HSMP-389C-TR2G Equivalent & Substitute Parts
Part Overview
The HSMP-389C-TR2G is an RF Diode PIN manufactured by Broadcom Limited, configured as a 1 Pair Series Connection with a peak reverse voltage rating of 100V and maximum current of 1A. This component is packaged in SC-70/SOT-323 form factor. The part is currently listed as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation
Substitution eligibility for the HSMP-389C-TR2G is determined by the following criteria:
Mandatory Parameters:
- Diode Type: PIN - 1 Pair Series Connection
- Package / Case: SC-70, SOT-323
- Voltage - Peak Reverse (Max): Must meet or exceed 100V requirement
- Current - Max: Must meet or exceed 1A requirement
Electrical Compatibility Considerations: The substitute parts identified operate at reduced voltage ratings (50V maximum) compared to the original specification (100V). While the package and diode configuration remain consistent, applications requiring the full 100V rating cannot use these substitutes. The substitute parts are suitable only for circuits where the actual operating voltage does not exceed 50V.

Frequently Asked Questions (FAQ)
Q: Can these substitute parts directly replace the HSMP-389C-TR2G in all applications?
A: No. The substitute parts operate at 50V maximum reverse voltage compared to the original 100V specification. Direct substitution is only possible in circuits where the actual operating voltage does not exceed 50V. Applications requiring the full 100V rating cannot use these substitutes.
Q: What is the primary difference between RN779FFHT106 and RN779FT106?
A: Both parts have identical electrical specifications and operating temperature ratings. RN779FFHT106 carries automotive grade qualification (AEC-Q101), while RN779FT106 does not. Selection depends on whether automotive qualification is required for the application.
Q: Why does the 1SV264-TL-E have a lower operating temperature rating?
A: The 1SV264-TL-E is rated to 125°C junction temperature, compared to 150°C for the original part and the Rohm alternatives. Applications operating near thermal limits may require the higher temperature-rated options.
Q: Are all substitute parts available in the same package?
A: Yes. All substitute parts use SC-70/SOT-323 packaging, maintaining physical and electrical interface compatibility at the board level.
Q: What compliance certifications apply to these substitute parts?
A: All substitute parts are ROHS3 compliant and REACH unaffected. RN779FFHT106 additionally carries AEC-Q101 automotive qualification.
