Engineering Selection Recommendations
Direct Replacement (Microchip Technology): MIC4428YM is the primary direct replacement for MIC4428BM. Both parts maintain identical electrical specifications and 8-SOIC packaging. MIC4428YM is currently active with ROHS3 compliance and higher inventory availability (9162 units).
Extended Temperature Range Alternative: TC4428VOA and TC4428VOA713 support the widest operating temperature range (-40°C ~ 125°C), matching the original MIC4428BM junction temperature capability. These parts are suitable for applications requiring extended thermal performance. TC4428VOA713 is supplied in Tape & Reel format with 15,400 units in stock.
Industrial Temperature Range Alternatives: TC4428EOA and TC4428EOA713 operate across -40°C ~ 85°C with improved rise/fall time characteristics (19ns typical). These are appropriate for industrial applications with moderate temperature requirements.
Commercial Temperature Range Alternatives: TC4428COA, TC4428COA713, MAX4428CSA+, and MAX4428ESA+ operate across 0°C ~ 70°C. These are suitable for commercial-grade applications where extended temperature performance is not required.
Cross-Manufacturer Option: MAX4428ESA+ and MAX4428ESA+T from Analog Devices Inc./Maxim Integrated provide functional equivalence with -40°C ~ 85°C operating range. MAX4428ESA+ has the highest inventory availability (65,550 units). Both maintain identical electrical specifications and 8-SOIC packaging.
All substitute parts are ROHS3 compliant and actively manufactured, ensuring long-term supply chain stability.
Frequently Asked Questions (FAQ)
Q: Can MIC4428YM directly replace MIC4428BM? A: Yes. MIC4428YM maintains identical electrical specifications, package type (8-SOIC), and functional configuration. The primary difference is product status (active vs. discontinued) and RoHS compliance (ROHS3 vs. non-compliant).
Q: What is the difference between TC4428COA and TC4428EOA? A: Both parts are functionally equivalent within the defined parameter set. The primary differences are operating temperature range (TC4428COA: 0°C ~ 70°C; TC4428EOA: -40°C ~ 85°C) and rise/fall time characteristics (TC4428COA: 25ns typical; TC4428EOA: 19ns typical). Select based on application temperature requirements.
Q: Are the 713-suffix variants (TC4428COA713, TC4428EOA713, TC4428VOA713) compatible with non-713 versions? A: Yes. The 713 suffix indicates packaging format (Cut Tape & Digi-Reel or Tape & Reel) and does not affect electrical compatibility. All variants with the same base part number (TC4428COA, TC4428EOA, TC4428VOA) are electrically interchangeable.
Q: Can I use MAX4428ESA+ instead of MIC4428BM? A: Yes. MAX4428ESA+ maintains all critical electrical specifications and 8-SOIC packaging. It is manufactured by Analog Devices Inc./Maxim Integrated and operates across -40°C ~ 85°C. This is a cross-manufacturer substitute suitable for applications not requiring the extended 150°C junction temperature of the original part.
Q: Which substitute part has the best availability? A: MAX4428ESA+ has the highest inventory (65,550 units). For Microchip Technology parts, MIC4428YM (9162 units) and TC4428EOA (24,220 units) offer strong availability.
Q: Does operating temperature range affect substitutability? A: Operating temperature range does not affect electrical substitutability within the defined parameter set. However, application requirements may necessitate selection of parts with specific temperature ratings. Verify application operating conditions before final part selection.
Q: What packaging options are available? A: All substitute parts are supplied in 8-SOIC surface-mount packages. Packaging formats vary (Tube, Cut Tape & Digi-Reel, Tape & Reel) but do not affect electrical compatibility. Select based on procurement and assembly requirements.
