Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMP-386C-TR2G is determined by the following critical parameters:

• Diode Type: PIN - 1 Pair Series Connection (functional equivalence)
• Voltage - Peak Reverse (Max): 50V (electrical compatibility requirement)
• Package / Case: SC-70, SOT-323 (mechanical and thermal compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The identified substitute parts meet these core substitution criteria. However, differences exist in maximum current rating, capacitance characteristics, and resistance values. These differences must be evaluated within the context of the specific application circuit to determine functional compatibility.

Engineering Selection Recommendations

1SV264-TL-E (onsemi)

This substitute is an active product with ROHS3 compliance. The maximum current rating is reduced to 50 mA compared to the original 1 A specification. Operating temperature is limited to 125°C versus the original 150°C. Capacitance is higher at 0.4pF, and resistance is increased to 4.5Ohm. Selection of this part requires confirmation that the application circuit operates within the 50 mA current envelope and 125°C thermal limit.

RN779FFHT106 (Rohm Semiconductor)

This substitute is an active product with ROHS3 compliance and AEC-Q101 automotive qualification. Operating temperature matches the original specification at 150°C. Maximum current is reduced to 50 mA. Capacitance is significantly higher at 0.9pF, and resistance is increased to 7Ohm. The automotive grade qualification may provide additional reliability assurance for certain applications. Selection of this part requires confirmation that the application circuit operates within the 50 mA current envelope.

Frequently Asked Questions (FAQ)

Q: Can the HSMP-386C-TR2G be directly replaced with either substitute part?

A: Direct replacement is possible only if the application circuit operates at currents not exceeding 50 mA. Both substitute parts have maximum current ratings of 50 mA, compared to the original 1 A specification. Circuit analysis is required to confirm compatibility.

Q: What are the key differences between the two substitute parts?

A: Both parts share the same 50V voltage rating and SC-70, SOT-323 package. The RN779FFHT106 maintains the 150°C operating temperature of the original part, while the 1SV264-TL-E is limited to 125°C. The RN779FFHT106 has higher capacitance (0.9pF) and resistance (7Ohm) compared to the 1SV264-TL-E (0.4pF and 4.5Ohm respectively).

Q: Are both substitute parts available in the same packaging format?

A: Both parts use the SC-70, SOT-323 package case. The 1SV264-TL-E is supplied in Cut Tape (CT) & Digi-Reel format, while the RN779FFHT106 is supplied in Tape & Reel (TR) format. Both are compatible with standard pick-and-place assembly equipment.

Q: What compliance certifications apply to the substitute parts?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. The RN779FFHT106 carries additional AEC-Q101 automotive qualification, which may be relevant for applications requiring automotive-grade components.

Q: How do the electrical characteristics differ from the original part?

A: The original HSMP-386C-TR2G has lower capacitance (0.2pF) and lower resistance (1.5Ohm) compared to both substitutes. These differences affect high-frequency performance and signal insertion loss. Circuit simulation or testing is necessary to determine if these parameter shifts are acceptable for the specific application.
