2SA2154MFVGR,L3F Equivalent & Substitute Parts

Part Overview

The 2SA2154MFVGR,L3F is a PNP bipolar junction transistor manufactured by Toshiba Semiconductor and Storage. This surface mount device operates at 50V collector-emitter breakdown voltage with a maximum collector current of 150 mA and is designed for general-purpose switching and amplification applications. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within specified parameter ranges.

Engineering Selection Recommendations

2SA2029T2LR (Rohm Semiconductor) provides direct electrical equivalence to the 2SA2154MFVGR,L3F with identical maximum collector current (150 mA) and power dissipation (150 mW). Both devices share the SOT-723 package and maintain full RoHS3 compliance. The 2SA2029T2LR operates at higher transition frequency (140 MHz versus 80 MHz), which does not restrict its use in applications designed for the original part. This substitute is available in Cut Tape and Digi-Reel packaging with 120,300 units in stock.

2SA2029M3T5G (onsemi) operates within the 50V voltage specification and maintains SOT-723 package compatibility with full RoHS3 compliance. The maximum collector current is reduced to 100 mA, which limits its application to circuits requiring 100 mA or less. The higher transition frequency (140 MHz) and increased power rating (265 mW) provide additional performance margin. This substitute is available in Tape & Reel packaging with 62,080 units in stock.

Both substitute parts maintain active product status and unlimited moisture sensitivity rating, ensuring long-term availability and handling consistency with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 2SA2029M3T5G replace the 2SA2154MFVGR,L3F in all applications?

A: The 2SA2029M3T5G is suitable for applications requiring 100 mA or less collector current. If the circuit design requires the full 150 mA capability of the original part, this substitute is not appropriate. Verify circuit current requirements before selection.

Q: What is the primary difference between the two substitute parts?

A: The 2SA2029T2LR maintains the 150 mA collector current rating of the original part, while the 2SA2029M3T5G is rated for 100 mA maximum. Both operate at 50V and use the SOT-723 package. The 2SA2029T2LR is the direct electrical equivalent.

Q: Are the substitute parts available in the same packaging as the original?

A: The 2SA2029T2LR is supplied in Cut Tape and Digi-Reel packaging. The 2SA2029M3T5G is supplied in Tape & Reel packaging. Both are surface mount devices in SOT-723 package form factor, compatible with standard pick-and-place assembly equipment.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both substitute parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Q: Can I use a substitute part with higher transition frequency?

A: Yes. Both substitute parts operate at 140 MHz transition frequency, which exceeds the original part's 80 MHz specification. Higher frequency capability does not restrict use in applications designed for lower frequency operation.

Q: What inventory levels are available for each substitute?

A: The 2SA2029T2LR has 120,300 units in stock. The 2SA2029M3T5G has 62,080 units in stock. Both are available as new original components.
