This cross-manufacturer substitute provides enhanced electrical performance relative to the original specification. The isolation voltage rating of 5000Vrms exceeds the 3750Vrms requirement. Common mode transient immunity is rated at 15kV/µs compared to 5kV/µs, and propagation delay is reduced to 400ns. The peak output current specification of 1A is lower than the original 1.5A; however, the output high and low current ratings of 800mA each remain within acceptable gate driver operating ranges for most applications. Operating temperature range extends to -40°C ~ 105°C, providing broader thermal coverage. ROHS3 compliance and active product status are confirmed. Inventory availability is 2360 pieces.

Selection between these substitutes depends on application requirements for peak output current and thermal operating range. Both maintain the mandatory 8-SMD Gull Wing package footprint and 15V ~ 30V output supply voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can HCPL-T250-360E be used as a direct replacement for HCPL-T250#360?

A: Yes. Both parts are manufactured by Broadcom Limited and share identical electrical specifications, isolation voltage, propagation delay, peak output current, and package configuration. The primary difference is product status: HCPL-T250-360E is in active production while HCPL-T250#360 is discontinued.

Q: What is the key limitation of LTV-3150S-TA1 as a substitute?

A: The peak output current rating is 1A compared to the original 1.5A specification. Applications requiring sustained peak current output above 1A may require circuit redesign or thermal management verification. The output high and low current ratings of 800mA each remain available for gate drive applications.

Q: Are all substitutes compatible with the original 8-SMD Gull Wing package footprint?

A: Yes. All listed substitutes use the 8-SMD Gull Wing package configuration, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the HCPL-T250#360.

Q: Does LTV-3150S-TA1 provide improved isolation performance?

A: Yes. The isolation voltage rating of 5000Vrms exceeds the original 3750Vrms specification. Common mode transient immunity is also enhanced at 15kV/µs compared to 5kV/µs, providing superior noise immunity in high-speed switching applications.

Q: What is the operating temperature range difference between substitutes?

A: The original HCPL-T250#360 operates from -20°C to 85°C. HCPL-T250-360E maintains this range. LTV-3150S-TA1 extends the range to -40°C ~ 105°C, providing broader thermal coverage for industrial and extended-temperature applications.

Q: Are both substitutes RoHS compliant?

A: HCPL-T250-360E and LTV-3150S-TA1 are both ROHS3 compliant. The original HCPL-T250#360 is RoHS non-compliant, making either substitute preferable for applications requiring RoHS certification.
