Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HSMS-282C-TR2G is determined by the following critical parameters:

• Diode Configuration: Must be 1 pair series connection Schottky technology
• Package Compatibility: Must use SC-70 or SOT-323 surface mount package
• Voltage Rating: Reverse voltage must be equal to or greater than 15V
• Current Capability: Must support the application's current requirements without exceeding rated limits
• Thermal Performance: Operating temperature range must accommodate the application environment
• Moisture Sensitivity: MSL rating must be compatible with assembly and storage conditions

Both substitute parts listed maintain the required diode configuration, package form factor, and voltage/current envelope necessary for direct functional replacement in applications designed for the HSMS-282C-TR2G.

Parameter Comparison

Engineering Selection Recommendations

1PS70SB84,115 (Nexperia USA Inc.)

This substitute maintains identical voltage and diode configuration specifications to the original HSMS-282C-TR2G. The part is active in production with high inventory availability (60,927 pcs). It carries AEC-Q100 automotive qualification and ROHS3 compliance. Current rating of 30mA is suitable for applications where the original 1A maximum is not fully utilized. Maximum junction temperature of 125°C is lower than the original 150°C specification; verify thermal requirements for your application environment.

BAT54SWFILM (STMicroelectronics)

This substitute provides enhanced voltage rating (40V vs. 15V) and higher current capability (300mA vs. 1A maximum), offering design margin for applications with variable load conditions. The part is active in production with substantial inventory (32,200 pcs) and includes ROHS3 compliance. Operating temperature range of -40°C to 150°C matches or exceeds the original specification. Fast recovery characteristics (5 ns reverse recovery time) may provide performance benefits in high-frequency RF applications. The higher voltage rating introduces no compatibility issues for 15V-rated circuit designs.

Both substitutes are active products with established supply chains, ROHS3 compliance, and MSL-1 moisture sensitivity ratings matching the original component.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB84,115 directly replace the HSMS-282C-TR2G in all applications?

A: The 1PS70SB84,115 maintains identical voltage rating (15V) and diode configuration. Direct replacement is suitable for applications where current requirements do not exceed 30mA. If your circuit requires the full 1A capability of the original part, verify actual current draw before substitution. Maximum junction temperature is 125°C versus 150°C for the original; confirm thermal operating conditions are compatible.

Q: What are the advantages of using BAT54SWFILM as a substitute?

A: The BAT54SWFILM offers higher voltage rating (40V) and current capability (300mA), providing design margin for applications with variable specifications. It maintains the same SOT-323 package and includes fast recovery characteristics beneficial for RF applications. The extended operating temperature range (-40°C to 150°C) accommodates wider environmental conditions.

Q: Are both substitutes compatible with the original SOT-323 package footprint?

A: Yes. Both 1PS70SB84,115 and BAT54SWFILM use SC-70/SOT-323 surface mount packaging, ensuring mechanical and electrical compatibility with PCB layouts designed for the HSMS-282C-TR2G.

Q: What compliance certifications apply to the substitute parts?

A: Both substitutes are ROHS3 compliant and REACH unaffected. The 1PS70SB84,115 carries AEC-Q100 automotive qualification. Both maintain MSL-1 (unlimited) moisture sensitivity rating.

Q: How do I determine which substitute is appropriate for my application?

A: Evaluate your circuit's maximum current requirement. If current does not exceed 30mA, the 1PS70SB84,115 provides a direct equivalent. If current requirements approach or exceed 100mA, the BAT54SWFILM is the appropriate choice. Verify thermal operating conditions against the maximum junction temperature specifications of each candidate part.
