Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching or exceeding the following key parameters:

• Transistor Type (NPN)
• Collector-Emitter Breakdown Voltage
• Transition Frequency
• Gain
• Maximum Power
• DC Current Gain at defined conditions
• Maximum Collector Current
• Operating Temperature
• Mounting Type
• Package / Case
• Relevant compliance status (RoHS, MSL)
• Product availability status

Substitutes listed—BFP460H6327XTSA1, BFR380L3E6327XTMA1, and MRF448—are grouped due to their categorical alignment (NPN RF BJTs) and parameter specification in the provided data.

Parameter Comparison

Engineering Selection Recommendations

Based strictly on product status and compliance, 2307 is obsolete and RoHS non-compliant. Substitute parts BFP460H6327XTSA1, BFR380L3E6327XTMA1, and MRF448 are all active and RoHS3 compliant. Selection among substitute parts should be conducted with attention to availability, required compliance criteria for the end application, and alignment with specified certifications (RoHS, REACH, ECCN, HTSUS, MSL).

Frequently Asked Questions (FAQ)

Q1: What defines an allowable substitute for 2307?
Allowable substitutes are identified by matching the transistor type (NPN), core electrical characteristics (voltage, current, power, gain), mounting type, and compliance status as specified.

Q2: Are mounting types and package styles equivalent between all listed parts?
Not all substitute models share the same mounting type or package. 2307 and MRF448 are chassis-mount transistors; BFP460H6327XTSA1 and BFR380L3E6327XTMA1 are surface mount with differing packages (SOT-343, SOT-883).

Q3: How does RoHS compliance affect substitute part selection?
2307 is RoHS non-compliant, while all substitutes listed are RoHS3 compliant. For applications requiring RoHS compliance, preference should be given to substitutes.

Q4: Do substitute transistors match the same collector-emitter voltage rating as the 2307?
Voltage ratings vary; MRF448 exceeds the 2307 rating, BFP460H6327XTSA1 and BFR380L3E6327XTMA1 have lower voltage ratings.

Q5: Is it necessary to consider transition frequency and maximum power in substitution?
Transition frequency and maximum power are key substitution criteria. Substitute parts provided cover a range of these specifications. Selection should align with the explicit parameter requirements.

Q6: What is the effect of operating temperature differences among substitutes?
2307 specifies an operating junction temperature of 200°C; substitutes provide lower maximum operating temperatures in supplied data. Verification against application requirements is required based strictly on provided parameter values.

Q7: Is pin-out or device footprint equivalent across substitute models?
Pin-out and mechanical footprint may differ, as indicated by package/case details. Substitute selection must align with the required mounting and package parameters specified.
