Parameter Comparison

Engineering Selection Recommendations

All qualified substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection between substitutes should be based on inventory availability and specific timing requirements for procurement.

Broadcom ACPL-217-50BE: Direct parametric equivalent with identical electrical specifications and 4-SOIC packaging. Suitable for applications requiring Broadcom component standardization.

Everlight EL3H7(B)(TA)-VG: Meets all critical electrical parameters with improved Vce saturation performance (200mV vs. 400mV). Available in 4-SSOP package variant. Turn-on/turn-off timing data not provided in specifications.

onsemi FODM217BR2 and FODM217BR2V: Functionally equivalent with matching electrical performance. Available in higher inventory quantities (63,284 and 1,862 units respectively). Supplied in Tape & Reel packaging format.

Vishay VOS617A-8T and VOS617A-8X001T: Meet all critical electrical parameters with slightly lower forward voltage (1.18V vs. 1.2V). Slower turn-on/turn-off timing (6µs/4µs vs. 3µs/3µs). Available in 4-SSOP package configuration.

Frequently Asked Questions (FAQ)

Q: Can ACPL-217-56BE be directly replaced with ACPL-217-50BE? A: Yes. Both parts are manufactured by Broadcom Limited and share identical electrical specifications, isolation voltage, current transfer ratios, output voltage, and operating temperature range. Both use 4-SOIC packaging with matching dimensions.

Q: What are the package differences among substitute parts? A: All substitutes use equivalent 4-pin surface mount packages (4-SOIC, 4-SSOP, 4-SOP) with 0.173" width specification. These packages are mechanically compatible for PCB-level substitution. Specific package designations are: ACPL-217-50BE (4-SOIC), EL3H7(B)(TA)-VG (4-SSOP), FODM217BR2/FODM217BR2V (4-SOP), and VOS617A variants (4-SSOP).

Q: Are all substitutes RoHS3 compliant? A: Yes. All qualified substitute parts carry ROHS3 Compliant certification and Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the ACPL-217-56BE.

Q: Which substitute has the best Vce saturation performance? A: The Everlight EL3H7(B)(TA)-VG offers superior Vce saturation at 200mV maximum, compared to 400mV for other substitutes. This lower saturation voltage may provide improved efficiency in switching applications.

Q: What is the difference in switching speed between substitutes? A: The ACPL-217-56BE, ACPL-217-50BE, FODM217BR2, and FODM217BR2V feature turn-on/turn-off times of 3µs/3µs. The Vishay VOS617A variants have slower switching times of 6µs/4µs. Rise/fall times vary between 2µs-5µs across all parts.

Q: Which substitute has the highest inventory availability? A: The onsemi FODM217BR2 has the highest inventory with 63,284 units in stock, followed by VOS617A-8X001T with 4,200 units.

Q: Are all substitutes suitable for the full -55°C to 110°C operating temperature range? A: Yes. All qualified substitutes support the complete -55°C to 110°C operating temperature range specified for the ACPL-217-56BE.
