Key Parameters

Substitute Part Grouping Explanation

Substitution is governed by matching or exceeding these critical parameters: transistor type, maximum collector-emitter voltage, maximum collector current, transition frequency, power dissipation, and package compatibility (SC-70, SOT-323). RoHS compliance, REACH status, and MSL are included to ensure quality, safety, and supply chain compatibility. All listed substitutes are surface-mount NPN BJTs in the SC-70/SOT-323 package, with appropriate electrical and environmental ratings conforming to those of the original part.

Key substitution parameters:

• Transistor Type
• Voltage - Collector Emitter Breakdown (Max)
• Current - Collector (Ic) (Max)
• Frequency - Transition
• Power Dissipation (Max)
• Package / Case
• RoHS and REACH Compliance
• Moisture Sensitivity Level (MSL)

Parameter Comparison

Engineering Selection Recommendations

The main part, 2SC4083T106P, is classified as "Not For New Designs." All listed substitute parts—2DD2652-7, BC848AW_R1_00001, and BC848W,115—are currently "Active," have RoHS3 and REACH compliance, and meet the specified Moisture Sensitivity Level (1, Unlimited). Each substitute is packaged in a surface-mount SC-70/SOT-323 case, offering compatibility for board layout and automated assembly. These compliance and status attributes assure the continued supply, environmental adherence, and processing reliability required for new and ongoing designs.

Frequently Asked Questions (FAQ)

Q: What fields must match when selecting substitute transistors in this category?
A: The key fields for substitution are transistor type (NPN), collector-emitter voltage (must meet or exceed original), collector current (must meet or exceed original), frequency (application dependent), maximum power dissipation, and package compatibility (SC-70/SOT-323).

Q: Are the substitute parts RoHS and REACH compliant?
A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected.

Q: Will the substitute package fit the existing footprint?
A: All substitutes use the SC-70 or SOT-323 package, compatible with layouts designed for the original 2SC4083T106P in UMT3/SC-70/SOT-323 outlines.

Q: Why is the 2SC4083T106P not recommended for new designs?
A: The product status is "Not For New Designs," indicating that the manufacturer does not support this part for future production design, prompting selection of current, active alternatives to ensure supply stability.

Q: Is moisture sensitivity consistent across all options?
A: Yes. The main part and all substitutes have an MSL rating of 1 (Unlimited), ensuring similar handling and storage requirements.

Q: What ensures electrical and mechanical compatibility between the original and substitutes?
A: Matching package type, RoHS/REACH compliance, and equal or higher electrical ratings for collector voltage, current, and power ensure the substitutes can replace the original part in qualified applications.
