Substitute Part Grouping Explanation
Substitute parts for the MMBFJ110 are classified into two categories based on electrical and mechanical compatibility:
Direct Substitutes maintain the same voltage rating (25 V), N-Channel configuration, SOT-23-3 package, and surface mount technology. These parts differ in specific drain current characteristics, cutoff voltage, and power dissipation ratings but remain functionally interchangeable within the specified electrical envelope.
Similar Substitutes share the same package, mounting type, and N-Channel configuration but operate at different voltage ratings (30 V) or employ different package variants (3-CPH). These parts are suitable for applications where higher voltage margins or alternative package formats are acceptable.
Key parameters determining substitution eligibility:
- Voltage - Breakdown (V(BR)GSS): 25 V or higher
- FET Type: N-Channel
- Package / Case: SOT-23-3 or equivalent footprint
- Mounting Type: Surface Mount
- RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations
All listed substitute parts maintain Active product status and RoHS3 compliance, meeting regulatory requirements equivalent to the MMBFJ110.
For direct electrical replacement with 25 V rating: MMBFJ310LT1G, MMBFJ310LT3G, MMBFU310LT1G, and CPH3910-TL-E provide 25 V breakdown voltage matching. MMBFJ310 variants offer higher current ratings (60 mA) suitable for applications requiring increased drain current capacity. MMBFU310LT1G provides lower power dissipation (225 mW) for thermally constrained designs.
For automotive-grade applications: SMMBFJ310LT1G and SMMBFJ310LT3G are qualified to AEC-Q101 standard, providing automotive-grade reliability with 25 V rating and SOT-23-3 packaging.
For higher voltage margin applications: MMBF4391LT1G, MMBF4392LT1G, and MMBF4393LT1G operate at 30 V breakdown voltage, offering increased voltage headroom. These parts maintain SOT-23-3 package compatibility and surface mount technology. Selection among these three depends on required drain current and cutoff voltage characteristics.
For packaging format alternatives: CPH3910-TL-E uses 3-CPH package variant while maintaining 25 V rating and SOT-23-3 footprint compatibility.
Frequently Asked Questions (FAQ)
Q: Can MMBFJ310LT1G directly replace MMBFJ110 in existing designs?
A: Yes. Both parts share 25 V breakdown voltage, N-Channel configuration, and SOT-23-3 package. MMBFJ310LT1G provides higher drain current rating (60 mA vs. 10 mA), making it suitable for applications requiring increased current capacity within the same voltage envelope.
Q: What is the difference between MMBFJ310LT1G and MMBFJ310LT3G?
A: Both parts are electrically identical with 25 V rating, 60 mA current rating, and SOT-23-3 package. The difference is packaging format: LT1G uses Cut Tape & Digi-Reel®, while LT3G uses Tape & Reel (
