BAS16XV2T1 Equivalent & Substitute Parts

Part Overview

The BAS16XV2T1 is a general-purpose switching diode manufactured by onsemi, rated for 200mA current capacity and 75V reverse voltage in a SOD-523 surface mount package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Equivalent parts maintain functional compatibility within specified electrical and mechanical parameters, while substitute parts offer similar performance characteristics with potential parameter variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS16XV2T1 is determined by compatibility across the following critical parameters:

Package Compatibility: All substitute parts must utilize the SOD-523 surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Current Rating: The main part is rated for 200mA average rectified current. Substitute parts must meet or exceed this current capacity to maintain circuit functionality.

Voltage Rating: The BAS16XV2T1 operates at a maximum reverse voltage of 75V. Substitute parts with equal or higher voltage ratings (100V or greater) provide direct compatibility and enhanced margin.

Technology Classification: The main part is a general-purpose switching diode. Substitute parts classified as standard technology diodes or Schottky diodes with appropriate voltage and current ratings are functionally compatible.

Compliance Status: Active product status and RoHS3 compliance are preferred for new designs and long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): BAS16XV2T1G is the primary equivalent for BAS16XV2T1 replacement. Both parts share the same base product number (BAS16), identical current rating (200mA), and SOD-523 package. BAS16XV2T1G provides enhanced voltage rating (100V versus 75V), improved reverse leakage characteristics (1µA @ 100V), and active product status with ROHS3 compliance. This part is recommended for all new designs and production transitions from the obsolete BAS16XV2T1.

Alternative Equivalent: 1SS400 RKG from Taiwan Semiconductor Corporation maintains the 200mA current rating and 100V voltage specification in SOD-523 packaging. This part offers active status and ROHS3 compliance with improved reverse recovery time (4ns) and lower reverse leakage (100nA @ 80V). Selection of this part is appropriate when onsemi supply is constrained or when multi-source qualification is required.

Current-Limited Substitute: BAS70KFILM from STMicroelectronics is a Schottky technology diode with reduced current capacity (70mA) and voltage rating (70V). This part is suitable only for applications where the circuit current requirement does not exceed 70mA and operating voltage remains below 70V. The Schottky technology provides lower forward voltage drop (1V @ 15mA) compared to standard diodes, which may be advantageous in low-voltage switching applications. This part is not recommended as a direct replacement for 200mA applications.

Frequently Asked Questions (FAQ)

Q: Can BAS16XV2T1G directly replace BAS16XV2T1 in existing designs?

A: Yes. BAS16XV2T1G is a direct equivalent with identical current rating (200mA), compatible voltage rating (100V exceeds the original 75V specification), and identical SOD-523 package. No PCB layout modifications are required. The part is pin-compatible and functionally interchangeable.

Q: What is the primary reason for substituting BAS16XV2T1?

A: BAS16XV2T1 is classified as obsolete. BAS16XV2T1G provides active product status, ensuring long-term availability and supply chain continuity. Additionally, BAS16XV2T1G is ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Is 1SS400 RKG suitable for all BAS16XV2T1 applications?

A: 1SS400 RKG is functionally compatible for applications requiring 200mA current and up to 100V reverse voltage. The part maintains SOD-523 packaging and active product status. Selection depends on supply availability and multi-source qualification requirements. Verify manufacturer availability and lead times for your specific procurement timeline.

Q: Why is BAS70KFILM not recommended as a direct replacement?

A: BAS70KFILM has a maximum current rating of 70mA, which is significantly lower than the BAS16XV2T1 specification of 200mA. This part is suitable only for applications with reduced current requirements. Additionally, the 70V voltage rating is lower than the original 75V specification. Use BAS70KFILM only when circuit analysis confirms current demand does not exceed 70mA.

Q: Are all substitute parts available in the same packaging?

A: Yes. BAS16XV2T1G, 1SS400 RKG, and BAS70KFILM are all supplied in SOD-523 surface mount packages. No package conversion or assembly process modifications are necessary for any of these substitutes.

Q: What compliance certifications apply to the substitute parts?

A: BAS16XV2T1G, 1SS400 RKG, and BAS70KFILM are all ROHS3 compliant and REACH unaffected. All parts carry EAR99 ECCN classification and 8541.10.0070 HTSUS code. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
