Key Parameters

Substitute Part Grouping Explanation

Substitution of the SI8410BB-C-IS is determined by the following critical parameters:

• Isolation Voltage: 2500Vrms minimum
• Number of Channels: Single channel (1 channel)
• Channel Configuration: Unidirectional input/output topology
• Data Rate: 150Mbps minimum
• Common Mode Transient Immunity: 25kV/µs or greater
• Package Type: 8-SOIC surface mount form factor
• Supply Voltage Range: 2.7V ~ 5.5V compatibility
• Operating Temperature Range: -40°C ~ 125°C minimum

The SI8410BB-D-IS qualifies as a direct substitute, sharing identical electrical specifications and package configuration with the main part number. Both variants are manufactured by Skyworks Solutions Inc. using the same SI8410 base product platform with capacitive coupling technology.

Parameter Comparison

Engineering Selection Recommendations

The SI8410BB-D-IS is the direct equivalent substitute for the SI8410BB-C-IS. Both parts share identical electrical performance specifications, package configuration, and thermal operating range. The substitution is valid for applications requiring single-channel digital isolation at 2500Vrms with 150Mbps data rate capability.

Both the main part and substitute are classified as "Not For New Designs" by the manufacturer, indicating end-of-life status. For new product development, alternative digital isolator solutions from current product lines should be evaluated based on the same isolation voltage, channel count, data rate, and package requirements.

The SI8410BB-D-IS maintains the same Moisture Sensitivity Level (MSL 2A) and operating temperature specifications, ensuring compatibility in existing assembly and storage processes.

Frequently Asked Questions (FAQ)

Q: Can SI8410BB-D-IS be used as a direct replacement for SI8410BB-C-IS in existing designs?

A: Yes. The SI8410BB-D-IS is electrically and mechanically identical to the SI8410BB-C-IS. All electrical parameters, timing specifications, supply voltage range, and package dimensions are equivalent. Direct substitution is valid without circuit modification.

Q: What are the key parameters that define substitutability for this digital isolator?

A: Substitution is determined by: isolation voltage rating (2500Vrms), single-channel unidirectional configuration, 150Mbps data rate, 25kV/µs CMTI, 8-SOIC package form factor, 2.7V–5.5V supply compatibility, and -40°C to 125°C operating temperature range.

Q: Are there differences in compliance or certification between SI8410BB-C-IS and SI8410BB-D-IS?

A: The SI8410BB-D-IS carries RoHS3 compliance and REACH unaffected status certifications. Both parts share the same ECCN (EAR99) and HTSUS classification. Verify compliance requirements for your specific application and region.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the part has reached end-of-life. While existing inventory remains available, Skyworks Solutions Inc. does not recommend these parts for new product development. For new designs, evaluate current-generation digital isolator alternatives meeting the same functional requirements.

Q: Are the package dimensions and mounting requirements identical?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pin configuration, footprint, and MSL rating (2A, 4 Weeks). PCB layout and assembly processes require no modification.
