Substitute Part Grouping Explanation

Substitution for the SI8410AB-C-IS is determined by strict alignment of the following critical parameters:

  • Isolation Voltage: 2500Vrms minimum
  • Channel Configuration: Single channel, unidirectional topology
  • Data Rate: 1Mbps or higher
  • Common Mode Transient Immunity: 25kV/µs or greater
  • Package: 8-SOIC form factor with 0.154" (3.90mm) width
  • Supply Voltage Range: 2.7V ~ 5.5V compatibility
  • Operating Temperature Range: -40°C ~ 125°C minimum

The SI8410AB-D-IS is identified as a direct substitute within the same SI8410 base product family. Both parts share identical electrical specifications, isolation ratings, channel configuration, and package specifications. The primary difference is the product status and compliance certifications of the substitute part.

Engineering Selection Recommendations

The SI8410AB-D-IS serves as the direct substitute for the SI8410AB-C-IS based on complete electrical and mechanical parameter equivalence. Both parts are marked "Not For New Designs," reflecting their end-of-life status within the Skyworks Solutions product line.

The SI8410AB-D-IS provides documented RoHS3 compliance and REACH unaffected status, whereas these certifications are not specified for the SI8410AB-C-IS. For applications subject to environmental or regulatory compliance requirements, the SI8410AB-D-IS offers explicit certification documentation.

Selection between these parts should be based on inventory availability, compliance documentation requirements, and existing supply chain relationships. No electrical or mechanical redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can SI8410AB-D-IS replace SI8410AB-C-IS in existing designs?

A: Yes. Both parts are electrically and mechanically identical, sharing the same isolation voltage (2500Vrms), single-channel unidirectional configuration, 1Mbps data rate, 25kV/µs CMTI, and 8-SOIC package. No circuit modifications are required.

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

A: This designation indicates the part has reached end-of-life. Both the SI8410AB-C-IS and SI8410AB-D-IS carry this status, meaning Skyworks Solutions is no longer recommending these parts for new product development. Existing inventory may be available for legacy system support and production continuity.

Q: Are there compliance differences between these parts?

A: The SI8410AB-D-IS explicitly documents RoHS3 compliance and REACH unaffected status. The SI8410AB-C-IS does not specify these certifications. For applications requiring documented environmental compliance, the SI8410AB-D-IS provides explicit certification.

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with surface mount mounting type. PCB layouts and assembly processes require no modification.

Q: What supply voltage range do these parts support?

A: Both parts operate across 2.7V to 5.5V supply voltage range, supporting single-supply and dual-supply configurations within this window.

Q: Are there temperature range limitations?

A: Both parts operate across -40°C to 125°C, covering industrial and extended commercial temperature ranges.
