Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI8711CC-AS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Isolation voltage rating: 3750Vrms
• Channel configuration: 1 channel, unidirectional
• Data rate: 1Mbps
• Common mode transient immunity: 20kV/µs minimum
• Supply voltage range: 3V ~ 30V
• Operating temperature range: -40°C ~ 125°C
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Automotive grade qualification: AEC-Q100
• Technology platform: Capacitive coupling

The SI8710CC-AS meets all mandatory matching parameters and qualifies as a parametric equivalent. Both devices share identical electrical specifications, thermal ratings, isolation characteristics, and packaging requirements. The substitution is based on complete parameter alignment within the Skyworks Solutions automotive digital isolator product family.

Parameter Comparison

Engineering Selection Recommendations

Both SI8711CC-AS and SI8710CC-AS are Active products manufactured by Skyworks Solutions Inc. with identical AEC-Q100 automotive qualifications. Selection between these parts should be based on availability and supply chain requirements.

SI8711CC-AS is appropriate when current inventory of 647 units meets project lead time and volume requirements.

SI8710CC-AS is appropriate as a substitute when SI8711CC-AS availability is constrained. With 1813 units in stock, this part provides enhanced supply security. The higher inventory level of SI8710CC-AS supports extended production schedules and mitigates supply chain risk without compromising electrical or thermal performance.

Both parts are qualified to identical automotive standards and carry equivalent compliance certifications (AEC-Q100, ECCN EAR99, HTSUS 8542.39.0001). PCB layout, thermal management, and signal integrity considerations remain unchanged between these substitutes.

Frequently Asked Questions (FAQ)

Q: Can SI8710CC-AS be used as a direct replacement for SI8711CC-AS in automotive applications?

A: Yes. Both parts are parametrically identical across all electrical specifications, isolation ratings, timing characteristics, and automotive qualifications. Direct substitution is supported without circuit redesign or re-qualification.

Q: Are there differences in package dimensions between these parts?

A: No. Both SI8711CC-AS and SI8710CC-AS use identical 8-SOIC packaging with 0.154" body width and 3.90mm overall width. PCB footprints, solder pad layouts, and mounting requirements are identical.

Q: What is the basis for substitution between SI8711CC-AS and SI8710CC-AS?

A: Substitution is based on complete electrical equivalence. Both devices share identical isolation voltage (3750Vrms), channel configuration (1 unidirectional), data rate (1Mbps), common mode transient immunity (20kV/µs), supply voltage range (3V ~ 30V), operating temperature range (-40°C ~ 125°C), and automotive grade qualification (AEC-Q100).

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 3 with 168-hour floor life. Storage, handling, and reflow procedures are identical.

Q: Are there any electrical performance differences in propagation delay or timing characteristics?

A: No. Propagation delay (tpLH/tpHL), pulse width distortion, and rise/fall time specifications are identical between SI8711CC-AS and SI8710CC-AS.

Q: Which part should be selected for new designs?

A: Either part is appropriate for new designs. Selection should be based on current inventory availability and supply chain lead time requirements. Both parts carry Active product status and identical automotive qualifications.
