Substitute Part Grouping Explanation
Substitution of the BAP65-05W,115 is determined by the following critical parameters:
- Diode configuration: 1-pair common cathode PIN diode topology
- Package compatibility: SC-70 / SOT-323 form factor
- Voltage rating: Minimum 30V peak reverse voltage
- Power dissipation capability: Minimum 240 mW
- Frequency performance: Operation at 100 MHz and above
- Temperature range: Support for -65°C to 150°C operating window
- Compliance standards: ROHS3 compliance and REACH unaffected status
The DAN235UT106 from Rohm Semiconductor meets these substitution criteria as an active product with compatible electrical characteristics and identical package specifications.

Engineering Selection Recommendations
The DAN235UT106 is the manufacturer-recommended substitute for the obsolete BAP65-05W,115. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The substitute maintains identical package specifications (SC-70 / SOT-323) and common cathode PIN diode topology, enabling direct PCB-level replacement.
Selection of the DAN235UT106 is appropriate for applications where the lower power dissipation rating (150 mW versus 240 mW) and reduced maximum operating temperature (125°C versus 150°C) are acceptable within the system design constraints. The higher peak reverse voltage rating (35V versus 30V) provides additional design margin.
Frequently Asked Questions (FAQ)
Q: Can the DAN235UT106 be used as a direct pin-for-pin replacement?
A: Yes. Both the BAP65-05W,115 and DAN235UT106 use the SC-70 (SOT-323) package with identical pinout for 1-pair common cathode PIN diode configurations.
Q: What are the key differences between these parts?
A: The primary differences are product status (obsolete versus active), power dissipation rating (240 mW versus 150 mW), maximum operating temperature (150°C versus 125°C), and measured capacitance and resistance values at different bias conditions.
Q: Are there thermal considerations when substituting?
A: Yes. The DAN235UT106 has a maximum power dissipation of 150 mW compared to 240 mW for the BAP65-05W,115. Verify that your application's thermal requirements do not exceed this lower rating.
Q: Is the DAN235UT106 suitable for high-temperature applications?
A: The DAN235UT106 is rated to 125°C maximum junction temperature, which is lower than the BAP65-05W,115 rating of 150°C. Applications requiring operation above 125°C require evaluation of alternative parts.
Q: Do both parts meet current compliance standards?
A: Yes. Both the BAP65-05W,115 and DAN235UT106 are ROHS3 compliant and REACH unaffected.
Q: What is the availability status of the substitute?
A: The DAN235UT106 is an active product with 83,200 pieces in stock, ensuring production continuity for the obsolete BAP65-05W,115.
