Engineering Selection Recommendations

All four parts listed are active production components with ROHS3 compliance and REACH unaffected status. The ACPL-217-56DE and ACPL-217-50DE are both Broadcom Limited products with identical electrical specifications; selection between them depends on packaging and supply requirements. The FODM217DR2 and FODM217DR2V from onsemi provide equivalent electrical performance and are suitable alternatives when Broadcom parts are unavailable. The FODM217DR2V exhibits a minor timing variation in fall time (3µs versus 2µs for other variants) but remains within functional equivalence for the specified application parameters. All parts are surface mount compatible with 4-SOIC/4-SOP package form factors and support the full operating temperature range of -55°C to 110°C.

Frequently Asked Questions (FAQ)

Q: Can ACPL-217-50DE be used as a direct replacement for ACPL-217-56DE?

A: Yes. Both parts are manufactured by Broadcom Limited and share identical electrical specifications including isolation voltage (3750Vrms), current transfer ratio (300-600% @ 5mA), output voltage (80V max), and output current (50mA). The difference is packaging format; ACPL-217-50DE is supplied in Cut Tape & Digi-Reel format.

Q: Are onsemi FODM217 parts compatible with Broadcom ACPL-217 parts?

A: Yes. FODM217DR2 and FODM217DR2V are parametric equivalents with matching electrical performance across all critical parameters: isolation voltage, current transfer ratio, output characteristics, and operating temperature range. Both use 4-SOP packaging, which is mechanically compatible with the 4-SOIC form factor.

Q: What is the difference between FODM217DR2 and FODM217DR2V?

A: Both parts are onsemi products with identical electrical specifications. The only documented difference is the fall time specification: FODM217DR2 specifies 3µs typical fall time, while FODM217DR2V specifies 3µs typical fall time (matching the main part specification of 2µs, 3µs for turn on/off times).

Q: Are all substitute parts RoHS compliant?

A: Yes. All four parts (ACPL-217-56DE, ACPL-217-50DE, FODM217DR2, and FODM217DR2V) are ROHS3 compliant and REACH unaffected.

Q: What is the maximum operating temperature for these optoisolators?

A: All parts support an operating temperature range of -55°C to 110°C, enabling use in industrial and extended temperature applications.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, provided the PCB layout accommodates the 4-SOIC/4-SOP package form factor (0.173" width, 4.40mm). Pin configurations are identical across all variants, supporting direct substitution.
