Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent selection for MMBT2907A-TP-HF is determined by strictly matching the fundamental electrical and mechanical attributes:

• Transistor Type (PNP)
• Breakdown Voltage (≥ 60V)
• Collector Current (≥ 600mA)
• DC Current Gain (≥ 100 @ specified conditions)
• Vce Saturation (≤ 1.6V @ specified Ib & Ic)
• Frequency (≥ 200MHz)
• Power Dissipation (≥ 250mW)
• Package / Case (SOT-23 or compatible)
• Mounting (Surface Mount)
• Operating Temperature Range (-55°C ~ 150°C)
• Compliance and Product Status

Only components matching these parameters are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Where the product status of the substitution candidate is Active and compliance badges such as ROHS3 and REACH Unaffected are present, the candidate is suitable for use as a direct replacement under defined parameters. Obsolete parts such as MMBT2907A-G should only be considered for existing designs with managed inventory due to supply limitations. Product compliance, such as RoHS and REACH status, is suitable for all listed active alternatives.

Frequently Asked Questions (FAQ)

Q: What criteria were used to select substitute BJTs for MMBT2907A-TP-HF?
A: Only parts meeting the same PNP BJT type, minimum breakdown voltage, maximum collector current, minimum DC current gain, saturation voltage, cutoff current, frequency, power dissipation, surface mount package/case compatibility, and full operating temperature range were considered.

Q: Are all substitutes guaranteed to fit the same PCB footprint as the original SOT-23?
A: All listed substitutes specify SOT-23 or compatible surface-mount formats, matching provided package/case data.

Q: Should obsolete substitutes such as MMBT2907A-G be used for new designs?
A: Obsolete status denotes limited future availability and is generally not preferred for new designs where longevity and supply assurance are required.

Q: How do compliance parameters such as RoHS and REACH affect substitute selection?
A: All active substitutes meet RoHS3 and REACH Unaffected criteria, permitting use in environments where these compliance standards are mandated.

Q: Is there any difference in electrical performance between substitutes in the provided table?
A: All substitutes meet the specified electrical performance for voltage, current, gain, and frequency based on the provided parameters. Any variation remains strictly within the allowable range defined by the original part's parameters.

Q: Does package naming (SOT-23, SOT-23-3, TO-236-3) affect interchangeability?
A: For this category and group as listed, TO-236-3, SC-59, and SOT-23-3 are considered interchangeable based on supplied data. Always confirm mechanical compatibility to the provided package specification.
