Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on specific electrical and mechanical parameters. Key parameters include transistor type, collector current (Ic) maximum, collector-emitter breakdown voltage, integrated base and emitter resistors (R1, R2), DC current gain (hFE), transition frequency, maximum power dissipation, mounting type, package/case, and compliance characteristics (MSL, REACH status). These factors must match between the DTA143XUBTL and substitute candidates to ensure direct compatibility for functional and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection should be based on the product status and compliance data provided. DTA143XUBTL is designated "Not For New Designs," while PDTA143XU,115 is marked "Active." Both products maintain a Moisture Sensitivity Level of 1 (Unlimited) and REACH Unaffected status, ensuring compatibility with regulatory and reliability requirements. For ongoing and new product designs, preference should be given to substitute parts that have an "Active" status and meet the same compliance standards.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for substituting DTA143XUBTL?
A1: Substitution is determined strictly by matching transistor type, mounting method, and compliance parameters. Electrical and mechanical features must align to ensure full compatibility.

Q2: Is package compatibility required for substitution?
A2: Yes. The mounting type and package/case are essential to guarantee proper integration into existing PCB layouts and automated assembly processes.

Q3: How does product status affect component selection?
A3: Product status indicates availability for new designs. "Active" parts are preferred for ongoing and future design activities; "Not For New Designs" should be phased out or replaced where feasible.

Q4: What role do compliance parameters play in substitution?
A4: Compliance fields such as Moisture Sensitivity Level and REACH status ensure selected parts meet environmental, safety, and long-term reliability requirements.

Q5: Can PDTA143XU,115 directly replace DTA143XUBTL?
A5: Based strictly on the provided parameters, PDTA143XU,115 meets necessary substitution criteria for product category, type, mounting method, and compliance.
