Q: Can I use a substitute part with higher current rating than the original?

A: Yes, substitute parts with higher current ratings (16 A, 20 A) can be used in applications designed for the original part. Higher current rating provides additional design margin and does not create incompatibility. The device will operate within its specified parameters at the application's actual current draw.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current varies among substitutes from 3.5 µA to 1 mA @ 100 V. Lower leakage current reduces standby power consumption and heat generation. STPS10H100CG-TR (3.5 µA) and CSHDD16-100C TR13 PBFREE (50 µA) offer significantly lower leakage compared to the main part (1 mA). Selection depends on application sensitivity to leakage current.

Q: Are there temperature range considerations for substitute selection?

A: Operating temperature ranges vary among substitutes. CSHDD16-100C TR13 PBFREE extends to 175°C maximum. STPS10H100CG-TR reaches 175°C maximum. VB40100C-E3/4W operates to 150°C. MBRB10100CT and MBRS20100CTH match the main part at 150°C maximum. Selection depends on application thermal environment requirements.

Q: Is REACH compliance status important for part selection?

A: REACH status indicates regulatory substance restrictions. Most substitutes show REACH Unaffected status. MBRB20100CT and MBRB10100CT show REACH Affected status. For applications subject to REACH regulations, substitutes with REACH Unaffected status may be preferred, though all parts are compliant.
