Substitute Part Grouping Explanation

Substitution between B190AE-13 and B190-13-F is based on electrical and mechanical parameter equivalence within the Schottky rectifier diode category. Both parts share identical ratings for reverse voltage (90 V), average rectified current (1 A), forward voltage drop (790 mV @ 1 A), recovery speed classification (Fast Recovery ≤ 500ns), and package form factor (DO-214AC, SMA surface mount). The substitute part maintains compatibility with circuit designs specified for the main part number while offering active product status and improved supply availability.

Key parameters determining substitution eligibility:

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 790 mV @ 1 A
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Technology: Schottky

Engineering Selection Recommendations

The B190-13-F serves as the direct substitute for the obsolete B190AE-13. Selection of B190-13-F is appropriate for new designs and production continuity due to its active product status and identical electrical ratings for reverse voltage, forward voltage, and current capacity. Both parts maintain ROHS3 compliance and identical export classification (EAR99).

The B190-13-F offers an extended operating temperature range (-65°C to 150°C versus -55°C to 150°C), providing additional thermal margin in low-temperature applications. The substitute part exhibits higher reverse leakage current (500 µA versus 200 µA at 90 V) and increased junction capacitance (80 pF versus 27 pF at 4V, 1MHz), which may affect performance in high-frequency switching or low-leakage applications. Circuit designs sensitive to these secondary parameters require evaluation of impact on system performance.

The B190-13-F is supplied in Tape & Reel packaging with Moisture Sensitivity Level 1 (Unlimited), compared to the main part's unspecified packaging format. This packaging format is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can B190-13-F be used as a direct replacement for B190AE-13 in existing designs?

A: Yes. Both parts share identical ratings for reverse voltage (90 V), average rectified current (1 A), forward voltage drop (790 mV @ 1 A), recovery speed, and package form factor (DO-214AC, SMA). Electrical performance in standard rectification applications is equivalent.

Q: What are the differences between B190AE-13 and B190-13-F?

A: The primary differences are product status (obsolete versus active), reverse leakage current (200 µA versus 500 µA at 90 V), junction capacitance (27 pF versus 80 pF at 4V, 1MHz), operating temperature range (-55°C to 150°C versus -65°C to 150°C), and packaging format (unspecified versus Tape & Reel). Electrical ratings for voltage and current are identical.

Q: Are there packaging compatibility considerations?

A: Both parts use the DO-214AC, SMA surface mount package. The B190-13-F is supplied in Tape & Reel format with Moisture Sensitivity Level 1 (Unlimited), suitable for automated assembly. Footprint and soldering requirements are identical.

Q: Which part should be selected for new designs?

A: B190-13-F should be selected for new designs due to its active product status and improved availability. The B190AE-13 is obsolete and not recommended for new development.

Q: Does the higher reverse leakage current of B190-13-F affect circuit performance?

A: The reverse leakage current difference (500 µA versus 200 µA at 90 V) may impact circuits with stringent low-leakage requirements or high-impedance applications. Standard rectification circuits typically tolerate this difference. Circuit-specific evaluation is necessary for applications with leakage-sensitive specifications.

Q: Does the increased junction capacitance of B190-13-F affect high-frequency performance?

A: The junction capacitance difference (80 pF versus 27 pF at 4V, 1MHz) may affect switching speed and high-frequency performance. Applications operating at frequencies where junction capacitance is a limiting factor require evaluation of the impact on switching characteristics and circuit performance.

Q: Are both parts RoHS compliant?

A: Yes. Both B190AE-13 and B190-13-F are ROHS3 compliant and carry identical export classification (EAR99, HTSUS 8541.10.0080).
