FFF CompatibilityBoth devices use the 2-pin SOD-123 footprint with Pin 1 designated as Cathode and Pin 2 as Anode.Matches the identical SOD-123 surface-mount package shape, pitch, and profile.Matches key parameters including 3.9 V nominal Zener voltage, 500 mW power rating, and 5 µA reverse leakage.Both devices share the standard SOD-123 package outline with cathode and anode assignments.Both utilize the industry-standard SMD SOD-123 packaging dimensions.Matches the original 3.9 V nominal voltage, 500 mW power rating, and 50 µA test current.
AI Summary

MMSZ4686T1 by onsemi: Zener Diode 3.9 V 500 mW ±5% Surface Mount SOD-123.

This is a high-confidence direct equivalent that matches the low test current (50 µA) specification of the original onsemi part, ensuring consistent voltage regulation in low-power circuits.

  • Identical pinout and standard SOD-123 surface-mount footprint
  • True low-current Zener diode characterized at the same low test current of 50 µA
  • Provides a wider operating temperature range from -65°C to +150°C

This active part offers an exact functional equivalent with the same low-current test specifications as the obsolete onsemi device.

  • Direct electrical equivalent characterized at the same low test current of 50 µA
  • Identical SOD-123 package and pin configurations
  • Slightly higher maximum forward voltage: 950 mV vs 900 mV @ 10 mA.

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.
