Engineering Selection Recommendations

All three parts—SI8716BC-A-IP, SI8715BC-A-IP, and SI8719BC-A-IP—are active products from Skyworks Solutions Inc. with identical electrical specifications and packaging requirements. Selection between these parts is based on availability and procurement logistics rather than technical differentiation.

SI8715BC-A-IP and SI8719BC-A-IP carry explicit RoHS3 compliance certification in their documentation. SI8716BC-A-IP does not include this certification statement in the provided parameters. For applications requiring documented RoHS3 compliance, SI8715BC-A-IP or SI8719BC-A-IP are the appropriate selections.

All parts are classified under ECCN EAR99 and HTSUS code 8542.39.0001, with identical moisture sensitivity specifications (MSL 3, 168 hours).

Frequently Asked Questions (FAQ)

Q: Can SI8715BC-A-IP or SI8719BC-A-IP be used as direct replacements for SI8716BC-A-IP?

A: Yes. All three parts share identical electrical parameters, isolation voltage, data rate, timing specifications, supply voltage range, operating temperature range, and 8-SMD Gull Wing package configuration. Direct substitution is supported at the circuit board level without design modification.

Q: Are there differences in RoHS compliance between these parts?

A: SI8715BC-A-IP and SI8719BC-A-IP are explicitly documented as ROHS3 Compliant. SI8716BC-A-IP does not include RoHS compliance certification in the provided specifications. For applications with RoHS compliance requirements, SI8715BC-A-IP or SI8719BC-A-IP should be specified.

Q: Do these parts have different pin configurations or package footprints?

A: No. All three parts use the 8-SMD, Gull Wing package with identical mechanical and electrical pin assignments. PCB footprints are interchangeable.

Q: What is the moisture sensitivity level for these components?

A: All three parts are rated MSL 3 with a 168-hour floor life. Standard moisture control procedures during storage and handling apply equally to all variants.

Q: Are there supply voltage or operating temperature differences?

A: No. All parts operate across the identical supply voltage range of 2.5V to 5.5V and temperature range of -40°C to 125°C.

Q: Which part should be selected for new designs?

A: Selection should be based on component availability and procurement requirements. For applications requiring documented RoHS3 compliance, SI8715BC-A-IP or SI8719BC-A-IP are preferred. All parts are active products suitable for new designs.
