Parameter Comparison

Engineering Selection Recommendations

B5817X2-TP is the primary substitute for B5817X-TP. Both parts are manufactured by Micro Commercial Co with identical electrical ratings and package specifications. The B5817X2-TP is active in production status, ensuring long-term availability. Forward voltage is elevated by 100 mV, and reverse leakage current is reduced to 30 µA, representing improved device characteristics. This part is suitable for direct replacement in applications where the original B5817X-TP was specified.

PMEG2010AEB,115 is an alternative substitute manufactured by Nexperia USA Inc. This part maintains identical voltage and current ratings with the same SOD-523 package. Forward voltage is 620 mV, and reverse leakage current is 1.5 mA. The operating temperature maximum extends to 150°C, providing enhanced thermal performance. Capacitance is reduced to 25 pF, which may benefit high-frequency applications. This part is active in production with higher inventory availability. Selection between B5817X2-TP and PMEG2010AEB,115 depends on application-specific requirements for forward voltage drop, leakage current, and thermal operating range.

Both substitute parts maintain full ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original B5817X-TP specification.

Frequently Asked Questions (FAQ)

Q: Can B5817X2-TP directly replace B5817X-TP in existing designs?

A: Yes. B5817X2-TP maintains identical voltage ratings (20V), current ratings (1A), package type (SOD-523), and mounting configuration (surface mount). The forward voltage increase of 100 mV and reduced reverse leakage represent improved performance characteristics. No circuit modifications are required.

Q: What is the difference between B5817X2-TP and PMEG2010AEB,115?

A: Both parts meet the core electrical specifications of 20V, 1A, and SOD-523 packaging. B5817X2-TP is from Micro Commercial Co with forward voltage of 600 mV and reverse leakage of 30 µA. PMEG2010AEB,115 is from Nexperia USA Inc. with forward voltage of 620 mV, reverse leakage of 1.5 mA, and extended operating temperature to 150°C. Selection depends on application sensitivity to forward voltage drop and leakage current characteristics.

Q: Are both substitute parts available in the same packaging format?

A: B5817X2-TP is supplied in Tape & Reel (TR) packaging. PMEG2010AEB,115 is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount components in SOD-523 package format, suitable for automated assembly processes.

Q: Do the substitute parts meet the same compliance standards as B5817X-TP?

A: Yes. Both B5817X2-TP and PMEG2010AEB,115 are ROHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity rating, and are REACH unaffected. Regulatory and environmental compliance is maintained across all three parts.

Q: Which substitute part should be selected for high-temperature applications?

A: PMEG2010AEB,115 supports operating junction temperatures up to 150°C, compared to 125°C for both B5817X-TP and B5817X2-TP. For applications requiring extended thermal performance, PMEG2010AEB,115 is the appropriate selection.

Q: How does reverse leakage current differ among the three parts?

A: B5817X-TP specifies 100 µA @ 20V. B5817X2-TP reduces this to 30 µA @ 20V. PMEG2010AEB,115 specifies 1.5 mA @ 20V. Applications sensitive to leakage current should prioritize B5817X2-TP for lowest leakage performance.

Q: Are there any circuit design considerations when switching between these parts?

A: Forward voltage variations (500 mV to 620 mV) may affect voltage drop calculations in power supply circuits. Reverse leakage differences (30 µA to 1.5 mA) impact standby current consumption. Capacitance variation (25 pF to 120 pF) influences high-frequency switching behavior. Circuit performance should be evaluated within application-specific operating conditions.
