Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching parameters relevant to function, electrical performance, and mechanical compatibility. The following parameters are required to be identical or within allowable tolerances for the application:

• Transistor Type
• Current - Collector (Ic) (Max)
• Voltage - Collector Emitter Breakdown (Max)
• Vce Saturation (Max) @ Ib, Ic
• Current - Collector Cutoff (Max)
• DC Current Gain (hFE) (Min) @ Ic, Vce
• Power - Max
• Frequency - Transition
• Operating Temperature
• Mounting Type
• Package / Case
• RoHS Status
• Moisture Sensitivity Level (MSL)
• ECCN
• HTSUS

Parameter Comparison

Engineering Selection Recommendations

Both SS8050-HF and MMSS8050HE3-H-TP are active, RoHS3 compliant, and rated with Moisture Sensitivity Level 1 (Unlimited). Both devices carry the same ECCN and HTSUS classifications, ensuring regulatory compatibility. The MMSS8050HE3-H-TP provides additional qualification as AEC-Q101 Automotive grade, which can be considered in selection when such compliance is required by the application.

Frequently Asked Questions (FAQ)

Q1: What determines if MMSS8050HE3-H-TP is a valid substitute for SS8050-HF?
A1: Validity is established through matching transistor type, electrical ratings (current, voltage, gain), power rating, frequency response, mechanical package, RoHS status, and regulatory classifications.

Q2: Are there differences in the mounting or package?
A2: Both SS8050-HF and MMSS8050HE3-H-TP are supplied in SOT-23-3 compatible surface mount packages, ensuring mechanical compatibility.

Q3: Is automotive qualification required for substitution?
A3: If automotive-grade qualification (AEC-Q101) is mandated, MMSS8050HE3-H-TP meets this requirement; SS8050-HF does not specify automotive grade.

Q4: Are there environmental or compliance considerations in substituting these parts?
A4: Both parts are ROHS3 compliant and have Moisture Sensitivity Level 1 ratings. Both share the same ECCN and HTSUS codes.

Q5: Does regulatory classification affect interchangeability?
A5: Both SS8050-HF and MMSS8050HE3-H-TP are classified as EAR99 for ECCN and have identical HTSUS codes, supporting interchangeable usage from a regulatory perspective.
