Engineering Selection Recommendations

The 2SD2143TL is currently listed as “Not For New Designs,” while MJD44E3T4G, NJVMJD44E3T4G, and NJVMJD6039T4G are all “Active.” All substitute parts are ROHS3 Compliant and REACH Unaffected. They maintain MSL 1 (Unlimited) status. Selection from these alternatives can be made solely on the basis of product availability and environmental compliance status provided.

Frequently Asked Questions (FAQ)

Q1: What are the critical criteria for substituting the 2SD2143TL in an application?
A1: The substitute transistor must be NPN Darlington type, support surface mount (TO-252-3, DPAK, SC-63), have equal or higher voltage and current ratings, fulfill ROHS3 and REACH compliance, and match or exceed the operating temperature range.

Q2: Are the listed substitutes pin-compatible and physically compatible?
A2: All listed substitutes use the TO-252-3, DPAK (2 Leads + Tab), SC-63 package, matching the 2SD2143TL for mechanical and PCB compatibility.

Q3: Do substitutes have the same environmental compliance as the original part?
A3: Each substitute is ROHS3 Compliant, has MSL 1 (Unlimited) moisture sensitivity, and REACH Unaffected status.

Q4: How does the power rating or current gain of substitute devices affect selection?
A4: Devices are listed only if their key electrical ratings match or exceed those of the 2SD2143TL according to the provided data, ensuring suitability for equivalent electronic designs.

Q5: Can any of these substitutes be used in “New Design” applications?
A5: The substitute parts are each designated as “Active,” allowing their use in both existing and new design configurations according to the product status provided.
