Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMP-381C-TR2G is determined by the following critical parameters:

• Diode Type: PIN - 1 Pair Series Connection configuration must be maintained
• Package / Case: SC-70/SOT-323 form factor compatibility
• Voltage Rating: Peak reverse voltage capability must meet or exceed application requirements
• Current Rating: Maximum current handling must support circuit operation
• Capacitance and Resistance: RF characteristics at specified measurement conditions
• Operating Temperature Range: Must support the thermal environment of the application
• Moisture Sensitivity Level: MSL rating must be compatible with assembly and storage requirements

The identified substitute parts maintain the same diode type, package form factor, and MSL rating. Both substitute components are Active products with current manufacturing availability, addressing the obsolescence status of the original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are Active products with established manufacturing and supply chains, providing reliable alternatives to the Obsolete HSMP-381C-TR2G.

1SV264-TL-E (onsemi): This component is ROHS3 Compliant and available in Cut Tape and Digi-Reel packaging formats. It operates at a maximum junction temperature of 125°C and is suitable for applications where voltage and current requirements do not exceed 50V and 50 mA respectively.

RN779FFHT106 (Rohm Semiconductor): This component is ROHS3 Compliant, AEC-Q101 qualified, and rated for Automotive applications. It maintains the 150°C operating temperature rating of the original part and is available in Tape & Reel packaging. It is suitable for applications where voltage and current requirements do not exceed 50V and 50 mA respectively.

Selection between substitute parts should be based on specific application voltage and current requirements, operating temperature constraints, and any automotive or qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1SV264-TL-E or RN779FFHT106 directly replace the HSMP-381C-TR2G in all applications?

A: Direct replacement depends on application-specific voltage and current requirements. Both substitutes are rated for 50V maximum reverse voltage and 50 mA maximum current, compared to the original part's 100V and 1 A ratings. Applications operating within these lower limits are compatible; applications requiring higher voltage or current ratings require circuit redesign.

Q: What are the key differences in RF characteristics between the main part and substitutes?

A: The HSMP-381C-TR2G exhibits lower capacitance (0.35pF) and lower resistance (3Ohm) compared to both substitutes. The 1SV264-TL-E shows similar capacitance (0.4pF) but higher resistance (4.5Ohm). The RN779FFHT106 exhibits higher capacitance (0.9pF) and higher resistance (7Ohm). These differences may affect RF performance in frequency-dependent applications.

Q: Are both substitute parts available in the same package?

A: Yes, all three parts use the SC-70/SOT-323 package form factor, ensuring physical compatibility on printed circuit boards.

Q: What is the difference in operating temperature ratings?

A: The HSMP-381C-TR2G and RN779FFHT106 are both rated to 150°C junction temperature. The 1SV264-TL-E is rated to 125°C. Applications requiring operation at temperatures above 125°C should use the RN779FFHT106.

Q: Does the RN779FFHT106 have any additional qualifications?

A: Yes, the RN779FFHT106 is AEC-Q101 qualified and designated for Automotive applications, providing additional reliability assurance for automotive and harsh environment applications.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes, all three parts carry MSL 1 (Unlimited) rating, indicating equivalent moisture handling and storage requirements.
