Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SA1807TLP transistor are determined strictly by matching the following key parameters within the Transistors, Bipolar (BJT) category: transistor type (PNP), maximum collector current (Ic), package type (TO-252-3, DPAK/SC-63), mounting method (surface mount), compliance standards (RoHS3, MSL 1, REACH), and other fundamental electrical properties such as maximum collector-emitter voltage, saturation voltage, current gain, power dissipation, and transition frequency. The parts must have matching or compatible package styles to ensure mechanical fit and compliance requirements for regulatory use.

Parameter Comparison

Engineering Selection Recommendations

The main part number 2SA1807TLP is currently classified as obsolete, whereas the substitute MJD5731T4G is identified as active. Both transistor models are documented as compliant with ROHS3 and REACH standards, and both maintain an MSL rating of 1 (Unlimited). Selection of the substitute part is supported by matching package compatibility, mounting style, and compliance with required environmental and regulatory certifications.

Frequently Asked Questions (FAQ)

Q1: Which key parameters are essential for evaluating substitute bipolar (BJT) transistors for 2SA1807TLP?
A1: The essential substitution criteria include transistor type (PNP), maximum collector current, mounting method, package/case style, power dissipation, compliance status, and maximum rated temperature.

Q2: Is MJD5731T4G mechanically compatible with 2SA1807TLP for board-level replacement?
A2: Both transistors are specified in the TO-252-3, DPAK (2 Leads + Tab), SC-63 package for surface-mount installation, confirming mechanical compatibility.

Q3: Are environmental compliance requirements met by the identified substitute?
A3: Both 2SA1807TLP and MJD5731T4G are confirmed ROHS3 compliant and REACH unaffected, with MSL 1 (Unlimited).

Q4: What is the status of the substitute part compared to the main part?
A4: 2SA1807TLP is obsolete, while MJD5731T4G is active, directly supporting continued application requirements.

Q5: Is there any difference in electrical performance that must be considered when substituting?
A5: The substitute part features a lower voltage collector-emitter breakdown (350 V vs. 600 V), lower transition frequency, and different current gain. These must match the application requirements as per the supplied parameters.
