SI8630ED-ASR Equivalent & Substitute Parts

Part Overview

The SI8630ED-ASR is an automotive-grade general purpose digital isolator manufactured by Skyworks Solutions Inc. This 3-channel capacitive coupling isolator provides 5000Vrms isolation with 150Mbps data rate capability and 60kV/µs common mode transient immunity. The device is packaged in 16-SOIC (0.295", 7.50mm Width) surface mount configuration and qualified to AEC-Q100 automotive standards. The SI8630ED-ASR is active product status with 1054 units in current inventory. Substitute parts are identified based on matching electrical isolation characteristics, data rate performance, supply voltage compatibility, and identical package form factor while accommodating variations in channel count and CMTI specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SI8630ED-ASR are qualified based on the following critical parameters that determine functional compatibility:

Matching Parameters (Required for Substitution):

• Isolation voltage: 5000Vrms
• Data rate: 150Mbps
• Supply voltage range: 2.5V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C
• Package form factor: 16-SOIC (0.295", 7.50mm Width)
• Technology: Capacitive Coupling
• Mounting type: Surface Mount
• Manufacturer: Skyworks Solutions Inc.

Allowable Variations:

• Number of channels: 3-channel (main part) to 2-channel (substitute parts)
• Common Mode Transient Immunity: 60kV/µs (main part) to 35kV/µs (substitute parts)
• Packaging format: Tape & Reel (TR) to Cut Tape (CT) & Digi-Reel®

The SI8630ED-ASR with 3 channels and 60kV/µs CMTI can be substituted with 2-channel variants (SI8620ED-B-ISR, SI8620BD-B-ISR) in applications where fewer isolation channels are required and lower CMTI performance is acceptable. All substitute parts maintain identical isolation voltage, data rate, supply voltage, temperature range, and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

SI8620ED-B-ISR Selection Criteria: The SI8620ED-B-ISR is suitable for applications requiring 2-channel isolation with Tape & Reel packaging. This part maintains all critical electrical parameters matching the SI8630ED-ASR including 5000Vrms isolation, 150Mbps data rate, 2.5V to 5.5V supply voltage range, and -40°C to 125°C operating temperature. The SI8620ED-B-ISR is active product status with 18950 units in inventory. The reduced CMTI specification of 35kV/µs versus 60kV/µs on the main part is acceptable in applications where common mode transient performance requirements are less stringent. RoHS3 compliance and REACH unaffected status are confirmed.

SI8620BD-B-ISR Selection Criteria: The SI8620BD-B-ISR provides equivalent electrical performance to SI8620ED-B-ISR with Cut Tape and Digi-Reel® packaging format. This part is appropriate for applications where alternative packaging delivery is preferred. The SI8620BD-B-ISR is active product status with 22900 units in inventory, providing higher stock availability. RoHS3 compliance and REACH unaffected status are confirmed.

Channel Count Consideration: Selection between 3-channel (SI8630ED-ASR) and 2-channel (SI8620ED-B-ISR, SI8620BD-B-ISR) variants depends on circuit isolation requirements. The 3-channel configuration provides three independent isolation channels, while 2-channel variants provide two isolation channels. Designs requiring only two isolation channels can utilize the substitute parts without functional limitation.

Frequently Asked Questions (FAQ)

Q: Can SI8620ED-B-ISR or SI8620BD-B-ISR directly replace SI8630ED-ASR in automotive applications?

A: Direct replacement is possible only in applications requiring 2-channel isolation. Both substitute parts maintain AEC-Q100 automotive qualification, 5000Vrms isolation voltage, 150Mbps data rate, identical supply voltage range (2.5V ~ 5.5V), and operating temperature range (-40°C ~ 125°C). The identical 16-SOIC package form factor ensures PCB layout compatibility. Applications designed for 3-channel isolation require the SI8630ED-ASR or equivalent 3-channel device.

Q: What is the difference between SI8620ED-B-ISR and SI8620BD-B-ISR?

A: The primary difference is packaging format. SI8620ED-B-ISR is supplied in Tape & Reel (TR) format, while SI8620BD-B-ISR is supplied in Cut Tape (CT) & Digi-Reel® format. All electrical parameters, operating characteristics, and performance specifications are identical. Selection depends on manufacturing process requirements and inventory management preferences.

Q: How does the 35kV/µs CMTI on substitute parts compare to the 60kV/µs on SI8630ED-ASR?

A: Common Mode Transient Immunity (CMTI) specifies the maximum rate of change of common mode voltage that the isolator can withstand without introducing errors. The SI8630ED-ASR specification of 60kV/µs provides higher immunity to fast transient events compared to the 35kV/µs specification on SI8620ED-B-ISR and SI8620BD-B-ISR. Applications with lower common mode transient requirements can utilize the substitute parts. Applications requiring 60kV/µs CMTI performance must use the SI8630ED-ASR or equivalent 3-channel device with matching CMTI specification.

Q: Are all three parts qualified to the same automotive standards?

A: The SI8630ED-ASR is explicitly qualified to AEC-Q100 automotive standards. The SI8620ED-B-ISR and SI8620BD-B-ISR product data confirms active product status and identical manufacturing technology (Capacitive Coupling, General Purpose type). All three parts are manufactured by Skyworks Solutions Inc. and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the inventory status for each part?

A: SI8630ED-ASR has 1054 units in stock. SI8620ED-B-ISR has 18950 units in stock. SI8620BD-B-ISR has 22900 units in stock. The substitute parts provide significantly higher inventory availability.

Q: Are there any compliance or environmental differences between these parts?

A: SI8620ED-B-ISR and SI8620BD-B-ISR both confirm RoHS3 compliance and REACH unaffected status. All three parts share identical Moisture Sensitivity Level (MSL) of 2A (4 Weeks), ECCN classification (EAR99), and HTSUS code (8542.39.0001).
