Engineering Selection Recommendations

HCPL-T250-560E (Direct Broadcom Substitute)

This part is the direct equivalent of HCPL-T250#560, differing only in packaging format (Tape & Reel versus bulk). Electrical specifications, isolation voltage, propagation delay, and output current are identical. The HCPL-T250-560E is currently active in production with ROHS3 compliance, addressing the discontinued status of the original part. This is the primary substitution choice for applications requiring exact electrical performance matching.

LTV-3150S-TA1 (Lite-On Alternative)

The LTV-3150S-TA1 provides enhanced electrical performance across multiple parameters: 5000Vrms isolation (versus 3750Vrms), 15kV/µs common mode transient immunity (versus 5kV/µs), and faster propagation delay (400ns versus 500ns). Operating temperature range extends to -40°C ~ 105°C. However, peak output current is 1A (versus 1.5A). This part is suitable for applications where higher isolation voltage and improved transient immunity are beneficial, provided the 1A peak output current meets circuit requirements. ROHS3 compliance and active production status are confirmed.

Frequently Asked Questions (FAQ)

Q: Can HCPL-T250-560E be used as a direct replacement for HCPL-T250#560?

A: Yes. Both parts are manufactured by Broadcom Limited with identical electrical specifications: 3750Vrms isolation, 1.5A peak output current, 500ns propagation delay, and 15V ~ 30V output supply voltage. The difference is packaging format (Tape & Reel versus bulk). HCPL-T250-560E is currently in active production.

Q: What are the key differences between HCPL-T250#560 and LTV-3150S-TA1?

A: The LTV-3150S-TA1 offers higher isolation voltage (5000Vrms versus 3750Vrms), superior common mode transient immunity (15kV/µs versus 5kV/µs), and faster propagation delay (400ns versus 500ns). The LTV-3150S-TA1 has a lower peak output current rating (1A versus 1.5A). Both use 8-SMD Gull Wing packages and support 15V ~ 30V output supply voltage.

Q: Is the LTV-3150S-TA1 suitable if my application requires 1.5A peak output current?

A: No. The LTV-3150S-TA1 is rated for 1A peak output current. If your circuit design requires 1.5A peak output capability, use HCPL-T250-560E, which maintains the original 1.5A specification.

Q: Are all three parts RoHS compliant?

A: HCPL-T250#560 is RoHS non-compliant. Both HCPL-T250-560E and LTV-3150S-TA1 are ROHS3 compliant.

Q: Do all parts use the same 8-SMD Gull Wing package?

A: Yes. All three parts use 8-SMD Gull Wing surface mount packages, ensuring mechanical compatibility on PCB layouts designed for the HCPL-T250#560.

Q: What is the difference between HCPL-T250#560 and HCPL-T250-560E packaging?

A: HCPL-T250#560 is supplied in bulk packaging, while HCPL-T250-560E is supplied in Tape & Reel (TR) format. Electrical specifications are identical.
