Engineering Selection Recommendations
Primary Substitute: KBP310G (Diotec Semiconductor)
The KBP310G is the direct parametric equivalent for the obsolete KBP307G C2. Selection of this substitute is based on the following engineering factors:
- Product Status: The KBP310G maintains active production status, ensuring long-term availability and supply chain continuity.
- Electrical Equivalence: All critical electrical parameters—voltage rating, current rating, and forward voltage characteristics—are identical to the original part.
- Mechanical Compatibility: The 4-SIP KBP package and through-hole mounting configuration provide direct board-level compatibility without circuit redesign.
- Reverse Leakage Performance: The KBP310G exhibits lower reverse leakage current (5 µA versus 10 µA), representing improved device characteristics within the same specification class.
- Operating Temperature: The KBP310G operating range (-50°C to 150°C) encompasses the majority of the original part's range, with compatibility confirmed for standard industrial applications.
- Compliance Status: The KBP310G is ROHS3 compliant, supporting modern manufacturing and environmental regulatory requirements.
Frequently Asked Questions (FAQ)
Q: Can the KBP310G be used as a direct replacement for the KBP307G C2 without circuit modification?
A: Yes. The KBP310G is electrically and mechanically equivalent to the KBP307G C2 across all specified parameters. Direct substitution is supported without circuit redesign or board layout changes.
Q: What is the significance of the lower reverse leakage current in the KBP310G?
A: The KBP310G exhibits 5 µA reverse leakage at 1000 V compared to 10 µA in the KBP307G C2. This represents improved device performance and does not affect substitution compatibility. Lower leakage current reduces power dissipation in standby conditions.
Q: Are there temperature range differences between these parts?
A: The KBP307G C2 operates from -55°C to 150°C, while the KBP310G operates from -50°C to 150°C. For applications requiring operation below -50°C, the original part specification must be retained. For standard industrial temperature ranges, the KBP310G is fully compatible.
Q: Is the KBP package form factor identical between both parts?
A: Yes. Both the KBP307G C2 and KBP310G use the 4-SIP KBP package with through-hole mounting. Pin configuration, spacing, and board footprint are identical.
Q: What compliance certifications apply to the KBP310G?
A: The KBP310G is ROHS3 compliant, supporting modern manufacturing standards and environmental regulations. The original KBP307G C2 was also ROHS3 compliant, ensuring regulatory continuity.
Q: Why is the KBP307G C2 classified as obsolete?
A: Obsolescence reflects the manufacturer's discontinuation of this part number. The KBP310G from Diotec Semiconductor provides equivalent functionality and is actively manufactured, making it the appropriate long-term solution for new designs and legacy system maintenance.
