2SC4116-GR,LF Equivalent & Substitute Parts

Part Overview

The 2SC4116-GR,LF is an NPN bipolar junction transistor manufactured by Toshiba Semiconductor and Storage. This surface mount device is rated for 50 V collector-emitter breakdown voltage with a maximum collector current of 150 mA and 100 mW power dissipation. The part operates at a transition frequency of 80 MHz and is housed in an SC-70 (SOT-323) package. The device is currently in active production status and carries ROHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for components with enhanced electrical characteristics. Substitute parts must maintain compatibility across critical electrical parameters including voltage ratings, current ratings, and package form factors.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The 2PC4081Q,115 and 2PC4081R,135 manufactured by Nexperia USA Inc. are the primary direct substitutes. Both parts maintain the 150 mA collector current and 50 V breakdown voltage specifications. These devices offer enhanced power dissipation (200 mW versus 100 mW) and higher transition frequency (100 MHz versus 80 MHz). Both parts carry AEC-Q101 automotive qualification and are actively produced. The 2PC4081Q,115 and 2PC4081R,135 differ only in DC current gain specifications (120 and 180 respectively at 1 mA, 6 V).

For Applications Requiring Extended Temperature Range:

The 2PC4081Q,115 and 2PC4081R,135 support operating temperatures to 150°C, compared to 125°C for the 2SC4116-GR,LF. These parts are suitable for applications requiring thermal margin beyond the original specification.

For Legacy Design Compatibility:

The 2SC4081T106Q, 2SC4081T106R, and 2SC4081T106S manufactured by Rohm Semiconductor maintain full electrical equivalence with 150 mA current rating and 50 V voltage rating. However, these parts carry "Not For New Designs" status. Use of these parts is limited to existing production lines or legacy system maintenance.

For Reduced Current Applications (100 mA Maximum):

The BC847AW RFG, BC847BW RFG, BC847CW RFG, and BC850AW RFG manufactured by Taiwan Semiconductor Corporation are suitable only for applications where collector current does not exceed 100 mA. These parts operate at 45 V breakdown voltage, which is 5 V below the 2SC4116-GR,LF specification. All four variants are actively produced and support operating temperatures to 150°C.

For Reduced Frequency Applications (60 MHz Maximum):

The 2SC6026CT-GR,L3F manufactured by Toshiba is suitable only for applications where transition frequency requirements do not exceed 60 MHz. This part is limited to 100 mA collector current and uses a different package (SC-101/SOT-883) incompatible with SC-70 footprints.

Frequently Asked Questions (FAQ)

Q: Can the 2PC4081Q,115 be used as a direct replacement for the 2SC4116-GR,LF?

A: Yes. The 2PC4081Q,115 meets or exceeds all critical electrical parameters: 150 mA collector current, 50 V breakdown voltage, SC-70 package compatibility, and surface mount configuration. The part offers superior power dissipation (200 mW) and transition frequency (100 MHz). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between 2PC4081Q,115 and 2PC4081R,135?

A: Both parts are electrically equivalent with identical voltage, current, and package specifications. The difference lies in DC current gain: 2PC4081Q,115 specifies 120 hFE minimum at 1 mA, 6 V, while 2PC4081R,135 specifies 180 hFE minimum at the same conditions. Selection depends on circuit gain requirements.

Q: Why are the 2SC4081T106 variants marked "Not For New Designs"?

A: Parts with "Not For New Designs" status indicate that the manufacturer has discontinued active development and recommends alternative parts for new applications. These parts remain available for existing production support but should not be selected for new circuit designs.

Q: Can BC850AW RFG replace the 2SC4116-GR,LF in all applications?

A: No. The BC850AW RFG has reduced electrical ratings: 100 mA maximum collector current (versus 150 mA) and 45 V breakdown voltage (versus 50 V). This part is suitable only for applications where both current and voltage requirements are within these reduced limits.

Q: Is the 2SC6026CT-GR,L3F compatible with existing 2SC4116-GR,LF PCB layouts?

A: No. The 2SC6026CT-GR,L3F uses SC-101 (SOT-883) package, which is physically incompatible with SC-70 (SOT-323) footprints. Additionally, this part is limited to 100 mA collector current and 60 MHz transition frequency, making it unsuitable for applications requiring the full 150 mA and 80 MHz specifications.

Q: What compliance certifications apply to substitute parts?

A: All listed substitute parts carry ROHS3 compliance. The 2PC4081Q,115 and 2PC4081R,135 additionally carry AEC-Q101 automotive qualification. All parts maintain MSL 1 (unlimited) moisture sensitivity level. Specific REACH status varies by manufacturer; refer to individual part datasheets for REACH compliance details.

Q: Are there package format alternatives to SC-70?

A: The substitute parts listed maintain SC-70 (SOT-323) package compatibility with the 2SC4116-GR,LF. The 2SC6026CT-GR,L3F uses SC-101 (SOT-883) package and is not compatible with existing SC-70 layouts. No other package variants are included in this equivalency list.

Q: What is the inventory status of substitute parts?

A: 2PC4081Q,115 has 3,790 units in stock. 2PC4081R,135 has 10,789 units in stock. 2SC4081T106Q has 105,100 units in stock. 2SC4081T106R has 120,400 units in stock. 2SC4081T106S has 15,300 units in stock. BC847AW RFG, BC847BW RFG, BC847CW RFG, and BC850AW RFG each have approximately 18,700-19,000 units in stock. 2SC6026CT-GR,L3F has 43,661 units in stock.
