SI8630BD-AS Equivalent & Substitute Parts

Part Overview

The SI8630BD-AS is an automotive-grade general purpose digital isolator manufactured by Skyworks Solutions Inc. This device provides 5000Vrms isolation across 3 unidirectional channels with a maximum data rate of 150Mbps and operates across the automotive temperature range of -40°C to 125°C. The SI8630BD-AS is classified as Active product status and is qualified to AEC-Q100 automotive standards.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained while meeting application requirements. The SI8630BD-AS may require alternatives due to inventory availability, supply chain considerations, or application-specific channel count requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI8630BD-AS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Skyworks Solutions Inc.
• Voltage - Isolation: 5000Vrms
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Voltage - Supply: 2.5V ~ 5.5V
• Operating Temperature: -40°C ~ 125°C
• Data Rate: 150Mbps
• Technology: Capacitive Coupling
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Number of Channels: May differ based on application requirements
• Common Mode Transient Immunity (Min): May be lower than the main part
• Propagation Delay and Pulse Width Distortion: Must remain within specified maximums

The SI8610BD-B-IS qualifies as a parametric equivalent because it maintains all mandatory matching parameters while operating with a reduced channel count (1 channel versus 3 channels) and lower common mode transient immunity (35kV/µs versus 60kV/µs).

Parameter Comparison

Engineering Selection Recommendations

SI8630BD-AS Selection Criteria:

• Applications requiring 3 isolated channels in a single package
• Systems requiring 60kV/µs common mode transient immunity
• Designs with automotive qualification mandate (AEC-Q100)
• Applications where all three isolation channels are utilized

SI8610BD-B-IS Selection Criteria:

• Applications requiring single-channel isolation only
• Systems where 35kV/µs common mode transient immunity is sufficient
• Designs where automotive qualification is not mandatory
• Supply chain scenarios where SI8610BD-B-IS availability exceeds SI8630BD-AS

Both devices maintain identical electrical performance in data rate, propagation delay, pulse width distortion, and rise/fall time characteristics. Package footprint and mounting type are identical, enabling direct physical substitution when channel count and common mode transient immunity requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can SI8610BD-B-IS replace SI8630BD-AS in all applications?

A: No. SI8610BD-B-IS provides only 1 isolated channel compared to SI8630BD-AS's 3 channels. Substitution is valid only for applications requiring single-channel isolation. Additionally, SI8610BD-B-IS specifies 35kV/µs common mode transient immunity versus SI8630BD-AS's 60kV/µs; applications sensitive to common mode transient events must confirm SI8610BD-B-IS performance is acceptable.

Q: Are the packages physically identical?

A: Yes. Both SI8630BD-AS and SI8610BD-B-IS use 16-SOIC (0.295", 7.50mm Width) surface mount packages. PCB footprints are identical, allowing direct physical substitution without layout modifications.

Q: What is the difference in isolation voltage between these parts?

A: Both devices provide 5000Vrms isolation voltage. Isolation voltage is identical and does not differentiate these parts.

Q: Does SI8610BD-B-IS meet automotive qualification standards?

A: SI8610BD-B-IS product status is Active and manufactured by Skyworks Solutions Inc. with identical technology and electrical specifications to SI8630BD-AS. However, automotive qualification status (AEC-Q100) is not specified for SI8610BD-B-IS. Applications with mandatory automotive qualification requirements must confirm compliance documentation before substitution.

Q: Are the data rates equivalent?

A: Yes. Both SI8630BD-AS and SI8610BD-B-IS operate at 150Mbps maximum data rate. Data rate performance is identical between these devices.

Q: What is the primary limitation of SI8610BD-B-IS as a substitute?

A: The primary limitation is channel count. SI8610BD-B-IS provides 1 isolated channel versus SI8630BD-AS's 3 channels. Applications utilizing multiple isolation channels cannot use SI8610BD-B-IS without additional components or alternative architecture.
