Equivalent & Substitute Parts Reference for 2SA2072TLQ

Part Overview

The 2SA2072TLQ from Rohm Semiconductor is a surface mount PNP bipolar junction transistor (BJT), rated for 60 V, 3 A, 180MHz, and 1 W maximum power dissipation. It is supplied in a CPT3 package (TO-252-3, DPAK compatible), and designed for applications requiring high current and voltage handling with PNP polarity in compact SMD layouts. The part is marked as “Not For New Designs,” indicating end-of-life status. When sourcing or designing new assemblies, it is necessary to find suitable alternative models that fulfill the same electrical and mechanical parameters within the transistors, bipolar (BJT) category.

Engineering Selection Recommendations

Substitute part selection for 2SA2072TLQ is guided by current product status. As 2SA2072TLQ is marked "Not For New Designs" and compliance requirements such as RoHS3 and REACH must be met, candidate substitutes should have "Active" product status, identical compliance certifications, and matching MSL ratings. Compatible surface-mount packages, transistor type, and collector/voltage ratings are required for proper form, fit, and function within the same application.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters for BJT substitution in surface mount designs?
A1: Transistor type (PNP), collector current rating, breakdown voltage, package compatibility (TO-252-3/DPAK), and compliance certifications are critical for substitution in surface mount BJT applications.

Q2: Are all recommended substitute parts available in identical packages to 2SA2072TLQ?
A2: All listed substitute parts are available in TO-252-3, DPAK (2 Leads + Tab), SC-63 surface mount packages, matching the mechanical requirements of 2SA2072TLQ.

Q3: Can substitutes with higher collector current ratings be used in place of 2SA2072TLQ?
A3: Substitutes with equal or higher collector current ratings are compatible based on provided electrical parameters, provided other key parameters and package are identical.

Q4: How do compliance certifications impact part selection?
A4: All substitute parts retain RoHS3 and REACH status, ensuring regulatory compliance in environments where substance restrictions are mandated.

Q5: Does product lifecycle status affect substitute selection?
A5: Substitute selection is affected by product status; “Active” or “In Stock” parts are prioritized for designs replacing obsolete or “Not For New Designs” models.
