FFF CompatibilityThe pin mapping is identical: Pin 1 connects to Pin 4 when Select is HIGH, and Pin 3 connects to Pin 4 when Select is LOW. The SC-70-6 package mounts on the same land pattern.The physical dimensions of the SC-70-6 package are compatible with the original SC-88 (SC-70-6) footprint.Provides identical 2:1 multiplexing/demultiplexing function with expanded operating voltage and temperature ranges.
AI Summary

NC7SB3257P6X by onsemi: Multiplexer/Demultiplexer 1 x 2:1 SC-88 (SC-70-6).

This active component from Texas Instruments is a highly reliable, industry-standard drop-in replacement. It features an identical pin configuration and functional logic map, while expanding the working voltage range down to 1.65 V and the operating temperature up to 125°C. This makes it an ideal second-source option to replace the obsolete NMOS switch with a robust CMOS equivalent.

  • Highly active lifecycle with excellent long-term availability
  • Wider recommended operating supply voltage range (1.65 V to 5.5 V vs. 4.0 V to 5.5 V)
  • Extended operating temperature range up to 125°C compared to original's 85°C maximum
  • Slightly higher typical on-state resistance (6 Ohms typical vs 3 Ohms typical)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
